Abstract

The invention relates to a vane pump, comprising a pump element arranged in a housing (2) made of light metal, wherein the pump element comprises a shaft (1), a rotor, vanes, a cam ring and at least one face plate. The shaft is guided in the housing by a ball bearing. The axial backlash of the ball bearing is compensated for by a plastic ring (5).

Description

Vane pump
The present invention relates to a kind of vane pump that is used for the hydraulic servo steering device, its structural principle is based on a pump element that mainly is arranged in the light metal housing.This pump element mainly comprises axle, rotor, blade, curve ring and end plate.According to structural series, also can use second end plate control panel in other words here.Axial end is a lid of being made by light metal equally.Axle seamlessly is connected through the ball bearing device guiding and with position rotor on it in housing.In the groove that radially is provided with of rotor, realize the installation of blade.The curve ring that rotationally fixedly is installed in housing or the lid surrounds rotor with the end plate/control panel or the lid of side.Between the slotted eye of the cylindrical circumference face of rotor and curve ring, form two sickle-shaped pump chambers.Its volume is obtained by the reaping hook section of maximum possible between two blades and the width of rotor or blade.
The oil that in sickle-shaped pressure chamber, produces stream is directed into the relative axle valve location, that be used for restriction pressure and volume flowrate on vertical or horizontal according to structural type, is restricted to regulated value and is continued to guide to the hydraulic servo steering device through a continuous flexible pipe.
Existing technology
As previously mentioned, the axle in the housing is guided by ball bearing device.For the position that keeps fixing, in assembly process, the outer ring of bearing is crossed in the shell rim bending.The operating temperature of this pump in vehicle approximately is 80 ℃.Under this temperature, produced bigger radial and axial gap owing to the housing thermal expansion coefficient different with bearing material.Need select special EC bearing (temperature compensation bearing) as ball bearing in order to compensate radial clearance.The EC bearing externally has two radial ring of being processed by PA11.
It is very expensive using this bearing.In addition, assembling also is difficult, and this bearing can not compensating axial clearance.
On some vehicles, the vibration of motor can produce violent vertical acceleration.At this moment will there be masterpiece to be used on the member of pump until 60g.Owing to the axial clearance on the bearing and violent vibration produce impulsive force, it possibly cause damage to pump.This power can hit bearing to making greatly from pump, this means that pump is malfunctioning fully.
Summary of the invention
Therefore task of the present invention is, avoids pump because that bearing causes is malfunctioning, and reduces the cost of bearing device.
This task is resolved through the characteristic of claim 1.Ball bearing through using standard can reduce cost.In addition, this bearing is axially passing through the plastic hoop pretension.The gap that produces owing to temperature variation axially is being compensated through this plastic hoop.Therefore guarantee the axial fixed installation of bearing.Axial clearance especially under higher temperature owing to the different expansibility of material produces.And thereby the aluminium material of opposite housing at low temperatures shrinks generation stress.This also can be through the plastic hoop compensation.
When selecting material, confirmed that plastics are best choice for the nose balance ring.For example the cup spring of metallic material is inappropriate on the contrary, because it can produce abrasion on housing.
Embodiment
Next will be through the concise and to the point elaboration of accompanying drawing vane pump of the present invention.
Accompanying drawing is following:
Fig. 1 according to existing technology the axle bearing device,
Fig. 2 according to according to the invention scheme the axle bearing device.
Fig. 1 has showed the details according to the bearing device of the axle (1) of the vane pump of existing technology.Expensive EC bearing (3) is set in the housing (2) of pump.This EC bearing externally has two radial ring that are used to compensate radial clearance.
Fig. 2 has showed according to the details of bearing device according to the axle (1) of the vane pump of invention scheme.The ball bearing (4) that in the housing (2) of pump, sets up standard, it is axially passing through plastic hoop (5) pretension.Plastic hoop (5) be arranged in the axial direction ball bearing on a side of pump rotor.
