Hydromechanical transmission with hydrodynamic retarder vehicle of high power

摘要

The utility model relates to hydromechanical gears installed on vehicles with a capacity of 300 to 650 hp and can be used on heavy vehicles, high-traffic cars, city buses, road-building equipment, including those operated in mountainous areas and frequent stops with the function of the auxiliary brake system. A hydromechanical transmission of a high power vehicle is proposed, consisting of a hydraulic part including a torque converter (1), which consists of a pump (7), a turbine (8) and a reactor (9) wheels, where the reactor wheel (9) is equipped with a clutch (11) stroke, as well as the mechanism (10) of blocking the transformer, which consists of a booster (12), a piston (13), a thrust disk (14), friction steel (15) and metal-ceramic (16) disks and a hub (17) connected to a pump (5) and turbine (6) wheels, and the mechanical part, including One gearbox, made in the form of a planetary gearbox (2), and a gearbox, as well as control systems (3), power supply (4) and lubrication. The hydromechanical transmission further comprises a hydrodynamic retarder (45), kinematically connected with its mechanical part. Hydromechanical transmission provides increased efficiency and reduced dynamic loads on the transmission units, and also solves the problem of providing an effective auxiliary braking system.
