Motive power and fluid power driving device based on motor and torque converter integration unit

Abstract

The invention discloses a motive power and fluid power driving device based on a motor and torque converter integration unit. The motive power and fluid power driving device based on the motor and torque converter integration unit is characterized in that a front end cover of a motor and a housing of a fluid power torque converter are fixedly connected into a whole, one end of a fluid power torque converter pump wheel is connected with a rotating shaft of the motor through splines and a cover disk, the other end of the fluid power torque converter pump wheel is fixed on a flange plate shaft sleeve through splines on and a bearing and a pump wheel hub, a guide wheel is fixed on the flange plate shaft sleeve through splines, a flange plate is fixedly connected with a front cover of a torque converter through threads, a worm wheel is connected with an output shaft through splines and a worm wheel hub, and the motor can be an inner rotor motor or an external rotor motor. Compared with the prior art, a coupler is removed, the rotating shaft of the motor and the input shaft of the torque converter is the same shaft, and accordingly the problem that concentricity precision of two side shafts of the coupler is low is solved, impacts among connections are reduced, and furthermore the motive power and fluid power driving device based on the motor and torque converter integration unit is stable in running, low in noise, high in driving efficiency, compact in structure, and small in occupying space, and can replace a motor fluid power torque converter which can only use the coupler for integration.

Description

technical field [0001] The invention relates to a power hydraulic transmission device, in particular to a power hydraulic transmission device based on an integrated unit of a motor and a torque converter. Background technique [0002] At present, the connection between the hydraulic torque converter and the power unit mostly adopts an intermediate connection mechanism. For example, Chinese patent 90214052 discloses a hydraulic torque converter motor, which integrates the motor and the hydraulic torque converter through a coupling. Due to the problem of low concentricity accuracy of the shafts on both sides of the coupling, the motor of this torque converter vibrates greatly and the noise is large during operation; due to the coupling installed between the motor and the torque converter, The structure of the transmission system is huge and cannot be used in places with limited space; at the same time, due to the existence of the coupling, the transmission distance of forc...

Problems solved by technology

Due to the problem of low concentricity accuracy of the shafts on both sides of the coupling, the motor of this torque converter vibrates greatly and the noise is large during operation; due to the coupling installed between the motor and the torque converter, The structure of the transmission system is huge and cannot be used in places with limited space; at the same time, due to the existence of the coupling, the transmission distance of force or torque increases, which increases the mechanical loss of energy during transmission and reduces the transmission efficiency.
