Does the steering wheel need lubrication?

[DeMelanie]

Electronic power steering does not require lubrication. Non-electronic power steering can be lubricated, but it is not necessary because the bearings of the rotating mechanism are generally sealed. Additional information: Relevant knowledge about steering wheels is as follows: 1. Definition: A wheel-shaped device used to control the direction of cars, ships, aircraft, etc. It is connected to the steering shaft via splines and converts the force applied by the driver on the edge of the steering wheel into torque, which is then transmitted to the steering shaft. The steering wheel is the part of the car that the driver interacts with the longest, uses most frequently, and reflects the most concentrated user demands. 2. Design: The steering wheel is typically circular in shape, while high-end sports models may flatten the bottom arc. This design is now also applied to regular models. 3. Design features: Ergonomic considerations, such as convex pressing surfaces, mountain-like designs on the back of the grip, and appropriate hardness and roughness.
