TRANSMISSION ASSEMBLY FOR VARIABLE SPEED AUTOMOTIVE ENGINE, ITS CONTROL DEVICE AND EQUIPMENT EQUIPPED WITH SUCH A TRANSMISSION ASSEMBLY

摘要

The invention relates to a transmission assembly for a self-propelled machine with variable forward speed, such as a mowing tractor, this assembly comprising, between the main shaft (1) of the engine and an output shaft (2), such as the drive shaft of the wheels of the machine, at least one controlled speed variator (3) belt (9) (15) and a mechanism (17) reversing direction of movement of the controlled machine ( 24), the primary motor shaft (1) transmitting, via the speed variator (3), its movement to the input shaft (11) of the inverter mechanism (17), itself able to come in engagement, direct or indirect, with the output shaft (2), such as the drive shaft of the wheels of the machine, so as to allow movement forward or backward respectively of the machine at a variable forward speed.This transmission assembly is characterized in that the variator (3) speed and the mechanism (17) inverter sense movement of the machine are selectively controlled from the same body (27, 35) control.
