Resistance welding device comprises an energy supply provided by a main transformer (1) and secondary transformers (2, 3), in which all transformers are connected together by an alternating voltage intermediate circuit (5).

The unit has a trailer brake valve (20) to apply braking pressure, with a pressure connection (P) to a pump (2), a return connection (R) to a tank, and a brake connection (B). The valve is actuated dependent upon the brake pressure of a towing vehicle. An ...

The drive has at least one hydraulic pump (3) and several hydraulically operated hydraulic motors (6-9) connected to the pump, whereby each motor has an associated revolution rate sensor (20-23) connected to a control unit (24). A braking device (26-29) th...

The circuit has a converter unit (2) for converting an input voltage (VE) into an output voltage (VA) with a defined output potential and a capacitor (5) for providing an input if the input voltage fails so that the output voltage is held for a defined per...

The drive has at least one hydraulic pump (3) and several hydraulically operated hydraulic motors (6-9) connected to the pump, whereby each motor has an associated revolution rate sensor (20-23) connected to a control unit (24). A braking device (26-29) th...

The electromechanical brake actuator has a housing within which is contained a motor driven actuating unit. An axially movable spindle rod extends from the housing, and connections (8,14) for brake operating elements are formed on the housing. The housing ...

The braking system (1) has an actuator (2) which incorporates a piston (8) loaded by a spring (22), made of Belleville washers (32), toward its brake application position. An annular chamber (18) may be filled with fluid under pressure to push the piston a...
