Abstract
The utility model relates to a component of an electric three-wheel vehicle, in particular to a rear shaft of an integral type electric three-wheel vehicle. The rear shaft of the integral type electric three-wheel vehicle comprises a rear shaft and a motor, wherein the rear shaft is provided with a gear box; a driving wheel is arranged in the gear box; the motor is provided with a motor shell and a power shaft; and a shell cover is arranged on the power shaft end of the motor shell. The rear shaft of the integral type electric three-wheel vehicle is characterized in that an open hole is formed in the input side of the gear box; the open hole is matched with the structure of the shell cover of the motor; the shell cover of the motor is arranged in the open hole; connection screw holes are formed around the open hole and the shell cover; the open hole and the shell cover are connected by screws; and the power shaft of the motor is connected with the driving wheel of the gear box. Due to such structure, the rear shaft of the integral type electric three-wheel vehicle has the advantages that accessories are saved more, the cost is decreased, the transmission link is reduced, the power loss is reduced as well and the structure is compact.
Description
Technical field
The utility model relates to the electro-tricycle parts, specifically relates to a kind of electro-tricycle rear axle, and it is particularly suitable for the kiln car.
Background technology
Electric car rear axle has gear case and motor, gear case has power input shaft, motor is placed on the gear case, the power take-off shaft of motor and the power input shaft of gear case are towards identical direction, has gear at power take-off shaft and power input shaft, the chain that has that connects these two gears, such three-wheel vehicle rear axle have cost height, waste accessory, the more shortcoming of transmission process medium power loss.A kind of electro-tricycle rear axle is arranged, it comprises rear axle body and motor, motor has power take-off shaft, the rear axle body has gear case, gear case has the power input shaft towards the outside, described power input shaft periphery has keyway, and the power take-off shaft of described motor has identical power input shaft and keyway at axis hole, and power input shaft inserts in the axis hole and connects.Such rear axle also has the shortcoming that waste original paper, structure are compact not, take up room.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, and a kind of integrated type electric three-wheel vehicle rear axle that more can reduce accessory, reduction cost, reduce the loss of transmittance process medium power is provided.
The purpose of this utility model is achieved in that integrated type electric three-wheel vehicle rear axle, it comprises rear axle and motor, rear axle has gear case, driving wheel is arranged in the gear case, motor has motor casing and dynamical axis, motor casing has cap at the power axle head, it is characterized in that: described gear case has open pore at input side, open pore is the structure of the cap of identical motor, in the open pore that the cap of motor is placed, around open pore is connected with cap, have connecting screw hole and connect the driving wheel of the dynamical axis connection teeth roller box of motor with screw.
The beneficial effects of the utility model are: the integrated type electric three-wheel vehicle rear axle of this spline structure has more to be saved accessory, reduced cost, reduces transmission link, reduces the advantage of power waste, compact conformation.
Description of drawings
Fig. 1 is the utility model integrated type electric three-wheel vehicle rear axle cross-sectional view.
Fig. 2 is the right elevation of the utility model gear case when not having mounted motor.
Fig. 3 is the rear axle cross-sectional view of the another kind of situation of the utility model.
Fig. 4 be the utility model Fig. 3 do not have mounted motor the time gear case right elevation.
Wherein: 1, rear axle 2, motor 3, gear case 4, dynamical axis 5, cap 6, driving wheel 7, motor casing 8, open pore.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, integrated type electric three-wheel vehicle rear axle, it comprises rear axle 1 and motor 2, rear axle 1 has gear case 3, driving wheel 6 is arranged in the gear case 3, motor 2 has motor casing 7 and dynamical axis 4, motor casing 7 has cap 5 at dynamical axis 4 ends, it is characterized in that: described gear case 3 has open pore 8 at input side, open pore 8 is structures of the cap 5 of identical motor, in the open pore 8 that the cap 5 of motor is placed, have connecting screw hole on every side and connect the driving wheel 6 of the dynamical axis 4 connection teeth roller boxs of motor 2 with screw what open pore 8 was connected with cap.
The utility model because the cap of motor directly is inserted in the open pore of gear case, further reduces parts, reduces the intermediate power transmission link, saves accessory, reduces cost, reduces power waste.
