Background
At present, automobiles with front-mounted engines (motors) are mainly divided into two types, one is front-mounted front-wheel drive of the engines (motors), and the other is front-mounted rear-wheel drive of the engines (motors). The automobile with the front-mounted engine (motor) and the front-mounted front-wheel drive has the advantages of high obstacle crossing capability, compact power assembly structure, convenience in improving riding comfort and the like.
In the front-drive automobile, the front axle is not only a steering axle but also a driving axle. For the automobile with the front axle adopting the front drive and the independent suspension, the power transmitted to the wheel side by the motor through the reduction gearbox needs to be transferred by a universal coupling. The universal coupling and the wheel rim of the wheel are designed separately according to the transmission design and are connected through a flange plate. Thus, a process is added in the assembly, and due to the separate design and model selection, the outer rotation center of the universal joint is difficult to be superposed with the virtual steering center line (main pin line) when the front wheels are steered. If the outer rotation center of the universal coupling and the virtual steering center line (main pin line) when the front wheel steers do not coincide, the length of the universal coupling changes in the steering process, the spline connecting the two parts of the universal coupling is abraded for a long time, and abnormal sound is generated at the position.
