High quality Steering booster pump WG9725471216
Working principle of gear pump: | Two gears of the same size mesh and rotate each other in a tight fit housing, the interior of the housing is similar to the "8" shape, the two gears are installed inside, the outer diameter and sides of the gears are closely matched with the housing. The material from the extruder enters the middle of the two gears at the suction inlet and fills this space, moving along the housing with the rotation of the teeth, and finally discharging when the two teeth mesh |
Steering power is to assist the driver to adjust the direction of the car, for the driver to reduce the strength of the steering wheel, of course, the power steering in the safety of the car, the economy also has a certain role.
As far as the power steering system configured on the current car and the information I can see, it can be roughly divided into three categories:
First, mechanical hydraulic power steering system;
Second, electronic hydraulic power steering system;
Third, electric power steering system.
Mechanical hydraulic power steering system
The mechanical hydraulic power steering system is generally composed of hydraulic pump, oil pipe, pressure flow control valve body, V-type transmission belt, oil storage tank and other components.
This system works regardless of whether the car is steering or not, and when the steering speed is low, the hydraulic pump needs to output more power to obtain a larger help. Therefore, to a certain extent, resources are wasted. It can be recalled that driving such a car, especially when turning at low speed, I feel that the direction is relatively heavy, and the engine is relatively laborious. And because the pressure of the hydraulic pump is very large, it is also easier to damage the power system.
In addition, the mechanical hydraulic power steering system is composed of hydraulic pumps and pipelines and cylinders, in order to maintain pressure, regardless of whether the steering power is needed, the system always needs to be in a working state, which is a reason for the consumption of resources.
General economic cars use mechanical hydraulic power systems more.
Electronic hydraulic power steering system
Main components: oil storage tank, power steering control unit, electric pump, steering machine, power steering sensor, etc., of which power steering control unit and electric pump are an integral structure.
Working principle: The electronic hydraulic steering power system overcomes the shortcomings of the traditional hydraulic steering power system. The hydraulic pump used by it is no longer driven directly by the engine belt, but by an electric pump, and all of its working states are calculated by the electronic control unit according to the speed of the vehicle, steering Angle and other signals. Simply put, at low speed, the electronic control unit drives the electronic hydraulic pump to output high power at high speed, so that the driver can save effort in the direction; When the car is driving at high speed, the hydraulic control unit drives the electronic hydraulic pump to operate at a lower speed, which does not affect the need for high-speed steering while saving part of the engine power.
Electric Power Steering (EPS)
The full English name is Electronic Power Steering, or EPS, which uses the power generated by the electric motor to assist the driver in power steering. The composition of EPS, although different car structural components are not the same, but generally the same. It is generally composed of torque (steering) sensors, electronic control units, electric motors, retarders, mechanical steering devices, and animal battery power supplies.
Main working principle: When the car is turning, the torque (steering) sensor will "feel" the torque of the steering disk and the direction of the intended rotation, these signals will be sent to the electronic control unit through the data bus, the electronic control unit will issue action instructions to the motor controller according to the transmission torque, the direction of the intended rotation and other data signals, so that the motor will output the corresponding size of the rotation torque according to the specific needs. This creates power steering. If it does not turn, the system does not work and is in standby(sleep) state waiting for the call. Due to the working characteristics of electric power steering, you will feel that driving such a car has a better sense of direction and is more stable at high speed, as the saying goes, the direction is not floating. And because it does not work when it is not turned, it also saves energy to some extent. Generally, high-end cars use such power steering systems more.
