Abstract
The invention discloses a rack and gear meshing clearance adjusting mechanism for an automobile steering device. The rack and gear meshing clearance adjusting mechanism comprises a rack and a gear; a clearance adjusting ring hole which is matched with the rack in a sliding way is an eccentric hole; a clearance adjusting ring is matched in a hole of a steering device casing in a sliding way; a conical groove perpendicular to an axis of the clearance adjusting ring is formed in the circumferential surface of the clearance adjusting ring; the conical groove is greater in groove opening and small in groove bottom; a threaded hole opposite to the groove bottom of the conical groove is formed in the steering device casing; an adjusting screw is matched with the threaded hole; a lug is arranged on the circumferential surface at one end of the clearance adjusting ring; the front side, the rear side and the left side of the lug are disconnected with the clearance adjusting ring; part of outer surface of the lug is higher than the outer circumferential surface of the clearance adjusting ring; and the lug higher than the circumferential surface of the clearance adjusting ring is matched with an annular slot in the hole wall of the steering device casing in a sliding way. The rack and gear meshing clearance adjusting mechanism disclosed by the invention has significant advantages of stable meshing clearance and no abnormal sound.
Description
Technical field:
The present invention relates to a kind of Automotive Steering Technology, particularly a kind of automobile steering gear rack and gear backlash guiding mechanism.
Background technology:
Existing clearance adjustment mechanism is formed by compressing the briquetting of tooth bar, spring, plug screw and hold-doun nut, owing to the length of the vibrating spring of vehicle can change, makes back lash unstable, causes that steering behaviour is deteriorated.
Summary of the invention:
It is an object of the invention to provide the stable a kind of automobile steering gear rack in a kind of wheel and rack back lash and gear backlash guiding mechanism.
The technical scheme is that a kind of automobile steering gear rack and gear backlash guiding mechanism, including rack and pinion, it is characterized in that: it is eccentric orfice that the gap slippery with tooth bar adjusts annular distance, in the sliding hole being assigned in steering gear housing of described gap adjustment ring, the side face of described gap adjustment ring is provided with and the cone tank of gap adjustment ring axis perpendicular, the notch of this cone tank is big and bottom land is little, described steering gear housing is provided with the screwed hole relative with the bottom land of described cone tank, adjust screw and this corresponding threaded holes, the side face of adjustment ring one end, described gap is provided with projection, before this projection, adjust ring body with left side and gap afterwards to be not attached to, the partial outer face of this projection is higher than the outer peripheral face of gap adjustment ring, should sliding higher than the projection of gap adjustment ring side face and the cannelure on steering gear housing hole wall join.The side face of gap adjustment ring is provided with the cannelure matched with O RunddichtringO, and this cannelure is relative with the cannelure on steering gear housing hole wall.
The present invention has the remarkable advantage that back lash is stable and has no abnormal sound compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is automobile steering gear rack of the present invention and gear backlash guiding mechanism front view, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the perspective view of gap adjustment ring.
Detailed description of the invention:
The technical scheme is that, gap adjustment ring 2 endoporus is eccentric orfice, this eccentric orfice is slidably fitted on the cylinder of tooth bar 1, the side face of gap adjustment ring is provided with the groove 6 with axis perpendicular, the notch of this groove is big and cone tank that bottom land is little, the side face of described gap adjustment ring is provided with and O-ring seals co-operating annular groove 7, the effect of this sealing ring is to avoid abnormal sound, the side face of adjustment ring outer end, gap is provided with projection 8, before this projection, adjust ring body with left side with gap afterwards to separate, this projection side face is higher than the side face of gap adjustment ring, the right side of this projection is inclined-plane, it is easy to gap adjust and housing bore assembling, this projection is slippery with the cannelure on housing bore, this projection can rotate in the cannelure of housing bore, but can not move axially, (referring to Fig. 3).Being provided with on housing and adjust screw and match screwed hole, this screwed hole is relative with the notch of the cone tank on the adjustment ring side face of gap.
Method and the principle of gap of the present invention adjustment are, the eccentric orfice being cased with the gap adjustment ring of O RunddichtringO is enclosed within tooth bar and pushes it in the hole of housing, make in the cannelure that projection enters on housing bore, make the conical rebate on the adjustment ring side face of gap relative with the adjustment screwed hole of housing, the back lash of the rack and pinion 3 of this state is maximum, adjustment screw 4 is put into the screwed hole of housing, adjustment screw is made to enter in cone tank, when adjusting the threaded end crown at the bottom of cone tank time, continue to rotate, gap adjustment ring turns an angle (being generally no greater than 5 °), when back lash meets the requirements, stop operating, in order to prevent vibration during vehicle to run, cause adjusting screw loosening, the variation of back lash, riveting point or perfusion glue can be adopted to make adjustment screw fix.
Claims (2)
1. an automobile steering gear rack and gear backlash guiding mechanism, including rack and pinion, it is characterized in that: it is eccentric orfice that the gap slippery with tooth bar adjusts annular distance, in the sliding hole being assigned in steering gear housing of described gap adjustment ring, the side face of described gap adjustment ring is provided with and the cone tank of gap adjustment ring axis perpendicular, the notch of this cone tank is big and bottom land is little, described steering gear housing is provided with the screwed hole relative with the bottom land of described cone tank, adjust screw and this corresponding threaded holes, the side face of adjustment ring one end, described gap is provided with projection, before this projection, adjust ring body with left side and gap afterwards to be not attached to, the partial outer face of this projection is higher than the outer peripheral face of gap adjustment ring, should sliding higher than the projection of gap adjustment ring side face and the cannelure on steering gear housing hole wall join.
2. a kind of automobile steering gear rack according to claim 1 and gear backlash guiding mechanism, it is characterised in that: the side face of gap adjustment ring is provided with the cannelure matched with O RunddichtringO, and this cannelure is relative with the cannelure on steering gear housing hole wall.
