る不都合がある。 In an automatic two-speed transmission using gears, a low gear is used to rotate the driven shaft at low speeds, and a high gear is used to rotate the driven shaft at high speeds. And at this time,
A one-way joint is provided between the low gear and the driven shaft to overrun the driven shaft and cut off transmission with the low gear.
Generally, one-way joints are of the type where the roller bites into the tapered groove and transmits the transmission, but the tapered surface that is the contact surface of the roller becomes rough with use, so it does not slip. , it becomes difficult to set the taper angle, and its durability is poor. In addition, a device with interlocking claws has the advantage of ensuring reliable transmission, but has the disadvantage that when an overrun occurs, the claws move in and out, making noise each time.

に回転自在に軸架してある。 First, the mechanism of the automatic two-speed transmission will be explained with reference to FIG. engine crankshaft 1
A centrifugal clutch 2 is provided on one side of the motor, and the centrifugal clutch 2 is connected when the rotation increases to a certain extent. A low pinion 4 and a high pinion 5 are fixed to the driven side 3 of the centrifugal clutch 2, and mesh with a low gear 6 and a high gear 7, respectively. Low gear 6 is
The high gear 7 is mounted on a driven shaft 9 via a one-way joint 8, and the high gear 7 is mounted on a driven shaft 9 via a one-way joint 8.
0 to the driven shaft 9. and,
During low speed, the driven shaft 9 is rotated from the low gear 6 via the one-way joint 8. When the speed increases, the second centrifugal clutch 10 is connected and rotation is transmitted from the high gear 7 to the driven shaft 9 via the second centrifugal clutch 10. At this time, the driven shaft 9 is
can overrun compared to low gear 6. Therefore, in this device, as shown in FIG. 2, the present invention provides a threaded spline 13 on the outer periphery of a fixing fitting 12 which is fixed so as to mesh with a spline 11 provided on the driven shaft 9 and rotate together with the spline 11. will be established. Then, the annular metal fitting 14 is fitted to the fixing metal fitting 12 with a threaded spline. A meshing protrusion 15 is provided on one side of the annular metal fitting 14 and is opposed to a meshing groove 16 provided on the side surface of the low gear 6 so as to mesh with and disengage from it. Also, in low gear 6,
An elastic piece 17 such as an oil seal is attached, and the elastic piece 17 is brought into elastic contact with the annular metal fitting 14, so that the annular metal fitting 14 rotates together with the low gear 6 at low speeds when the centrifugal clutch 10 is in a disconnected state. be. Note that the low gear 6 and the high gear 7 are connected to the driven shaft 9
It is rotatably mounted on a shaft.

７は、環状金具１４の外周を軽く滑つている。 The annular metal fitting 14 is moved left and right in the axial direction by rotation due to the engagement of the threaded spline 13 with the fixing metal fitting 12 . And, it is always lightly braked by the elastic piece 17 so as to be attached to the low gear 6. Therefore, when power is transmitted by the low gear 6, the meshing protrusion 15 meshes with the meshing groove 16, as shown in the upper half, and the low gear 6, the annular fitting 14,
The rotation is transmitted to the fixing fitting 12 and the driven shaft 9, and the driven shaft is rotated. When the second centrifugal clutch 10 engages at high speed, rotation is transmitted to the high gear 7, the second centrifugal clutch 10, and the driven shaft 9. At this time, the fixing metal fitting 12 rotates faster than the low gear 6, so as shown in the lower half, the annular metal fitting 14 moves toward the high gear 7, the meshing protrusion 15 comes off from the meshing groove 16, and the low gear 6 becomes free. . At this time, the elastic piece 1
7 lightly slides on the outer periphery of the annular metal fitting 14.

て騒音が発生するようなこともない。 As explained above, this invention mounts the low gear that meshes with the low pinion on the driven shaft, through which the rotation of the high pinion is transmitted through the high gear and centrifugal clutch that mesh with the high pinion, and
A fixing fitting provided with a threaded spline on the outer periphery is fixed to the driven shaft on one side of the low gear, an annular fitting is screwed into the fixing fitting, and a mating protrusion provided on one side of the annular fitting is attached to the side of the low gear. The low gear is fitted with an elastic piece that makes elastic contact so that the annular fitting rotates together with the low gear at low speeds when the centrifugal clutch is not connected. Due to the difference in rotation of the driven shaft, the annular fitting moves in the axial direction, allowing the engagement protrusion and the dog in the engagement groove to engage and disengage. In this way, when transmitting in low gear, the dog engages and the driven shaft rotates, and when the driven shaft is rotated in high gear, the dog disengages and the low gear becomes free. Moreover, since it is a dog mesh,
The transmission is reliable, there is no slipping, and it is highly durable. Also, unlike nail biting, there is no noise caused by moving in and out when free.
