1 Answers
"Axle", which is the bearing connecting two wheels, is also called "wheel axle". Each pair (left and right) of tires is connected by an "axle", and the so-called number of axles refers to the number of wheel axles. Below is a related introduction to axles: Introduction to Car Axles: Axles are mainly used in cargo trucks, military vehicles, special vehicles, or large buses. The axle is connected to the frame (or load-bearing body) through the suspension, with wheels installed at both ends. According to the number of axles, they can be divided into: single axle, double axle, front four rear four, front four rear eight. More axles include semi-trailers, two-axle trailers with three axles, and three-axle trailers with three axles. Ordinary family cars generally use a single axle. Highway transport vehicles with a total mass of less than 19t and vehicles whose axle load is not restricted by roads or bridges, such as mining dump trucks, use a simple and low-cost two-axle solution. Highway transport vehicles with a total mass of 19-26t adopt a three-axle form. Function of Axles: The function of the axle is to bear the load of the car and maintain the normal driving of the car on the road.
