Description

Disk type braker

Technical field

The present invention relates to the car brakeing disk type braker, particularly relate to the clamp radially mount type disk type braker that is supported on vehicle body side along the bolt of disc radius direction.

Background technique

As shown in Figure 6, comprise in the disk type braker: disk 101; A pair of brake block 102, it is provided in its both sides to coordinate the state of coupling in the position of disk sense of rotation (left and right directions among Fig. 6) along disk 101 axial directions (direction about among Fig. 6); Clamp 105, its with coordinate coupling the state of the position of disk sense of rotation, be provided in its both sides along the disk axis and be separated along the disk direction and set, its inside have two pairs can chimeric slidably pushing brake block 102 the 103a of cylinder chamber, the 103b of

piston

104a, 104b; Supporting part, it is not (it illustrates) of vehicle body side stationary clamp 105.

This disk clamp its 105 along disc radius direction and parallel to each other, simultaneously by two the bolt mounting holes 107a of configuration that are separated in the disk sense of rotation, construction bolt is fixed on the supporting part and is radially mount type among the 107b.

Then, for the circulation of brake fluid,, be communicated with a pair of 103a of cylinder chamber, the 103b at disk sense of rotation outlet side of clamp 105 by the access 108 that between the bolt mounting holes 107b of disk sense of rotation outlet side and brake block 102, is provided with.In addition, also be communicated with at the adjacent 103b of cylinder chamber of disk sense of rotation with intermediate connection road 109.

As existing radially mount type disk type braker, make its middle position between bolt mounting holes 107a, the 107b of disk sense of rotation, at the middle position of the brake block 102 of disk sense of rotation and the middle position between piston 104a, the 104b in the disk sense of rotation all on the same position shown in symbol C11.

In the clamp 105 of as described radially mount type disk type braker, be necessary to form

bolt mounting holes

107a, 107b along the disc radius direction, be necessary to form access 108 in the hands-off position of bolt mounting holes 107b, and be to set brake block 102 to be necessary space portion 110 to be set in the position of not interfering this path 108 with disk sense of rotation outlet side.Therefore, as shown in Figure 6,, do not expand the distance L 11 between

bolt mounting holes

107a, 107b and the disk 101, and shorten bolt mounting holes 107a, the distance of 107b between the disk sense of rotation in order to realize clamp 105 miniaturizations.Like this, the amplitude L13 in the disk sense of rotation of brake block 102 will shorten, and braking ability may occur and reduce.

In addition, as shown in Figure 7, do not expand bolt mounting holes 107a, the distance L 11 of 107b and disk 101, and in order to ensure sufficient braking ability, just want to expand the amplitude L13 of brake block 102 in the disk sense of rotation, the space portion 110 that sets this brake block 102 is also expanded in the disk sense of rotation, when avoiding interfering, form access 108 and bolt mounting holes 107b, will be offset bolt mounting holes 107 in order to space out in the disk sense of rotation, 107b, its result, bolt mounting holes 107a, the interval L12 of 107b is strengthened, and makes clamp 105 become big.

Have again, as shown in Figure 8, expand the width of cloth L13 in the disk sense of rotation of brake block 102 in order to ensure sufficient braking ability, also to suppress the maximization of clamp 105 simultaneously, will suppress the expansion of the interval L12 of

bolt hole

107a, 107b in the disk sense of rotation, like this, the distance L 11 of

bolt mounting holes

107a, 107b and disk 101 is widened, as a result, the distance of disk 101 and

bolt mounting holes

107a, 107b is elongated, and clamp 105 is increased by the distortion that moment of rotation produces.

In addition, open as shown in the 2000-249173 communique, also can be formed in the clamp outside connecting tube structure that forms path is installed, but this occasion certainly will increase the part number, and cost is increased as the spy.

Summary of the invention

Similarly, in the 2nd embodiment, clamp 13 is corresponding with two pairs brake block, has two couples the 28a of cylinder chamber, 28b and two couples piston 18a, 18b.But also be not limited thereto, also brake block more than three pairs can be arranged as long as the logarithm of the logarithm that makes cylinder chamber and piston and brake block is corresponding.At this, the occasion that brake block more than three pairs is arranged, the right middle position of so-called brake block be meant the disk sense of rotation by the brake block of inlet side with by the middle position of the brake block of outlet side (connect and connect middle position between the straight line at two end part of disk sense of rotation of the brake block that leans on outlet side most) by the straight line at the two end part of the disk sense of rotation of the brake block of inlet side.

In addition, the 1st embodiment and the 2nd embodiment are same, the bolt mounting holes of clamp is two places, outside the bolt mounting holes that this two place is set, also can be in the disk circumference direction, the bolt mounting holes that the neutral position at this two place is provided with other again is used for clamping bolt, so that clamp is installed more firmly and improved the rigidity of clamp at vehicle body side.

The effect of invention

As described in detail above, disk brake of the present invention because with brake block in the disc rotary direction Middle position with respect to the middle position of the bolt mounting holes that is separatedly installed in the disc rotary direction to circle A certain lateral deviation in the entrance side of disc spins direction and the outlet side is moved and is set, both guaranteed brake block at disk The width of cloth of direction of rotation is long, also not be used in the clamp outside tube connector that forms access is installed, and need not expand again Bolt mounting holes and disk also need not be expanded in the interval of the bolt mounting holes that is separated in the disc rotary direction Distance, by the bolt mounting holes of expansion disc rotary direction outlet side and the interval of brake block, with regard to energy Enough therebetween it is set access uninterruptedly.

Thereby, guarantee the width of cloth in the disc rotary direction of brake block in order to ensure sufficient braking ability Long, can suppress the increase of number of components and size simultaneously, and suppress the distortion that produced by braking moment.
