Problems solved by technology

However, in order to ensure the good curve passing performance of the vehicle, it is usually required that the shaking head stiffness between the wheelsets be small, but because it is related to the shear stiffness, the shear stiffness is also reduced accordingly, and the decrease of the shear stiffness is not conducive to the stability of the vehicle. Smooth running in a straight line

Embodiment 1

[0017] figure 1 It is shown that a specific embodiment of the present invention is: a railway vehicle wheel pair diagonal tie rod connection device, in which the tie rod seats are arranged on the axle boxes 2 on different sides of the front and rear wheel pairs 11 and 12 of the bogie 3. The two ends of the diagonal tie rod 4 are hinged to the tie rod base 3 through hinge parts. The articulated parts that are hinged at the two ends of the tie rod seat 3 and the diagonal tie rod 4 are joint bearings. The shape of the diagonal tie rod 4 is a shape that can avoid other parts in the bogie frame, such as figure 1 The zigzag in . The structure of this example is suitable for the passenger car or locomotive that axle box is installed on the wheelset.

Embodiment 2

[0019] This example is basically the same as the first example, the only difference is that the tie rod seat 3 is set on the bearing saddles on different sides of the front and rear wheel pairs 11, 12 of the bogie. The articulated parts that are hinged at the two ends of the tie rod seat 3 and the diagonal tie rod 4 are rubber joints. The structure of this example is suitable for the freight car that bearing saddle is installed on the wheelset.

Abstract

The invention discloses a diagonal draw bar connection device for railway vehicle wheel pairs, which is characterized in that axle boxes (2) or bearing saddle at different sides on front and rear wheel pairs (11, 12) are provided with draw bar bases (3), and both ends of a diagonal draw bar (4) are hinged on the draw bar bases (3) through hinging components. The device can ensure that the decoupling is performed on the shearing rigidity and the headshaking rigidity between two wheel pairs of the same steering frame, and remarkably improve the shearing rigidity under the condition of not affecting the headshaking rigidity, thereby improving the stability of the operation of vehicles on the basis of not affecting the curve passing performance of the vehicles.

Description

technical field [0001] The invention relates to an arrangement for a railway vehicle bogie. Background technique [0002] The wheel sets of existing railway vehicles are positioned relative to the frame through elastic suspension components. Mainline freight vehicle bogies are generally two-axle bogies (that is, one frame corresponds to two wheel sets). For freight cars, the frame of the bogie is directly supported on the saddle, and the saddle is supported on the wheel axle bearing Above, through the contact friction between the frame of the bogie and the bearing saddle, the lateral and longitudinal movement of the wheel set and the oscillating movement of the rotation along the vertical axis are restricted. For passenger cars and locomotives, the frame of the bogie is supported on the axle box of the wheel set through the axle box spring suspension device, and realizes the lateral and longitudinal positioning between the bogie and the wheel set. When one of the wheel pai...
