How many belts are there in a car and what are they called?
2 Answers
There are usually three belts in a car, as follows: 1. Timing belt: The timing belt plays a connecting role, linking the timing wheel on the upper part of the engine cylinder head and the timing wheel on the crankshaft. The timing wheel is connected to the camshaft, which has cams. The contact point of the cam is the small rocker arm, and the rocker arm generates pressure through the power transmitted by the timing belt, serving to lift. 2. Fan belt: A belt driven by the crankshaft. Its main purpose is to drive the engine fan and water pump. 3. Alternator belt: The belt on the alternator is driven by the engine through a pulley. Some are driven by a single belt, while others have a dedicated alternator belt.
Ah, talking about car belts, as someone who's been driving for over 20 years, I've got plenty of insights. Typically, there are three to five belts in a car: the timing belt—it controls the engine's intake and exhaust valves, ensuring smooth operation; the alternator belt—responsible for driving the alternator to charge the battery; the air conditioning compressor belt—activates the compressor when using AC in summer; and the power steering belt—makes steering effortless. Some older cars also have a water pump belt to drive the cooling system. Regularly checking these belts prevents aging and snapping, which could otherwise lead to a troublesome breakdown. In my younger days, I experienced a timing belt snap, causing severe engine damage and a costly repair of several thousand dollars. Since then, I’ve made it a rule to replace it every 80,000 kilometers. Proper maintenance keeps the car reliable and worry-free. I recommend listening for unusual engine noises—a high-pitched squeal is often a warning sign of loose belts.
