Disclosed herein is an engine compartment soundproof cover device of a cab-over truck. The engine compartment soundproof cover device includes a soundproof cover, side covers, and a plurality of expandable connectors. The soundproof cover is installed below a cab in which a driver is seated and is configured to cover an upper portion of an engine compartment. The side covers are installed on chassis frames of both sides of the engine compartment and configured to come into contact with a lower end of the soundproof cover to seal both sides of the engine compartment. The plurality of expandable connecters is configured to connect the soundproof cover to a lower portion of the cab and capable of expanding toward the side covers to allow the lower end of the soundproof cover to be pressed against the side covers.

A mechanical linkage between operator input devices and actuators including a junction having a first portion operably coupled to an operator input device and a second portion operably coupled to an actuator. The first and second portions of the junction are connected when a cab is in an operating position and disconnected when a cab is in a service position. When connected, the first and second portions create a solid connection between the operator input device and the actuator. When the first and second portions are disconnected, the operator input will be not be operably coupled to the actuator. Movement of the cab to the operating position will cause the first and second portions to become connected and movement away from the operating position will cause the first and second portions to become disconnected.

A commercial motor vehicle having a chassis, an engine compartment defined between parallel elongate beams of the chassis, and a driver cabin positioned at least partially over the engine compartment. The driver cabin being supported on the chassis by spaced resilient suspension devices, and includes an upper cabin part and a lower cabin part. The upper cabin part is tiltable to allow access to the engine compartment by being hinged about a lower edge, while the lower cabin part remains associated with the chassis when the upper cabin part is tilted. The lower part of the driver cabin is supported by the resilient suspension devices.

Aspects of the disclosure relate to a vehicle with extended length air deflectors. The vehicle includes a chassis comprising a front axle and a rear axle. The vehicle further includes a cab mounted to the chassis. The cab has a first sidewall, a second sidewall, and a rear wall. The vehicle further includes a first air deflector positioned proximate to the first sidewall. The first air deflector includes a body having an outer surface and a front edge configured to be positioned proximate the cab, the outer surface of the body of the first air deflector aligned with an outer surface of the first sidewall in a deployed position. In certain embodiments, a front edge of the first air deflector is offset from the rear wall to define a first gap. In certain embodiments, the first air deflector is mounted to the chassis of the vehicle.

An agricultural machine, preferably a combine harvester, which has a pivoting vehicle cab. The cab is pivotable relative to the main frame of the machine, about an axis of rotation transverse to the direction of travel of the machine. The cab is pivoted to allow an operator to view a front coupling of the machine, to observe the attaching or detaching of a work implement to the front coupling.

A work vehicle includes an operator cabin, a transmission-supporting frame, and a mounting assembly. The mounting assembly includes a first mount configured to couple to the operator cabin, and a second mount configured to couple to the transmission-supporting frame. The first mount includes a first plate, and the second mount includes a second plate. The first plate and the second plate are coupled to one another at an interface, and at least one of the first plate and the second plate are configured to deform proximate to the interface to separate from one another when under tension during a roll-over event.

A work machine comprising a main body and a cab riser. The cab riser includes a cab and a frame comprising a first plate to contact a second plate provided on the main body in a first position which the cab is uprightly positioned on the work machine. The first and the second plate are coupled together to sandwich a key plate in the first position, the key plate being disposed in a space created by a first recess on a lower surface of the first plate and a second recess on an upper surface of the second plate, the second recess being aligned with the first recess vertically in the first position, and the key plate includes a first contact surface as a slope surface and a top surface being adjacent to the slope surface in the cross sectional view of the key plate.
