Problems solved by technology

[0006] In the present invention, a resistance hole is provided in the oil inlet chamber, and the oil supply amount from the oil inlet chamber to the compression chamber is constant. By designing the size of the resistance hole, the oil supply amount can be controlled at the idle speed of the engine (such as 700 rpm), and the Satisfy the rated flow rate of the "pump", so that when the engine exceeds 700 rpm, the resistance hole can limit the oil supply from the oil inlet chamber to the compression chamber to prevent the pressure and temperature in the chamber from increasing, thereby solving the problem of chamber sweeping, Problems such as jamming, deformation and breakage of pressure regulating valve spring, oil leakage of oil seal, short service life, etc.

Abstract

A boosting pump for turning of automobile is composed of a pump body and its cover. The pump body consists of oil inlet and oil chamber. The cover comprises compressing chamber, cavity and oil outlet. The compressing chamber is driven by active axle with oil seal. It features that there is a resistance hole on the channel between oil chamber and compressing chamber. It can prevent too high temp. and pressure in cavity, avoiding many problems such as jamming, deformation of spring, oil leakage, etc.

Description

technical field [0001] The present invention relates to automobile components, in particular to steering pumps for automobiles. Background technique [0002] With the rapid development of the world's automobile industry, people have higher and higher requirements for the performance and driving suitability of automobiles. Therefore, in order to meet people's requirements for the reliability and portability of automobile steering systems, that is, the requirements for automobile steering sensitivity, People use hydraulic power steering system in automobile steering system. The hydraulic power steering system includes a power steering pump and a steering gear. It requires that the output flow of the power steering pump cannot be high pressure or lower than a constant value. If it can be maintained at the same time, and can meet the performance requirements of the steering gear at the bottom speed of the engine, the power steering pump can effec...
