Problems solved by technology

The problem with the existing centrifugal clutch structure is that the two ends of the two shoes are connected by springs, so that only two shoes can be arranged in the clutch, resulting in limited friction between the shoes and the follower

Embodiment 1

[0032] like figure 1 As shown, the centrifugal clutch structure includes clutch housing 1, runner 2, shoe block 3, friction plate 4, guide cylinder 5 and spring 6; runner 2 is set in clutch housing 1, and runner 2 is the same as clutch housing 1 The shaft and runner 2 are evenly provided with at least three guide cylinders 5 in the radial direction. The number of shoe blocks 3 is the same as that of the guide cylinders 5. Guide holes 301 are provided on the shoe blocks 3, and the guide holes 301 are slidably matched with the guide cylinders 5. The spring 6 is set in the guide cylinder 5, one end of the spring 6 is connected with the runner 2, the other end of the spring 6 is connected with the shoe block 3, and the friction plate 4 is fixed on the outer surface of the shoe block 3; the outer diameter of the friction plate 4 and the clutch The inner diameters of the shells 1 are the same; the shoe block 3 is provided with a housing cavity 302, and the housing cavity 302 is fill...

Embodiment 2

[0036] like figure 1 and figure 2 As shown, this embodiment is based on Embodiment 1. The friction plate 4 includes a connecting piece 401 fixed on the outer surface of the shoe block 3 and a friction part 402 fixed on the connecting piece 401. The friction part 402 The outer diameter of the friction part 402 is larger than the outer diameter of the connecting plate 401 , and the outer diameter of the friction part 402 is the same as the inner diameter of the clutch housing 1 .

[0037] In operation, the friction plate 4 is used for friction with the clutch housing 1, and the friction plate 4 is damaged quickly and needs to be replaced regularly. In order to facilitate the replacement of the friction plate 4, the friction plate 4 includes a connecting piece 401 fixed on the outer surface of the shoe block 3 and a friction part 402 fixed on the connecting piece 401, and the friction part 402 rubs against the clutch housing 1 during operation. After the friction force is redu...

Embodiment 3

[0039] like figure 1 and figure 2 As shown, this embodiment is based on Embodiment 2, and the friction part 402 is connected to the connecting piece 401 through bolts 7 .

Abstract

The invention discloses a centrifugal clutch structure. The centrifugal clutch structure comprises a clutch housing, a rotating wheel, shoe blocks, friction pieces, guide cylinders and springs. The rotating wheel is arranged in the clutch housing. The rotating wheel and the clutch housing are arranged on the same axis. The rotating wheel is uniformly provided with the at least three guide cylinders. The number of the shoe blocks is equal to that of the guide cylinders. Guide holes are arranged in the shoe blocks. The guide holes and the guide cylinders are slidably matched. The springs are arranged in the guide cylinders. One end of each spring is connected with the rotating wheel and the other end of each spring is connected with one shoe block. The friction pieces are fixed on the outer circular surfaces of the shoe blocks. The outer diameters of the friction pieces are the same as the inner diameter of the clutch housing. An accommodating cavity is arranged in each shoe block and filled with water. The springs are arranged in the guide cylinders. Each shoe block corresponds to a spring so that multiple shoe blocks can be arranged on the rotating wheels. Therefore, the number of the shoe blocks can be adjusted according to friction force provided according to the need. The centrifugal clutch structure helps the temperature of the friction prices from rising too fast.

Description

technical field [0001] The invention relates to a clutch. Background technique [0002] Centrifugal clutch transmits torque through friction, and its basic structure consists of three elements: driving part, centrifugal body and driven part. The centrifuge is slipped on the active part, and the prime mover drives the active part to rotate and accelerate to throw it out in the radial direction. When the driving part reaches the specified angular velocity, the thrown out centrifugal body is pressed against the inner wall of the driven part, and is forced into a motion state by friction force to transmit torque. [0003] In the existing centrifugal clutch structure, such as the clutch disclosed in the invention patent application number 201410498467, the centrifugal body includes two shoes, and the two ends of the two shoes are connected by springs. The pulling force pulls the shoe back, separating the shoe from the follower. The problem with the existing centrifugal clutch ...
