To achieve these goals, the technical solution adopted in the utility model is:
This kind of car deflector input shaft protective jacket, by protective jacket stem, protective jacket corrugated part and protective jacket tail
Portion is constituted, and described protective jacket stem is provided with the elastic cuffs structure lip being sleeved on described power shaft；Described
Protective jacket stem is positioned at inside described lip and is provided with the draw-in groove installing intermediate jacket；Described intermediate jacket inwall sets
Have along the axially arranged oil storage tank of power shaft；Described protective jacket afterbody and steering gear housing pass through clamp connection.
Described lip and described power shaft interference fit.
Described intermediate jacket and described power shaft matched in clearance.
Described protective jacket afterbody outer wall is provided with annular groove；The inwall of the protective jacket afterbody being provided with annular groove is equal
It is furnished with annular circular arc protruding.
Described oil storage tank is evenly distributed on intermediate jacket inwall.
Described protective jacket tail diameter is more than described protective jacket stem.
The utility model has the advantage of: this kind of car deflector input shaft protective jacket, the lip of protective jacket stem
Mouth can effectively prevent the entrance of muddy water, dust；Intermediate jacket substantially reduces between power shaft and protective jacket
Frictional force, it is ensured that with in the case of card band tightener at protective jacket afterbody, protective jacket stem is not with power shaft
Rotate and twist, add the service life of protective jacket, also ensure that the sealing of steering gear input shaft end
Property, it is ensured that Vehicular turn performance.The present invention improves the sealed horizontal of steering gear input shaft protective jacket, with
Time the highest for production technology level requirement, simple in construction, low cost, reduce rotating torque fluctuation, increase
Add the service life of protective jacket.

Detailed description of the invention
Below against accompanying drawing, by the description to optimum embodiment, to detailed description of the invention of the present utility model
It is described in further detail.
As shown in Figure 1-Figure 3, this kind of car deflector input shaft protective jacket, by protective jacket stem 1, protective jacket
Corrugated part 3 and protective jacket afterbody 4 are constituted；Protective jacket afterbody 4 diameter is more than protective jacket stem 1；Protective jacket is first
Portion 1 is provided with the lip 5 of the elastic cuffs structure being sleeved on power shaft；Protective jacket stem 1 is positioned at lip 5
Side is provided with the draw-in groove 6 installing intermediate jacket 2；Intermediate jacket 2 inwall is provided with along the axially arranged oil storage of power shaft
Groove；Protective jacket afterbody 4 and steering gear housing pass through clamp connection.
Protective jacket stem 1 is provided with the resilient lip 5 in closing in shape of tool coordinated with steering gear input shaft, lip
Mouth 5 is the closing-in structure of taper, and lip 5 is sleeved in power shaft mounting groove, with power shaft mounting groove interference
Coordinate, it is possible to effectively prevent the entrance of muddy water, dust.
Intermediate jacket 2 is stuck in the draw-in groove 6 of protective jacket stem 1, and intermediate jacket 2 can play skeleton simultaneously
Effect, make protective jacket stem 1 be unlikely to deform, intermediate jacket 2 and power shaft matched in clearance, axial oil storage
Groove stores sealing lubricating oil fat.Contact with power shaft due at only lip 5, and scribble oils and fats, power shaft
During rotation little with protective jacket frictional force, reduce steering moment fluctuation, extend the service life of protective jacket.
Protective jacket afterbody 4 is enclosed within steering gear housing upper end, uses card band tightener simultaneously, plays and seals work for a long time
With, prevent muddy water, dust from entering steering from sheath afterbody, also ensure that protective jacket afterbody 4 is in input
Axle rotate time not with steering gear housing friction and produce breakage.
Lip 5 and power shaft interference fit；Lip 5 is less than the diameter of axle size of steering gear input shaft, the two mistake
It is full of cooperation, it is possible to effectively prevent the entrance of muddy water, dust.
Intermediate jacket 2 and power shaft matched in clearance, the internal diameter of intermediate jacket 2 is more than the axle of steering gear input shaft
Footpath, the material of intermediate jacket 2 is PA66+GF30.Intermediate jacket 2 is stuck in draw-in groove 6, intermediate jacket 2
Also functioning to the effect of skeleton, intermediate jacket 2 and power shaft take matched in clearance, add oils and fats in oil storage tank
Lubrication, substantially reduces the frictional force between power shaft and protective jacket；Ensure that and use at protective jacket afterbody 4
In the case of card band tightener, protective jacket stem 1 does not rotates with power shaft and twists, and adds protective jacket
Service life, also ensure that the sealing of steering gear input shaft end.
Protective jacket afterbody 4 outer wall is provided with annular groove 7；It is provided with the inwall of the protective jacket afterbody 4 of annular groove 7
Being evenly equipped with annular circular arc projection 8, inwall forms connected peak valley shape structure.Annular groove 7 is easy to the peace of clip
Dress.Protective jacket afterbody 4 has annular groove 7 structure near port, and there is connected peak valley corresponding section, inner side
Shape structure, is fastened on protective jacket with clip herein and turns to casing body upper end, the annular groove 7 on protective jacket
And the annular circular arc projection 8 of inwall so that protective jacket afterbody 4 and turn to the connection of casing body more to fasten, knot
Structure is relatively reliable.
Oil storage tank is evenly distributed on intermediate jacket 2 inwall；Ensure that protective jacket stem 1 and intermediate jacket 2
Proper lubrication.
This kind of car deflector input shaft protective jacket, what protective jacket stem 1 and power shaft were taked is interference fit,
Can effectively prevent the entrance of muddy water, dust, intermediate jacket 2 is stuck in draw-in groove 6；Intermediate jacket 2 simultaneously
Also functioning to the effect of skeleton, intermediate jacket 2 and power shaft take matched in clearance, add oils and fats in oil storage tank
Lubrication, substantially reduces the frictional force between power shaft and protective jacket；Ensure that and use at protective jacket afterbody 4
In the case of card band tightener, protective jacket stem 1 does not rotates with power shaft and twists, and adds protective jacket
Service life, also ensure that the sealing of steering gear input shaft end.The present invention improves steering gear input shaft
The sealed horizontal of protective jacket, the highest simultaneously for production technology level requirement, simple in construction, low cost, fall
Low rotating torque fluctuation, adds the service life of protective jacket.
Obviously this utility model implements and is not subject to the restrictions described above, as long as have employed this utility model
