Combined transmission // 2628554
FIELD: transportation.SUBSTANCE: transmission comprises a drive pulley rigidly fixed to the input shaft, a driven pulley fixed to the output shaft and a gear train comprising a drive gear rigidly fixed to the input shaft in engagement with the driven gear wheel rotatably fixed to the output shaft. The transmission additionally contains an override clutch fixed to the output shaft, on which the driven pulley is mounted. The belt drive is located outside the casing.EFFECT: increased transmission reliability and durability while reducing the risk of injury.5 cl, 5 dwg

Bicycle sixteen speed transmission // 2613392
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.2 dwg

Chassis wheel // 2551579
FIELD: transport.SUBSTANCE: chassis wheel comprises rim on shaft and multiple grousers on rim periphery. Wheel rim part is not integral with the hub and is asymmetric therewith but runs in step therewith. Air tube of atmospheric pressure is fitted on said rim. The latter is shaped to cylindrical drum with flanges provided with through holes made in generatrix for grousers. Besides, said holes are formed in tire drum rim. Wheel rim part drive is composed of three spinning rollers, top one being intended for inner engagement with said flange and two bottom rollers arranged in symmetry with top one are intended for external engagement.EFFECT: improved cross-country capacity.2 dwg

Pedal drive // 2493999
FIELD: transport.SUBSTANCE: invention relates to device to drive transport facilities by human muscles. Proposed drive has two stages, one being composed of two planetary mechanisms with carries 2, 3 rigidly coupled with carriage shaft 1 and composed of a plate integrated with carriage shaft 1 to double as a flywheel with plane pinions 4, 5 fitted on extending ends and engaged with sun gears 7, 8 at gear ratio of unity. Said sun gears are fitted concentrically with carriage shaft on both sides and fixed to vehicle body 9. Pedals 10, 11 are fitted on radial permanently horizontal levers 12, 13 directed forward. Axial ends of horizontal levers 12, 13 are rigidly connected with plane pinions 4, 5. Second stage is composed of gearing with gear 16 fixed at carrier rim 2 while gear 17 is fitted on drive axle 18 of one of vehicle actuators.EFFECT: higher traction and efficiency.1 dwg

Rack-type race bicycle // 2477240
FIELD: transport.SUBSTANCE: invention relates to bicycle with reciprocating pedals. Pedal 23 is fitted on pusher 21 provided with gear 20. Spring-loaded rack 16 has teeth on its both sides to engage with overrunning coupling 13, 14 and gear 20. Extra rack 22 is a stationary element. Gear 20 interacts with stationary rack teeth and those of spring-loaded rack 16. In pedal downward travel, spring-loaded rack stroke is doubled due to addition of two motions. Pusher translation with gear 20 and rotation driven by engagement od gear 20 with fixed rack 22.EFFECT: increased speed.3 cl, 4 dwg

Bicycle // 2463194
FIELD: transport.SUBSTANCE: invention relates to bicycle with pedal drive incorporating reciprocating levers. On drive wheel axle (22), outer part of telescopic lever is installed. Gear (23) is installed on outer part of telescopic lever. Arc-shaped pinion rack (24) is mounted on bicycle frame. Gear (25) is linked with one-way rotation clutch (27). Gear (23) is engaged with arc-shaped pinion rack (24) and with gear (25).EFFECT: elimination of chain gear.2 cl, 6 dwg
