Abstract

Additional hydraulic drive with variable displacement is a closed-type / variable-speed hydrostatic transmission consisting of at least two hydraulic machines (12, 20, 27) integrated into the car structure and transmission and one differential assembly (8), where mentioned hydraulic machines coupled to pressure lines (17), furthermore, at least one of said machines (12, 20, 27) is designed as a variable displacement machine, and at least one of said hydraulic machines is provided with at least one clutch (21). Mentioned machines provide additional drive of the rear, normally non-driven wheels (10), of the front-wheel drive cars, at least one variable displacement hydraulic machine (12) is connected to the drive machine (2, 25) and forms the basis of the pump module (11) which, when accelerated and maintaining achieved speed, converts mechanical energy, in the form of input torque and speed, into the hydraulic energy in the form of pressure and flow, which, in the drive module (19), during acceleration and maintenance is converted back into the mechanical energy, further into the drive module (19), at least one hydraulic machine is integrated, which primarily serves as an motor (20, 27), and at least one clutch (21) which enables said motor (20, 27) to connect with rear wheels (10), when it is necessary to provide additional drive torque on said rear wheels (10), or disconnect when additional drive on rear wheels (10) is not required, and where said transmission ratio is primarily changed by changing displacement of at least of one variable displacement machine, as it is a closed-loop hydrostatic transmission, where, during braking, the pump (12) can function as a motor and the motor (20, 27) can function as a pump, further to distribute the torque, toward the right and left wheel (10) function of the differential assembly (8) integrated into said drive assembly (19) is used.
