Wall impact test for trailer coupling devices
Testing standard:
EP 83 020.10
Product information
Test to check the safety and stability of trailer coupling devices in the event of a wall impact. This test is used to check the strength and operational safety of trailer coupling devices, e.g., trailer hitches, under simulated reverse driving loads.
A vehicle with a trailer coupling device attached is driven backwards into a solid wall in order to record the forces acting on the coupling and attachment points.
The test involves measuring force and displacement curves, high-speed recordings of the ball bar behavior, and documentation of the continued torque of all screw connections relevant to operational safety.
The test is carried out with both the trailer coupling folded out and plugged in to cover different operating conditions.
The aim is to ensure that the design can withstand these loads without deformation, breakage, or detachment, and that the operational safety of the trailer coupling is guaranteed.
