Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of retarder devices, and specifically relates to a downhill retarder device for road passenger transport safety. Background Technique
[0002] The main function of the downhill retarder is to reduce the vehicle speed and keep the vehicle stable, thereby avoiding brake failure caused by frequent use of brakes. The downhill retarder converts the kinetic energy of the vehicle when going downhill into heat energy to achieve the retardation function of the vehicle. This converted heat energy needs to be dissipated by the engine's cooling system. If the cooling capacity of the engine is insufficient, it will affect the braking function of the retarder. Therefore, a downhill retarder device for road passenger transport safety is proposed.
[0003] The existing Chinese utility model patent with the reference publication number of CN214929663U discloses a double-power transmission downhill retarder control device, which belongs to the technical field of connection of automotive power systems. In this technical solution, it includes an air storage tank, a three-position two-way foot valve, a brake switch, a signal switch converter, and two groups of cylinders. The three-position two-way foot valve is installed in the cab. The air inlet of the three-position two-way foot valve is communicated with the air storage tank, and the working port is communicated with the air inlets of the two cylinders through a three-way joint. An exhaust pipe is connected to the exhaust port of the three-position two-way foot valve. The brake switch and the signal switch converter are sequentially arranged on the connecting pipeline between the three-position two-way foot valve and the cylinders. The brake switch is connected to the vehicle central control system, and the signal switch converter is connected to the vehicle ABS system. The output ends of the two cylinders are respectively connected to a retarder actuator on the double-power transmission. This double-power transmission downhill retarder control device has simple pipeline connection and convenient user operation, and can maximize the braking efficiency of the downhill retarder.
[0004] Based on the retrieval of the above patent and the combination with the equipment in the existing technology, it is found that due to the fast speed of the vehicle when going downhill, the driver's reaction time is insufficient, increasing the danger during vehicle driving. And the internal parts of the retarder are constructed as a whole, which is not easy to disassemble and maintain later. The existence of these problems affects the use of the device.
