REVERSE GEARBOX Russian patent published in 2023 - IPC F16H37/02 F16H1/20 F16H7/00 

FIELD: mechanical engineering.

SUBSTANCE: reverse gearbox contains a housing, inside which is placed a single-stage gearbox, consisting of an input drive shaft and an output driven shaft. The drive shaft is configured to transmit torque from the engine to it. On the input drive shaft there is a drive sprocket installed freely, and a drive gear engaged with the drive shaft and configured to move in the longitudinal direction along the said shaft and block the drive sprocket. On the drive shaft, a driven sprocket is fixed, which is connected by a chain transmission to the drive sprocket, and a driven gear, made with the possibility of engagement with the drive gear. The reducer is also equipped with a gear lever cinematically connected to the drive gear and provides control of its longitudinal movement along the drive shaft, with the possibility of setting the drive gear to the locking position of the drive sprocket, setting the drive gear to the position of engagement with the driven gear or installing the drive gear gears to the neutral position without locking the drive sprocket or meshing with the driven gear.

EFFECT: increased reliability and manufacturability.
