Coupling device with overrun brake
WARNING
Danger from incorrectly fitted coupling device / DIN towing eye!
An incorrectly fitted coupling device / DIN towing eye can lead to failure of
the overrun brake and thus to traffic accidents.
−
The coupling device / DIN towing eye must be adjusted to the coupling
height of the towing vehicle.
−
The coupling device / DIN towing eye must be in a straight line to the
towing vehicle's coupling device (parallel to the ground)
Figure 7:
Coupling device
The chassis is optionally designed for transport with a ball coupling (1),
usually for passenger cars, or a DIN towing eye (2), usually for trucks or
vans.
The integrated overrun brake brakes the trailer when the towing vehicle is
braked and on steep downhill runs.
When braking the towing vehicle or driving downhill, the draw bar of the
overrun device is pushed in, depending on the magnitude of the draw bar
force. This causes the brake to be applied.
The brake also responds initially during reversing. However, the braking
effect is almost cancelled by the reverse rotation.
