Abstract

The invention discloses an independent assembly type front retarder system and a control method, the independent assembly type front retarder system comprises an air source, a proportional control air valve, a retarder control valve, a retarder cavity, a heat dissipation module and a power module which are connected in sequence, and one end of the retarder control valve is connected with the proportional control air valve; the other end of the retarder control valve is connected with the retarder cavity and the heat dissipation module, and a loop is formed between the retarder control valve and the retarder cavity; and a loop is formed among the retarder control valve, the retarder cavity and the heat dissipation module. A gas source is taken from high-pressure gas, and the proportional control gas valve controls the output pressure through the duty ratio of an electric signal; the position of the valve element is adjusted through output pressure; and controlling the braking of the system. A user who does not need high starting ability can reduce the complexity of a whole vehicle transmission system by additionally installing the independent assembly type front retarder, and more economical choices are provided for the user.

Description

technical field [0001] The invention relates to the field of auxiliary braking systems, in particular to an independently assembled front retarder system and a control method. Background technique [0002] The hydraulic retarder is an auxiliary braking system. For vehicles that often drive in mountainous areas, hills and urban areas that require frequent braking, the auxiliary braking system can greatly improve the driving performance of the car, and can also significantly improve the Driving comfort, prolonging the service life of automobile transmission and braking system. Compared with the eddy current retarder, the advantage of the hydraulic retarder is that the operating temperature of the hydraulic retarder is lower than that of the electric eddy current retarder, the electromagnetic interference to the whole vehicle is small, and it is easier to drive than the whole vehicle. For safety, the braking torque is stronger. [0003] According to the different layout posit...
