Embodiment Construction

[0016] figure 1 The illustrated powertrain 10 includes an automatic mechanical transmission (AMT) 12 connected to a hydraulically assisted launch system (HLA system) 14 via an intermediate propshaft 16 . Another drive shaft, hereinafter referred to as drive shaft 18, is connected at one end to transmission 12 for connection at the other end to a (not shown) shaft. An adapter module 20 is incorporated into the transmission 12 to connect the HLA system 14 to the driveline. The adapter module 20 beneficially eliminates the need for a transfer case disposed between the transmission and the HLA system in prior art systems. The adapter module 20 provides most of the functionality of the transfer case with much less hardware. Master clutch 22 provides a selectively engageable drive connection between the vehicle's drive motor (not shown) and AMT 12 .

[0017] figure 2 schematically shows figure 1 A configuration of the drive train. The adapter module 20 is disposed between the...

Abstract

The present application relates to a drivetrain for a motor vehicle comprising an automated mechanical transmission (12) having an input shaft (28), an output shaft (30), a counter shaft (32) and at least two selectively engageable gear sets disposed between the countershaft and the output shaft. In order to assist in launching the vehicle, the application provides an alternative power source including a motor (50) and an energy storage unit (52, 54) and an adapter module (20) operable disposed between the automated mechanical transmission (12) and the motor (50). Said module (20) comprises an adapter gear set including a first gear (42) in mesh with a second gear (44), providing driving connections between the motor (50) and the transmission output shaft (30), a first clutch (46) selectively drivingly connecting the motor input shaft (38) to the countershaft (32) and a second clutch (44) selectively connecting the transmission output shaft (30) to the motor input shaft (38) through the adapter gear set (42, 44). The motor (50) may be hydraulic or electric.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 264987, filed November 30, 2009, which is hereby incorporated by reference in its entirety. Background technique [0003] Known hybrid vehicle drive systems that couple an internal combustion engine with an alternative power source, such as an electric motor or a hydraulic motor, require means to couple the alternative power source and the internal combustion engine to the drive wheels. Each configuration may have a preferred configuration, but these will vary with vehicle use and application. [0004] A common type of known electric hybrid system described in US Patent No. 7,463,962 has an electric motor coupled to the transmission input shaft. This configuration is well suited for use with transmissions having layshaft power flow configurations. However, by placing the electric motor in-line with the engine and transmission, the size of the elec...
