Abstract
Disclosed is a principal shaft transmission mechanism for a vane steering pump, pertaining to an oil transferring pump which is provided with a sealing device and particularly relating to an automobile steering pump. The automobile steering pump is mainly technically characterized in that a bearing, an oil seal, a thickened front oil distribution disk, a rotor and a black cover are sequentially arranged on a principal shaft of the steering shaft; a compression spring is installed between the front oil distribution disk and the inner wall of the pump body; a vane is installed in the vane groove of the rotor; and a stator is fixed inside the pump body. The automobile steering pump has the good effects that the thicknesses of the front oil distribution disk and the back oil distribution disk are increased, the back oil distribution disk and the back cover are combined into a whole, and that the compression spring is moved forward between the front oil distribution disk and the shell, thus avoiding the transformation of the front and the back oil distribution disks caused by high temperature. Meanwhile, the automobile steering pump reduces component parts, reduces production cost and improves product quality and is prolonged in service life.
Description
Technical field
The utility model belongs to the pump of the transferring oil that seal arrangement is arranged, a kind of specifically automobile steering pump.
Background technique
The structure of the spindle drive of existing steering pump of automobile is that main shaft one side is installed on the housing, on main shaft, blade is installed by stator, rotor, be positioned on the main shaft of blade both sides forward and backward oil distribution casing is installed, between back oil distribution casing and bonnet, holddown spring is being installed.The deficiency of this kind mechanism is forward and backward oil distribution casing easy deformation when temperature is high, has influenced the working life of steering pump.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of blade type steering pump spindle drive, back oil distribution casing in the existing steering pump and bonnet are merged into a part and thickening, simultaneously preceding oil distribution casing is also thickeied, overcome the problem that forward and backward oil distribution casing Yin Gaowen causes distortion, improve quality of product, prolonged the working life of steering pump.
The utility model is achieved in that blade type steering pump spindle drive, comprise the main shaft that is installed in the pump housing, be installed in the rotor on the main shaft, blade, forward and backward oil distribution casing, spring, the major technique feature is: preceding oil distribution casing 4, rotor 9, bonnet 7 that bearing 1, oil sealing 2, thickening are installed on steering pump main shaft 8 from outside to inside in proper order, between oil distribution casing and the pump housing inwall, blade 5 was installed in the blade groove of rotor 9 before holddown spring 3 was installed in, and stator 6 is fixed in the pump housing 10.
Compare with correlation technique, the beneficial effects of the utility model are the thickness increases with forward and backward oil distribution casing, back oil distribution casing and two parts of bonnet are merged into a part, and with holddown spring reach between preceding oil distribution casing and housing, overcome forward and backward oil distribution casing Yin Gaowen and caused the problem of distortion, and reduced part, reduced cost of production, improve quality of product, prolonged the working life of steering pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Shown in Figure 1, blade type steering pump spindle drive, preceding oil distribution casing 4, rotor 9, the bonnet 7 of bearing 1, oil sealing 2, thickening are installed on steering pump main shaft 8 from outside to inside in proper order, holddown spring 3 is installed between preceding oil distribution casing and the pump housing inwall, blade 5 is installed in the blade groove of rotor 9, and stator 6 is fixed in the pump housing 10.
The utility model is to improve realization on the basis of prior art scheme. In order to overcome forward and backward joining Food tray high temperature holds yielding problem, with the enlarged in thickness of front and back oil distribution casing, and 2 times of nearly original thickness. For conserve space, bonnet and two parts of rear oil distribution casing are united two into one, reduced the quantity of part. With The time, the position of holddown spring is adjusted at the front end of front oil distribution casing. Structure stable and reliable operation after the improvement, Forward and backward food tray is difficult for the problem of deforming when running into high temperature.
