Power redirector of awl-end screw axial limiting

Abstract

The invention relates to a conical radial stop screw power steering machine. Per conical end stop screw, it effectively prevents the nylon retainer broken, bearing base string movement resulted O type ring wearing and oil leakage due to axial string movement of the rotating rocker arm, expanded radial space of the rocker arm shaft gear fan, expanding gear width, increasing bearing ability of the gear, increased bearing width C to use cheaper rolling bearing, reducing cost, with eccentric adjusting steering gear teething gap less than 2mm, not only reducing the machining precision of the steering gear shell, reducing gear fan common normal tolerance, rack spline length bar tolerance, being able to increase gear fan and rack smoothness, improving teething feature of the steering gear, ensuring the free from gap, reducing rotation moment undulating value, effectively preventing the rack stress accumulation but broken.

Description

technical field [0001] The invention relates to an integrated power steering gear for automobiles, in particular to a power steering gear with tapered end screws axially limited. Background technique [0002] At present, many steering gear manufacturers at home and abroad have adopted the power shown in Figure 9, using nylon circlips 16, 17 and elastic circlips 8, 13 for holes to limit the axial movement of bearing seats 5, 15 and steering rocker shaft 3. Steering gear, due to the relatively large dimensional tolerance of the thickness of the nylon retaining ring, the elastic retaining ring for the hole, and the groove distance H, the maximum gap between H can reach 2mm, so during the steering process of the car, the reaction force of the road to the steering wheel, The impact force is transmitted to the axial component of the steering rocker shaft 3 through the straight rod, so that the steering rocker moves axially left and right and hits the bearing sleeve through the nyl...
