How to Conduct Annual Inspection on Full-Time Four-Wheel Drive Without Causing Damage?
1 Answers
Full-time four-wheel drive vehicles have a central differential with gears connecting the front and rear axles. When tested on a roller reaction force detection platform, a rotational speed difference will form between the front and rear axles during braking. The torque will be transferred to the central differential. If it is a multi-plate clutch-type central differential, excessive heat will be generated while the vehicle is not in motion, potentially causing the differential to burn out. For gear-type central differentials, such as Torsen differentials, this may lead to damage to the worm gear and worm wheel.
