Abstract
A motorized wheel assembly adaptable to skateboards provides drive motor and power sources and controls for the directed control of forward or backward propulsion of the skateboard using throttle and braking controls, the motorized wheel, and all skateboard wheels. Weight transfer assemblies for the motorized wheel transfer a portion of a skateboard rider's weight through the front mounted motorized wheel to the ground surface creating sufficient traction for the motorized wheel to propel the skateboard. One weight transfer assembly embodiment provides a pivoting, compression based mounting bracket. Separate embodiments of the weight transfer assemblies include single or dual shock absorbers.
Claims19
A combination of a skateboard having a deck and front and rear wheels and a motorized wheel assembly, the motorized wheel assembly comprising:
- a) at least one wheel comprising an axle;
- b) a wheel fork assembly connected to the axle;
- c) a drive motor assembly connected to the at least one wheel;
- d) a power supply connected to a throttle control assembly comprising a motor controller element and a throttle grip handle, the throttle control assembly also connected to the drive motor assembly;
- e) a braking assembly connected to the at least one wheel;
- f) a brake control assembly connected to the braking assembly;
- and
- g) a weight transfer assembly comprising in combination:
- i) a first attachment assembly communicating with the wheel fork assembly, and comprising a head tube assembly and a handle bar assembly;
- ii) a second attachment assembly communicating with a skateboard deck front end;
- iii) an element connecting the first attachment assembly communicating with the wheel fork assembly and the second attachment assembly communicating with the skateboard deck front end;
- and
- iv) an elastic, resilient element communicating with the element connecting the first attachment assembly communicating with the wheel fork assembly and the second attachment assembly communicating with the skateboard deck front end, the elastic, resilient element providing a range of motion between a first position in which the front skateboard wheels are above a planar surface below the skateboard upon connecting the motorized wheel assembly to a skateboard deck front end and a second position in which the front skateboard wheels contact the planar surface below the skateboard upon a skateboard rider stepping onto the skateboard deck, providing traction for the motorized wheel with the planar surface and allowing the skateboard rider to control forward or backward propulsion of the skateboard using the throttle control assembly, the braking control assembly, the motorized wheel assembly, and all skateboard wheels, and the elastic, resilient element providing the force to return to the first position after the rider steps off the skateboard deck.
A combination of a skateboard having a deck and front and rear wheels and a motorized wheel assembly, the motorized wheel assembly comprising at least one wheel comprising an axle, a wheel fork assembly connected to the axle, a first attachment assembly communicating with the wheel fork assembly, a second attachment assembly communicating with the skateboard deck, and an elastic, resilient element communicating with the first attachment assembly and the second attachment, providing a weight transfer assembly a) to elevate the front skateboard wheels off of a planar surface below the front skateboard wheels until a skateboard rider steps onto the skateboard deck at which time the rider's weight lowers the front skateboard wheels to the planar surface, b) to provide traction for the motorized wheel assembly with the planar surface, and c) to allow the skateboard rider to control forward or backward propulsion of the skateboard using the motorized wheel assembly.
