In one or more examples, the trunnion mount includes a rubber bearing that is directly vulcanized on at least one of the bearing surfaces and/or wherein the ring portion is formed as a separate element from a mounting portion of the support element and connectable thereto via axial screws.

Two oil coolers (30, 32) are disposed so as to face each other in a front half of the inside of a heat exchanger chamber (26) defined in an upper revolving body (5), one oil cooler (31) is disposed in a rear half, and a space (E) formed between the oil coolers is used as work and passage spaces. Outside air as cooling air is allowed to pass through the respective oil coolers (30 to 32) by cooling fans (35), and cooling air that has passed through each of the two oil coolers (30, 32) disposed so as to face each other is made to mutually collide, and is discharged to the outside through a side outlet (38) of a front wall (26a) and a first upper outlet (39) of a ceiling (26e) of the heat exchanger chamber (26). Cooling air that has passed through the other one oil cooler (31) is made to collide with a left side wall (26c), and is discharged to the outside through a second upper outlet (40) of the ceiling (26e).

A swiveling working machine includes a swivel base; a working device provided on a front side of the swivel base; a battery unit; an electric motor that is driven by electric power output by the battery unit; and a hydraulic pump that delivers a hydraulic fluid by driving of the electric motor. The battery unit is disposed at a rear portion of the swivel base. The electric motor and the hydraulic pump are disposed sideward of the battery unit side by side in a front-rear direction.

A cab capable of shielding solar radiation comprises a pair of front pillars and a pair of vertical beams; a front window glass member mounted movably along guide rails formed along the front pillars and the vertical beams, between a closing position for closing a front window formed between the front pillars and an opening position for opening the front window accommodated between the vertical beams; a roll screen and a winding member, wherein the winding member is disposed behind the inner surface of the front window glass member positioned at the closing position and in front of the front end of the front window glass member positioned at the opening position and on the outer side of the pair of guide rails; and a holding means attached to the front pillars and configured to releasably hold the leading end of the screen.

Provided is a work machine that, within the limit of not harming dynamic stability, can perform work utilizing the impact generated when a cylinder driving a front work implement collides with a stroke end. A drive control system 34 includes: a stroke end distance calculation and evaluation section 34c that determines whether or not it is possible for cylinders 20A and 21A to collide with a stroke end; a dynamic center of gravity position prediction section 34d that, when the stroke end distance calculation and evaluation section determines that it is possible for the cylinders to collided on the stroke end, predicts a trajectory of the dynamic center of gravity position of a hydraulic excavator 1 from a time when a decelerating operation of the cylinder starts to a time when the cylinder stops; and an allowable velocity changing section 34f that changes the allowable velocity of the cylinder according to a minimum distance from the trajectory of the dynamic center of gravity position predicted by the dynamic center of gravity position prediction section to a tipping line of the hydraulic excavator.

Embodiments of the present disclosure relate to a method and apparatus for controlling vehicle driving. The method includes: generating a global path of a driving site of a vehicle; executing following controlling: generating a local path of a site in front of a current position of the vehicle based on the global path, the local path following a direction of the global path, controlling the vehicle to drive along the local path until reaching an end point of the local path, determining whether the vehicle reaches an end point of the global path, and terminating the controlling if the vehicle reaches the endpoint of the global path; and continuing, in response to determining the vehicle failing to reach the end point of the global path, executing the controlling.

A mechanical stabilization system for a battery assembly is disclosed. The system includes an actuator and a stabilizer that are configured to work in concert. The actuator and stabilizer are disposed in a housing of the battery assembly. The system may be implemented by depression of the actuator disposed in the housing, which causes the stabilizer to retract a support post into the housing. The depression can occur during a docking operation of the battery assembly with a lift mechanism for an electric vehicle. When the actuator is released, the support post automatically reverts to its previous, deployed state. The support post is configured to maintain the battery assembly in a stable configuration when the battery assembly is separated from the electric vehicle.

An image acquisition unit acquires a captured image of surroundings of a work vehicle. A detection unit detects an obstacle around the work vehicle. A display control unit generates a signal for displaying an obstacle-identifying display at a position related to an obstacle having high detection accuracy among a plurality of obstacles detected in a region corresponding to the captured image when the plurality of obstacles is detected by the detection unit, the detection accuracy indicating a certainty of the obstacle.

A wheeled work vehicle includes: a transmission transmitting the rotational power of a traveling hydraulic motor to wheels; a traveling control valve having an interruption position that interrupts supply of hydraulic fluid from a hydraulic pump to the traveling hydraulic motor; a shift changeover valve that shifts the speed stage of the transmission by the position of the shift changeover valve being selectively switched; and a controller that controls the traveling control valve and the shift changeover valve. The controller switches the traveling control valve to the interruption position, then switches the position of the shift changeover valve such that the speed stage of the transmission is shifted to the low speed stage, and switches the traveling control valve from the interruption position to an original position side before the switching in a case where the controller shifts the transmission from the high speed stage to the low speed stage.

The present invention provides a construction machine, which includes a cabin in which a driver is seated, the construction machine including a ventilated seat having fans, an air conditioning device configured to adjust an internal temperature of the cabin, and ducts extending from the air conditioning device and configured to guide an air flow, in which the ducts branches to include a first duct extending toward an upper side of the cabin, and a second duct extending toward a rear side of the ventilated seat. Therefore, it is possible to improve a cooling effect that the driver actually feels.
