Problems solved by technology

However, optimizing the size of the seal groove will affect the value of the brake fluid consumption of the brake caliper, and it is necessary to evaluate the driver's brake pedal feel; increasing the stiffness of the brake caliper will affect the noise and brake vibration performance of the brake caliper , it is necessary to constantly adjust the size of the brake caliper, which increases the development cost; increasing the return spring of the friction plate is affected by the wear of the friction plate

Abstract

The invention discloses a vehicle braking type brake caliper. The vehicle braking type brake caliper comprises a shell, a piston and a friction plate. The piston can slide in the shell and is used for pushing the friction plate. The piston is internally provided with an adjusting nut, an adjusting threaded rod and a braking tray. The adjusting nut is in threaded connection with the adjusting threaded rod. The braking tray is arranged outside the positioning end of the adjusting threaded rod in a sleeving manner. The braking tray is fixedly connected with the shell. A drive spacer is also arranged in the braking tray and arranged outside the positioning end in a sleeving manner. A drive spring is arranged between the drive spacer and the braking tray in the axial direction. A return spring is arranged between the positioning end and the braking tray in the axial direction. The piston of the vehicle braking type brake caliper achieves mechanical returning through the drive spring and the return spring. After braking is relieved, the dragging moment between the friction plate and a brake disc is reduced. Moreover, the cost is low, and the effect is small.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a parking brake caliper. Background technique [0002] The drag requirements of brake calipers in the automotive industry are becoming more and more stringent. Brake caliper drag interacts with customer perceived quality of the brake system such as brake pedal feel, brake noise, and brake judder. When optimizing caliper drag, it is essential to evaluate pedal feel, brake noise and brake judder across the vehicle. [0003] The return of the existing brake caliper piston restores the deformation through the sealing ring. The sealing ring is a rubber part with non-linear characteristics. The greater the pressure, the smaller the return stroke, the smaller the disc gap, and the greater the drag of the brake caliper. [0004] Generally, the dragging of the brake caliper can be reduced by optimizing the size of the seal groove, increasing the stiffness of the caliper and increasing the re...
