What does the two locks on the Haval Big Dog mean?
2 Answers
Haval Big Dog's two locks refer to the central differential lock + rear axle electronically controlled differential lock. The function of the two locks: In actual use, these two locks - the central differential lock + rear axle electronically controlled differential lock assist each other and complement each other. When dealing with complex road conditions, they simultaneously solve the problems of four-wheel speed synchronization and power wheel distribution, greatly improving the effective passability and safety when facing complex road conditions. The meaning of differential lock: A differential lock refers to when one drive wheel slips, locking the differential housing and the half-shaft into one unit, causing the differential to lose its differential function, allowing all torque to be transferred to the other drive wheel.
The two locks on the Haval Big Dog, in my opinion, refer to its differential lock system. Simply put, it makes all four wheels more powerful during off-roading. As a car enthusiast, I once drove a friend's Haval Big Dog for a mountain camping trip and used this feature. It includes front and rear axle locks. When you encounter slippery conditions like mud or snow, pressing a button locks the differential, evenly distributing power to all wheels, preventing the awkward situation where one wheel spins while another gets no power. This significantly improves the vehicle's off-road capability and safety, especially during outdoor adventures where getting stuck is a concern. I remember crossing a small river where other vehicles struggled, but the Big Dog handled it effortlessly while also reducing wear on the drivetrain. Maintenance is hassle-free—just occasional checks on the wiring. Overall, this design makes rugged SUVs more practical, perfect for those who love challenges.
