Abstract
The utility model discloses a novel steering gear structure. A rack inside a steering gear is fixed inside a shell body of the steering gear through a rack lining. An elastic component is arranged between the rack lining and the shell body of the steering gear. On one hand, the elastic component plays an auxiliary supporting role, when the pavement conditions are very poor, most acting force not perpendicular to the axis of the rack can be corrected, the stress situation of an original rack lining is improved through the action force, and the abrasion speed is lowered; on the other hand, the elastic component presses an inner ring on the rack to enable the inner ring to be in zero clearance fit with the rack, so that even when the inner ring is abraded ceaselessly, the inner ring and the rack can be attached to each other all the time through the elasticity of a strap, the clearance is eliminated, and the novel steering gear structure has the function of an automatic adjusting mechanism.
Description
Technical field
The utility model relates to automobile steering system, relates in particular to diverter structure.
Background technology
As shown in Figure 1, the supporting base major part adopts the non-metallic bushings structure to the rack and pinion steering gear structure at present.Although bush structure is various informative, similar generally, also have common characteristics to wear and tear exactly the change of back bush internal diameter greatly, become large with the tolerance clearance of tooth bar.
The rack bush of deflector is the support of steering gear rack, when deflector is worked, because lining and tooth bar are the relations of free-running fit, so lining is equivalent to the plain bearing of tooth bar.Because the Comparision of deflector is frequent, after tooth bar and lining friction, liner wear, so constantly become large with the gap of tooth bar.Simultaneously, because the force direction that is subject to of steering gear rack is not perpendicular to the tooth bar section, this makes tooth bar except axially being drawn, pressure, also has the component perpendicular to rack axis, this component is born by rack bush fully, and this component effect has also caused the accelerated wear test of rack bush.When the wearing and tearing post gap is greater than to a certain degree, when vehicle is subject to road shocks, impulsive force is passed to the tooth bar of deflector through wheel, so produce to impact at gap location, sends noise.Especially when Vehicle Driving Cycle during on poor road surface, when vehicle is carried out to steering operation, impulsive noise especially easily sends, and this can bring very large puzzlement to chaufeur, has affected the use level of comfort of vehicle integral body.
The utility model content
Technical problem to be solved in the utility model is to realize that a kind of noise is low, and little diverter structure weares and teares.
To achieve these goals, the technical solution adopted in the utility model is: a kind of novel steering device structure, the tooth bar in deflector is fixed in steering gear housing by rack bush, between described rack bush and steering gear housing, elastic element is installed.
Described elastic element is the loop configuration surrounded by the waveform lath.
The utility model has the advantage of by increasing elastic element, on the one hand, play the effect of supplemental support, can revise when running into the very poor situation of condition of road surface the application force that great majority are not orthogonal to rack axis, the result of effect is exactly the stressing conditions that has improved original rack bush, has reduced the rate of wear; On the other hand, the elasticity original paper compresses inner ring and tooth bar, keeps Zero clearance to coordinate, even work as inner ring, constantly weares and teares, and also can rely on the elasticity of hoop, remains inner ring and tooth bar laminating, eliminates gap, and the result of effect just is equal to a clearance self-regulating complete machine structure.
The accompanying drawing explanation
Below the content of every width accompanying drawing expression in the utility model specification sheets and the mark in figure are briefly described:
Fig. 1 is conventional steering gear bush constructional drawing;
Fig. 2 is the utility model steering gear bush constructional drawing;
Fig. 3 is elastic element structure schematic diagram shown in Fig. 1;
Mark in above-mentioned figure is: 1, steering gear housing; 2, elastic element; 3, rack bush; 4, tooth bar.
The specific embodiment
Known referring to Fig. 2, novel steering device structure is mainly to increase chip architecture of the spring on the original supporting construction of deflector, the elastic element 2 of an annular is installed between rack bush 3 and steering gear housing 1, tooth bar 4 is fixed in steering gear housing 1 by rack bush 3, as shown in Figure 3, this elastic element 2 is the loop configuration that surrounded by the waveform laths of metal.Like this, after rack bush 3 wearing and tearing, elastic element 2 resiliences, can guarantee that rack bush 3 inner rings and tooth bar 4 still are the force fit state.
Claims (2)
1. a novel steering device structure, the tooth bar (4) in deflector is fixed in steering gear housing (1) by rack bush (3), it is characterized in that: between described rack bush (3) and steering gear housing (1), elastic element (2) is installed.
2. novel steering device structure according to claim 1, it is characterized in that: described elastic element (2) is the loop configuration surrounded by the waveform lath.
