Problems solved by technology

During the steering process of the car, since the force generated by the bearing of the gear shaft is mainly concentrated on the second housing 2 of the steering gear housing, it is easy to cause the rack housing 2a, the gear housing 2b and the adjustment screw mounting hole 2c to be damaged. If the root stress is too large, long-term use will cause the root to break, which will affect the normal operation of the steering gear

Embodiment Construction

[0010] Below by embodiment, in conjunction with accompanying drawing, the present invention is described in further detail:

[0011] Such as figure 2 The steering gear housing shown is composed of a first housing 1, a second housing 2, a connecting shaft 3 and the like. The connecting shaft 3 is arranged between the first housing 1 and the second housing 2 , and the first housing 1 and the second housing 2 are press-fitted on both ends of the connecting shaft 3 .

[0012] The second housing 2 is provided with a rack housing 2a, a gear housing 2b and an adjusting screw mounting hole 2c whose axes are perpendicular to each other, and is respectively used for installing a rack, a gear and an adjusting screw. The rack housing 2a is arranged coaxially with the connecting shaft 3, the gear housing 2b is located directly above the rack housing 2a, and the adjusting screw mounting hole 2c is located directly in front of the rack housing 2a.

[0013] The root of the gear housing 2b ...

Abstract

The invention discloses a steering gear shell. The steering gear shell consists of a first shell (1), a second shell (2) and a connection shaft (3), wherein the second shell (2) is provided with a rack shell (2a), a gear shell (2b) and an adjusting screw mounting hole (2c) whose axles are perpendicular to each other; the root of the gear shell (2b) is provided with reinforcing ribs (4) in diffused distribution; and a reinforcing rib (4) is arranged between the adjusting screw mounting hole (2c) and the rack shell (2a). The problems of rotation, deformation and fracture of the steering gear shell are effectively solved.

Description

technical field [0001] The invention relates to automobile steering gear parts, in particular to a rack and pinion type automobile steering gear housing. Background technique [0002] The rack and pinion steering gear usually includes a steering gear housing, a gear, a rack, an adjustment screw and a rack guide block. The steering gear is at the lower end of the steering main shaft and meshes with the steering rack. When the steering wheel is turned, the gear in the steering gear turns, which drives the rack in the steering gear to move in the direction of the steering wheel. The action of the steering gear rack is transmitted to the steering knuckle arm through the end of the steering gear rack and the end of the steering rod, so that the wheels turn. In the steering gear, the steering gear housing is used to support and fix gears and racks. [0003] Such as figure 1 The steering gear housing shown is press-fitted by the first housing 1, the second housing 2 and the conn...
