Title: Impact drilling machine
Inventor: GEIS WILHELM DIPL ING
IPC: B25D16/00
Filed: 1984-12-14
Abstract: The subject matter of the invention is an impact drilling machine having a two-speed gear unit, operable by means of a shift lever, for setting different rotational speeds of the drive spindle as well as an actuating element for switching off the percussion. In order to prevent such an impact drilling machine from being capable of operation at maximum rotational speed during impact drilling operation, which would involve the risk of premature failure of the machine, the invention provides for such a spatial arrangement, allocation and configuration of the shift lever (34) for the speed setting and of the actuating lever (39) for switching the percussion on and off that these two levers prevent the "impact drilling" operating state at the higher spindle speed by mutual locking. <IMAGE>

Title: Hydrostatic drive for a vehicle
Inventor: WEIGLE DIETER DIPL ING
IPC: B60K6/12
Filed: 1985-04-20
Abstract: In a hydrostatic drive for a vehicle with at least two axles, a hydraulic motor (16, 19, 25, 28) with constant displacement is assigned to each driven wheel. The hydraulic motors are fed by a fixed displacement pump (11) which is driven by the internal combustion engine (10) of the vehicle. The hydraulic motors are connected appropriately in series and/or in parallel to the inflowing pressure medium during the shifting of the gears. For this purpose, two directional control valves (32, 36; 34, 35) are assigned to each drive axle. By means of the fixed displacement pump (11) an accumulator (39) connected to the high pressure line is also charged, which accumulator (39) can be used, for example, to drive two hydraulic motors (40, 46) for driving the fan and the alternator, which however are usually also fed from the high pressure side. In this way it is possible, by skilful dimensioning and circuitry of the pump and the hydraulic motors and corresponding graduation of the individual gears to run at the optimum level of efficiency of internal combustion engine and hydraulics. <IMAGE>
