And be threadedly coupled with blocking, leading screw bottom is connected through lower house bottom and with lower house lower rotation, is worn at the top of the guide rod
Enter to block and be slidably connected with blocking, guide rod bottom is connected with lower house bottom.
Further, including two rubber counterdies for being respectively distributed to dividing plate two bottom sides, the dividing plate and rubber counterdies it
Between form lower chamber body, the leading screw and guide rod are between two rubber counterdies.
Further, the blocking includes core body and body, and elastic skeleton is provided between the core body and body.
The beneficial effects of the utility model：
1) hydraulic suspension device of the present utility model, the degree stretched into the first passage is blocked by controlling, can adjust
The sectional area of first passage ventilation, so as to reach the purpose of adjustment output damping force and rigidity, isolation frequency is effectively widened
Scope, improve vibration isolating effect.
2) blocking includes core body and body, and elastic skeleton is provided between the core body and body, on the one hand, blocks
With retractility so that it is Elastic Contact to block with the first passage, improves service life, on the other hand, body and core body

Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation blocked.
Embodiment
The utility model is described in detail below with reference to accompanying drawing.As shown in Figure 1-2, automobile using of the present utility model
Hydraulic mount, including the housing of top end opening, the rubber spring 2 that sets and be plugged in housing tip opening and it is arranged at housing
The rubber counterdies 4 of inside bottom, base are provided with the rubber spring, the housing every magnetic aluminum alloy materials by being made, institute
State base to be made up of metal materials such as copper, iron, fluid injection steam vent is provided with base, fluid injection steam vent runs through rubber spring, rubber
Fixed between the main spring of glue and upper shell and rubber spring and base by fluid technology, using have concurrently fluid injection and exhaust two kinds of work(
The large diameter hole structure of energy simplifies the structure of suspension, sealing property is more preferable, in addition to is connected with engine as fluid injection steam vent
Connecting rod 3, the connecting rod upper end is fixedly connected by the center screw thread of base with base, and the housing includes passing through bolt
The upper shell 1a and lower house 1b of connection, formed between the rubber spring and rubber counterdies closed and full of ethylene glycol liquid
Chamber, the dividing plate 6 that chamber is divided into upper chamber body 5a and lower chamber body 5b is provided with the chamber, the is provided with the middle part of the dividing plate
One air chamber 7, decoupling film 8 is provided with the top of first air chamber, the is formed between the rubber counterdies and lower housing cavity
Two air chambers 9, the first passage 10 is provided between first air chamber and the second air chamber, is set on the lower casing body wall
