Abstract
A drive assembly for a drive assembly or transmission is provided. The drive assembly includes a front cover; a piston plate slidable axially toward and away from the front cover; a connection plate axially between the front cover and the piston plate elastically connecting the front cover and piston plate to each other; and at least one seal along at least one radial end of the piston plate, the connection plate and the piston plate retaining the at least one seal axially therebetween. A method of forming a drive assembly is also provided.
Claims19
A drive assembly for a torque converter or transmission comprising:
- a front cover;
- a piston plate slidable axially toward and away from the front cover;
- a connection plate axially between the front cover and the piston plate elastically connecting the front cover and piston plate to each other, the connection plate being a single piece directly connected to the front cover by first fasteners and directly connected to the piston by second fasteners;
- and
- at least one seal along at least one radial end of the piston plate, the connection plate and the piston plate retaining the at least one seal axially therebetween,
- the connection plate including at least one leaf spring formed therein elastically connecting the front cover and the piston plate,
- at least one of the front cover and the piston plate being riveted to the at least one leaf spring, the at least one leaf spring including a free end and a base end, the free end and the base end being defined by spaces in an interior of the connection plate between an inner circumference and an outer circumference of the connection plate, the leaf spring including a radially outer edge extending circumferentially from the free end to the base end, the radially outer edge being radially offset from and radially inside of the outer circumference of the connecting plate.
A method of forming a drive assembly for a converter or transmission comprising:
- connecting a piston plate to a front cover through a connecting plate axially between the front cover and the piston plate such that the piston plate is slidable axially toward and away from the front cover, the connection plate being a single piece directly connected to the front cover by first fasteners and directly connected to the piston by second fasteners;
- and retaining at least one seal axially between the connection plate and the piston plate along at least one radial end of the piston plate, at least one of the front cover and the piston plate being riveted to at least one leaf spring, the at least one leaf spring including a free end and a base end, the free end and the base end being defined by spaces in an interior of the connection plate between an inner circumference and an outer circumference of the connection plate, the leaf spring including a radially outer edge extending circumferentially from the free end to the base end, the radially outer edge being radially offset from and radially inside of the outer circumference of the connecting plate.

- a connection plate axially between the front cover and the piston plate elastically connecting the front cover and piston plate to each other, the connection plate being a single piece directly connected to the front cover by first fasteners and directly connected to the piston by second fasteners;
- at least one seal along at least one radial end of the piston plate, the connection plate and the piston plate retaining the at least one seal axially therebetween;
- an outer radial support surface;
- an axially slidable clutch plate;
- and
- a clutch backing plate axially held at the outer radial support surface configured for limiting axial movement of the clutch plate, the at least one seal including a radial outer seal slidable along the outer radial support surface via movement of the piston plate, the piston plate and the connection plate being axially movable away from the front cover so the piston plate forces the clutch plate against the clutch backing plate.
