Mechanical unit e.g. articulation bearing, fixing arrangement for motor vehicle, has reinforcement unit with lower wall having holes coinciding with holes of side rail, and discharge opening coinciding with opening of lower wall of rail

摘要

The arrangement has a side rail (14) with a tubular section having a lower wall (18) at its end part. A stiffening unit has a common reinforcement unit (24) with a lower wall (26) fixed on the wall (18) and having two holes (28) coinciding with fixation holes of the wall (18). A discharge opening (32) arranged in the wall coincides with an opening in the wall (18) for discharging condensation products formed in the rail.
