Abstract

The invention discloses a driving assembly of a crow bar bending bicycle, a first crow bar and a second crow bar are arranged to be not on the same straight line so as to avoid parts on a rear wheel; a connecting piece on the pedal assembly is movably arranged in the sliding rail of the first crow bar, the second crow bar is rotatably hinged to the frame, when the pedal drives a rotating rod to rotate around a rotating shaft of the rotating rod by 360 degrees, the connecting piece rotates along with the rotating rod to drive the second crow bar to swing in a reciprocating mode along a hinged shaft of the second crow bar, and the rear wheel is driven through the curved bar on the second crow bar under the transmission effect of a flywheel driving mechanism. The torque is transmitted to the rear wheel through the crank lever by means of the flywheel crank mechanism, people do not need to relearn and adapt to the riding way, and the purposes of quicker speed and more labor saving can be achieved.

Description

technical field [0001] The invention relates to the technical field of bicycle driving mechanisms, in particular to a driving assembly of a crowbar cranking bicycle. Background technique [0002] Traditional bicycle is to connect pedal lever by pedal, and pedal lever connects big sprocket, and big sprocket is connected with the little flywheel on the rear wheel by chain, and little flywheel drives rear wheel to rotate, and bicycle can be walked. Since the bicycle is powered by the crank pedal, and is limited by the height of the bicycle frame and the range of motion of the human leg, the crank length of the bicycle is limited, and it is not labor-saving when riding. The only way to increase the pedaling frequency is to reduce The weight of the body is used to increase the speed, and it is easy to get tired during long-distance riding. [0003] In order to solve the above problems, some improvements to bicycles have been made on the market, making it more labor-saving when r...
