産業上の利用分野
この発明は、トラクタ等の走行操作装置に関し、苗植機
、コンバイン等にも利用できる。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a travel control device for a tractor or the like, and can also be used for a seedling transplanter, a combine harvester, etc.
従来の技術、および発明が解決しようとする課題
走行ペダルを踏込むことによって変速走行を行う形態に
あっては、ブレーキペダルを踏んで一旦走行を停止して
も、次に走行ペダルを踏むと直ちに走行変速して発進す
るために、誤操作でこの走行ペダルを踏み易く、危険で
ある。Problems to be Solved by the Conventional Technology and the Invention In a system in which gear shifting is performed by depressing the travel pedal, even if the vehicle stops traveling once by pressing the brake pedal, the next time the travel pedal is pressed, the speed changes immediately. Since the vehicle shifts gears and starts moving, it is easy to press the travel pedal by mistake, which is dangerous.
課題を解決するための手段

。ブレーキペダル(1)を踏込むと。Functions and Effects of the Invention When the travel pedal (2) is depressed, the continuously variable transmission is increased in speed from the neutral position, and the vehicle travels at high speeds in accordance with the depression angle of the travel pedal (2). Loosen your foot and press the travel pedal (2)
When it returns, the vehicle is decelerated and returns to the neutral position, stopping the vehicle from running. When you press the brake pedal (1).

ている。The old neutral position return device consisted of a 7-shaped cam edge (9) formed at the upper end of the control arm (6) and a roller ( 111
The control arm (6) is configured to always return to the neutral position. (1 wheel is this roller (11)
This is an arm that is rotatably supported around 31. Both forward pedals (2F), reverse pedal (2R), and brake pedal (1) are provided rotatably around the pedal shaft (141) under the floor (4), and among these, the forward pedal (2F) rod ( 7) to the connecting arm (one is the pedal shaft f1
41, and the connecting arm (1ω) for the rod (8) of the reverse pedal (2R) projects shortly downward.

込量に対して前進変速よりも後進変速が小さい。When the forward pedal (2F) which has returned to the neutral position is depressed, the continuously variable transmission is sequentially increased in speed to the forward side in accordance with the depression angle. Also, if you release the forward pedal (2Y-'') and return it, the speed will be reduced and return to the neutral position, which is the non-transmission state.Also, if you press the reverse pedal (2R), the continuously variable transmission will start. The speed is increased sequentially to the reverse side, and when the pedal is released, the speed is decreased and returned to the neutral position.A pair of forward pedals (2F) and reverse pedals (2R) are When depressed, the other one protrudes toward the floor f411 in a reversible manner, and the backward shift is smaller than the forward shift for the same amount of depression.
