Problems solved by technology

But at present, the friction block is actually separated by the rotation of the brake disc to separate the friction block from the brake disc. However, due to the friction between the caliper bracket and the friction block, the separation effect is not obvious, and the vehicle is released. After braking, there is still dragging between the friction block and the brake disc, and the contact between the friction block and the brake disc will also affect its heat dissipation, which will make the temperature of the friction block continue to rise, aggravate the wear of the friction block and brake disc, and cause damage to the brake system. Detrimental effect on dynamic performance

Embodiment Construction

[0014] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, the present invention provides a disc brake with a friction block return structure, which can make the friction block return to the initial position in time after the brake is released, improve the heat dissipation conditions, and avoid friction between the friction block and the brake disc. .

[0015] The technical solutions of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Such as figure 1 As shown, the disc brake with the friction block return structure in this embodiment includes a brake disc 7, friction blocks 3, 5 located on both sides of the brake disc 7, and a caliper supporting the friction blocks 3, 5 The bracket 6 , the caliper 2 pushing the friction blocks 3 , 5 along the axial direction of the brake disc 7 , and the...

Abstract

The invention discloses a disc brake with a friction block return structure. The disc brake comprises a brake disc, friction blocks located at two sides of the brake disc, a clamp body bracket supporting the friction blocks, a clamp body pushing the friction block along the axial direction of the brake disc and a friction block pressing plate at one side of the friction blocks, and the middle part of the friction block pressing plate is provided with an elastic element which is inclined towards the axis of the brake disc and can deform elastically along the direction vertical to the axis of the brake disc. The disc brake enables the friction blocks to return to the original position in time after brake removal, and ensures that the radiation condition is improved and the delayed friction between the friction blocks and the brake disc can be avoided.

Description

technical field [0001] The invention relates to a disc brake, in particular to a disc brake with a friction block return structure. Background technique [0002] With the advancement of automobile technology and the improvement of public safety awareness, more and more disc brakes are used in automobiles, including heavy-duty tractors, trucks and construction vehicles are equipped with disc brakes. The friction block of the disc brake cooperates with the brake disc. When the vehicle is braked, the disc brake caliper pushes the inner and outer friction blocks supported by the caliper bracket to move towards the brake disc. Squeeze friction produces braking force. [0003] Generally speaking, after the brake is released, the thrust of the caliper body is canceled, and the force of the friction block pressing the brake disc is also reduced, and the contact between the friction block and the brake disc should be out of contact. But at present, the friction block is actually se...
