Abstract
A continuously variable transmission for heavy duty vehicles, in which the classic hydraulic torque converter is permanently removed, comprising at least two planetary gear assemblies; a hydraulic pump, used as a gradual brake; a hydro-mechanical device for transforming the torque generated by the drive engine of the vehicle into a variable torque; a hydraulic regulator to control all torque variations in the hydro-mechanical device; a reverse drive mechanism that controls a forward or reverse movement of the vehicle; and a freewheel that allows for a transmission of a different variable gear ratios from the drive engine of the vehicle to at least one of the driving wheels or caterpillars.
Claims4
A continuously variable transmission for heavy duty vehicles, comprising:
- a main planetary gear assembly that is configured to provide a highest torque at the commencement of the movement of a vehicle or at any point in which said vehicle requires the higher torque;
- a hydro-mechanical device that is configured to work in conjunction to the main planetary gear assembly and that is configured to transform the torque generated by a drive engine of the vehicle into a continuously variable torque;
- a hydraulic regulator that is configured to adjust all torque variations taking place in the hydro-mechanical device;
- a freewheel that connects to a ring gear of the main planetary gear assembly that is configured to transmit different variable gear ratios to at least one of the driving wheels, or caterpillars;
- and
- a reverse shifter that is configured to control a forward or reverse movement of the vehicle.
