Embodiment Construction

[0017] The present invention will be further described below with respect to accompanying drawing:

[0018] see figure 1 Shown is a preferred embodiment of the present invention, in the figure, the front axle (1) integrated with drive steering clutch and shift gear and the rear axle (2) integrated with drive clutch shift gear form the main body of the device of the present invention, shown in the figure, the front axle The motor controller (3) is connected to and controls the front axle driving motor (5), and the motor driving gear (16) of the front axle driving motor (5) is connected to the clutch shifting gear set (17), and the motor driving gear (16) ) sliding selection combination with it to realize shifting or combination and separation, so that the front axle clutch and shifting integrated differential (6) drives the double axle shaft (7) to rotate and the transmission hub (8) to generate rotation. The steering assembly (9) drives the wheel hubs (8) on both sides to rot...

Abstract

The invention discloses an application method of a four-wheel drive electric vehicle body. The application method of the four-wheel drive electric vehicle body is characterized by comprising a drive steering clutch and gear shifting integrated front axle, a drive clutch and gear shifting integrated rear axle, a front axle motor controller and a rear axle motor controller. The application method of the four-wheel drive electric vehicle body comprises the steps that the front axle motor controller is connected with the drive steering clutch and gear shifting integrated front axle; and the rear axle motor controller is connected with the drive clutch and gear shifting integrated rear axle. The four-wheel drive electric vehicle body can be singly and independently driven by the front axle or the rear axle; when the four-wheel drive electric vehicle body is driven by one driving axle, the driving of the other driving axle can be stopped and a driving motor for the driving axle is separated from a differential mechanism to realize an effect of saving electric energy; and the front axle and the rear axle can be also enabled to simultaneously drive to increase the vehicle power so that the passing performance of the vehicle under complicated road conditions are more excellent.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method for using a four-wheel drive electric vehicle body. Background technique [0002] Since the invention of electric vehicles, a separate rear axle drive has been used, and the front axle drive is even rarer. When the vehicle adopts real-time four-wheel drive, the low efficiency becomes a problem when the road conditions are good. When the road conditions are bad, single-axle drive It is easy to burn the motor. The present invention utilizes the driving technology of the independent distribution of the front axle and the rear axle, so that the front axle and the rear axle can be driven independently and at the same time, achieving the effect of high driving efficiency of a single axle on a road with good road conditions The four-wheel drive force of the case is sufficient to pass the good effect. [0003] The patent document with the publication number ZL2015206767286 pro...
