The disc brake has the advantages of fast heat dissipation, light weight, convenient adjustment, good high temperature resistance, large and stable braking force, better braking effect and the like compared with a drum brake, so the application of the disc brake is more and more mature and wide. The brake caliper is one of the main components of the disc brake and is powered by hydraulic pressure, and the main components include caliper body, support, piston, sealing ring, brake block, spring leaf, etc. When braking, the piston advances under the action of hydraulic pressure to push the brake block to clamp the brake disc, so that the brake block and the brake disc are rubbed to generate braking torque to force the automobile to decelerate or stop; after the brake is released, the piston returns under the action of the deformation return force of the sealing ring, so that a certain gap is formed between the brake block and the piston, and the brake block is separated from the brake disc under the action of the throwing force of the brake disc. When the hydraulic pressure of the brake is released, the residual rotation resistance torque of the brake disc is the dragging torque. The low-drag capability of the traditional brake caliper is far from meeting the requirement of the existing customer on low oil consumption, so more and more calls are required to speed up the pace and further reduce the drag torque of the brake caliper.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Example 1.

As shown in fig. 1-5, the embodiment provides a low-drag spring leaf with return function, including spring leaf body 1, be equipped with the installation department 11 that is used for installing the brake pad on the spring leaf body, installation department 11 is the design of taking open-ended frame shape, be equipped with the canceling release mechanical system 12 that is used for making the brake pad reset in the installation department 11, the top that the installation department 11 is close to in the perk of upper end of canceling release mechanical system 12, and the lower extreme links to each other with the bottom of installation department 11, canceling release mechanical system 12 includes an elastic circular arc holding surface 121, and under the composite state, the bottom and the circular arc holding surface 121 butt of brake pad.

The utility model discloses a take low dragging spring leaf of function of returning to throne, when the assembly goes into braking pincers assembly, the lower extreme of brake pad 2 contacts with circular arc holding surface 121 among the canceling release mechanical system 12, when the braking, caliper body clamp force forces brake pad 2 to press from both sides tight brake disc 3, the clamping process is because circular arc holding surface 121 has elasticity can produce and warp, circular arc holding surface 121 produces horizontal component F1 and vertical component F2, wherein vertical direction component F2 can be with the outside jack-up of friction disc, it is less to make the normal pressure of friction disc, thereby reduce the sliding resistance of brake pad 2, low because of the rigidity of the spring leaf, the clamp force is more stable controllable, the too tight and too loose problem of spring leaf pressure because of the machining dimension deviation leads to has been avoided.
