Regulating/damping spring (R/D-spring)

Assembly mounted on the head of the lifting rod for damping the
aperiodic transient oscillation of the brake (special application:
Regulation braking).

Figure 7:

Regulating/damping spring (R/D-spring)

1 R-spring (TGL 35868)

2 D-spring (DIN 15430)



Damping of the load changes when the brake is applied



The R/D spring is only effective in conjunction with a C-spring.



The installation dimension “h1” of the thruster does not change.



When determining the operating point of the brake, the spring
characteristic curve must be taken into account.



Main application: ELHY
