Abstract: A method for the manufacture of a bulkhead of a motor vehicle body and method for the manufacture of bulkheads of motor vehicle bodies of different types of motor vehicles. The front wheel arches of the motor vehicle body are at least partly formed by the bulkhead of the motor vehicle. A component with a spatial structure is manufactured from a two-dimensional metallic semi-finished product by forming, wherein the component forms at least part of the bulkhead. The component manufactured by the forming forms at least a large part of the bulkhead in relation to the area of the projection of the bulkhead in the longitudinal direction of the motor vehicle and extends at least over sections of both front wheel arches of the motor vehicle body.

Abstract: A method for assembling a motor vehicle body, wherein the motor vehicle body has a front end structure with a bulkhead and a body area arranged in the longitudinal direction of the motor vehicle behind the bulkhead. The front end structure is pre-assembled separate from the body area before connecting the front end structure to the body area located behind the bulkhead. The separation between the pre-assembled front end structure and the body area is immediately in front of or behind the bulkhead.

Abstract: A control valve for an indirectly acting compressed-air brake of a rail vehicle includes a pneumatic relay valve for controlling a brake cylinder pressure via a pilot-control circuit for generating a temporally defined pilot-control pressure for the proportional activation of the relay valve, wherein, connected upstream of the pilot-control circuit, there is provided a device for generating the braking and release times of the compressed-air brake, wherein the device for generating uniform braking and release times of the compressed-air brake has mechanisms for realizing a volume flow with constant pressure change for the compressed-air supply and the deaeration of the pilot-control circuit.
