Description
Technical field
The utility model relates to a kind of gear rack steering box inter-lobe clearance regulating device.
Background technique
Existing gear rack steering box inter-lobe clearance regulating device, for the rack support seat being set in the rack-and-pinion engagement place, the supporting base back side is provided with helical spring, at the helical spring the other end adjusting plug screw is set, by regulating plug screw regulating tooth rack-and-pinion back lash, supporting base cooperates with the steering box body clearance, can move axially in the steering box housing.There is following problem in this gear rack steering box inter-lobe clearance regulating device: when vehicle driving is on uneven road surface, tire can bring tooth bar bigger impact, this impact passes to supporting base by tooth bar, move after therefore supporting base can tilt and collision of steering box housing or friction partially, collision that brings thus or friction one side partially can be aggravated the related components wearing and tearing and be reduced working life, can produce abnormal sound on the other hand and make the driver drive anxiety, influence driving comfortability.In common tube pillar electric power steering (C-EPS), this problem is even more serious.Because of common tube pillar electric turning booster is to be loaded into moment on the tooth bar, thereby be not only vehicle and cross when jolting the road surface, tire can bring impact to tooth bar, and electric turning booster also can bring impact to tooth bar when producing, and the impact that electric power steering brings also can produce the problems referred to above.
The model utility content
The purpose of this utility model is to provide a kind of gear rack steering box inter-lobe clearance regulating device, the solution tire brings the impact of tooth bar and supporting base, move after causing supporting base to tilt and collision of steering box housing or friction partially, thereby the wearing and tearing of aggravation related components reduce relevant issues such as working life.
To achieve these goals, the technical solution adopted in the utility model is:
Described this gear rack steering box inter-lobe clearance regulating device comprises locking nut, plug screw, supporting base, helical spring, O shape rubber ring.
Described this gear rack steering box inter-lobe clearance regulating device is installed on the steering box housing, is loaded on small gear input shaft and tooth bar in addition on the steering box housing equally.Small gear input shaft and tooth bar engagement driving.
Described supporting base is arranged at a side of tooth bar, and described supporting base one end is connected with tooth bar.
The other end of described supporting base is connected with helical spring one end, and the helical spring the other end is connected with plug screw one end.
Described locking nut is located at the end of plug screw, and locking nut cooperates with the steering box housing.
Described supporting base, helical spring and plug screw all are located at the steering box enclosure interior, described O shape rubber ring is arranged between described supporting base and the steering box shell inner surface, described O shape rubber ring is sleeved on the described supporting base, and with steering box shell inner surface interference fit.
Described O shape rubber ring is formed by elastic material, the O shape rubber ring that is sleeved on the described supporting base plays the energy-absorbing buffering effect to supporting base, it can make and be difficult for when described supporting base is subjected to impacting moving, even described supporting base moves also can not tilt, and can not bump, thereby avoid gouging abrasion and friction noise between supporting base and steering box housing and associated components with the steering box housing.
For guaranteeing the stable of structure, described O shape rubber ring is more than two.
When screwing the locking nut of plug screw end, the spatial position of plug screw, helical spring and supporting base is fixed, and the inter-lobe clearance of described gear rack steering box is fixed.When needs are regulated inter-lobe clearance, unclamp locking nut, regulate plug screw, the plug screw compression helical spring, helical spring pushes tooth bar by supporting base, to realize the inter-lobe clearance adjustment, adjust inter-lobe clearance after, screw locking nut.
Because helical spring is in compressive state, and because the elastic performance of helical spring self, described gear rack steering box inter-lobe clearance regulating device has the gap compensation ability.
Advantage of the present utility model is: by the improvement to the inter-lobe clearance regulating device structure of the described gear rack steering box of prior art, provide a kind of gap compensation ability and can be to the inter-lobe clearance regulating device of supporting base energy-absorbing buffering of having.After the utility model is used, can make the supporting base of inter-lobe clearance regulating device be hit is to be difficult for moving, even move also can not tilt, described supporting base can not bump with steering box housing and associated components, thereby collision noise and friction noise have been avoided, improved driving comfortability, having reduced wearing and tearing and having improved component working life.
