Embodiment Construction

[0040] The present invention will be further described below in conjunction with accompanying drawing.

[0041] figure 1 An installation position 100 of a hydraulic bush 1 in a rail train according to an embodiment of the present invention is schematically shown. Such as figure 1As shown, the rail car includes a bogie 11 and wheels 12 . The wheel 12 includes a positioning arm 13 . The hydraulic bushing 1 is connected with the bogie 11 and the wheel 12 at the same time. See the description below for the specific connection method. During the straight running of the rail train, the hydraulic bushing 1 has greater rigidity to help the train move forward stably; Steering is smooth, reducing wear on the wheels 12 and rails.

[0042] figure 2 , 3 , 4 and 5 show an embodiment of the hydraulic bushing 1 . Such as Figure 2-5 As shown, the hydraulic bushing 1 includes a mandrel 20 , a sleeve 47 sleeved on the outside of the mandrel 20 , and an outer sleeve 22 sleeved on th...

Abstract

The invention discloses a hydraulic lining and a rail train. The hydraulic lining comprises a core shaft, a sleeve and an outer sleeve, wherein the sleeve sleeves outside the core shaft; a gap betweenthe core shaft and the sleeve is filled with a first rubber body; a groove is formed in the outer surface of the sleeve; the outer sleeve presses and sleeves outside the sleeve; two liquid cavities used for accommodating liquid are oppositely formed in the first rubber body in the radial direction; the groove and the outer sleeve are enclosed into a runner; and the two liquid cavities communicatewith each other through the runner. After the hydraulic lining is used on the rail train, the rail can be guaranteed to stably forward in a straight-moving process; and moreover, abrasion of wheels and a rail in a curve travelling state can be reduced.

Description

[0001] Cross References to Related Applications [0002] This application claims the rights to the Chinese patent application CN201611095592.5 filed on December 2, 2016 entitled "Hydraulic bushing and rail train" and the Chinese patent application entitled "A hydraulic bushing" filed on December 2, 2016. Priority of patent application CN201611096400.2, the entire content of which is incorporated herein by reference. technical field [0003] The invention relates to the field of rail trains, in particular to a hydraulic bushing which can be used in rail trains. Background technique [0004] The operation of rail trains can be simply divided into two states, the first is a straight state, and the second is a curved state. In the prior art, the wheels are usually connected to the bogie by means of rubber pivot arms, so that the train can run quickly and stably along the rails in a straight-ahead state; and the train can turn smoothly along the track in a curved state.
