Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 , a pressure-adjustable steering gear rack pressing structure, has:

[0026] Intermeshing gear and rack 1 installed in housing 7;

[0027] Press the support block 3 of the rack 1, and the end of the support block 3 opposite to the rack 1 is arc-shaped;

[0028] The arc-shaped pressing piece 2 arranged between the supporting pressure block 3 and the rack 1, such as Figure 6 As shown, the side of the pressing piece 2 in contact with the rack 1 is provided with an oil groove storing a lubricating medium; the lubricating medium is lubricating oil or grease.

[0029] The gland 5 is provided with a sealing screw 6 penetrating through the gland 5, and the sealing screw 6 is made of rubber to prevent dust and water.

Abstract

The invention discloses a pressure-adjustable steering gear rack compaction structure. The pressure-adjustable steering gear rack compaction structure comprises a gear, a rack (1), a supporting pressure block (3), an arc-shaped pressure sheet (2), a pressure cover (5) and a spring (4), wherein the gear and the rack (1) are engaged with each other and mounted in a housing (7); the supporting pressure block (3) compacts the rack (1) and one end, opposite to the rack (1), of the supporting pressure block (3) is arc-shaped; the arc-shaped pressure sheet (2) is arranged between the supporting pressure block (3) and the rack (1), and an oil tank which stores a lubrication medium is arranged on one side, in contact with the rack (1), of the pressure sheet (2); the pressure cover (5) compacts the supporting pressure block (3) and is in threaded connection with the housing (7); and the spring (4) is arranged between the pressure cover (5) and the supporting pressure block (3). The deformation degree of the spring (4) is changed by changing the screw-in degree of the pressure cover (5), so that the compaction force is adjusted, the area of contact with the rack (1) is enlarged, the friction is reduced, the abrasion of the rack (1) is reduced, and the service life of a steering gear is prolonged; and the compaction force of the spring (4) is adjusted through a sealing screw (6).

Description

technical field [0001] The invention belongs to the technical field of automobile steering gears, and in particular relates to a pressure-adjustable steering rack pressing structure. Background technique [0002] In the traditional technology, the rack of the rack-and-pinion steering gear is directly pressed by a pressing block whose end face is flat. [0003] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: the contact area between the plane press block and the rack is small, which easily causes the wear of the rack, reduces the service life of the steering gear, and the pressing force is insufficient. adjust. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a pressure-adjustable steering gear rack that reduces the friction between the pressure block and the rack, reduces the wear of the rack, and has adjustable pressing force and impro...
