Embodiment Construction
[0024] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. In order to provide a comprehensive understanding of the present invention, many details are described below, but it will be apparent to those skilled in the art that the present invention can be practiced without these details. Known components, methods and processes will not be described in detail below.
[0025] A wheel drive system with transmission, refer to figure 1 , including four driving wheels 1 and four driving mechanisms, the four driving wheels 1 are symmetrically arranged on the front, rear, left and right sides of the vehicle chassis, each driving wheel 1 is correspondingly provided with a driving mechanism, and each driving mechanism Comprising a driving motor 21 and a transmission 22, the output end of the driving motor 21 is mechanically connected to the driving wheel 1 through the transmission 22, the driving motor transmits power to the...

The invention provides a wheel-side drive vehicle with a transmission and a control method thereof. The wheel-side drive vehicle with a transmission comprises four drive mechanisms and four drive wheels, each drive mechanism comprises a drive motor and the transmission, the transmission has a gear shifting and speed changing function, and the drive motor transmits power to the drive wheels throughthe transmission so as to drive the vehicle to run. Through coordination and independent control of the four drive systems, switching of various drive models can be achieved, and driving under various working conditions can be met. In a snowfield mode, the torque output of the motor can be effectively adjusted, and the driving operation safety is improved; in the normal mode, on the premise thatthe dynamic property of the whole vehicle is met, the optimal economy of the whole vehicle can be achieved through switching of the motor state and the transmission gear; through the torque distribution design of the four drive systems, the operation stability of the whole vehicle can be improved; unpowered interruption gear shifting can be achieved, and the smoothness of a vehicle is improved.
Description
technical field [0001] The invention relates to the technical field of automobile drive systems, more specifically, a wheel-side drive system with a transmission and a control method thereof. Background technique [0002] At present, there are two main types of four-wheel drive vehicles on the market: one is wheel-drive vehicles, which adopt electronic differential speed; Among them, the wheel drive vehicles all adopt the drive motor matching reducer scheme, the matching adaptability of the system is not high, the working mode is relatively single, and the best match between the power and economy of the vehicle cannot be achieved; while the front and rear axles adopt the central direct drive structure For the type of vehicle, because the differential speed is realized through the differential, the left and right wheel torque cannot be independently distributed, which is not conducive to the improvement of the vehicle's handling stability. In addition, on low-adhesion road s...
