Ausco Products

Ausco pioneered and patented the Spring-Applied Hydraulically Released Multi-disc Brakes

in 1971. Today, their Engineering, Design, Test & Development, and Production capabilities

are among the best in supplying brakes to the off-highway industry. Because their brakes

are easily designed into power transmission systems they have many engineering features

that translate into important user and specifier benefits. For example:

More than 100 models are standard.
All models have standard SAE J744 mounting flange dimensions.
They operate on either charge pressure or system pressure up to 3000 PSI.
Complete self-contained package - no extra brackets and no shimming required.
Spring-Ioaded and hydraulically released.
Most models have bearing-supported shafts.

Their Multi-disc Brakes are used both on Construction, Mining, Agriculture, Lifting, Industrial and Marine equipment.

Continuing to bring you the latest in heavy-duty brake technology and recognizing the advantages of wet brake technology, Ausco engineers applied their brake design expertise to develop the New Generation line with excellent benefits:

Reduced size
Improved cost
Increased pressure capability
Less corrosion (WET)
Longer component life (WET)

Multi-Disc Brake

The Ausco Multi-Disc Brake is spring loaded to apply the brake, and hydraulic pressure is required to release the brake. Normal operation is to have the brake pressurized in the released position with the vehicle hydraulic system running.

Any function, which reduces the hydraulic system pressure below the release pressure of the brake, will allow the springs to apply the brake.

Multi-Disc Brake with Service Brake

This brake combines the features of the Ausco Multi-Disc Brake and a limited service brake. This is typically a low speed, low energy application of the service brake. In normal operation, the release piston is pressurized, releasing the brake. Pressure applied to the service pistons develops brake torque proportional to the applied pressure.

MULTI-DISC BRAKE WITH ONE-WAY CLUTCH

This brake combines the features of the Ausco Multi-Disc Brake with the capability of the brake shaft to freewheel in one direction while the brake is applied. In winch applications, the one-way clutch allows rotation to raise the load, even though the brake is applied.

When the load is stopped or if pressure is lost due to a failure in the hydraulic system, any reverse rotation engages the clutch and the load is held by the applied brake.

No incremental dropping of the load is experienced. While lowering the load, the brake must be released and the control must be provided by a counterbalance valve or other suitable hydraulic control. The brake then assumes normal spring-applied hydraulic release operation.

Seals: Double lip to prevent contamination of sump cooling oil

Piston: Improved design for superior life at higher pressure

Friction Discs: "Heavy Duty Graphic Paper" for wet sump applications. Superior energy capability, high and stable coefficient of friction and smooth engagement.

Shaft: Increased number of spline teeth to reduce tooth loading

Bolts: Higher grade which allows for increased cycle loading

LONG LASTING PERFORMANCE

Completely sealed and enclosed, Ausco's wet multi-disc parking brake keeps out corrosive environments so they don't reduce the life of the brake. Dirt, mud, water, sap, pulp acids, corrosive hazards - the sealed design takes less maintenance and gives performance that exceeds government standards. Performance far beyond any exposed caliper brake.

REPLACES SEVERAL SEPARATE COMPONENTS

Because this sealed brake mounts at the articulation joint, it can replace the separate front bearing carrier, caliper brake, disc and all mounting hardware. You cut component inventory, simplify production and reduce assembled cost.

PROVEN DESIGNS TO FIT YOUR VEHICLE

Current models span torque ranges from 17,000 Ib.-in. to 102,000 lb.-in., but Ausco engineers can design a specific brake for your articulated vehicle without a long development cycle.
