Problems solved by technology

However, when the gap A is smaller than the required value, the frame may touch a vertical stop when the vehicle is full, which will greatly reduce the vibration and noise reduction effect of the vehicle in the vertical direction, thus affecting the comfort of passengers. sex

Embodiment 1

[0026]Embodiment 1: A rigid spacer (4) with a thickness of Δh is added between the contact surface of the bogie axle box (3) and the chevron spring (2).

[0027]Such asimage 3 As shown, a rigid spacer (4) with a thickness of Δh can be added between the contact surface of the bogie axle box (3) and the chevron spring (2). Through the above theoretical expression, the frame (1) and The gap between the top surfaces of the herringbone spring (2) produces an increase of ΔH. In this embodiment, the rigid spacer (4) is preferably a rigid gasket, which is laid between the contact surface of the bogie axle box (3) and the chevron spring (2) and covers the chevron spring (2) and The entire contact surface of the bogie axle box (3) makes the gasket in a V shape, so that the contact surface of the gasket and the herringbone spring (2) fits better. In this embodiment, the V-shaped gasket includes a pair, which are respectively arranged between the contact surfaces of the chevron spring (2) and the ...

Embodiment 2

[0029]The second embodiment: the second rigid spacer (5) with a thickness of ΔH is added between the contact surface of the frame (1) and the chevron spring (2).

[0030]According to the theoretical relationship between the thickness increase Δh of the herringbone spring (2) and the gap increase ΔH between the frame (1) and the top surface of the herringbone spring (2), it is also possible to directly compare the frame (1) and the herringbone spring (2) Correct the gap between them. Specific asFigure 4 As shown, a second rigid spacer (5) with a thickness of ΔH is added between the contact surface of the frame (1) and the chevron spring (2). The material of the second rigid spacer (5) can be the same as that of the first embodiment. In addition, the second rigid spacer (5) covers the entire contact surface of the herringbone spring (2) and the frame (1), so that the second rigid spacer (5) is in a V shape. Rigid spacer one (4), in addition to the integrated V-shaped gasket, can also be ...

Embodiment 3

[0032]Embodiment 3: Add a rigid spacer (4) with a thickness of Δh between the contact surface of the bogie axle box (3) and the chevron spring (2), and the frame (1) and the chevron spring (2) Two rigid spacers (5) with a thickness of ΔH are added between the contact surfaces.

[0033]The third embodiment combines the setting methods of the first and second embodiments. This embodiment can ensure the expected clearance correction amount ΔH while minimizing the impact on the overall rigidity of the entire axle box frame. In the specific implementation, a V-shaped gasket with a thickness of Δh can be laid between the contact surface of the bogie axle box (3) and the chevron spring (2); a flat gasket with a thickness of ΔH is laid on the frame (1) Between the contact surface with the herringbone spring (2). The V-shaped gasket is combined with the flat gasket to form an L-shaped gasket, which ensures that the contact surface of the herringbone spring (2) and the gasket will not move relat...

Abstract

The invention relates to a bogie axle box gap correction method and device. The bogie axle box gap correction device comprises a first rigid spacer with the thickness of delta h, the first rigid spacer is located between the contact faces of a bogie axle box and a herringbone spring, and when the increment of the gap between a framework and the top face of the herringbone spring is delta H, an expression sin alpha = delta h / delta H is satisfied between the thickness delta h of the rigid spacer I and the inclination angle alpha of the herringbone spring. According to the method, the rigid spacer is added between the contact surfaces of the bogie axle box and the herringbone spring and / or the contact surfaces of the framework and the herringbone spring, so that the gap between the frameworkand the top surface of the herringbone spring is corrected, and the influence on the rigidity between the whole herringbone spring and the framework is small; and relative movement between the rigid spacer and the herringbone spring is avoided, so that the gap correction basically conforms to an expected value.

Description

Technical field[0001]The invention relates to the field of locomotive bogies, in particular to a method and device for correcting the clearance of the axle box of the bogie.Background technique[0002]The bottom of the locomotive bogie includes a herringbone spring, a frame and an axle box. The herringbone spring connects the frame and the axle box. The herringbone spring is made of metal plate and rubber vulcanized. The rubber will be permanently deformed under the influence of load, environment and other factors. , Which will cause the working height of the herringbone spring to become shorter. After the herringbone spring was repaired on a certain line of Guangzhou Metro, the clearance of axle box A was smaller than the required value. Such asfigure 1 As shown, when the gap A is within the normal range, the frame will only touch a series of vertical stops when the vehicle is fully loaded. However, when the gap A is less than the required value, the frame may touch the vertical stop...
