Embodiment Construction

[0012] The rear axle of the shown double-track vehicle is driven by means of an electric motor 1 or the two wheels of this axle can be driven by means of an electric motor 1 via an associated drive shaft 23 or 24, said wheels being braked in the drawing via corresponding brake discs. Indicates (brake disc 21 on the left side of the vehicle and brake disc 22 on the right side of the vehicle). The drive shafts 23 , 24 extend from the transmission 2 with integrated differential, which is functionally and spatially connected to the output pinion 1 a of the electric motor 1 arranged in the region of the rear axle. However, the drive motor can also be arranged differently.

[0013] The two wheels, that is to say the wheel carrier 25 of the wheel on which the respective brake disc 21 or 22 is mounted rotatably about its axis of rotation as usual, are each guided by a total of five wheel guide rods 3 , 4, 5, 6, 7 are guided, and said guide rod is articulated with its end facing away ...

Abstract

The invention relates to an electrically driven axle of a dual track vehicle having drive shafts allocated to the wheels and an axle support having a plurality of wheel-guiding drivers fastened thereto, wherein at least one electrical motor or an axle drive is fastened to the axle support and furthermore a housing comprising elements for providing electrical energy for the electrical motor or for an electrical drive motor connected to the drive shafts via the axle drive is fastened to the axle support or forms a component of the axle support in the form of a main body. The housing is designed in a stepped manner in the side view and consists of an upper shell and a lower shell, the coupling joint of which extends upwardly toward the rear of the vehicle. According to the invention there are also front and rear continuous cross-members, having bearings for linking the axle to the vehicle body in the two end regions thereof. Wheel-guiding drivers are fastened via bearing brackets on the housing and / or on one of the cross-members and / or on a molded part flanged laterally to the housing. Furthermore, according to the invention, a fuel tank installed in the vehicle for supplying an optionally provided internal combustion engine can encompass the step level which is front-most in the driving direction formed by the housing.

Description

technical field [0001] The invention relates to an electrically driven axle of a double-track vehicle, comprising a drive shaft assigned to the wheels and an axle support having a plurality of guide rods fastened thereto guiding the wheels, at least an electric motor or an axle The transmission is fixed on the shaft support, and in addition the housing is fixed on the shaft support or forms an integral part of the shaft support in the form of a basic body, said housing contains the electric motor or the drive motor connected to the drive shaft through the shaft transmission. Components of electrical energy. Such an axle is shown in the non-pre-published German patent application DE 10 2010 043 901. Background technique [0002] It is well known that the supply of sufficient electrical energy for off-rail electric motor vehicles presents a major challenge with regard to the required installation space, since the energy storage density of batteries is considerably lower than ...
