Can an Inter-Axle Differential Lock Turn?
2 Answers
An inter-axle differential lock can turn. Depending on the locking method, differential locks can be categorized into: 1. Forced Locking Type: This type of differential lock is set on a common symmetrical bevel gear differential. It has a simple structure, is easy to manufacture, and has a high torque distribution ratio. 2. High-Friction Self-Locking Type: This includes structures like friction plate type and slider cam type. The friction plate type locks the differential through the frictional torque generated when the friction plates slide relative to each other. 3. Jaw Type: The jaw type is commonly used in medium and heavy-duty trucks. 4. Torsen Type: The Torsen differential is a new type of inter-axle differential. It has a wide and adjustable torque transmission range, making it widely used in the central differential of all-wheel-drive cars and the inter-wheel differential of rear-drive axles. 5. Viscous Coupling Type: Some four-wheel-drive cars use a viscous coupling as a differential. Silicone oil has a high thermal expansion coefficient. When the speed difference between the two axles is too large, the temperature of the silicone oil rises sharply, and its volume expands continuously. The silicone oil pushes the friction blades to tightly combine, directly connecting the drive shafts at both ends of the viscous coupler as one, i.e., the viscous coupler locks.
As an off-road driving enthusiast, I'd like to share some insights about using differential locks in corners. Differential locks are designed to lock the axle and synchronize wheel rotation for improved straight-line traction, such as when getting unstuck from mud or sand. However, they shouldn't be used when turning. Corners require the inner wheels to rotate slower and outer wheels faster to follow the turning trajectory. With the differential locked, all wheels are forced to rotate at the same speed, causing tires to drag and screech across the surface. At best, this leads to severe tire wear; at worst, it can damage the differential or even suspension components. I once forgot to unlock before a mountain curve and nearly lost control in a skid. The aftermath required new tires and expensive differential repairs. Remember: only engage locks for straight-line obstacles, always manually unlock before corners. Safety first - don't cut corners with improper operation. After off-roading, regularly inspect tires and check for aging differential lock mechanisms.
