PULSE CVT FOR TORQUE TRANSMISSION

This paper presents a description of the design and operating principle of a pulse variator for transmitting torque. CVTs are used in mechanical engineering – in vehicle transmissions to transmit torque, slow down the speed of shaft rotation and in drives of a wide variety of technological equipment. The pulse variator contains: a fixed housing in which the drive gear, satellites, driven gear, carrier, drive gears, and drive shaft are installed. With the help of a differential type planetary mechanism, rotational motion and torque are transmitted from the drive gear to the driven gear by slowing down the speed of rotation of the carrier, using an impulse mechanism, which creates the braking torque necessary to transmit torque from the drive gear to the driven gear of the differential mechanism. By changing the angle of inclination of the washer and moving the slider along the spline shaft, the magnitude of the braking torque on the carrier and the rotation speed of the driven shaft are adjusted depending on the magnitude of the moment of resistance on the driven shaft. The advantage of the described variator design is the ability to regulate the speed of the driven gear depending on the magnitude of the moment of resistance on the gear, increasing the efficiency of the device, reducing heat losses, improving the reliability and durability of the device.
