Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] see Figure 1-Figure 4 The embodiment of the present invention provides a brake gap adjustment device, which includes a caliper body 1 and an adjustment mechanism 2. The caliper body 1 has a chamber 11, and the adjustment mechanism 2 is installed in the chamber 11. The adjustment mechanism 2 includes a cross bar 21 and The eccentric lever 22 arranged on the cross bar 21 can rotate around its own eccentricity, and then can push the cross bar 21 to move i...

Abstract

The invention relates to a brake, and provides a brake gap adjustment device, which includes a caliper body and an adjustment mechanism. The adjustment mechanism includes a cross bar and an eccentric lever. Each through hole is pierced with a rotation shaft. The axis is perpendicular to the rotation axis of the eccentric lever, and a pusher is provided at one end of each rotation shaft, and a sprocket perpendicular to the axial direction is arranged on the two rotation shafts, and the two sprockets are driven by a chain. And the two sprockets are respectively close to the middle positions of the corresponding rotating shafts along the axial direction; a pneumatic disc brake is also provided, including the above-mentioned adjusting device. In the present invention, when the eccentric lever is subjected to an external force, the two pushing parts can move along the axial direction of the rotating shaft through the threaded cooperation between the cross bar and the two rotating shafts, and then the gap adjustment of the corresponding friction plate can be realized, and the two rotating shafts The position near the middle adopts the transmission method of sprocket chain to ensure that the two rotate synchronously, and the consistency is very high.

Description

technical field [0001] The invention relates to a brake, in particular to a brake gap adjustment device and an air pressure disc brake. Background technique [0002] Pneumatic disc brakes, as a type of disc brakes, began in the 1990s and can be widely used in large passenger cars and trucks. Pneumatic disc brakes have fast heat dissipation, light weight, simple structure, and automatic adjustment of wear gap; especially high temperature resistance, stable braking effect, can significantly reduce braking distance, and provide reliable driving guarantee for vehicles. At present, the pneumatic disc brakes developed by various companies at home and abroad, especially the double-push rod pneumatic disc brakes, have many types of clearance self-adjusting mechanisms. However, the synchronization mechanisms of most structures use gears to synchronize the main and driven shafts, and the resulting system resistance is low. Stable, so it is not stable enough when adjusting the wear cl...
