Speed control system for a vehicle having a stepless transmission
First Claim
1. A speed control system for a vehicle having a stepless transmission, comprising:
- control means for controlling said stepless transmission, said control means including a rotatable shaft and attached drive arm displaceable within a first displacement region disposed to one side of a neutral position to drive the vehicle forward, and a second displacement region disposed to the other side of said neutral position to drive the vehicle backward;
a pivotable foot pedal shiftable between a first position and a second position;
a pivotable transmission means for transmitting a shift of said foot pedal to said drive arm through a rotation of said transmission means; and
forward-backward drive selecting means for acting on said transmission means, said forward-backward drive selecting means including a switch lever shiftable between a forward position, a reverse position and at least one forward drive position, said forward-backward drive selecting means switching said transmission means between a forward mode when said switch lever is in said forward position in which said shaft and said drive arm are displaced within said first displacement region by a shift of said food pedal from said first position to said second position through a rotation of said transmission means in a first direction, and a backward mode when said switch lever is in said reverse position in which said shaft and said drive arm are displaced within said second displacement region by a shift of said foot pedal from said first position to said second position through a rotation of said transmission means in a direction opposite to said first direction, and when said switch lever is in one said forward drive position said shaft and drive arm are displaced to a corresponding position within said first displacement region.

Abstract
A running control system for a vehicle having a stepless transmission includes a displaceable drive arm connected to the stepless transmission, a control member such as a pedal shiftable within a predetermined range, a transmission mechanism for transmitting a shift of the control member to the drive arm, and a forward-backward selecting lever switchable between a forward mode and a backward mode. The drive arm has a forward range to one side of a neutral position, and a backward range to the other side of the neutral position. When the selecting lever is switched to the forward mode, the drive arm is displaced within the forward range by the shift of the control member within the predetermined range. When the selecting lever is set to the backward mode, the drive arm is displaced within the backward range by the shift of the control member within the predetermined range.
