Publication number: 20220144227Abstract: A military vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a suspension system. The suspension system include a front suspension assembly and a rear suspension assembly. The front suspension assembly is positioned between the chassis and the front axle. The rear suspension assembly is positioned between the chassis and the rear axle. Each of the front suspension assembly and the rear suspension assembly includes a first spring, a second spring, a first hydraulic damper, and a second hydraulic damper. The first hydraulic damper and the second hydraulic damper of at least one of the front suspension assembly or the rear suspension assembly are cross-plumbed to provide a hydraulic body roll control function and eliminate the need for an anti-roll bar.Type: ApplicationFiled: September 1, 2021Publication date: May 12, 2022Applicant: Oshkosh Defense, LLCInventors: Don Verhoff, Gary Schmiedel, Chris Yakes, Rob Messina, Brian Wilkins, Kent Schulte, Daniel R.

Publication number: 20220144226Abstract: A military vehicle includes a brake positioned to facilitate braking a tractive element, a brake housing defining an inner volume, a piston separating the inner volume into a first chamber and a second chamber, a rod extending through an end of the brake housing and coupled to the piston where the rod is positioned to selectively engage with the brake to inhibit movement of the tractive element, a resilient member positioned within the inner volume and configured to generate a biasing force against the piston such that the rod is biased into engagement with the brake, and an air-to-hydraulic intensifier coupled to the brake housing. The air-to-hydraulic intensifier is configured to receive a supply of air and provide a hydraulic fluid to the brake housing based on the supply of air to overcome the biasing force to disengage the rod from the brake to permit movement of the tractive element.Type: ApplicationFiled: August 31, 2021Publication date: May 12, 2022Applicant: Oshkosh Defense, LLCInventors: Don Verhoff, Gary Schmiedel, Chris Yakes, Rob Messina, Brian Wilkins, Kent Schulte, Daniel R.
