Description

Integrated brake caliper assembly

Technical Field

The invention belongs to the field of vehicle brakes, and particularly relates to an integrated brake caliper assembly.

Background

The brake caliper assembly is used as an execution terminal of a whole vehicle brake system and is frequently used in the use process of a vehicle, the dragging force of the brake caliper assembly influences the energy consumption utilization rate of the whole vehicle, a part of power which is originally transmitted to wheels for driving the vehicle is consumed by dragging of the brake caliper assembly, and the visual description is that the vehicle is originally normally driven, and as a result, the brake caliper assembly drags the wheels to try to stop the rotating wheels. For vehicle users, the intuitive expression is to reduce the cruising duration (especially for pure electric vehicles) and increase the fuel consumption per hundred kilometers. Because a part of energy does useless work, the dragging force of the brake caliper assembly is converted into useless heat energy to be dissipated in the air.

Although the caliper assembly has been studied for many years, no automobile manufacturer can achieve the desired level of 0 n.m. of drag of the caliper assembly. Splayed return springs in various shapes are generally adopted to realize the active return function of the friction block. An exploded view of the brake caliper assembly is shown in FIG. 1: pincers body support 1 links together through the pilot pin with pincers body 6, 2 joints of clamping spring leaf are in the guide way of pincers body support 1, splayed return spring 5 both ends are inserted in the aperture of interior clutch blocks 4 and outer clutch blocks 3 (the depth of insertion generally is more than 8 mm), make three (interior and exterior clutch blocks and splayed return spring 5) link together, interior clutch blocks 4 and outer clutch blocks 3 pass through both ends joint in the clamping spring piece, finally form a braking pincers assembly.

Description of the working principle: a. after a driver initiates a braking operation action, a brake system hydraulically pushes a piston in a brake caliper body to move towards a brake disc, a friction block is pushed to move along a guide groove of a clamping spring piece and is finally tightly pressed on the brake disc, in the process, splayed return springs connecting the inner friction block and the outer friction block are close to each other along with the inner friction block and the outer friction block, the distance between two ends is gradually reduced, the splayed return springs generate compression deformation per se, elastic potential energy trying to flick the inner friction block and the outer friction block is formed, but the potential energy is far smaller than the hydraulic thrust applied to the friction blocks, the splayed return springs cannot be unfolded to return to a natural state, and the elastic potential energy is temporarily stored. The friction between the brake block and the brake disc generates heat, and the speed of the running vehicle is reduced after the kinetic energy of the running vehicle is converted into heat energy, so that the aim of braking and decelerating is fulfilled. After the driver continuously brakes, the kinetic energy of the vehicle is gradually reduced until the vehicle stops running and stops, and the purpose of braking and stopping is achieved. b. After braking is relieved, hydraulic pressure of a braking system is unloaded, hydraulic pressure on the back plate of the friction block is eliminated and can be almost ignored, at the moment, elastic potential energy stored by the splayed return spring during braking promotes the spring to be naturally expanded in a compressed state, and the two ends push the inner friction block and the outer friction block to move away in a back-away direction, so that the brake disc is separated, and the purpose of reducing drag force (friction between the friction block and the brake disc) of the brake caliper assembly is achieved.

The combined technology of the splayed return spring and the clamping and positioning spring piece is a common scheme for reducing drag of the brake caliper, is widely popularized and used by various automobile manufacturers at present, and is easy to realize. One is responsible for the clamping and positioning of the friction block, and the other is responsible for the return of the friction block. But the contribution to reducing the drag of the brake caliper assembly is small, and the level that the drag force of the brake caliper assembly is less than or equal to 3N.m can be basically realized. The reason is that, as shown in fig. 2, the splayed return spring 5 is positioned at the edge of the friction block, the return force applied to the friction block is not on the central linebase:Sub>A-base:Sub>A of the friction block, andbase:Sub>A force arm L always exists, so thatbase:Sub>A turning moment around the central line of the friction block is generated, the friction block cannot smoothly move along the guide groove of the clamping spring piece, and the elastic potential energy is not fully utilized to enable the friction block to move along the axial direction.

An upwardly extending vertical portion 24 is connected above each of the retaining grooves 23, the vertical portion 24 is provided with a projecting arm 25 (see also fig. 6) projecting obliquely downward in a direction close to the inlay holder, and a lower surface 251 of the projecting arm 25 abuts against the caliper body holder 10. As shown in fig. 6, two extension arms 25 on both sides of each integrated return spring piece 20 in the wheel axial direction are respectively provided with a limiting protrusion 26 oppositely arranged in the wheel axial direction for limiting the degree of freedom of the integrated return spring piece 20 in the wheel axial direction.

The side of the bottom surface 221 of each guide groove, which is far away from the return tongue 21, is provided with a second guide tongue 29 which extends in the axial direction of the vehicle, and the end of the second guide tongue 29 is arranged obliquely in the direction far away from the return tongue 21.

In this embodiment, after the integrated return spring piece 20 is mounted to the caliper body bracket 10, the two limit protrusions 26 cooperate with the limit side surfaces 13 (see fig. 10) of the caliper body bracket 10 to limit the axial degree of freedom of the integrated return spring piece 20. The integrated return spring plate 20 is restrained from moving upwardly relative to the caliper body support 10 by the lower surface 251 of the projecting arm 25 engaging the inclined surface 14 (see fig. 10) of the caliper body support 10. The downward movement of the integrated return spring piece 20 relative to the caliper body bracket 10 is limited by the abutment of the upper surface 231 of the limit groove 23 with the upper surface of the limit boss 12 of the caliper body bracket 10 (see fig. 10). The lower end of the integrated return spring piece 20 is restricted from moving to the inner side (i.e., the left side in fig. 11) with respect to the caliper body bracket 10 by the bottom surface 221 of the guide groove abutting against the first groove 11 (see fig. 10) of the caliper body bracket 10, and the upper end of the integrated return spring piece 20 is restricted from moving to the inner side (i.e., the left side in fig. 11) with respect to the caliper body bracket 10 by the side 271 of the inclined portion 27 facing the caliper body bracket 10. The two limiting protrusions 26 and the four limiting surfaces can firmly clamp the integrated return spring piece 20 on the caliper body bracket 10. The first and second guide tongues 28, 29 may be used for directional guidance of the inner and outer friction blocks 40, 30 for mounting and dismounting on the integrated return spring plate 20.
