Description

The totally-enclosed chain cover of motor bike

Technical field

The utility model relates to a kind of motor bike chain cover, particularly relates to the totally-enclosed chain cover of a kind of motor bike.

Background technology

At present, some motor bikes of selling on the market, its driving chain is exposed, and lubricating oil on the chain adheres to dust and silt easily outside, thereby quickens chain wear, influences its service life; The second, chain in the course of the work, the machine oil on it is shed on the way, contaminated environment; In addition, the degree of tension of chain is regulated trouble, easily takes off chain, in the time of its driving chain landing, tends to stuckly among the trailing wheel nut, causes safety misadventure easily.Chinese patent CN1164492A discloses a kind of chain cover of motor bike made of plastic, its formation is that chain cover is divided into upper and lower chain cover, two forks and combined hole and engagement pawl are established in the middle part of upper and lower chain cover, at back swing arm [or claiming chain stay] the insertion plate is set, be connected when also the insertion plate of the back swing arm of dependence assembles with above-mentioned y-bend portion and combined hole and engagement pawl between the upper and lower chain cover, thereby constitute a complete integral body.Can avoid many defectives of the exposed motor bike of driving chain though use the technical scheme of this patent, but need to change the structure of back swing arm, otherwise upper and lower chain is difficult to close up and can occurs being out of shape problems such as excessive, it assembles complicated, increased the manufacturing cost of frame of motorcycle, it promotes the use of difficulty.In addition, the length and width direction comparison of sizes as the motor bike chain cover is big, lateral dimension is less, and with the suitable easy deformation of plastic production, the lighter influences attractive in appearance, and is heavy then influence performance.

The utility model purpose

The purpose of this utility model is to provide a kind of motor bike totally-enclosed chain cover, this chain cover not only can avoid the exposed motor bike of driving chain many defectives, but also can overcome the deficiency of the chain cover easy deformation of plastic production.

The purpose of this utility model can reach by following technical measures, it is the totally-enclosed chain cover of this motor bike, comprise chain cover and bolt, it is characterized in that: described chain cover has box body behind the preceding box body,, on forward and backward box body, all offer axis hole, preceding box body is connected with anchor ear by elastic rubber sleeve with the back box body, and closes by preceding lid and back box cap seal respectively; Be provided with one and regulate bolt on the box body of back, regulate bolt and be connected with the axle that idler sprocket is housed, this idler sprocket is arranged in the inner chamber of back box body.

The tail end of box body has two anterior cannula before described, the front end bifurcated of described back box body, and the end of each bifurcated is provided with rear sleeve, and this rear sleeve is connected with cooresponding anterior cannula with anchor ear by elastic rubber sleeve.

In the axis hole on described forward and backward box body oil sealing is housed all.

Described back box covers and offers oil hole, in this oil hole bolt is housed, by being welded on the locking of oil hole nut outside.

The bottom of described back box body offers outage, in this outage bolt is housed, by being welded on the locking of outage nut outside.

According to the totally-enclosed chain cover of the above-mentioned motor bike that assembles, after being installed on the motor bike, the output chain gear of motor bike and driven sprocket lay respectively in the forward and backward box body, the driving chain that connects output chain gear and driven sprocket is sealed by chain cover fully, and in chain cover, add the notes lubricating oil, thereby can prevent effectively that the lubricating oil on the chain from adhering to dust and silt, reduce chain wear, prolong its service life; The second, chain in the course of the work, the machine oil on it can not shed on the way, has avoided environmental pollution; In addition, rotate and regulate bolt, promptly the may command idler sprocket moves on the adjusting bolt, and is very simple and convenient to regulate the degree of tension of chain, prevented effectively that also chain from taking off chain, and safety is good.Simultaneously, the utility model also has characteristics such as not yielding, good looking appearance, dependable performance, assembling be easy.
