Embodiment Construction

[0043] The present invention will be further described below in conjunction with accompanying drawing.

[0044] Such as figure 1 As shown, the hydraulic bushing 1 includes a main spring 100 and a cylindrical casing 200 . Such as figure 2 and 3 As shown, the main spring 100 has a mandrel 101 , a first rubber body 102 and a sleeve 103 . The first rubber body 102 is sheathed on the outer wall of the mandrel 101 . Two liquid chambers 104 are arranged on the first rubber body 102, and each liquid chamber 104 is a through hole penetrating along the axial direction of the first rubber body 102, and in the radial direction of the first rubber body 102, the two liquid chambers 104 Relative interval distribution. The sleeve 103 is sheathed on the outer wall of the first rubber body 102 . Meanwhile, a groove 110 is provided on the wall of the sleeve 103 . Wherein, the main spring 100 is disposed in the inner cavity of the casing 300 , so that the casing 300 and the sleeve 103 fo...

Abstract

The invention relates to a seal assembly used for a hydraulic bushing and the hydraulic bushing. The seal assembly comprises a rigid support ring assembly and a second rubber body. The support ring assembly is provided with an assembly ring and a convex ring protruding outwards in the radial direction from the outer wall of the assembly ring. The assembly ring is sleeved with the second rubber body in a manner that the convex ring is coated with the second rubber body. The seal assembly can improve the axial stiffness of the hydraulic bushing so that the purpose of adjusting the axial stiffness of the hydraulic bushing by changing the radial stiffness of the seal assembly can be realized.

Description

[0001] Cross References to Related Applications [0002] This application claims the Chinese patent application CN201611096400.2 filed on December 02, 2016 entitled "A Hydraulic Bushing" and the patent application entitled "Hydraulic Bushing and Rail Train" filed on December 02, 2016 The priority of Chinese patent application CN201611095592.5, the entire content of which is incorporated herein by reference. technical field [0003] The invention relates to the technical field of rail trains, in particular to a sealing assembly and a hydraulic bushing for a hydraulic bushing. 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...
