Problems solved by technology

[0004] The use of conventional brake systems in conventional vehicles with hybrid drives, usually hydraulic brake systems, which are complex and have a high installation space requirement and require frequent maintenance
Although the electric machine can also generate a certain braking effect in generator operation, this braking effect is not sufficient at higher speeds, so a conventional braking device must be additionally provided, which can be realized, for example, as hydraulic disc brake

Embodiment Construction

[0020] The motor vehicle 1 is symmetrically constructed and has at its ends each a wheel 2 which can be driven by means of an electric motor 3 . A control device (controller) 4 is provided for controlling and regulating the electric motor 3 , which is connected on the one hand to the electric motor 3 and on the other hand to the electrical connection 5 . The electric machine 3 has a cooling connection 6 which is connected via a heat exchanger to a schematically indicated heat store 7 , so that the electric machine 3 can be cooled while the heat store 7 is heated. The heat accumulator 7 can be used to regulate the temperature of the interior of the hybrid vehicle.

[0021] A transmission 8 is arranged between the wheels 2 and the electric machine 3 , by means of which the rotational speed of the electric machine 3 can be increased and the torque reduced. The transmission 8 is designed in such a way that the electric machine 3 runs in an optimum rotational speed range.

Abstract

The invention relates to a driven vehicle axle, which is coupled or can be coupled to an internal combustion engine and / or at least one electric machine that optionally can be operated as an engine or generator and which comprises a brake device having an eddy current brake (10).

Description

technical field [0001] The invention relates to a driven vehicle axle which is coupled or can be coupled to an internal combustion engine and / or at least one electric machine which can optionally be operated as a motor or generator and which has a braking device. Background technique [0002] Such driven axles are used in hybrid or pure electric vehicles. A hybrid vehicle is a vehicle that is powered by at least one electric motor and at least one other engine. Currently, a hybrid vehicle mainly has an internal combustion engine and an electric motor. [0003] Hybrid electric vehicles, also known as hybrid vehicles, can be configured in different ways. A distinction is generally made between hybrid vehicles with series hybrid drives, parallel hybrid drives and vehicles with power split devices. In a series hybrid drive, the combustion engine drives an electric generator to generate electricity for charging an electric energy storage or directly drives an electric motor. ...
