What Systems Does the Chassis Consist Of?

The chassis is composed of four major systems: the transmission system, steering system, braking system, and running gear system. Below is an introduction to these four major systems of the automotive chassis: 1. Transmission System: The function of the transmission system is to transmit the engine's power to the driving wheels. Different vehicles have slightly different chassis compositions. For example, in trucks and some sedans, the chassis typically consists of a clutch, manual transmission, universal drive, and drive axle. However, more and more modern sedans use automatic transmissions, where the chassis includes an automatic transmission, universal drive, and drive axle, replacing the clutch and manual transmission. For off-road vehicles (including SUVs, or Sport Utility Vehicles), a transfer case is also included. 2. Running Gear System: The function of the running gear system is to support and install various components and assemblies of the vehicle, transmitting and bearing various loads from both inside and outside the vehicle to ensure normal operation. It mainly consists of the frame (or body), axles, suspension, and wheels. 3. Steering System: The function of the steering system is to ensure the vehicle can move in the direction selected by the driver. It primarily includes the steering control mechanism, steering gear, and steering linkage. Most modern vehicles are equipped with power steering systems. 4. Braking System: The function of the braking system is to decelerate, stop the vehicle, and ensure reliable parking. The automotive braking system generally includes two independent braking systems: the service brake system and the parking brake system. Each braking system includes brakes and brake transmission mechanisms. Modern vehicles' service brake systems are usually equipped with an Anti-lock Braking System (ABS).
When it comes to the car chassis, I think of it as a large frame supporting the entire vehicle, primarily composed of several key systems. From my experience in modifications, the powertrain system is the first core component, responsible for transmitting the engine's power to the wheels, including the transmission and driveshaft. The steering system is also crucial, controlling the direction when turning, with components like the steering wheel and gear mechanism. The braking system is indispensable, using brake discs and hydraulic components to stop the vehicle. The suspension system handles road bumps, utilizing shock absorbers and springs for cushioning. Lastly, the wheel system, including tires and rims, supports the car's movement. In daily driving, these systems are all essential. Any malfunction, such as a broken suspension causing excessive shaking on rough roads, can severely impact safety and comfort. During maintenance, I always check their connections for firmness, as regular upkeep can prevent major issues. After all, a healthy chassis ensures the vehicle's longevity.
From my daily driving perspective, the chassis serves as the foundation of a car, encompassing several major systems: First is the drivetrain, which handles power transmission, such as the components connecting the engine to the wheels. Next is the steering system, allowing me to precisely control direction and navigate turns smoothly. There's also the braking system, utilizing brake discs and pipelines to ensure safe stops. The suspension system absorbs road impacts, reducing ride discomfort. The wheel system, including tires, makes direct contact with the road. These systems work closely together – for instance, during rain or snow, a good chassis enhances traction and stability. I've noticed that chassis issues, like drivetrain malfunctions causing jerky movements, can directly affect driving efficiency. I recommend regular maintenance checks to prevent minor issues from escalating. Simple measures like tire pressure adjustments can also extend lifespan.
