The invention discloses a parallel type hybrid power vehicle power coupling device. The parallel type hybrid power vehicle power coupling device comprises a coupling device input shaft, a coupling device output shaft and a power coupling and detaching mechanism. The power coupling and detaching mechanism comprises a torque limiting clutch, a one-way clutch and a rotor splined hub. The torque limiting clutch is arranged in an inner ring of a motor rotor. The inner ring of the torque limiting clutch is connected with one end of the coupling device input shaft. A groove is arranged in the end of the coupling device input shaft. The one-way clutch is arranged inside the groove. The inner ring of the one-way clutch is connected with the coupling device output shaft. The motor rotor is connected with the coupling device output shaft through the rotor splined hub in the inner ring of the motor rotor. With the adoption of the structure, all main components of the power coupling device are arranged in the inner ring space of the motor rotor, so that the structure of axial coinciding and radial nesting is achieved, axial size of the coupling system is reduced, the defects that the parallel type hybrid power vehicle parallel coupling system has large assembly size and axial dimension are overcome.
Description
technical field [0001] The invention relates to the technical field of hybrid electric vehicle transmission, in particular to a parallel hybrid electric vehicle power coupling device. Background technique [0002] Existing hybrid vehicles can be divided into series hybrid systems, parallel hybrid systems and hybrid hybrid systems according to the energy transmission routes of engines and electric motors. The principle of the series hybrid power system is simple, but the layout space is large and the weight is heavy. At the same time, the system has high performance requirements for the efficiency of the battery system and the motor system, and the energy loss of the entire system in the transmission path is large, so it is rarely used now; Hybrid system, the principle and structure are complex, and the system performance mainly depends on the control strategy and precision of the control system, the control is complex and the technical requirements are high; the parallel hyb...
