FIELD: mechanical engineering.
SUBSTANCE: invention relates to bicycle gear box. Compact gearbox with small metal consumption is installed on the pedal assembly of the bicycle frame. The gearbox provides 16 speeds and consists of five pairs of gears, the two three-position switching clutches. Between the three rows of middle gears opposite deployed on-off clutches linked by joint switch plugs are mounted by two.
EFFECT: sixteen speed bicycle gearbox, expanding the operational and layout characteristics of the bike.
