Embodiment Construction

[0018] The following description is merely exemplary in nature and is not intended to limit the invention and its uses.

[0019] figure 1 A transmission assembly 10 is shown designed in accordance with the principles of the present invention. The transmission assembly 10 is described as a rear wheel drive transmission, however, various other types of transmissions may be used. The transmission assembly 10 generally includes a gear assembly 12 , a stationary member 14 , an outer brake 16 and an input shaft 18 . The input shaft 18 is driven by an engine (not shown). Other components typically found in transmission assemblies, such as torque converters or output shafts, may also be included without departing from the scope of the present invention.

[0020] The gear assembly 12 includes a clutch housing 20 disposed around and enclosing the gear arrangement 22 . The clutch housing 20 is typically secured to an external support, such as the frame of a motor vehicle (not shown)....

Abstract

A transmission assembly includes a clutch housing, a gear arrangement disposed within the clutch housing, and a fixed component. A brake having a housing and a hub is also included. The housing is coupled to the fixed component and the hub is coupled to the gear arrangement. The brake is disposed external to the clutch housing and cooperates with the gear arrangement to provide at least one forward or reverse gear ratio.

Description

technical field [0001] The present invention relates to transmissions, and more particularly to a transmission assembly having a torque transmitting device. Background technique [0002] The statements in this section merely provide background information related to the invention and do not necessarily constitute prior art. [0003] Transmission assemblies typically include multiple torque transmitting devices coupled with multiple gear sets. These torque transmitting devices cooperate with the gear sets to provide multiple forward and reverse gear ratios. A specific gear ratio may be selected by actuating a specific combination of torque transmitting devices. [0004] It is well known in the art that the number of ratios of existing gear assemblies can be increased by adding torque transmitting means. However, adding a torque transmitting device to an existing transmission can be difficult without modifying the housing and surrounding structure of the transmission. This...
