Abstract
The utility model discloses a ship-shaped centrifugal sliding block which comprises a wear-resistant sliding body and a weight increasing piece, wherein the wear-resistant sliding body comprises an intermediate body, an inclined plane body formed at one end of the intermediate body and an arc-shaped body formed at the other end of the intermediate body, and the weight increasing piece is embedded on the intermediate body. According to the ship-shaped centrifugal sliding block, the inclined plane body of the ship-shaped centrifugal sliding block is in surface contact with the guide end cover, and the pressure intensity of the contact part is small, so that the abrasion speed of the inclined plane body can be reduced, and the service life of the ship-shaped centrifugal sliding block is greatly prolonged compared with that of an existing cylindrical centrifugal roller.
Description
Technical Field
The utility model relates to the technical field of a continuously variable transmission, in particular to a centrifugal piece in the continuously variable transmission.
Background
The existing continuously variable transmission commonly used for pedal motorcycles, as shown in figure 1 of the specification, an assembly part connected with a main shaft of an engine comprises a shaft sleeve 1, a fixed disc 2, a movable disc 3, a spring seat 4, a spring 5, a centrifugal roller 6 and a guide end cover 7, wherein the fixed disc and the guide end cover are respectively fixedly arranged at two ends of the shaft sleeve, the spring seat is fixed in the middle of the shaft sleeve, one end of an inner hole of the movable wheel is arranged on the spring seat through a sliding bearing, the other end of the inner hole of the movable wheel is arranged on the shaft sleeve through the sliding bearing, one end of the spring is propped against the spring seat, the other end of the spring is propped against the movable wheel, the centrifugal roller is arranged between the movable wheel and the guide end cover, the shaft sleeve is used for being connected with the main shaft of the engine, when the main shaft rotates in an accelerating manner, the centrifugal roller moves outwards and also moves along a guide inclined surface 8 on the guide end cover, so that the centrifugal roller pushes the movable disc to move axially, thereby changing the position of the transmission belt 9 on the fixed disc and the movable disc and achieving the purpose of changing the transmission ratio.
The existing centrifugal roller 6 is of a cylindrical structure, and is in line contact with a guide inclined plane 8 on a guide end cover, so that the contact area is small, and the technical problem of high friction and wear of the outer surface of the centrifugal roller is caused.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides a boat-shaped centrifugal slider to solve the technical problem of fast frictional wear of a cylindrical centrifugal roller in an existing continuously variable transmission.
The ship-shaped centrifugal sliding block comprises a wear-resistant sliding body and a weight increasing piece, wherein the wear-resistant sliding body comprises a middle body, an inclined plane body formed at one end of the middle body and an arc surface body formed at the other end of the middle body, the weight increasing piece is embedded on the middle body, the inclined plane body is in surface contact sliding fit with a guide end cover of a continuously variable transmission, the surface, in sliding fit with a moving wheel of the continuously variable transmission, on the arc surface body is a convex arc surface, and the weight increasing piece is embedded on the middle body.
Furthermore, the connecting structure further comprises a first reinforcing rib group for connecting the inclined plane body and the middle body and a second reinforcing rib group for connecting the middle body and the cambered surface body.
The utility model has the beneficial effects that:
according to the ship-shaped centrifugal sliding block, the inclined plane body of the ship-shaped centrifugal sliding block is in surface contact with the guide end cover, and the pressure intensity of the contact part is small, so that the abrasion speed of the inclined plane body can be reduced, and the service life of the ship-shaped centrifugal sliding block is greatly prolonged compared with that of an existing cylindrical centrifugal roller.

Detailed Description
The utility model is further described below with reference to the figures and examples.
As shown in fig. 2 to 3, the ship-shaped centrifugal slider of the present embodiment includes a wear-resistant slider 10 and a weight-increasing member 11, the wear-resistant slider includes a middle body 101, an inclined body 102 formed at one end of the middle body, and an arc body 103 formed at the other end of the middle body, the weight-increasing member is embedded on the middle body, the inclined body is in surface contact sliding fit with a guide end cover of the continuously variable transmission, a surface of the arc body in sliding fit with a moving wheel of the continuously variable transmission is a convex arc surface, and the weight-increasing member is embedded on the middle body.
The structure of the boat-shaped centrifugal slider mounted on the continuously variable transmission is shown in fig. 4, the boat-shaped centrifugal slider is arranged in a limiting groove on the moving wheel 3, the convex cambered surface of the cambered surface body 103 is in sliding fit with the groove bottom surface of the limiting groove, and the inclined surface body 102 is in sliding fit with the guide inclined surface on the guide end cover 7.
In this embodiment, the ship-shaped centrifugal slider is in surface contact with the guide end cover 7, so that the pressure at the contact part is small, the abrasion speed of the inclined plane body can be reduced, and the service life of the ship-shaped centrifugal slider is greatly prolonged compared with that of the existing cylindrical centrifugal roller.
As the improvement to the above-mentioned embodiment, still include the first strengthening rib group 12 of connecting the ramp body and middle part and the second strengthening rib group 13 of connecting middle part and cambered surface body, can avoid ramp body and cambered surface body bending deformation under pressure through setting up strengthening rib group to the assurance that can be better promotes and removes wheel 3 steady removal in the variable speed process.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
