摘要： Quick-load retail merchandising product pusher systems and methods dispense retail products, wherein the systems and methods have a fixed portion having a front end, a rear end located opposite with respect to the front end of the fixed portion, a top side and a bottom side located opposite with respect to the top side of the fixed portion. Further, the systems and methods have a movable track movably connected to the top side of the fixed portion, wherein the movable track has a front end, a rear end located opposite with respect to the front end of the movable track, a top side and a bottom side located opposite with respect to the top side of the movable track. Still further, the systems and methods have a pusher paddle configured to move one or more retail product forward away from the rear side of the movable track and front retainer teeth connecting the fixed portion and the movable track, wherein the front retainer teeth are provided on the top side and at the front end of the fixed portion and extend outwardly with respect to the top side of the fixed portion. The movable track is movable to a closed position or to an extended position, wherein, when the movable track is moved to the extended position, forward movement of the pusher paddle is restricted by the front retainer teeth.

摘要： A bogie for a high-speed railway vehicle includes a wheel set, an axle box, a primary spring suspension device, a frame, a secondary spring suspension device and a foundation braking device. A wheel of the wheel set has an LMA wheel tread. The foundation braking device is mounted by a three-point hitch structure. The axle box is a structure which is separatable in a vertical direction, and an off-line safety protecting device is mounted at a lower portion of the axle box. A traction rod of the secondary spring suspension device is a single traction rod. A center pin is provided with an integral hoisting device. Two anti-yaw dampers, as a group, are arranged at either side of the secondary spring suspension device, and the two anti-yaw dampers have the same damping coefficient.

摘要： The present invention relates to a running gear of a rail vehicle defining a longitudinal direction, a transverse direction and a height direction, the running gear comprising a first wheel unit (103.1) and a second wheel unit (103.2) defining a wheel unit axle distance, a running gear frame (104) supported on the first wheel unit (103.1) and the second wheel unit (103.2), and a first drive unit (107.1) driving the first wheel unit (103.1). The first drive unit (107.1) comprises a first reaction moment support unit (110) connected to the running gear frame (104) at a first support location to balance a drive moment exerted onto the first wheel unit (103.1) by the first drive unit (107.1). The first support location, in the transverse direction, is laterally offset from a center of the running gear frame (104). The first support location, in the longitudinal direction, is located at a first support location distance from a first wheel unit axle of the first wheel unit (103.1), which is at least 35% of the wheel unit axle distance.

摘要： The present invention relates to a flexible direct-drive bogie and implements a flexible frame by using a flexible cross beam, so as to make it easy for left and right side-frames to nod relatively to adapt to a larger twist of a track. As the frame is flexible, a primary suspension of the present invention is simplified to a thin layer of rubber pad, so that the production cost is reduced. Flexible drive devices enable flexible suspension of a permanent magnetic motor, and at the same time, can transmit torque, improve transmission efficiency, and reduce a weight of a transmission mechanism.

摘要： A bogie for locomotives is provided. Two wheelsets, each including a drive unit, are disposed in a bogie frame, wherein the wheelsets each include a wheelset shaft and two wheels. The drive unit comprises a motor unit and a transmission disposed to ride on an axle, and each motor unit is suspended at three points, namely at a main pivot point on the transverse beam of the bogie frame and two mounting points on a head beam of the bogie frame. Further, the motor unit is transversally elastically suspended; the transmission is mounted pivotally about the wheelset shaft but not displaceable along the wheelset shaft. The transmission is further connected to the motor unit by a transmission torque support, and the drive unit comprises a clutch by which the motor unit has a driving connection to the wheelset by the transmission.
