Abstract
In a moving vehicle such as an automobile, compressed air is used for powering the vehicle, for minimizing friction in the wheel bearings so as to maintain the vehicle's momentum and decrease the amount of energy required for maintaining the vehicle at a predetermined desired speed, and for braking the vehicle. The present invention can be used instead of a conventional internal combustion engine, or as an auxiliary means for decreasing the amount of energy that is consumed by an internal combustion engine to increase the speed of a vehicle and maintain a vehicle at a predetermined speed.
Claims12
A pneumatic drive assembly in which a drive wheel is adapted to engage a track, comprising:
- a frame,
- a drive wheel mounted to a drive shaft, said drive shaft being supported by said frame and movable relative to said frame,
- an enclosed chamber supported by said frame, said chamber defining first and second openings,
- a conduit communicating with said first opening in said chamber for providing air to said chamber,
- means for regulating the entry of air into said chamber, whereby an operator can have air admitted into said chamber or substantially prevent air from entering said chamber,
- a second conduit having one end in communication with said second opening in said chamber,
- pneumatic cylinder means in communication with the other end of said second conduit, said pneumatic cylinder being supported by said frame and movable between an unextended position and an extended position,
- means for operably connecting said pneumatic cylinder means to said drive shaft,
- whereby when air is admitted into said chamber, said air exits said chamber into said second conduit, moves said pneumatic cylinder means from said unextended position to said extended position, and thereby moves said drive shaft and drive wheel from a first position in which said drive wheel is spaced apart from said track to a second position in which said drive wheel engages said track.
A pneumatic drive assembly, comprising:
- a frame,
- a drive shaft supported by said frame,
- a drive wheel mounted on said drive shaft,
- an enclosed chamber supported by said frame and defining first, second and third openings,
- a first conduit communicating with said first opening in said chamber,
- means for providing air to said first conduit,
- means for regulating the entry of air into said chamber through said first conduit,
- a second conduit having one end in communication with said second opening in said chamber,
- a third conduit having one end in communication with said third opening in said chamber,
- first air motor means in communication with the other end of said second conduit, said first air motor means including first rotatable means operably connected to said drive shaft and adapted to rotate said drive shaft in a first direction,
- second air motor means in communication with the other end of said third conduit, said second air motor means including second rotatable means operably connected to said drive shaft and adapted to rotate said drive shaft in an opposite second direction,
- means for regulating the entry of air into said second conduit, and
- means for regulating the entry of air into said third conduit,
- whereby an operator can admit air into said chamber and admit air into said second conduit, said air actuating said first air motor means which thereby turns said first rotatable means and said drive shaft and rotates said drive wheel in a first direction, and can admit air into said third conduit for rotating said drive shaft and said drive wheel in an opposite second direction.
