Brake with limit device

Abstract

The invention discloses a brake with a limit device. The brake is characterized in that the brake with the limit device comprises a brake shell and a braking pull arm, a reversed U-shaped limit support is arranged on the brake shell, and a movable limit screw is arranged on the limit support. The brake with the limit device has the advantages that a user can adjust the position of the limit screw freely, the braking gap is greatly reduced, and the brake is convenient and fast to adjust, perfectly matches with vehicles of different types and is wide in application range. Due to the fact that the braking gap is removed, the braking impact force between the limit support and a braking lingual plate is greatly lowered, the service life of a damper and the brake is greatly prolonged, the braking distance of an electric vehicle can be shortened by 0.2-0.5 m, and the safety performance of the electric vehicle is greatly improved.

Description

technical field [0001] The invention relates to a vehicle brake, more precisely, a vehicle brake with a limiting device. Background technique [0002] Existing brakes, especially electric vehicle brakes, mainly perform braking through the cooperation of a pair of brake shoes. During the installation of the brake, a tongue-shaped brake tongue on the shock absorber of the electric vehicle needs to cooperate with a limit bracket on the brake housing of the brake. Due to the variety of electric vehicle models, the cooperation between the brake tongue plate and the limit bracket cannot be guaranteed to be perfect, resulting in a large braking gap between the brake tongue plate and the limit bracket. During the braking process of the electric vehicle, the braking gap will cause a violent braking impact force between the limit bracket and the brake tongue, causing damage to the shock absorber itself. At the same time, if the braking gap is too large, the braking distance will be ...

AI Technical Summary

Problems solved by technology

Due to the variety of electric vehicle models, the cooperation between the brake tongue plate and the limit bracket cannot be guaranteed to be perfect, resulting in a large braking gap between the brake tongue plate and the limit bracket

During the braking process of the electric vehicle, the brake gap will cause a violent braking impact force between the limit bracket and the brake tongue, causing damage to the shock absorber itself

At the same time, if the braking clearance is too large, the braking distance will be too long, the braking effect will be poor, and it will easily cause traffic accidents.
