Embodiment Construction

[0021] refer to figure 1 , figure 2 , the bogie of the present invention is made up of the following parts: a frame composed of side beams, beams and end beams assembled and welded 1; axle and bridge components 2; short axle 3; advanced magnetic rail braking system 4; hydraulic brake Unit 5; secondary suspension system composition 6; secondary vertical vibration damping device 7; secondary lateral vibration damping device 8; elastic wheels with vibration and noise reduction effects 9; parallel double tie rod traction system 10. The frame composition is the basis for assembling other parts, and is one of the key components to realize the lowering of the car body floor; the short shaft 3 is assembled on the axle bridge composition 2, and is one of the key parts for changing the long shaft to a short shaft. The axle-bridge composition 2 is assembled with the elastic wheels 9 with vibration and noise reduction effects to form a wheel set structure. The elastic wheels 9 with vibr...

Abstract

The invention relates to an independent wheel trailer bogie for a 100% low floor light rail vehicle, which comprises a frame, an axle assembly, a primary spring, a secondary spring, four secondary vertical dampers, two secondary transverse dampers, a duplex pull rod traction mechanism and a hydraulic braking unit, wherein a side beam of the frame is in an outward projecting cantilever type; two stub axles are supported by bearing units and respectively connected with a resilient wheel; a vehicle axle comprises the two stub axles; two wheels at the same side of the bogie are fixed on a motor driving shaft; the motor is connected with two gear boxes; the four secondary vertical dampers are arranged at four corners of the frame; the secondary transverse damping devices are arranged at the two ends of the frame; and the parallel duplex pull rod traction system is arranged at the inside of the frame. The invention adopts the high-strength welded frame, the independent wheel axle assembly, the primary spring and the secondary spring with reasonable structures, the optimum secondary vertical dampers and secondary transverse dampers, the parallel duplex pull rod traction device with innertraction and the independent hydraulic braking unit, and truly realizes the 100% low floor of the vehicle body.

Description

technical field [0001] The invention relates to a bogie, in particular to a 100% low-floor light rail vehicle independent wheel trailer bogie. Background technique [0002] Compared with the trailer bogies of 70% low-floor vehicles and 100% low-floor trailer bogies, the low-floor area of ​​the upper body is relatively narrow, which brings inconvenience to passengers. In order to increase the range of low-floor areas, measures must be taken to reduce the height of high-floor areas over a larger area. At the same time, 100% trailer bogie is matched with 100% low-floor light rail vehicle independent wheel power bogie, which makes the vehicle bogie interchangeable and realizes modular design, which can greatly reduce maintenance costs, and at the same time, the car body chassis structure is also Unification can be achieved, which is irreplaceable for all current trailer bogies. Contents of the invention [0003] The technical problem to be solved by the present invention is ...
