Abstract

The invention belongs to the technical field of automobiles, and particularly relates to an independent parking EPB brake caliper device. The device comprises an EPB motor, an EPB parking mechanism, apiston, EPB calipers, a guide pin, a friction plate, a brake disc, a rectangular sealing ring, a clamp spring, a friction plate return spring and a support. According to the device, the arrangement requirement can be met without using brake fluid, the independent parking function of a heavy-load vehicle can also be realized when the independent parking EPB brake caliper device and a service brakecaliper are jointly arranged beside rear wheels of the vehicle, and the technical blank that the arrangement space of the heavy-load vehicle is limited and the service brake requirement and the parking brake performance cannot be both met is filled.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to an independent parking EPB brake caliper device. Background technique [0002] With the development of automotive electronic control systems in the direction of integration and intelligence, the caliper integrated electronic parking system MOC EPB with faster response and more precise control gradually occupies a dominant position in passenger cars, and is also used in light trucks. more and more widely. EPB is also an important part of brake redundancy in the intelligent driving system. [0003] In addition, EPB also provides emergency braking function. Normally, the EPB system will notify the ESP to perform braking action (activate ESP dynamic deceleration braking). In the case of abnormal ESP response, EPB also provides independent braking functions (rear wheel anti-lock dynamic braking, failure braking), to ensure that in the case of ESP system failure, it can be compl...
