Abstract:
A twist vehicle, comprising:a vehicle frame; a rear operation system which comprises: a driving member rotatably supported by said vehicle frame; a driving belt pulley coaxially connected to said driving member such that when said driving member rotates, said driving belt pulley is driven to rotate accordingly; a driven member which is frontwardly apart from said driving member and rotatably supported by said vehicle frame; a driven belt pulley coaxially connected to said driven member such that when said driven belt pulley is driven to rotate, said driven member is also driven to rotate by said driven belt pulley; and an endless transmission member, which is retained in position by said driven belt pulley and said driving belt pulley, for mechanically connecting said driving member with said driven member, such that when said driving member rotates, said driving belt pulley is arranged to drive said endless transmission member, so as to drive said driven member to rotate accordingly; a twisting unit connected to said driven member of said rear operation system, such that when the driven member is driven to rotate, the twisting unit is then driven to rotate accordingly; a pair of driving wheels rotatably connected to said twisting unit in such a manner that said pair of wheels spaces apart from each other and said axle of said pair of driving wheels spaces apart from front portion of said twisting unit; and a steering unit connected to said driving member of said rear operation system, such that when said steering unit rotates, said driving member is driven to rotate accordingly; such that when clockwise and anticlockwise movements are subsequently imparted to said steering unit, said rear operation system is capable of transferring said clockwise and anti-clockwise movements to said twisting unit, causing said twisting unit to rotate accordingly, and therefore drives said twist vehicle to move forwardly.
