Abstract
An improved hybrid transmission including two electric motor/generator modules and a plurality of planetary gear sets operatively connectable to the motor/generators and to an engine is provided. Novel structural and packaging schemes enhance the function and efficiency of the transmission. More precisely, the present invention relates to an improved apparatus for retaining a clutch hub and providing hydraulic fluid to actuate a clutch.
Claims14
A vehicle transmission comprising:
- a fluid source;
- a housing member defining a first flow passage in fluid communication with the fluid source;
- a center support disposed within the housing member, the center support defining a second flow passage in fluid communication with the first flow passage;
- a clutch hub attached to the center support;
- a clutch disposed within the clutch hub;
- and
- a plurality of fasteners adapted to attach the center support to the clutch hub, wherein at least one of the fasteners is a hollow fastener defining a third flow passage in fluid communication with both the second flow passage and the clutch such that the clutch may be actuated by fluid from the fluid source.
4 more elements
A vehicle transmission comprising:
- a fluid source;
- a pump in fluid communication with the fluid source and adapted to draw fluid therefrom;
- a valve body in fluid communication with the pump;
- a housing member defining a first flow passage in fluid communication with the valve body;
- a center support disposed within the housing member, the center support defining a second flow passage in fluid communication with the first flow passage;
- a clutch hub attached to the center support;
- a clutch disposed within the clutch hub;
- and
- a plurality of fasteners adapted to attach the center support to the clutch hub, wherein at least one of the fasteners is a hollow fastener defining a third flow passage in fluid communication with both the second flow passage and the clutch such that the clutch may be actuated by fluid from the fluid source.

A vehicle transmission comprising:
- a fluid source;
- a pump in fluid communication with the fluid source and adapted to draw fluid therefrom;
- a valve body in fluid communication with the pump;
- a housing member defining a first flow passage in fluid communication with the valve body;
- a center support disposed within the housing member, the center support defining a second and third flow passage in fluid communication with each other, the second flow passage being in fluid communication with the first flow passage;
- a clutch hub attached to the center support;
- a clutch disposed within the clutch hub;
- and
- a plurality of fasteners adapted to attach the center support to the clutch hub, wherein at least one of the fasteners is a hollow fastener defining a fourth flow passage in fluid communication with both the third flow passage and the clutch such that the clutch may be actuated by fluid from the fluid source.
