Embodiment Construction

[0076] A drive arrangement for a vehicle, in particular a motor vehicle, comprises at least one electric machine 1, a drive shaft 2a, a main service brake 3a and an additional service brake configured according to the invention as a fluid clearance brake. An additional brake or an additional service brake is a brake that supplements the main service brake and not, for example, a parking brake. Rather, the supplementary brake should be used to supplement the main service brake, ie it should ultimately allow additional deceleration of the drive wheels when the vehicle or drive is moving.

[0077] The drive preferably has a transmission 4 , a first drive shaft 2 a with a first drive wheel 5 a and a second drive shaft 2 b with a second drive wheel 5 b. The first drive shaft 2a is preferably arranged between the transmission 4 and the first drive wheel 5a, while the second drive shaft 2b is preferably arranged between the transmission 4 and the second drive wheel 5b.

Abstract

The invention relates to a drive device for a vehicle, comprising at least one electric machine (1), in particular an electric motor, having a rotor (R) and a stator (S), a drive axle (2) and a main service brake (3), the drive device being equipped with an additional service brake in the form of a fluid gap brake, comprising a fluid gap (6) which is situated between the rotor (R) and the stator (S) and can be flooded with a fluid to achieve a braking effect. The invention also relates to a vehicle having a drive device having a fluid gap brake and to a method for braking a drive device by means of the fluid gap brake, characterized by the following method steps: flooding the fluid gap with fluid from a reservoir by means of the flooding device; emptying the fluid gap of fluid into a reservoir by means of the drainage device.

Description

technical field [0001] The invention relates to a drive for a vehicle according to the preamble of claim 1 , a vehicle according to claim 16 and a drive for a brake drive according to claim 17 method. Background technique [0002] A drive device for a vehicle mainly includes an electric motor (especially an electric motor), a drive shaft and a service brake. Via a transmission, if necessary, the drive force from the electric motor is transmitted to the drive shaft, which in turn drives the wheels. The main service brake (overflow device, Flutungseinrichtung) is a brake that ensures deceleration (negative acceleration) of the driven vehicle during driving operation. For this purpose, so-called friction brakes are usually used. [0003] By law, the service brakes used on vehicles must be friction brakes. For extreme cases, braking systems are usually designed for negative accelerations above the legal norm. For this range, therefore, other (non-friction) braking systems a...
