Abstract
A full-locking differential drive mechanism, comprised of an input drive which is composed of a pair of opposed spaced drive races, each having an inner diameter, a coupling block disposed between the races for coupling them to drive together, output driven means comprising a pair of co-axially disposed coupler members, each having an outer diameter disposed within the drive races inner diameters, which produces a bi-directional roller clutch disposed between the inner diameters and the outer diameters and operative to couple the drive races to the coupler members enabling driving engagement therebetween.
Claims21
A full-locking differential drive mechanism, comprising:
- input drive means comprising a pair of opposed spaced drive races, each having an inner generally cylindrical bore with a plurality of recesses;
- a coupling block disposed between said races for coupling them to drive together;
- output driven means comprising a pair of co-axially disposed coupler members, each having an outer cylindrical surface disposed within said drive races inner diameters;
- and
- a plurality of transmitting elements, or rollers, disposed in said recesses between said inner generally cylindrical bore and said outer cylindrical surface defining a bi-directional over-running roller clutch, coupling said drive races to said coupler members.
A full-locking differential drive mechanism adapted to fit into a standard differential case, comprising:
- input drive means comprising a pair of opposed spaced drive races positioned on each side of a pinion shaft, each having a central bore;
- said central bore of each race formed with a plurality of symmetrical recesses;
- at least one drive slot in an opposed face of each of said drive races;
- a coupling block adapted to mount on said pinion shaft and engage said drive slots between said races for coupling said races to drive together;
- output driven means comprising a pair of co-axially disposed coupler members, each having an outer diameter disposed within said drive races central bores, and having an inner diameter for coupling to a drive shaft;
- and
- a plurality of free clutch rollers in said recesses defining a bi-directional clutch between said inner diameters and said outer diameters and operative to couple the drive races to the coupler members;
- and
- a control plate operatively connected to said drive block and having fingers extending between said rollers for controlling the engagement and disengagement of said clutch rollers.
A full-locking differential drive mechanism adapted to fit into a standard differential case, comprising:
- input drive means comprising a pair of opposed spaced drive races positioned on each side of a pinion shaft, each having a central bore;
- said central bore of each race formed with a plurality of synmmetrical recesses;
- at least one drive slot in an opposed face of each of said drive races;
- a coupling block adapted to mount on said pinion shaft and having a drive lug on each side thereof to engage said drive slots between said races for coupling said races to drive together;
- output driven means comprising a pair of co-axially disposed coupler members, each having an outer diameter disposed within said drive races central bores, and having an inner diameter for coupling to a drive shaft;
- a plurality of free clutch rollers in said recesses defining a bi-directional clutch between said inner diameters and said outer diameters and operative to couple the drive races to the coupler members;
- and
- a control plate operatively connected by a transfer lever to said drive block and having friction fingers engaging said inner bore, and control fingers extending between said rollers for controlling the engagement and disengagement of said clutch rollers.
