Problems solved by technology

Another problem with this design is that it is difficult to change the gear ratio because there is not enough room on the linear swing arm for the sheave to move along so that its free movement is not restricted by the presence of the frame and especially the chainstay

Embodiment Construction

[0031] figure 1 and 2 A perspective view showing a detail of a bicycle with a drive device according to the invention using a swing arm from a different perspective. In addition to the drive system used, the bicycle is also equipped with conventional parts or units, including a rigid frame 1 made of tubular elements, with corresponding front and rear wheel holding forks, and in the rear fork The end area is provided with a corresponding groove or socket for mounting the end of the axle 3 of the rear wheel 2 . The front fork and front wheel are not shown in the figure because the front wheel is not driven.

[0032]The frame 1 has frame rods which extend and branch from below approximately in a V-shape towards the handlebar and the saddle respectively, and these rods are connected to each other at their lower ends, and a lower hollow connection is provided in this connection region element, which has a different design compared to a similar connection area on a conventional ...

Abstract

Alternating drive primarily for bicycles and similar driven vehicles, in which the rotation of driven pedals are converted into reciprocating swinging motion of swinging arms, and the swinging arms have respective driving arms (16, 16') coupled to a head portion (14, 14') surrounding the swinging shaft (11) of the pedals from which a traction arm (17, 17') is extending out that closes an angle with the driving arm and the remote ends of the driving and traction arms (16, 17) are interconnected by a connection arm (20, 20').; A substantially triangular opening is formed between these arms, and the shaft of a driving wheel (15, 15') is positioned in this opening, the traction arm defines a traction path (19, 19'), and a flexible pulling rope (28) that rotates the driven wheel of the vehicle is led around at least one rope wheel (26) that has a shaft (35) guided and led along the traction path for adjusting the transmission ratio.

Description

technical field [0001] The present invention relates to an alternate drive, primarily for bicycles and similar driven vehicles, wherein said vehicle comprises a frame and driven wheels pivotally connected to the frame, said drive comprising a pair of identically designed , drive units with opposite driving directions and installed on the corresponding sides of the vehicle frame, each of the drive units includes a corresponding swing arm, and the swing arm pivots around a common swing axis mounted on the vehicle frame to perform rotation around the swing axis Alternating swinging motion, each swing arm having a corresponding drive arm having an edge defining a drive path, the unit comprising a motor mounted on the frame and pivoting on the frame to move about the drive axis common drive shaft for circular motion, each drive unit comprising a respective bolt and drive wheel, said bolt having an axis substantially parallel to said drive axis, and connected to said common drive sh...
