Embodiment Construction

[0018] exist Figure 1 to Figure 3 different embodiments of an electrically driven axle with a dog shifting element for decoupling the electric drive EM and a parking mechanism for locking the driven drive of the vehicle are shown by way of example in locking device.

[0019] The electrically driven axle according to the invention comprises a parking lock and at least one electric drive EM with a drive gear of a drive shaft or a rotor 1 of a rotor shaft 2 , wherein the electric drive EM as an electric machine can be used both as an electric motor It can also be driven by a generator. The drive gear 1 is coupled with the driven gear 5 (for example, with two-stage spur gear teeth, etc.) via at least one intermediate gear 3 of the countershaft 4 or directly with the differential 6 to drive the first driven gear 1. Shaft 7 and a second output shaft 8 , which for example drive the rear wheels of the rear axle of the vehicle.

[0020] For decoupling the electric drive EM, the cla...

Abstract

The invention proposes an electric drive axle of a vehicle comprising a parking lock and comprising at least one electric drive (EM) with a drive wheel (1) of a drive shaft (2), wherein the drive wheel (1) is coupled to an output wheel (5) of a differential transmission (6) by means of at least one intermediate wheel (3) of an intermediate shaft (4) for the purpose of driving at least one output shaft (7, 8), wherein, for the purpose of decoupling the electric drive (EM), at least one dog-clutch shift element is associated with the drive shaft (2) and / or with the intermediate shaft (4) in such a way that the dog-clutch shift element is arranged upstream of the parking brake in the direction of flow of force starting from the electric drive (EM) to the differential transmission (6).

Description

technical field [0001] The invention relates to an electrically driven axle of a vehicle of the type defined in detail in the preamble of patent claim 1 , having a parking lock and at least one electric drive. Background technique [0002] For example, from document DE 10 2015 119 075 A1 an electronic drive module for a vehicle is known with an electric motor which is coupled to a differential assembly via a transmission gear set assigned to a layshaft in order to drive a driven axle of the vehicle. To decouple the electric motor from the differential assembly, the intermediate shaft of the transmission gear set is assigned a clutch mechanism. [0003] If the parking lock for locking the slave of the vehicle is assigned to this intermediate shaft when the vehicle is at a standstill, there is the problem that the parking lock with the clutch mechanism at the intermediate shaft disengaged Cannot lock the follower. Contents of the invention [0004] The basic object of the ...
