Floor panel vibration is reduced by suppressing a mode in which an entire region surrounded by a plurality of frame members in a floor panel vibrates. Vehicle-body framework members having closed cross-section structures, and a panel member to which vibration is transmitted from an engine or/and a suspension via the vehicle-body framework members are provided. The panel member includes a flange portion having a planar shape on its outer peripheral edge and to which the vehicle-body framework members are joined along the panel outer peripheral edge; a curved surface portion that is curved such that a place closer to a panel central side bulges out more to a lower side in a continuous manner from a panel-central-side edge portion of the flange portion; and a flat surface portion that extends to the panel central side from the panel-central-side edge portion of the curved surface portion in a continuous manner.

A subframe mounting bush structure for improving NVH performance is provided. The subframe mounting bush structure includes an outer shell, a first bridge formed in the outer shell along a longitudinal direction, a second bridge formed in the outer shell along the longitudinal direction, a first inner shell positioned at a center of the first bridge, and a second inner shell positioned at a center of the second bridge.

An isolation mount assembly includes a rubber isolator formed to be seated within an aperture in a supported member, with an extension located on an exterior surface of the isolator; and includes a washer containing an aperture corresponding with a location of the extension. The isolator may include a through-hole and an inner sleeve, and be seated within a supported member. A method for temporarily securing a washer to a rubber isolator includes aligning an aperture in the washer to a corresponding securing feature on the isolator, inserting the securing feature through the aperture, pulling a detached end of the securing feature, pushing the washer towards the isolator until it makes contact with the surface of the isolator, and releasing the detached end of the securing feature. An exemplary method may include trimming or deforming an excess part of the extension after releasing the detached end.

A cab mount for attaching a frame to a body is provided to prevent a forcible movement of the body generated under the influence of vertical vibration of the frame. A first cab mount includes: a collar extending vertically; and an upper mount rubber and a lower mount rubber disposed to face in the upper-lower direction on an outer periphery of the collar. The collar is attached to a body of a vehicle by being inserted into an attachment hole of a ladder frame of the vehicle while a peripheral part of the attachment hole is positioned between the upper mount rubber and the lower mount rubber. The upper mount rubber is spaced apart from the ladder frame in the upper-lower direction by a first predetermined distance while the lower mount rubber is spaced apart from the ladder frame in the upper-lower direction by a second predetermined distance.

A first body cross-member is disposed on body mounts and fixed to the body mounts through outer brackets and mount bolts that are fastening members. A battery and a cooling blower that is a battery accessory provided on an outer side of the battery in a vehicle width direction are installed on a vehicle body, between a pair of rockers. The rockers have a closed cross-sectional structure, and a brace that is a reinforcing member is housed in a battery flanking portion of each rocker that is a portion corresponding to the cooling blower in position in a vehicle front-rear direction.

A refuse vehicle includes a frame structure, one or more axle assemblies, a body, one or more cab supports, a plurality of brackets, and a battery frame. The one or more axle assemblies are coupled to the frame structure and extend laterally from the frame structure. The body is coupled to the frame structure and extends along at least a portion of a length of the frame structure. The body includes an upper section, a middle section, and a lower section. The one or more cab supports extend along the length of the frame structure and are configured to receive a cab of the refuse vehicle. The plurality of brackets are fixedly coupled to the frame structure and the body. The body and the battery frame cooperatively define a unitary body.
