Abstract

The utility model discloses an improved steering device, which includes a steering shell (3) and a steering worm (5) installed inside the steering shell (3), wherein the steering worm (5) is installed on a steering shaft (8), an upper bearing (6) and a lower bearing (3) are arranged at two ends of the steering worm (5), and a blind hole is provided at the lower end of the steering shell (3). The upper bearing (6) and the lower bearing (4) are both standard bearings. The improved steering device provided in the utility model effectively prevents the prior oil seepage problem, ensures the normal usage of the steering device, and improves the service life of the steering device. The improved steering device has the advantages of good concentricity of the bearing and the steering device, prolonged service life of the bearing, safe usage of the steering device, and convenient replacement of the bearing.

Description

Improved deflector

Technical field

The utility model relates to a kind of motor vehicle deflector, particularly a kind of power actuated vehicle deflector that improves structure.

Background technology

Existing little four-wheel (side connection) deflector turns to the housing operated by rotary motion that case top lid, housing side cover and housing lower cover are arranged, and installs packing seal additional between each lid and housing.Its shortcoming is that after using after a while, to a certain degree damaging appears in packing seal because aging, rotten etc., the sealing property variation, cause lubricating oil from the outside seepage in slit between lower cover and the housing, thereby increase the wearing and tearing of inner components, when serious even cause turning to malfunctioning.

Another shortcoming of existing deflector is: the bearing inner ring design at steering worm two ends is at the steering worm two ends, with the material of steering worm as the bearing inner ring parts.This two bearing is an established line bearing, can't change bearing separately, maintenance, supporting inconvenience.On the other hand, bearing and steering shaft right alignment are poor, cause turn to dumb, and fragile bearing.

The utility model content

The utility model provides a kind of improved deflector, and technical matters to be solved is to avoid turning to housing lower end oil impregnate by improving structure.Second technical matters to be solved in the utility model is to improve bearing and steering shaft right alignment, and make bearing be easy to supporting, replacing.

The technical scheme that its technical matters that solves the utility model adopts is as follows:

A kind of improved deflector, comprise turning to housing and being installed in the steering worm that turns in the housing that steering worm is installed on the steering shaft, the steering worm two ends also are provided with head bearing and lower bearing, it is characterized in that: turning to the housing lower end is blind hole, i.e. the osed top integrative-structure.

Head bearing and lower bearing are the gauge member bearing, and they are installed in respectively on the steering shaft, and wherein head bearing is positioned at the steering worm upper end, and lower bearing is positioned at the steering worm lower end.

The utlity model has following good effect: (1), will turn to the housing lower end to be improved to blind hole by original through hole, effectively avoided original oil impregnate problem, guaranteed the normal use of deflector, improved the service life of deflector.(2), at the bearing of steering worm two ends installation code spare, guaranteed bearing and steering shaft right alignment on the one hand, prolonged the bearing period of service, guaranteed the safe application performance of deflector; On the other hand, change bearing facility more.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model comprises and has turning to housing 3 and being installed in the steering worm 5 that turns in the housing 3 of case top lid 2, housing side cover that steering worm 5 is installed on the steering shaft 8.Supporting sleeve 1 is fixed on the case top lid 2 by bolt 7.

Wherein, turning to housing 3 lower ends is blind hole, i.e. the osed top integrative-structure.

Head bearing 6 and lower bearing 4 are the gauge member bearing, and they are installed in respectively on the steering shaft 8, and wherein head bearing 6 is positioned at steering worm 5 upper ends, and lower bearing 4 is positioned at steering worm 5 lower ends.

Claims (2)

1, a kind of improved deflector, comprise and turn to housing (3) and be installed in the steering worm (5) that turns in the housing (3), steering worm (5) is installed on the steering shaft (8), steering worm (5) two ends also are provided with head bearing (6) and lower bearing (4), it is characterized in that: turning to housing (3) lower end is blind hole, i.e. the osed top integrative-structure.

2, improved deflector according to claim 1, it is characterized in that: head bearing (6) and lower bearing (4) are the gauge member bearing, they are installed in respectively on the steering shaft (8), and wherein head bearing (6) is positioned at steering worm (5) upper end, and lower bearing (4) is positioned at steering worm (5) lower end.
