Problems solved by technology

The problem with the existing centrifugal clutch 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
[0004] When the spring pulls the shoe back, the shoe will collide with the active part, causing the clutch to work unstable

Embodiment 1

[0035] like figure 1 As shown, the liquid-cooled buffer clutch structure includes a clutch housing 1, a runner 2, a shoe 3, a friction plate 4, a guide cylinder 5, a spring 6, a piston rod 8 and a piston 9; the runner 2 is set in the clutch housing 1 , the runner 2 is coaxial with the clutch housing 1, the runner 2 is evenly provided with at least three guide cylinders 5 in the radial direction, the number of the shoe blocks 3 is the same as that of the guide cylinders 5, and the shoe blocks 3 are provided with guide holes 301, the guide holes 301 is slidingly fitted with the guide cylinder 5, one end of the piston rod 8 is connected to the bottom of the guide hole 301, the other end of the piston rod 8 extends into the guide cylinder 5 and is connected with the piston 9, and a buffer space is formed between the piston 9 and the bottom of the guide cylinder 5. The buffer space is filled with hydraulic oil; the spring 6 is arranged between two adjacent shoe blocks 3, and the tw...

Embodiment 2

[0040] 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 .

[0041] 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...

Abstract

The invention discloses a liquid-cooling buffer-type clutch structure. A rotating wheel is arranged in a clutch shell. The rotating wheel and the clutch shell are arranged in an axial direction. At least three guide cylinders are uniformly arranged on the rotating wheel in a radial direction. Shoe blocks are provided with guide holes. The guide holes match with the guide cylinders in a sliding manner. One ends of piston rods are connected with bottoms of the guide holes. The other ends of the piston rods stretch into the guide cylinders to be connected with pistons. Buffer space is formed among the pistons and the bottoms of the guide cylinders. A spring is arranged between each two adjacent shoe blocks. Two ends of each spring are connected with two adjacent shoe blocks. Friction pieces are fixed on the outer cylindrical surfaces of the shoe blocks. The outer diameters of the friction pieces are the same as the inner diameter of the clutch shell. Accommodating cavities are formed in the shoe blocks and filled with water. The piston rods and the pistons are arranged. When the shoe blocks return to original positions, the pistons buffer hydraulic oil in the buffer space so that vibration caused by direct collisions between the shoe blocks and the guide cylinders is prevented. Working stability is improved. The liquid-cooling buffer-type clutch structure is further capable of preventing temperature of the friction pieces from rising too quickly.

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] Existing centrifugal clutches, such as the clutch disclosed in the invention patent application No. 201410498467, the centrifugal body includes two shoe blocks, the two ends of the two shoe blocks are connected by springs, and when the speed of the active part decreases, the pulling force of the springs Pull the shoe back to separate the shoe from the followe...
