Problems solved by technology
The retarding auxiliary braking device often has the problem of engagement and disengagement lag and long response time, and its braking effect is not ideal
[0004] In the environment where electric vehicles have become the future development trend, because the drive train of electric vehicles is becoming simpler and has no engine and gearbox, the traditional retarder is no longer applicable

The present disclosure relates to a retarder auxiliary braking system and a vehicle. The retarder auxiliary braking system includes: a hydraulic coupling including a casing, a first turbine, a second turbine, a first shaft and a second shaft, and the first turbine The second turbine is arranged in the casing opposite to the first turbine, the first turbine is fixed to the first shaft, the first shaft is connected to the final drive through the transmission mechanism, the second turbine is fixed to the second shaft, and the second shaft is fixed to the axle housing; The oil control circuit includes an oil circuit and a pneumatic circuit, the oil circuit includes a fuel tank, an oil supply pipeline and an oil return pipeline, and the pneumatic circuit includes an air source device and a first air supply pipeline; and, the control unit, and the air source device Connected, the control unit controls the work of the air source device to adjust the pressure and volume of the oil in the housing. Through the above technical solution, the retarder auxiliary braking system provided by the present disclosure can not only respond to braking sensitively and quickly and provide braking performance, but also reduce the impact on the layout of the whole vehicle, and is suitable for electric vehicles.
Description
technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a retarding auxiliary braking system and a vehicle. Background technique [0002] During the driving process of the vehicle, if the driver often needs to step on the brake pedal frequently, the brake shoes and the brake drum will rub frequently, resulting in increased wear and tear, which can easily lead to the braking failure of the vehicle's braking system and cause traffic. ACCIDENT. [0003] In the prior art, a slow-speed auxiliary braking device is provided in the vehicle, and the slow-speed auxiliary braking device requires a gearbox to be matched with it, which not only affects the layout of the whole vehicle, but also affects the rear suspension of the engine, and the reliability and lower durability. For example, in some vehicles, a hydraulic coupling is used in the retarding auxiliary braking device, and the gearbox and the hydraulic coupling are connec...
