Abstract

BACKGROUND OF THE INVENTION The invention relates to bicycle building for amateurs and can be used in the design of a front-wheel drive muscular vehicle on controlled wheels and with a manual drive to the rear wheels. The purpose of the invention is to expand the functionality. On the axis of the crank shaft 1 with pedals, having the possibility of lateral movement when controlling the front wheels of the vehicle, one end of a telescopic type element 3 is pivotally mounted, the other end of which is also attached by means of a hinge to the middle part of the pillar the possibility of longitudinal and transverse movements, and the lower end of the rack is mounted on a universal joint containing a bearing 8, to which is attached the end of the rod, the drive shaft 10 and the axis on which The bearing is seated. This axis is rigidly attached to the drive shaft 10. A lever is also rigidly attached to the drive shaft, the free end of which is pivotally connected to the tongue 14, which is kinematically connected to the rear wheel bush. 4 il. (L

The invention relates to bicycle building for amateurs, in particular when designing a muscular vehicle (hereinafter referred to as MTS) with front-wheel drive on controlled wheels.

The aim of the invention is to expand the functionality.

FIG. 1 is given the muscular drive of the vehicle, top view; .cha fig. 2 - muscle drive of the vehicle, side view; in fig. 3 - the scheme of the universal joint; in fig. 4 - the same side view.

The drive consists of a crank shaft 1 containing pedals 2, a telescopic element 3 with variable length, one end of which is connected via a hinge 4 to the harmful part of the axis of the crank shaft 1, and the other end is connected to the middle part of the stand 6 by means of a ball joint 5 the end of which is rigidly fixed to the steering wheel 7, and the lower end of the post b is mounted on a cardan joint, including bearings 8, an axis 9 and a driving shaft 10, which is perpendicular to the axis of which is perpendicular to the axis 9. The driving shaft 10 is mounted on a hinge 11 AME. In the device, the lower end of the post 6 is rigidly attached to the bearing race 8 with the possibility of lateral movement of the post b by the bearing 8 and longitudinal movement by the hinge 11. One end of the lever 12 and the other end are also rigidly attached to the drive shaft 10. which, by means of a hinge 13, is connected to a cone of a connecting rod 14, the other end of which by means of a hinge 15 is attached to the eccentric axis of a driven sprocket 16 connected to an overrunning clutch 19, which is mounted on the hub of the rear drive wheel 20.

Muscular drive works as follows.

When the vehicle is moving forward due to the rotation of the pedals 2, the crank of the pogo shaft 1 controls the front wheels by means of the steering wheel 7 by moving it in the direction of rotation of the vehicle. In this case, the steering wheel 7 can be both distant from the driver, and close to it due to the free variation of the element length.

In the case of a manual drive, the driver produces a cyclic longitudinal swing of the steering wheel 7, enticing a stand 6, which cyclically reduces and lengthens element 3 through uiapHHp 5 and simultaneously through the cardan joint and lever 2 longitudinally moves the connecting rod 14 connected to it through 15 The rotational mass of the sprockets, the chain drive and the most closed chain rotates the eccentric axis of the driven sprocket 16 and, accordingly, the chain drive together with the overrunning clutch 19 and the rear wheel in the direction of the vehicle movement. By rotating the longitudinal action on the steering wheel 7, the overrunning clutch provides for the separation of the steering control from the manual drive. The lateral rigidity of the element 3 and the hinge 4 mounted on the axis of the crank shaft i and supporting the lower end of the pillar 6 through the cardan joint to the frame is controlled by lateral movement of the wheel 7 towards the desired rotation.

Claims (1)

Invention Formula A vehicle powered by human muscular power, containing front-wheel steering and a manual drive with a stand with a steering wheel at the upper end, and a lower end of the rack are kinematically connected with a lever connected to a connecting rod mounted on a driven sprocket, which is a chain drive, is associated with a rear wheel drive sprocket, and one of the elements of the steering drive is kinematically connected with a rack, characterized in that, in order to expand its functionality, the drive is In the form of a crank shaft with pedals, kinematically connected with one of the wheels, the steering element is pivotally mounted on the axis of the crank shaft with a telescopic steering element at one end, the other end of which is pivotally fixed to the middle of the rack the hinge is mounted on a drive shaft, which is hingedly mounted on a frame to which a lever is rigidly attached, while the steering wheel is mounted with the possibility of longitudinal and transverse movements. 75 5 FIG 2 / 2 FIG.
