Can the steering hydraulic pump drive the hydraulic capstan at the same time?
Tolerable。Working principle of automobile hydraulic direction:The hydraulic power steering system is divided into traditional hydraulic power steering system HPS and electric control hydraulic power steering system EHPS according to control mode.The conventional hydraulic power steering system can be divided into two types: constant flow type and normal pressure type. Atmospheric pressure means that the whole hydraulic system is always kept high while the car is moving, no matter whether the steering wheel is turned or not. Constant flow refers to the car in motion, do not rotate the steering wheel, flow control valve in the middle position, the oil path to keep constant.
Because the power steering in a car is becoming more and more popular, the performance requirement is no longer simply in order to reduce operating intensity, but the requirement of ensuring steering portability while ensuring stability at high speed in low-speed u-turn. In order to achieve these requirements, only through speed sensing type power steering can be resolved. Speed sensing power steering is a power steering device that automatically adjusts the steering force as the speed changes. Speed sensing power steering plays an important role in improving vehicle handling stability and safety.At present, most of them are speed sensing type power steering, which has two basic forms:Hydraulic power steering system with electronic controlThe;Electric power steering system with electronic control.
HPS is usually composed of hydraulic pump, tubing, pressure flow control valve, V drive belt, oil storage tank and other components. No matter whether the car turns or not, the system is always in a working state with higher energy consumption. The common disadvantage of this kind of power steering is that the structure is complex, the power consumption is large, the discharge is easy to be generated, the steering force is not easy to control effectively, the power assisted system is easy to damage, and it is difficult to install and maintain. With the continuous extension of the highway and the car speed continues to improve, traditional hydraulic power steering exposed a fatal shortcoming, i.e. to ensure the steering light in the parking or low-speed U-turn, so when the car will be traveling at high speed when the feeling of "floating" feeling; and to ensure that the car at high speed when driving manipulation with moderate sense, it will feel when the steering is too heavy to stop or slow turn, you can't do both, which is decided by the structure of the traditional hydraulic power steering by the.
