Electric vehicle bearings are one of the important components of electric vehicles, which play a role in supporting and reducing friction.
It is widely used in the motor and wheels of electric vehicles.
1. The role of the bearing A bearing is a mechanical element that can transmit force and torque between two moving parts.
In the electric vehicle, the bearing has the following functions:-supporting function: the bearing can support the motor rotor and the wheel shaft to ensure the normal operation of the electric vehicle.
-Reduce friction: The rolling elements (such as balls, cylinders, etc.) inside the bearing can reduce the contact area between components, thereby reducing friction and energy loss, and improving the efficiency of electric vehicles.
-Guiding function: The bearing can maintain the relative position of the motor rotor and the wheel shaft to ensure that they move on the correct track.
-Bearing load: The bearing can withstand various loads generated during the operation of the electric vehicle, such as radial load and axial load, to ensure the stability and safety of the electric vehicle.
2. Types of bearings The bearings commonly used in electric vehicles include ball bearings, roller bearings and sliding bearings.
They each have different structures and characteristics:-Ball bearings: Ball bearings are the most common type of bearings, with a simple structure and good load-bearing capacity.
Ball bearings are suitable for applications under general loads and speeds in electric vehicles.
The gearbox is a mechanical device used to change the torque and speed of the engine to adapt to different road conditions and workloads. It is usually composed of gears, gears, clutches, etc. in the transmission system. It is widely used in automobile, engineering machinery, ship, aircraft and other fields.

Related Functions and Applications of Automobile Front and Rear Axles
The axle (also called the axle) is connected to the frame (or load-bearing body) through the suspension, and wheels are installed at both ends. The vertical load on the frame is transmitted to the wheels through the axle; the rolling resistance, driving force
