Трансмиссия колесной машины

Abstract

Для автомобиля C-класса с передним приводом разработана гидромеханическая трансмиссия. Расчётная мощность двигателя составляет 110 кВт. Трансмиссия включает планетарную коробку передач, обеспечивающую пять передач вперёд и одну назад, а также комплексный гидротрансформатор, главную передачу, межколесный дифференциал. Коробка передач спроектирована для компоновки в одном картере с гидротрансформатором и главной передачей. Трансмиссия реализована гидравлическим управлением, предусмотрен блокиратор гидротрансформатора(блокировка). Также был выполнен проектировочный-тяговый рaсчёт трaнсмиcсии c целью определения передаточных отношений. На основе полученных передаточных отношений выполнен синтез схемы коробки передач с двумя степенями свободы, проведены кинематический и силовой расчёты. Количество передач было увеличено до пяти. Для выбранного автомобиля был выполнен поверочный тяговый расчёт, построены характеристики: тяговая и разгонная. Были рассчитаны на долговечность и прочность основные детали трансмиссии: зубчатые передачи, валы, подшипники и фрикционные элементы управления.

A hydromechanical transmission has been developed for a C-class car with front-wheel drive. The estimated engine power is 110 kW. The transmission includes a planetary gearbox providing five forward and one reverse gears, as well as an integrated torque converter, final drive, and cross-axle differential. The gearbox is designed to be assembled in one crankcase with a torque converter and final drive. The transmission is hydraulically controlled and has a torque converter lock (lock). A design and traction calculation of the transmission was also carried out in order to determine the gear ratios. Based on the obtained gear ratios, a synthesis of a gearbox diagram with two degrees of freedom was carried out, and kinematic and power calculations were carried out. The number of gears was increased to five. For the selected vehicle, a verification traction calculation was performed, and the characteristics were constructed: traction and acceleration. The main components of the transmission: gears, shafts, bearings and friction controls were designed for durability and strength.
