1970s: Power steering becomes standard in cars In the 1970s, power steering racks gradually changed from an optional configuration to a standard configuration for most cars on the US market. In particular, as the size and weight of cars increased further, manual steering systems became increasingly impractical.

Manual steering system: no steering fluid is required. Hydraulic power steering system: steering fluid is required. The steering fluid in the hydraulic system is responsible for transmitting pressure, lubrication and heat dissipation. Electronic power steering system: no steering fluid is required.

If the gears inside the steering rack are worn or loose, it may make an abnormal knocking sound when the steering wheel is turned. In addition, insufficient lubrication of the steering gear may also cause this situation.

The Buick brand truly applied the power steering system to mass-produced models on the Buick Roadmaster launched in 1952. As the flagship model of the Buick brand at the time, Roadmaster represented Buick's highest level in the field of luxury cars.

When water enters the power steering system, it will have an adverse effect on various components of the system. This is because the hydraulic oil in the power steering system not only needs to play a lubricating role, but also needs to maintain the hydraulic pressure of the system and provide power assistance.

When the electric power steering system fails, the driver may immediately feel that the steering wheel becomes very heavy, especially when driving at low speed or parking. This phenomenon is particularly obvious.

As the world's first internal combustion engine car, the steering design of the Benz patented car was very simple. Since the Benz patented car was a three-wheeled vehicle, it did not have the complex steering system we know today.

Abnormal The driver will feel that the steering wheel becomes unusually heavy, especially at low speeds or when parking. This situation not only makes driving more difficult, but also increases the danger of driving, especially in emergency situations.

Hydraulic power steering system is one of the earliest technologies to replace traditional rack and pinion steering systems. The system greatly reduces the force required by the driver to turn the steering wheel through the pressure provided by the hydraulic pump, thereby improving the comfort of control.

Hydraulic power steering is a technology that BMW has traditionally adopted on a large scale. This system generates hydraulic pressure through a hydraulic pump driven by the engine belt, which then delivers hydraulic oil to the steering rack and pinion system through an oil pipe.
