Abstract
A toy includes a vehicle body having a front portion and a rear portion. A pair of rear wheels is coupled with the rear portion and located on the vehicle so as to at least partially support the rear portion. A first electric motor is drivingly coupled with the at least one rear wheel. There is a pair of front wheels coupled with the front portion and located on the vehicle so as to at least partially support the front portion. The wheels have two sets of 3-dimensional spokes act as a level of shock absorbent freedom of rotation and a freedom of translation thereby to absorb kinetic energy from an impact force.
Claims20
A toy vehicle having a vehicle body with a front portion and a rear portion and a longitudinal axis extending through the front and rear portions;
- at least one rear wheel coupled with the rear portion and located on the vehicle so as to at least partially support the rear portion;
- at least one front wheel coupled with the front portion and located on the vehicle so as to at least partially support the front portion, wherein each of the at least one rear wheel and each of the at least one front wheel includes a flexible tire supported on a wheel hub assembly, the wheel hub assembly comprising:
- a first hub part and a second hub part coupled together,
- the first hub part having an outer rim concentrically spaced from a tubular wheel shaft by a first plurality of three-dimensional S shaped spokes spaced around and extending between the outer rim and the tubular wheel shaft;
- the second hub part having an inner rim concentrically spaced from a tubular driven shaft by a second plurality of three-dimensional S shaped spokes spaced around and extending between the inner rim and the concentrically spaced tubular driven shaft;
- wherein first and second pluralities of three-dimensional spokes act as a shock absorber, providing multiple degrees of freedom including a freedom of rotation and a freedom of translation thereby to absorb kinetic energy from an impact force.
A toy vehicle having a vehicle body with a front portion and a rear portion and a longitudinal axis extending through the front and rear portions;
- at least one rear wheel coupled with the rear portion and located on the vehicle so as to at least partially support the rear portion, at least one front wheel coupled with the front portion and located on the vehicle so as to at least partially support the front portion, wherein each of the at least one rear wheel and each of the at least one front wheel includes a flexible tire supported on a wheel hub assembly, the wheel hub assembly comprising:
- a first hub part and a second hub part axially coupled together,
- the first hub part having an outer rim concentrically spaced from a tubular wheel shaft by a first plurality of three-dimensional S shaped spokes spaced around and extending between the outer rim and the tubular wheel shaft;
- the second hub part having an inner rim concentrically spaced from a tubular driven shaft by a second plurality of three-dimensional S shaped spokes spaced around and extending between the inner rim and the concentrically spaced tubular driven shaft;
- wherein each of the first and second pluralities of three-dimensional spokes acts as a shock absorber, providing multiple degrees of freedom including a freedom of rotation and a freedom of translation thereby to absorb kinetic energy from an impact force.
