Abstract: A vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a powertrain coupled to the chassis, a cab coupled to the chassis, a rear module coupled to the chassis behind the cab. The powertrain is configured to drive at least one of the front axle or the rear axle. The rear module is selectively reconfigurable between a plurality of configurations.

Abstract: A vehicle includes a chassis, a suspension system coupled to the chassis, a front axle, a first rear axle, and a second rear axle coupled to the chassis by the suspension system, and a powertrain coupled to the chassis and at least one of the front axle, the first rear axle, and the second rear axle. The powertrain is configured to drive the at least one of the front axle, the first rear axle, and the second rear axle. The chassis, the suspension system, the front axle, the first rear axle, and the second rear axle provide a payload capacity rating of at least 1,750 pounds. The vehicle has an overall width between 60 inches and 80 inches.

Abstract: A vehicle steering system includes a steering input device, a front steering subsystem, a rear steering subsystem, a first force transmission route, a steering control mechanism, a second force transmission route, and a third force transmission route. The front steering subsystem is coupled to front motive members to steer the front motive members based upon movement of a front steering subsystem input shaft. The rear steering subsystem is coupled to rear motive members to steer the rear motive members based upon movement of a rear steering subsystem input shaft. The first force transmission route extends from the steering input device to the front steering subsystem input shaft, wherein force is transmitted from the input device to the front steering subsystem input shaft to steer the front motive members. The steering control mechanism has a movable input member and a movable output member.

Abstract: The vehicle steering system includes front vehicle motive members, rear vehicle motive members, a steering input device, a front steering subsystem, a rear steering subsystem and a rear steering control mechanism. The front steering subsystem is operably coupled to the steering input device and coupled to the front motive members to steer the front motive members. The rear steering subsystem is coupled to the rear motive members to steer the rear motive members. The rear steering control mechanism includes a movable input member coupled to the steering input device so as to move in response to input from the device and a movable output member coupled to the rear steering subsystem. The rear steering subsystem adjusts steering of the rear motive members in response to movement of the output member.

Abstract: A modular anti-sway bar assembly for heavy duty vehicles. The anti-sway bar has multiple components including a main torsion bar which is equipped at each end with a splined connecting surface. The splined ends of the main torsion bar allow it to be easily disconnected and removed from the vehicle. Each of the splined ends of the main torsion bar is gripped by an arm, which is generally horizontally oriented and which is connected by a vertical link to a wheel end. The main torsion bar is guided along its length and restrained from axial motion by a pair of support bushings, each of which is held in a pocket in a suspension side plate. The main torsion bar passes through openings in the side plates.
