Service brakes, safety brakes, emergency brakes welded steel structure in accordance with standards DIN 15435
APPLICATIONS
• Service brake
• Safety brake
• Emergency brake
ORIGINAL EQUIPMENT
• Welded steel structure according to DIN 15435 - epoxy resin painting (2 coatings) - RAL 3000 final colouring.
• Manganese phosphated pins.
• Self-lubricating bushes on main joints.
• Light alloy drums with asbestos free bonded linings
•Friction coefficient μ=0,42
• Braking torque scale indicator.
OPERATION
• The drum brakes WESTCAR type A are negative.
• The braking force is obtained by means of a spring that, through a suitable system of levers, transmits its
amplified action to the braking pads.
• An electrohydraulic or pneumatic thrustor makes an opposite force to the spring, causing the pads to open,
therefore the brake to release.
• The braking force of the linings against the drum can be modulated by adjusting the spring.
• Braking torque changes depending on braking force modulation.
