Where are the rear axle and transfer case located in a car?
1 Answers
The rear axle, also known as the drive axle or live axle, is used to support the vehicle frame; the transfer case is mostly located in front of the rear driveshaft and behind the transmission. Rear Axle: It refers to the rear drive shaft component of the vehicle's power transmission system. It consists of two half-axles that allow for differential movement. Additionally, it serves as the device that supports the wheels and connects the rear wheels. In front-wheel-drive vehicles, the rear axle is merely a trailing axle, functioning only as a load-bearing component. Transfer Case: The transfer case is mostly located in front of the rear driveshaft and behind the transmission. Some four-wheel-drive vehicles are equipped with a transfer case, which is a crucial component. The transfer case contains oil that needs to be replaced regularly. If not replaced for a long time, it can lead to gear wear inside the transfer case. Some vehicles feature highly complex four-wheel-drive systems, and these vehicles typically have a transfer case. Many rugged off-road vehicles use a part-time four-wheel-drive system, which allows mode switching. Such systems usually have three modes: high-range four-wheel drive, high-range two-wheel drive, and low-range four-wheel drive. When switched to low-range four-wheel drive, the wheel torque is amplified, enhancing the vehicle's off-road capability. High-range four-wheel drive and high-range two-wheel drive modes are suitable for normal paved roads. The transfer case is particularly vulnerable to damage in extreme driving conditions, so drivers should operate it carefully to prevent damage. Regular maintenance is essential during daily use. Some four-wheel-drive vehicles are also equipped with a transfer case. The primary function of the transfer case is to distribute power between the front and rear axles, while the power to the two wheels on the same axle is distributed by the differential. Some vehicles feature highly intelligent four-wheel-drive systems that improve cornering performance and handling.
