The LSV is not set up in the factory with any particular suspension or brake pressures so these must be set by the vehicle manufacturer to the necessary values (LSV instruction plate). The setting ( diagram or LSV setting program) is made in a mechanical part and a pneumatic part.
Setting the pivot point (X)
- Determine the actuating cylinder travel with the help of the diagram
- Calculate the intermediate value with the formula
- Determine pivot position (X) for the balance arm from the pivot scale :
- pe1 = 6.0 bar pe2 empty = 2.0 bar.
With curve pe1 = 6.0 bar, the intersection point with pe2 = 2.0 bar is formed, connect the intersection point with the actuating cylinder scale, giving 24.5 mm actuating cylinder travel
- Suspension pressure loaded pe41, 42 = 5.0 bar, suspension pressure empty pe41, 42 = 1.5 bar, gives 5.14 intermediate value
- Vertically above the value of the calculated intermediate point, the pivot position (X) can be read off the pivot scale for the balance arm, giving 30 mm pivot point.
- Set the pivot point (X) corresponding to the value determined:
|Remove cover G, hold both of the nuts between the balance lever and the frame with the hexagonal spanner 14 mm, loosen the locknuts on the balance lever and fixed bearing with the hexagonal spanner 17 mm and set the pivot position to the calculated value X. First tighten the nuts on the fixed bearing, set up the balance arm (centrally between the return springs for the 90° - position to the long axis of the LSV; if necessary, remove any pre-tensioning in the return springs by turning the adjustment screw F to the left), tighten the nuts 17 mm on the balance lever with about 12-13 Nm torque.|
