Three-wheel motorcycle

Abstract

A three-wheel motorcycle having an outer frame with rear wheels mounted on a double axle with differential therebetween for a drive from a powerful automobile type engine together with an inner support frame pivotally mounted from said main outer frame with said inner pivotal frame supporting the front motorcycle type single steerable wheel. Handlebars mounted for four-way movement together with an operator's seat and passenger seats are also supported and mounted on the pivotal frame. A unique hydraulic actuated tilting mechanism is associated with the two frames for semi-automatically tilting the inner pivotal frame and the front wheel, operator and passenger thereon, whenever the operator turns the handlebars in order to make a turn of the vehicle and/or a turn is made which will exert centrifugal force upon the device. A pivotally suspended mass associated with the actuating mechanism aforesaid will automatically through the hydraulic mechanism tilt the inner frame whenever centrifugal force acts upon said suspended mass. This automatic operation as effected by the pivoted mass will function as a safety factor to automatically tilt the inner frame even though the operator neglects to do so. Other features include a fail-safe system for the hydraulic mechanism in case of hydraulic failure, a unique shock and spring mechanism for the inner frame, and the use of the frame tubing as part of the overall cooling system for the high powered internal combustion engine.
