Claims34
A vehicle comprising a frame, wheels and a noncontact gripping force driving mechanism, said noncontact gripping force driving mechanism comprises an engaging means which enabling slow wheel to be engaged to drive and fast wheel to be disengaged to free run,
- said engaging means comprising a hub body, a driving drum, poles of noncontact force, a driving shaft and a shift screw, said poles of noncontact force being embedded inside said driving drum and said frame, said shift screws being on said driving shaft, said engaging drum being rotationally mounted on said shift screw, said poles of noncontact force being coupled between said driving drum and said frame to provide gripping force to said driving drum,
- said driving shaft being supported on a truck with bearings being mounted on the driving shaft, said hub body being mounted on said bearings,
- a rotational motion of said driving shaft being transferred from said shaft to said hub body through the incorporation of said hub body and said driving drum,
- as said shaft being rotated in one direction, said drum being pushed toward a wall of said hub body to engage said hub body, said hub body being rotated together with said shaft,
- as said shaft slowing down, said hub body disengaging with said drum and becoming free running,
- as said shaft being rotated in a reverse direction, said drum being pushed toward another wall of said hub body to engage said hub body, said hub body being rotated in a reverse direction.
A vehicle comprising a frame, wheels and upper bounded lateral gripping force driving mechanisms, said upper bounded lateral gripping force driving mechanism comprises an engaging means which enabling slow wheel to be engaged to drive and fast wheel to be disengaged to free run,
- said engaging means comprising a hub body, an driving drum, grippers, gripping spring, a driving shaft and a shift screw, one of said gripper having a protrudes to fit in a knotch on said driving drum, another of said gripper having a protrude to fit in a knotch on said frame, said gripping spring being inserted between said two grippers, said shift screws being on said driving shaft, said engaging drum being rotationally mounted on said shift screw, said gripping spring expanding to push said grippers against said driving drum and said hub to provide gripping force to said driving drum,
- said driving shaft being supported on a truck with bearings being mounted on the driving shaft, said hub body being mounted on said bearings,
- a rotational motion of said driving shaft being transferred from said shaft to said hub body through the incorporation of said hub body and said driving drum,
- as said shaft being rotated in one direction, said drum being pushed toward a wall of said hub body to engage said hub body, said hub body being rotated together with said shaft,
- as said shaft slowing down, said hub body disengaging with said drum and becoming free running,
- as said shaft being rotated in a reverse direction, said drum being pushed toward another wall of said hub body to engage said hub body, said hub body being rotated in a reverse direction.
A vehicle comprising a frame, wheels and differential driving mechanism, said differential driving mechanism comprises a nondivided and continuous axle and engaging means which enabling slow wheel to be engaged to drive and fast wheel to be disengaged to free run, at least two of said wheels being rotationally mounted on said nondivided continuous axle to drive said vehicle;
- said engaging means comprising a hub body, an driving drum, a nondivided continuous driving shaft and shift screws, said shift screws being on said driving shaft, said engaging drum being rotationally mounted on said shift screw, said gripping force being coupled between said driving drum and said frame to provide gripping force to said driving drum,
- said driving shaft being supported on a truck with bearings being mounted on the driving shaft, said hub body being mounted on said bearings,
- a rotational motion of said driving shaft being transferred from said shaft to said hub body through the incorporation of said hub body and said driving drum,
- as said shaft being rotated in one direction, said drum being pushed toward a wall of said hub body to engage said hub body, said hub body being rotated together with said shaft,
- as said shaft slowing down, said hub body disengaging with said drum and becoming free running,
- as said shaft being rotated in a reverse direction, said drum being pushed toward another wall of said hub body to engage said hub body, said hub body being rotated in a reverse direction.
A vehicle comprising a differential height mechanism, said differential height mechanism comprising a handlebar means, steering shock absorbing mechanisms and twin wheels,
- a frame being supported by said steering shock absorbing mechanism and having a bracket pivotally holding a steering post of said handlebar means,
- said steering shock absorbing mechanism having a fork structure comprising two single arms, each single arm comprising an steering shock tube only, said steering shock tube comprising an upper portion and a lower portion, said upper portion and said lower portion only slidably fitting into each other, each of said lower portion having a horizontal axle at one end, a wheel of said twin wheel being rotationally mounted on each of said axle, said arms adjusting its length respectively to keep the wheels lying on ground during steering, said steering shock absorbing mechanism tilting and being able to recover to a natural straight forward position after steering.
