摘要:
A platform sensing and control system including a wireless sensor (10, 12) for sensing at least the presence of a platform (26) opposite a door (32) of a railcar and providing an output indication of at least a platform presence in response thereto, and a door control controller (14) operative in response to the output indication of at least platform (26) presence for enduring that normally a door (32) is not opened other than when a platform (26) is located opposite such door (32).
摘要:
The floor of a passenger cabin in a railway car is mounted on a base plate 23 of an underframe 11 via plural common joists 33, 34. The vibration of the truck is transmitted via a center pin 27, a bolster 25, center sills, a base plate 23, and common joists 33, 34 to the floor 31, thereby vibrating the floor. Out of the common joists 33 and 34, the common joists 34 that are positioned near the width-direction-center of the car body do not extend beyond the center sill 25 toward the longitudinal end of the car body. This arrangement reduces the vibration of the floor 31 positioned at the longitudinal end portion of the car body.
摘要:
A powered operator assembly for moving an object along a linear axis and particularly for moving doors in a mass transit vehicle utilizing a helical drive member for moving and supporting an attached door panel. The helical drive engages a drive nut that is connected to one of the two door panel hanger assemblies. Each door panel hanger assembly is attached to the door panel and includes at least two rollers which engage the outer surface of a helical drive for motion along the drive axis. One end of such helical drive is connected to an electric prime mover with such prime mover mounted to a stationary bracket mounted to the door opening structure. The second end of the helical drive engages a bearing mounted to a stationary bracket mounted to the door opening structure.
