Abstract

The utility model relates to a motor vehicle braking vertical rod for preventing brake shoe eccentric wear, which relates to a motor vehicle inner brake shoe connector, and solves the problem that brake shoe eccentric wear greatly affects driving safety. Including the vertical bar body, the vertical bar body is divided into an upper fixed end, a middle connecting end and a lower fixed end from top to bottom, the upper fixed end is provided with an upper fixed hole, the lower fixed end is provided with a lower fixed hole, and the upper fixed hole It is located on the same horizontal plane as the lower fixing hole in the radial direction, and the axes of the two holes are parallel to each other; there is a revocation hole for fixing the brake shoe support in the middle of the middle connection end, and the axis of the revocation hole is clamped with the axes of the upper and lower fixing holes. Angle, the angle is 3.8 degrees -5.7 degrees. The invention makes the angle change of the brake shoe compared with the prototype after installation, increases the curved contact area between the brake shoe and the tread surface of the wheel rim, and at the same time lowers the unilateral force state of the brake shoe to change the central force, eliminates the eccentric wear of the brake shoe, and makes the whole brake shoe bear the force , to avoid partial shedding of brake shoes after eccentric wear, and poor braking will endanger driving safety.

Description

technical field

[0001] The invention relates to an inner brake shoe connecting piece of a motor vehicle, in particular to a motor vehicle brake vertical rod for preventing eccentric wear of the brake shoe. Background technique

[0002] like figure 1 As shown, with the development of enterprise railway transportation at present, diesel locomotives are the main traction power of current railway transportation. During the transportation operation, due to the special operation of the enterprise, the transportation distance is short, and there are many reverse transportations. , Unluckily, the locomotive braking is abnormally frequent, resulting in abnormal wear of the locomotive brake shoes. At the same time, due to the design and structure of the original locomotive brake beam, when the brake shoes are in contact with the wheel rim tread curve, unilateral contact occurs, resulting in eccentric wear. Not only the brake shoes The consumption is large, and at the same time, the f...
