Abstract
The utility model discloses an automobile electric power-assisted steering system provided with a sliding bushing. The automobile electric power-assisted steering system provided with the sliding bushing comprises an upper steering shaft, an inner steering pipe and the sliding bushing. The sliding bushing is matched with the upper steering shaft. A gap is formed between the upper steering shaft and the inner steering pipe through the sliding bushing. When a whole automobile is crashed, the sliding bushing can not only reduce abrasion between the upper steering shaft and the inner steering pipe, but also be capable of well controlling the gap between the upper steering shaft and the inner steering pipe, crumple is successfully achieved, and safety of a driver is protected. The automobile electric power-assisted steering system provided with the sliding bushing is simple in structure, convenient to use and practical.
Description
Technical field
The utility model relates to a kind of automobile electric booster steering system, and specifically, what relate to is a kind of automobile electric booster steering system that is provided with slide bushing.
Background technology
Lining is for outside the mechanical part, to reach the auxiliary equipment of effects such as sealing, abrasion protection.The use alerting ability of lining is than higher, and the effect that it can play is also a lot, and lining is the base part that equipment is protected in short.The use of lining can reduce wearing and tearing, vibration and the noise of equipment, and the anti-corrosion effect is arranged; The use of lining can also make things convenient for the maintenance of mechanical equipment, structure and the manufacturing process of simplified apparatus.The effect that lining plays in real work and its applied environment and purpose have much relations: in the valve applications field, lining is entangled valve rod by device in valve gap, with this leakage that reduces valve, reaches sealing function; In the bearing application, the use of lining can reduce the wearing and tearing between bearing and the axle bed, avoids the effects such as gap increase between axle and the hole.
In that automobile is unexpected when the car load collision takes place because the stressed bending of last steering shaft, and with interior steering tube direct friction, influence system's crumple performance, weaken the protection to the driver, wear and tear easily between the steering swivel system part simultaneously.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of automobile electric booster steering system that is provided with slide bushing is provided, and makes whole tubing string keep original attitude, and finishes crumple smoothly, protection driver's safety.
For realizing above-mentioned purpose, a kind of automobile electric booster steering system that is provided with slide bushing described in the utility model, comprise steering shaft, interior steering tube and slide bushing, described slide bushing cooperates with the described steering shaft of going up, and described going up between steering shaft and the described interior steering tube forms a gap by described slide bushing.
Described slide bushing is the hollow cylinder body structure.
Described slide bushing is that soft material is made.
When vehicle meets accident the car load collision, the stressed crooked crumple that takes place of described upward steering shaft, thereby and in described the steering tube inwall move with described in steering tube rub, this moment, described slide bushing can be good at controlling described gap of going up between steering shaft and the described interior steering tube, make the described steering shaft of going up keep original attitude and finish crumple smoothly, thus protection driver's safety; And the wearing and tearing of the parts of having avoided described upward steering shaft and described interior steering tube directly to rub and having caused.
Slide bushing described in the utility model not only can reduce the wearing and tearing of going up between steering shaft and the interior steering tube, and the gap between steering shaft and the interior steering tube on can better controlled, and finishes crumple smoothly, protects driver's safety.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model slide bushing
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 1, present embodiment provides a kind of automobile electric booster steering system that is provided with slide bushing, comprises steering shaft 2, interior steering tube 3 and slide bushing 1, and described slide bushing 1 cooperates with the described steering shaft 2 of going up, and with described interior steering tube 3 gap is arranged.
As shown in Figure 2, the described slide bushing 1 of present embodiment is the hollow cylinder body structure.
The described slide bushing 1 of present embodiment is soft material, such as materials such as soft metal, rubber, nylon and non-metal poly-mers.
As shown in Figure 1, sense of motion when left arrow is represented to collide is subjected to force direction when right arrow is represented to collide.When vehicle meets accident the car load collision, the described upward steering shaft 2 stressed crooked crumples that take place, thereby and in described steering tube 3 inwalls move with described in steering tube 3 rub, this moment, described slide bushing 1 can be good at controlling described gap of going up between steering shaft 2 and the described interior steering tube 3, make the described steering shaft 2 of going up keep original attitude and finish crumple smoothly, thus protection driver's safety; And described slide bushing 1 has also been avoided described wearing and tearing of going up steering shaft 2 and the described interior steering tube 3 direct parts that friction take place and cause, and has made things convenient for maintenance and the replacing in later stage.
To sum up, the utility model not only can reduce the wearing and tearing of going up between steering shaft and the interior steering tube, and the gap between steering shaft and the interior steering tube on can better controlled, makes whole tubing string keep original attitude, and finishes crumple smoothly, protects driver's safety.
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.
