Further, the hydraulic pressure torsion buffering connection structure has further included a clutch friction disk component, the clutch friction disk
Component includes fixed friction disk and sliding friction disk, and fixed friction disk is fixedly installed in hydraulic pressure power twister housing and the second axis
On the end face of hole homonymy, sliding friction disk is by spline package on driving box input shaft and cloth opposite with fixed friction disk
It puts, there are gaps between fixed friction disk and sliding friction disk.
Compared with prior art, the present invention advantage is：
The buffer of the present invention is applied between the motor of electric vehicle and driving box input shaft, using hydraulic pressure torsion and
The combination kind of drive of clutch friction disk forms non-rigid connection in the electric motor starting starting stage, can alleviate starting moment
Speed discrepancy ensures that starting is steady, and can alleviate the stall phenomenon for reducing big resistance startup situation, protects motor, reduces consumption
Electricity and overheat extend the service life of motor；And frictional disk can be utilized to form direct-drive after certain rotating speed is reached and connected,
Ensure normally travel.
In order to the clearer specific embodiment party for understanding the present invention, the present invention being elaborated below with reference to description of the drawings
Formula.
Description of the drawings
Fig. 1 is local interior's structure diagram of the present invention.
Specific embodiment
As shown in Figure 1, motor rear axle of the present invention with motor drive buffer, include drive connection motor and
Driving box input shaft is provided between the output shaft 1 of the motor and driving box input shaft 2 and is driven by Motor torque
Dynamic hydraulic pressure torsion buffering connection structure 3 so that motor forms non-between startup starting stage and driving box input shaft
Rigid connection.
Above-mentioned hydraulic pressure torsion buffering connection structure 3 includes a hydraulic pressure power twister housing 31 and the turbine in housing
32nd, pump impeller 33 and oil body (not shown), wherein：The generally oval structure of hydraulic pressure power twister housing 31, opposite end
Shell position offers the first axis hole and the second axis hole；The turbine 32 is located at side in housing 31, and shaft core position is worn with activity
1 end of motor output shaft for crossing the first axis hole of housing is fastenedly connected；The pump impeller 33 is located at opposite side in housing 31, shaft core position
2 end of driving box input shaft for passing through the second axis hole of housing with activity is fastenedly connected；Full 1 inside of housing of oil body filling is empty
Between.
As advanced optimizing for above-mentioned technical proposal, the hydraulic pressure torsion buffering connection structure has further included a clutch and has rubbed
Disk component is wiped, which includes fixed friction disk 34 and sliding friction disk 35, and fixed friction disk 34 is set to
In hydraulic pressure power twister housing on the end face of the second axis hole homonymy, sliding friction disk 35 by spline package in driving box input pass
On moving axis 2 and positioned opposite with fixed friction disk 34, there are gaps between fixed friction disk 34 and sliding friction disk 35.
