Abstract
A clutch assembly, constituting a component of a gear transmission, has two gear-carrying shaft extremities projecting from opposite sides of a clutch casing. One shaft extremity is provided with axially extending teeth, carried on its face or on a sleeve keyed thereto, normally engaging similar teeth on a confronting drive shaft. The other shaft extremity is mounted, by means of a combined journal and thrust bearing, in a retaining member which is detachably secured to the transmission housing and has passages for supplying pressure fluid (oil) to the clutch casing. Upon removal of the retaining member, the assembly can be axially shifted to disengage the first-mentioned shaft extremity from the drive shaft whereupon it can be laterally withdrawn from the transmission housing.
Claims10
A transmission system comprising:
- a housing;
- a drive shaft journaled in said housing;
- driven shaft means offset from said drive shaft and journaled in said housing;
- fluid-actuatable clutch means in said housing for optionally transmitting torque from said drive shaft to said driven shaft means, said clutch means being traversed by intermediate shaft means having two oppositely projecting extremities coaxial with said drive shaft;
- a first pair of gears idling on said extremities and meshing with a second pair of gears on said driven shaft means, said first pair of gears being couplable with said intermediate shaft means by actuation of said clutch means;
- a coupling between said drive shaft and one extremity of said intermediate shaft means, said coupling including interengaging axially extending formations on said drive shaft and said one extremity;
- a retaining member detachably secured to said housing;
- and bearing means axially and radially suporting the other extremity of said intermediate shaft means on said retaining member, said other extremity and said retaining member being provided with communicating passages for the selective admission of actuating fluid to said clutch means, said formations being disengageable by an axial shift of said clutch means relative to said housing after detachment of said retaining member to facilitate radial extraction of said clutch means jointly with said intermediate shaft means and said first pair of gears from said housing.
