The invention relates to a method for applying sand to the inner radius of drum brake linings comprising the following steps: a) rolling a UV-curing adhesive onto the inner radius of a drum brake lining, b) applying a frictional grain, such as zircon sand, to the adhesive layer, c) removing the frictional grain not retained by the adhesive from the lining surface, and d) curing the coating by means of UV radiation.

Method for applying sand to drum brake linings

The invention relates to a brake shoe () for disk or drum brakes, which comprises a supporting plate () with a friction pad () attached thereto and at least one wear indicator (), characterized in that the wear indicator () has a wear sensor () for continuous or multi-stage measurement of the wear of the friction lining and a receiver and transmitter unit () for wireless signal transmission, the receiver and transmitter unit being a passive RFID (Radio Frequency Identification) or SAW (Sound Acoustic Wave) transponder.

The invention deals with a traveling or driving simulator and especially a rake test stand for vehicles with antiskid brake systems, with drive rollers assigned to the vehicle wheels to be tested and slippage members, with adjustable slippage characteristic for brake torque dependent change of the drive torque between the drive rollers and the vehicle wheels, being assigned to the drive rollers. The drive rollers are coupled with each other by their drive shafts and driven by the flywheel masses of the rotating parts. In operation, the drive rollers can be accelerated up to the testing speed by the vehicle present upon the brake test stand. The slippage members are designed as electric or hydraulic machines controllable independently of each other. Thus, a slippage characteristic for different roadway conditions can be realized for each vehicle individually in a simple and optimized manner.
