What's wrong with using an electric heavy steering wheel in cold weather?

The steering wheel is getting heavier and heavier, mainly due to the following reasons:

1, insufficient pressurized liquid/oil.

Power steering oil is a kind of medium oil used in automobile power pump, which plays the role of transmitting steering force and buffering. Power steering oil needs to be changed regularly, and check for oil leakage. When the power steering oil is insufficient, the direction will be very heavy.

The tire pressure is too low.

Too low tire pressure will increase the contact area between the tire and the road surface, increase the friction, and increase the steering difficulty, resulting in a heavy steering wheel, which is not conducive to driving safety.

3. Toes

Toe will also affect the steering of the car. The meaning of toe-in is quite complicated. Simply put, it is to make the steering wheel automatically return to the correct position to ensure that the car can travel in a stable straight line. So when there is a problem in this area, it will also cause the direction to sink.

The steering gear and booster pump are out of order.

There are also steering gears and booster pumps that affect the steering of cars. When these two important components fail, it will lead to steering difficulties. Whether it is universal joint, chassis suspension balance bar, plane bearing and other issues can not be ignored.

5, bearing with too tight.

The close fit between the rolling bearing and the sliding bearing connected to each steering system will lead to poor lubrication and seizure of the bearing.

In addition, there are two specific manifestations of directional weight, one is that one direction is heavy and the other is that both sides are heavy. Neither situation should be underestimated. It is necessary to specifically check the causes of mechanical parts and power-assisted systems, or to rule out whether there is oil leakage, air intake and other seal damage. And we must pay attention to the warning information sent by the car, find and solve the problem as soon as possible, and avoid accidents.
