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 invention relates to the technical field of vehicle retarders, in particular to a water medium hydraulic retarder capable of improving driving safety. The water medium hydraulic retarder comprises a barrel shell, a retarding working cavity is arranged in the barrel shell in a penetrating manner, a rotor assembly is arranged in the retarding working cavity, and stator assemblies are arranged at the two ends of the retarding working cavity. The water medium hydraulic retarder is characterized in that a water tank is arranged at the lower side of the retarding working cavity, a water inlet channel communicated in an opening and closing mode is arranged between the water tank and the retarding working cavity, and a water pump used for pumping water in the water tank into the retarding working cavity is arranged on the water inlet channel. By means of the water medium hydraulic retarder, the rotor assembly and the stator assemblies are arranged, the rotor assembly is connected with the transmission end of a vehicle gearbox, the rotor assembly drives water to rotate at a high speed to impact the stator assemblies, the stator assemblies react on the rotor assembly to achieve speed reduction, abrasion is extremely low, and the speed reduction effect is good.

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...
