The invention relates to vehicles driven by human muscle force.Known vehicle driven by human muscle force /U.S. patent N 1653889, 1927/, containing a frame mounted on it the steering wheel from the steering fork, front and top rear wheels, a pair of actuating levers, each of which is a front end pivotally mounted on one side of the frame and supplying the priori pulley, then a flexible rod wound on one of the overrunning clutches, pair mounted on a drive axis, and then covering the intermediate roller is wound in the opposite direction to the second overrunning clutch, and covering the second support pulley, a flexible rod mounted on the second drive lever, suspending it.A disadvantage of the described vehicle is the placement of the axis of rotation of the intermediate roller perpendicular to the axis of rotation of the overrunning clutches, in which the movement of the flexible rod to the right or left excluded diameter of the roller, while at the overrunning couplings flexible rod has a lateral move in connection with the winding number of coils or unwinding them. All this creates significant friction flexible rod about its coils, it is possible leap through a series of turns thrust that creates the instability of the operation of the device, the loss of his power and rapid wear, and free location flexible rod on the overrunning clutch also contributes to its tangles and additional resistance to the unwinding or winding, which also reduces efficiency and makes its operation unstable.The present invention is the task of creating a vehicle driven exploitatie, would have high efficiency.This task is solved in that in the vehicle driven by human muscle force, containing a frame mounted on it the steering wheel from the steering fork, front and top rear wheels, a pair of actuating levers, each of which is a front end pivotally mounted on one side of the frame and provided with a platform for the feet, flexible rod, which is attached the ends to the drive levers, thus covering the supporting pulleys mounted on the frame, it is wound on the overrunning clutch, pair mounted on a drive axis, and overrunning clutch connected by means of a flexible rod, covering the intermediate roller mounted on a frame, according to the invention the axis of rotation of the intermediate roller are mounted parallel to the axis of rotation of the overrunning clutches, and the intermediate roller is made winding flexible rod, while the overrunning clutch is located in the sleeve, with cut-outs for the release of flexible rods, and the gap between the wound on overrunning coupling flexible shaft and the sleeve is less than the thickness of the flexible rod.Winding flexible rod at an intermediate roller setting it parallel to the axis of rotation of the overrunning helped to make the winding of the flexible rod at right angles STS due to the misalignment of the flexible rod, and also to exclude the quick wear of the flexible rod. Installing overrunning in the sleeve, with cut-outs for the output of the flexible rod, and with a gap between the wound flexible shaft on the overrunning clutch and the sleeve is less than the thickness of the flexible rod is possible to eliminate leap flexible rod through the coil wound on the overrunning clutch, thus preventing the jamming device or impulse flexible rod.Ultimately, the device is reliable in operation, durable, simplifies its manufacture and maintenance.The invention is further explained in the description of examples of implementation with reference to the accompanying drawings, in which:
Fig. 1 depicts a vehicle according to the invention, side view,
Fig. 2 - the same device according to the invention, the view from the top.The vehicle, driven by human muscle force, according to the invention includes a frame 1 /Fig. 1, 2/, mounted on it, the steering wheel 2 to the steering fork 3, a front wheel 4 and the rear wheels 5, a pair of actuating levers 6, each of which is supplied by the platform 7 feet with an attached flexible shaft 8. Flexible rod 8, to suspend one drive levers 6, covering potamology on the frame 1 intermediate roller 12 and connects the overrunning clutch 10, located in the sleeve 13, having openings for the release flexible rod.The proposed vehicle is used as follows.Standing with one foot on the platform 7 of one of the actuating levers 6 and the other pushing off from the ground, the driver presses on another platform 7, and the bending rod 8 attached to the drive lever 6 around the supporting pulley 9, causes the rotation of the attached overrunning clutch 10, with the drive axle 11 and rear wheels 5, while rotating, and an intermediate roller 12, which, due to the installation of it along the axis of rotation of the overrunning clutches, puts the coils of the flexible rod 8 is perpendicular to the axis of rotation, and a sleeve, which are the overrunning clutch 10, it is not possible to knot flexible traction 8 when winding through supporting the pulley 9 and the lifting of the first drive lever. When the compression on the first drive lever and the process repeats.It should be understood that the above-described exemplary embodiment of the vehicle shown in purely illustrated purposes only and does not limit the invention, which can be made various changes and modifications not departing from the limits of its volume, which is determined by the proposed formula. which means, known in the art.The proposed vehicle can be used in transportation, household, medical and sports equipment. 1.
