Problems solved by technology

[0012] The purpose of the present invention is to solve the problem that the existing secondary suspension bogie is prone to severe axle box bearing wear, and propose a method to improve the track by changing the structure of the primary suspension system, secondary suspension system and drawbar system components of the vehicle bogie. A method for the overall performance of a vehicle secondary suspension bogie and a bogie system, the method and the bogie system effectively reduce axle bearing wear by changing the partial structures of the primary suspension system, secondary suspension system and drawbar system components of the vehicle bogie

Embodiment 1

[0069] attached figure 1 and 2 A specific embodiment of the present invention is provided; a bogie suspension vibration damping system includes a primary suspension system 2, a secondary suspension system 3 and a drawbar system 4 in a bogie 1; wherein, the primary suspension system The pivot arm node 5 changes the longitudinal stiffness, axial stiffness, torsional stiffness and The deflection stiffness makes the longitudinal stiffness and deflection stiffness of the pivot arm node 5 decrease, reducing the lateral load when the vehicle passes through the curve at high speed. At the same time, by increasing the axial stiffness, the torsional stiffness of the pivot arm node Stiffness is controlled at 11-13KN.mm -1 , the axial stiffness is controlled at 6-8KN.mm -1, so as to reduce the lateral load when the vehicle passes through the curve at high speed, and reduce the bearing wear inside the axle box; at the same time, by changing the structure of the primary vertical stop 6, ...

Embodiment 2

[0071] The structure of the second embodiment is basically the same as that of the first embodiment, except that the joint of the rotating arm is formed by combining two elastic rubber parts with symmetrical structures (as shown in the attached image 3 and 4 shown), including the left metal outer jacket 12 and the left metal inner jacket 11, the left rubber layer 13 is integrally vulcanized between the left metal outer jacket 12 and the left metal inner jacket 11, and the right metal outer jacket 14 and the right metal inner jacket 15, in The right rubber layer 16 is vulcanized as a whole between the right metal outer sleeve 14 and the right metal inner sleeve 15; the inner holes of the left metal inner sleeve 11 and the right metal inner sleeve 15 are respectively arranged as taper holes facing each other, that is, the big end of the taper hole is outside, and the taper hole The small heads of the inner back to back are close together; it is characterized in that the inner d...

Embodiment 3

[0080] Embodiment 3 has basically the same structure as Embodiment 1, except that the support ball joint device includes an upper half support base and a lower half support base, the upper half support base is fixedly connected to the vehicle body frame, and the support ball joint is arranged on Between the upper half support seat and the lower half support seat, the connecting bolts are screwed into the upper half support seat through the lower half support seat, the lower half cover and the upper half cover in sequence, so as to connect and fix the supporting spherical hinge device on the on the body frame.

[0081] The two ends of the rubber layer of the inner sleeve of the bogie jib node are each dug inward with a circle of annular grooves; among them, the groove depth dimension H3 of the small diameter end is controlled at 15~30mm; the groove depth dimension H4 of the large diameter end It is controlled at 10~20mm, and the radial stiffness of the bogie is reduced and the ...

Abstract

A method for improving the overall performance of a rail vehicle bogie and a suspension damping system. The system stiffness of the jib node is adjusted by changing and adjusting the jib node parameters, so that the longitudinal stiffness and deflection stiffness of the jib node are reduced, and at the same time, by increasing the axial stiffness , to avoid the decrease of the torsional stiffness of the pivot arm node; also reduce the vertical stiffness of the primary suspension by changing the structure of the vertical stop; prevent the axial movement of the anti-roll torsion bar by changing the structure of the anti-roll torsion bar supporting the spherical joint; Adjust the structure of the traction ball joint of the traction bar system to control the nonlinear stiffness of the traction ball joint, so that the traction ball joint has a moderate transitional nonlinear stiffness; through the change of the pivot arm node and the vertical stop of the primary suspension system, the secondary suspension The system changes the structure of the anti-roll torsion bar support ball joint and the structure of the traction ball joint to adjust the longitudinal stiffness, axial stiffness, torsional stiffness and deflection stiffness of the entire bogie, and further improve the overall performance of the bogie.

Description

technical field [0001] The invention relates to a method and device for adjusting the performance of locomotive components, in particular to a method for improving the secondary suspension bogie of rail vehicles by changing the structure of the primary suspension system, secondary suspension system and drawbar system components of the vehicle bogie An overall performance method and bogie system for improving the overall performance of a rail vehicle bogie. The invention belongs to the technical field of locomotive key component manufacturing. Background technique: [0002] The vehicle bogie system is one of the most important components in the rail vehicle structure, and various parameters of the bogie also directly determine the stability of the vehicle and the ride comfort of the vehicle. The vehicle bogie is an independent component assembled from parts and devices of the running part of the rolling stock. It plays the role of supporting the car body, steering and brakin...
