Embodiment 1

[0044] Embodiment 1: Single-switch type fast-acting spatial wedging centrifugal clutch CC10

[0045] Figure 1~3 Shown is a first embodiment of the present invention, which includes a force limiting element 180 formed around the axis X and having an axial force sealing function. The force limiting element 180 is preferably an annular pocket-shaped member, and the axial middle part of the inner peripheral surface 84 formed around the axis X is coaxially provided with a disc-shaped annular circumferential groove that is preferably planar. 78. The inner surface of about half of the circumferential groove 78 preferably extends to the outer peripheral surface of the force limiting element 180 along two mutually parallel tangential directions H and H′, and forms a rectangular inlet 82 with equal cross-section. The radially inner surface 80 of the circumferential groove 78 thus extends into a non-closed inner radial surface with a U-shaped cross-sectional shape and forms two mutual...

Embodiment 2

[0090] Embodiment 2: Multi-switching type fast-acting spatial wedging centrifugal clutch CC20

[0091] Such as Figure 5-6 As shown, the second embodiment is a direct modification of the first embodiment.

[0092] First, in order to realize small-diameter wheel-shaft transmission, the second shaft 210 is eliminated, and the gear teeth 168 are directly formed on the outer peripheral surface of the end flange 187 extending from the outer end surface of the disk-shaped end portion 188b.

[0093] Secondly, in order to obtain multi-switching capability, the centrifugal actuation mechanism CM is modified into a pin-slot guide rod mechanism. Wherein, all rod-shaped bases of the guide rod 20 are slidably disposed in the radial reference straight guide groove 22 on the support end surface 189 , and optimally do not contact the support end surface 224 . The outer peripheral surface of the arc-shaped block 26 located at the radially outer end of the guide rod 20 is provided with a circ...

Abstract

The invention discloses a centrifugal clutch, which comprises a full contact type self-excitation space wedge mechanism which is irrelevant to centrifugal force, a rotary guide type stepless supporting mechanism for driving a wedge mechanism to wedge or remove the wedge in a trigger mode, and a centrifugal actuating mechanism which responses to the centrifugal force to actuate the supporting mechanism. The clutch has high-intensity torque capacity irrelevant to the rotating speed and accurate and sensitive responsiveness; and moreover, the working conditions can be circularly changed along with monotonous ascending or descending of the rotating speed. When the clutch is used for a dual clutch transmission, the centrifugal clutch can adaptively finish gear-shifting operations of all forward gears, and any operating gear-shifting mechanism is not required. When the dual clutch is a space wedge type friction clutch, the whole complex and expensive hydraulic system can be completely abandoned; and meanwhile, because the gear-shifting operation is not required, the operating mode of the transmission is simplified, only the output rotating speed is required to be detected, and a secondary clutch which corresponds to the dual clutch in the dual clutch is engaged according to the rotating speed.
