An automobile chassis consists of four major systems: the transmission system, the running gear system, the steering system, and the braking system. The function of the car chassis is to receive power from the engine, enable the vehicle to move, and ensure that the car can operate normally according to the driver's control. The roles of each component of the car chassis are as follows: 1. Transmission system. The function of the transmission system is to transmit the engine's power to the driving wheels. Different vehicles may have slight variations in the composition of their chassis. 2. Running gear system. The running gear system supports and installs various components and assemblies of the vehicle, transmitting and bearing various loads from both the vehicle body and the ground to ensure normal operation. It mainly consists of the frame (body), axles, suspension, and wheels. 3. Steering system. The steering system ensures that the car can move in the direction selected by the driver. It primarily includes the steering control mechanism, steering gear, and steering linkage. 4. Braking system. The braking system enables the car to decelerate, stop, and remain reliably parked. The automobile braking system generally includes two independent braking systems: the service brake system and the parking brake system. Each braking system consists of brakes and brake transmission mechanisms.

How Often Should Small Car Tires Be Replaced?

Small car tires should generally be replaced every 5 years or after 80,000 kilometers. Below are some relevant details about tire usage:1. The longer tires are used, the higher the risk of tread deformation and blowouts becomes.2. To extend the service life of tires, it is recommended to rotate the tire positions every 10,000 to 20,000 kilometers. The purpose of front-to-rear rotation is to ensure more even tire wear.3. Due to the thermal expansion and contraction of air, it is advisable to check and inflate tires during cold winter months. Below are the steps for replacing a tire:1. Retrieve the spare tire and jack. Place the jack under the vehicle frame near the tire to be replaced. Ensure the jack contacts the metal part of the frame.2. Raise the jack until it supports (but does not lift) the car.3. Remove the hubcap and loosen the nuts by turning them counterclockwise.4. Pump or turn the jack to lift the tire off the ground.5.

Can a Dash Cam Also Record Inside the Car?

In general, a dash cam can record the road conditions in front of the vehicle. Some dash cams come with dual lenses, enabling simultaneous front and rear recording. In addition to the front-facing camera, they include a rear camera to capture the situation behind the vehicle. A dash cam is an instrument that records images, sounds, and related information during vehicle operation: 1. It can also serve as a parking monitor. Once installed, the video footage should not be edited, as tampering may render it useless in the event of an accident. 2. Most dash cams do not have built-in memory and rely on memory cards or external digital hard drives for storage expansion. 3. To meet larger video storage needs, users must configure the memory capacity based on personal requirements. Generally, the larger the memory, the higher the price of the dash cam. The appropriate memory size depends on the recording resolution and storage requirements of the camera. High-definition dash cams offer 720p and 1080p resolutions. A 4GB card can record approximately one hour of 720p video, while 1080p video occupies nearly twice the space of 720p.
