Background
With the development of the times, the social demand for new energy and new technology is becoming stronger, and new energy products are more and more preferentially selected in both actual consumer markets and industrial policies. In view of this, the demand for electric drive technology in the field of motorcycles is also increasing.
In practical use, four-wheel motorcycles mostly need to walk on rough roads such as sand beaches, steps and the like, so that four-wheel drive is needed to improve the ground gripping capability to ensure better driving effect, and two-wheel drive can be adopted to improve the speed on normal walking roads.
Therefore, it is necessary to design a driving device for electric driving, which can be switched between four-wheel driving and two-wheel driving.

By adopting the technical scheme, the motor provides rotating speed and power for the front axle and the rear axle. The converter is used to switch the power of the motor between the front axle and the rear axle so that a rear-drive two-drive or a front-drive four-drive can be realized. When the converter outputs the rotating speed to the front axle, the rotating speed is output through a front driving transmission shaft.
Furthermore, the output end of the motor is a bevel gear, the input end of the converter is a basin gear meshed with the bevel gear, the basin gear is rotatably arranged in the shell of the converter and is sleeved on the conversion transmission shaft in a hollow way, the rear end of the conversion transmission shaft is connected to a differential gear in the rear axle, the front end of the conversion transmission shaft is connected to the rear end of a spline shaft through a bearing, the spline shaft is rotatably connected with a shell of the converter, the front end of the spline shaft is connected to the front drive transmission shaft, a conversion clutch is arranged between the spline shaft and the basin gear, the conversion clutch is connected to the conversion transmission shaft through a spline and can slide back and forth on the conversion transmission shaft, and the changeover clutch is selectively combined with the spline shaft or the basin gear or combined with the spline shaft and the basin gear simultaneously.
The rotating speed of the motor is output to the basin gear through the bevel gear, and the basin gear rotates. When the rear-drive two-wheel drive is adopted, the conversion clutch slides backwards to be combined with the bevel gear, the bevel gear drives the conversion transmission shaft to rotate through the conversion clutch, and the conversion transmission shaft transmits the rotating speed to the differential mechanism in the rear axle. When the four-wheel drive is adopted, the conversion clutch is simultaneously combined with the spline shaft and the basin gear, the basin gear drives the conversion transmission shaft to rotate through the conversion clutch, the conversion transmission shaft simultaneously transmits the rotating speed to the rear axle and transmits the rotating speed to the front axle through the spline shaft and the front drive transmission shaft. When the conversion clutch slides forwards and only is combined with the spline shaft, the conversion clutch is separated from the basin gear at the moment, the input of the rotating speed is lost, and the gear is neutral.
Furthermore, an external spline is integrally formed on the outer circumference of the conversion clutch, and internal teeth meshed with the external spline of the conversion clutch are arranged in the spline shaft and the basin gear.
The conversion clutch is connected with the spline shaft and the basin gear in a spline mode, so that the stability and the reliability are better in practical use, and the switching is convenient.
Furthermore, a shifting fork groove is formed in the middle of the conversion clutch.
The arrangement of the shifting fork groove is used for being matched with another shifting fork, and the conversion clutch is reliably shifted to and fro on the transmission shaft.
Further, the output shaft of the motor transmits the rotation speed to the bevel gear through a reduction gear set.
The direct output rotating speed of the motor is high, and the required rotating speed can be obtained after the speed is reduced through the reduction gear set.
Has the advantages that: the invention has novel concept, reasonable design and easy operation, effectively realizes the conversion of rear-drive two-wheel drive and simultaneous driving of front wheels and rear wheels based on the motor as a power source, and has stable operation, smooth action and good effect in the whole switching process.

An external spline is integrally formed on the outer circumference of the conversion clutch 4d, and internal teeth meshed with the external spline of the conversion clutch 4d are arranged in the spline shaft 4c and the basin gear 4 a. The middle of the changeover clutch 4d is provided with a shift fork groove 4 da. The rotating shaft of the motor 1 transmits the rotation speed to the bevel gear 1a through a reduction gear set.
In particular embodiments, electric motor 1 provides rotational speed and power to front axle 5 and rear axle 3. The converter 4 is used to switch the power of the electric motor 1 between the front axle 5 and the rear axle 3 so that a rear-drive two-drive or a front-drive four-drive can be realized.
