Abstract

A vehicle track system and assembly for outfitting vehicles for mobility in off-road conditions. Snow, mud, muck, soil, sand, ice, and other fickle conditions are more readily traversed. In an implementation, a spindle, a first driver, a drive sleeve, a second driver, and a single track are all part of the vehicle track assembly. Multiple of these components of the vehicle track assembly are furnished with one or more clocking indicia. The clocking indicia serves to provide rotational alignment indications amid assemblage procedures of the components of the vehicle track assembly. Proper timing of the drivers with respect to each other and attendant engagement with the single track is hence facilitated. Binding or other shortcomings observed with improperly-timed drivers is more readily resolved.

Claims17

a first driver connected to said spindle and driven to rotate by said spindle;
a drive sleeve having a second set of splines, said drive sleeve driven to rotate by said spindle via assembled engagement between said first set of splines and said second set of splines, said drive sleeve having a second clocking indicia;
a second driver connected to said drive sleeve and driven to rotate by said drive sleeve;
and
a single track driven to move by said first driver and by said second driver via engagement therebetween;
wherein said first clocking indicia and said second clocking indicia possess a rotationally-aligned arrangement with respect to each other, the rotationally-aligned arrangement between said first clocking indicia and said second clocking indicia providing concurrent and corresponding driving engagement between said first driver and said single track and said second driver and said single track with respect to each other;
wherein said first driver has a third clocking indicia and said second driver has a fourth clocking indicia, wherein said first, second, third, and fourth clocking indicia possess a rotationally-aligned arrangement with respect to one another, the rotationally-aligned arrangement among said first, second, third, and fourth clocking indicia providing concurrent and corresponding driving engagement between said first driver and said single track and said second driver and said single track with respect to each other;
and wherein said second driver comprises a second driver hub and a second driver trackring, said fourth clocking indicia located at said second driver hub or at said second driver trackring or at both said second driver hub and second driver trackring.
