What are the front wheels of a car
The front wheel hub is a metal part that is mounted on the axle of the front wheel of an automobile, usually called the hub or rim. It is a cylindrical structure of the tire inner profile supporting the tire, the center is mounted on the shaft, and mainly plays the role of supporting and fixing the tire .
The basic function of wheel hub
support and fixed tire : The wheel hub supports and fixes the tire through its design to ensure the stability and safety of the vehicle.
bearing, steering, driving and braking : the wheel hub not only carries the weight of the vehicle, but also participates in the steering, driving and braking process of the vehicle, which directly affects the handling stability and driving safety of the vehicle .
Type and material of wheel hub
by material : Common wheel hub materials include steel and alloys such as aluminum alloy. Aluminum alloy wheels are favored by high-end models because of their light weight, high strength and corrosion resistance, while steel wheels are suitable for ordinary models because of their price.
Classification by diameter and width : The diameter and width of the wheel hub will affect the choice of tires and the effect of use. Larger wheels allow wider tyres to be fitted, providing better grip and handling .
Wheel hub maintenance and maintenance
Avoid collision : Avoid collision between tire or wheel hub and hard objects to prevent wheel hub deformation.
Avoid high temperature and cold water cleaning : Avoid using cold water to clean the wheel hub at high temperature to prevent damage caused by thermal expansion and cold contraction.
regular cleaning : vehicles parked in humid environment for a long time should be cleaned regularly to prevent salt corrosion .
The main functions of the front wheels of automobiles include supporting the body, transmitting power, cushioning external impact, affecting handling and safety .
Firstly, the main function of the wheel hub is to support the body . It is the key component of body weight transfer to the road surface, bearing the lateral load, driving force and braking torque during turning .
The wheel hub supports the weight of the vehicle by installing the tire, ensuring that the vehicle can drive stably on the road .
Secondly, the wheel hub transmits power during the driving of the car. The power produced by the engine is transmitted to the wheels through the transmission system, which in turn drives the tires to rotate, thus making the vehicle go .
The design and size of the wheel hub also affects the contact area between the tire and the road surface, which in turn affects the handling performance .
In addition, wheel hub can buffer external impact , reduce body vibration, improve ride comfort .
When the vehicle is driving on the uneven road surface, the wheel hub can absorb part of the impact force, reduce the vibration transmitted to the body, so that the passengers in the car feel a more stable driving experience .
Finally, the design and size of the wheel also affect the braking performance and the choice of tires . Large-size wheels can be matched with a larger brake system and high-performance tires to improve the stability and handling of the vehicle, but when choosing large-size wheels, it is necessary to pay attention to the impact of weight and inertia on acceleration and braking performance .
