Abstract

The utility model discloses a centrifugal friction clutch. An input end of the centrifugal friction clutch is connected with a driving shaft and an output end of the centrifugal friction clutch is connected with a driven shaft. The centrifugal friction clutch comprises a driving shaft semi-clutch, a driven shaft semi-clutch, a centrifugal block and a spring, wherein the driving shaft is connected with the driving shaft semi-clutch; the driven shaft is connected with the driven shaft semi-clutch; the driving shaft semi-clutch and the driven shaft semi-clutch are of hollow cylinders; the driving shaft semi-clutch is located in the driven shaft semi-clutch; and one end of the spring is connected with a shaft center of the driving shaft semi-clutch and the other end of the spring is connected with the centrifugal block. According to the centrifugal friction clutch disclosed by the utility model, the clutch can be automatically closed and separated through a rotating speed difference of the driving shaft, a phenomenon that the slipping is generated and separation is not complete does not happen and the service life is long.

Description

Centrifugal friction clutch

Technical field

The utility model relates to a kind of clutch, relates in particular to a kind of centrifugal friction clutch.

Background technique

So-called clutch is as the term suggests utilize " leaving " and " closing " to transmit an amount of power in other words.Clutch can produce and skid, separate phenomenons such as not thorough.The reason that generation is skidded has that separator levers is out of shape, fractures, serious wear; The clutch driven plate warpage, rivet gets loose, and the new clutch friction plate of perhaps changing is blocked up; Clutch driven plate positive and negative dress is anti-; Clutch plate hub keyway and clutch spindle spline tooth gap are too small or block, and cause and move difficulty.The bad main cause of clutch separation is that the free travel of clutch pedal is too big.After changing clutch driven plate besides, owing to ignored the cleaning to clutch spindle, impurity is arranged, cause clutch plate hub and first gap too small, moving resistance is big, and clutch separation is bad.

Existing clutch kind is a lot, but from skidding and separating halfway phenomenon, has reduced the working life of clutch.

Summary of the invention

The purpose of the utility model with regard to be to provide in order to address the above problem a kind of volume little, be easy to make, clutch separation centrifugal friction clutch completely.

The utility model is realized above-mentioned purpose through following technological scheme:

The utility model comprises driving shaft, driven shaft, friction plate, the half-clutch device of driving shaft and the half-clutch device of driven shaft; It is characterized in that: also comprise centrifugal and spring; Half-clutch device of said driving shaft and the half-clutch device of said driven shaft are hollow circular cylinder; The half-clutch device of said driving shaft is positioned at the half-clutch device of said driven shaft, and an end of said spring is connected with the axle center of the half-clutch device of said driving shaft, and the other end of said spring is connected with said centrifugal.

Particularly, said spring is a draught spring; Said centrifugal is centrifugal of aluminum; The inwall of the half-clutch device of driven shaft is the steel friction plate;

Further, the gap between half-clutch device of said driving shaft and the half-clutch device of said driven shaft is 8mm;

Further, said centrifugal is 4, is evenly distributed on the circumference in the half-clutch device of said driving shaft axle center.

The beneficial effect of the utility model is:

The utility model is realized clutch through the speed drive shaft difference auto-closing with separate, can not producing skids separates halfway phenomenon, precise control is easy to use, and can not produce to skid and separate halfway phenomenon, and the life-span is long.

Description of drawings

Fig. 1 is the partial sectional view of the utility model;

Fig. 2 is the A-A sectional view among Fig. 1.

Among the figure: 1-driving shaft, the half-clutch device of 2-driving shaft, 3-centrifugal, the half-clutch device of 4-driven shaft, 5-driven shaft, 6-draught spring.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As depicted in figs. 1 and 2; The utility model comprises centrifugal 3 and draught spring 6; The half-clutch device 2 of driving shaft is hollow circular cylinder with the half-clutch device 4 of driven shaft; The half-clutch device 2 of driving shaft is positioned at the half-clutch device 4 of driven shaft, and an end of draught spring 6 is connected with the axle center of the half-clutch device 2 of driving shaft, and the other end of draught spring 6 is connected with centrifugal 3.

In conjunction with Fig. 2, the working procedure that the utility model carries out is following:

When 1, driving shaft 1 is turned back to certain speed, will throw away attached to centrifugal 3 on the half-clutch device 2 of driving shaft;

2, be pressed on the inner cylindrical surface of the half-clutch device 4 of driven shaft after being thrown out of for centrifugal 3;

3, centrifugal 3 and the half-clutch device 2 interior wall frictions of driving shaft rotate driven shaft 5;

4, driven shaft 5 rotating speeds reduce clutch separation when perhaps stopping.
