Around 1975, almost all new cars in the US market were equipped with power steering systems, and in the European and Japanese markets, this technology gradually became a mainstream configuration. It can be said that the late 1970s was an important milestone in the popularization of power steering systems.

A power steering pump is a device specifically used to provide hydraulic power to a vehicle's power steering system. Its main function is to convert the engine's mechanical energy into hydraulic energy, and through the flow and pressure of hydraulic oil, the auxiliary steering system reduces the force required by the driver to turn the steering wheel.

In the hydraulic power steering system, the hydraulic assist provided by the hydraulic pump shares the force exerted by the driver, so that the rack and pinion are more evenly stressed during steering and reduce the rate of wear. Likewise, the electric motor assist in the electric power steering system plays a similar role.

The following are some common names for hydraulic steering gears: 1. Power Steering System 2. Assisted Steering 3. Hydraulic Power Steering System 4. Rack and Pinion Steering 5. Hydraulic Assist System

The main reasons for Mercedes-Benz power steering system failure: 1. Aging or damage to hydraulic system components 2. Insufficient or contaminated hydraulic oil 3. Electrical failure in the electric steering system 4. Wear of belts or pulleys 5. Mechanical problems in the steering system 6. Inadequate maintenance or improper use

From Toyota and Ford to BMW and Mercedes-Benz, these brands still choose hydraulic steering systems on some models because of their excellent reliability, excellent driving feedback and low manufacturing and maintenance costs.

The driver needs to exert more force when steering, which is especially dangerous for inexperienced drivers. In an emergency, the lack of steering power may cause the vehicle to fail to avoid obstacles in time or make correct steering operations, causing accidents.

Open the owner's manual and find the vehicle specifications or technical parameters section. Generally, the type of power steering system will be listed here. If the manual specifically mentions "hydraulic power steering system" or "electronic power steering system", then you can determine the vehicle's equipment.

Cadillac first introduced power steering in its production cars in 1952. At that time, power steering technology had been relatively mature, especially after Chrysler launched the first mass-produced car equipped with a hydraulic power steering system in 1951

Hydraulic power steering systems require oil because hydraulic oil is the primary medium of energy transfer. In this system, the pressure generated by the hydraulic pump needs to be transmitted through hydraulic oil.
