Abstract
The utility model discloses a transmission device of an electric vehicle, which comprises a motor and a back axle; a tooth-shaped chain wheel and a tooth-shaped chain are used for the transmission between the motor and the back axle, a differential mechanism is arranged on the back axle, and the tooth-shaped chain wheels are respectively arranged on an output shaft of the motor and an input shaft of the differential mechanism; the motor is positioned above the differential mechanism, and the tooth-shaped chain wheel and the tooth-shaped chain are coated in a casing body. The utility model has the advantages of high transmission efficiency, low noise, steady turning and good reliability.
Description
The utility model relates to a kind of driving device of vehicle.
At present, the domestic driving device that is used for elec. vehicle all adopts roller chain or drop-gear box, and the shortcoming of these two kinds of type of drive is: driving efficiency is low, noise is big, and automobile differential is not installed, cause Vehicular turn not steadily, poor reliability.
The purpose of this utility model is: a kind of driving device of elec. vehicle is provided, and this device not only is equipped with diff, has also adopted the type of drive of gear and silent chain, and driving efficiency height, noise be little, turn to steadily, good reliability.
The technical solution of the utility model is: a kind of driving device of elec. vehicle, comprise motor, back axle, and adopt profile of tooth sprocket wheel and silent chain transmission between described motor and the back axle.
The further technical scheme of the utility model is: a kind of driving device of elec. vehicle, comprise motor, back axle, and adopt profile of tooth sprocket wheel and silent chain transmission between described motor and the back axle; On the described back axle diff is installed, the profile of tooth sprocket wheel is installed in respectively on the input shaft of the output shaft of motor and diff.
The more detailed technical scheme of the utility model is: a kind of driving device of elec. vehicle, comprise motor, back axle, and adopt profile of tooth sprocket wheel and silent chain transmission between described motor and the back axle; On the described back axle diff is installed, the profile of tooth sprocket wheel is installed in respectively on the input shaft of the output shaft of motor and diff; Described motor is positioned at the top of diff, and in shell, motor is fixed on the shell by envelope for profile of tooth sprocket wheel and silent chain, and shell is fixed on the back axle.
The utility model has the advantages that:
1. the utility model is equipped with diff on the back axle of elec. vehicle, makes Vehicular turn steady, good reliability.
2. the utility model has adopted the type of drive of profile of tooth sprocket wheel and silent chain, and the driving efficiency height, driving torque is big, noise is low.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a shape assumption diagram of the present utility model;
Wherein: 1 motor; 2 back axles; 3 difies; 4 output shafts; 5 input shafts; 6 profile of tooth sprocket wheels; 7 silent chains; 8 shells.
