Abstract

The invention discloses a three-axle bogie, which relates to the technical field of railway engineering vehicles and comprises a framework, three wheel sets and a traction mechanism; the traction mechanism is arranged on the framework, and the three wheel sets are connected with the bottom of the framework through axle box bodies respectively; the framework is a rectangular framework defined by two end beams and two side beams, two cross beams are arranged between the two side beams at a distance, and a center plate beam is connected between the two cross beams; guide frames are arranged at the bottoms of the side beams and are elastically connected with the corresponding axle box bodies; side bearings are arranged at the tops of the side beams; the axle box bodies are connected with the corresponding wheel sets through axle box bearings and bearing saddles; the traction mechanism comprises a lower center plate, an upper center plate and a center pin; the lower center plate is mountedon the center plate beam; the upper center plate is mounted on the lower center plate through a center plate abrasion pad; the center pin is installed on the center plate beam, the end of the center pin sequentially penetrates through the lower center plate, the center plate abrasion pad and the upper center plate, and the upper center plate and the lower center plate are prevented from being disengaged in the operation process.

Description

technical field [0001] The invention relates to the technical field of railway engineering vehicles, in particular to a three-axle bogie. Background technique [0002] The bogies for railway engineering vehicles in the prior art are mainly two-axle bogies. When the vehicle's own weight or carrying capacity is large, the axle load of the two-axle bogies cannot meet the requirements of the vehicle's own weight and carrying capacity. SUMMARY OF THE INVENTION [0003] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide a three-axle bogie, which can be used for large dead-weight and large-load engineering vehicles. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a three-axle bogie, including a frame, three wheel sets and a traction mechanism; the traction mechanism is arranged on the frame, and the three wheel pairs are connected to the frame through the axle box respecti...
