Abstract
A treaded traction device for model vehicles is provided. The treaded traction device includes a biasing assembly and a tensioning assembly. The biasing assembly includes a first bias support fixed relative to a vehicle hub and a second bias support fixed relative to a traction hub. The biasing assembly also includes a coil and a dampener attached to the first and second bias supports. The treaded traction device is biased to result in one end being lower than another end. The tensioning assembly includes an idler wheel and a first and second tension support. The tension supports may be rotated to move the idler wheel, releasing tension on a surrounding tread. When the tension is released, the surrounding tread may be removed or replaced.
Claims16
A model vehicle comprising a treaded traction device comprising:
- a drive wheel providing a motivating force to a surrounding tread;
- a biasing assembly comprising:
- a first bias support fixed relative to a vehicle hub;
- a second bias support fixed relative to a traction hub;
- a resilient member coupled to the first bias support and the second bias support;
- and
- a dampener member coupled to the first bias support and the second bias support;
- wherein the treaded traction device is biased such that a rear end of the treaded traction device is rotated about the drive wheel to be positioned lower than a front end of the treaded traction device when the treaded traction device is unloaded.
A treaded traction device for a model vehicle comprising:
- a tensioning assembly comprising:
- an idler wheel;
- a first tension support pivotally coupled with the idler wheel and pivotable between a first tensioned position and a first untensioned position;
- a second tension support pivotally coupled with the idler wheel and pivotally coupled with a treaded traction device structure supporting a drive wheel axle;
- a tension securing device for releaseably securing the first tension support in the first tensioned position;
- wherein the second tension support is pivotable between a second tensioned position and a second untensioned position;
- wherein the idler wheel is rotated away from an inner surface of a surrounding tread when the second tension support is pivoted between the second tensioned position to the second untensioned position facilitating removal of the surrounding tread.
A treaded traction device for a model vehicle comprising:
- a drive wheel providing a motivating force to a surrounding tread;
- a biasing assembly comprising:
- a first bias support fixed relative to a vehicle hub;
- a second bias support fixed relative to a traction hub;
- a coil coupled to the first bias support and the second bias support;
- and
- a dampener member coupled to the first bias support and the second bias support;
- wherein the treaded traction device is biased such that a front end of the treaded traction device is rotated about the drive wheel to be positioned higher than a rear end of the treaded traction device when unloaded.
