Embodiment Construction

[0012] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0013] Such as figure 1 As shown, a three-axle power bogie based on a 100% low-floor tram is mainly composed of a rectangular frame 1, a wheel set device 2, a primary suspension 3, a secondary suspension 4, a power drive device 5, and a vertical damper 6. Composed of transverse damper 7, braking device 8, grounding device 9, traction rod 10, etc.

[0014] The rectangular frame 1 adopts a steel plate or casting assembly welding structure, and is a rectangular frame structure formed by welding two side beams, two cross beams and two connecting rods 1a. There are three sets of wheel set devices 2, which are arranged at intervals front and rear on the rectangular frame 1. Each set of wheel set devices 2 is mainly composed of wheel sets, axle boxes and axles, and two connecting rods 1a are arranged alternately with three axles. There are 12 primary suspensio...

Abstract

The invention discloses a three-axle power bogie based on a 100% low-floor tramcar. The three-axle power bogie comprises a rectangular framework, wheel set devices, primary suspensions, secondary suspensions, vertical dampers and transverse dampers. The three wheel set devices are arranged on the rectangular framework forwards and backwards at intervals, axles corresponding to the wheel set devices located on the front side and the rear side are power drive shafts, an axle corresponding to the wheel set device located in the middle is a non-power drive shaft, one side of each power drive shaft is provided with a power drive device, the other side of each power drive shaft is provided with a braking device and a grounding device, the two sides of the non-power drive shaft are provided with braking devices, and the two power drive devices are installed outside different side beams of the rectangular framework and arranged in a skew symmetry mode. The parts except for the power drive devices and the transverse dampers are symmetrically distributed according to the center point of the rectangular framework. Under the same load condition, compared with a two-axle bogie, the whole car acceleration is high, climbing capacity is high, adhesive force is large, and axle loads are effectively reduced.

Description

technical field [0001] The invention relates to a steering system of a tram, in particular to a three-axle power bogie based on a 100% low-floor tram. Background technique [0002] "Low floor" is a special term for light rail vehicles, which refers to light rail vehicles whose vehicle floor is less than 40 cm from the track surface. According to the percentage of the vehicle's low-floor area that can reach the passenger compartment area, low-floor vehicles are divided into many types. Among them, the most notable feature of "100% low-floor" modern trams is low cost, energy saving and environmental protection. Paved on the road, the vehicles stop on the ground, the construction cost of the modern tram operation system is only 1 / 4 to 1 / 3 of the subway, and the construction period is short and the pollution is less. The urban tram carrying system constructed by this kind of vehicle has higher passenger capacity, ride comfort and stability than buses, and also has the function ...
