Description
Technical field
The utility model relates to clutch for motorcycle, relates in particular to wet clutch.
Background technique
Clutch is the vitals of connecting engine and speed changer, its Main Function is to realize motion between engine drive shaft (being bent axle) and driven shaft (being transmission main shaft) and transmission and the disengaging of power, guarantee engine power steadily reliably output with thoroughly promptly separated, to meet the needs of motorcycle starting, speed change, braking and parking.
In motorcycle wet clutch, there is a clutch housing, on it, be fixed with driven gear, on this clutch housing, be provided with center attachment hole, and this attachment hole matches by spline with the starter receiver on transmission main shaft, and make driven gear and the driving gear engagement being connected on bent axle, thereby realize the transmission of power between engine crankshaft and transmission main shaft.Meanwhile, because clutch constantly carries out the periodic duty of separation-joint-separation-joint under the different operating modes of vehicle, therefore, in the using process of wet clutch, the attachment hole of clutch housing and spline thereof will bear great impact force, torsion.
And a kind of clutch housing in wet clutch under prior art, its cover body adopts aluminum alloy material (lightweight and cost is low), and directly machine shaping on this cover body of the spline arranging on attachment hole and hole wall thereof, because the intensity of aluminum alloy material is poor, thereby in clutch working procedure, often there is the situation that spline large footpath change can not be felt relieved greatly, flank suffers destructive impact wear simultaneously, finally may cause motor cisco unity malfunction and life of clutch to shorten the consequence of even scrapping.
The problem existing for this kind of clutch housing of prior art, can be the material that strength ratio aluminum alloy is large by cover material integral replacing, but can obviously increase cost like that; Also attachment hole and spline can be arranged on driven gear (intensity of its material is greater than aluminum alloy), again driven gear is fixed on (Chinese patent that the clutch housing of this form can be CN203114940U referring to publication number) on aluminum alloy cover body, same problem, such one is to increase cost of material, the 2nd, and its manufacturing process is more complicated.Therefore, the utility model need to propose a kind of attachment hole and spline and cover body thereof and is made as one and increased clutch housing intensity, that manufacturing process is easy.
Model utility content
For achieving the above object, the utility model motorcycle wet clutch outer cover is improved like this: it comprises the cover body of aluminum alloy material and driven gear fixedly connected thereto, cover body is provided with the center attachment hole matching for the starter receiver with on transmission main shaft, hole wall along attachment hole is axially arranged with spline, its specialization is: attachment hole and upper spline thereof be arranged on a spline nested on, this spline is nested is cast into one with cover body, and the nested Material Strength of spline is larger than the material intensity of aluminum alloy of cover body.Further, the nested material of spline is restricted to cast iron.Because nested its Material Strength of such spline is greater than the intensity of cover body aluminum alloy, thereby directly on cover body aluminum alloy material, form attachment hole with prior art and spline is compared, the larger impact force from engine crankshaft and torsion can be born, thereby the object that the utility model increases attachment hole and spline intensity thereof can be effectively reached.Meanwhile, the blank that spline is nested and the founding of cover body one form, and the later stage is reprocessed into attachment hole and processes spline, cost of material increase less and manufacturing process simple and easy to do.
Optimally, on above-mentioned improved basis, on the nested periphery wall of spline, be provided with dispersedly groove or projection or both be provided with simultaneously.Further, in one end of the nested periphery wall of spline, be provided with annular recess one, be evenly distributed with annularly in the middle a plurality of projections.So arrange, make this spline nested with cover body founding when one, can effectively guarantee that spline housing becomes as a whole with cover body, the while also guarantees that itself and cover body bear integratedly from circumferentially, radially or the power of all directions such as axial.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model motorcycle wet clutch outer cover.
Fig. 2 be in Fig. 1 spline nested when the blank state (amplification) side view (attachment hole is not yet processed in hole wherein and its hole wall is not yet processed spline).
Embodiment
Only according to the specific embodiment providing, also by reference to the accompanying drawings the utility model is described below.
As shown in Figure 1, the motorcycle wet clutch outer cover 1 that the utility model is related, its main body is a cover body consisting of aluminum alloy material 2.This cover body 2 along level to extending to form a plurality of skirt sections 21 that also interval separates that are uniformly distributed, forms thus hood-like on the periphery of right side; Its left side is formed with a plurality ofly equally distributedly below will be addressed for driven gear 3(is installed circumferential) and the boss 22 of kit, each boss 22 center is provided with rivet hole (not marking in figure).At the axial centre position of this cover body 2, with cover body 2 coaxially, integrally casting has a spline nested 8 with holes; Hole on spline nested 8 be set to transmission main shaft on starter receiver (main shaft and starter receiver, all not shown in figure) suitable center attachment hole 7(is referring to Fig. 2), and the hole wall along this attachment hole 7 is axially formed with spline 83, spline (not shown) on spline 83 by (being on attachment hole 7 hole walls) on spline nested 8 and the starter receiver matching, cover body 2 is connected on starter receiver.In the present embodiment, the material selection cast iron of spline nested 8, its intensity is large compared with the material intensity of aluminum alloy of cover body 2 itself, can bear from larger impact force and the torsion of engine crankshaft (transmitting by driving gear, driven gear).Certainly, spline nested 8 also can select other intensity to be greater than the metal material of aluminum alloy, can reach this object equally.
On the right side of cover body 2, on each boss 22, be respectively set with a cushion collar 4, pass these cushion collars 4 and on attachment hole 7, be set with coaxially driven gear 3, one cover plates 5 with attachment hole 7 and pass rivet hole by rivet 6() driven gear 3 and cushion collar 4 thereof are fixedly connected on cover body 2.
Like this, by driven gear 3 and the engagement (bent axle and the driving gear that are connected in the driving gear on engine crankshaft, all not shown in figure), power from bent axle will be delivered to clutch housing 1, by spline 83, to starter receiver and transmission main shaft, transmit again, thereby can complete the power of engine crankshaft to the transmission of transmission main shaft.
Further, for guaranteeing that spline nested 8 and cover body 2 foundings are as a whole and making as a whole power of bearing from all directions, one end on nested 8 periphery walls of spline is provided with an annular recess 81, and be evenly equipped with in the middle in a plurality of protruding 82(the present embodiment circumferentially, it is 6, referring to Fig. 2).Certainly, for reaching same object, what on nested 8 periphery walls of spline, arrange can be a plurality of equally distributed independent grooves of disperseing, also can be multiple tracks annular recess, also can be a plurality of equally distributed separate convex of disperseing, also can be multiple tracks annular projection, can also be the applied in any combination of aforementioned independent grooves, annular recess, separate convex, annular projection.
The utility model also can have other to change on the basis of the present embodiment, only otherwise depart from the aim of the utility model improvement project, and all within the protection domain of the utility model claim.
