Abstract
The utility model discloses an alloy power steering pump for the light vehicle. The pump is composed of an alloy pump body (1), a pump axis (2), alloy front oil distribution casing (3), a stator (4), a rotor (5), blades (6), an alloy pump cover (7) and a flux control valve assembly. The utility model is characterized in that: the pump axis is arranged in the alloy pump body through a sliding bearing, while the alloy front oil distribution casing (3) is elastically compressed on the stator (4) in advance through a compression spring (14). The pump axis is arranged in the alloy pump body through a sliding bearing and the sliding bearing is provided with a spiral oil groove so as to realize the requirement of bearing sliding lubrication.
Description
Technical field: what the utility model was related is a kind of auto parts and components, and what be specifically related to is a kind of improvement invention of aluminum alloy light-duty vehicle power steering pump.
Background technique: along with developing rapidly of world car industry, people require more and more higher to the performance of automobile and the travelling comfort and the price performance of driving.Therefore, for satisfying the requirement of people, in automobile steering system, used power steering pump to the motor turning sensitivity.If the flow of automobile power steering oil pump output can satisfy direction machine performance requirement when engine speed change, then oil pump just can effectively guarantee the stability of automobile steering system.And employed on the orthodox car power steering pump pump housing be rolling bearing, therefore often reach and can not satisfy direction machine performance requirement.In the prior art, transition curve between stator major diameter and minor axis, begin most is that employing waits deceleration curves such as acceleration, be easy to generate hard impact according to this transition curve, just velocity variations is impacted, in order to address this is that, afterwards curve of equal velocity was changed into the sine and cosine curve, though this transition curve has solved the problem of hard impact, but soft impact does not solve, be similarly the problem that solves soft impact, adopted Archimedes's transition curve again, but failed to solve simultaneously the technical problem of hard impact and soft impact.In order to satisfy the requirement of people to the automobile steering system cost performance, each producer all constantly employ new technology, new material, new process enhance product performance and reduce cost, and the weight that reduces auto parts and components has material impact to automobile energy-conservation, and realistic meaning is more arranged under the situation of current energy scarcity.
Summary of the invention: technical problem underlying to be solved by this invention is the rolling bearing that removes on the orthodox car power steering pump pump housing, employing has the sliding bearing of oil groove, satisfying direction machine performance requirement, and can separate the determinant transition curve and produce hard technical problem of impacting with soft impact.In order to achieve the above object, the utility model adopts following technological scheme to realize: the aluminium alloy power steering pump that this kind light-duty vehicle is used, this pump by the aluminum alloy pump housing, pump shaft, aluminum alloy before oil distribution casing, stator, rotor, blade, aluminum alloy pump cover, flow control valve assembly etc. form, it is characterized in that described pump shaft is installed in the aluminum alloy pump housing by sliding bearing, the elasticity prestressing that oil distribution casing utilizes holddown spring before described is on stator, and the transition curve between described stator minor axis and the major diameter adopts equation of higher degree curve.Described sliding bearing is provided with the screw type oil groove.Described pump cover is provided with the hole, and an end of described pump shaft stretches in this hole.Transition curve between described stator minor axis and the major diameter adopts the quintic equation curve.
The present invention has tangible advantage and useful effect compared with prior art, in configuration aspects: be installed in the pump housing by sliding bearing by pump shaft, and this sliding bearing has the screw type oil groove, can realize the moving lubricated requirement of bearing; Be processed with bearing hole on the pump cover,, do not have independent bearing as sliding bearing usefulness; Therefore save sliding bearing, needle bearing etc., thereby simplified the structure, reduced product cost, effectively reduced noise; Transition curve between stator minor axis and the major diameter adopts quintic equation, has avoided impact, makes the movement velocity of blade steady, and acceleration change is mild; The pump housing, pump cover, oil distribution casing, guiding valve all adopt the high-strength abrasion-proof aluminum alloy, compare weight saving 50% with traditional discharge capacity and pressure power steering oil pump; Flow control valve adopts flow, and the decline type makes motor turning more steady with the rotating speed increase.
Description of drawings: the utility model has following accompanying drawing:
Fig. 1 is the utility model structure sectional view.
Embodiment: accompanying drawing has been represented structure of the present utility model and embodiment, further describes the relevant details and the working principle of its structure below more in conjunction with the accompanying drawings.The aluminium alloy power steering pump that this kind light-duty vehicle is used, it by the aluminum alloy pump housing 1, pump shaft 2, aluminum alloy before oil distribution casing 3, stator 4, rotor 5, blade 6, aluminum alloy pump cover 7, flow control valve assembly etc. form.Described pump shaft 2 is installed in the aluminum alloy pump housing by sliding bearing 8, and described preceding oil distribution casing 3 utilizes the elasticity prestressing of holddown spring 14 on stator 4.Described sliding bearing 8 is provided with screw type oil groove (not marking among this oil groove figure).Described pump cover is provided with the hole, and an end of described pump shaft stretches in this hole.Transition curve between described stator minor axis and the major diameter adopts quintic equation.Motor drives pump shaft 2 and rotates, pump shaft 2 connects drive rotor 5 by spline and rotates, blade 6 in the rotor is along with rotor rotation, realize blade 6 radial motions simultaneously by specific curves on the stator 4, press oil thereby realize inhaling, realize that by flow control valve flow keeps relative stability with rotation speed change again.
