Description
Technical field
The present invention relates to automobile steering devices, and in particular to the support 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
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of process stabilizings, good buffer effect, and support can
The support device of the rack-and-pinion manual steering gear leaned on.
To achieve these goals, the technical solution adopted by the present invention is：
The support device of the rack-and-pinion manual steering gear, the steering gear include housing and rack, the support limit
Mechanism includes the bushing and bushing baffle ring that are arranged between the rack and the housing, and described bushing baffle ring one end is sleeved on described
On bushing, the other end of the bushing baffle ring is sleeved on buffering baffle ring, and the buffering shield ring sleeve is on the rack；It is described
Bushing inner wall is arranged on oil storage tank, the bushing inner wall and rack outer wall interference fit；The rack is connected with pull rod, described
It buffers baffle ring one end to be mounted on the bushing baffle ring, the other end of the buffering baffle ring stretches out the bushing baffle ring, described slow
It rushes baffle ring and stretches out the end end face of the bushing baffle ring for pull rod limiting buffer face.
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.After pull rod runs to extreme position, the pull rod limiting buffer with buffering baffle ring
Face is hit, and buffering baffle ring is made of nonmetallic materials, and pull rod is metal material, and sound is minimum after shock, can effectively reduce and make an uproar
Sound.

31st, pull rod limiting buffer face.
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 support device of this kind of rack-and-pinion manual steering gear, steering gear includes housing 4 and rack 5, branch
Supportting position-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 bushing 1
On, 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, bushing 1
Inner wall 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, in bushing 1
Wall is interference fitted with 5 outer circle of rack, is played the role of supporting rack 5, is reduced support force of rubbing, prevents from turning to clamping stagnation.
Rack 5 is connected with pull rod 6, and 3 one end of buffering baffle ring is mounted on bushing baffle ring 2, and the other end of buffering baffle ring 3 stretches out
Bushing baffle ring 2, the end end face that buffering baffle ring 3 stretches out bushing baffle ring 2 are pull rod limiting buffer face 31.Pull rod 6 runs to the limit
Behind position, the pull rod limiting buffer face 31 with buffering baffle ring 3 is hit, and buffering baffle ring 3 is made of nonmetallic materials, and pull rod 6 is gold
Belong to material, sound is minimum after shock, can effectively reduce noise.
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.
