Abstract
The utility model discloses a spring device of an automobile electric power steering system. The spring device comprises a spring, wherein the spring is mounted on a steering shaft and contacted with an upper steering pipe when a steering wheel is veered, a roller is arranged on a contacted position of the spring and the upper steering pipe, and thus rolling friction is formed. According to the technical scheme of the spring device, a sliding block is changed to the roller, original sliding friction is changed to the rolling friction, thus friction resistance is reduced, transitional abrasion and friction noise are avoided, and user experience and system reliability when the steering wheel is adjusted are greatly improved.
Description
Technical field
The utility model relates to a kind of motorcar electric steering boost system, and specifically, what relate to is the spring installation of automobile electric booster steering system.
Background technology
In running car, divertical motion is the most basic motion.We handle and control the travel direction of automobile by bearing circle, thereby realize the intention of travelling of oneself.Automobile electric booster steering system refers to realize wheel steering by means of automotive engine by motor force under the control of chaufeur.
In the existing automobile electric booster steering system, as shown in Figure 1, use spring block (parts 1,2), the design shortcoming: slide block when bearing circle is adjusted and the friction force between last steering tube bigger, be prone to wearing and tearing and noise, the impression of the chaufeur when influence is regulated.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of spring installation of automobile electric booster steering system is provided, and reduces wear and noise, improves the driving experience when regulating.
For realizing above-mentioned purpose, the spring installation of automobile electric booster steering system described in the utility model comprises spring, and described spring is installed on the steering shaft and contacts with last steering tube when wheel steering, described spring and the described steering tube contact position of going up are provided with roller, form friction of rolling.
Preferably, described spring is formed by connecting by connecting portion by two identical conveyor screws, and wherein two spirochetal ends extend to and turn round arm, and the other end extends to connecting portion, forms an integral body by connecting portion.
Preferably, described connecting portion is " U " shape.
Preferably, described roller is arranged on described connecting portion " U " shape bottom.
Preferably, be a through hole in the middle of the described roller, this through hole passes " U " shape bottom of described connecting portion.
The utility model beneficial effect: the slide block that will have now in the design plan changes to roller, this scheme has changed original cliding friction into friction of rolling, reduced friction drag, avoided inordinate wear and friction noise, the user's impression when having improved the bearing circle adjusting greatly and the reliability of system.
Description of drawings
Fig. 1 is existing spring block structural representation.
Fig. 2 is the utility model structural representation.
The specific embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.
As shown in Figure 2, present embodiment provides a kind of spring installation of automobile electric booster steering system, comprises spring 1, and described spring 1 is installed on the steering shaft and contacts with last steering tube when wheel steering, described spring 1 is provided with roller 3 with the described steering tube contact position of going up, and forms friction of rolling.
In the present embodiment, described spring 1 is formed by connecting by connecting portion 6 by two identical conveyor screws 4,5, and wherein two conveyor screws 4, an end of 5 extend to and turn round arm, and the other end extends to connecting portion 6, forms an integral body by connecting portion 6.
In the present embodiment, described connecting portion 6 is " U " shape.
In the present embodiment, described roller 3 is arranged on " U " shape bottom of described connecting portion 6.
In the present embodiment, be a through hole in the middle of the described roller 3, pass " U " shape bottom of described connecting portion 6 by this through hole, finish assembling.
Present embodiment changes to roller (see Fig. 2 3) with the slide block in original design plan (seeing 2 among Fig. 1), this scheme has changed original cliding friction into friction of rolling, reduced friction drag, inordinate wear and friction noise have been avoided, the user's impression when having improved the bearing circle adjusting greatly and the reliability of system.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
