Abstract

The invention discloses an electronic parking braking caliper special for parking braking. An outside braking block and an inside braking block are correspondingly installed on a main caliper body anda vice caliper body, a connecting plate is fixedly installed on the axle of a rear axle, a guiding hole for a caliper body guide pin and a caliper body guide pin sleeve to penetrate through is formedin the main caliper body, the caliper body guide pin sleeve is installed in the guiding hole of the main caliper body in a sleeving mode, the caliper body guide pin penetrates through the caliper body guide pin sleeve and is connected to a threaded hole of the connecting plate through a thread, and thus the main caliper body is connected with the connecting plate; and a caliper body return springis connected between the end part of the end, away from the connecting plate, of the caliper body guide pin and the main caliper body, and thus the main caliper body moves elastically in the axial direction of the caliper body guide pin shaft. According to the electronic parking braking caliper, a non-bracket structure is adopted, and the purposes of zero dragging, light weight, simple structureand good product assembly process of the braking caliper are achieved.

Description

Technical field [0001] The invention relates to an electronic parking brake caliper, in particular to an electronic parking brake caliper dedicated to parking brake. Background technique [0002] For some models that have higher requirements on the rear axle braking force and need to have the parking function, the solution of installing a single opposed multi-piston fixed caliper or floating caliper cannot satisfy both the driving braking force and the parking braking force. The design of dual calipers appeared accordingly, one of which was an opposed multi-piston fixed caliper, dedicated to service braking, and the other was a floating caliper, dedicated to parking brake. [0003] An existing electronic parking brake caliper dedicated to parking brakes is based on a conventional bracket fixed and caliper body floating structure. The oil inlet and bleed screws related to the hydraulic brake system are removed, and the caliper body, Bracket, piston, inner and outer brake block asse...
