Problems solved by technology

[0003] In order to ensure the driving safety of the vehicle, it is necessary to install a braking device on the vehicle, so the braking device for the trailer is an important auto part. In the existing braking devices for the trailer, the general trailer There is no service brake, that is, the brake device used for trailers is also a link-type brake mechanism. The connecting parts of the link-type brake mechanism are connected by pins, the connection gap cannot be eliminated, the brake response is not sensitive, and the braking effect is low. Poor, the connecting rod structure is more complex, takes up a lot of space, and the layout is inconvenient; when reversing, the driver needs to get out of the car to lock the reversing linkage mechanism. After the reversing is completed, the driver gets off again to release the reversing lock, which is very troublesome to use; And there is no disengagement of emergency braking, which is prone to danger

Abstract

The invention relates to a braking device applied to a full trailer. The braking device comprises a proportion-magnification hydraulic cylinder (6), a hydraulic braking device (10) and an electromagnetic hydraulic valve (9), wherein the proportion-magnification hydraulic cylinder (6) is in contact connection with a drag rod (1), the hydraulic braking device (10) is arranged on the full trailer, the electromagnetic hydraulic valve (9) is arranged between an output end opening of the proportion-magnification hydraulic cylinder (6) and an input end opening of the hydraulic braking device (10), a control end of the electromagnetic hydraulic valve (9) is connected with a drag rod signal controller, and the electromagnetic hydraulic valve (9) is designed to be a normally opening valve body. According to the braking device applied to the full trailer, which is disclosed by the invention, high-pressure liquid generated by triggering the proportion-magnification hydraulic cylinder (6) is utilized as a braking force, and a link-type braking mechanism is not utilized, so that the braking effect is good.
