Embodiment Construction

[0107] will be described together below Figure 1a ) to 1d) show the inventive electric drive assembly 2 . The electric drive assembly 2 may be used in a multi-axle, correspondingly all-wheel drive motor vehicle (not shown here) comprising a rear axle driven by an internal combustion engine as the primary drive, and a front axle which may optionally be driven . The rear axle is driven by a rear propeller shaft drivingly connected to a multi-speed transmission of the motor vehicle. The front axle is driven by a forward propulsion shaft, which is drivingly connected to the electric drive assembly 2 . The electric drive assembly 2 forming the auxiliary drive can be fixed to the multi-speed transmission of the motor vehicle, more specifically to the rear part of the multi-speed transmission.

[0108] The electric drive assembly 2 comprises an electric motor 6 , a reduction gear 7 , a coupling 8 optionally externally controllable with an actuator, and a transmission shaft 9 . O...

Abstract

The invention elates to an electric drive assembly for a multi-axle driven motor vehicle which comprises an internal combustion engine, a multi-step transmission with an output shaft for driving a rear axle, as well as an optionally drivable front axle. The drive assembly comprises an electric machine (6), a reduction gearing (7) drivingly connected to the electric machine (6), a driveshaft (9) drivingly connected to the reduction gearing (7) and drivingly connectable to a front propeller shaft (65) for driving the front axle, and a housing 5 in which the electric machine (6) and the reduction gearing (7) are arranged. The housing (5) comprises connecting means (16) for connecting the drive assembly (2) to the multi-step transmission. The electric drive assembly is designed such that, with the electric drive assembly mounted at the multi-step transmission (56), a rear propeller shaft (57) can be connected at least indirectly to the output shaft of the multi-step transmission for driving the rear axle. Furthermore, the invention relates to a motor vehicle with such a driveline assembly.

Description

technical field [0001] The invention relates to an electric drive assembly for a multi-axle drive motor vehicle comprising two drive sources, and to a motor vehicle having such an electric drive assembly. A drive concept with two drive sources is also referred to as a hybrid drive, and a motor vehicle equipped in this way is also referred to as a hybrid vehicle. An internal combustion engine is generally set as a first drive source, and an electric motor is set as a second drive source. The internal combustion engine and the electric machine can each be combined to drive the motor vehicle by themselves or when superimposed on each other. Background technique [0002] The advantage of a hybrid drive is that the internal combustion engine can be operated more frequently in the favorable efficiency range for a longer period of time. When the vehicle accelerates, the internal combustion engine and electric motor can operate in conjunction. During braking and cruising of the v...
