Gear driven by wobble movement and vehicle with this gear

Abstract

A gear driven by wobble movement contains an ergonomic pendulum (D), a centric disk (C) and a flywheel (A) having a common axis (S) of rotation. In the axis (S) of rotation a shaft (H) is placed which is joined to the pendulum (D). The mutual concentric position of the centric disk (C) and the flywheel (A) is delimitated by planet disk (B) which contacts the periphery of the centric disk (C) and the internal periphery of the flywheel (A) and is joined rotatably to the supporting structure (T). The supporting structure (T) is fixed to the linked structure which fixes the supporting structure (T), together with the planet disk (B), against rotation with respect to the axis (S) of rotation. A first freewheel (V1) is situated between the shaft (H) and flywheel (A) and a second freewheel (V2) is situated between the shaft (H) and centric disc (C).

Claims

1. A gear driven by wobble movement, said gear containing: a driving pendulum adapted to be driven by a person; a centric disk, wherein said driving pendulum and said centric disk have a common axis of rotation, wherein a shaft is located in the common axis of rotation; a flywheel positioned at said common axis of rotation, wherein the shaft is rigidly joined to the driving pendulum, wherein the mutual position of said centric disk and said flywheel is delimitated by a planet disk that contacts the outer periphery of said centric disk and the internal periphery of said flywheel, wherein said planet disk being rotatably joined to a supporting structure, wherein said supporting structure is fixed to a linked structure that connects said supporting structure with the planet disk against rotation with respect to said common axis of rotation; a first freewheel situated between said shaft and said flywheel; and a second freewheel situated between said shaft and said centric disk, wherein the senses of rotation of said first freewheel and said second freewheel are different, wherein the outer periphery of the flywheel is a wheel tread.

2. The gear driven by wobble movement according to claim 1, wherein the flywheel is adapted to mount a belt, a chain, or a toothed wheel.

3. A vehicle comprising the gear according to claim 1, wherein the linked structure has a form of a frame to which a wheel or a pair of wheels is fastened.

BEST MODE FOR CARRYING OUT THE INVENTION

(7) The gear driven by wobble movement contains the ergonomic pendulum D, the centric disk C and the flywheel A having the common axis S of rotation. The pendulum D is adapted to carry one person. In the axis S of rotation, the shaft H, joined rigidly to the pendulum D, is placed. The mutual concentric position of the centric disk C and the flywheel A is delimited by three planet disks B which contact the outer periphery of the centric disk C and the internal periphery of the flywheel A, said planet disks B being joined rotatably to the supporting structure T. The supporting structure T is fixed to the linked structure, said linked structure including this gear. The position of the supporting structure T is, together with the planet disks B, fixed against rotation with respect to the axis S of rotation.

(8) Between the shaft H and the flywheel A the first freewheel V1 is situated. Between the shaft H and the centric disk C the second freewheel V2 is located. The senses of rotation of the freewheels V1 and V2 are different.

(9) In this case the outer periphery of the flywheel A is a wheel tread. The linked structure to which the supporting structure T is fastened has the form of the frame U to which a pair of wheels K is fastened. The connection of the front wheel and the pair of wheels K contains the joint J which enables the vehicle to be steered directionally. If the vehicle has to be turned, the riding person transfers the centre of gravity to the needed side due to which the front wheel is inclined with the ergonomic pendulum D too. With the front wheel being inclined, the whole vehicle is turned thanks to the function of the joint J because the axes of the front wheel and of the rear pair of wheels K cease to be parallel. The joint J has a well-known structure and is utilized usually as a part of a steerable axle of a skateboard.

(10) An exemplary embodiment can be found on FIG. 1, FIG. 2, FIG. 3, and FIG. 5.

INDUSTRIAL APPLICABILITY

(12) The proposed gear will find its application in smaller transport means as bicycles, sledge or vessels especially. It can be utilized further e.g. for training device which is analogous to a pedalling training device or stepper or possibly to drive arbitrary smaller machines and devices.
