GATE-LEVER RECTILINEAR-GUIDING MECHANISM OF INCREASED ACCURACY AND DRIVER FOR WHEELED VEHICLES DRIVEN BY MUSCULAR POWER OF A PERSON Russian patent published in 2018 - IPC B62M1/16 F16H21/04 

FIELD: machine building.

SUBSTANCE: group of inventions relates to machine building, in particular, to gate-lever mechanisms. Gate-lever rectilinear-guiding mechanism of increased accuracy consists of two fixed axes A and C, gate AB rotating around the first axis A, a lever BD forming a rotational pair and connected by means of a hinge B at one end to the gate AB. Hinge is rotatable about longitudinal movement in the die block and oscillating motion of the link AB, around the fixed axis A in the sector of 180 degrees. Length of the links of the mechanism satisfies the conditions AC/AB=1.73, BD/AB=7.46. Deviations of the trajectory of the point D of the lever BD from the straight line do not exceed 0.1 % of the length of the lever BD. Drive for wheeled vehicles contains levers with pedals, a free-wheel clutch, two rocker-link rectilinear guiding mechanisms. Gate-lever mechanisms are mounted on the frame of a vehicle and are rigidly connected to the semi-axis of the vehicle and through it with a freewheel and drive wheel.

EFFECT: expansion of the arsenal of drives of transport vehicles is achieved.
