MIRONOV AUTOMATIC STEPLESS TRANSMISSION

摘要

The invention relates to transport means, in particular to vehicles provided with a fluid power drive. The inventive transmission comprises a non-adjustable flat hydraulic pump which is cinematically connected to the engine of the transport vehicle and to at least one non-adjustable reversible flat hydraulic motor by means of pressure, discharge and suction hydraulic lines and through a hydraulic distributor which encompasses the pressure and discharge lines and operates in the form of a reverse in order to transmit torque to one or two drive wheels of said transport vehicle. The cavities of the suction and discharge lines are connected to a hydraulic tank cavity. The suction line passes through an adjustable hydraulic throttle which encompasses it and whose control lever is cinematically connected to the accelerator pedal of the transport vehicle. Said invention makes it possible to simplify the structural design of the transmission, reduce the fuel consumption, weight and the cost thereof and to increase the performance of the transport vehicle.
