Definitions

  • the present invention relates to the field of railway trains, and in particular relates to a suspension mechanism for mounting a motor of a railway train. Besides, the present invention further relates to a railway train having the suspension mechanism for mounting the motor.
  • a multiple-unit train is one type of railway trains, which includes at least two locomotives or powered carriages and multiple non-powered carriages.
  • the multiple-unit train is developed from double heading locomotive, but is different from the traditional double heading locomotive.
  • Double heading locomotive with an increasing number of locomotives rather than changing the fact of the carriage being a trailer, is generally used for freight trains and mainly solves a problem of insufficient tractive force.
  • the multiple-unit train is almost used for passenger trains only, and mainly solves problems of insufficient acceleration and restricted maximum speed.
  • Driving devices of the passenger train may be arranged in multiple passenger carriages respectively, so that these carriages are powered, while a heading locomotive of the passenger train may become a trailer which only has a console but without the driving force.
  • each carriage is equipped with a driving device, and a heading locomotive may blend into the carriage, or there is no heading locomotive, and the train is entirely controlled by a railway system.
  • This multiple-unit train is mainly used in some urban railway transport trains such as maglev trains, APM (Automated People Mover) trains and ultra-high speed test trains and so on.
  • the multiple-unit train generally includes two locomotives, multiple powered carriages and non-powered carriages.
  • the driving device in the heading locomotive is removed, and only control equipment of the train is kept.
  • a motor is required to be suspended from a bogie. Since the traction motor is movable with respect to a bogie frame in a direction parallel to a main shaft of the motor, a position-limiting device is required to be provided between the motor and the bogie frame in order to avoid an excessive range of motion. Meanwhile, in order to prevent the motor from falling off in a case of suspension failure, a safety mechanism for preventing the motor from falling off is required to be provided on the motor or the frame.
  • US 4,228,739 A discloses a system for suspending the traction motor and gear box of a parallel drive arrangement in a railway truck or the like in which the gear box and traction motor shafts are flexibly coupled together to accommodate relative movement between the two shafts. In addition, an arrangement is provided by which the mounting of the motor on the railway truck accommodates lateral displacement while the coupling between the traction motor housing and the gear box accommodates angular and offset misalignment of the coupled shafts.
  • the most common manner for position-limiting at present is to provide a rigid stop or a single elastic stop
  • the most common manner for preventing the motor from falling off is to provide a joist on the motor, or to provide a safety hook between the motor and the frame.
  • the suspension and position-limitation of the motor cannot be realized at the same time through the above manners, resulting in a complex structure and a large occupied space of the equipment, which is not beneficial to the installation and maintenance.
  • a technical problem to be addressed by those skilled in the art is to provide a suspension mechanism for mounting the motor which can realize the suspension and position-limitation of the motor, simplify the structure, save space, and facilitate the installation and maintenance.
  • a suspension mechanism for mounting the motor of a railway train is provided according to claim 1.
  • the connector includes two connecting plates arranged in parallel, a front side edge of the connecting plate is connected to the bogie frame, two opposite positioning holes are provided in the two connecting plates, respectively, and two ends of the safety pin are mounted in the two positioning holes, respectively.
  • Each connecting plate is vertically arranged and substantially P-shaped, a right angle portion at a side, facing the motor, of each connecting plate is smoothly transitioned to form a cambered edge, and the safety pin is arranged at a head portion, having a relatively large width, of each connecting plate.
  • an end, close to the safety pin, of the cantilever is provided with a connecting hole horizontally penetrating an end portion of the cantilever, a penetration direction of the connecting hole is perpendicular to an extension direction of the cantilever, the connecting hole is sleeved on the safety pin, and in clearance fit with the safety pin.
  • the cantilever is sleeved on the safety pin; in a radial direction perpendicular to the length direction of the safety pin, the cantilever includes an inner ring and an outer ring, the inner ring is in clearance fit with the safety pin through the connecting hole, and the outer ring is connected to the motor.
  • the suspension mechanism for mounting the motor includes two elastic position-limiting pieces sleeved on two ends of the safety pin, respectively, end portions of the two elastic position-limiting pieces are fixedly connected to inner side plate surfaces of the two connecting plates respectively, and the end portion of the cantilever is located between the two elastic position-limiting pieces and is spaced apart from the two elastic position-limiting pieces.
  • each of the two elastic position-limiting pieces includes a mounting seat fixedly connected to the inner side plate surface of the connecting plate and a spring arranged in the mounting seat and sleeved on the safety pin, and a bottom surface of the mounting seat is provided with a through hole for the safety pin to penetrate.
  • an end away from the mounting seat of the spring is provided with an end cover, and the end cover is provided with a through hole for the safety pin to penetrate.
  • the mounting seat is connected to the connecting plate by bolts.
  • the end cover is specifically a rubber cover.
  • a railway train is provided according to claim 9.
  • the suspension mechanism for mounting the motor of a railway train is provided according to the present invention which is defined by the technical features set forth in claim
  • the connector is connected to the bogie frame, the cantilever is connected to the motor, and the cantilever and the connector are connected by the safety pin, so that the motor and the bogie frame are connected.
  • the suspension of the motor can be realized through the cantilever, and the position limitation of the motor can be realized through the elastic position-limiting piece on the safety pin, that is, when realizing the position limitation of the motor, multiple safeguards are provided for the suspension of the motor, and the suspension mechanism has a simple and compact overall structure, saves space, facilitates installation and is beneficial to manufacture, operation and maintenance.
  • a railway train including the suspension mechanism for mounting the motor is further provided according to the present invention. Since the suspension mechanism for mounting the motor has the above technical effects, the railway train having the suspension mechanism for mounting the motor also has the same technical effects, which will not be described in detail herein.
  • Figure 1 is a schematic view showing the structure of a specific embodiment of a suspension mechanism for mounting a motor provided according to the present invention
  • Figure 2 is a sectional schematic view showing a specific embodiment of the suspension mechanism for mounting the motor provided according to the present invention.
  • a suspension mechanism for mounting the motor of a railway train including a connector for connecting to a bogie frame, a safety pin 2 mounted on the connector and arranged horizontally, and a cantilever 3.
