At present, the technology of automobile steering systems is gradually developing into three trends

 

Pure hydraulic power steering system HPS: Currently widely used in hydraulic steering systems, the engine drives the steering pump. Since it consumes the power of the engine all the time, it has no benefit to the reliability and energy saving of the oil pump itself, and is mainly used in heavy truck models;

 

A pure electric steering system EPS consists of "torque sensor + ECU + servo motor + mechanical steering gear." This technology will be fully applied to passenger cars, replacing the existing hydraulic steering, reducing engine fuel consumption, and contributing to energy savings and environmental protection.

 

Electric hydraulic steering system EHPS: The steering pump driven by the engine is changed to the steering pump driven by the servo motor. This technology has been fully applied to pure electric and hybrid buses.

 

 

 

 

Product Features

The steering pump is driven by a fully enclosed, high-efficiency permanent magnet synchronous motor, which improves the sealing and reliability;
The power transmission is carried out by a stable, impact-proof flexible coupling, which greatly improves the service life;
The overall protection level reaches IP67, and the double insulation design is adopted to ensure that there is no electrical conduction between the motor and the oil pump;
The motor housing and the steering pump housing are all made of aluminum alloy, which has excellent performance such as low noise, light weight, and fast heat dissipation

 

 

 

 

 

 

Application

 

The EHPS system is used in the following scenarios

 

Electric buses and heavy vehicles:

 

Electric buses and heavy electric vehicles require higher power support due to their large body and heavy weight. The EHPS system can provide sufficient hydraulic power to ensure that the driver can easily control the direction.

 

The use of the EHPS system can avoid the belt drive problem of the traditional hydraulic power system and improve energy efficiency and steering accuracy.
