Abstract
The utility model relates to a rack bearing seat assembly convenient to rework, and belongs to the technical field of vehicle rack and pinion steering gears. The rack bearing seat assembly comprises a rack bearing seat body and O-shaped rubber seal rings which are arranged on the rack bearing seat body through grooves. A chamfering groove is formed in a periphery of an inner hole of the rack bearing seat body. Due to the fact that the chamfering groove is formed in the inner hole of the rack bearing seat body, on the condition that using performance of the rack bearing seat assembly is not influenced, the rack bearing seat assembly can be taken out from a horizontal hole of a shell of a steering gear easily, and the problems that an existing rack bearing seat assembly cannot be taken out from a horizontal hole position of the steering gear easily in the process of rework of the rack bearing seat assembly, difficulties are increased to operators, and time is consumed are solved. The rack bearing seat assembly convenient to rework is simple in structure and good in practicality, and does not need to disassemble other parts of a steering gear assembly.
Description
Technical field
The utility model relates to a kind of rack supporting seat assembly of being convenient to do over again, and belongs to automobile gear tooth bar deflector technical field.
Background technology
Automobile in the process of moving, the direction that often needs conversion to travel is namely carried out motor turning.Deflector (or being called steering box) is to do the device of proper transformation between the moment of rotation of bearing circle and swing offset, power is passed to the mechanism that wheel makes motor turning, and rack and pinion steering gear is to realize this conversion by the gear motion between wheel and rack.Automobile steering device is broadly divided into three classes by assist type: manual steering gear; Hydraulic power steering device and electric booster steering device.Any deflector all has related request to the back lash of rack-and-gear, and this gap is to adjust structure by one to control.This adjustment structure is comprised of rack supporting seat assembly (or being called the tooth bar bracket), spring, adjustment plug screw.The inner arc surface of rack supporting seat assembly contacts with tooth bar, come the gap of adjusting gear tooth bar by adjusting gear rack supporting base assembly and the gap of adjusting plug screw, spring is to predetermincd tension of tooth bar, rack-and-gear also can better be meshed under free state, also can play in addition the effect of buffering and damping when the road surface during to an antagonistic force of tooth bar.
Due to the rack supporting seat general assembly in the cross-drilled hole of steering gear housing, performance requriements because of product, the gap of rack supporting seat assembly and housing cross-drilled hole is very little, and the endoporus on rack supporting seat assembly ground is smooth surface, therefore be difficult to separately the rack supporting seat assembly be taken out in cross-drilled hole.And in order to abate the noise, the side of part rack supporting seat assembly can increase one or more O type rubber seal, so greatly increased the friction force of rack supporting seat assembly and housing, to take out the rack supporting seat assembly in the housing cross-drilled hole more difficult thereby make.
In the checking of product, production process, often need to do over again to this adjusting mechanism, this just requires the rack supporting seat assembly is taken out in the housing cross-drilled hole.At present, the method for taking out the rack supporting seat assembly has two kinds: the one, and use nipping pliers to clamp the endoporus on rack supporting seat assembly ground, it is extracted from the housing cross-drilled hole.The 2nd, part rack supporting seat assembly can't take out with nipping pliers, at first valve assembly and the tooth bar assembly of deflector is pulled down, then rack supporting seat is taken out with accessory from housing main aperture position.
Above-mentioned is which kind of method is all a no small difficult problem for the operative employee, and unusual time-consuming, and this and current increasingly compact productive temp are not inconsistent yet.
Summary of the invention
The purpose of this utility model just is: providing a kind of can take out the rack supporting seat assembly comparatively easily from the housing cross-drilled hole, and need not to disassemble or the rack supporting seat assembly of being convenient to do over again of mobile other parts of steering assembly.
The technical solution of the utility model is:
A kind of rack supporting seat assembly of being convenient to do over again comprises the rack supporting seat body and is arranged on O type rubber seal on the rack supporting seat body by groove, it is characterized in that: be provided with chamfer groove on the endoporus circumference of rack supporting seat body.
The utility model has the advantage of:
The rack supporting seat assembly that this is convenient to do over again, by the chamfer groove that arranges on rack supporting seat body endoporus, do not affecting under the in-use performance prerequisite of rack supporting seat assembly, can comparatively easily the rack supporting seat assembly be taken out in the steering gear housing cross-drilled hole, avoided existing rack supporting seat assembly in the process of doing over again, due to the position that there is no the application of force, make it be very difficult to take out from the position of steering gear housing cross-drilled hole, not only increased difficulty to the operative employee, and very time consuming problem.This rack supporting seat assembly of being convenient to do over again has simple in structure, and the characteristics that practicality is good the process that the rack supporting seat assembly takes out, need not to disassemble other parts of steering assembly in the steering gear housing cross-drilled hole.
Description of drawings
Accompanying drawing 1 is sectional structure schematic diagram of the present utility model.
In figure: 1, rack supporting seat body, 2, groove, 3, O type rubber seal, 4, chamfer groove.
The specific embodiment
This rack supporting seat assembly of being convenient to do over again comprises rack supporting seat body 1 and is arranged on O type rubber seal 3 on rack supporting seat body 1 by groove 2.Be provided with chamfer groove 4 on the endoporus circumference of rack supporting seat body 1.
the rack supporting seat assembly that this is convenient to do over again, by the chamfer groove 4 that arranges on rack supporting seat body 1 endoporus as the point of application, do not affecting under the in-use performance prerequisite of rack supporting seat assembly, by the nipping pliers of use with outer point hook, can comparatively easily the rack supporting seat assembly be taken out in the steering gear housing cross-drilled hole, solved existing rack supporting seat assembly in the process of doing over again, due to the position that there is no the application of force, make it be very difficult to take out from the position of steering gear housing cross-drilled hole, not only increased difficulty to the operative employee, and very time consuming problem.This rack supporting seat assembly of being convenient to do over again has simple in structure, and the characteristics that practicality is good the process that the rack supporting seat assembly takes out, need not to disassemble other parts of steering assembly in the steering gear housing cross-drilled hole.
