Brake device with bidirectional braking function and application method thereof

Abstract

The invention relates to a brake device with a bidirectional braking function and an application method thereof. The brake device comprises a brake disc, a one-way clutch and a ratchet wheel locking mechanism. The brake disc is of a circular structure. A first limiting groove and a second limiting groove stretching along the radial direction of the brake disc are formed in the inner ring wall of the brake disc, the center lines of the first limiting groove and the second limiting groove are overlapped and penetrate the center of circle of the brake disc, an arc-shaped chute stretching inward is formed in the inner ring wall of the brake disc, one end of the arc-shaped chute stretches into the first limiting groove, and the other end of the arc-shaped chute stretches into the second limiting groove. The brake device can switch a slipping state and a non-slipping state automatically and has an instant braking function.

Description

technical field [0001] The invention relates to the technical field of automobile pulley block testing equipment, in particular to a braking device with a bidirectional braking function and a use method thereof. Background technique [0002] With the continuous enrichment of automobile products and the explosion of the SUV market in recent years, the test of vehicle passability is becoming more and more common. At present, the pulley block test frame for testing vehicle passability and power performance has a simple structure and a single function. In order to realize the function of braking or releasing the brakes on the pulleys without the need for the vehicle to exit during the vehicle test process, it ensures the safety and efficiency of the test. sex. There is a need for a braking device that can automatically adjust the braking of a pulley block and the release of a rotating pulley block. [0003] At present, the domestic pulley block brake device for automobile pull...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic pulley block brake device for automobile pulley block test equipment needs to be tested manually after the test vehicle stops the test, which is inconvenient to use. Moreover, during the test process, for the test vehicle with insufficient power, the vehicle will slip, or even pulley. If the staff does not brake the pulley in time, it is easy to make the test vehicle slide, which will cause danger to the vehicle and the staff
