(57) [Abstract] [Purpose] In a power transmission clutch, the conventional method for connecting or disconnecting two plates is
The present invention has a drawback that it cannot be connected until the gear switching is completed and the power transmission is interrupted. The present invention aims to shorten the interruption time. [Structure] In a clutch, passive plates (4) and (5) having independent rotating shafts (6) and (7) are provided on both side surfaces of a drive plate (3) independently of each other. It is arranged so that it can be connected or disconnected in 3).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention aims to shorten the disengagement time of the power transmission clutch.

[0002]

[Prior art]

 A conventional clutch connects or disconnects two facing plates to intermittently transmit power.

[0003]

[Problems to be solved by the device]

 The conventional method of connecting and disconnecting two plates has a drawback that when the gears are switched, they cannot be connected until the gear switching is completed, and power transmission is interrupted. It was designed to save time.

[0004]

[Means for Solving the Problems]

 In the clutch, passive plates (4) and (5) having independent rotating shafts (6) and (7) are connected to the drive plate (3) independently on both sides of the drive plate (3). , Place it so that it can be separated.

[0005]

[Action]

 Normally, power is transmitted from the drive plate (3) to the output shaft (8) via one of the passive plates and its rotary shaft and gear, and when changing the gear, the other passive plate is driven. Separate it from the moving plate (3) and connect any gear on the rotating shaft to the gear of the output shaft (8) (during this time, the power is transmitted from the other passive plate through the existing gear to the output shaft). (They continue to be sent to (8)), and then the connected passive plate is disconnected from the drive plate (3), and at the same time, the disconnected passive plate is connected to the drive plate (3) to change the gear. Complete.

[0006]

EXAMPLES Examples of the present invention will be described below. In the clutch, passive plates (4) and (5) having independent rotating shafts (6) and (7) are provided on both sides of the drive plate (3) independently in the direction of the rotating shaft. After that, each rotary shaft is arranged so that it can be connected to and disconnected from the drive plate (3). Each rotary shaft has a gear with a different number of teeth in sequence (eg, in the case of 4 stages, the rotary shaft A (6) has a first speed). 3rd speed, 2nd speed for rotation axis B (7), 4th speed) Alternately using two rotation axes.

The present invention is configured as described above, and normally, the drive plate (3) is sandwiched by two passive plates from both sides, and the friction causes frictional rotation of the drive plate (3) to rotate integrally with one of the rotary shafts through a gear. When transmitting power to the output shaft (8) and changing the gear, disconnect the passive plate with the rotary shaft that is not transmitting power from the drive plate (3), and remove any gear on that rotary shaft. Connect to the output shaft gear (While the other passive plate is being pressed against the drive plate (3) during this time, continue to send power to the output shaft (8) via its rotary shaft and the current gear. Then, the connected passive plate is disconnected from the drive plate (3) at the same time, the disconnected passive plate is connected to the drive plate (3), the gear change is completed, and the separated passive plate is disconnected. Disconnect the gear that was transmitting power from the rotating shaft of the output shaft (8) from the gear After separating, the passive plate is connected to the drive plate (3), the drive plate (3) is sandwiched between the two passive plates again, and the gear change is completed. The same applies when electromagnetic force is used instead of friction to connect the drive plate (3) and the passive plates (4) and (5).

[0008]

[Effect of device]

 Since the present invention has the above-mentioned configuration, it has the following effects. If the gear change is performed using the double clutch of the present invention, the gear change can be performed in a short time regardless of the skill of the user, so that smooth and efficient running can be performed, and the passive plate drive plate (3) By connecting the intermittent operation to the gear shift operation and arranging the centrifugal clutch in front of this clutch mechanism, it is possible to realize a speed change mechanism that does not require clutch pedal operation with only shift operation.
