Bicycle with front hand drive

FIELD: transport engineering; bicycles.

SUBSTANCE: invention relates to hand drive of bicycle combined with its handlebar. With handlebar 1 being rocked reciprocation of carriages 4 is provided through connecting rods 3. Said carriages convey said motion to flexible members 5. Flexible transmission contains pulleys or sprockets 6 on axle 7 and sprockets 8 with overrunning clutches transmitting rotation of shaft 10 of front wheel.

EFFECT: improved utilization of rider's weight for driving.

The invention relates to a manual actuator bike by swinging the steering wheel.

In DE 2913912 A1 disclosed a Bicycle with a front hand drive, which is applied to the transducer of oscillatory movement of the steering wheel in a unidirectional rotating by installing fixed in the fork of the wheel bracket with a longitudinally oscillating the wheel in the form of two shoulders of the lever with transmitting the reciprocating motion of the carriage mounted on the flexible elements with the pulleys or sprockets, articulated planted on the axis, and sprockets, containing overrunning clutch on the axle of the front wheel. The disadvantage of this device is not using to drive the mass of the load.

In DE 383627 AND opened the connecting rod associated with the transverse wheel and crank mechanism. The disadvantage of this device is the low efficiency of complex machine-user.

The objective of the invention is the use of a force applied to the steering wheel when the support arms, to drive the front wheels, as well as in the distribution and simultaneous application of two vectors of forces to the supports with the two sides of the longitudinal axis of the Bicycle, for example, to the left leg and right arm, fully using to drive the mass of the load and eliminating virlanie machine that increases the efficiency of complex machine-user and unattainable in the analogue, for which applied: control the swing of the rudder against the sustained fashion to the longitudinal axis of the Bicycle, the connecting rod driving the flexible transmission, and adjust the length of the lever arm moves the end of the connecting rod on the handlebars. Moreover, to improve the reliability are two of the connecting rod and the carriage, the place of connection of the rod with flexible transmission is equipped with guides, opposing lateral displacement of the flexible element.

Thus, the set of essential features of the bike with the front hand drive is the use of the Converter oscillatory movement of the steering wheel in a unidirectional rotating by installing fixed in the fork of the wheel bracket with the wheel in the form of two shoulders of the lever. Transfer the reciprocating motion of the carriage mounted on the flexible elements with the pulleys or sprockets, articulated planted on the axis, and sprockets, containing overrunning clutch on the axle of the front wheel, is provided by the fact that the flexible drive elements through the carriage performed by the rods from the cross-section located steering wheel.

The drawing gives the scheme of the bike with the front hand drive.

The implementation of the invention is justified the application of the elements of the long-established industry, as well as tests of the experimental sample.

Device description in statics.

The bike (see the drawing) with the applied Converter oscillatory movement in a unidirectional rotational consists of ru is I 1 in the form of two shoulders of the lever with the bracket 2, fixed fork In the front wheel, connecting rod 3, a carriage 4 that are installed on the sites of a single flexible element 5 with the pulleys (asterisks) 6, the hinge planted on the axis 7, and sprockets 8, containing the overrunning clutch 9, still sitting on the axis 10 of the front wheel, and guides for the carriages 11, and the connecting rods 3 articulated planted on crosses 12 with the tabs 13 and the stopper 14 locks the steering wheel in the neutral position.

Description of the Converter dynamics.

Oscillatory movement of the steering wheel 1 on the bracket 2 results in reciprocating movement of the connecting rod 3, through which the carriage 4 transmits this movement to the flexible element 5 of the Converter with the pulleys (asterisks) 6, the rotating shaft 7, and the stars 8 with overrunning clutches 9, transmitting the rotation of the shaft 10 and wheel, while the carriage 4 moves along the guide 11, excluding the deflection of the flexible element, and, in addition, you can move the carriage by a flexible element, providing a height adjustment, and the rod shaft 12 and clamp 13 allow you to change the length of the shoulder L that facilitates the movement over rough terrain, and the stopper 14 locks the steering wheel in the neutral position and helps to learn the techniques of driving.

The bike with the front hand drive, which is applied to the transducer of oscillatory movement of the steering wheel in donapaula the TES rotational by installing fixed in the fork of the wheel bracket with the wheel in the form of two shoulders of the lever to provide a reciprocating motion to the carriage, mounted on the flexible elements with the pulleys or sprockets, articulated planted on the axis, and sprockets, containing overrunning clutch on the axle of the front wheel, wherein the flexible drive elements through the carriage is provided with rods from the cross-section located steering wheel.

Velomobile // 2249528

FIELD: transport engineering.

SUBSTANCE: invention relates to hand-and foot-operated drive which serves simultaneously as steering gear. Levers 7 between feet of driver are made sectional with possibility of removal of upper part when driver gets to place. Connecting rods 8 to drive wheels 3 are hinge-mounted on levers 7 and brackets 10 with pedals 11 are rigidly secured on levers. One of levers 7, being steering one, is connected with steering wheel 2 by tie-rod 16. Bushing 14 located higher than steering lever step bearing 13 provides free rotation of steering lever around its axle. Connecting rod 8 is hinge-mounted on bushing 14, and bracket 10 with pedal 11 is rigidly secured. Foot steps 18 in front part of velomobile can be lowered to thrust against ground when driver gets on seat to improved stability of velomobile.

EFFECT: possibility of using muscular force of hands and feet and using velomobile as training device.
