Hydraulic braking system of light multi-section connecting trailer

Abstract

The invention relates to a hydraulic braking system of a light multi-section connecting trailer. A tractor, a normal trailing carriage, a trailing carriage with a vacuum power braking device and a traction seat are included; the tractor is connected with the normal trailing carriage, the trailing carriage with the vacuum power braking device is connected with the normal trailing carriage through the traction seat; the tractor is provided with a braking pedal assembly, a vacuum power braking pump assembly, a tractor output braking cable, tractor front and rear bridges, a braking pipeline and the tractor seat. The system has the advantages that the braking force of the pedal of the tractor is transmitted to the tractor and multiple trailing carriages through the braking cable to simplify thebraking system of the trailing carriages, the synchronous braking of the tractor and the trailing carriages is ensured, the trailing carriages are provided with an independent braking function, real-time braking is achieved, and the purposes of simplifying the braking system, ensuring the braking performance of the system and reducing the production cost are achieved.

Description

technical field [0001] The invention relates to a hydraulic braking system for a light-duty multi-joint trailer. Background technique [0002] At present, the hydraulic braking system used by the existing light-duty multi-joint trailers mostly adopts the mode of independent braking of the tractor. There is no corresponding integrated braking mechanism in the subsequent series of cars, and some of them are equipped with cooperative brakes. The braking mechanism of the light-duty multi-joint trailer is relatively complicated and inconvenient to operate. Therefore, it is necessary to provide a braking system with simple operation and simple structure, so that the light-duty multi-joint trailer can be braked more easily. Simple and effective. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a hydraulic braking system for a light-duty multi-joint trailer, the hydraulic braking system for a light-duty multi-joint ...
