The invention relates to the technical field of vehicle auxiliary brake, in particular to a connecting structure of a transmission and a parallel hydrodynamic retarder; and the connecting structure is arranged on an output shaft of the transmission. The connecting structure comprises a driving gear coating the output shaft of the transmission, a driven gear fixedly arranged on an input shaft of the parallel hydrodynamic retarder and normally engaged with the driving gear, a synchronizer slidingly connected with the output shaft, and a drive for driving the synchronizer to perform the reciprocating slide corresponding to the output shaft and enabling the synchronizer to be combined with or separated from the driving gear. The structure can form or separate the power transfer between the output shaft of the transmission and the driving gear, so that the power transfer can be formed or separated between the output shaft of the transmission and the parallel hydrodynamic retarder, the working actuation of the parallel hydrodynamic retarder can be selected according to actual use demands, the energy consumption is reduced, and the service life is prolonged.
Description
Technical field [0001] The invention relates to the technical field of vehicle auxiliary braking, in particular to a connection structure of a transmission and a parallel hydraulic retarder. Background technique [0002] In order to improve the driving safety of vehicles, especially dangerous goods transport vehicles and long-distance buses, the vehicles are equipped with hydraulic retarders on long downhill sections. However, in the parallel hydraulic retarder connecting device for existing vehicles, the transmission output shaft driving gear and the transmission output shaft are fixed together to form a rigid body, that is, the input shaft of the hydraulic retarder and the connected The rotor is always in rotation. When the speed of the downhill in neutral gear is high and the speed of the input shaft of the hydraulic retarder exceeds the critical speed, it is easy to cause damage to the internal bearing of the hydraulic retarder, oil seal leakage and unnecessary energy consum...
