Transmission with torsional damper

摘要

The present teachings provide for a torsional damper and a transmission having a torsional damper. The torsional damper can include first and second members. The first member can include a first hub, a first outer portion, and a plurality of first spokes. The first hub can be non-rotatably coupled to an input member of the transmission. The first spokes can extend radially between the first hub and the first outer portion. The first spokes can couple the first outer portion to the first hub. The second member can include a second hub and a second outer portion. The second hub can be non-rotatably coupled to an output member of the transmission. The second outer portion can be radially outward of the second hub and can be fixedly coupled to the second hub and to the first outer portion.

主权项

1. A transmission comprising:
an input member, the input member having a hollow tubular shape; an output member, the output member having a hollow tubular shape; and a torsional damper including:
a first member including a first hub, a first outer portion, and a plurality of first spokes, the first hub being non-rotatably coupled to the input member for common rotation with the input member about an axis, the first outer portion being radially outward of the first hub, the first spokes extending radially between the first hub and the first outer portion, the first spokes coupling the first outer portion to the first hub; anda second member including a second hub and a second outer portion, the second hub being non-rotatably coupled to the output member for common rotation with the output member about the axis, the second outer portion being radially outward of the second hub and fixedly coupled to the second hub and to the first outer portion, the first and second hubs defining a central aperture; and a first shaft drivingly coupled to one of the input member or the output member to receive torque from the one of the input member or the output member, the first shaft being supported for rotation about the axis relative to the input member and the output member, and the first shaft being received concentrically within the input and output.
