Abstract

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.

First claim

The invention claimed is:

1. A military vehicle comprising:
a chassis including a passenger capsule, a front module coupled to a front end of the passenger capsule, and a rear module coupled to a rear end of the passenger capsule;
an axle supported by the rear module;
a suspension system positioned between the rear module and the axle, the suspension system including a first high-pressure gas spring, a second high-pressure gas spring, a first hydraulic damper, and a second hydraulic damper, wherein the first hydraulic damper and the second hydraulic damper are cross-plumbed to provide a hydraulic body roll control function;
a driveline including an engine supported by the front module, a transmission coupled to the engine, and a transaxle coupled to the transmission and the axle, wherein the transaxle includes a housing that functions as a structural component of the rear module, and wherein (i) the first high-pressure gas spring and the second high-pressure gas spring and (ii) the first hydraulic damper and the second hydraulic damper are directly coupled to the housing of the transaxle;
a generator driven by the engine to generate electricity; and
an export power kit coupled to the generator and configured to facilitate exporting power off of the military vehicle.
