The main components of semi-trailer hydrodynamic synchronous steering system include hydraulic pump, oil pipe, pressure fluid control valve, V-shaped transmission belt, oil storage tank and so on. This power assisted way is to convert part of the engine power output into hydraulic pump pressure to apply auxiliary force to the steering system, so as to turn the tires.low boy trailer factory-Hyzer

Low boy trailer's mechanical hydraulic power

Mechanical hydraulic power assist is the most common way of power assistance. It was invented in 1902 by an Englishman called Frederick W. Lanchester. However, the earliest commercial application was delayed to half a century later. In 1951, Chrysler applied the mature hydraulic steering power assist system to the imperial vehicle series. Due to the mature and reliable technology and low cost, it can be widely popularized.

The mechanical hydraulic power system mainly consists of hydraulic pump, oil pipe, pressure fluid control valve, V-shaped transmission belt, oil storage tank and so on. This power assistance is to convert part of the engine power output into hydraulic pump pressure to apply auxiliary force to the steering system in order to turn the tires.

Because the mechanical hydraulic power needs to consume a lot of engine power, people have improved a lot on the basis of mechanical hydraulic power, and developed a new electronic hydraulic power steering system that can save more energy than before. With this system, the steering oil pump is no longer directly driven by the engine but by the motor. What’s more, an electronic control system is also added so that the steering auxiliary force is not only related to the steering angle, but also related to the vehicle speed.

In addition, the hydraulic reaction device and liquid flow distribution valve are added to the mechanical structure. And the new electronic control system includes vehicle speed sensor, solenoid valve, steering ECU, etc.
