Drifting kart
Drifting karts in accordance with embodiments of the invention are described that include a front wheel drive train and rear caster wheels that can be dynamically engaged to induce and control drift during a turn. One embodiment of the invention includes a chassis to which a steering column is mounted, where the steering column includes at least one front steerable wheel configured to be driven by an electric motor, a battery housing mounted to the chassis, where the battery housing contains a controller and at least one battery, wiring configured to provide power from the at least one battery to the electric motor, two caster wheels mounted to the chassis, where each caster wheel is configured to rotate around a rotational axis and swivel around a swivel axis, and a hand lever configured to dynamically engage the caster wheels to induce and control drift during a turn.
1. A drifting kart comprising:
a base;
a seat supported by the base;
a steerable front wheel;
a motor configured to drive the front wheel;
a plurality of rear caster wheels configured to rotate and swivel; and
a hand lever operably connected to the plurality of rear caster wheels, the hand lever having a first connection to the base and a second connection to the base, the second connection located forward of the first connection.
2. The drifting kart of claim 1 , wherein the first connection is located rearward of the seat.
3. The drifting kart of claim 2 , wherein the second connection is located adjacent the seat.
4. The drifting kart of claim 1 , wherein the first connection is located at a rear end of the drifting kart and the second connection is located at a middle of the drifting kart.
5. The drifting kart of claim 1 , wherein the hand lever comprises a grip and a mechanical linkage.
6. The drifting kart of claim 1 , wherein the hand lever is operably connected to the plurality of rear caster wheels such that movement of the hand lever alters the ability of the plurality of rear caster wheels to swivel.
7. The drifting kart of claim 1 , further comprising a battery located at a rear end of the drifting kart.
8. The drifting kart of claim 1 , further comprising a steering wheel.
9. The drifting kart of claim 8 , wherein the steering wheel is positioned above the motor and the motor is positioned above the front wheel.
10. The drifting kart of claim 8 , wherein an axis of rotation of the steering wheel is perpendicular to an axis of rotation of the front wheel.
11. The drifting kart of claim 8 , wherein the seat comprises a bottom and a backrest, the bottom located lower than the steering wheel.
12. A drifting kart comprising:
a base;
a seat supported by the base;
a steerable front wheel;
a plurality of rear caster wheels, each of which is configured to rotate around a respective rotational axis and swivel around a respective swivel axis; and
a hand lever operably connected to the plurality of rear caster wheels by a rotatable member, the hand lever comprising a first portion, a second portion, and a grip, the first portion extending upward, the second portion extending toward a front of the drifting kart, the first portion and the second portion connected by an articulating joint.
13. The drifting kart of claim 12 , wherein the grip is located on an end of the second portion.
14. The drifting kart of claim 12 , wherein the hand lever further comprises a third portion located forward of the first portion, the second portion and the third portion connected to the base by a movable joint.
15. The drifting kart of claim 12 , wherein the hand lever is configured to rotate the rotatable member from a first position to a second position, wherein in the first position the weight of the drifting kart limits the ability of the caster wheels to swivel about their swivel axes, and wherein in the second position the caster wheels are free to swivel about their swivel axes during motion of the drifting kart.
16. A drifting kart comprising:
a base;
a seat supported by the base;
a steerable front wheel on a front end of the drifting kart, the steerable front wheel located longitudinally in front of the seat and laterally between left and right sides of the seat;
a motor configured to drive the front wheel;
a plurality of rear wheels on a rear end of the drifting kart; and
a plurality of caster wheels located forward of the rear wheels.
17. The drifting kart of claim 16 , further comprising a steering wheel located above the front wheel and the motor.
18. The drifting kart of claim 16 , further comprising a hand lever, the drifting kart configured such that movement of the hand lever changes riding characteristics of the drifting kart.
19. The drifting kart of claim 18 , wherein the hand lever comprises a first connection to the base and a second connection to the base, the second connection located forward of the first connection.
20. The drifting kart of claim 18 , wherein the hand lever comprises a first portion, a second portion, and a grip, the first portion extending generally upward, the second portion extending toward a front of the drifting kart, the first portion and the second portion connected by an articulating joint.
21. A drifting kart comprising:
a base;
a seat supported by the base;
a steerable front wheel on a front end of the drifting kart;
a motor configured to drive the front wheel;
a plurality of rear wheels on a rear end of the drifting kart;
a plurality of caster wheels located forward of the rear wheels; and
a hand lever, the drifting kart configured such that movement of the hand lever changes riding characteristics of the drifting kart, wherein the hand lever comprises a first connection to the base and a second connection to the base, the second connection located forward of the first connection.
