Abstract

The invention relates to a hydraulic coupling type retarder and belongs to the technical field of machine manufacturing. The hydraulic coupling type retarder comprises a speed reducer, a water pump, apneumatic mechanical piece type clutch, a mechanical speed increasing gear and a power shaft connecting the pneumatic mechanical piece type clutch with the mechanical speed increasing gear from headto tail. The speed reducer is connected with the pneumatic mechanical piece type clutch through a chain wheel. An electromagnetic air valve is arranged at the front end of the pneumatic mechanical piece type clutch, a belt wheel A is arranged at the upper end of the mechanical speed increasing gear, and a belt wheel C is arranged at the lower end of the water pump. The mechanical speed increasinggear is connected with the water pump through a triangular belt. The hydraulic coupling type retarder further comprises a heat dissipation system and a liquid loop system. The heat dissipation systemand the liquid loop system are in connection control through a two-position three-way water inlet electromagnetic valve. The hydraulic coupling type retarder has the advantages that operation and installation are simple, the manufacturing and use cost is low, use and installation are not limited by an automobile engine and a speed changing box, and the hydraulic coupling type retarder is suitablefor medium and heavy type heavy-duty lorries of different types.

Description

technical field [0001] The invention relates to a hydraulic coupling retarder, which belongs to the technical field of mechanical manufacturing. Background technique [0002] With the development of the automobile industry, the use of medium and heavy-duty trucks continues to increase, and traffic accidents caused by brake failure due to the heat decay of automobile brake friction pads occur frequently. The limitations of a single traditional braking method are becoming more and more serious. more obvious. New braking technology devices to ensure the safety of automobiles have become an urgent need for transportation. The eddy current retarder is not suitable for use on medium and heavy trucks due to its high heat generation, prone to combustion accidents, and long intervals between each use. The hydraulic retarder has high processing precision and high cost, and its use and installation are more restricted by the automobile gearbox. . Contents of the invention [0003...
