Transmission device for front wheel drive motorcycle - with power transmitted to front as well as rear wheel, to give improved grip and cornering

摘要

Movement is transmitted from point (1) at the output from the gearbox. The movement required for traction is transmitted to a free wheel (2) connected to a shaft (3) which transfers the rotation to a pinion (8) at one end. The movement reaches a special pinion (9) which drives a transverse shaft (10) which transmits the rotation to a pinion (11) at one of its ends. From this point, it drives the front wheel by a large chain held in position by three small pulleys (17,18,22) attached to compasses. A toothed wheel (25) prevents the wheel from locking. ADVANTAGE - Provides improved adherence and precision on heavy, sandy and rough ground and during high speed cornering.
