Description

The invention relates to a device for adjusting the toe or camber of a vehicle according to independent claim 1. The prior art is referred to by way of example DE 102 42 195 A1 referenced.

In order to set a track or a camber of a vehicle, an eccentric screw known from the prior art is required.

Different adjusting screws for adjusting the camber or the lane of a two-lane vehicle are known from the prior art. A well-known design is a so-called "Hold and Drive" screw with an eccentric support. The screw used here comprises a screw head which is provided with an eccentric. The free end of the thread section of the screw merges into a hexagon or hexagonal shape. This hexagonal or six-round shape enables one-sided assembly without holding the screw head.

Such an eccentric screw for toe or camber adjustment of a vehicle is from the DE 102 42 195 A1 known.

The accessibility to the eccentric screw for camber or track adjustment is subject to different prerequisites or boundary conditions in different setting situations, such as in vehicle production in assembly or in rework or in service.

The cited eccentric screw from the prior art enables the screw to be adjusted, held and tightened only from one side, but this screw shape still has disadvantages with regard to accessibility. So the eccentric screw from the DE 102 42 195 A1 can only be dismantled in one (axial) direction, as the screw head blocks one axial direction. Furthermore, although it is possible to ensure the screw setting and the retention from only one side in the assembly, depending on the direction of the screw, the tightening of the nut is only possible from a specific, precisely this side. In some situations, in turn, bilateral access is required to tighten the mother.

These restrictions lead to a higher assembly and disassembly effort and thus to a higher complexity and costs.

It is therefore the object of the invention to provide a device for setting the toe or camber of a vehicle and a vehicle with such a device, which device ensures more flexible toe or camber setting and more flexible and simplified assembly and disassembly.

The object is achieved by a device for setting the track or camber of a vehicle with the features of claim 1 and a vehicle with the features of the independent claim 6. Advantageous training and development are the content of the subclaims.

The device according to the invention comprises a threaded bolt with a threaded section.

A holding element can be held between a first threaded bolt side and a second threaded bolt side. This holding element is preferably designed as a vehicle part, in particular as a vehicle bearing, such as a rubber bearing, for example.

To ensure a camber or toe adjustment, an eccentric disc can be attached to each threaded bolt side, which can be screwed against the holding element by means of a nut and the holding element is thereby screwed against another component of the vehicle, for example against a rear axle carrier.

Such a rubber mount, which sits between two straps of the rear axle carrier, is preferably held by pressing the straps of the rear axle mount against the rubber mount by tightening the screw. If such a screw connection is successful, the camber or the vehicle's track can be adjusted.

So that the eccentric disk, which is attached to the first threaded bolt side, can be fixed axially (that is, along the bolt axial direction), it is provided that the first threaded bolt side comprises a stop. This stop is designed such that an eccentric disk plugged onto the first threaded bolt side can be axially fixed with the nut on one side and the stop on the other side. For example, the outside diameter of the bolt or the outside diameter of the thread can be made smaller at one point, so that the resulting edge realizes such a stop.

On the second threaded bolt side, no such stop is specifically provided in the threaded bolt. Instead, it is provided that a safety element on the second threaded bolt side ment can be arranged to axially secure or position the nut. Such a securing element is preferably a lock nut or a suitable securing ring.

This embodiment enables the device to be used for different holding elements with different widths or different geometrical designs. In the case of a preferred rubber bearing as the holding element, the device according to the invention can then be used for several bearing variants or bearing core variants with different widths or clamping lengths.

So that each of the two eccentric disks can be connected to the threaded bolt in a non-rotatable or non-rotatable manner, at least one groove (preferably formed in the axial direction of the bolt) is provided on each threaded bolt side on the threaded section. Two or more grooves are preferably provided on each threaded bolt side.

The grooves are arranged on the threaded section of each threaded bolt side in such a way that the eccentric disks, viewed in the radial direction of the bolt, can be aligned ideally or identically to one another.

It is also provided that the threaded bolt does not have a screw head in the sense of a screw. Rather, according to the invention, both threaded bolt ends each comprise a shape designed to receive a tool in a form-fitting manner.

Such a formation is preferably designed as a recess for a commercially available tool.

The formation is particularly preferably arranged on the end face of each threaded bolt side.

For example, this formation can be designed as a standardized or standard external hexagon or external hexagon.

Alternatively, other suitable geometric designs, such as a hexagon socket or a multiple socket, are also conceivable.

In any case, this formation offers a contact surface for a tool, which tool is used to hold the threaded bolt when setting the track or the camber or for assembling or disassembling the device.

The fact that both threaded bolt ends each include such a formation can ensure that a named retention of the threaded bolt can take place on the first threaded bolt side as well as on the second threaded bolt side, depending on the accessibility to the device.

Furthermore, the device according to the invention enables dismantling both starting from the first threaded bolt side and starting from the second threaded side. Mutual removal or dismantling and assembly is thus made possible.

In order to save assembly time, in a preferred embodiment of the subject matter of the application, the aforementioned tightened nut with the eccentric disk is already pre-assembled on the first threaded bolt side, so that assembly in such a case is limited to that threaded bolt side which includes the stop on the threaded bolt in order to axially secure the eccentric disk.

Furthermore, the device makes it possible to adjust the toe or camber of the vehicle from both sides, that is to say from the first threaded bolt side as well as from the second threaded bolt side.

In addition to the aforementioned device for adjusting the toe or camber of a vehicle, a vehicle is claimed according to the independent claim 6, which comprises a device according to the invention according to one of claims 1-5.

The vehicle comprises in particular a named threaded bolt with a threaded section, a vehicle part being held between the first threaded bolt side and the second threaded bolt side. As already mentioned, the vehicle part is preferably a mounting, in particular a rubber mounting or a rubber mounting.

The vehicle part thus forms the two threaded bolt sides by means of an intermediate arrangement.

An eccentric disk is attached to both sides of the threaded bolt. The eccentric disks are each screwed against the vehicle part by means of a nut.

In an advantageous embodiment, the nut and the eccentric screw on the first threaded bolt side are already preassembled on the threaded bolt, while the eccentric disk on the second threaded bolt side is a washer that is loosely attached during the assembly process.

As already mentioned, the threaded section of the first threaded bolt side comprises a stop which fixes or secures the eccentric disk of the first threaded bolt side axially between the holding element and the nut.

A securing element is arranged on the second threaded bolt side for axially fixing the eccentric disk or the nut. The named nut is arranged between the eccentric disk and the securing element. As already mentioned, the securing element is preferably designed as a lock nut or securing ring.

As also already stated above, each threaded section of a threaded bolt side comprises at least one groove running in the axial direction of the bolt. The grooves are designed in such a way that the eccentric disks are aligned identically to one another in the radial direction and are non-rotatably connected to the threaded bolt.

Both threaded bolt ends each include a shape designed to receive a tool in a form-fitting manner, which has already been explained above.

These and other features emerge from the claims and the description also from the drawing, the individual features being implemented individually or in combination in the form of sub-combinations in one embodiment of the invention and representing advantageous and individually protectable designs for which protection is claimed here.

In the following, the invention is explained further using an exemplary embodiment. All features described in more detail can be essential to the invention.

The single figure shows a schematic sectional view through a vehicle part 1 of a vehicle according to the invention which comprises a device according to the invention.

The vehicle part 1 is through a threaded bolt that penetrates this 2 held. The threaded bolt 2 includes a threaded portion 3 and in each case a formation in the form of an external hexagon arranged at the two ends of the threaded bolt 4th .

This threaded bolt is spatially created by the vehicle part 1 in a first threaded bolt side 2.1 and a second threaded bolt side 2.2 which threaded bolt sides 2.1 , 2.2 each at least approximately perpendicularly from a contact surface of the vehicle part 1 stretch.

On both sides of the threaded bolt 2.1 , 2.2 is an eccentric disc each 5 attached, each by a nut 6th against the vehicle component 1 is screwed.

On the first threaded bolt side 2.1 is the eccentric disc 5 by an axial stop 7th of the threaded bolt 2 axially secured. The eccentric disc 5 the second threaded bolt side 2.2 is not secured axially by such a stop. Instead there is a lock nut 8th in addition to the already existing mother 6th arranged which the eccentric 5 on the second threaded bolt side 2.2 axially secures. Through this control nut 8th a later toe or camber adjustment and a tightening of the connection can also be made from the first threaded bolt side 2.2 are made possible and the axial position of the eccentric disc 5 can be ensured.

So that the eccentric discs 5 each non-rotatably with the threaded bolt 2 are connected, includes each threaded bolt side 2.1 , 2.2 at least one axially extending groove 9 . The eccentric discs 5 grip positively into the respective groove 9 so that it is non-rotatable or non-rotatable on the threaded bolt 2 are arranged.

The grooves 9 are in this way on the respective threaded bolt side 2.1 , 2.2 arranged that the two eccentric discs 5 viewed radially are aligned in the same direction to one another.

In the following, the flexibility of the device according to the invention with regard to the accessibility to the device in the assembly, in the reworking and in the dismantling is to be explained with reference to the figure.

When assembling the device shown, the threaded bolt 2 with can be introduced from the left side of the vehicle part viewed in the figure in the direction of the right side. It is provided that the eccentric disc 5 the first (in this case the left) threaded bolt side 2.1 as well as the (already tightened) nut 6th this side 2.1 is already pre-assembled on the threaded bolt.

Then the eccentric disc 5 as well as the mother 6th the second (in this case the right) threaded bolt side 2.2 threaded from the right side.

By turning one of the two external hexagon edges 4th becomes the eccentric disc 5 adjusted and thus the track or the fall of the vehicle set. Here it is possible for an operator or fitter, depending on the accessibility to the device, either on the right or on the left external hexagon 4th to turn the device to adjust the camber or toe.

Then the mother can 6th on the second (in this case the right) threaded bolt side 2.2 be tightened and through the lock nut 8th secured.

If the camber or the vehicle's lane is to be adjusted later, for example in rework in vehicle production or in service, depending on the accessibility of the device, it can then be selected whether the adjustment is to be made exclusively from one side or from both sides. It is also possible to select from which side the setting can be made and which can be used for tightening.

For example, is only the second threaded bolt side 2.2 (in this case the right side of the threaded bolt) is accessible, so the lock nut 8th as well as the mother 6th on this page 2.2 be loosened and the track or the camber over the external hexagon 4th the second threaded bolt side 2.2 (In this case the right threaded bolt side 2.2 ) can be set. The mother 6th the left threaded bolt side 2.1 remains through the aforementioned fixed stop 7th biased. After adjusting the track or the camber, the mother can 6th and the lock nut 8th must be tightened again on the right side of the threaded bolt.

On the other hand, it is only the first, in this case the left side of the threaded bolt 2.1 accessible, so can the mother 6th the first or the left side of the threaded bolt 2.1 are loosened and the camber or the track over the external hexagon 4th the left threaded bolt side 2.1 can be set. Because the mother 6th and the lock nut 8th the right threaded bolt side 2.2 are firmly tightened, holding is enabled and the axial position is ensured.

Then the mother 6th on the left 2.1 dressed again.

If it should be necessary to dismantle the device, this can be done from both sides of the device, depending on the accessibility.

Either the mother can do this 6th or the lock nut 8th On the right side 2.2 or the mother 6th the left side 2.1 be solved. Then the mother can 6th and the eccentric discs 5 be pulled off and the threaded bolt 2 over one of the two sides 2.1 , 2.2 be dismantled.

The cited invention thus enables the device to be assembled and disassembled from both sides of the vehicle part 1 . Furthermore, the toe or camber adjustment can be made from both sides 2.1 , 2.2 of the threaded bolt 2 take place. The holding on and the subsequent suit is also from one of the two sides 2.1 , 2.2 individually or from one side at a time 2.1 , 2.2 possible.
