Claims
- 1. An electric vehicle, comprising:
a vehicle frame; a driven wheel assembly comprising at least a driven wheel rotatably supported by said vehicle frame; and a power generator device supported by said vehicle frame comprising a clutch means for selectively engaging with said driven wheel assembly to drive said driven wheel rotate and disengaging with said driven wheel assembly such that said driven wheel is in a free rotating manner; and an electric-free driving system, comprising:
a transmission unit having an upper control portion positioned above said vehicle frame and a lower connecting portion extended underneath said vehicle frame; a steering means affixed to said control portion of said transmission unit for driving said connecting portion thereof to rotate in clockwise and anti-clockwise directions; a twister member having a driven portion connected to said connecting portion of said transmission unit; and a pair of driving wheels spacedly and rotatably mounted to said twister member wherein said two driving wheels are spaced apart from said driven portion of said twister member.
- 2. An electric vehicle, as recited in claim 1, wherein said transmission unit is a shaft rotatably penetrated through said vehicle frame and having a top end which is said control portion of said transmission unit connected to said steering means and a bottom end which is said connecting portion of said transmission unit connected to said twister member.
- 3. An electric vehicle, as recited in claim 1, wherein said power generator device further comprises an electric motor supported by said vehicle frame for driving an output axle to rotate and a power source connecting to said electric motor, wherein said clutch means is operatively connected to said output axle of said electric motor to selectively engage and disengage with said driven wheel assembly.
- 4. An electric vehicle, as recited in claim 3, wherein said driven wheel assembly comprises two driven wheels spacedly and rotatably mounted on a rear portion of said vehicle frame and a wheel axle having two end portion for rotatably supporting said two driven wheels on said vehicle frame respectively, wherein said clutch means is selectively engaged and disengaged with said wheel axle.
- 5. An electric vehicle, as recited in claim 4, wherein said clutch means comprises a first gear member coaxially connected to said output axle of said electric motor and a second gear member coaxially connected to said wheel axle, said clutch means being arranged to operate and maintain said first gear member between a powered driving position and an idle position, wherein in said powered driving position, said first gear member is engaged with said second gear member to drive said driven wheels to rotate through said wheel axle, and in said idle position, said first gear member is disengaged with said second gear member such that said driven wheels are in a free rotating manner.
- 6. An electric vehicle, as recited in claim 5, wherein said first gear member is detachably connected to said output axle of said electric motor in such a manner that said first gear member is adapted to attach to and detach from said output axle so as to engage and disengage with said second gear member, so as to selectively propel said electric vehicle by a power generator device and by manually respectively.
- 7. An electric vehicle, as recited in claim 2, wherein said power generator device further comprises an electric motor supported by said vehicle frame for driving an output axle to rotate and a power source connecting to said electric motor, wherein said clutch means is operatively connected to said output axle of said electric motor to selectively engage and disengage with said driven wheel assembly.
- 8. An electric vehicle, as recited in claim 7, wherein said driven wheel assembly comprises two driven wheels spacedly and rotatably mounted on a rear portion of said vehicle frame and a wheel axle having two end portion for rotatably supporting said two driven wheels on said vehicle frame respectively, wherein said clutch means is selectively engaged and disengaged with said wheel axle.
- 9. An electric vehicle, as recited in claim 8, wherein said clutch means comprises a first gear member coaxially and detachably connected to said output axle of said electric motor and a second gear member coaxially connected to said wheel axle, said clutch means being arranged to operate and maintain said first gear member between a powered driving position and an idle position, wherein in said powered driving position, said first gear member is engaged with said second gear member to drive said driven wheels to rotate through said wheel axle, and in said idle position, said first gear member is disengaged with said second gear member such that said driven wheels are in a free rotating manner.
- 10. An electric vehicle, as recited in claim 9, wherein said first gear member is detachably connected to said output axle of said electric motor in such a manner that said first gear member is adapted to attach to and detach from said output axle so as to engage and disengage with said second gear member, so as to selectively propel said electric vehicle by a power generator device and by manually respectively.
- 11. An electric vehicle, as recited in claim 3, wherein said driven wheel assembly is said electric-free driving system which is capable of selectively powering by said power generator device and operating by manually, such that said driven wheels of said driven wheel assembly are said two driving wheels of said electric-free driving system.
- 12. An electric vehicle, as recited in claim 6, wherein said driven wheel assembly is said electric-free driving system which is capable of selectively powering by said power generator device and operating by manually, such that said driven wheels of said driven wheel assembly are said two driving wheels of said electric-free driving system.
