Description
Technical field
The utility model relates to a kind of four-wheel motor cycle, specifically refers to four-wheel motor cycle chain stay and rear axle housing body mounting structure.
Background technology
Rear axle assembly of four-wheel motor cycle comprises chain stay, rear axle housing body and hind axle etc., and chain stay mainly is made up of two chain stay limits pipe, chain stay central siphon, chain stay anchor ear and other annex again, and the chain stay anchor ear is provided with two pairs of locking journal stirrups.The chain stay central siphon is fixed by the overbolt and the vehicle frame that pass the chain stay central siphon, and rear axle housing body is positioned at the chain stay anchor ear and by the locking journal stirrup barrel bolt on the chain stay anchor ear rear axle housing body is held tightly.
Existing chain stay and rear axle housing body mounting structure have the following disadvantages:
1, chain stay anchor ear material is a steel plate, and steel plate is shaped to the anchor ear structure by make-up machine, often because the steel plate resilience is bigger, causes anchor ear to lose circle after the moulding, and it is difficult that the installation of rear axle housing body and chain stay anchor ear will become;
2, the locking journal stirrup by be welded on the chain stay anchor ear the connection journal stirrup be welded in the jam nut that is connected on the journal stirrup and constitute, connect journal stirrup and need mould molding, jam nut is welded on the connection journal stirrup simultaneously, so processed complex, loaded down with trivial details, the cost height;
3, be subjected to displacement between rear axle housing body and the chain stay anchor ear (chain stay) in order to prevent, between is provided with detent mechanism, and wherein rear axle housing body 5 is provided with draw-in groove 14, sees Fig. 1, and bolt passes when the locking journal stirrup is held rear axle housing body tightly and also passes from draw-in groove.Though this structure has been avoided both end float misalignments, the setting accuracy (welding) of locking journal stirrup is required high, otherwise bolt just can not pass from draw-in groove after passing the locking journal stirrup, perhaps passes very reluctantly, installation is difficult;
4, also be provided with back disc brake support on rear axle assembly of four-wheel motor cycle, back disc brake support one end is enclosed within rear axle housing body one end, and the back disc brake support other end is enclosed within chain stay limit pipe and goes up on the special back disc brake registration mast that is provided with.In order to prevent that back disc brake support from rotating, be arranged with the locating bush that has flat mouthful on the back disc brake registration mast, back disc brake carrying sleeve is on locating bush; For axial play after the disc brake support is installed after preventing, prior art only is provided with jump ring in the rear axle housing body outer end, by jump ring back disc brake support is tightened.But because back disc brake stent size is bigger, even back disc brake support one end chucking, end float misalignment also may take place in the back disc brake support other end (back disc brake registration mast place end), and it is unreliable to cause locating.
In addition, in the prior art, chain stay on rear axle housing body the location and the location of back disc brake support be independently, need location respectively, this makes the assembling of product seem loaded down with trivial details, influences efficient.
The utility model content
At the prior art above shortcomings, the purpose of this utility model is to provide a kind of simple in structure, chain stay and rear axle housing body location to be easy to four-wheel motor cycle chain stay and rear axle housing body mounting structure.
The utility model has also solved the chain stay anchor ear simultaneously and has lost circle and locking journal stirrup processed complex, loaded down with trivial details, problem that cost is high.
The purpose of this utility model is achieved in that a kind of four-wheel motor cycle chain stay and rear axle housing body mounting structure, it comprises chain stay and rear axle housing body, chain stay comprises chain stay anchor ear and chain stay limit pipe, the chain stay anchor ear is provided with double-type locking journal stirrup, and rear axle housing body is positioned at the chain stay anchor ear and by the chain stay anchor ear rear axle housing body is held tightly; Be arranged with back disc brake support and back disc brake support be clamped on chain stay anchor ear one end face at rear axle housing body one end by jump ring I, the back disc brake support other end is enclosed within chain stay limit pipe and goes up on the back disc brake registration mast that is provided with, it is characterized in that: the outer wall of the described rear axle housing body other end is provided with the positioning boss that chain stay anchor ear other end is located, on the disc brake registration mast of back, be provided with circular groove, be provided with jump ring II in the circular groove back disc brake support other end is tightened, between the jump ring II and the back disc brake support other end, be provided with waveform bullet pad.Chain stay is by positioning boss and jump ring location, and it is easier to locate, and has also reduced the setting accuracy of locking journal stirrup simultaneously.
Further, described chain stay anchor ear is a round steel pipe, is processed with vertically to regulate on round steel pipe to hold the logical breach of drawing of degree tightly.The distortion of chain stay anchor ear after the improvement is little, is beneficial to the installation with rear axle housing body, and round steel pipe processing simultaneously is easier.
Described each to locking journal stirrup constitute by two relative cylinders, two cylinders are separately fixed on the round steel pipe and are positioned at the breach both sides, one of them cylinder is processed with negative thread, and lock bolt passes a cylinder and is threaded with another cylinder rear axle housing body is held tightly.It is simpler that ear structure is propped up in improved locking, do not need mould molding, handling ease.
Compared to existing technology, the utlity model has following advantage:
1, the location of chain stay on rear axle housing body is easier, rear axle housing body passes from the chain stay anchor ear during installation, positioning boss on the rear axle housing body props up chain stay anchor ear one end, chain stay anchor ear other end is got final product by the chucking of the jump ring on the rear axle housing body, this jump ring is realized the chucking to back disc brake support simultaneously, has avoided the deficiency that the location of the location of chain stay and back disc brake support is carried out respectively;
2, the chain stay anchor ear adopts round steel pipe to process, and not only is out of shape for a short time, is beneficial to the installation with rear axle housing body, and round steel pipe processing simultaneously is easier;
3, the locking journal stirrup becomes a metallic cylinder by original connection journal stirrup and two parts of jam nut, structure is simpler, and does not need mould molding, and it is also easy to process, owing to there is not positioning requirements (not needing by the draw-in groove on the rear axle housing body), setting accuracy requires to reduce;
4, back disc brake support except on rear axle housing body by the jump ring location, when being connected, also be located by jump ring with back disc brake registration mast, locate more reliable.
