Straddle type monorail traction mechanism with auxiliary steering device and its bogie

Abstract

The invention provides a straddle type monorail traction mechanism with an auxiliary steering device and its bogie. The straddle-type monorail traction mechanism includes a first upper draw bar, a second upper draw bar, a transverse connecting rod, an auxiliary steering device, a first upper crank, and a second upper crank; both the first upper crank and the second upper crank include a rotation center Shaft and three connecting arms integrally arranged on the outside of the central axis of rotation; the three connecting arms are the first connecting arm, the second connecting arm, and the third connecting arm, and the first connecting arm, the second connecting arm, and the third connecting arm The extension lines can all pass through the axis of the central axis of rotation, and the first connecting arm and the third connecting arm are respectively arranged on two sides of the second connecting arm. The three connecting parts (drawing rod, transverse connecting rod, auxiliary steering device) connected to the crank are in the same horizontal plane, therefore, the crank of the present invention only bears the action of torque, the force is simple, the structure design is simple, and it can be forged or machined. Processed parts, good manufacturing process, high reliability.

Description

technical field [0001] The invention belongs to the field of straddle-type monorail traffic vehicles, and in particular relates to a straddle-type monorail traction mechanism and a bogie. Background technique [0002] Straddle-type monorail bogies are known in the art. There is a monorail bogie supporting the car body at the front and rear of the monorail vehicle. The monorail bogie is used to support the car body and move along the direction of the track beam. The monorail bogie has Traveling wheels that run along the upper surface of the track and guide wheels that run along the side of the track and provide lateral support for the monorail. [0003] A common problem with such monorail bogies is that the load on some of the guide wheels of the monorail bogie increases significantly when the monorail bogie travels on curved sections of the track. In most cases, a monorail bogie has four guide wheels that run along the side of the monorail track: the outer inner guide, the ...

Problems solved by technology

According to the disclosure content of this patent document, it can be seen that in the monorail bogie assembly, the three connecting parts (traction rod, auxiliary steering cylinder, and transverse connecting rod) connected to the bell crank mechanism are not on the same level, and the bell crank mechanism not only bears The torque applied by the three connecting parts also bears the additional bending moment caused by the fact that the three are not at the same level, so the bell crank mechanism is subjected to complex forces, and the casting structure of the bell crank mechanism is complex, which is prone to casting defects
