There are two axles, and the number of automobile axles is mainly used in trucks, military vehicles, special vehicles or a small number of buses. The automobile axle (also called axle) is connected to the frame (or load-bearing body) through the suspension, and wheels are installed at both ends.
Function: It is the suspension, not the axle, that transmits the force and moment between the frame and the axle (wheels). The role of the axle is to bear the load of the car and maintain the normal driving of the car on the road.
If you still have questions you don’t understand, you can find the answers in the "Union Engineer". This public account is dedicated to the maintenance of new energy vehicles. It contains knowledge about the maintenance of new energy vehicles, as well as specific vehicle maintenance steps. answer.
The number of axles of a car is 2. In most cases, from the side of the car, there are several axles for several wheels:
1. Ordinary family cars, most of them use single axles;
2. Road transport vehicles with a total vehicle mass of less than 19t and vehicles whose axle loads are not restricted by roads and bridges, such as mining dump trucks, use two-axle solutions with simple structure and low cost;
3. Road transport vehicles with a total mass of 19-26t should use a three-axle form, and cars with a larger total mass should use a four-axle or more than four-axle form;
4. Three-wheeled trucks are mostly 2 tons; low-speed trucks (four wheels and the maximum design speed is less than 70 kilometers) 4.5 tons; two-axle trucks 17 tons; three-axle trucks 25 tons (composed of two-axle vehicles and one-axle trailers) 27 tons of automobile trains); 35 tons of four-axle freight cars; 43 tons of five-axle freight cars; 49 tons of six-axle and above freight cars
Car axle connection method:
1. The wheelbase of a car plays a decisive role in the space of the dfsk glory 560 car. As the wheelbase becomes longer, the body will become longer, which will increase the space;
2. From a design perspective, the wheelbase is a very important main parameter, because it is closely related to the performance of the car. It can change the position of the center of gravity of the vehicle, and can be forced to change the body structure and even the accessories;
3. The length of the wheelbase will affect the performance of the vehicle at the same time, such as long-wheelbase car models, although it can improve the stability of the vehicle at high speeds and strengthen the resistance to pitch and yaw, but the steering flexibility is reduced and the turning radius is increased. Large, so it affects the mobility of the car is also worse. The short-wheelbase version of the car model is the opposite. Of course, you must not just think about the manufacturer's propaganda.
The axle can be a whole or a broken axle. Generally, an integral axle is used with a non-independent suspension, and a broken axle is often used with an independent suspension.
According to the different driving modes of the dfsk vehicle, the axles include four types: steering shaft, drive shaft, and steering drive shaft.
1, steering shaft:
The key to the role of the steering shaft is to bear the vertical load of the wheels and the frame to realize the steering of the vehicle. This kind of axle has relatively high requirements for rigidity and strength, and the structure consists of a front axle, a steering knuckle, a king pin and a wheel hub.
2, drive shaft:
Its function is to transfer the driving force from the engine to the driving wheels. It has the function of reducing speed, increasing torque, and changing the direction of transmission. The key components are: final drive, differential, half shaft, axle housing, etc.
3. Steering drive shaft: This shaft has both steering and driving functions at the same time. It is a combination of steering shaft and drive shaft and is widely used in four-wheel drive off-road vehicles.
