In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

The utility model provides a kind of speed probe, comprises a probe, and the first end of described probe is closeOne gear ring setting, the first end of described probe comprises an operative end surface; Also comprise:

Protective sleeve, the side surface of the first end of sheathed described probe;

The operative end surface of described probe is exposed, a reserved gap between described protective sleeve and described gear ring.

Furthermore, in described speed probe, described protective sleeve comprises the body of a column, described inOn body, offer a through hole, the operative end surface of described probe is stretched out and is exposed from described through hole.

Furthermore, in described speed probe, on the sidewall of the first end of described body, be provided with protrudingEdge.

Furthermore, in described speed probe, the shape of described through hole and the first end of described probeShape corresponding.

Furthermore, in described speed probe, described body adopts stainless steel material to make.

The utility model also provides a kind of automobile, comprises the speed probe described in as above any one.

Furthermore, in described automobile, also comprise mounting bracket, on described mounting bracket, offer peaceDress hole, the protective sleeve of described speed probe inserts in described installing hole, and the probe of described speed probe is insertedEnter in described protective sleeve.

The beneficial effects of the utility model are: speed probe of the present utility model, increases and protect at its probe placeSheath, can effectively reduce the probe of speed probe by the risk of F. O. D, thereby increased drivingSecurity, and reduced the possibility of keeping in repair.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and toolBody embodiment is described in detail the utility model.

Shown in Fig. 2, the utility model provides a kind of speed probe, comprises a probe 1, probe1 first end arranges near a gear ring 2, and the first end (lower end in diagram) of probe 1 comprises a jobEnd face 11; Speed probe also comprises: protective sleeve 3, the side surface of the first end of sheathed probe 1; Probe1 operative end surface 11 is exposed, a reserved gap L between protective sleeve 3 and gear ring 2.

In the time snapping in the hard things such as stone in the groove of gear ring 2, stone is driven by gear ring 2, stone motionTo near probe 1 bottom time, stone can first collide with protective sleeve 3, thereby has protected probe1 avoids damaging. Wherein protective sleeve 3 can adopt the materials such as stainless steel to make. It should be noted that, at probe1 outer setting baffle plates etc. are set-up mode similarly, can realize equally the object of protection probe 1, similarScheme also, in protection domain of the present utility model, does not enumerate at this. In addition, in order to reduce protective sleeve3 because the reasons such as vibrations cause interference to gear ring 2, between gear ring 2 and the lower end of protective sleeve 3, leave oneGap L.

Shown in Fig. 2, Fig. 3 and Fig. 4, protective sleeve 3 comprises the body 30 of a column, on body 30Offer a through hole 32, the operative end surface 11 of described probe 1 is stretched out and is exposed from described through hole 32. ThisOn the sidewall of the first end of body 30, be provided with flange 31, when flange 31 is convenient to install and on mounting bracket 4The installing hole of the offering clamping that matches.

Wherein, the shape of through hole 32 is to be phase with the shape of the first end of the probe 1 of the sheathed protective sleeve of needsCorresponding. In the present embodiment, through hole 32 comprises the hole section that multistage aperture is different, and each sector hole Duan Gong establishes at centerPutting, is successively decreased to the other end by the first end of body 30 in the aperture of every sector hole section, and through hole 32 forms stepped.The side of the first end of probe 1 is stepped equally. Like this, the shape of through hole 32 with probe 1 need byThe shape of the part of protection adapts, the convenient socket that matches with probe 1. Certainly the shape of through hole 32,Can make different changes according to the shape of probe 1, not enumerate at this.

The utility model also provides a kind of automobile, comprises the speed probe described in as above any one.

Shown in Fig. 2, automobile also comprises mounting bracket 4, on mounting bracket 4, offers installing hole, firstExpand former installing hole, the protective sleeve of multidiameter shape 3 is pressed in it, then by the probe of speed probe 1Pack in protective sleeve 3 and be fixed.

It should be noted that, this automobile is the automobile that comprises above-mentioned speed probe, and above-mentioned speed probe is realExecute in the embodiment that routine implementation is equally applicable to this automobile, also can reach identical technique effect,This repeats no more.

Above-described is preferred embodiment of the present utility model, should be understood that general for the artLogical personnel, can also make some improvement and profit not departing under principle prerequisite described in the utility modelDecorations, these improvements and modifications are also in protection domain of the present utility model.
