Problems solved by technology

[0004] However, the existing water-medium hydraulic retarders also have fatal shortcomings. Water is very easy to evaporate, and it is easy to generate a large steam pressure when the retarder is working. It is necessary to control the working pressure well and cool down in time. The requirements for the working environment High, the loss of water is very large during pressure relief, and it needs to be replenished from time to time, which is troublesome; and the lag time of engagement and separation is long, and there is power loss when not working, which increases the burden on the engine

Abstract

The present invention relates to the technical field of vehicle retarders, in particular, to an aqueous medium hydraulic retarder for improving driving safety, which includes a cylinder shell, and a retarder working chamber is provided through the cylinder shell, and the retarder A rotor assembly is provided in the slow-speed working chamber, and a stator assembly is provided at both ends of the slow-speed working chamber. An open and closed water inlet is provided between them, and a water pump for pumping the water in the water tank into the slow-speed working chamber is arranged on the water inlet. The invention arranges a rotor assembly and a stator assembly, the rotor assembly is connected to the transmission end of the vehicle gearbox, the rotor assembly drives water to rotate at high speed and impacts the stator assembly, and the stator assembly reacts on the rotor assembly to achieve deceleration, with extremely low wear and good deceleration effect.

Description

technical field [0001] The invention relates to the technical field of vehicle retarders, in particular to an aqueous medium hydraulic retarder for improving driving safety. Background technique [0002] For cars that often travel in mountainous or hilly areas, in order to continuously reduce or maintain a stable vehicle speed for a long time when going down a long slope and reduce or release the load on the service brake, it is usually necessary to install auxiliary braking devices such as retarders. Depending on the working principle, automotive retarders can be divided into typical structural forms such as engine retarders, hydraulic retarders, electric turbine retarders, motor retarders, and aerodynamic retarders. [0003] Among them, the hydraulic retarder stands out for its high retarding performance, small size and quality, and no wear and tear during work. Among them, the water medium hydraulic retarder has the best overall effect. As a medium, it has fast heat tran...
