Brief Description of the Principle
Its working principle is as follows: There are two towing seat supports on each side below the seat cover plate, which is made of pressed steel plate. These supports are connected to the seat cover plate by pins. The towing seat base can rotate back and forth relative to the seat cover plate around the pins. The bottom surface of the towing seat base is bolted to the trailer being towed. A locking mechanism consisting of horseshoes, wedges, hooks, adjusting discs, crossbars, tie rods, and springs is installed below the seat cover plate. The horseshoes are fixed to the seat cover plate, and the hooks, tie rods, and crossbars are connected by pins. The wedges are also connected by pins, and the tie rods are connected to the reinforcing ribs below the seat cover plate by springs. Its key feature is that the two rear ends of the saddle-shaped seat cover plate are large arcs, with a butterfly-shaped concave surface in the middle, dividing the entire plane into five similarly sized sections.
Control System
The Traction Control System (TCS), also known as ASR or TRC, ensures optimal traction for the vehicle under various driving conditions. The traction control system is controlled by a computer. This computer detects the speed of the four wheels and the steering wheel angle. When the car accelerates, if it detects a large difference in speed between the drive wheels and non-drive wheels, the computer immediately determines that the driving force is excessive and issues a command signal to reduce the engine's fuel supply, thereby reducing the driving force and decreasing the slip rate of the drive wheels. The computer uses a steering wheel angle sensor to understand the driver's steering intention and then uses left and right wheel speed sensors to detect the speed difference between the left and right wheels; this determines whether the degree of steering matches the driver's steering intention. If understeering (or oversteering) is detected, the computer immediately determines that the driving force of the drive wheels is excessive and issues a command to reduce the driving force to achieve the driver's steering intention.
The traction control system prevents the drive wheels from spinning freely on slippery surfaces such as snow, allowing the vehicle to start and accelerate smoothly. Especially on snowy or muddy roads, the traction control system ensures smooth acceleration performance and prevents the vehicle from lateral movement or fishtailing due to drive wheel slippage.
