(57) Abstract:Usage: in an ecologically clean transport, sports, tourism. The essence of the invention: improved operational efficiency by improving efficiency when the seat is made in the form of a physical pendulum, kinematically coupled to musculature drive. 2 Il. The present invention relates to the field of transport engineering, in particular to velomobiles, is designed to convert the muscular energy in the torque of the drive wheel and can be used in biotransport media, special, such as a wheel, sport-tourism, mountain rescue, and other purposes.Known recumbent "Retrasar" containing the dump of the front and povorotnoye parts of the frame with a seat and a pedal-chain drive steering.The downside of it is operational lowefficiency caused by the presence of non-productive energy consumption associated with the necessity of raising the legs above the level of the center of gravity of the pilot.Also known biotransport device containing a frame with a seat and pedals the lowefficiency, due to the presence of modes of dead zones in the operation of the crank drive mechanism.The closest in technical essence to the present invention is biotransport tool containing a dump of the two parts of the frame and the seat, one of the links of which contains a telescopic tube and a front wheel with pedal-chain drive, and another link frame has a rear wheel mounted on the ends of the rotary axis, is made in the form of an arc, its middle part is fixed on the axis connecting the links of the articulated frame, with the pivot axis is inclined backward in the vertical plane that contains the elastic element and provided with stops.The lack of operational lowefficiency, due to wasteful energy consumption related to the presence of modes of dead zones in the operation of the crank mechanism pedal-chain drive.The purpose of the invention to improve efficiency by reducing wasteful power consumption by eliminating modes of the dead zones of the process chain drive.This goal is achieved in biotransport the tool containing the dump of the two parts of the frame with shiden the s is driven wheels with hinge and an elastic element, due to the fact that the seat is made in the form of a physical pendulum, and the seat is suspended within the second level of the frame on the elastic element and the hinge can be locked is connected with the drive circuit biotransport tools.The invention is the optimization of the conversion conditions muscular energy through bifactorial self-oscillations of the pendulum in the torque of the drive shaft.In Fig.1 shows the design biotransport means, implemented on the basis of, for example, drive-chain drive of Fig.2 is a top view.Biotransport tool contains the first link frame 1, the driven wheels 2, the foot rest 3, the latch 4, the drive circuit 5, the drive wheel 6, the second link frame 7, the hinge 8, seat 9, the elastic element 10, the suspension 11, a steering wheel 12 and the crotch strap 13.Works biotransport tool as follows.By opening, for example, type spring connection (not labeled) of the elastic element 10, the pilot takes a seat 9, is fastened by the belt 13, closes the carbine elastic element 10, captures the steering arms 12 and sets foot on the stop 3 of the first link of the frame 1 between the non-driven wheels 2.Sum of 5 and one of freewheel clutches (not labeled) on the master wheel 6 create torque, leading biotransport tool in motion.In the process of acceleration biotransport means physical pendulum formed by the seat 9 with the pilot and the elastic element 10 suspension 11, leaning back up and carries out the accumulation of energy.Upon reaching the pendulum to the extreme rear position, the pilot changes the appearance of the loading arms and legs with push-UPS on the tension. When this resultant force, forming torque is the sum of the efforts of the hands and feet, and the force of gravity acts through the above-mentioned kinematic chain, including the crotch strap 13 and the replacement of the first freewheel sprocket wheel 6 on the second.Upon reaching the pendulum extreme anterior position of the pilot again changes the appearance of the loading arms and legs with tension on wringing, and after the passage of the pendulum original state of the working cycle is repeated.Turn biotransport means carried out through the rotation of the second link frame 7 by modifying the existing efforts of the hands and feet, while the braking effect on the levers steering wheel 12. BIOTRANSPORT way with a seat mounted on the frame and connected with the drive circuit, Rulev the ryh seat, made in the form of a pendulum pivotally mounted on the elastic element can be locked.
FIELD: transport engineering; three-wheel tandem.
SUBSTANCE: invention relates to three-wheel tandem part of which is made in form of sedicar. Driven bicycle without front wheel is attached to side of driving bicycle. Reciprocating drive of driving bicycle in form of levers with drum is furnished additionally with shaft connected with axle of levers of driven bicycle to form common power system.
EFFECT: improved efficiency of tandem drive.
FIELD: transport engineering; folding tricycles with luggage carrier.
SUBSTANCE: proposed folding velomobile has T-shaped frame 1 on which seat 2 with backrest rake adjuster 3 and fore-and-aft adjuster to shaft seat along longitudinal axis of tubular frame and change distance between seat and pedals are secured. Brackets 4, 5 of seat 2 and luggage carrier 6 are installed on tubular frame 1 to which wheels 7, 8, 9 are connected being furnished with front mudguard 10 and rear mudguards 11, 12 on which reflectors 13, 14, 15 are installed. Front wheel 7 is secured by fork 16 and main steering column 17 which is connected with auxiliary steering column 18 and handlebar 19 by means of steering rods 20, 21. Foot drive 23 is coupled with right-hand rear wheel 8 through idler sprockets and chain drives. When necessary, transmission of torque to left-hand rear wheel can be provided.
EFFECT: increased efficiency of pedaling and reduced overall dimensions.
FIELD: transport engineering; sidecars.
SUBSTANCE: proposed folding sidecar contains bicycle 1 and sidecar 2 consisting of seat 3 with backrest rake adjuster 4, seat fastening brackets 5, 6, 7, 8 luggage carrier 9 installed on T-shaped tubular frame 10 on which wheel 11 and with mudguard 12 is fastened. Sidecar 2 is furnished with pedal drive 14. Tubular 10 consists of two interconnected parts and unit fastening sidecar 2 to bicycle 1. First part of frame includes tube with U-shaped bracket made to provide folding of frame 10. Second part of frame includes tubes 29, 30, 31 used to fasten wheel 11, and connecting tubes used to attach sidecar 2 to bicycle 1 by means of locks 35.
EFFECT: increased efficiency of pedaling and reduced overall dimensions.
SUBSTANCE: invention relates to bicycles with two front wheels. Extra front wheel 10 is fitted parallel with main front wheel 2, its diameter d making 0.7 to 0.9 of main front wheel diameter D. Extra front wheel axle is arranged below that of main front wheel 2 loaded by their dead weight. Distance L between main front wheel 2 and extra front wheel 10 makes main front wheel 0.1 to 0.2 of D. Both front wheels 2, 10 are equipped with spring dampers. In compliance with one version, wheels 2, 10 are arranged in symmetry on both sides of bicycle frame. In compliance with another version, main front wheel 2 is arranged in bicycle frame plane while that of additional front wheel 10 stays there aside.
