Wheel edge circular ring type service parking brake

Abstract

The invention provides a wheel edge circular ring type service parking brake which comprises a left brake unit and a right brake unit which are symmetrically arranged at the left side and the right side. The functions and the structures of the left brake unit and the right brake unit are the same; the left brake unit and the right brake unit are each provided with a service brake system and a parking brake system; and a brake disc is arranged between the left brake unit and the right brake unit, shells of the left brake unit and the right brake unit are connected into a rigid body through longbolts, taper holes used for allowing pin shafts in the parking brake systems to be inserted therein are evenly distributed in the brake disc along the circumference, and the wheel edge circular ringtype service parking brake is formed, wherein a brake pad and a taper pin jointly complete the strong parking brake performance of the parking brake systems, reliable parking braking is achieved, theservice brake performance is improved, and the purposes of saving the arrangement space and reducing the self weight are achieved.

Description

technical field [0001] The invention belongs to the technical field of vehicle parking brakes, in particular to a wheel-rim circular ring type parking brake, which is applicable to all wheeled vehicles. Background technique [0002] So far, the commonly used wheel-side parking brakes are called air-break brakes; there are two problems with it, one is that the drum brake is not as good as the disc brake, and the disc brake caliper is only one-third of a circle First, it has a small pressure-bearing area and limited braking ability. Second, it has an air chamber and a control lever that takes up a lot of space, especially when used on a bridgeless independent suspension vehicle, which takes up too much space for the chassis. Not well arranged. The air break brake commonly used on large transport vehicles has a small pressure bearing area on the one hand, and on the other hand, only one brake can be installed on the side of the double wheel, which cannot solve the problem of i...

[0002] So far, the commonly used wheel-side parking brakes are called air-break brakes; there are two problems with it, one is that the drum brake is not as good as the disc brake, and the disc brake caliper is only one-third of a circle First, it has a small pressure-bearing area and limited braking ability. Second, it has an air chamber and a control lever that takes up a lot of space, especially when used on a bridgeless independent suspension vehicle, which takes up too much space for the chassis. bad arrangement

The air break brake commonly used on large transport vehicles has a small pressure bearing area on the one hand, and on the other hand, only one brake can be installed on the side of the double wheel, which cannot solve the problem of installing one on each of the two wheels. Due to the poor braking ability on the road, the sliding friction heats up seriously, and water is often used to cool down. In this way, in the cold winter in the north, the water flow will freeze the entire road, and the probability of accidents due to road slipping will increase. The safety factor is low and the slope is low. Weak ability
