Retarder Brake System of a Vehicle Combination

摘要

A retarder brake system of a vehicle combination including an agricultural tractor and an electrically driven trailer includes a drive train with a combustion engine, a vehicle transmission downstream from the combustion engine, a mechanical drive axle of the agricultural tractor connected to a first gear output of the transmission, a first electrical motor generator unit coupled to a second gear output, and an electrical drive axle of the trailer. The electrical drive axle is driven by means of a second electrical motor generator unit. The generator units are electrically connected with one another via a direct current link. In a retarder operation, the second electrical motor unit is operated with a generator and the first electrical generator unit is operated with a motor. At least part of the gross retarder output requested on the electrical drive axle is dissipatively destroyed as a power loss within the drive train.

1. A retarder brake system of a vehicle combination including an agricultural tractor and an electrically driven trailer, comprising:
a drive train with a combustion engine; a vehicle transmission coupled to the engine; a mechanical drive axle of the agricultural tractor coupled to a first gear output of the transmission; a first electrical motor generator unit coupled to a second gear output; and an electrical drive axle of the trailer operably driven by a second electrical motor generator unit; wherein, the two electrical motor generator units are electrically coupled to one another via a direct current link; wherein, in a retarder operation, the second electrical motor generator unit is operated by a generator, and the first electrical motor generator unit is operated with a motor, where at least a portion of a gross retarder output requested on the electrical drive axle is dissipatively destroyed as a power loss within the drive train.
