Description
Technical field
The utility model relates to a kind of electro-tricycle power drive, especially a kind of power drive of electric tricycle rearmost axle.
Background technology
The power drive of current electric tricycle rearmost axle, great majority are structure as shown in Figure 1, comprise the back axle assembly with differential bag, differential bag is connected with one end of transmission shaft by universal device, and the other end of transmission shaft is connected with motor by another universal device.Such structure be used for reference motorcycle rear axle power drive and come, but there is following techno-absence in it:
1, because its differential bag is connected with motor with transmission shaft by universal device, universal like this device and transmission shaft certainly will want distribute torque, the loss of moment of torsion will be there is;
2, because universal device and transmission shaft can produce vibration and noise in operational process, vibration can shorten the service life of universal device and transmission shaft, and noise can allow user not feel well;
3, because universal device belongs to easily-consumed products, use a period of time just to need to change, waste time and energy, virtually add cost;
4, such power drive is mounted in bottom electro-tricycle frame, keeps in repair cumbersome.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of power drive without loss of torque, friction, noiselessness, cost reduction, electric tricycle rearmost axle easy to maintenance.
The utility model solves the technical scheme that its technical matters adopts: a kind of power drive of electric tricycle rearmost axle, comprise back axle assembly, differential bag and motor, also comprise planetary reduction gear box, described planetary reduction gear box is between differential bag and motor, described differential bag has input shaft, the input shaft of differential bag is connected with the output shaft of motor, and the shell of differential bag is connected with the housing flange of star reducing gearbox.
Further, described back axle assembly comprises hind axle and left and right pipe spreader, and described differential bag is installed on the medium position of hind axle, the both sides Flange joint of left and right pipe spreader and differential bag.
Further, described planetary reduction gear box comprises the flange being positioned at its front end, the pinion carrier coordinated with flange, gear ring, four planetary wheels being positioned at gear ring and a sun gear, and the output shaft of described motor passes the axis hole of sun gear.When planetary number is less than four, planetary wheel is easily damaged under driven by motor; When planetary number is greater than four, motor cannot provide enough tractive forces.
The beneficial effects of the utility model are: the utility model eliminates universal device and transmission shaft, and almost without loss of torque, also friction and noise, also reduce cost; Add four planetary reduction gear boxs between differential bag and motor, and by Flange joint, without the need to other driving device and stent support, installation, maintenance is convenient; Can lubricating oil be added in planetary reduction gear box, greatly increase its service life.
