MECHANISM FOR AUTOMATIC SELECTION AND GEAR SHIFTING IN MECHANICAL GEARBOX Russian patent published in 2020 - IPC B60K20/02 F16H61/28 

FIELD: control devices; machine building.

SUBSTANCE: invention relates to control devices of vehicle transmission. Mechanism for automatic selection and gear shifting in mechanical gearbox comprises housing (1) fixed on gearbox housing (2). In housing (1) there are gear selection rod (3) and gear shifting mechanism. On one end of gear selection rod (3) there is return spring (4), and on the other end of rod (3) there is gear selection device made in the form of cylinder (7), in which piston (8) and piston (9) are installed. Piston (8) is fixed on rod (3) rigidly, and piston (9) is installed with possibility of movement. Gearshift mechanism is composed of two-way piston (15) with cavities (16) and (17) for supply of working medium and return springs installed in housing (1). Gearshift mechanism is located perpendicular to selection rod (3) and is equipped with sensors (18). On rod (3) there is a movable switching lever (19) which interacts with double-sided piston (15) and is connected to rod (20) of gear shift located in gearbox housing (2).

EFFECT: technical result consists in increase in the number of gearshift stages and, as a result, in expansion of functional capabilities of mechanism of automatic selection and gear shifting in mechanical gearbox.
