Description
Technical field
The utility model relates to a kind of support bushing device for deflector.
Background technology
Along with the development of automotive market, people require also more and more higher to the traveling comfort of manned vehicle, and manned vehicle C-EPS steering swivel system many employings mechanical gear tooth bar deflector at present, this steering gear rack generally adopts rack support lining to support on right side.When chaufeur beats direction to the left or to the right, tooth bar two ends can be subject to the diametral load effect from pull bar different directions, and thus tooth bar produces swing.When commutation hour rack Impact direction changes, swaying direction also can change thereupon, when tooth bar swings to another direction from a direction, swinging distance is larger, if rack support bushing inner diameter and tooth bar tolerance clearance larger, the distance that tooth bar swings also will be larger, and abnormal sound phenomenon during commutation will be more obvious.And when tooth bar coordinate with support bushing comparatively tightly, grease memory space inadequate just there will be the abnormal sound phenomenon that rubs.If therefore support bushing structure design is unreasonable, when automobile in-place can be made to play direction, commutation to the left or to the right, produce abnormal sound, generally show as more dull, that sound is larger " Simple-minded Simple-minded " sound or resilience of letting go after beating direction to side " rub-a-dub " a sound; If the bad automobile that also can make of the lubricant effect of lining is when direction is beaten in any position to the left or to the right, occur nonmetallic friction abnormal sound, this sound can be delivered to operator's compartment by vehicle body and deflector itself, and chaufeur is had the fidgets uneasiness.
At present some manual steering gear support bushing is designed to internal diameter and tooth bar and is fitted tightly by the enclasping force that O shape is enclosed and both can ensure that Zero clearance coordinates, backlash compensation can be provided again after liner wear, the gap of further elimination bushing inner diameter and tooth bar, there is higher wear-resisting persistence, but usual this kind of lining is because of complicated structure, its manufacturing cost such as mould and material can be very high, is usually used in front axle load heavier or on the harsher car load of abnormal sound requirement.
Utility model content
The purpose of this utility model is to provide a kind of support bushing device for deflector, solves the existing support bushing device for deflector or manufacturing cost is higher, or there is the problem turning to abnormal sound.
The technical scheme in the invention for solving the technical problem is: a kind of support bushing device for deflector, comprise the support bushing with steering gear rack adaptation, also comprise the support ring with steering gear rack adaptation, described support bushing is fixed in the rear side housing of manual steering gear by limiting stopper, described support ring is crossed to win to coordinate and is fitted in the front side housing of manual steering gear, and described support ring and steering gear rack Zero clearance coordinate; The cylinder body of described support ring and press-in front side housing cooperatively interacts, the left and right displacement of restriction support ring.
In order to provide a space storing lining grease, avoid support bushing and tooth bar dry friction to produce abnormal sound, described support bushing inwall is provided with one group for storing the groove of lining grease.
Preferably, between described two adjacent grooves, form boss, described boss is provided with one group of circular concave point.
In order to better avoid support bushing to accept rear end float misalignment, described support bushing lateral wall is provided with four boss structures for clamping with rear side housing.
In order to make support bushing more easily be pressed on rear side of deflector in housing, the support bushing lateral wall of described boss structure both sides is distributed with one group of zigzag structure.
Preferably, the material of described support ring is the resilient nonmetallic material that friction coefficient is low, resistance to abrasion is good
The utility model beneficial effect: tooth bar is through the dual support of support bushing and support ring, when tooth bar is subject to the radial reaction force of pull bar applying, the hunting range of tooth bar reduces, and then can ensure can not produce abnormal sound when playing direction commutation in operator's compartment, makes chaufeur mood keep happy.Tooth bar hunting range reduces, and can reduce the degree of wear to lining, thus elongated component service life, reduce car load maintenance cost.Support bushing is designed with groove and concave point structure, is formed and larger deposit fat space, make tooth bar smooth and easy slip can not produce friction abnormal sound.
The utility model effectively can solve the existing support bushing device for deflector or manufacturing cost is higher, or there is the problem turning to abnormal sound, and structure is simple, reliable, can be widely used in the support bushing device field of deflector.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
