Novel pedal driving device

The invention discloses a novel pedal driving device. The novel pedal driving device mainly comprises a frame (14), a gearbox (8) mounted at the back end of the frame (14), a driving rear wheel (10) mounted on a gearbox output shaft (27), an overrunning clutch (28) mounted on a gearbox input shaft (22) and pedal driving devices mounted on the frame (14) and the gearbox (8), and is characterized in that the pedal driving devices further comprise additionally arranged gear driving arms (6); and an independent pedal driving device driving system is provided, so that such defects as nonuniform stress, easy rupture and weak durability of the overrunning clutch caused by single-edge stress in the pulling of a drive connecting rod in the stepping of a pedal drive by users due to the use of the drive connecting rod of a bicycle with Chinese patent number of 201420590209.3 as a single-edge single structure in the prior art are solved, and such defects as labor waste in driving and possibility of touching the pedal driving arm to the driving rear wheel caused by direct installation of the back end of the pedal driving arm outside the gearbox are solved.
