Abstract
The utility model discloses a sensor protection device of an automobile electric power steering system. The sensor protection device of the automobile electric power steering system comprises a sealing ring. The sealing ring is arranged on a sensor. The sensor is inserted into a steering tubular column of the automobile electric power steering system. According to the sensor protection device of the automobile electric power steering system, the V-type sealing ring is added to achieve the effects of an anti-flood wall, the sealing ring can receive oil water which is separated from lubricating grease due to long time use of the lubricating grease, and prevent the oil water from entering the interior of the sensor, and therefore risks caused by a short circuit of the sensor are avoided.
Description
Technical field
The utility model relates to a kind of vehicle electric power-assisted steering device accessory, and specifically, what relate to is a kind of protector for sensor of automobile electric booster steering system.
Background technique
The electric power steering design adopts sensor insertion steering column to carry out ways of connecting, in order to reduce resistance, convenient for assembly, can use a spot of lubricating grease and be lubricated in the insertion process.But in practice, the grease segregation phenomenon take place because use the long period in the lubricating grease meeting, and part oil meeting flow sensor causes the short circuit of sensor, thereby directly influences the normal operation of sensor.
The model utility content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of protector for sensor of automobile electric booster steering system is provided, and plays the effect of flood protection wall, the danger of avoiding short circuit sensor to bring by setting up seal ring.
For realizing above-mentioned purpose, the protector for sensor of a kind of automobile electric booster steering system described in the utility model comprises seal ring, and described seal ring is arranged on the sensor, and described sensor inserts the steering column of automobile electric booster steering system.
Preferably, described seal ring is V-shaped seal ring.
Preferably, described seal ring is hollow cylinder, and the groove of V-type is set on the outer side surface of described seal ring.
Preferably, described sensor passes described seal ring.
The utlity model has following beneficial effect: the electric power steering design adopts sensor insertion steering column to carry out ways of connecting, the utility model is after having increased seal ring, can play the effect of flood protection wall, stop lubricating grease because the long-term part oil that takes place after grease separates that uses flow into sensor, influence the normal operation of sensor.The utility model is simple in structure, and is convenient and practical.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model sectional drawing;
Fig. 3 is the utility model assembly structure schematic representation.
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, 2, present embodiment provides a kind of protector for sensor of automobile electric booster steering system, comprises seal ring 1, and described seal ring 1 is arranged on the sensor 3, and described sensor 3 inserts the steering column of automobile electric booster steering system.
In the present embodiment, described seal ring is V-shaped seal ring.
In the present embodiment, described seal ring 1 is hollow cylinder, and the groove 2 of V-type is set on the circle of the outer wall 4 of described seal ring 1.
As shown in Figure 2, the one side of described seal ring 1 is the plane, and the outer wall 4 of another side and inwall 5 are at angle.
As shown in Figure 3, sensor 3 in the automobile electric booster steering system passes described seal ring 1, in the process of inserting steering column, the oil that is used for after lubricated lubricating grease generation grease separates is just separated by described seal ring 1, do not go thereby can not flow to sensor internal, avoid so cause short circuit sensor etc. to influence the consequence of the normal operation of sensor.
The utility model can play the effect of flood protection wall after having increased this V-shaped seal ring, stop lubricating grease because the long-term part oil that takes place after grease separates that uses flow into sensor, influences the normal operation of sensor.The utility model is simple in structure, and is convenient and practical.
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.
Claims (5)
