Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc brake having an integral knuckle type support part, and more particularly to the structure of a temporary assembly including a holder used to hold the assembly including a caliper and friction pad.

Conventionally, there has been a desire for quantification of brake equipment as one of the equipment installed in vehicles, and various improvements and innovations have been made. The caliper, which is supported for mobility, and the friction pad, which is pressed against the rotor by this caliper, are assembled and supported by an integral knuckle type support part that is integrated with the knuckle that supports the wheel. Vin type disc brakes are also offered.

This is suitable for weight reduction because it has fewer parts than the known separate support that is fastened to the knuckle with bolts, etc., and has an advantage in structural strength against the pressure of brake torque. It is known as having a desirable configuration.

However, the integral knuckle type disc brake with this structure has the following problems. In other words, before it is assembled into a vehicle, the brake device must be constructed as an assembly made up of various parts, transported, and installed at the required assembly line for the vehicle. From a work perspective, when a large number of parts are assembled into an assembly in relation to each other, it is desirable to be able to handle the assembly as one unit. With knuckle-type disc brakes, there is nothing that determines the positional relationship between the caliper and the friction hat, so the handling work is often complicated.Especially when assembling the brake device, there are relatively large volume constraints on the position. For this reason, if an operator has to hold each caliper and friction pad in his or her hand while performing the work, the complexity of the work becomes a major cause of inefficiency.

One of the reasons for the complexity of this work is as follows.

That is, as shown in Fig. 11, the pad clip (1) is first attached to the integral knuckle type support part (1).
2), then the friction pad (3), and finally the caliper body (4), this caliper body is supported by an integral knuckle type support part. Regarding the bin slide mechanism, which is one of the normal sliding support devices, when inserting (screwing) the slide bolt (sometimes a bolt) that is pre-installed on the caliper body into the hole in the support part, it is necessary to Drilling a hole in the support part with a slide bin while supporting a heavy 8g caliper body in a fixed position is a bit tiring both mentally and physically for the worker.

From this point of view, the present invention provides a method of assembling a holder to hold the caliper and friction pad in a predetermined relationship in a predetermined relationship in an integral knuckle type brake device before assembling the caliper and friction pad in an integral knuckle type brake device to a vehicle, and applying a spring force to the holder. Alternatively, by using the tension force of the anti-rattle pad clip that is used even after the device is assembled, the anti-rattle pad clip can be used between the caliper and the friction pad in opposing directions (when assembled to the support part, the opposing effects in the rotor radial direction are removed). ) is provided so as to create a pressure on the caliper body, and with this spring force, the work of supporting the caliper body by simply pressing the slide pin is sufficient. It is characterized by:

Therefore, the gist of the present invention is to provide a sliding support device including a friction locking mechanism that is fixedly supported by an integral knuckle type support section and a sliding support device that includes a slide bin that is bolted and fixed to the support section; A holter is assembled between the caliper and the friction pad, and suspends the grinding pad from the caliper.

These 11 (by the spring force of an anti-rattle spring assembled as necessary between the rad and the caliper, or by the spring force applied to the holder, there is a spring force between the friction pad and the caliper in the rotor radial direction. It has a temporary assembly structure of a disc brake having an integral knuckle type support part which is characterized by giving reciprocal spring force.

The present invention will be described below with reference to embodiments shown in the drawings. □ Embodiment 1 In FIG.
a) constitutes the housing part of the hydraulic cylinder device, and the other leg part (
llb) constitutes a reaction part. Also this caliper U
A perforation opening (lid) in the radial direction of the rotor is formed in the saddle (11C) that straddles the rotor.

(11e) is one leg (11
It is an arm extending approximately in the circumferential direction of the rotor from a), and in this embodiment, a sleeve (c) serving as a slide pin is fitted through the boss at the tip of this arm (1e). .

The sleeve (6) has a cylindrical shape with both ends open, and rubber boots (1) and (2) are respectively installed between both end surfaces of the caliper arm and the outer periphery of the sleeve.

The sleeve (2) is fixed to an integral knuckle type support part (not shown) by a bolt 0 inserted into the cylinder of this sleeve (6).
) is supported so that the caliper (b) can slide in the rotor axial direction.

Although such a sliding support device is shown only on one side of the caliper in the figure, another pair is provided on the other side of the caliper 11u.

The target and moe are -q grinding hats for pinching the rotor from both sides, and after the brake device is set to t1, the ears on the upper corners of both tools 11 shown in the figure are attached to support parts (not shown). It is supported by hooking and engaging.

In addition, the features of this Embodiment 1 are as follows:
(Drill holes in the ears of the IQ, and pass the bent tip side of the holder spring (M spring) OQ attached to the caliper (lη) through these holes, and
The holder spring i+Q applies a spring force to separate the caliper and the dark rubbing pad in opposite directions when the holder spring i+Q is used to suspend the pad Q5, (1!9), and the positional relationship between the caliper and the dark rubbing pad when assembling the device. It lies in the fact that it has been made to work.

The shape of the Holder Gering 04G is that one M spring material is oiled, and the center surface is hooked into a caliper saddle (110).
One (outer side) friction pad α1 is inserted into and engaged with the central opening (lid) of the
According to such a configuration, the friction pads 05, (15) are provided so as to extend in the rotor axial direction from the back surface thereof and pass through the ear holes (15a), (15a) of the pair of friction pads 05, (15). The subanonymous body including the sleeve and caliper of the sliding support device can be handled as a set of components, and when it is assembled into the support part of the integral knuckle, which is a fixed part of the vehicle, the plaster hat can be set in a predetermined position. Then, while lightly pressing the caliper σ■ against the spring force of the holder spring Q→, locate the screw hole in the support part with the bolt 04 fitted into the sleeve (6), and screw it into the sub-anonymous body. Assembling the caliper IJfI has the advantage of being much easier than when screwing in the bolts while supporting the relatively loud caliper IJfI by hand. There is.

Of course, in the first embodiment, a pad clip may be interposed between the support part and the four-part pad.

The holder spring α→ may be removed from F(Z) after the subanonymous body is assembled, and then reused.

Also, this implementation 1+! I1 can also be applied to the case where an anti-rattle spring αη is installed between the caliper u) and the friction pad (l) to prevent backlash after the device is assembled, as shown in Fig. 3. in case of,
As the mutual spring force between the caliper and the friction pad used when assembling the sub-anonymous body, the spring force of the anti-rattle spring can be used as is. Therefore, in this case, the spring force of the holder spring QQ as explained in FIG. 2 is not particularly necessary, and it may be one that merely provides a suspending function.

Embodiment 2 In Fig. 4, the holder 0 → is suspended so as to straddle the upper surface of the saddle (IC) of the dried Yariba (0) in the circumferential direction of the rotor, and the holder 0 → is suspended so as to straddle the upper surface of the saddle (IC) of the dried Yariba (0) in the circumferential direction of the rotor. It shows what was made to last.

When using this type of holder q→, as shown in the figure, a type in which the spring C11 is attached to an anti-lat that exerts opposing spring forces in the rotor radial direction between the caliper (b) and the friction pad α9 is used. Must have disc brakes.

Even in the case of this implementation [++12], it is easy to handle as a sub-anonymous body, and when assembling to the vehicle support part, the slide bin can be fixed to the support part by simply pressing the caliper (1◇) lightly. The advantage of being able to perform the work easily is almost the same.The above description shows the embodiment of the present invention, and the present invention is not intended to be limited to these examples. Naturally, for example, the structure of the sliding support device may be of a type in which the bolt directly forms a slide pin, or various other modifications may be considered.

As described above, the temporary assembly structure of a disc brake having an integral knuckle type support part according to the present invention uses a holder member to easily attach a sub-assembly body including a caliper and friction pads to a heavy machine. It has the effect of making it possible to assemble the vehicle as well as making it easier to assemble it into a vehicle, making it extremely useful.
