Abstract

The invention relates to a drive axle capable of disconnecting semi-axle and a control method thereof. The drive axle is mainly formed by an upstream semi-axle, a downstream semi-axle, a bearing, a permanent magnet and a winding coil. One end of the upstream semi-axle is connected with a differential mechanism by a spline, the other end is connected with one end of the downstream semi-axle by thebearing, the other end of the downstream semi-axle is connected with a hub, and torsion is transferred between the upstream semi-axle and the corresponding downstream semi-axle by electromagnetic force. Input current of the winding coil is controlled by a controller. The drive axle realizes controllable disconnection of the semi-axles of the drive axle, and can automatically adjust the disconnecting and connecting power of the semi-axles according to the working condition of the whole automobile, and meanwhile, by adopting a manner of electromagnetic acting force, contact abrasion is avoided,the performance is steady, the service life is long, aged-based maintenance is not needed, and the drive axle is safe and reliable.

Description

technical field [0001] The invention relates to a drive axle capable of disconnecting half shafts and a control method thereof, belonging to the technical field of vehicles. Background technique [0002] The drive axle is located at the end of the car transmission system and is mainly composed of the final drive, differential, half shaft and drive axle housing. The entire drive axle is connected to the frame through the suspension. The power of the engine is transmitted from the transmission shaft to the main reduction gear, and then transmitted to the half shafts at both ends through the differential, and then to the tires through the half shafts to drive the whole vehicle to run. During the process, the main reducer changes the direction of torque transmission through a pair of bevel gear pairs, and the speed ratio of the main reducer increases the torque of the engine while reducing the speed to meet the needs of the car. The differential can make the rotation speed of t...
