Description
Technical field
The utility model relates to a kind of axle raising device.
Background technology
Along with the auto-industry fast development, China's vehicle energy saving environmental issue is outstanding." green " theory of " energy-conserving and environment-protective " is rooted in the hearts of the people gradually, and the environmental issue of large-scale card, passenger vehicle is appeared suddenly more.Large-scale card, the load of passenger vehicle at full load are bigger, and load is less when unloaded, the characteristics of load variations just need to introduce the notion of " supplemental support bridge " when being fully loaded with zero load at its car load, when this bridge of at full load participates in carrying, and load hour promotes this bridge and makes its wheel built on stilts not participate in carrying.So not only reduce the resistance to motion of vehicle but also protected tire, prolonged its service life.At present, the most complex structure of vehicle bridge elevator system of the prior art, cost is higher, and gives the vehicle bridge located lateral bad.
Summary of the invention
At above-mentioned prior art, the utility model provides a kind of axle raising device, and the utility model has just increased by one and promoted air bag and a support and a cover control system on the basis of original air suspension, and structure is simple relatively, implements more convenient.
The utility model is achieved through the following technical solutions:
A kind of axle raising device comprises that vehicle bridge promotes that air-bag support, vehicle frame promote air-bag support, vehicle bridge promotes control setup, and wherein, vehicle bridge promotes air-bag support and is located on the automotive axle, vehicle frame promote air-bag support be located at vehicle bridge promote air-bag support under; Vehicle bridge promotes control setup and comprises gang switch, normally closed solenoid valve, normal open electromagnetic valve, carrying air bag, promotes air bag, air receiver, by pass valve, levelling valve, and wherein, normally closed solenoid valve is connected with the gang switch circuit respectively with the normal open electromagnetic valve; Air receiver, levelling valve, normal open electromagnetic valve, carrying air bag are connected in series by pipeline; Air receiver, by pass valve, normally closed solenoid valve, lifting air bag are connected in series by pipeline, promoting air bag promotes between air-bag support and the vehicle frame lifting air-bag support in vehicle bridge, the carrying air bag then is the used air bag of former air suspension, and present position in the suspension is played by former air in its position; Air receiver is fixed on the vehicle frame by fixed support.
During use, when vehicle zero load or load hour start a gang switch, this moment, normal open and normally closed solenoid valve mode of operation changed: former normally closed solenoid valve is connected, and the normally closed solenoid valve after the connection is given and promoted airbag aeration; Former normal open closed electromagnetic valve carries air bag and exits by the electromagnetic valve after closing simultaneously.Promote air bag like this and uprise, because of promoting air bag lower end and body contact, floor level is constant relatively, promotes air bag vehicle bridge jack-up with the vehicle bridge bonded assembly like this, finally makes its wheel built on stilts, has reached the purpose that vehicle bridge promotes.
Attention: vehicle bridge is by carrying air bag bearing part tare when not promoting, and vehicle bridge has not just been carried in the time of lifting, but vehicle frame is lifted from ground to vehicle bridge by promoting air bag.In addition, normal open electromagnetic valve and normally closed solenoid valve can be changed, when electromagnetic valve is connected quite and pipeline directly connect over.The air bag gas inside can be discharged in the atmosphere by electromagnetic valve and go in the time of closed electromagnetic valve, (this electromagnetic valve is the single-phase electricity magnet valve of a two-bit triplet and the relative air receiver of electromagnetic valve this moment just is equivalent to a plug disconnection air-flow, it connects then, and air receiver is communicated with this moment to airbag aeration with air bag, it closes then that air bag is communicated with atmosphere, this moment air bag deflation).
The utility model is to increase by one on vehicle bridge to promote air-bag support on the basis that former " supplemental support bridge " hangs, under vehicle bridge lifting air-bag support, increase vehicle frame simultaneously and promote air-bag support, in the middle of two stands, stay enough lifting air bag installing spaces and room for promotion then, realize the lifting of vehicle bridge by the control of control system.The utility model is to install one or more " lifting air bags " in the normal air suspension additional, by the interlock (inflation, another is died) of the carrying air bag in control " lifting air bag " and the former air suspension, realizes the lifting of vehicle bridge.
The utility model is simple in structure, and is easy for installation, and cost is low, and result of use is good.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of axle raising device, (this support is directly over the lifting air bag to comprise vehicle bridge lifting air-bag support, the plan area of a sufficient intensity of welding is greater than the area above the air bag and the frame member of not interfering with air bag on vehicle bridge), vehicle frame promotes air-bag support 2, vehicle bridge promotes control setup, as shown in Figure 1 and Figure 2, wherein, vehicle bridge promotes air-bag support and is located on the automotive axle, vehicle frame promote air-bag support 2 be located at vehicle bridge promote air-bag support under; Vehicle bridge promotes control setup and comprises gang switch 4, normally closed solenoid valve 5, normal open electromagnetic valve 6, carrying air bag 3, promotes air bag 1, air receiver 7, by pass valve 8, levelling valve 9, and wherein, normally closed solenoid valve 5 is connected with gang switch 4 circuit respectively with normal open electromagnetic valve 6; Air receiver 7, levelling valve 9, normal open electromagnetic valve 6, carrying air bag 6 are connected in series by pipeline; Air receiver 7, by pass valve 8, normally closed solenoid valve 5, promote air bag 1 and be connected in series by pipeline, carrying air bag 3 promotes air-bag support and vehicle frame promotes between the air-bag support 2 in vehicle bridge.Promoting air bag and carrying air bag all has separately independently support, as shown in Figure 5.
When vehicle bridge does not promote, as shown in Figure 3, during use, when vehicle zero load or load hour start a gang switch 4, this moment, normal open electromagnetic valve 6 and normally closed solenoid valve 5 mode of operations changed: former normally closed solenoid valve 5 is connected, and the normally closed solenoid valve 5 after the connection is given and promoted airbag aeration; Former normal open electromagnetic valve 6 is closed simultaneously, and the carrying air bag is exitted by the electromagnetic valve after closing.Promote air bag 1 like this and uprise, because of promoting air bag 1 lower end and body contact, floor level is constant relatively, promotes air bag 1 vehicle bridge jack-up with the vehicle bridge bonded assembly like this, finally makes its wheel built on stilts, as shown in Figure 4, has reached the purpose that vehicle bridge promotes.
