Abstract
The utility model relates to an electro-tricycle rear axle with a motor direct driving mechanism, which solves the problems that the prior electro-tricycle rear axle is unstably for driving and a chain is easy to drop off. The electro-tricycle rear axle comprises an axle tube, a rear axle, a semi axle and a differential gear; the electro-tricycle rear axle is characterized in that arc firm reinforcing ribs are respectively arranged at the upper part and the lower part of the axle tube corresponding to the differential gear; an output gear is arranged at the end part of the output axle of a motor; the output gear is meshed with the bull wheel of the differential gear; and the bull wheel and the drive gear of the differential gear are coaxially arranged on the semi axle. The electro-tricycle rear axle has the advantages that the motor is arranged on the rear axle tube to form a whole body with the rear axle, a chain driving mechanism is avoided, the driving mechanism is simplified, and the centre distance of a main axle is not changed under the driving condition, thereby, the device structure is stable, the rideability of the vehicle is improved, the whole device is simple to be installed and easy to be maintained, noise is not generated during the driving and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of electric tricycle rearmost axle.
Background technology
At present, the electric transportation tricycle rear axle that everybody knows all is installed in motor on the carriage frame, and with the back axle split, adopt the chain drive driving rear axle; Chain drive is under different operating mode such as installation, load, motion, and its transmission width between centers can produce bigger variation, thereby makes chain drive transmission instability easily take off chain, has influenced the service life of transmission device, will cause the generation of accidents such as overturning when serious.
Summary of the invention
Drive unstable problem of easily taking off chain in order to solve existing electric tricycle rearmost axle, the utility model provides a kind of electric tricycle rearmost axle with motor direct-drive mechanism.
The technical solution that realizes above-mentioned purpose is as follows:
Electric tricycle rearmost axle with motor direct-drive mechanism comprises bridge tube, trailing wheel, semiaxis and diff;
Describedly be respectively equipped with circular-arc firm reinforced rib with the cooresponding bridge tube of diff upper and lower, on the circular-arc firm reinforced rib on top, be provided with electrical motor, the output shaft end of electrical motor is provided with output gear, the engagement of the big gear wheel of output gear and diff, and big gear wheel is located on the semiaxis with the diff driving gear is same.
Useful technique effect of the present utility model is, motor is installed on the back axle bridge tube, form an integral body with back axle, saved chain drive, simplified transmission device, alignment of shafts distance is constant in the driving cycle, thereby make this apparatus structure stable, the rideability of vehicle improves, and whole in addition device simple installation should keep in repair.Transmission does not produce noise, has improved service life.
Description of drawings
