Introduction to candle suspension

The structural feature of the candle suspension is that the wheels move up and down along the axis of the kingpin rigidly fixed to the frame. The advantage of the candle suspension is that when the suspension is deformed, the positioning angle of the kingpin will not change, only the wheelbase and wheelbase will change slightly, so it is particularly beneficial to the steering stability and driving stability of the car. But the candle suspension has a big disadvantage: the lateral force when the car is running will be borne by the kingpin sleeved on the kingpin sleeve, resulting in increased frictional resistance between the sleeve and the kingpin, and more serious wear. Candle suspension is not used much now.
