The car chassis consists of four parts: the transmission system, the running system, the braking system, and the steering system. Here are the detailed introductions: 1. Transmission System: The transmission system is generally composed of the clutch, gearbox, universal transmission device, main reducer, differential, and half-shaft. The power generated by the car engine is transmitted to the driving wheels through the transmission system. 2. Running System: The running system consists of the car's frame, axle, wheels, and suspension. The function of the running system is to support the various parts and assemblies of the car, transmit and withstand various loads above and below the car to ensure the normal driving of the car. 3. Steering System: The specialized mechanism used to change or restore the driving direction of a car is called the car steering system. According to the different sources of steering power, the steering system can be divided into mechanical steering systems and power steering systems. The function of the steering system is to ensure that the car can travel in the direction selected by the driver. 4. Braking System: The function of the braking system is to decelerate the car, stop it, and ensure reliable parking. The car braking system generally includes two sets of independent braking systems: the service braking system and the parking braking system. Each braking system includes the brake and the brake transmission mechanism.

What to Do When the Car Touchscreen Malfunctions?

Locate the reset (restore factory settings) button on the device, which is a small built-in button that can be found on the back or side of the device. After rebooting, check if the screen responds. If it does, quickly proceed to calibrate the screen in the settings. If the screen still doesn't respond after rebooting, and if the battery is removable, charge the battery separately, making sure to use a dock charger. If the battery is non-removable, use a wired charger and ensure the charging time is sufficiently long. If none of the above methods work, then repair is the only option.

Will points be deducted for parking the car in the opposite direction?

Parking the car in the opposite direction will result in a fine, as it constitutes reverse parking. When temporarily parking a motor vehicle on the road, the following regulations must be observed: roadside parking should be close to the right side of the road—motor vehicle drivers must not leave the vehicle and should depart immediately after loading or unloading passengers or goods. The distance from the road edge should not exceed 0.5 meters—the right side of the vehicle body should be no more than 0.5 meters from the road edge. No reverse driving is allowed—according to the regulations for parking direction, motor vehicles must not reverse when temporarily parking on the roadside. Even reversing to park or waiting for a parking space is considered illegal parking.
