Розробка і впровадження комбінованої коробки передач та її застосування на легкових автомобілях

Abstract

A combined transmission of a car is designed, consisting of a mechanical part that will be used in all modes of movement of the car, and a variator (stepless), which is planned to be used only in traffic jams or at low speeds. A study of the use of mechanical gearboxes in traffic jams was also conducted. The input of the study determined: the total time spent in traffic, the distance traveled, the average speed of the car and how many times the driver switched the gear lever. The principle of operation of the designed transmission is described. A study on the temperature heating of the friction disk of the main clutch of the variator part of the designed gearbox. The study was conducted using SolidWorks in the software module COSMOSWorks Designer. As a result of the study, it follows that the thermal performance of the friction disc of the main clutch when applied to a third of the higher power compared to the nominal value allows without the risk of overheating and damage to use the designed transmission.
