What are the types of driving systems?
2 Answers
The types of driving systems are: 1. Wheeled; 2. Half-track; 3. Full-track; 4. Wheel-track hybrid. The working principle of the driving system is: fuel burns in the engine cylinder, causing the gas inside the cylinder to expand rapidly, pushing the piston to move and generating power. The power is output from the engine, transmitted through the clutch, gearbox, drive shaft, main transmission, differential, half-shaft, and driving wheels to propel the vehicle. The functions of the driving system are: 1. To receive the torque transmitted from the transmission system and generate the traction force of the road on the vehicle through the adhesion between the driving wheels and the road surface; 2. To transmit and bear the reaction forces and moments from the road surface acting on the wheels in various directions; 3. To support the total mass of the vehicle; 4. To cushion impacts, ensure smooth driving, and reduce vibrations.
In my years of car repair, I've seen various types of suspension systems. Independent suspension is the most common, such as MacPherson struts which are widely used in sedans due to their simple structure, low cost, and easy maintenance, though they have slightly more body roll during cornering. Double wishbone suspension is often found in sports cars, providing more stable handling and being suitable for aggressive driving. Non-independent suspensions like torsion beams are economical and used in most budget cars, being structurally robust but affecting comfort. Multi-link suspension is commonly used in mid-to-high-end cars, offering flexible tuning and high comfort. Air suspension is now popular in luxury cars, allowing for height adjustment and stiffness tuning to improve adaptability. Different systems affect how the car feels to drive; for example, non-independent suspensions feel bumpier on rough roads, while independent ones offer smoother cornering. The choice depends on usage: independent suspensions are comfortable for city commuting, while non-independent ones are durable for off-roading. Suspension design affects tire wear and ride experience, and modifications should match vehicle weight and road conditions to prevent damage to other components.
