Trends in the Development of Automotive Automatic Transmissions. Designs. Operation
Abstract: In order to determine the trends in the development of automatic transmissions, the article examines some of the promising designs created recently, as well as the designs of their individual elements. As an example, the following are selected: an alternative transmission clutch, which functions by analogy with an overrunning clutch; a step-by-step automatic transmission without hydrodynamic transmission, in which the smooth connection of the internal combustion engine and transmission is carried out by friction discs; a gearbox in which a cone with teeth acts as the leading link – the solution allows you to switch gears without interrupting the power flow. The work also compares automatic transmissions produced since the first decade of the current century with those released in 2019–2020, according to a number of parameters: estimated life, mileage of the car before maintenance of the automatic transmission, range and number of gear ratios, oil used. Based on the results, the expected trends in the development of the considered units on cars are formulated.
Keywords: gearbox, transmission, trends, reliability, service life, layout gear ratio.
