摘要： A collision avoidance system (200) for a work machine (100) includes at least one sensor (202) configured to generate a signal (I3) indicative of a presence of at least one obstacle (142, 302, 402) in a surrounding area (140) of the work machine (100), at least one imaging device (204, 206, 208, 210), a display device (212), and a controller (214). The controller (214) receives the signal (I3) indicative of the presence of the obstacle (142, 302, 402) and determines a position of the obstacle (142, 302, 402) relative to the work machine (100) based on the signal (I3) received from the sensor (202). The controller (214) generates a first control signal (O1) to prevent a movement of the work machine (100), halt the movement of the work machine (100), or reduce a velocity of the work machine (100) based on the determination of the position of the obstacle (142, 302, 402). The controller (214) generates a second control signal (O2) for displaying an updated display view (300, 400) that provides a visual indication of the presence of the obstacle (142, 302, 402) in the surrounding area (140) of the work machine (100).

摘要： A bearing assembly (128) for a turbocharger (12) installed within a turbocharger housing (30) between a turbine wheel (32) and a compressor impeller (36) mounted for rotation together on a turbocharger shaft (34) includes a journal bearing (152) disposed on a corresponding portion of the turbocharger shaft, a thrust bearing (154) having a thrust bearing surface, and a bearing carrier (150). The bearing carrier includes a carrier body (158), a carrier body bore (160) extending axially through the carrier body and receiving the journal bearing therein, and a thrust bearing seat (164) on the exterior of the carrier body facing the turbine wheel. The thrust bearing seat has a complimentary shape to the thrust bearing surface of the thrust bearing, the thrust bearing disposed between the carrier body and the turbine wheel and engaging the thrust bearing seat. The bearing assembly further includes an anti-thrust bearing surface facing the compressor impeller, and an anti-thrust bearing (156) mounted to the anti-thrust bearing surface.

摘要： A fuel cell machine control system and method to provide extended range and operating times of a fuel cell machine (100) with a fuel cell (122) and battery (118) is disclosed. In some cases, the energy capacity of the battery (118) relative to the energy capacity of a fuel tank (126) may be in the range of about 0.2 to about 1.5. The range and/or the operating time of the fuel cell machine (100) is extended by using the fuel cell fuel to power the fuel cell machine (100) and continuing operating the fuel cell machine (100) after the fuel cell fuel is depleted using the battery (118). In some cases, the fuel cell machine (100) may autonomously be moved to a refueling/charging station (202) when the remaining charge in the battery (118) is within a threshold level of being depleted. Additionally, a total energy available to operate the fuel cell machine (100) may be determined and displayed.

摘要： An installation tool (100) for installing a seal (102) includes a shaft (106) and a seal-engaging component (128) coupled with the shaft (106). During an installation of the seal (102), the seal-engaging component (128) is adapted to couple with the seal (102). The seal-engaging component (128) includes a first surface (134) and a second surface (142). The seal-engaging component (128) also includes a first annular ring (138) extending from the first surface (134) and adapted to engage with the seal (102) for coupling the seal (102) with the seal-engaging component (128). The seal-engaging component (128) further includes a second annular ring (140) extending from the first surface (134). The installation tool (100) also includes a sliding hammer (126) adapted to slide along a length (L) of the shaft (106). During the installation of the seal (102), the sliding hammer (126) is adapted to apply a force to the seal-engaging component (128) for installing the seal (102) at a seal installation location.

摘要： A diagnostic system for a motor grader (10) with a blade (52), a drawbar member (46), and a center shift mounting member (30) associated with a drawbar-circle-moldboard (DCM) (20) includes actuators connecting the blade to the DCM and interconnecting other components of the motor grader. The actuators affect movement of the blade relative to the DCM and affect movement of the other interconnected components relative to each other. Sensors generate signals indicative of a current position of the blade and positions of the other components of the motor grader. An input device receives an operator input indicative of a selection of predefined, diagnostic positions that can be checked visually by the operator for confirmation of proper operation. A controller (66, 74) selectively actuates the actuators based on the selection of a diagnostic position and a signal indicative of the current position of the blade to move the blade and other components of the motor grader into the selected diagnostic position.

摘要： A marine propulsion control system (100), for use with a marine vessel (10), includes a port side engine (112) in electronic communication with a port side engine controller (108) and a starboard side engine (120) in electronic communication with a starboard side engine controller (110). A control station (18) includes a port lever (44) configured to control a throttle of the port side engine (112), a starboard lever (46) configured to control a throttle of the starboard side engine (120), and a user interface (48). A propulsion control processor (102) is in electronic communication with the port side engine controller (108), the starboard side engine controller (110), and the control station (18). The marine vessel (10) has a synchronized operating mode in which the propulsion control processor (102) transmits a throttle instruction to the port side engine controller (108) and the starboard side engine controller (110) pursuant to a throttle position of a master lever, the master lever corresponds to the first of the port lever (44) and starboard lever (46) to be actuated by an operator of the marine vessel (10) upon an activation of the synchronized operating mode.

摘要： A blade positioning system for a work machine (2) is disclosed. The system may have a blade control which has a blade position sensor, and the blade control may adjust a blade (1) of the work machine to a fixed position relative to a wheel (10, 11, 12, 13). The system may also have a steering control that has a wheel position sensor, and the steering control may steer the work machine. The controller may monitor the blade position sensor and the wheel position sensor to determine a present position of the blade and the wheel prior to the repositioning of the wheel, and adjust the blade position as the wheel is repositioned to maintain the fixed position of the blade relative to the wheel.

摘要： A work machine includes a frame, a traction system supporting the frame, an implement system supported by the frame, and a hydraulic system. The hydraulic system includes a hydraulic oil tank, a control circuit, an oil cooler, and a cooler bypass valve assembly. The cooler bypass valve assembly is connected to the control circuit by a control circuit return line, and includes an unloading valve configured to allow hydraulic oil to flow from the control circuit return line to the hydraulic oil tank if a pressure of hydraulic oil in the control circuit return line exceeds a first threshold, a backpressure valve configured to allow hydraulic oil to flow from the return line to the oil cooler through an oil cooler inlet line if a pressure of hydraulic in the oil control circuit return line exceeds a second threshold, and an orifice configured to limit the flow of hydraulic oil through the backpressure valve.

摘要： A transition track slider (400) has a hollow body (402) including a first side surface (404), a second side surface (404a), a bottom surface (406) at least partially interposed between the first side surface (404) and the second side surface (404a), and that also defines a cavity (408). A front surface (410) with a bullet nose configuration connects the first side surface (404) to the second side surface (404a), and to the bottom surface (406), while a rear surface (412) connects the first side surface (404) to the second side surface (404a), and to the bottom surface (406). A top surface (413) extends from the rear surface (412) toward the front surface (410).
