The vehicle, driven by human muscle force
(57) Abstract:Use of invention: in the velomobile with chain drive between the disks of the front wheel, relates to the field of transport engineering, in particular wielostronne. Summary of the invention in that, without increasing the overall dimensions, increase speed, to facilitate a move to reduce the effect of lateral torque on the steering wheel, to reduce aerodynamic resistance and prolong the life of the tricycle, in addition, Dobby node is set in the center of the sleeve lead of the front wheel, allowing to use a wheel with a larger diameter rim, and as a consequence to increase the speed and ease stroke tricycle, without increasing the dimensions of the prototype. By replacing the wheels with spokes on the disk is significantly reduced aerodynamic drag and increases the life, because the whole drive is protected from moisture and dust disks. 6 Il. The invention relates to the field of transport industry, in particular holoscreen.Known vehicle driven by human muscle force, containing a frame installed on the seat with backrest, wheels, wheel, pedalcycle front wheel, and sprocket unit with switch, kinematically connected with a driven sprocket mounted on the shaft of the wheel.The objective of the invention is that, without increasing the overall dimensions, to increase the speed when the lightness, to reduce the effect of lateral torque on the steering wheel, as well as to reduce aerodynamic drag.The task is achieved by the fact that the chain drive is "hidden" inside the disk of the wheel, reduce the drag and improve operational conditions, as the sprocket and chain are not exposed to dust and moisture.Thus, the prototype disadvantages mentioned above are eliminated, and the recumbent acquires a number of new qualities while maintaining the overall dimensions.In Fig. 1 shows the proposed vehicle side view, and Fig.2 is a General view of Fig.3 cross-section of the drive wheel; Fig. 4 a longitudinal section of the drive wheel; Fig.5 foot node and the hub of the drive wheel; Fig.6, the intermediate sleeve with a power driven sprocket.The drive consists of a drive wheel with disk 1, pedal, consisting of axis 2, connecting rods 3, 4 pedals, tube 5, a stationary bushing 6, cones 7, Central time is it driven by the sprocket wheel 13 drives fastened together by bolts 14 and spacers 15, one of which on the balls setting unit of the slave sprocket 16, 17, 18, 19, one of which is connected by a chain with a sprocket wheel 13.The drive works as follows.The rotation of the pedals is driven axle 2 with the shifter 20, sitting on the key 21. Gear shifting is performed by the foot pressing on the connecting rod 3 to the left or right. The position of the switch 20 is fixed ball stopper 22 in the annular recesses of the tube 5, having a longitudinal slot in which slides freely key 21.The rotation axis through the switch 20, which is engaged with one of the leading asterisks 9, 10, 11, is transmitted by the chain to one of the driven sprockets 16, 17, 18 and then through the sprocket 19 of the chain on the sprocket 13 and the overrunning clutch 12 on the drive sprocket. Turns are made by the wheel 23. There is a chair with a back. Braking using the normal tick brakes. The vehicle, driven by human muscle force, containing a frame installed on the seat with backrest, wheels, wheel and pedal actuator located on the front wheel and chain transmission, Dobby hub mounted on the shaft re is th on the shaft of the wheel, wherein the wheels are made of the disk, between discs wheel to its shaft has a sprocket unit with switch, its kinematic relationship driven sprocket is made by means of additional sprocket unit is installed on the spacer, the crimping wheels, while the switch is set to the key that is installed in the longitudinal slot of the shaft of the wheel.
FIELD: transport engineering; freight tricycles.
SUBSTANCE: invention relates to folding freight cycles designed for riding at reclining and with drive to front wheel. Transmission of proposed cycle consists of two strands of chain and/or belt drives interconnected by propeller shaft 16 or flexible shaft. Center 17 of cross of propeller shaft 16 is located on turning axle of front wheel fork 3 which is made in form of turned-over Y letter. Carrying frame consists of beam 1 and container interconnected by detachable joint. Cover of container is made in form of folding chair. Chain of first strand of drive is placed inside box beam 1. Second strand of drive is installed on fork 3 and it engages drive sprocket 12 in aperture 24 of vertical section of fork 3.
EFFECT: reduced overall dimensions of transmission and load on fork.

FIELD: transport engineering.
SUBSTANCE: invention relates to folding tricycles designed for riding in reclined position. Folding frame consists of two parts connected by hinge joint 3. One part of frame is telescopic. Cross beam 45 connected with hinged frame by attachment axle through connecting bracket can be turned in horizontal plane relative to attachment axle when folding the velomobile. Rear driving wheel 19 is arranged behind hinge-secured seat backrest resting on two stops fastened in rear part of frame. Two front wheels are turned on cross beam by means of handlebar, steering tie-rods and rocker and they are locked from turning when velomobile is folded. They are installed so that their lower edge is arranged at a smaller distance from horizontal axis of hinged frame than distance from horizontal axis of hinged frame to lower edge of driving wheel installed square to wheels on cross beam. Length of folded telescopic frame is 1.2 of diameter of driving wheel, that of rear part 4 of frame, is equal to (0.5+2a) of diameter of driving wheel, length of cross beam 45 with wheels 31 is equal to 1.44 of diameter of driving wheel, distance from hinge joint 3 to vertical axis of driving wheel 19 and from hinge joint 3 to vertical axis of attachment axle is (0.5+a) of diameter of driving wheel where a is width of driving wheel.
EFFECT: provision of stability of velomobile in folded state and possibility of movement of folded velomobile on its wheels as hand cart.
SUBSTANCE: invention refers to folding three-wheeler with electric motor. Folding accumulator vehicle contains two frames capable of movement one in another during folding and unfolding. Rear wheel contains electric motor attached to it. Seat is located over wheel. Fixing devices secure rigidity of vehicle in folded and unfolded condition. Front frame is supported by two wheels of bigger diameter and rear wheel is twice less in diameter than front wheels, but rear wheel is wider than front wheels. Front frame covered by net serves as a carrier, it contains shelf for basket with drop-side or for child's seat. Handlebars' post is inclinable to secure pull of brake cable and simultaneous switch-off of electric motor.
EFFECT: strengthening of protection from front side and acceleration of braking response.
SUBSTANCE: invention relates to scooter combined with skateboard. Step plate 26 can swing relative to lengthwise axis A extending from front to rear. Step plate 26 and front wheel are jointed together with respect to vertical axis with no articulation. Set step plate 26 has left and right parts located on left and right of front wheel to support user in upright position so that front wheel is located between user left and right feet. Steering 32 is arranged at front to extend upward. Pair of rear wheels is secured coaxially at rear to hunt relative to lengthwise axis between neutral position and hunting position 70. Scooter is controlled by hunting of rear wheels at asymmetric load of step plate left and right parts.
