【考案の詳細な説明】
本考案は乾式の変速装置に用いられるＶベルト
に関する。[Detailed Description of the Invention] The present invention relates to a V-belt used in a dry transmission.
現在、自動車の走行用変速装置には歯車式変速
装置と油圧式変速装置が使用されている。これら
の長所を兼ね備えた変速装置として、操作性に優
れ且つ燃費の良いベルト式無段変速装置の開発が
進められている。 Currently, gear type transmissions and hydraulic type transmissions are used as driving transmissions for automobiles. As a transmission device that has these advantages, a belt-type continuously variable transmission device with excellent operability and good fuel efficiency is being developed.
このベルト式無段変速装置は、駆動軸と従動軸
に溝間隔が可変の変速プーリをそれぞれ取付け、
２個の変速プーリ間にＶベルトを巻掛けて構成
し、溝間隔を調整して回転ピツチ径を変化させ、
無段階に変速させるものである。 This belt-type continuously variable transmission has variable-speed pulleys with variable groove spacing installed on the drive shaft and driven shaft, respectively.
It consists of a V-belt wrapped between two speed change pulleys, and the rotation pitch diameter is changed by adjusting the groove spacing.
It allows the gears to be changed steplessly.
また、このベルト式無段変速装置には２種類が
あり、１つは金属Ｖベルトを使用する湿式の変速
装置（例えば特公昭55−6783号公報参照）であ
り、他方はゴムＶベルトを使用する乾式の変速装
置（例えば実公昭32−10408号公報参照）である。
一般に、変速プーリは鋳鉄、鋼、アルミニウム合
金等の金属材料で構成されるため、金属Ｖベルト
は摩擦面の焼付きや摩耗対策として潤滑油の中で
使用しなければならないが、ゴムＶベルトはその
必要がなくコストやメンテナンス面で有利であ
る。 There are two types of belt-type continuously variable transmissions: one is a wet type transmission that uses a metal V-belt (for example, see Japanese Patent Publication No. 1983-6783), and the other uses a rubber V-belt. This is a dry type transmission device (see, for example, Japanese Utility Model Publication No. 10408/1983).
In general, variable speed pulleys are made of metal materials such as cast iron, steel, and aluminum alloy, so metal V-belts must be used in lubricating oil to prevent friction surface seizure and wear, but rubber V-belts are This is not necessary and is advantageous in terms of cost and maintenance.
ところで、自動車の走行用変速装置は極めて高
トルクの伝動能力が要求される。例えば1000c.c.エ
ンジンの最大トルクをゴムＶベルトで伝達する場
合、Ｖベルトは20Kg／cm2前後の側圧力に耐えなけ
ればならない。 Incidentally, a transmission for driving an automobile is required to have an extremely high torque transmission capability. For example, when transmitting the maximum torque of a 1000 c.c. engine using a rubber V-belt, the V-belt must withstand a side pressure of around 20 kg/cm 2 .
しかしながら、現在、実用化されている標準的
なゴムＶベルトは、通常４〜５Kg／cm2以下で使用
され、高負荷用のゴムＶベルトにおいても10Kg／
cm2程度が限界である。この原因は、ゴムＶベルト
が高側圧において座屈変形し、Ｖベルトの発熱を
伴ない破壊されるためである。 However, the standard rubber V-belts currently in practical use are usually used at 4 to 5 kg/cm 2 or less, and even high-load rubber V-belts have a load of 10 kg/cm 2 or less.
The limit is around cm2 . The reason for this is that the rubber V-belt undergoes buckling deformation under high lateral pressure, and the V-belt generates heat and is destroyed.
そこで、考案者はエンドレスの一対の張力帯に

荷トルクにおいてＶブロツクが破損するという問
題が生じた。 Therefore, the inventor developed a V-belt (Patent Application No. 1983-1983), which is constructed by locking a plurality of roughly V-shaped blocks (hereinafter referred to as V-blocks) to a pair of endless tension bands.
139895), but since the V-block is made of non-metallic materials such as plastics and hard rubber for use in dry-type transmissions, the allowable stress of the V-block is smaller than that of metal blocks, resulting in high A problem arose in that the V block was damaged under the load torque.

グよりも小さいためである。 As shown in FIG. 2, a V-belt 1 according to the present invention
When the tension bands 2 and 3 are separated from the speed change pulley and are not receiving pressure, the side surfaces 2a and 3a of the tension bands 2 and 3 slightly protrude from the side surfaces 4a and 4b of the V-block 4, respectively. This is because the compressive Young's modulus of the tension bands 2 and 3 is normally the rubber member 8 reinforced with short fibers,
9, which is smaller than the compression Young of V block 4.

達力（伝動容量）も大きくなる。 FIG. 5 shows the power transmission state when the V-belt 1 engages with the speed change pulley 21 and receives side pressure.
The side surfaces 4a, 4b of the V-block 4 and the side surfaces 2a, 3a of the tension bands 2, 3 are each substantially on the same plane, and the friction transmission force with the speed change pulley 21 is generated on all the side surfaces. In this case, the side 4 of the V block 4
Since the plastics, hard rubber, etc. used for the friction blocks 13 and 14 forming the parts a and 4b have a large compressive Young's modulus, the V-belt can withstand high side pressure and has a large friction transmission force (transmission capacity).

ない。 When the V-belt 1 transitions from a separated state to an engaged state with the speed change pulley 21, the tension bands 2 and 3 engage with the speed change pulley 21 and receive a compression action, and then the V block 4 engages with the speed change pulley 21. match. At this time, the tension bands 2 and 3 alleviate the impact caused by the engagement between the V block 4 and the speed change pulley 21, so that the noise of the V belt 1 is reduced. Furthermore, since the reinforcing blocks 12 made of metal materials do not come into contact with each other, no impact sound is generated.

従つて、Ｖブロツク４および張力帯２，３に
は、厳しい寸法精度は要求されない。 Therefore, strict dimensional accuracy is not required for the V-block 4 and the tension bands 2 and 3.

ベルトが安価となる。 Further, the V-belt 1 is connected to the grooves 5 and 6 of the V-block 4.
The V-belt 1 is fixed in the length direction by the engagement of the protrusions or recesses provided on the tension bands 2 and 3 with the protrusions or recesses provided on the upper and lower surfaces of the tension bands 2 and 3, and is removable in the width direction. Therefore, installation is extremely easy, and V

い。 Furthermore, the V-block 4 is lighter and has less centrifugal force than a metal block, and is reinforced by the reinforcing block 12 and has high strength, so it is suitable for high-speed operation and high-load operation, does not break, and is safe. expensive.
張力帯２，３は、薄い平ベルト状をしているの
で、屈曲性は極めてよく、発熱も少ないのでベル

それもない。 In the present invention, as described above, since the V-block is constructed of a reinforcing block and a friction block, damage caused by high load torque can be prevented, extremely high side pressure can be applied, and a large frictional transmission force can be obtained. In addition, since one set of left and right friction blocks is engaged with the reinforcing block from both the left and right sides, it is possible to obtain a block with a large friction transmission force even with a simple structure to manufacture. Since the tension band is not in contact with the friction block, there is no fear that the tension band will break prematurely.
