BE2017 / 5273

Double freewheel clutch for a go-kart or go-kart, as well as mechanism and go-kart or go-kart that contain a double freewheel clutch.

The present invention first and foremost relates to a double freewheel clutch for a go-kart or go-kart.

More specifically, the present invention relates to a dual freewheel clutch for a go-kart or go-kart, which is intended for both forward and reverse free-wheel drive of the wheels of a go-kart or go-kart axle.

The double freewheel clutch has an input element that is intended to be driven by a drive of the go-kart or go-kart and an output element that is intended to drive the relevant wheels of the go-kart or go-kart.

There are already known go-karts or go-karts that are equipped with the aforementioned double freewheel coupling.

In these known go-karts a chain wheel is permanently mounted on the rear axle, this rear axle in turn being fixedly connected to the input element of the double freewheel coupling for driving a wheel, at least insofar as the axle is not in a free-running condition, in other words, does not rotate faster than the wheel to be driven.

BE2017 / 5273

The components of the double freewheel clutch of these known go-karts are furthermore mainly mounted in or in the vicinity of a drive wheel of the go-kart.

A major drawback of well-known double freewheel clutches is that they are rather difficult to assemble.

Since the double freewheel clutch in these known go-karts is located in a rather difficult to reach location in or near a wheel, its maintenance is also far from practical.

Another drawback of such a known freewheel clutch is that it has many parts that are an integral part of the drive of the rear axle of the go-kart such that it is difficult or even impossible to replace or exchange individual parts of the drive with other parts , for example to replace worn parts or to make adjustments depending on the size or muscle strength of the user.

The present invention then has also until target a solution to offer to one or more from the aforementioned or possible other disadvantages. More specifically, it is a target from the invention one so

to offer a compact possible double freewheel coupling, which can also be very sturdy and which

BE2017 / 5273 can be easily mounted, replaced or adjusted in a go-kart or go-kart.

The invention also aims at a very maintenance-friendly double freewheel coupling.

A further object of the invention is to provide a double freewheel clutch which is designed in such a way that its placement and operation in a go-kart or go-kart has little influence on or is as independent as possible from the operation and placement of other parts of the concerning go-kart or go-kart.

To this end, the invention relates to a double freewheel coupling for a go-kart or go-kart, as described above, and wherein the double freewheel coupling according to the invention also contains at least the following elements:

a mounting element intended to hang the double free running coupling on a frame of the go-kart or go-kart or to mount it on it;

- a housing rotatably mounted relative to the fastening element;

- a freewheel which at least partially extends into the housing and which is mounted rotatably with respect to the fastening means and with respect to the housing;

coupling means which allow to transmit a rotational movement with which the input element is driven to the output element for a rotational movement thereof and this in accordance with the relevant driving sentence, insofar as the driving speed of the input element does not exceed the rotation speed of the output element;

BE2017 / 5273 and in which the output element is intended to be fixedly connected to the axis of the go-kart or go-kart.

A very great advantage of such a double freewheel coupling according to the invention is that its starting element is intended to be fixedly connected to the axis of the go-kart or go-kart in which it is used.

After all, as has already been described in the introduction, the known double freewheel clutches intend to connect the driven shaft of the go-kart with the input element of such double freewheel clutch.

From this it automatically follows that the core of the double free running coupling is located between this axle and the wheel and therefore usually in the vicinity of or in the wheel.

In the case of a double freewheel clutch according to the invention, it is the other way around to intend to connect the axis of the go-cart with the output element of the double freewheel clutch.

An important advantage of this is that the double freewheel coupling can be fitted almost anywhere on this shaft.

Preferably, such a double freewheel clutch according to the invention is preferably mounted centrally in the axis of the go-kart, close to the chain drive, which is also always provided centrally, since this is the most logical position for a drive with pedals.

BE2017 / 5273

Another big advantage of such a double freewheel clutch design according to the invention is that the axle can be mounted separately in the frame of the go-kart, while the wheels of the go-kart can be fixedly mounted on this axle, which is quite a bit is simpler and more robust than what is known from the prior art.

Yet another advantage of a double freewheel clutch according to the invention is that it can be mounted directly to the frame or frame of a go-kart with a fastener, with all other parts of the double freewheel coupling suspended or rotatable from this fastener mounted around.

This again implies a strong simplification.

In a preferred embodiment of a double freewheel clutch according to the invention, the input element of the double freewheel clutch is formed by the freewheel wheel.

In this embodiment, a chain drive sprocket of the relevant go-cart or go-kart can easily be mounted on the freewheel to drive the freewheel.

Replacing or exchanging such a sprocket wheel is also very simple in this embodiment.

In a further preferred embodiment of a double freewheel clutch according to the invention it becomes

BE2017 / 5273 output element of the double freewheel clutch formed by the housing, whereby this housing must therefore be fixedly connected to the axis of the go-cart.

As will be shown in more detail later in the text, such an embodiment of a double freewheel clutch according to the invention is very compact and robust.

According to the invention, however, it is not excluded that the rollers are turned in which the housing of the double freewheel coupling forms the input element on which a gear or sprocket can be provided and in which the freewheel forms the output element to be fitted with the axis of the go-kart connected.

Also other possible embodiments are not excluded from the invention.

The invention also relates to a go-kart or go-kart mechanism comprising a double freewheel clutch according to the invention as described above, as well as a shaft.

Characteristic of such a mechanism according to the invention is the fact that the double freewheel coupling is centrally mounted on the shaft for the go-kart or go-kart, the output element of the double freewheel coupling being fixedly connected to the shaft.

BE2017 / 5273

This central position of the double freewheel clutch is very advantageous for mounting, replacement and maintenance.

Moreover, this is only possible due to a fundamentally different approach in which the axle of the go-cart is fixedly connected to the output element of the double freewheel coupling, such that mounting near a wheel of the go-kart is no longer necessary.

In a preferred embodiment of a mechanism according to the invention, a sprocket wheel is fixedly mounted on the entrance element of the respective double freewheel clutch.

Coupling or decoupling, respectively for driving the shaft or for running the shaft in a freewheel condition, naturally takes place between the input element and the output element of the double freewheel coupling, regardless of whether forward or reverse driving is involved.

In this embodiment of a mechanism according to the invention, this coupling and decoupling thus takes place between the shaft and the driving sprocket wheel, while in the known mechanisms for go-karts this functionality takes place between the shaft and a wheel mounted on this shaft with all the disadvantages. associated with this, for example in terms of mounting, maintenance and replacement of the double freewheel clutch and other components of the go-kart.

BE2017 / 5273

With a mechanism according to the invention as described above, it is relatively easy to replace the sprocket wheel, as well as the entire double freewheel clutch and so on.

In a further preferred embodiment of a mechanism according to the invention, the housing of the double freewheel coupling forms its output element and this housing is designed as a sleeve on which a lid is provided, the sleeve having a cylindrical wall and a bottom, the lid being the cylindrical wall covers on the side opposite the bottom, with the shaft extending centrally through the housing, the shaft being rigidly connected to the bottom and the lid having an opening through which the shaft extends.

In yet another preferred embodiment of a mechanism according to the invention, the freewheel of the double freewheel clutch forms its input element and the freewheel comprises a tubular section extending through the fastening element and the sprocket wheel being on the free end of the tubular section mounted outside the housing.

As will be further illustrated with reference to figures, the aforementioned embodiments are very compact and practical to use.

BE2017 / 5273

The invention also relates to a go-kart or go-kart that is provided with a mechanism according to the invention as described above.

Such a go-kart or go-kart is usually not really intended as a means of transport, but rather is used as a toy for children or young people, where it is not the intention to travel long distances with the go-kart or the go-kart.

Furthermore, such a go-kart or go-kart is typically powered by muscle power, for example, using chain-driven pedals or pedals or by pushing the feet off the ground.

Nevertheless, it is not excluded that the invention may also be applied to go-karts or go-karts that do serve as real means of transport and / or go-karts or go-karts that are provided with drive means, such as an electric motor or combustion engine.

A go-kart or go-kart according to the invention is typically characterized in that the axis of the mechanism is the rear axle of the go-kart or go-kart driven by chain driven pedals, with the dual freewheel clutch mounted in the center section of the the axle, where a sprocket wheel is mounted on the freewheel of the double freewheel clutch and the housing of the double freewheel clutch is firmly connected to the rear axle of the go-kart or go-kart.

The benefits of such a go-kart or go-kart are trivial in light of what was previously written with

BE2017 / 5273 relating to the double freewheel clutch and the mechanism according to the invention.

With the insight to better demonstrate the features of the invention, an example without any limiting character is described below, a preferred embodiment of a double freewheel coupling according to the invention, a mechanism according to the invention, as well as a go-kart or go-kart according to the invention. , with reference to the accompanying figures, in which:

figure 1 shows in perspective a part of a go-kart or go-kart according to the invention in disassembled condition;

figure 2 represents a bottom view according to arrow F2 in figure 1, wherein however the relevant part of the go-kart or shelter according to the invention is in an assembled condition;

Figure 3 is a section according to cut III-III shown in Figure 2;

figure 4 is a larger-scale perspective view of the parts indicated by F4 in figure 1 and representing a double freewheel clutch according to the invention in disassembled condition;

figures 5 to 8 show in perspective and on an even larger scale the parts of the double freewheel coupling, respectively indicated with the F5 to F8 in figure 4;

figure 9 is a larger-scale perspective view of the part of the go-kart which is indicated by F9 in figure and which represents a mechanism according to the invention;

BE2017 / 5273 figure 10 is a front view according to arrow F10 on the mechanism of figure 9;

Figure 11 is a section through the mechanism taken on the line XI-XI shown in Figure 10; figure 12 is a larger-scale perspective view of the part indicated by F12 in figure 9 and representing a double freewheel clutch according to the invention; and, Figure 13 is an enlarged cross-sectional view of the portion indicated by F13 in Figure 11 representing the same double freewheel clutch according to the invention.

The portion 1 of a go-kart or go-kart according to the invention shown in Figures 1 to 3 comprises a frame or frame 2, a mechanism according to the invention 3 and a pair of rear wheels 4 of the go-kart or go-kart.

The frame or frame 2 in this case is mainly formed by a pair of pleated and welded round metal tubes 5 on which other metal elements 6 are provided for mounting parts of the go-cart or go-kart not shown in the figure, such as a seat, a steering wheel, a chain drive and pedals, front wheels and the like.

The mechanism 3 according to the invention of the go-cart or go-kart mainly consists of a rear axle 7 on which the rear wheels 4 are to be mounted and of a double freewheel coupling 8 according to the invention.

BE2017 / 5273

This double freewheel clutch 8 according to the invention is shown in exploded view in figure 1 and in more detail in figure 4, while its parts are shown in an even larger scale in figures 5 to 8.

The rear axle 7 is not round over its entire length L.

executed but is about a portion 9 with length L ' executed flattened with intention parts of the double freewheel clutch 8 easily stuck on it to can monstrate. Double freewheel clutch 8 is double in the sense that she allows the go-kart or go-kart both in forward as

drive backwards via a chain drive not shown in the figures.

Here, the double freewheel clutch 8 is such that, regardless of the sense in which the chain drive tries to drive the rear axle 7 and the rear wheels 4, there can always be a freewheel of the rear axle 7 and the rear wheels 4 in the event that the chain drive cannot follow the driven parts, for example when a user of the go-cart keeps the legs on the pedals still or drives slower than the rear axle 7 and the rear wheels 4 are already rotating.

To this end, in the terminology used in this text, the double freewheel clutch 8 has an input element 10 which is intended to be driven by a drive of the go-kart or go-kart and an output element 11 which is intended to drive the relevant rear wheels 4 of the power go-kart or go-kart.

BE2017 / 5273

As shown in more detail in Figures 4 to 8 and in particular in the cross section of Figure 13, the input element 10 of the double freewheel clutch 8 in the embodiment discussed here is formed by a freewheel 12 and the output element 11 by a housing 13 .

The double freewheel coupling 8 furthermore comprises a fixing element 14 which is intended to hang the double freewheel coupling 8 firmly on the frame 2 of the go-kart or go-kart or to be able to mount it on it.

More specifically, the fastening means 14 is designed as a closing element 15 for the freewheeling wheel 12.

In this case it is the intention that this fixing element 14 is suspended from and fixedly connected to a suspension part 16 which is provided on the frame or frame 2.

In the embodiment of the figures, this suspension part 16 is designed as a metal plate 17 which, in the normal state of the go-cart, extends vertically from the frame 2.

In this case, a metal U-shaped recess 18 is provided in the metal plate 15, into which one end 19 of the fastening element 14 can be suitably inserted and which is flattened for this purpose in order to block it against rotation in the U-shaped recess 18.

BE2017 / 5273

All this is made more illustrative in Figures 1 and 3, for example.

Of course, completely different embodiments are not excluded from the invention.

The housing 13 of the double freewheel clutch 8 is designed as a sleeve 20 on which a lid 21 is provided.

This sleeve 21 has a cylindrical wall 22 and a bottom

23.

The cover 21 covers the cylindrical wall 22 on the side 24 of the housing 13 opposite the bottom 23.

The rear axle 7 extends from a first rear wheel 4 centrally through the bottom 23 and through the entire housing 13.

The rear axle 7 is hereby firmly connected to the bottom 23.

The cover 21 is provided with an opening 25 through which the rear axle 7 extends further on the side 24 of the housing 13 to the other rear wheel 4.

It is very characteristic of the invention that the double freewheel coupling 8 is centrally mounted on the rear axle 7 of the go-kart or go-kart.

This can only be achieved in that the output element 11, which in this case is formed by the housing 13, is fixedly connected to the rear axle 7.

BE2017 / 5273

The cover 21 in this case is fixed to the sleeve 20 using four bolts or screws 26.

The fastening element 14 partially extends inside the housing 13 and is mounted in this housing 13 by means of a ball bearing 27.

Or, in other words, which may be more appealing to the imagination, the housing 13 is rotatably mounted relative to the fastening element 14, since the fastening element 14 is to be considered as part of the double freewheel coupling 8 which is fixedly mounted on the frame 2 of the go-kart.

To this end, the fastening element 14 in this case is designed as a sleeve 28 with a tubular part 29 which has an internal part 30 contained in the housing and an external part 31 extending from the housing 13 through the opening 25 in the cover 21 of the housing 13.

Furthermore, a flange 32 is provided on the inner part 30 of the tubular part 29 of the sleeve 28, which forms a stop with which the sleeve 28 bears against the aforementioned ball bearing 27.

The sleeve 28 is thus mounted in the cover 21 of the housing 13.

BE2017 / 5273

The freewheel wheel 12 extends at least partially into the housing 13 and it is mounted rotatably with respect to the fastening means 14 and with respect to the housing 13.

The freewheel wheel 12 is herein provided with a tubular part 33 which extends through the fastening element 14 to outside the housing 13.

The freewheel 12 in this case forms the entrance element 10 of the double freewheel clutch 8, a sprocket 34 being fixedly mounted on the free end 35 of the tubular part 33.

It is clear that the sprocket wheel 34 should be regarded as a part of the chain drive of the go-cart, which is not shown in further detail, this part (like the rear axle 7) not really belonging to the actual double freewheel clutch 8 .

Such a sprocket 34 can be easily replaced, for example, by a sprocket 34 of other dimensions to adjust the gear ratio of the chain drive.

The freewheel wheel 12 has a part 36 in the housing 13 which is disc-shaped, coupling means 37 being provided on this disc-shaped part 36 in the form of spring-activated and compressible coupling elements 38 which can interact with the housing 13, in particular with grooves 39 and fands 40 provided on the inside of its cylindrical wall 22.

BE2017 / 5273

With this coupling means 37, a driving force applied to the sprocket wheel 34 can be transferred via the freewheel 12 to the housing 13 and this in accordance with the drive of the sprocket 34 and thus of the freewheel 12, at least insofar as the coupling elements 37 are not in the freewheel position. are activated as is the case when the sprocket wheel 34 lags behind the housing

13.

The freewheel wheel 12 is mounted in the bottom 23 of the housing 13 by means of a ball bearing 41.

Furthermore, in the embodiment discussed here, the freewheel wheel 12 is fitted over an bearing bush 42.

For the proper operation of the free running mechanism of the double freewheel coupling, a freewheel wheel switch 43 is preferably also provided between the fastening element 14 and the freewheeling wheel 12.

It is useful to bear the freewheel 12 with respect to the fixing element 14 by means of a ball bearing 44, which is shown by way of example in Figures 1, 4 and 6.

To this end, the side 45 of the flange 32 of the fastening element 14 opposite the ball bearing 27 can serve as a stop 46.

However, all this does not necessarily have to be the case, as illustrated by the cross section of Figure 13, in which such ball bearing 44 is not provided.

2017/5273 ₁₈ BE2017 / 5273

In both cases, however, the stop 46 of the fastening element 14 holds the freewheeling wheel 12 in place, and in that sense the fastening element 14 is also a closing element 15 for the freewheeling wheel 12.

The present invention is in no way limited to the embodiment of a double freewheel clutch 8, a mechanism 3 and a go-kart or go-kart according to the invention as described above, but such double freewheel coupling 8, such a mechanism 3 and a go-kart or a go-kart can be used in many shapes and sizes are made without departing from the scope of the invention.
