What does a compact chassis mean?
1 Answers
A compact chassis refers to a vehicle with soft suspension. The chassis serves to support and install the car engine and its various components and assemblies, forming the overall shape of the vehicle. It also receives the power from the engine to enable the car's movement and ensure normal driving. The chassis consists of four main parts: the transmission system, the running gear, the steering system, and the braking system. Below are detailed introductions: 1. Transmission System: The transmission system generally includes 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. The transmission system functions to reduce speed, change gears, reverse, interrupt power, provide inter-wheel differential, and inter-axle differential. Working in conjunction with the engine, it ensures the car's normal operation under various conditions, offering good performance and fuel efficiency. 2. Running Gear: The running gear consists of the car's frame, axles, wheels (note), and suspension. 3. Steering System: The specialized mechanism in a car used to change or restore its driving direction is called the steering system. Depending on the steering energy source, steering systems can be divided into two main categories: mechanical steering systems and power steering systems. 4. Braking System: A series of specialized devices in a car that apply a certain force (mainly from the road surface) to specific parts (mainly the wheels) to enforce a certain degree of braking are collectively called the braking system. Its functions include: forcing a moving car to decelerate or even stop as required by the driver; ensuring a parked car remains stable under various road conditions (including on slopes); and maintaining a stable speed for a car driving downhill.
