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.Bushing baffle ring 2 is solid Determine bushing 1 and buffering baffle ring 3, support rack 5 is can reach after three's assembling, frictional force is reduced, prevents steering gear from turning to clamping stagnation, drawing Bar /V and the effect for reducing noise, processing technology and assembly method simple possible solve existing supporting and limiting device dress With technique is unstable, manual steering gear assembly abnormal sound, turns to the problem of clamping stagnation.It is nonmetallic materials to buffer 3 material of baffle ring, can Preferable cushioning effect is provided.
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.Bushing 1 it is interior Hole adds oil storage tank 7, and 1 inner wall of bushing is interference fitted with 5 outer circle of rack, plays support rack 5, reduces rub support force, anti-rotation stop Effect to clamping stagnation.
If Fig. 3 shows, 2 inner wall of bushing baffle ring is equipped with sleeve of the empty set on rack 5, and 2 inner wall of bushing baffle ring is located at sleeve one Side is equipped with the first installation step 21 of installation bushing 1, and 2 inner wall of bushing baffle ring, which is located at sleeve opposite side and is equipped with and buffers baffle ring 3, matches somebody with somebody The second installation step 22 closed.First installation step 21 facilitates the installation of bushing 1 to assemble, and the second installation step 22 facilitates bumper The assembling of circle 3 further improves bushing 1, bushing baffle ring 2 and the assembling convenience and assembly reliability that buffer baffle ring 3.
One end outer wall that bushing baffle ring 2 sets the first installation step 21 is equipped with the guiding conical surface 25.Bushing baffle ring 2 and housing 4 fill Timing is oriented to the conical surface 25 and plays guiding role, facilitates the assembling of bushing baffle ring 2.
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.
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.
22 front end of the second installation step of bushing baffle ring 2 and buffering baffle ring 3 are pressed into contact with, the second installation of bushing baffle ring 2 The rear end end of step 22 is equipped with rear end portion and is oriented to the conical surface 26.Rear end portion is oriented to the conical surface 26 when buffering the assembling of baffle ring 3, plays and leads To effect, facilitate the assembling of buffering baffle ring 3.
