Hydraulic motor integrated transmission device

Abstract

The invention relates to a hydraulic motor integrated transmission device, which comprises a machine base, an outer rotor motor and a hydraulic coupler and is characterized in that the machine base is composed of a machine base end cover and a machine base casing, the outer rotor motor and the hydraulic coupler are installed in the machine base, pump impeller blades of the hydraulic coupler are directly and fixedly connected with outer rotors of the outer rotor motor, an inner stator shaft of the outer rotor motor is concentric with an output shaft of the hydraulic coupler, the shaft end of the inner stator shaft of the outer rotor motor is fixed on the machine base casing, and the output shaft of the hydraulic coupler extends out of the machine base end cover. The hydraulic motor integrated transmission device has the advantages of being capable of absorbing impact and vibration brought by outer load, being so good in overload protection performance that a power source can still rotate without being damaged even when the output shaft is clamped, and being good in loaded start-up performance and power performance and capable of achieving automatic speed changing.

Description

technical field [0001] The invention belongs to the field of electromechanical integrated power transmission devices, in particular to a hydraulic motor integrated transmission device based on an outer rotor motor and a hydraulic coupling. Background technique [0002] The motor and hydraulic transmission are usually two independent entities connected by flanges and couplings. The hydraulic torque converter motor with the patent No. 90214192.9 connects the motor and the hydraulic element with a coupling, and the output end of the hydraulic element is used as the output of the whole integrated device. This patent is limited to the axial arrangement of the motor and the hydraulic components, and has not achieved a high degree of integration of the two, so the volume is relatively large, and it cannot solve the problem that the two transmission shafts of the motor and the coupler are difficult to be concentric. At the same time, during the energy transfer process The mechanica...

Problems solved by technology

[0005] The invention has the advantages that the motor and the hydraulic element are highly integrated, which solves the problem that the two drive shafts of the motor and the coupler are difficult to be concentric, and at the same time reduces the mechanical loss in the energy transmission process, improves the transmission efficiency, increases the The transmission is stable and the noise is reduced. Compared with the inner rotor, the outer rotor motor has a larger output torque, so it can provide a larger starting torque for the system; the high integration of the motor and hydraulic components can Increase the specific power of the transmission device, make the structure compact, reduce the volume and reduce the cost, especially the shock and vibration caused by the external load can be absorbed, the overload protection is good, and the power source can still run even when the output shaft is stuck. No damage, good start-up performance with load, can realize automatic shifting, good power performance of the transmission device
