Description

A kind of oil inlet passage of steering pump of automobile and steering pump of automobile

Technical field

The present invention relates to steering pump of automobile field, particularly relate to a kind of oil inlet passage of steering pump of automobile.

Background technique

Thrust plate and housing are two important parts on steering pump, and they and cam ring, pressure plate, bonnet form an oil inlet passage jointly, the inside flowing be low pressure oil; High pressure oil flows to housing bottom by the filler opening on thrust plate, and in order to separate high and low force feed region, prior art is that the mode fitted tightly by thrust plate and the large plane of housing plays seal action.Its deficiency is that thrust plate thinner thickness, intensity are lower, is easily out of shape under high pressure-temperature, and make thrust plate, wearing and tearing aggravation between pressure plate and rotor, have noise and produce, the particle come off that weares and teares can cause card valve, causes steering pump of automobile to lose efficacy; The planarity requirements of thrust plate bottom surface is quite high, and needs phosphorating treatment, and processing cost is high; Oil inlet passage region is comparatively large, and oil circuit is tortuous, and energy loss is serious, and oil-feed efficiency is low, easily under high speed conditions, produces air pocket noise.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of oil inlet passage of steering pump of automobile, can improve oil-feed efficiency, reduces noise, increases the intensity of thrust plate, improves reliability and the working life of steering pump.

For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: the oil inlet passage providing a kind of steering pump of automobile, comprise housing, thrust plate, filler opening, described enclosure interior is provided with supporting surface, described supporting surface is provided with the first oil-feed tank, described first oil-feed tank is U-shaped, described thrust plate is arranged on above supporting surface, thrust plate is provided with the second oil-feed tank, second oil-feed tank is corresponding with the first oil-feed tank arranges formation oil inlet passage, described oil inlet passage one end is connected with filler opening, described thrust plate external diameter is provided with O type circle.

In a preferred embodiment of the present invention, described first oil-feed tank, the second oil-feed tank are by some sections of circular arcs and rectilinear(-al).

In a preferred embodiment of the present invention, described first oil-feed tank one end offers blind hole, and described second oil-feed tank one end offers through hole, is connected with locating stud between described blind hole and through hole.

In a preferred embodiment of the present invention, described thrust plate is provided with oil outlet.

The invention has the beneficial effects as follows: the present invention together form oil inlet passage by the first oil-feed tank of housing and the second oil-feed tank of thrust plate, avoid original housing high pressure oil region in the problem of enclosure interior not easy cleaning, improve turbidity test; Add thickness and the intensity of thrust plate, thus reduce inner body wearing and tearing, improve the reliability of steering pump; Instead of plane gluing, sealing with the sealing of O type circle simultaneously, improve sealing effect, improve the efficiency of steering pump.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.

As Figure 1-3, the embodiment of the present invention comprises:

A kind of oil inlet passage of steering pump of automobile, comprise housing 1, thrust plate 2, filler opening 3, described housing 1 inside is provided with supporting surface 4, described supporting surface 4 is provided with the first oil-feed tank 5, described first oil-feed tank 5 is U-shaped, and described thrust plate 2 is arranged on above supporting surface 4, thrust plate 2 is provided with the second oil-feed tank 6, second oil-feed tank 6 is corresponding with the first oil-feed tank 5 arranges formation oil inlet passage, and described oil inlet passage one end is connected with filler opening 3, and described thrust plate 2 external diameter is provided with O type circle 9.

As shown in Figure 4, described first oil-feed tank 5, second oil-feed tank 6 is by some sections of circular arcs and rectilinear(-al), and the first oil-feed tank 5, second oil-feed tank 6 shape, size, position consistency, both together form oil inlet passage, and are connected with filler opening 3.

Described thrust plate 2 is provided with oil outlet 11, and low pressure oil enters from filler opening 3, by oil inlet passage, finally enters into by the oil outlet 11 on thrust plate 2 active chamber be made up of rotor, cam ring and blade.The O type circle 9 of thrust plate 2 external diameter can prevent low pressure oil from leaking, and instead of plane gluing, sealing, improves sealing effect.

Described first oil-feed tank 5 one end offers blind hole 7, described second oil-feed tank 6 one end offers through hole 8, locating stud 10 is connected with between described blind hole 7 and through hole 8, as shown in Figure 5, the mounting type of this single-locating pin 10 eliminates the key on the supporting surface 4 of procapsid 1 and the groove on thrust plate 2, the substitute is the blind hole 7 on housing 1, the through hole 8 on thrust plate 2 and locating stud 10, this greatly reduces the cost of manufacturing, and can be connected with housing 1 correspondence by thrust plate 2 effective and rapidly; Having the leading role of locating stud 10 when press-fiting, being easily correctly press-fit into place by thrust plate 2, the strict guarantee installation precision of swivel assembly, improves and turns to pump performance and working life; Simultaneously because the position of positioning pin hole can not affect the processing of the supporting surface 4 of housing 1, therefore on housing 1, the selectable location of positioning pin hole is more, is not limited to.

When steering pump work time, first low pressure oil enters the oil inlet passage of housing 1 and thrust plate 2 formation by return tube, then enter into by the oil outlet 11 of thrust plate 2 active chamber be made up of rotor, cam ring and blade, the high pressure oil formed enters into high pressure oil region by the oil outlet on cam ring, finally discharge from high pressure oil outlet port, the oil suction chamber of such formation is smooth smooth and easy, small volume, energy loss is few, oil-feed efficiency is high, the intensity of thrust plate is high simultaneously, is out of shape little, can improves the reliability of steering pump and the durability of part.

The present invention also provides a kind of steering pump of automobile, and described steering pump body interior is provided with this oil inlet passage, improves the efficiency of steering pump.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
