Are the Rear Axle and Transfer Case Parallel?
1 Answers
Rear axle and transfer case are not parallel. Reasons why rear axle and transfer case are not parallel: The transfer case and engine must be at the same height because if they are too low, it may cause grounding, hence they are positioned higher. The rear axle, being connected to the suspension and wheels, needs to absorb shocks on bumpy roads, so it is positioned lower. Introduction to the principle of transfer case: The transfer case is a device that distributes the engine's power to the front and rear axles. From this perspective, the transfer case is essentially a component in four-wheel-drive vehicles. With the development of four-wheel-drive technology, the transfer case has continuously evolved, forming various styles to match different four-wheel-drive vehicles with varying demands. The basic principles and functions also differ accordingly. Introduction to the principle of rear axle: The rear axle refers to the rear drive shaft component of the vehicle's power transmission. It consists of two half-axles, enabling differential movement. At the same time, it is also a device used to support the wheels and connect the rear wheels. In front-wheel-drive vehicles, the rear axle is merely a trailing axle, serving only a load-bearing function. If the front axle is not the drive axle, then the rear axle becomes the drive axle, in which case, in addition to bearing the load, it also serves driving, deceleration, and differential functions. For four-wheel-drive vehicles, a transfer case is usually installed in front of the rear axle. Rear axles are divided into solid axles and semi-axles. Solid axles are paired with non-independent suspensions, such as leaf spring suspensions, while semi-axles are paired with independent suspensions, such as MacPherson suspensions.
