ABSTRACT:
A motor vehicle which is more particularly adapted for stop and go traffic conditions such as a city omnibus plying on a regular service, a garbage collection vehicle or the like has a drive arrangement including a driven rear axle connected with an IC engine and a variable speed transmission, is fitted with a braking energy recovery means in the form of a self-contained system which is only connected with the variable speed transmission for charging and discharging of a high pressure accumulator. This coupling operation is performed by a clutch operated in accordance with certain operating conditions. One side of the clutch is joined to a secondary output of the variable speed transmission and the other side is connected with the drive shaft of a hydraulic transducer, of which only one is required. Owing to the fact that the braking energy recover means may be switched off smooth and trouble-free operation of the motor vehicle is possible using its normal drive means even if the braking energy recovery means is defective or has a faulty function.
