Problems solved by technology

[0002] In the current common rack steering gear, the limit block at the end of the rack collides with the steering gear housing. At this time, the steering wheel of the driver hits the limit position and cannot continue to rotate. When turning the steering wheel, you will feel a kind of impact when you hit the limit position, which is formed by the impact between the rack limit block and the steering gear housing, which reduces the service life of the steering gear

Abstract

The invention discloses a limiting device of a rack steering gear. The limiting device comprises a limiting mechanism (1) which is internally provided with an elastic mechanism (2), the elastic mechanism (2) comprises a base (6), at least two ball holes and at least two spring holes are reserved on the base (6), a ball (3) is arranged in each ball hole, the balls (3) are connected at the bottoms of the ball holes through short springs (4) and contact with an inner surface (11) of the limiting mechanism (1), a long spring (5) is arranged in each spring hole, one ends of the long springs (5) are connected with the inner surface (11) of the limiting mechanism (1), and the other ends of the long springs (5) are connected with the bottoms of the spring holes. The limiting device of the rack steering gear can function in buffering, so that working pressure of the steering gear is greatly reduced, and the service life of the steering gear is prolonged.

Description

technical field [0001] The invention relates to a rack steering gear, in particular to a limiting device of the rack steering gear. Background technique [0002] In the current common rack steering gear, the limit block at the end of the rack collides with the steering gear housing. At this time, the steering wheel of the driver hits the limit position and cannot continue to rotate. When turning the steering wheel, you will feel a kind of impact when you hit the limit position, which is formed by the impact between the rack limit block and the steering gear housing, which reduces the service life of the steering gear. Contents of the invention [0003] In order to solve the problem that the impact between the rack limit block and the steering gear housing will affect the service life of the steering gear, the present invention provides a limit device for the rack steering gear, including a limit mechanism 1, the The limiting mechanism 1 is provided with an elastic mechani...
