Embodiment Construction

[0058] A track engineering car bogie, as shown in Figure 1, figure 2 and image 3 As shown, it includes ATP induction coil device 1, rim lubricating device 2, primary suspension device 3, frame 4, third rail current receiver 5, secondary suspension device 6, bogie air pipeline 7, and foundation braking device 8 , traction device 9, wheelset drive system 10. like image 3 As shown, the traction motor of the traction device 9 adopts a full suspension mode, and is rigidly suspended on the frame 4 by bolts at four points.

[0059] like Figure 4 As shown, the primary suspension device is arranged between the frame 4 and the axle box, and the wheelset is positioned by a rotating arm. One end of the axle box is connected with the frame 4 through a rubber joint, and a metal coil spring group 17 and a series of rubber pads 18 are installed at the other end. In order to attenuate a series of vertical vibrations, a series of vertical oil pressure shock absorbers 21 are also provide...

Abstract

The invention discloses a rail engineering truck steering frame belonging to the field of rail vehicle steering frames. Aiming at the defects of large turning radius and incapability of meeting the low-speed operation working conditions of the traditional rail engineering truck, the steering frame comprises an H-type frame, ATP (Array Transform Processor) induction coil devices arranged at end parts of two lateral beams of the frame, rim lubricating devices arranged at two ends of a locomotive, a primary suspension device, a secondary suspension device, a third rail current collector arranged at the middles of the lateral beams of the frame, a basic brake device transversely arranged on the lateral beams of the frame, and a traction device connected with the frame by adopting a full-suspension manner; and a gear box is hung on a cross beam of the frame and is internally provided with two stages of gear transmissions with total transmission ratio of (7.63-10.03):1. The rail engineering truck steering frame has the highest operation speed of 90km / h, the continuous speed of about 18km / h and the lowest operation speed of below 5km / h and has the advantages of small turning radius, high low limit, simpler structure, convenience for maintenance and high reliability.

Description

technical field [0001] The invention relates to the field of rail vehicle bogies, in particular to the field of manufacturing rail engineering vehicle bogies. Background technique [0002] Rail engineering vehicles are indispensable rail engineering transportation tools in the initial stage of construction, operation preparation, trial operation, and formal operation of the main railway line and subway. Due to terrain constraints, subway lines often have many curves, small curve radius, and large slope (the maximum slope is 38‰). [0003] In order to pursue good running quality, the existing passenger locomotive bogies mostly use high-round spiral steel springs with large deflection for the secondary suspension, three-point rigid or elastic suspension for the motor, and wheel-set hollow shafts for the wheel-set drive system. The transmission and the axle box adopt the double-axle box pull rod positioning method, and the frame adopts the "mesh"-shaped structure or the "day"-...
