Abstract
The invention relates to a compressing adjusting mechanism for a mechanical steering gear for an automobile. The compressing adjusting mechanism comprises a supporting base, a spiral spring, an adjusting screw plug and a belleville spring. The supporting base is of a cylindrical hollow structure, and one end of the supporting base is of a circular arc concave face structure and is in compressing fit with the cylindrical surface of a rack. A wear-resistant material layer is arranged on the circular arc concave face. The supporting base is arranged inside a steering gear shell. The other end of the supporting base is sequentially provided with the spiral spring, the adjusting screw plug, the belleville spring and a lock bolt. The spiral spring is arranged inside the hollow structure of the supporting base, one end of the spiral spring abuts against the supporting base, and the other end of the spiral spring makes contact with the inner surface of the adjusting screw plug. Due to the facts that the compressing adjusting mechanism comprises the belleville spring and the adjusting screw plug with an O-type ring, and the belleville spring and the adjusting screw plug are assembled in an overlaid and combined mode, a meshed interval between a gear and the rack is compensated, and meanwhile the impact sound generated when the rigidity impact between the supporting base and the adjusting screw plug occurs on a bumping road is eliminated.

Described adjustment plug screw contacts helical spring one end and is provided with hollow structure; Described coil spring one end is arranged in this hollow structure;
Described belleville spring is arranged at the nearly adjustment screw plunger end of supporting base and adjusts between screw plunger end, and coil spring passes from its hollow space.
On the periphery of described supporting base, be provided with at least one circle groove; In described groove, be provided with O type circle.
The hollow structure internal diameter difference of described supporting base, wherein the internal diameter of nearly circular arc concave surface is less than the internal diameter of the other end.
Described adjustment plug screw is provided with on an end face of hollow structure and is provided with a circle groove structure; In described groove structure, be provided with O type circle; One end in contact of described O type circle and belleville spring.
Described belleville spring is at least one group, passes coil spring with series system, and take coil spring as inner guiding post.
Described belleville spring be shaped as circular cone dish ring-type, inner ring is greater than helical spring external diameter through coil spring and size, outer ring size is less than or equal to supporting base external diameter.
The outer end of described adjustment plug screw is also provided with lock bolt.
The invention has the beneficial effects as follows:
The present invention utilizes belleville spring and O type circle to have automatic elastic compensating function, eliminate the gap producing because of abrased gear tooth bar, the combination of belleville spring and O type circle simultaneously, there is the strike note that supporting base produces with adjusting the rigid collision of plug screw in the road of having avoided jolting.

The specific embodiment
Describe by the following examples technical scheme of the present invention in detail, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
The vocabulary of terms that may relate in technical solution of the present invention:
Manual steering gear: inner without Hydraulic Elements, pure mechanical part combination, will become the power that promotes tyre rotation from the torque axis of bearing circle and tubing string.
Hydraulic steering gear: receiving the pressure producing from the hydraulic oil of power steerig pump, is the power that promotes tyre rotation by pressure transmission by hydraulic unit.
Electric steering column: increased the driving of motor compared with mechanical tubing string, coordinated speed reduction driving mechanism for power to realize the effect that moment increases.
Power steerig pump: device is on driving engine, with belt wheel.Passive by engine drive, band wheel drive inner vanes rotary pump oil, exports to hydraulic steering gear by pipeline by hydraulic oil.
Steering gear shaft: be positioned at deflector input end, coordinate the transmission that realizable force torque conversion is power with the inner tooth bar processing of deflector tooth profile of tooth end.
Deflector pull bar: be assemblied in steering gear rack end, tire and the inner tooth bar of deflector are connected, work to transmit promotion tire force.
In technical scheme of the present invention, the structure of automobile mechanical deflector does not change, and is prior art scheme.
As shown in Figure 1 to Figure 3, automobile mechanical deflector compress that adjusting mechanism comprises supporting base 1 and O type circle 11 thereof, coil spring 2, adjusts plug screw 3 and O type circle 31 thereof, belleville spring 5, lock bolt 4.
Supporting base 1 is cylindric, end is designed to circular arc concave surface 12, itself and tooth bar face of cylinder force fit, concave panel is provided with wear-resistant material layer 121, and described supporting base circumferencial direction is provided with O type circle 11, coordinates with steering gear housing inside face, the effect of described supporting base is that gear 6 and tooth bar 7 are compressed, described supporting base inside is hollow structure 13, the hollow structure internal diameter difference of supporting base, and wherein the internal diameter of nearly circular arc concave surface is less than the internal diameter of the other end.Be provided with coil spring 2, coil spring 2 one end are contained in supporting base circular-arc bottom face 14.The other end contacts with plug screw 3 inside faces 31, when assembling, plug screw 3 is crossed together the face of cylinder 61 that coil spring 2 is close to 121 layers of supporting base spill high-abrasive materials tooth bar 6, described adjustment plug screw is also hollow structure 32, hollow position assembling coil spring 2, the end face of hollow structure 32 arranges circular groove 321, assembling O type circle 322, urgent with steering gear housing before, assemble some belleville springs 2 at supporting base planar end surface, adopt the folded method 21 of series connection to assemble.
In order to solve the problem of clashing into abnormal sound, the invention provides belleville spring and the O type circle of adjusting plug screw surface, belleville spring be shaped as circular cone dish ring-type, inner ring passes through coil spring, size Selection is greater than helical spring external diameter, and outer ring size is less than or equal to supporting base external diameter, and described belleville spring 4 adopts stack combinations assembling, due to surface friction drag effect, the effect of impact-absorbing and dissipation energy is more remarkable.
In use rack of steering is in continuous wearing and tearing for vehicle, and constantly amplify in the gap that both can engage, and the clamping stroke of belleville spring, for stack quantity sum, has automatic elastic compensating function, can make up the compensation of wearing and tearing post gap.Because disk spring is annular, power is that concentric manner is concentrated transmission, can play the effect of powerful buffering and damping simultaneously.
Adjust screw plunger end and increased O shape circle, O type circle contacts with belleville spring face, and O type circle has high abrasion, also has automatic elastic compensating function after wearing and tearing, so utilize the combination of belleville spring and O type circle, can avoid rack supporting seat and adjust collision between plug screw producing abnormal sound.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
