Abstract
Wheels of a crawler-type vehicle have rims that are laterally movable relative to the axis in response to a force subjected on the rim. The rim is biased by resilient material to return to its normal position in response to removal of the force on the rim.
Claims7
A track wheel for a crawler-type tractor comprising:
- a hub;
- a rim spaced a preselected distance from the hub;
- first and second spaced apart panels for connecting the hub to the rim, said second panel being connected to the first panel and spaced from the hub;
- a holding element having first and second opposed sides and extending from the rim to a preselected location between the panels;
- first means for biasing the rim holding element in a first direction generally parallel to the axis of the hub in response to a force of a preselected magnitude being subjected onto the rim in a direction toward the hub while generally maintaining said rim said preselected distance from the hub at the location where the force is applied;
- and
- second means for biasing the rim holding element in a second direction, said second direction being opposed to said first direction and generally parallel to the axis of the hub, said second means being a preloaded deformable resilient elastomeric element.
