Abstract

The utility model is related to a kind of hydraulic damping shock absorbing seat, including seat (1), mounting bracket (2), bearing (4), described seat (1) bottom sets bearing (4), bearing (4) is in mounting bracket, also include at least one hydraulic damping device (3), the hydraulic damping device (3) connects mounting bracket (2) and bearing (4) respectively.Compared with prior art, the utility model causes that the vibration that engineering machinery is produced in operation process is absorbed by hydraulic damping device, so as to prevent body vibrations to be transferred to seat, it is to avoid because seat vibration causes the fatigue of driver and health damage, improve the comfortableness taken.

Description

A kind of hydraulic damping shock absorbing seat
Technical field
The utility model is related to vibration damping field, relates in particular to a kind of engineering machinery shock absorbing seat.
Background technology
Engineering machinery, such as loading machine, because operating load is big, operating mode is poor, along with substantial amounts of vibration, can reduce driving The riding comfort of person, easily causes driver's fatigue, and long drives can even be detrimental to health, and causes to damage.For this feelings Condition using effective method, it is necessary to completely cut off or reduce the influence that vibration is transferred directly to human body.Existing seat is simple In driver's cabin, simple structure, but cannot effectively completely cut off or reduce vibration transmission.Such as patent CN103332128B Disclose a kind of vibration-damping seat for automobile, including base support body, the backrest support body that is arranged on base support body and taken for user The bearer connection part of sheet, the bottom of bearer connection part is connected on base support body, wherein, the vibration-damping seat for automobile is also wrapped A shock absorber and a sliding bar are included, sliding bar is arranged on backrest support body in can slide up and down, and sliding bar is in backrest support body Upper lateral arrangement, the top of bearer connection part is connected on sliding bar, and shock absorber is on base support body or backrest support body and has There is the output end of an elastic telescopic, output end is connected with sliding bar.So that vibration-damping seat for automobile have it is simple and reliable for structure, Simple and convenient advantage is installed in combination, and then greatly reduces the cost that production and combination are installed, and reduces vapour of the invention Space shared by car shock absorbing seat, substantially increases adaptability.
Although the seat also has effectiveness in vibration suppression, the damper is not to be suitable for that load is big, work on the device chair back The engineering machinery of condition difference.
The content of the invention
The purpose of this utility model be exactly provide one kind for the defect for overcoming above-mentioned prior art to exist can be significantly Eliminate influence of the judder produced during engineer machinery operation to seat, it is to avoid the hydraulic damping vibration damping of the generation of resonance Seat.
The purpose of this utility model can be achieved through the following technical solutions:A kind of hydraulic damping shock absorbing seat, including Seat, mounting bracket, bearing, described seat bottom set bearing, and bearing is arranged in mounting bracket, it is characterised in that also Including at least one hydraulic damping device, the hydraulic damping device connects mounting bracket and bearing respectively.
Described mounting bracket includes base plate and at least two fix bars, and each fix bar one end is connected on base plate, another End connects bearing.
Described base plate is provided with least 2 mounting holes, is fixedly connected with vehicle body by each mounting hole.
Described fix bar one end is welded on base plate, and the other end is provided with pin-and-hole, with bearing hinge-coupled.
Described abutment memberization is set, and at least three projections is which is provided with, respectively with mounting bracket and hydraulic damping Device is connected.
Described hydraulic damping device includes body and mobile bar, and body one end connection mounting bracket, other end connection is moved Lever, mobile bar connects bearing, and it is provided with the back-moving spring for making mobile bar reset.Hydraulic damping device inside is equipped with hydraulic air Oil.
Described hydraulic damping device constitutes quadric chain with mounting bracket and bearing:Bearing is used as linkage One composition component, is hinged with mounting bracket, while another ring of the hydraulic damping device as linkage, with mounting bracket It is hinged with bearing.
Compared with prior art, the utility model passes through modular hydraulic shock-absorption component, by bearing, mounting bracket, liquid Pressure damper constitutes hydraulic damping shock absorbing seat, so that the vibration that engineering truck is operationally produced is by hydraulic damping device Isolation is absorbed, so as to prevent the vibration of seat, while the damped frequency of liquid differs larger with machinery, the product of resonance can be avoided It is raw, so as to prevent vibration to be transferred to seat, improve the riding comfort of driver, it is ensured that the operating efficiency of driver.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is bar linkage structure sketch of the present utility model;
Reference:1. seat, 2. mounting bracket, 3. hydraulic damping device, 4. bearing, 21. mounting bracket base plates, 22. Mounting bracket fix bar, 31. mobile bars, 32. bodies.
Specific embodiment
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1-2, a kind of hydraulic damping shock absorbing seat, including seat 1, mounting bracket 2, hydraulic damping device 3, branch Seat 4.
Described mounting bracket 2 includes the fix bar 22 of base plate 21 and at least two, and described base plate 21 is provided with least 2 Mounting hole, easily can be fixedly connected by each mounting hole with Mechanical Engineering Body.Each fix bar 22 (has two in the present embodiment It is individual) one end is welded on base plate 21, and the other end is provided with pin-and-hole, with the hinge-coupled of bearing 4.
Bearing 4 plays the function of support seat 1, and installed in the bottom of seat 1, the described modularization of bearing 4 is set, while its It is upper that there are at least 3 projections, it is hinged with fix bar 22 and hydraulic damping device mobile bar 31 respectively.
Hydraulic damping device 3 at least one (two are provided with the present embodiment), described hydraulic damping device 3 includes this Body 32 and mobile bar 31, the one end of body 32 connection mounting bracket 2, other end connection mobile bar 31, the connects bearing 4 of mobile bar 31, And it is provided with the back-moving spring for making mobile bar 31 reset.Hydraulic damping device 3 is connected with base plate 21 and bearing 4, constitutes double leval jib Mechanism, the mobile bar 31 of hydraulic damping device can be relatively moved along body 32, and aircraft fluid is full of in body 32, can work Under work and severe cold high-heat environment, while being provided with an at least back-moving spring, there is provided the restoring force of mobile bar 31.
When Mechanical Engineering Body is impacted by high vibration, the mobile bar 31 of hydraulic damping device will overcome back-moving spring The vibration acceleration of power and car body, relatively moves with body 32, eliminates the influence of body oscillating.Once vibration is eliminated, move Lever 31 will again reset in the presence of the restoring force of back-moving spring.Due to the frequency characteristic of fluid damping and mechanical oscillation frequently Rate difference is larger, can avoid seat that the phenomenon of resonance is produced with the vibration of car body, effectively avoids and eliminate vibration to seat Influence.
