CN2878807Y - Engine gear box cap for sand vehicle - Google Patents

Abstract

The utility model discloses a gear box cover of sand vehicle motor, comprising a cover body (1). A canister-shape flange (1b) is stretched out from the end surface of the cover body (1) and an installation hole for an output shaft (1c)is opened at the end surface of the canister-shape flange (1b). The installation hole for the output shaft (1c) is communicated to the inside cavity (1a) of the cover body (1). While assembling, the out-end of the output shaft (1c) is put in through the installation hole, and then be connected to a chain wheel which is close to the out-end of the canister-shape flange, so that the disadvantage result from the long cantilever of the output shaft existing between the chain wheel and the end surface of the cover can be cleared up, and the use life of the output shaft can be guaranteed.

Description

The dune buggy engine transmission-case cover

Technical field

The utility model relates to a kind of beach buggy, especially the dune buggy engine transmission-case cover.

Background technique

At present, the end face of general dune buggy engine transmission-case cover has the output shaft mounting hole, and output shaft passes from this hole, its outer end suit sprocket wheel.Because sprocket wheel and case lid end face have bigger spacing, promptly the cantilever of output shaft between sprocket wheel and case lid end face is longer, and beach buggy is under abominable operating mode, and the bracketed part of output shaft ruptures easily, can not get its working life ensureing.

The model utility content

For solving above technical problem, the purpose of this utility model is to provide a kind of dune buggy engine transmission-case cover that can effectively prevent the output shaft fracture.

The technical solution of the utility model is as follows: a kind of dune buggy engine transmission-case cover, comprise the case lid body, its key is: the end face of described case lid body extends the tubular boss laterally, end face at the tubular boss has the output shaft mounting hole, and this output shaft mounting hole communicates with the internal cavities of case lid body.

On the case lid body end face of above-mentioned tubular boss outside, be provided with a circle rosette, be distributed with stiffening plate between the end face of described case lid body and the rosette and between this rosette and the tubular boss.

Above-mentioned case lid body and tubular boss, rosette and stiffening plate are structure as a whole.

Adopt above technological scheme, the output shaft outer end passes from the output shaft mounting hole, behind the suit sprocket wheel, has only very little distance between sprocket wheel and the tubular boss, thereby eliminated because of the long disadvantage that exists of output shaft cantilever between sprocket wheel and case lid end face, ensured the working life of output shaft.

The beneficial effects of the utility model are: it can be at beach buggy and prevent effectively under the bad working environments that output shaft from rupturing, and has prolonged the working life of output shaft greatly, has advantages such as simple in structure, that enforcement is easy.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the right elevation of Fig. 1.

Fig. 3 is the A-A sectional view of Fig. 1.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As Fig. 1, Fig. 2 and shown in Figure 3, the end face of case lid body 1 of the present utility model extends tubular boss 1b laterally, has output shaft mounting hole 1c at the end face of tubular boss 1b, and this output shaft mounting hole 1c communicates with the internal cavities 1a of case lid body 1.During assembling, after output shaft mounting hole 1c was passed in the output shaft outer end, the suit sprocket wheel had only very little spacing between the exterior edge face of this sprocket wheel and tubular boss 1b again, thereby can prevent effectively that output shaft from rupturing.

From Fig. 1, Fig. 2 and Fig. 3, also can further find out, on case lid body 1 end face of tubular boss 1b outside, be provided with a circle rosette 1d, play the beautiful decoration effect, make the moulding of case lid body 1 have aesthetic feeling more; Be distributed with 6 stiffening plate 1e between the end face of described case lid body 1 and the rosette 1d and between this rosette 1d and the tubular boss 1b, and case lid body 1 is structure as a whole with tubular boss 1b, rosette 1d and stiffening plate 1e.Be connected firmly between rosette 1d and tubular boss 1b and the case lid body 1 like this, whole case lid can be by the injection moulding once-through.

Claims (3)

1, a kind of dune buggy engine transmission-case cover, comprise case lid body (1), it is characterized in that: the end face of described case lid body (1) extends tubular boss (1b) laterally, end face at tubular boss (1b) has output shaft mounting hole (1c), and this output shaft mounting hole (1c) communicates with the internal cavities (1a) of case lid body (1).

2, dune buggy engine transmission-case cover according to claim 1, it is characterized in that: on case lid body (1) end face of tubular boss (1b) outside, be provided with a circle rosette (1d), be distributed with stiffening plate (1e) between the end face of described case lid body (1) and the rosette (1d) and between this rosette (1d) and the tubular boss (1b).

3, dune buggy engine transmission-case cover according to claim 2 is characterized in that: described case lid body (1) is structure as a whole with tubular boss (1b), rosette (1d) and stiffening plate (1e).
