摘要： A framework (10) comprises a longitudinal beam (12), a crossbeam and a mounting base; a groove (13) is provided on the longitudinal beam (12), and the opening of the groove (13) faces toward the outer side of the framework (10); a current-receiving apparatus case (1) is connected to the framework (10) by means of the mounting base (9), and the mounting base (9) is fixed inside the groove (13) by means of welding or fasteners.A current-receiving apparatus is also related to, which comprises a current-receiving apparatus case (1), rotary arms (2) and collector shoes (3); the upper end of the rotary arm (2) is hinged to the current-receiving apparatus case (1); the collector shoe (3) is connected to the lower end of the rotary arm (2); the current-receiving apparatus case (1) has a space for the rotary arm (2) to tilt; the rotary arm (2) can drive the collector shoe (3) to rotate about the hinged point until same comes into contact with a side surface of a third rail (4), or rotate until same comes into contact with a bottom surface of the third rail (4), so as to achieve a current-receiving means that integrates the bottom surface and side surface with the same bogie, and allow same to adapt to changes in the current-receiving means due to limited space of a railway bridge, thus ensuring the normal operation of vehicles.

摘要： A light rail vehicle bogie comprises a frame (1), the frame (1) comprises side beams (11) and a cross beam (12), a middle part of the side beam (11) is recessed, a top of the cross beam (12) is provided with a bolster (2), the cross beam (12) is composed of two tube bodies (121), both ends of each tube body (121) are provided with connecting seats (8), and the both ends of the tube body (121) are fixedly connected to the side beams (11) through the connecting seats (8); cantilever seats (16) extending inward are provided on two axle boxes of the light rail vehicle bogie, and a magnetic rail brake (9) provided right below the tube bodies (121) is suspended on the two cantilever seats (16); a vertical guide rod (17) is arranged at the top of the magnetic rail brake (9), two limit seats (10) right above two ends of the magnetic rail brake (9) is mounted on one side of each connecting seat (8), and the limit seat (10) is provided with a guide hole (18) for inserting the vertical guide rod (17). The bogie realizes low-position traction of a light rail vehicle, and the space of the cross beam is optimized.
