Abstract
A belt drive system for a vehicle, such as a combine harvester. The belt drive system uses a driven pulley which is selectively engageable with a driven shaft to supply rotation to the shaft. The pulley is mounted on a fixed, i.e. non-rotating, housing using suitable bearings, such that the bearings of the pulley continue to rotate and are dynamically loaded for all rotation conditions of the driven pulley, i.e. whether the pulley is engaged with the shaft or not. This prevents damage to the bearings due to false brinelling.

A belt drive system for a vehicle, the belt drive system comprising:
- at least one driven pulley;
- an output shaft rotatable about an axis;
- a shift collar provided on said output shaft to selectively engage with said at least one driven pulley to drive said output shaft;
- a fixed housing, wherein the fixed housing comprises a first fixed end and a second free end, the first fixed end arranged to be secured to a fixed frame of a vehicle, wherein said shaft extends through the fixed housing and projects from said second free end of the fixed housing, and wherein said at least one driven pulley is rotatably provided on said fixed housing.
The belt drive system of claim 5, wherein the fixed housing comprises a flared section at said first fixed end, arranged to be mounted to a fixed frame.
The belt drive system of claim 5, wherein said at least one driven pulley is provided on said fixed housing at said second free end of said housing
