Abstract

Example embodiments of the disclosed technology provide a clutch pack retention system. The system may comprise a backup plate assembly. The backup plate assembly may comprise a pair of plates that are coupled together. The pair of plates may comprise first and second plates. The first and second plates comprise teeth. The teeth of the first plate may be removably engageable with corresponding portions of a circumferential groove extending along an inner diameter of a drum of a clutch system. The teeth of the second plate may be removably engageable with corresponding grooves extending longitudinally into the drum of the clutch system. Coupling the first and second plates together may angularly offset teeth of the first plate relative to teeth of the second plate.

Claims20

Dependent claims

A backup plate assembly for a clutch of an automatic transmission, the assembly comprising:

a first plate comprising a first plurality of teeth spaced apart around an outer circumference of the first plate, the teeth of the first plurality of teeth removably insertable into corresponding portions of a circumferential groove which extends around an inner surface of a drum of the clutch;
and
a second plate couplable with the first plate, the second plate comprising a second plurality of teeth spaced apart around an outer circumference of the second plate, the teeth of the second plurality of teeth removably insertable in corresponding longitudinal grooves of the drum, the longitudinal grooves extending longitudinally inwards into the drum;
wherein the first plurality of teeth is angularly offsetable from the second plurality of teeth;
and
wherein coupling the first and second plates together preserves an angular offset between the first and second pluralities of teeth.
