る。 An example of the drive side of a V-belt automatic transmission is shown in FIG.
As shown in the figure, a tube shaft 2 is supported on a drive shaft 1 such as an engine crankshaft, and is connected via a starting clutch consisting of a drive plate 3, centrifugal shoe 4, and driven drum 5. A drive V-pulley is formed by opposing a fixed face 6 and a movable face 7 that rotates integrally with the tube shaft 2 and is freely axially movable, and a V-belt 8 is hung on the drive V-pulley. An inclined surface 9 is formed on the back of the movable face 7, and a ramp plate 10 is fixed to the tube shaft 2 opposite the inclined surface 9.
The gap between the ramp plate 10 and the ramp 11 is set so as to narrow in the centrifugal direction, and a centrifugal roller 11 is interposed therebetween.

が多かつた。 When the rotation of the drive shaft 1 increases and the tube shaft 2 rotates via the starting clutch, the fixed and movable faces 6,
7 rotate together and transmit power to a driven V pulley (not shown) via a V belt 8. When the rotational speed further increases, the movable face 7 is pushed by the centrifugal force of the centrifugal roller 11, the diameter of the V-pulley increases, and finally, as shown in FIG. 2, power is transmitted at high speed. Next, there are the following problems when decelerating. That is, if the movable face 7 does not return properly due to some trouble during deceleration, the centrifugal roller 11 loses centrifugal force while remaining in the state shown in Fig. 2, loses its posture as shown by the chain line in the figure, and falls down, causing it to fall down again. Does not restore function. Generally, walls 12 are provided at both ends of the centrifugal roller 11 to guide the centrifugal roller 11, but in a structure where the movable face 7 moves a large amount, sufficient guidance is not possible, and the above-mentioned problems often occur. Ta.

と平行に貫通した長孔14を持つ。 First, a guide lever 13 is provided on the outer periphery of the back of the movable face 7, which is swingably supported by a tangential support shaft 12. The guide lever 13 extends in the centripetal direction, and the support shaft 12 extends along the longitudinal direction of its inner half.
It has a long hole 14 penetrating in parallel with.

接線方向に向けて移動する。 The centrifugal roller 15 is separated into two parts and connected by a rod 16 with a slight distance between them, with a circumferential groove 17 formed in the center. The circumferential groove 17 is fitted into the elongated hole 14 to slidably support the centrifugal roller 15 on the guide lever 13, and the centrifugal roller 15 always moves with its axis oriented in the tangential direction.

すことがない。 The centrifugal roller 15 at low speed is in the state shown in Fig. 3, and at high speed, the centrifugal roller 15 moves in the centrifugal direction as shown in Fig. 5. When the rotation is decelerated from this state to low speed, even if the return of the movable face 7 is delayed or jammed due to some trouble, the centrifugal roller 15 continues to maintain the normal position by the guide lever 13, so no functional failure occurs.

機を低コストに提供できる効果を有する。 As described above, the centrifugal weight support device for a V-belt automatic transmission according to this invention maintains a stable posture of the centrifugal roller by means of a swingable guide lever, and improves the operation of the V-belt automatic transmission. Make it stable. Furthermore, the amount of movement of the movable face, that is, the shift width can be increased, the degree of freedom in design is high, and the functions of the transmission can be greatly improved. Conventionally, it was necessary to increase the diameter of the centrifugal roller according to the amount of movement of the movable face, but with this device, the diameter of the centrifugal roller can be set regardless of the speed change width, which suppresses the overall size of the mechanism and makes it compact and high performance. This has the effect of providing a V-belt automatic transmission at low cost.
