Problems solved by technology

However, the differential lock is only used in bad road conditions or extreme conditions, and it will cause serious damage to car components when used in normal driving
It is troublesome to manually lock and unlock according to different road conditions, and it is easy to damage parts if the operation is wrong
Some advanced structures can realize automatic locking and unlocking, but passive frequent locking and unlocking will affect the service life and driving comfort
[0004] In addition, in the automobile structure of the independent drive structure in the prior art, the power of each wheel of the independent drive structure uses a motor (hub motor) embedded in the wheel, the power and speed ratio are limited, the bearing capacity is poor, the overall structure is complex, and the reliability is not good. high
Using 4 motors and drive modules, the number is large and the reliability is low, and the performance of each motor is often inconsistent. During the driving process, especially when going straight, it is necessary to measure the speed continuously to correct the speed difference between the motors on both sides, so as to keep the vehicle running straight and the driver to work. Strong, easily fatigued

Abstract

The invention discloses an automobile using novel axles. The automobile using the novel axles comprises the front axle connected with front wheels of the automobile, the rear axle connected with rear wheels, an engine and a main power output shaft. The engine is connected with an automobile chassis, and the engine is connected with the main power output shaft. The automobile further comprises a driving motor and an auxiliary power output shaft. The driving motor is connected with the front axle or the rear axle, and the main power of the engine is transmitted to a front axle differential which is connected with a front axle semi-shaft through the main power output shaft or to a rear axle differential which is connected with a rear axle semi-shaft. The power of the driving motor is transmitted to the front axle differential or the rear axle differential through the auxiliary power output shaft. The front wheels are connected with the front axle semi-shaft, the rear wheels are connected with the rear axle semi-shaft, and the front axle or the rear axle is an automobile active differential drive axle. The automobile using the novel axles can obtain a small turning radius, achieves good driving performance, has the good road surface adaptive capacity, possibility and flexibility, and achieves spinning in situ and turning around in narrow space.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile using a novel axle. Background technique [0002] The axle and differential structure adopted by the automobile in the prior art allows the half axles on both sides to rotate at different speeds while transmitting power to the half axles on both sides of the axle, so that the wheels on both sides can be unequaled in the form of pure rolling as much as possible. reduce the friction between the tire and the ground. However, in off-road or bad road conditions, due to the equal torque of the differential, the vehicle may get into trouble because any wheel loses adhesion. [0003] The axle with differential lock can lock the differential case and the half shaft together when one drive wheel slips, so that the differential loses its differential effect and transfers the torque to the drive shaft on the other side. be able to obtain sufficient driving force. However...
