The flange lip is fitted closely with front baffle metal plate, and the rubber compression piece is vertically pressed along front baffle metal plate Z-direction
Contracting 10mm.
The sealing lip of the flange lip is adjacent to front baffle metal plate interference fit.
More ribs are connected between the connecting portion and the flange lip.
Further, the plastic feet includes plastic feet body, the plastic feet body upper part be equipped with it is described
The upper end of rubber compression piece connection, the plastic feet body lower part are equipped with skirt end, the plastic feet body with it is described
Bottom is equipped between skirt end, the lower face of the bottom is bonded the axial limit of progress with steering gear pinion gear housing upper surface
Position.
The bottom center of the plastic feet is equipped with the axle sleeve with steering gear pinion gear input shaft clearance fit, the axis
Set upper side passes through the rubber compression piece bottom.
The aperture of the skirt end of the plastic feet is spacing with row circumference is merged into steering gear pinion housing body space.
The end face contacted on the upper end of the plastic feet with the rubber compression piece is equipped with sealed muscle.
Beneficial effects of the present invention are：
1st, rubber compression piece is fitted closely by compression and metal plate, plastic feet and steering gear pinion gear housing interference
Coordinate, so as to block the path of sound transmission, cockpit NVH perceived qualities are good, work well with water proof and dust proof.
2nd, this construction seals fills assembly suppliers carry out portion's dress (being integrated with steering gear and subframe) in portion, saves total
The step of being assembled between entrucking, improves assembly shop productive temp.
3rd, this construction seals at the same time can seal steering gear pinion end, and steering gear pinion end need not reassemble
Dust cover, has saved a sub- part of steering gear.
4th, jackshaft is fully enclosed in cockpit by this sealing structure, makes middle shaft universal-joint from the erosion of muddy water,
Extend jackshaft life cycle.
