Abstract
A traction wheel has a pair of axially spaced apart annular rims presenting ground engagement surfaces which are inclined radially and axially inwardly toward one another to form the ground into a mound on which the wheel rides. A series of wedge-shaped lugs span the rims in circumferentially spaced apart relation. One of the inclined sides of several of the lugs extends radially inwardly to serve as a spoke for the rim. Each lug is generally V-shaped with an apex directed radially outwardly. An opening is formed through the apex both to increase traction and to dissipate any vacuum between the lug and ground.
Claims15
A traction wheel adapted to be mounted on an axle assembly, said traction wheel comprising,
- a pair of axially spaced apart annular rims, said rims presenting ground engagement surfaces which are inclined radially and axially inwardly toward one another,
- a plurality of generally edge shaped lugs connected to and extending between said pair of rims in circumferentially spaced apart relation, thereby to form openings through said wheel between said rims and adjacent pairs of lugs,
- each lug including leading and trailing sides with respect to the direction of rotation of said wheel,
- one side of a first plurality of is lugs extending generally radially inwardly of said rims to serve as a spoke thereof,
- hub means connected to said one sides of said first plurality of lugs, said hub means including means for mounting said wheel on an axle assembly,
- each lug being generally V-shaped with an apex directed radially outwardly, and
- at least one lug having an opening through the apex thereof.
