Abstract
The utility model discloses a kind of steering gear rack lining, comprise cylindric bush body, some open slots are evenly distributed with in one end circumference of described bush body, bush body inwall between adjacent two open slots is provided with the oil resevoir of bar shaped along bush body axis direction, is arranged with O type circle in the periphery of described bush body.The utility model can reduce the friction force between tooth bar and rack bush, ensures tooth bar smooth movement.
Description
Technical field
The utility model relates to wheel steering system parts, is specifically related to a kind of rack bush of pinion and-rack manual steering gear.
Background technology
The rack bush of pinion and-rack manual steering gear, be assemblied in steering gear housing inside, outer end is fixed by back-up ring, and tooth bar passes in the middle of rack bush.Rack bush is played a supporting role to tooth bar, ensures tooth bar smooth movement, and then completes turning to of automobile.Rack bush receives the radial pressure and axial friction that tooth bar gives in this motion process.
As shown in Figure 1, existing bush body 1 is integral type structure, and structure is simple, and lubricant effect is poor, easily causes tooth bar and rack bush dry friction, produce and turn to friction abnormal sound, or rack bush is excessively abraded, and produces and turns to looseness abnormal sound.
Summary of the invention
The purpose of this utility model is to provide a kind of steering gear rack lining, to reduce the friction force between tooth bar and rack bush, ensures tooth bar smooth movement.
Steering gear rack lining described in the utility model, comprise cylindric bush body, some open slots are evenly distributed with in one end circumference of described bush body, bush body inwall between adjacent two open slots is provided with the oil resevoir of bar shaped along bush body axis direction, is arranged with O type circle in the periphery of described bush body.
Rack bush described in the utility model has the advantage that structure is simple, reliability is high, can reduce reverse thrust, promotes turning efficiency.Solve existing machinery steering assembly after high mileage, lack of lubrication between tooth bar and rack bush, and produce the problem turning to friction abnormal sound.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing rack bush;
Fig. 2 is three-dimensional view of the present utility model;
Fig. 3 is steering assembly assembling schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
Steering gear rack lining as shown in Figure 2, comprise cylindric bush body 1,12 road open slots 101 are evenly distributed with in one end circumference of described bush body 1, bush body inwall between adjacent two open slots is provided with the oil resevoir 102 of bar shaped along bush body axis direction, the inwall of described bush body 1 is furnished with 12 road oil resevoirs altogether.O type circle 103 is arranged with in the periphery of described bush body 1.
Steering assembly assembling schematic diagram as shown in Figure 3, first in the open slot 101 and oil resevoir 102 of above-mentioned bush body, proper lubrication grease is full of, again bush body 1 is pressed into it from one end of steering gear housing 2 inner, then with back-up ring 3, rack bush is fixed on steering gear housing inside, finally tooth bar 4 is passed from rack bush inside.Wherein, bush body 1 upper shed groove be arranged so that bush body self has certain elasticity, can automatic compensation gap.The oil resevoir of bar shaped ensure that oil reserve, and the lubricating grease be contained in oil resevoir reduces the friction force between tooth bar 4 and bush body 1, reduces friction abnormal sound risk, reduces the reverse thrust of manual steering gear assembly, improve turning efficiency.Described O type circle 103 is compressed between bush body 1 and steering gear housing 2, and when rack bush is subject to the radial pressure that tooth bar gives, described O type circle can absorption portion pressure, reduces the wearing and tearing of rack bush, avoid generation to turn to looseness abnormal sound.
Claims (1)
1. a steering gear rack lining, comprise cylindric bush body (1), some open slots (101) are evenly distributed with in one end circumference of described bush body, it is characterized in that: the oil resevoir (102) the bush body inwall between adjacent two open slots being provided with bar shaped along bush body axis direction, is arranged with O type circle (103) in the periphery of described bush body.
