5.3 Description of the brake
Depending on the scope of supply, the planetary gearbox is equipped with a wet-
running, integrated static multiple-disk brake (multiple-disk parking brake).
Risk caused by the failure of the static multiple-disk parking brake!
The use of the static multiple-disk parking brake for braking the vehicle may cause
its destruction.
Operate the static multiple-disk parking brake only after a complete stop of the
vehicle.
Danger of delayed holding of the static multiple-disk parking brake!
The delayed application of the static multiple-disk brake may cause the vehicle to
roll away accidentally.
Make sure that the brake line of the static piston is not pressurized within 0.5
seconds.
The multiple-disk brake is a hydraulically released brake. The multiple-disk brake is
used as a parking brake as standard. The parking brake (static multiple-disk parking
brake) is applied via the brake release connection.
The static multiple-disk parking brake acts negatively, i.e. it is released by means of
pressure fluid and applied by spring action when pressureless.
5.4 Circulating oil lubrication or external oil cooling / oil pump
The planetary gearbox is equipped on the motor side with connections for a
circulating oil lubrication. The planetary gearbox may only be operated in a closed oil
cooling circuit (a separate oil cooling circuit is required for each gearbox in the
vehicle). For information on the permissible operating conditions, refer to the
planetary gearbox dimensioned drawing in the appendix D "Technical data /
Drawings" of the material number-specific operating instructions.
The oil cooling circuit requires an external oil pump and an oil cooler for each
gearbox in the vehicle.
The machine or vehicle manufacturer ensures specification conformity and reliability
of the external oil cooling. For defects on connections and any other consequences
resulting therefrom, Rexroth assumes no liability for material defects and is
exempted from any claims made by third parties.
