Description

The upper plate of clutch of motorcycle, lower plate combination

One, technical field

The utility model relates to a kind of upper plate, lower plate combination of clutch of motorcycle parts, particularly clutch of motorcycle.

Two, background technique

Motorcycle is starting, parking, clutch is all extensively adopted in safety traffic, in clutch, be provided with upper plate, the lower plate combination on friction plate combination and both sides thereof, support release spring provided thereon by upper plate, lower plate combination grip, make up compression and release by upper plate, lower plate to release spring, make between the friction plate in the clutch friction plate combination in conjunction with separate, realize the function of clutch.At present, the upper plate of clutch of motorcycle, lower plate combination are made of the guiding rivet of riveting on upper plate, lower plate and the plate thereof, rivet on it is riveted on upper plate, the lower plate after processing one by one again, complex structure, flow is long, use equipment and manpower are more in the manufacture process, and manufacturing efficiency is lower.

Three, summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and manufacture process is short, can reduce the consumption of manufacturing mechanism and manpower, the upper plate of the clutch of motorcycle of enhancing productivity, reducing production costs, lower plate combination.

The purpose of this utility model is to adopt following technological scheme to realize: a kind of upper plate of clutch of motorcycle, lower plate combination, be characterized in that upper plate, lower plate have the identical dentation plate body that is symmetrical annulus, tooth portion punching out at the upper and lower, left and right of upper plate plate body end has the positioning boss that exceeds plate body plate face, the riveted joint of relative position with the location plush copper of upper plate of the tooth portion of the upper and lower, left and right end of lower plate plate body has the guiding rivet, and it is 4.0-6.1mm that the guide end of guiding rivet exceeds lower plate plate body plate face length degree.

The length that positioning boss on the upper plate plate body exceeds upper plate plate body plate face is 0.8-1.3mm.

The upper plate of the clutch of motorcycle that provides by the utility model, lower plate combination, owing to take to formulate the position boss in the plate body upper punch of upper plate, need not make guiding rivet and riveted joint guiding rivet, with positioning boss release spring is positioned, leads, therefore simple in structure, manufacture process is short, be easy to processing, also reduced the consumption of manufacturing and processing equipment and manpower, improved manufacturing efficiency, reduced production costs.Length is 4.0-6.1mm because the guiding rivet on lower plate exceeds the plate body plate again, thereby can reach the working life of friction plate to greatest extent, has improved the functional reliability of clutch.

Four, description of drawings

The utility model has following accompanying drawing:

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

Fig. 2 is the partial view I among Fig. 1;

Fig. 3 is the partial view II among Fig. 1;

Fig. 4 is that the A of upper plate among Fig. 1 is to view;

Fig. 5 is that the B of lower plate among Fig. 1 is to view;

Schematic representation when Fig. 6 is the normal mounting state;

Schematic representation when Fig. 7 reaches greatest limit for the friction material wearing and tearing;

Schematic representation when Fig. 8 reaches the maximum separation stroke for clutch.

Among the figure: 1-upper plate 2-lower plate 3-release spring 4-wearing piece combination 5-positioning boss 6-guiding rivet

Five, embodiment

Embodiment of the present utility model is described with reference to the accompanying drawings, as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of upper plate of clutch of motorcycle, lower plate combination, be characterized in that upper plate 1, lower plate 2 have the identical dentation plate body that is symmetrical annulus, tooth portion punching out at the upper and lower, left and right end of upper plate 1 plate body has the positioning boss 5 that exceeds plate body plate face, there is guiding rivet 6 in the tooth portion of the upper and lower, left and right end of lower plate 2 plate bodys with the 5 relative position riveted joints of the location plush copper of upper plate, and it is 4.0-6.1mm that the guide end of guiding rivet 6 exceeds lower plate 2 plate body plate face length degree.

In aforesaid embodiment, the length that the positioning boss 5 on upper plate 1 plate body exceeds upper plate 1 plate body plate face is 0.8-1.3mm.

The distance between plates 9mm of upper and lower plate when the normal mounting state keeps positioning boss and guiding rivet head spacing to be no less than 1.6-2mm, as shown in Figure 6; When the clutch on-off number of times reaches 1 * 10 ⁶Inferior, when the friction material of friction plate combination 4 reaches wear limit (0.4/ single face), or friction plate is when making up 4 thickness and reaching limit inferior, the distance between plates that makes upper and lower plate is 7.6mm, the guiding rivet head spacing of the positioning boss of upper plate and lower plate still is no less than 0.2-0.6mm, can guarantee the clutch proper functioning, and reliability is guaranteed, friction plate is improved working life, as shown in Figure 7; When clutch reached maximum separation stroke distance between plates and is 12mm, release spring 3 free lengths were 11mm, can guarantee that still release spring 3 does not break away from positioning boss and guiding rivet, improves the functional reliability of clutch, as shown in Figure 8.
