A frame assembly for supporting and mounting a box compartment over and around a flat bed of a flatbed tow truck is described. The frame assembly includes a frame attached to a chassis of a flatbed tow truck. The frame includes at least one left and at least one right side support beams, at least one left and at least one right horizontal connection beams, two or more left side and two or more right side vertical support beams, at least two cross-beams, and at least one vertical connection beam. One or more of the at least two cross-beams is connected to the chassis and is further connected at each of its ends to the left and right side support beams. Each vertical connection beam is connected to either the left or right horizontal connection beam and is oriented generally vertically for attachment of a box compartment to the frame.

A cab chassis vehicle and a method of assembling a cab-chassis vehicle are provided. A chassis is sub-assembled by connecting a mounting bracket for a truck body to a frame rail via a fastener, installing a chassis-side vehicle harness, and installing a chassis-side body wiring harness. A cab is sub-assembled by installing a connector plate to cover an aperture on an outer panel of the cab, installing a cab-side body wiring harness, connecting the cab-side body wiring harness to the connector plate, and installing a cab-side vehicle harness. The cab is assembled to the chassis to provide a cab-chassis vehicle by connecting the chassis-side body wiring harness to the connector plate, connecting the chassis-side vehicle harness to the cab-side vehicle harness.

A device together with an assigned working machine for decoupling vibrations between two systems (2, 4) in the form of spring-mass oscillators, of which one system (2) is assigned to a motion machine and the other system (4) is assigned to an operator operating the motion machine. The other system (4) at least partially performs motions about a transverse axis (Q) during driving motions of the motion machine and in doing so is subject to vertical motions in the direction of a vertical axis (z) at an absolute vertical speed (v.sub.z1,1) serving as an input variable of control devices and/or regulating devices. Those devices control a damping system (8) of the one system (2) and/or the other system (4) to compensate for the vibrations. The respective pitch motion of the other system (4) is detected by at least one rotation rate sensor. The respective measured value (ω.sub.1) of the sensor, preferably amplified by only a predeterminable factor (L.sub.1), results in the absolute vertical speed (v.sub.z1,1) as input variable.

A zero-emission configurable medium/heavy duty class electric truck is disclosed that uses high-voltage, battery-powered electrical energy for both motive power and auxiliary powered unit power. In embodiments, the electric truck includes a central frame having a pair of main frame rails configured to support at least two battery modules, a front subframe configured to support a front axle assembly and a cab, and a rear subframe configured to support at least one rear axle assembly and a rear payload module selected from one of the set of multiple configurable rear payload modules. In embodiments, at least one of the front axle assembly and the rear axle assembly include an electric motive motor powered by a battery management system configured to manage generation and distribution of alternating-current (AC) electrical power from the at least two battery modules to the at least one electric motive motor to provide motive power to the zero-emission configurable electric truck and to at least one auxiliary power unit (APU) to provide auxiliary power to the rear payload module.

A utility vehicle includes at least one front ground-engaging member, at least one rear ground-engaging member, and a frame assembly extending along a longitudinal axis and supported by the at least one front ground-engaging member and the at least one rear ground-engaging member. The utility vehicle also includes an operator area supported by the frame assembly and a powertrain assembly supported by the frame assembly. The powertrain assembly includes at least an engine and a gearbox operably coupled to the engine. The utility vehicle also includes a cooling assembly fluidly coupled to at least the engine and supported by a front portion of the frame assembly. The cooling assembly includes a radiator with a lower portion positioned forward of an upper portion of the radiator.

The present disclosure relates to a frame assembly of a heavy duty vehicle including an operator cabin. The frame assembly may comprise a superstructure frame having a first flange at least partially protruding from the cabin supporting frame mounting portion and having a collar and a plurality of first flange bores. The frame assembly may further comprise a cabin supporting frame having a first mounting section including a plurality of first mounting section bores, a first guiding member, and a second guiding member. The first and second guiding members may be configured to engage the collar for safely guiding the cabin supporting frame relative to the superstructure frame into a final assembling in which the plurality of first flange bores may be aligned with the plurality of first mounting section bores.

This disclosure details exemplary pillar-to-box rail-to-cab back structural joints for unibody vehicles. An exemplary structural joint of a unibody vehicle may include a pillar assembly and a box rail assembly that intersects the pillar assembly and extends continuously up to a door opening flange of the pillar assembly. The pillar assembly and box rail assembly may establish a beam-to-beam connection of the structural joint. A cab back assembly may be secured relative to the pillar assembly and the box rail assembly to establish a third portion of the structural joint. Various spot welds may be provided for joining the various components of the structural joint.
