A power distribution unit for a vehicle includes a fuel cell stack, a bracket connected to the fuel cell stack and including at least one mount adapted to be connected directly to a vehicle to directly interconnect the fuel cell stack to the vehicle, a connection feature, and a traction system communicated with the fuel cell stack and carried by at least one of the fuel cell stack and the bracket with the connection feature disposed between the traction system and said at least one of the fuel cell stack and the bracket so that the traction system is indirectly connected to the vehicle. In one implementation, the connection feature includes an elastomeric pad disposed between a housing of the traction system and a mount or the vehicle frame. The pad provides a so-called “soft mount” of the traction system to the vehicle.

A fuel cell system that employs one or more PTC ceramic heaters that do not need to be self-regulated, and thus will not require various control components, such as temperature sensors. The PTC ceramic heaters include a ceramic material that is designed for a particular temperature depending on the particular application. An electrical current is applied to the ceramic heater that generates heat as long as the temperature of the ceramic heater is below the designed temperature. If the ceramic heater reaches the designed temperature, then the resistance of the ceramic material goes up, and the current through the ceramic material goes down, so that the heater does not provide significant heating. Therefore, it does not need to be regulated.

A drive unit, such as a rear drive unit, for a motor vehicle, such as an all-wheel drive motor vehicle, includes, but is not limited to two drive shafts, of which one drive shaft serves for driving the one wheel and the other drive shaft serves for driving the other wheel of a motor vehicle. Also provided is a transmission operationally connected to the drive shafts, through which a drive torque acting on the input of the transmission can be divided or is divided into at least two output torques and through which the output torque of the transmission acting on the one drive shaft is reversible or is reversed in its operation direction relative to the output torque of the transmission acting on the other drive shaft.
摘要:
A process is disclosed for determining the vibration characteristics of a body by modal analysis. The body is made to vibrate at different frequencies and optical interference images of the body are recorded for the different frequencies. The interference images are analyzed on the basis of a mathematical/physical model, in view of the vibration characteristics at predetermined points, and the thus obtained information about the vibration characteristics of said points is subjected to a modal analysis.

A continuous process to oxychlorinate olefins and aromatics is described, comprising the conversion of olefins and aromatics as component (a) with oxygen and hydrogen chloride as component (b) in the presence of a solid cuprous/cupric salt catalyst in a reactor, characterized in that components (a) and (b) are fed separately from each other in spatial terms into reaction zones and regeneration zones of the reactor, where the reaction zone shows a higher concentration of the catalyst in its oxidized form at the solids entry point than at the solids exit point, and the regeneration zone shows a higher concentration of the catalyst in its reduced form at the solids entry point than at its solids exit point, and where component (a) is fed into the reaction zones and component (b) is fed into the regeneration zones.
摘要:
A method and a device for measuring dimensions of gaps and hollow spaces in motor vehicle body construction use a filler element which is introduced in a gap or a hollow space to be measured. The filler element is coupled to an ultrasonic testing device for accurately and consistently measuring the gap or hollow space.
