Description
Technical field
The present invention relates to magnetic suspension train technical field, particularly relate to the mid-suspension rack of frameless formula traction linear electric motors and magnetic suspension train.
Background technology
Magnetic suspension train and the key distinction of common wheel track vehicle are that the generation mechanism of tractive force, guidance force and vehicle support power is different.Non-contact electromagnetic power between magnetic suspension train vehicle mounted electric magnet and inverted U track, substitutes between wheel track vehicle wheel and track by the bearing force of contact generation and guidance force; With linear electric motor primary and secondary between non-contact electromagnetic tractive force substitute adhesion between wheel track.The tractive force that linear electric motors produce does not limit by wheel track adhesion, and its hill climbing ability, curve negotiation ability are far above traditional wheel track vehicle.
In recent years, for solving the layout of large-scale traction linear electric motors in magnetic suspension train traveling unit and installation question, Chinese patent literature CN102963266A discloses and a kind ofly draws the mid-magnetic suspension train traveling unit of linear electric motors, and by two, independently suspending module, traction linear electric motors, two crossbeams, four cover crossbeam ball pivot Straight Combination bearings, two motor suspension rods and a set of anti-roll decoupling mechanisms form.Traction linear electric motors are arranged between left and right suspending module to reduce the limiting factor of motor size, be lifted on the middle part of front and back ends crossbeam by forward and backward motor suspension rod, two crossbeams are arranged on left and right suspending module by four cover crossbeam ball pivot Straight Combination bearings.Anti-roll decoupling mechanism is made up of two principal arms, the anti-roll beam of two panels, two anti-roll suspension rods and two cover principal arm ball pivot Straight Combination bearings, be arranged on the midsection of suspension rack along vertical track direction, suspending module can be retrained and move around sidewindering of track and transmit motor traction force.
