賽に挾持する様に設計されている。In order to uniformly control the output of machinery such as agricultural machines and construction machinery that are operated using internal combustion engines, etc., the clutch mechanism is usually assembled with an appropriate clutch mechanism. However, if such a structure is incorporated into the mechanical device of 1'), the operation will be complicated.Recently, the above-mentioned Il- has been combined to have two functions in one device. A stepless speed mechanism has been developed. □That is, wE
Figure 1 (during high-speed operation) and Figure 2 (during low-speed operation) are four schematic diagrams of a belt-type non-8V speed gutter, and Figure 6 conceptually explains the operation of the transmission. 1 is the input pulley, 2 is the output control pulley, and both of these Boo! An endless tape 8 of a certain length is wound between Jl m2' and the input pulley 1 (2) l! ! The Kll is configured to transmit one rotation to the output pulley 2 and rotate it. And input side day!
Jlll is made up of a movable @V-pla moved by a JIFi push rod 4 and a fixed lls/-pu Ib, and
The output pulley 2 is a movable wV-1 that is pressed by an insert spring 6.

J! When changing the position, move the push rod 4 in the direction of arrow A to bring the movable side V-plate 1a and the fixed @V-plane 1b closer together (from the horizontal position in Figure 2 to the folded position I in Figure 1). ).

ーの回転を出力側デー９２へ高ａ回転として伝達する。When both sheep la and lb come close to each other, a complement is applied to the outside N44111 of the input side boob v1 along the square groove 6 formed by the taber surface of the Peru 8FiV-pu 1m and lb, which is wrapped with the input side pulley IK. move. In other words, ′ in figure wg2: As shown (Outside m of output pulley 2: ’# IIK wrapped, 1k) 8 is pulled up above plane (2) as shown in figure 1, and this causes output K. Movable mechanism of side pulley 2 V-
The pipe 2a is pushed back in the direction of the arrow B-, and the gap between the V-shaped strips 6a becomes wider. As a result, the vehicle J&/) 8 is wound around the axis of the centrifugal unit 110 on the input side and the pulley on the output side, and transmits the rotation of the input pulley to the output side 92 as a high a rotation.

動される＊Ｋｌｌ成している。By the way, in order to push back the movable flAV-pull 2a in the direction of arrow B, it is necessary to apply a force stronger than the pressure of the push spring bO# to operate the push rod 4 (in the direction of arrow A). For this reason, in the past, a link mechanism as shown in No. 8 (2) was adopted, in which operating force was applied to the pedal 8 and the pushing pressure of the pushing rod 4 was applied to the pushing spring 6.
A speed transmission system has been proposed in which the pressure of the load can be applied to the toilet. That is, the pushing rod 4 is connected to the bed #8 via the connecting rod 9, and the pushing rod 4 is actuated by pressing the pedal 8.

8 for that! It requires a pedal depression force of 1.

が多い。However, with the link mechanism shown in Fig. 8, the amount of pedal depression is limited, and the lever ratio cannot be changed much due to the relationship with the pulley 8/foot amount, so the pedal depression force is limited. often exceeds normal human leg strength. In other words, as shown in the final rough of 4th W, as the pulley shifts, the pedal depression force (same #I) exceeds the pedal depression amount, which is influenced by the characteristics of the pressure spring b. This requires a stepping force that exceeds the standard human leg strength. Also, pedal depression force and odd J
l! As shown in V7 time threshold and Fi No. 6-, the time required for love speed V-ft is -1IX! Since there is a relationship between S and Beta A/depression force, when it is necessary to rapidly increase speed, Beda A/depression force often exceeds a person's standard leg force.

A movable sheep with a belt-type stepless f-tightness that allows the stepping force to be kept at or below the level at the start of the step even if the amount of stepping is large (lower than the standard human leg force). The purpose is to provide a pushing mechanism.

NO is the driving lever 16 and relay lever 16 before the pedal is depressed.
．． The positions of each of the driven levers are shown, and when the pedal is depressed to the maximum S position, these levers will move to QLhtM'O.
The position will be - If the stress of the depression force P at the connection point (M)K between the dynamic lever 16 and the relay lever 16 is pl, then a force of tjPl is applied to the relay lever 16. If the intersection angle between the driving lever 16 and the relay lever 16 is θ, then Pl=

To explain this by applying this to the diagram, when the force of Fl acts on point M at the start of depressing the pedal (line LMNO), the force of Fl is applied to the relay lever - (but when the pedal is depressed, the maximum increase is 1h). When (repetition LM'N' 0 ), the force acts point by point, and the other side P1 acts on the relay lever leB as a force F2.
即ちＦ２はＦｌの２倍以上となる。That is, F2 is more than twice Fl.

Therefore, the relationship between the amount of depression and the depression force in the movable sheep pusher 111aK of the present invention is based on the characteristics of the pressure spring 6 and the principle of lever. As shown in the curve, a large amount of lift is required, but if you reduce only the part that exceeds the standard leg force, the curve shown in Figure 4 will look like a broken line, and the depressing force will start to depress without making the shift amount that large. From the time until the end of the depression, y is constant, or if the depression is completed! It is also possible to lower it to 'nn.

! Even if the depressing force increases, the depressing force applied to the pedal by the 4-point brake increases as the pedal position increases, so it is difficult to increase the shift without taking a large V-foot amount.
