Description
Technical field
The present invention relates to automobile steering devices, and in particular to a kind of supporting and limiting device of rack-and-pinion manual steering gear.
Background technology
In order to improve the service life of rack-and-pinion manual steering gear and steering, rack and pinion steering gear is in the machine of progress
When tool steering assembly designs, it will usually design a kind of supporting and limiting device to realize reduction frictional force, support the purpose of rack.
Common supporting and limiting device is embedding in the housing there is usually one bushing, to realize the purpose of support rack.It is such simple
Supporting and limiting device, technique is unstable during assembling, and is easy to cause quality problems.
The content of the invention
Easy to assembly it is an object of the invention to overcome the deficiencies of the prior art and provide a kind of process stabilizing, support is reliable
Rack-and-pinion manual steering gear supporting and limiting device.
To achieve these goals, the technical solution adopted by the present invention is：
The supporting and limiting device of this kind of rack-and-pinion manual steering gear, the steering gear include housing and rack, the branch
Supportting position-limit mechanism includes the bushing and bushing baffle ring that are arranged between the rack and the housing, bushing baffle ring one end suit
On the bushing, the other end of the bushing baffle ring is sleeved on buffering baffle ring, and the buffering shield ring sleeve is mounted in the rack
On；The bushing inner wall is arranged on oil storage tank, the bushing inner wall and rack outer wall interference fit；Bushing one end installation
On the bushing baffle ring, the bushing other end inner wall is equipped with guide surface, and the end outer wall that the bushing sets guide surface is equipped with
Chamfering.
The advantage of the invention is that：Bushing baffle ring stationary bushing and buffering baffle ring, branch is formed after three's assembling in the present invention
Support structure can reach support rack, reduce frictional force, prevent steering gear from turning to clamping stagnation, pull rod /V and the effect for reducing noise；
Its processing technology and assembly method simple possible, process stabilizing, solve that existing supporting and limiting device assembly technology is unstable, machine
Tool steering assembly abnormal sound turns to the problem of clamping stagnation.The setting of guide surface on bushing, facilitates the installation of bushing；Falling on bushing
Angle facilitates the assembling between bushing and housing.

Specific embodiment
Below against attached drawing, by the description to optimum embodiment, the specific embodiment of the present invention is made further detailed
Thin explanation.
As shown in Figure 1, the supporting and limiting device of this kind of rack-and-pinion manual steering gear, steering gear includes housing 4 and rack
5, support limit mechanism includes the bushing 1 and bushing baffle ring 2 that are arranged between rack 5 and housing 4, and 2 one end of bushing baffle ring is sleeved on
On bushing 1, the other end of bushing baffle ring 2 is sleeved on buffering baffle ring 3, and buffering baffle ring 3 is sleeved on rack 5.As shown in Fig. 2,
1 inner wall of bushing is equipped with oil storage tank 7,1 inner wall of bushing and 5 outer wall of rack interference fit.The endoporus of bushing 1 adds oil storage tank 7, lining
It covers 1 inner wall to be interference fitted with 5 outer circle of rack, plays the role of supporting rack 5, reduce support force of rubbing, prevent from turning to clamping stagnation.
1 one end of bushing is mounted on bushing baffle ring 2, and 1 other end inner wall of bushing is equipped with guide surface 11, and bushing 1 sets guide surface
The 11 end outer wall is equipped with chamfering 12.1 inner wall of bushing and rack 5 are interference fitted, and the setting of guide surface 11 on bushing 1 facilitates lining
The installation of set 1.Chamfering 12 on bushing 1 facilitates the assembling between bushing 1 and housing 4.
2 stationary bushing 1 of bushing baffle ring and buffering baffle ring 3 can reach support rack 5, reduce frictional force, is anti-after three's assembling
Only steering gear turns to clamping stagnation, pull rod /V and the effect for reducing noise, processing technology and assembly method simple possible, solves
The problem of existing supporting and limiting device assembly technology is unstable, manual steering gear assembly abnormal sound, steering clamping stagnation.Buffer 3 material of baffle ring
Expect for nonmetallic materials, to be capable of providing preferable cushioning effect.
For bushing 1 in housing 4 and bushing baffle ring 2,2 stationary bushing 1 of bushing baffle ring and buffering baffle ring 3, buffering baffle ring 3 are embedding
In bushing baffle ring 2,3 right side of buffering baffle ring is confined planes, and the material of buffering baffle ring 3 is nonmetallic materials.
Oil storage tank 7 is annular groove, and oil storage tank 7 is evenly distributed on 1 inner wall of bushing, the setting of oil storage tank 7, is provided reliable equal
Even lubricating action, the effect for further improve and reduce support force of rubbing, preventing from turning to clamping stagnation.
3 empty set of baffle ring is buffered on rack 5；Improve reliable and stable cushioning effect.
2 outer wall of bushing baffle ring and 4 inner wall of housing are pressed into contact with；Bushing baffle ring 2 provides reliable and stable support fixation.
The present invention adds oil storage tank 7,2 stationary bushing 1 of bushing baffle ring and buffering baffle ring 3 in 1 endoporus of bushing, buffers baffle ring
3 materials are nonmetallic materials, and support rack 5 is can reach after assembling, frictional force is reduced, prevents from turning to clamping stagnation, 6 /V of pull rod, drop
It is unstable to solve existing supporting and limiting device assembly technology for the effect of low noise, processing technology and assembly method simple possible
Fixed, manual steering gear assembly abnormal sound turns to the problem of clamping stagnation.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as employing the methodology and skill of the present invention
The improvement for the various unsubstantialities that art scheme carries out, within protection scope of the present invention.
