Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 The schematic diagram of a new type of detachable half-shaft drive axle is shown, including the power transmission structure a, the detachable half-shaft b, and the hub c; the detachable half-shaft b also includes the upstream half-shaft 1 and the downstream half-shaft 2. The upstream half-shaft 1 is connected to the power transmission structure a, and the downstream half-shaft 2 is connected to the hub c; wherein the power transmission structure a includes power transmission components such as differentials and main reduction gears.

[0034] Such as figure 2 A sectional view of a detachable half shaft shown, including the upstream half shaft 1, the axle housing 6, the downstream half shaft 2, the permanent magnet 4, the winding coil 3, the bearing 5 and the controller 7, and the upstream half shaft 1 passes through the spline It is...

Abstract

The invention relates to a novel drive axle capable of disconnecting half axles and a control method thereof. The novel drive axle is mainly composed of an upstream half axle, a downstream half axle,a bearing, a permanent magnet, a winding coil and an axle housing. One end of the upstream half axle is connected with a differential mechanism by virtue of a spline, and the other end of the upstreamhalf axle is opposite to one end of the downstream half axle and is fixed on the axle housing by virtue of the bearing; the one end of the downstream half axle is also fixed on the axle housing by virtue of a bearing, and the other end of the downstream half axle is connected with a hub; twisting force is transferred by electromagnetic force between the upstream half axle and the corresponding downstream half axle; and input current of the winding coil is controlled by a controller. Controllable disconnection of the half axles of the drive axle is realized, and separation and combination andconnection strength of the half axles can be automatically adjusted according to complete vehicle conditions. Meanwhile, since a manner of electromagnetic interaction force is adopted, the novel driveaxle does not have contact wear, is stable in performance, long in life, safe and reliable and does not need age-based maintenance.

Description

technical field [0001] The invention relates to a novel 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 spee...
