Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 The structural diagram of a detachable half-shaft drive axle shown includes a power transmission structure a and a detachable half-shaft b; wherein the power transmission structure a includes power transmission components such as differentials and final reduction gears. Such as figure 2 A sectional view of a detachable half shaft shown, including upstream half shaft 1, axle housing 2, controller 3, battery pack 4, wiring harness 5, downstream half shaft 6, permanent magnet 7, winding coil 8, bearing 9, The upstream half shaft 1 is connected to the differential through a spline, and receives the power torque transmitted downstream through the differential, and the other end is connected to the inner surface of the circumference of the downstream half shaft 6 through the bearing 9 sleeved on it. Shaft 1 and downstream half shaft 6 are...

Abstract

The invention relates to a control method of a drive axle with a disconnectable half shaft. The drive axle with a disconnectable half shaft is mainly composed of an upstream half shaft, a downstream half shaft, a bearing, a permanent magnet and a winding coil. One end of the upstream half shaft is connected to the differential through a spline, the other end is connected to one end of the downstream half shaft through a bearing, the other end of the downstream half shaft is connected to the hub, and the torque is transmitted between the upstream half shaft and the corresponding downstream half shaft through electromagnetic force. The input current of the winding coil is controlled by the controller, and the current output from the controller to the coil is adjusted according to the accelerator pedal opening signal; the adjustment principle is: the larger the accelerator pedal opening, the greater the current, the greater the accelerator pedal opening The smaller the degree, the smaller the current. The invention realizes the controllable disconnection of the half shaft of the drive axle, and can automatically adjust the splitting and connection of the half shaft according to the working conditions of the whole vehicle. At the same time, due to the use of electromagnetic force, there is no contact wear, stable performance, and long service life. No need for regular maintenance, safe and reliable.

Description

technical field [0001] The invention relates to a control method of a drive axle capable of disconnecting a half shaft, and belongs 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 the lef...
