Background art.

In the patent № RU 2426021 C1 from 10.08.2011 described cable drive in which torque from a main Cam on a driven eccentric is transmitted by a cable attached to the line passing through the axis of the driving and driven eccentrics. In some traditional designs of mechanisms, such as the use of a cable drive instead of a chain, on bicycles and motorcycles on the line between the wheel axle and the axle of the drive sprocket are design elements that may prevent the displacement of ropes. Cycling on a line between the axes of the leading and driven sprockets is the bracket of the rear wheels, and motorcycle axle rear suspension arm of the wheel.

Disclosure of the invention

The invention is aimed at giving additional possibilities of application the control cable in machinery, in which between the axes of the driving and driven shafts are structural members that may interfere with the displacement of ropes.

A prototype device was taken the construction described in patent No. EN 2426021 C1 from 10.08.2011. For obstacle avoidance, which is located on the line passing through the axis of the driving and driven shafts, it is proposed that the ends of each rod-rope splicing, having an annular rope,�EP ring which should allow you to install it without a gap on the diameters of the driving and driven eccentrics. Since the rotation is transmitted by the movement of the eccentrics, the fastening of the cables from turning on the periphery of the eccentrics is not required, it is enough to limit the movement of the cable-connecting rod along the axis (from saskachewan with eccentrics). These annular connecting rods-cables to put on the master and slave Cams all set. Outwardly, it will appear as widely used in engineering belt and gear transmission, with the difference that for the transmission connecting rods-cables should be not less than three annular rod-rope, as shown in Fig. 1 and 2.

In these drawings one unit more than the other eccentrics, at the same eccentricity, to increase the space needed to bypass the obstacles that are placed on the line connecting the axis of the driven and driving shafts.

If you need to increase the uniformity of the flow of torque to the driven shaft are mounted sets of eccentrics from four to twelve units, as proposed in the prototype.

Brief description of the drawings

Drive cable, which cables cranks are a closed ring shown in Fig. 1 and Fig. 2, where POS. 1 - a ring rope that passes around the outer eccentrics, POS. 2 - ring rope passing around medium eccentrics, POS. 3 - ring rope passing around the inner eccentrics, POS. 4 - �camping swing hanging at the back of the wheel.

Variant implementation of the invention.

Setting ring control cable on a motorcycle will allow you to bypass the axis of the suspension arm of the rear wheel, allowing the traditional design of the rear suspension is unchanged.

Fig. 3 and Fig. 4 shows the installation of dual-control cable on a motorcycle in the embodiment, when the use of closed ring ropes on the leading and trailing excentrico equal diameter, where POS. 5 - axle rear suspension arm of the wheel.

1. Apparatus for transmitting torque, containing a set of at least three leading eccentrics and the set of slave eccentrics and connecting rods-cables, characterized in that every match in the master and slave Cams are connected to the annular connecting rods-cables, which are installed on the diameters of the leading and trailing eccentrics.

2. A device for transmitting torque according to claim 1, characterized in that to increase the space for structural elements that are installed on the line between the axes of the driving and driven shafts, the diameters of the eccentric drive shaft or driven shaft can be increased in size at the same eccentricity.
