Abstract
The utility model discloses a power steering pump which comprises a pump body. A transmission component and a pump core component are arranged in the pump body, and a pressure cavity communicated with an oil channel is further formed inside the pump body. The power steering pump is characterized in that a mounting hole communicated with the pressure cavity is formed in one side of the pressure cavity, a pressure sensor is arranged in the mounting hole, the induction end of the pressure sensor faces the pressure cavity, and the other end of the pressure sensor is connected with a control center of an automotive engine. The power steering pump can adjust operating speed according to the hydraulic intensity of oil in a high-pressure cavity, and therefore the strength of output assisting power is adjusted to be kept moderate, and driving comfort and safety are guaranteed.
Description
Technical field
The utility model designs a kind of boosting pump for car steering.
Background technique
The effect of power assistance pump for steering is for automobile power-assisted steering system provides power source so that steering boost system provides power steering for automobile, and its working principle is by extracting fluid and changing high-voltage oil liquid into and provide hydraulic power for steering boost system.The operation power of power assistance pump for steering distributes from motor car engine, therefore when galloping, the running of power assistance pump for steering is just very fast, when automobile low speed driving, the running of power assistance pump for steering is just slower, but this can cause automobile when high speed steering because power-assisted excessive and unstable, low speed rotation to time because power-assisted is too small, resistance is too large.
Summary of the invention
For the deficiencies in the prior art, during problem to be solved in the utility model, provide a kind of power assistance pump for steering that can regulate according to internal oil pressure its running speed.
For this reason, the utility model is realized in the following way: a kind of power assistance pump for steering, comprise the pump housing, in the described pump housing, be provided with transmitting assemblies and pump core assembly, in the described pump housing, also have and the pressure chamber of fluid channel connection, it is characterized in that: described pressure chamber one side is provided with the mounting hole being communicated with pressure chamber, in described mounting hole, is provided with pressure transducer, the induction end of described pressure transducer is towards pressure chamber, and the other end is connected with the control centre of motor car engine.
Described pressure transducer is provided with annular groove, in described annular groove, is provided with rubber ring, and described rubber ring and pressure transducer are together placed in mounting hole and press closer on mounting hole inwall.
In the utility model, hyperbaric chamber is that pump body is for cushioning the cavity of high-voltage oil liquid, from the high-voltage oil liquid of pump housing output, all can flow through from hyperbaric chamber, therefore be located at the hydraulic pressure that pressure transducer in the mounting hole being communicated with hyperbaric chamber can detect current pump housing output fluid in real time, and notify control centre to reduce motor when hydraulic pressure is too high to distribute to the power of power assistance pump for steering, and strengthen, distribute to the power of power assistance pump for steering when hydraulic pressure is too low, with the outputting power of this real-time adjusting power assistance pump for steering, the output power-assisted of vehicles steering system makes it mate with the travelling speed of current automobile, travelling comfort and the Security of driving have been guaranteed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pressure transducer in the utility model.
Embodiment
Shown in accompanying drawing 1, this power assistance pump for steering, comprise the pump housing 3, in the described pump housing 3, be provided with transmitting assemblies and pump core assembly, described transmitting assemblies comprises transmission shaft 1 and belt pulley 2, described pump core assembly comprises stator 7, rotor 9 and blade 8, described transmission shaft 1 is connected with rotor 9, in the described pump housing 3, also there is the pressure chamber 4 with fluid channel connection, described pressure chamber 4 one sides are provided with the mounting hole 5 being communicated with pressure chamber, in described mounting hole 5, be provided with pressure transducer 6, the induction end of described pressure transducer 6 is towards pressure chamber 4, the other end is connected with the control centre of motor car engine, described pressure transducer 4 upper ejector pin parts and housing parts are all provided with annular groove 10, in described annular groove 10, be provided with rubber ring 11, described rubber ring 11 is together placed in mounting hole 5 and presses closer on mounting hole 5 inwalls with pressure transducer 6, rubber ring 11 makes pressure transducer 6 be placed in more securely in mounting hole 5 and can play very good seal action, prevent that fluid from spilling in hyperbaric chamber.During automobile running, motor by part power by belt pulley pass 2 pass power assistance pump for steering make its running, power assistance pump for steering from oil tank, extract in the running fluid and change into high-voltage oil liquid carry to steering boost system, for it, provide power.When the fluid channel flow of high-voltage oil liquid in the pump housing and hyperbaric chamber 4, pressure transducer 6 can detect the current hydraulic pressure of fluid in real time, and when hydraulic pressure is too high, notify power that control centre reduces to distribute to power assistance pump for steering to reduce to export power-assisted, when hydraulic pressure is too low, notify the power that power assistance pump for steering is distributed in control centre's increasing to export power-assisted to strengthen, make power steering maintain applicable size, thereby guaranteed travelling comfort and the Security of driving.
Claims (2)
