Description
Technical field
The invention belongs to automobile mechanical steering gear field, specifically refer to that a kind of automobile mechanical that prevents abnormal sound turns toDevice.
Background technology
In manual steering gear, rack and pinion axle intermediate gap adjusting device by supporting base, supporting base pad,Supporting base external cylindrical surface O RunddichtringO, helical spring, adjustment plug screw, locking nut composition. Supporting seat cushionSheet is arranged on supporting base, supports tooth bar, and O RunddichtringO, Neng Gouhuan are installed on supporting base external cylindrical surfaceRush on tooth bar and impact, reduce noise and increase feel. Helical spring can compensate due to rack-and-pinion wearing and tearingThe gap value increasing, ensures steering gear performance.
Show the concrete structure of manual steering gear as shown in Figure 1, the Mesh Clearance Adjustment of gear shaft 1 and tooth bar 2Device is by supporting base 3, supporting base pad 4, O RunddichtringO 5, helical spring 6, adjustment plug screw 7, lockJack panel 8 forms. Supporting base pad 4 is arranged on supporting base 2 under the effect of helical spring 6 to supportTooth bar 2, the external cylindrical surface on supporting base 3 is provided with O RunddichtringO 5, can cushion rushing on tooth bar 2Hit, reduce noise and increase feel. Helical spring 6 can compensate due to rack-and-pinion wearing and tearing increase betweenGap amount, ensures steering gear performance. Between supporting base 3 and adjustment plug screw 7, only have one to adjust spring 6, whenCross while jolting road surface, tooth bar can impact, and causes supporting base 3 to move outward, adjusts plug screw with supporting base7 the end face generation abnormal sound that bumps.
Served as while jolting road surface, tooth bar can impact under the effect of external force load, causes supporting base outwardMobile, adjust plug screw with supporting base and bump. Because both metals, so the sound sending while shockSignal to noise ratio is clearer and more melodious, and people's ear can distinguish easily, has reduced the NVH performance of car load.
Summary of the invention
The object of the invention is by existing manual steering gear is proposed to improve technical scheme, by this technologyScheme can reduce rack support piece and adjust plug screw and send larger noise while bumping.
The present invention is achieved by the following technical solutions:
Prevent an automobile mechanical steering gear for abnormal sound, include supporting base, helical spring and adjust plug screw;
Described supporting base is cylindrical hollow structure, and its one end is circular arc concave structure, presses with the tooth bar face of cylinderTight fit; Described circular arc concave surface is provided with the supporting base pad of being made up of high-abrasive material; Described supporting base settingIn steering gear housing;
The other end of described supporting base is disposed with helical spring and adjusts plug screw; Described helical spring settingIn the hollow structure of supporting base, supporting base is withstood in one end, and the other end contacts with adjustment plug screw inner surface;
Described adjustment plug screw contacts helical spring one end and is provided with hollow structure; Establish described helical spring one endBe placed in this hollow structure;
On the periphery of described supporting base, be provided with at least one circle groove; In described groove, be provided with the sealing of O typeCircle;
Described supporting base is provided with at least one butterfly near adjusting the end face of plug screw one end and adjusting between plug screwShape spring.
The hollow structure internal diameter difference of described supporting base, wherein the internal diameter of nearly circular arc concave surface be less than the other end inFootpath.
Height under described each butterfly spring free state is 1mm.
The shape of described supporting base pad matches with the circular arc concave structure of supporting base, and in circular arc concave bottom portionBe provided with projection, the hollow space internal diameter of this projection and supporting base adapts.
The outer end of described adjustment plug screw is also provided with check bolt.
The invention has the beneficial effects as follows:
Between supporting base and supporting base adjustment plug screw, except the helical spring of briquetting, increase a butterflySpring, thus avoid supporting base and adjusted plug screw and collide, change relative motion into butterfly spring selfDistortion, has avoided the generation of abnormal sound, has improved the NVH performance of car load.

Detailed description of the invention
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 be to the technology of the present invention sideThe restriction of case.
As shown in Figures 2 to 6, prevent the automobile mechanical steering gear of abnormal sound, include supporting base 3, spiralSpring 6 and adjustment plug screw 7;
Described supporting base 3 is cylindrical hollow structure, and its one end is circular arc concave structure, with tooth bar 2 cylindersFace compression fit; Described circular arc concave surface is provided with the supporting base pad 4 of being made up of high-abrasive material; Described supportingSeat 3 is arranged in steering gear housing 9;
The other end of described supporting base 3 is disposed with helical spring 6 and adjusts plug screw 7; Described spiral bulletSpring 6 is arranged in the hollow structure of supporting base 3, and supporting base 3 is withstood in one end, the other end and adjustment plug screw 7Inner surface contact;
One end that described adjustment plug screw 7 contacts helical spring 6 is provided with hollow structure; Described helical spring 6One end is arranged in this hollow structure; The outer end of described adjustment plug screw 7 is also provided with check bolt 8.
On the periphery of described supporting base 3, be provided with at least one circle groove; In described groove, be provided with O type closeSeal 5;
Described supporting base 3 is provided with at least one near adjusting the end face of plug screw one end and adjusting between plug screw 7Butterfly spring 10; Described butterfly spring is hollow structure, and helical spring penetrates hollow structure.
The hollow structure internal diameter difference of described supporting base, wherein the internal diameter of nearly circular arc concave surface be less than the other end inFootpath.
The shape of described supporting base pad matches with the circular arc concave structure of supporting base, and in circular arc concave bottom portionBe provided with projection, the hollow space internal diameter of this projection and supporting base adapts.
Specifically (contact with supporting base collision with the inner face of adjusting plug screw 7 at the supporting base 3 of steering gearFace) between place a butterfly spring 10, the technical parameter of this butterfly spring is: under free state highly for 1mm,Butterfly reed is thick is 0.4mm, and material is 65Mn through Quenching Treatment. Butterfly spring in being under pressure, selfAxial bounce-back support force is provided when highly reducing. When car load is through jolting road surface or while turning to, toothWheel shaft 1 and tooth bar 2 be subject to impact make supporting base and adjust plug screw collide trend time, due to depositing of butterfly springAt, supporting base with adjust plug screw and can directly not collide, but with the support of a kind of butterfly spring self relative deformationMode has completely cut off supporting base and has adjusted the collision between plug screw, has reduced noise in a kind of soft mode.
