Drive Shaft A2133309902 For Mercedes W213

There are some differences in the design and working principle between the front drive axle, the rear drive axle and the four-wheel drive axle, as follows:

1. Front drive: The half axle of the front drive is usually directly connected to the transmission shaft of the front wheel, and the power is transmitted through the CV joint. The semi-axle of the front drive vehicle is mainly responsible for transmitting the power generated by the engine to the front wheels and driving the vehicle forward. Because the front wheel has the function of steering and driving at the same time, the semi-axle of the front drive vehicle needs to have high strength and durability.

2. Rear-wheel drive: The half shaft of the rear-wheel drive is usually connected to the transmission shaft of the rear wheel, and the power is transmitted through the traditional universal joint. The semi-axle of the rear-wheel drive is mainly responsible for transmitting the power generated by the engine to the rear wheel and driving the vehicle to retreat. The design of the rear-drive axle is relatively simple, but it needs to bear large torque and load.

3. Four-wheel drive: The axle of four-wheel drive usually includes two groups of axle shafts, which are connected to the drive shafts of the front and rear wheels respectively. The semi-axle of the four-wheel drive distributes the power to the four wheels through the central differential and the front and rear differential to realize four-wheel drive. The semi-axle of four-wheel drive needs to have higher strength and durability to cope with more complicated working environment and road conditions.

Generally speaking, there are some differences in the connection mode, transmission principle and working environment between the front drive, the rear drive and the four-wheel drive. The front-wheel drive is mainly responsible for front-wheel drive, the rear-wheel drive is mainly responsible for rear-wheel drive, and the four-wheel drive needs to consider the driving needs of both front and rear wheels. It is very important to choose the half axle suitable for your own vehicle type to ensure the normal operation and safety of the vehicle transmission system.
