Background technique
In automobile steering system, steering column is directly connected by universal joint with commutator, and steering column is assemblied in cockpit, and commutator is installed in engine compartment, therefore needs perforate on automobile body front wall metal plate.In order to prevent rainwater, dust, outside air, noise etc. from entering operator cabin, need to arrange steering shaft seal closure to isolate between front wall panel beating through hole and steering column.Steering shaft seal closure main body is generally the cover body of both ends open, and two ends are tightly connected with automobile body front wall metal plate and steering column respectively.
Most prior art, if the seal closure of Chinese patent Authorization Notice No. involved by the utility model patent of CN 201249716Y is in order to reach enough join strengths and sealing when mounted, joint, two ends needs to introduce the complementary parts such as cassette tape, connecting plate or packing ring, assembly process is comparatively loaded down with trivial details, affects efficiency of assembling.
Summary of the invention
For solving above-mentioned problems of the prior art, the utility model provides a kind of steering axles seal closure of integrative-structure, just can reach enough join strengths and good sealing effect in assembly process without the need to introducing auxiliary component.
Steering axles seal closure described in the utility model comprises sealing cover body and is connected base, described sealing cover body is the hollow rubber cover body of both ends open, cover body is divided into three sections, the cylindrical tubes of two sections, front and back in different bore, centre is a changeover portion, and small-bore section of sealing cover body and steering column are tightly connected.
Described sealing cover body extends plane of putting more energy into and connects base outside heavy caliber end, connects on base and is provided with some screws around sealing cover body heavy caliber end, and be bolted with automobile body front wall metal plate.Connect base to fit tightly with automobile body front wall metal plate, ensure the Tightening moment of fixing bolt simultaneously.
Described connection base arranges the shirt rim of some roads to lower convexity with automobile body front wall metal plate surface of contact around front wall panel beating through hole, shirt rim is by the effect of bolt presses power, with automobile body front wall metal plate interference fit, prevent dust, water and air through surface of contact into the car.
Described connection base belongs to vulcanization steel plate material, has multi-layer structure, connects in base and is inlaid with a stiffened steel plates layer, and wrap up with rubber layer at the upper and lower surface of stiffened steel plates layer.Stiffened steel plates sulfuration is entered with the connection base interlayer of sealing cover body one in course of working.
The small-bore intersegmental part of described sealing cover body is inlaid with wear-resistant seal circle, can coordinate play dustproof effect with steering column.
Preferably, cross section, described shirt rim is semicircle, section radius R=1.5mm.
Preferably, described steering shaft sealing cover body is natural rubber (NR) material.
Preferably, described seal ring is high density polyethylene (HDPE) (HDPE) material, and have good wear resistance, friction factor is little.
Preferably, on described connection base, screw quantity is no less than 2.
Preferably, the quantity of described shirt rim is no less than 3 roads.
The beneficial effects of the utility model are: steering shaft seal closure is structure as a whole, be easy to manufacturing, be directly connected with steering column and automobile body front wall metal plate during assembling, while guarantee sealing effect, reduce amount of parts, simplify assemble flow, improve efficiency of assembling.
