Problems solved by technology

Due to the long axial liquid injection channel and the small liquid injection hole, the deflection of the drill bit is large during processing, which is difficult to process, and the machining accuracy of the liquid injection hole cannot be effectively guaranteed, and this method needs to be processed to communicate with the liquid chamber in the radial direction. The radial liquid injection channel has high cost and low production efficiency; at the same time, it is easy to cause a lot of residual fluid in the shaft hole, resulting in waste

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereby.

[0032] Such as Figure 1 to Figure 7 The embodiment of the hydraulic bushing for rail transit of the present invention is shown. The hydraulic bushing for rail transit of the present invention is used in the field of positioning of the boom of the high-speed EMU bogie, and can realize a wide range of stiffness adjustment, that is, in the process of linear motion , The hydraulic bushing is in a state of high stiffness, the vehicle can run fast and has high stability, and when the train is turning, the hydraulic bushing is in a state of small stiffness, with a large deformation space, which can realize flexible cornering. In this embodiment, the hydraulic bushing for rail transit includes a rubber main spring 1 and a bushing jacket 2. The bushing jacket 2 is sleev...

Abstract

The invention provides a hydraulic lining for rail traffic. The hydraulic lining comprises a rubber main spring and a lining outer sleeve, wherein the lining outer sleeve sleeves the outer side of therubber main spring; the rubber main spring is equipped with two sealed liquid rooms and a runner for communicating the two sealed liquid rooms; the runner is arranged on the periphery of the rubber main spring; a liquid injecting hole is formed in the lining outer sleeve; and the liquid injecting hole is in butt joint and communication with the runner. The hydraulic lining has the advantages of being simple to process, high in precision and low in cost.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of Chinese patent application CN201611095592.5 filed on December 2, 2016 and Chinese patent application CN201611096400.2 filed on December 02, 2016, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a bogie, in particular to a hydraulic bushing for rail transit. Background technique [0004] The existing hydraulic bushing products are all used in the field of automobile suspension, mainly to meet the requirements of high stiffness and large damping at low frequencies or small stiffness and small damping at high frequencies, so as to achieve the purpose of quickly attenuating vibration and noise reduction. At present, hydraulic bushings There is no relevant application in the field of rail transit. The hydraulic bushing on the existing automobile usually realizes liquid injection by opening a liquid injection channe...
