本発明は、Ｖベルト式無段変速機のドライブプーリに関
する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a drive pulley for a V-belt continuously variable transmission.
（従来の技術）
この種Ｖベルト式無段変速機は、駆動軸上に配されたド
ライブプーリと被動軸上に配されたドリブンプーリとの
間にＶベルトを巻掛けて構成され、駆動軸の回転速度に
比例（正確には回転速度の２乗に比例）してその値が大
きくなる遠心力を利用することによってベルト径を変え
、以て無段変速を行なうものである。(Prior Art) This type of V-belt type continuously variable transmission is constructed by winding a V-belt between a drive pulley placed on a drive shaft and a driven pulley placed on a driven shaft. The belt diameter is changed by utilizing centrifugal force whose value increases in proportion to the rotational speed (more precisely, in proportion to the square of the rotational speed), thereby achieving continuously variable speed.

）。By the way, the drive pulley is configured to include a fixed pulley half and a movable pulley half arranged on a drive shaft, and the movable pulley half is pressed by a flyweight operated by centrifugal force and driven together with a guide member. It slides in the axial direction of the shaft, thereby changing the distance between the two pulley halves and changing the rotation radius of the V-belt wound between the two pulley halves (for example, in Japanese Patent Application Laid-Open No. 47-1998). (See Publication No. 43847).

ボス部材との間にスティック（こじり）が生じた場合に
は１円滑な変速が阻害され、変速特性が悪くなるという
問題かあった。However, in the drive pulley of a conventional V-belt type continuously variable transmission, the guide member that guides the movable pulley half is fixed, so there is a stick between the guide member and the boss member through which it is inserted. When this occurs, smooth gear shifting is hindered, resulting in poor gear shifting characteristics.

ならしめるようにした技術が既に開示されている（特開
昭６２−１１００５６号公報参照）。Therefore, a technique has been developed in which the guide member is movably supported, so that when the stick occurs, the guide member can move in the axial direction together with the movable pulley half, thereby enabling smooth gear shifting. has already been disclosed (see Japanese Unexamined Patent Publication No. 110056/1983).

題も生じる。(Problem to be Solved by the Invention) However, in the above technology, the guide member is not necessarily held at the neutral position, and depending on the assembled state or operating state, the guide member may be located at the limit of movement. Therefore, the clearance on one side (the clearance formed between the end of the guide member and the support member) may become zero, and in such a case, the above-mentioned conventional problem can no longer be resolved, and smooth gear shifting may be hindered. This will cause the gear shifting characteristics to deteriorate. Also, spaces are formed outside both ends of the guide member to provide clearance, but if the guide member is a solid member, when the guide member moves, air, etc. in one space is compressed. As a result, the pressure within the space increases, which creates resistance to the movement of the guide member and hinders its smooth movement.

In the drive pulley of a V-belt type continuously variable transmission, the movable pulley half is slid in the axial direction of the rotating shaft together with the guide member using In addition to supporting the guide member, the guide member is characterized in that elastic means are housed in spaces formed outside both ends of the guide member.

性の悪化か効果的に防止される。(Function) Even if a stick occurs between the guide member and the boss member through which the guide member is inserted, the guide member is supported so as to be movable in the axial direction of the rotating shaft. It can move integrally with the pulley halves, achieving smooth gear changes as in the past. However, since the guide member is then returned to the neutral position by the resilient means disposed on both ends thereof, the guide member does not remain at its limit of movement and cannot move. A continuously variable transmission can achieve smooth shifting at all times, and effectively prevent deterioration of its shifting characteristics.

れている。By the way, between the movable pulley half 3 and the cover 7, a hollow round rod-shaped guide member 15 is horizontally suspended parallel to the rotating shaft 4 and movable in the axial direction of the rotating shaft 4. That is, as shown in detail in FIG. 1, groove-shaped bearing portions 16a and 17a each having a circular cross section are formed in the boss portions 16 and 17 that protrude from the inside of the movable pulley half 3 and the cover 7, respectively. Both ends of the guide member 15 are movably fitted and held in these bearing portions 16a and 17a, respectively. In each boss portion 16.17, a guide member 1 is provided.
Space parts S□ and S2 are formed on the outside of both ends of the guide member 5, and springs 18 and 19 are compressed to hold the guide member 15 in the neutral position. .

る。The guide member 15 is slidably inserted into the outer peripheral portion of the spider 9, and the portion of the spider 9 through which the guide member 15 is inserted is provided with a guide made of Teflon resin with high self-lubricating properties. A bushing 20 is fitted and held.
次に、ドライブプーリ１の作用を説明する。Next, the operation of the drive pulley 1 will be explained.

することによってなされる。When the engine is driven from the engine non-operating state shown by the solid line in FIG. 1 and the crankshaft 30 and rotating shaft 4 rotate, the fixed pulley half 2 and spider 9 connected to the rotating shaft 4 rotate together. . When the rotational speed of the rotating shaft 4 (crankshaft 30) increases beyond a predetermined value, the centrifugal force acting on the weight roller 13 of the flyweight 10 rotating together with the spider 9 increases, and the weight roller 13 In response to this, it rotates about the shaft 11 in the direction of arrow A in FIG. Then, this weight roller 13
The movable pulley half 3 having a cam surface 3a that engages with the cover 7 and the guide member 15 is pushed by the weight roller 13 and moves on the rotating shaft 4 against the elastic force of the spring 14 in the direction of the arrow in FIG. It moves in direction B, holds the V-belt 6 between the fixed pulley half 2, and transmits rotational power to the driven pulley (not shown) via the V-belt 6. The sliding movement between the movable pulley half 3 and the cover 7 is guided by the guide member 15 sliding within the guide bush 20 of the spider 9.

増速されて伝わり、斯くて無段変速がなされる。When the rotational speed of the rotating shaft 4 further increases, the amount of rotation of the weight roller 13 of the flyweight 10 increases, and the movable pulley half 3 further moves in the direction B as shown by the chain line in FIG. As the belt 6 is pushed outward in the circumferential direction, the diameter (rotation radius) of the belt 6 that wraps around the drive pulley 1 becomes larger, and conversely, the diameter of the belt 6 that wraps around the driven pulley becomes smaller, and as a result, there is no rotation on the driven pulley side. is transmitted at increased speed, thus achieving continuously variable speed.

現される。In the above operation, the guide bush 20 of the spider 9 and the guide member 1 due to deformation of the member due to thermal expansion, etc.
Even if a stick occurs between the guide member 15 and the movable pulley half 3 (and the cover 7), since the guide member 15 is supported movably in the axial direction of the rotating shaft 4 as described above, the guide member 15 and the movable pulley half 3 (and the cover 7) As shown in FIG. 2, they can move together against the elastic force of the spring 19, and smooth gear shifting can be achieved as in the conventional case.

とができることとなる。However, in this embodiment, the guide member 15 is then moved by springs 18 and 19 disposed at both ends thereof.
Since the guide member 15 is returned to the neutral position by the spring 19 (in the above case), the guide member 15 does not remain at its limit of movement and cannot move, thereby ensuring that the V-belt continuously variable transmission always operates smoothly. Therefore, a speed change is realized, and deterioration of the speed change characteristics is effectively prevented. Furthermore, as described above, since the blue space parts S I and S t are communicated with each other through the through hole 15 a of the guide member 15 , as shown in FIG. Even if it moves, the volume of air, oil, etc. corresponding to this movement flows from the space S2 through the through hole 15a into the other space S, as shown by the arrow a, so that the internal pressure of the space S2 decreases. This means that the guide member 15 can move freely without resistance.
