    摘要： A continuously variable transmission pedal control system includes a forward pedal connected to a forward pivoting bracket, a reverse pedal connected to a reverse pivoting bracket, a first spring connecting the forward pivoting bracket to a linkage such as a bell crank at a first attachment point, and a second spring connecting the reverse pivoting bracket to the linkage at a second attachment point. The linkage may be connected by a motion control rod to a continuously variable transmission that provides a variable forward traction drive speed based on a position of the forward pedal and a variable reverse traction drive speed based on a position of the reverse pedal.

    摘要： A system for a self-propelled vehicle with variable travel speed, such as a mowing tractor, includes, between the primary driving shaft of the vehicle and an output shaft, such as the wheel drive shaft of the vehicle, at least one controlled variable speed drive with a belt and controlled mechanism for reversing the direction of travel of the vehicle, the primary driving shaft transmitting, via the variable speed drive, its motion to the input shaft of the reversal mechanism, itself able to directly or indirectly engage the output shaft, such as the wheel drive shaft of the vehicle, in such a way as to allow the vehicle to travel forward or in reverse respectively, at a variable travel speed. This transmission system is characterized in that the variable speed drive and the mechanism for reversing the direction of travel of the vehicle are controlled selectively from the same control device.
