Eurosatory 2018: Alcon Brings CIR55

Declares CIR55 bespoke heavy armoured vehicle brake caliper “production ready”

Alcon Components Ltd. declared their new bespoke armoured vehicle brake caliper “production ready” at Eurosatory in Paris this week. First unveiled to the European and wider global markets at the DSEi exhibition, London in September 2017, and then to the US market at AUSA in October 2017, the new CIR55 caliper has been designed and developed to fit 8×8 type military vehicles operating at 30-40+t GVM. 

Since its launch, the caliper has successfully undergone an extensive testing and validation process to meet all of the requirements to enter production. The CIR55 significantly increases braking performance and reduces both weight and cost in comparison to existing alternatives, according to the company.

Intended as a direct alternative to the current defence industry standard twin-caliper arrangement, the production ready CIR55 brake caliper features a custom designed eight-piston, four-pad configuration with an option for either 60mm or 64mm diameter pistons. The caliper can be used on disc diameters of 400mm to 410mm and the centre split design allows caliper variants to be available for a variety of disc thicknesses. The fully hanging, high friction pads are fitted with an anti-rattle system and the caliper and seals are protected to cope with the harsh military environment.

Alcon expects the caliper to be used in a single-fit per wheel station configuration with a total of 8 calipers in use on a typical 8×8 armoured vehicle. It is also expected that the CIR55 could be used on heavy 6×6 and 4×4 military vehicles, where appropriate. The immediate benefits on offer are a weight reduction in the region of 50kg per vehicle, a cost reduction and improved cooling. The specific performance benefits when directly compared to the current market leading single-fit caliper solutions are: 11.5% larger piston area; 34% more pad area; 33% additional torque capacity; and all delivered with a 7% weight saving. The smaller swept profile of the CIR55 also means it can be fitted into a tighter space envelope.

The brake was developed in cooperation with AxleTech, whose extensive experience in the design, manufacturing and application of military products, contributed to an optimal design. The brake is being offered as part of AxleTech`s brake portfolio under the Hydraulic Disc Brake family HD860 series.

Visitors to the Eurosatory exhibition are able to view the Alcon CIR55/AxleTech HD860 brake among AxleTech’s products on stand #B648 in the USA Pavilion. In addition, there are Alcon brakes fitted to over 10 vehicles or other applications being exhibited across the event.

Eurosatory 2018 is showcasing the future of innovation across the land forces sector and MONCh (Moench Online News Channel at www.monch.com) brings together key developments from the show.
