    摘要: The present invention discloses an underneath type railway freight car bogie wheelset radial device. The underneath type railway freight car bogie wheelset radial device consists of front and rear subframes and two cross-arranged connecting rods that are pinned by round pin connectors; the subframe is a combination structure of the adapter and the lateral arm; the connecting rods are arranged under the bolster to form the underneath bogie wheelset radial structure; the height of the central plane of the connecting rod is lower than the height of the central plane of the subframe adapter surface; The adapter consists of an adapter surface forming an arc-shaped adapter structure and an adapter connecting arm integrated with the adapter surface structure and vertically arranged at one end of the adapter surface; the subframes are fixed to the adapter by the rivet assembly. The radial device of the present invention can better adapt to the traditional lever brakes and integrated brakes, effectively improving the versatility of the bogie and facilitating technical transformation and upgrade of the bogie; the radial device can be assembled independently, and the assembly process of the bogie is simple and convenient; the wheelset radial device and other parts of the bogie can be directly separated by removing the retaining key, without affecting the structure of other parts, effectively reducing the difficulty of maintenance.

    摘要: The present invention discloses a railway self-generating express freight car bogie. The railway self-generating express freight car bogie consists of wheel-axle assembly, frame, journal box suspension device, bolster, foundation brake, side bearing, empty/load auto-adjustment equipment, central suspension device, longitudinal traction device, vertical damper and lateral damper. An axle-end generator is connected at the outer end of an axle of the wheel-axle assembly, the rotor part of the axle-end generator is connected to the end bearing of the wheel-axle assembly by the axle-end bolts, and the stator part is connected to the mount of the journal box suspension devices. The present invention can provide electrical energy input for freight vehicles. The bogie is designed according to the zero-wear concept, and a large number of rubber components and hydraulic dampers are used to improve the lateral stability, linear stability and curve passing performance of the car, so that the bogie is highly adaptable to railway lines, and can meet the operating requirements within 160km/h and reduce the workload of bogie operation and maintenance.

    摘要: The present invention discloses a sealed bottom door of a hopper car, including a bottom door frame and a bottom door, and further including a slideway. The bottom door is slidably disposed on the slideway, the bottom door frame is in contact fit with the bottom door, a support portion on the slideway has a support height gradually increasing along a closing direction, and/or a lifting portion of the bottom door has a lifting height gradually increasing along an opening direction. According to the present invention, automatic change in a gap between the bottom door and the bottom door frame when the bottom door is opened and closed is achieved through contact combination of three rollers, a bottom door plate and a sealing adjustment plate, so as to effectively improve sealing of the bottom door, resolve inertia problems of rain and snow infiltration and cargo leakage caused by structural gaps in bottom doors of existing hopper cars, and reduce manufacturing difficulties and maintenance cost.

    摘要: The present invention discloses a large-volume grain hopper car suitable for a low-loading position hopper bin. The grain hopper car includes a car body; a loading opening of the car body is provided with a top cover opening and closing mechanism, the top cover opening and closing mechanism includes a top cover and a transmission shaft, the transmission shaft is located inside the car body, the transmission shaft is connected to a top cover driving mechanism, the transmission shaft is hinged to a crank throw, and the crank throw is hinged to the top cover. The beneficial effects of the present invention are as follows: According to the grain hopper car, the arrangement of the top cover opening and closing mechanism is innovated in order to improve the volume of the car, and the transmission shaft, which is conventionally disposed on the car roof for opening and closing the top cover, is disposed in the internal space of the car body in such a way that the upper space of the car roof is utilized to the maximum extent, and the distance between the car roof and the upper limit is closest, so that the volume of the car is improved under the condition of the same car length, and the loading capacity of the whole train is improved; besides, by translating or sliding the top cover, the occupancy of the upper space in the opening process of the top cover is decreased, thus the grain hopper car is suitable for a station yard with the low-loading position hopper bin condition.

    摘要: The present invention discloses a translation type top cover of a grain hopper car. The top cover includes a cover body located at a loading opening of a car body, wherein one side of the cover body is hinged to a crank throw, the crank throw is connected to a transmission shaft rotating in the car body, the other side of the cover body is hinged to a connecting lever, the connecting lever is hinged to the car body, and the transmission shaft is connected to a driving mechanism. The beneficial effects of the present invention are as follows: the top cover convenient to operate is provided to solve the problems of low working efficiency and operation with poor safety in the prior art; when the top cover is in the closed state, a self-locking air cylinder guarantees the vertical locking capacity of the top cover, a longitudinal stopping block guarantees the longitudinal locking capacity of the top cover, and a locking base and a locking rod guarantee the transverse locking capacity of the top cover; and a four-connecting-rod mechanism is formed among the car body, the crank throw, the connecting lever and the cover body to achieve translational opening and closing of the cover body and reduce space required.

    摘要: A radial steering rack for secondary framework comprises wheelsets, lateral racks, a swing bolster, a wheelset radial device and a braking device. Bearing saddles (41) forming the wheelset radial device are fixedly connected with the secondary framework (42) via pulling rivets (11), and each group of the bearing saddles (41) is bilaterally symmetrical in structure with a symmetry plane (A). The secondary framework (42) comprises an arm part (51) and an end part (52); a connection hole (61) is arranged on the end part (52); transverse positioning bosses (73) are arranged on the bearing saddles (41); and an arc groove (75) and symmetrical connection holes (71) are arranged on a connection base (72). The wheelset radial device is a split casting structure, therefore the dead weight of the assembled wheelset radial device is greatly reduced, the unstrung weight of the steering rack is reduced, the action force of the wheel and the track is effectively reduced, the dynamics properties of the vehicle and the stress state of the secondary framework are improved, and the fatigue life of the secondary framework is prolonged. The bearing saddles use the same standard structure, hence, the more precise design and machining can be realized, and the cost is reduced, and meanwhile, the maintenance technique of the secondary framework is improved, and the maintenance cost is reduced.
