Abstract
The utility model discloses a cartridge type cross shaft coupling, composed of cylindrical housing, wherein square holes which are mutually perpendicular are arranged on the two sides of the cylindrical housing, and the square holes form a staggered (not in a plane) cross, so as to connect an electric shaft of an electric vehicle hydraulic power steering pump with an oil pump shaft. The utility model is suitable for the electric vehicle hydraulic power steering pump.
Description
Technical field
But the utility model relates to the barrel type cross coupler that a kind of electronic automobile hydraulic steering pump is used, and belongs to the manufacturing technology field of motor turning servomechanism.
Background technique
Along with the develop rapidly of automotive industry, people are to the travelling comfort of driving, the raising of security requirement, but the performance of electronic automobile hydraulic steering system is also had higher requirement.But existing electronic automobile hydraulic steering system adopts cake formula cross coupler that the direct current generator and the oil pump of electronic automobile hydraulic steering pump are associated in together, is difficult to guarantee both coaxalitys in making installation process.The axial dimension of cake formula cross coupler is little, and very near to the distance that makes motor and oil pump, rigidity is strong during rotation, and noise is big.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, and using effect is good, can effectively reduce noise, but guarantees the barrel type cross coupler of electronic automobile hydraulic steering pump stable operation.
In order to achieve the above object, the utility model has mainly adopted following technological scheme to realize.But the barrel type cross coupler that the utility model is used for the electronic automobile hydraulic steering pump by cylindrical housings with based on cylindrical housings, is respectively equipped with orthogonal square hole (seeing Fig. 1,2,3) in the cylindrical housings both sides.Described square hole forms the cross of dislocation (not in same one side), but the motor and the oil pump of electronic automobile hydraulic steering pump is associated in (see figure 4) together.
The utility model compared with prior art, have following outstanding advantage and good effect: (1) has increased the axial distance of motor and oil pump, it is flexible that diaxon when rotation produced, rigidity reduces, and reduces noise.(2) barrel type cross coupler has reduced because the accuracy of manufacturing of coupling itself produces noise than cake formula cross coupler accuracy of manufacturing height.The cylindrical of stator is positive round structure, and the centre is provided with pressing chamber, has reduced the output fluid pulsation of boosting pump for car steering, has reduced the noise of pump.
But the utility model is applicable to the electronic automobile hydraulic steering pump.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Description of drawings
Fig. 1 is an overall structure sectional view of the present utility model;
Fig. 2 is that A shown in Figure 1 is to view;
Fig. 3 is that B shown in Figure 1 is to view;
Fig. 4 is for being effect sectional view of the present utility model;
Embodiment
Shown in Fig. 1,2 and 3, formed by cylindrical housings 1, on cylindrical housings 1, be respectively equipped with orthogonal square hole 2,3 in the both sides of cylindrical housings 1.Described two square holes form the cross of dislocation (not in same one side).
As shown in Figure 4, but the utility model the motor reel 5 and the oil pump shaft 4 of electronic automobile hydraulic steering pump is associated in together.
But the utility model is applicable to the electronic automobile hydraulic steering pump.
Claims (2)
1, a kind of barrel type cross coupler is made up of cylindrical housings (1), it is characterized in that being respectively equipped with orthogonal square hole (2), (3) in the both sides of cylindrical housings (1).
2, barrel type cross coupler according to claim 1 is characterized in that described square hole (2), (3) form the cross of dislocation.
