Suspension system designs field.
Background technology
Equalizing suspension system after the heavy-duty commercial vehicle being widely used at present, because of the jackshaft of equalizing suspension system and the load of rear axle
Lotus is identical, and equalizing type of suspension bearing system uses tandem axle structure.According to single drive axle structure, it will cause on wet and slippery road
Face vehicle traction is skidded, can not normally travel.Vehicle in normal road, it is necessary to driving force it is smaller, use double drive
Bridge structure there are driving force it is superfluous the shortcomings that；For drive axle structure relative to bearing bridge structure, internal structure is complicated, weight is big, into
This height；Drive axle internal gear lubricating maintenance is of high cost；Drive axle own gear system resistance is big, and then reduces fuel oil and utilize
Rate, relative to bearing bridge more excessive fuel consumption.Therefore, how a system is provided, makes the jackshaft of equalizing suspension system after heavy-duty commercial vehicle
The structure of bearing bridge is added using single drive axle with rear axle, while become urgent problem to be solved wet-skid road surface vehicle is non-slip.
The content of the invention
To solve the above problems, the purpose of this utility model is to provide equalizing suspension system car after a kind of heavy-duty commercial vehicle
Bridge lifting mechanism, by equalizing type of suspension axle lift mechanism, lifts equalizing type of suspension bearing system rear axle, is used for realization middle rear axle
Load transfer, and then existing equalizing suspension system is used single drive axle structure, equalizing suspension system rear axle can be made to be changed to hold
Bridge is carried, drop weight cost declining is realized, saves fuel oil；Vehicle empty wagons when driving can lift rear axle at the same time, reduce running resistance, avoid
Rear axle tire wear.
What the technical solution of the utility model was realized in：Equalizing suspension system axle lift after a kind of heavy-duty commercial vehicle
Mechanism, is made of air spring, upper cover plate, upper bracket, connecting plate, lower cover, hand-operated valve, relay valve；Balance suspension support with

Embodiment
Clearly and completely described below in conjunction with attached drawing and being done to the utility model, it is clear that described embodiment is this
The part of the embodiment of invention, instead of all the embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art exist
All other embodiments obtained under the premise of creative work are not made, belong to the scope of protection of the invention.One kind weight
Equalizing suspension system axle lift mechanism after type commercial car, by air spring 1, upper cover plate 2, upper bracket 4, connecting plate 3, lower cover
5th, hand-operated valve 15, relay valve 16 form；Balance suspension support 8 is connected with vehicle frame 13 by bolt, and bearing bridge 6 passes through upper anti-work
It is connected with bar 12, lower back reaction rod 11 with balance suspension support 8, drive axle 14 passes through upper back reaction rod 12, lower back reaction rod 11
It is connected with balance suspension support 8, the middle part of leaf spring 9 is connected with balance suspension support 8 by U bolt 10,9 liang of leaf spring
End falls on bearing bridge 6 and drive axle 14, it is characterised in that：Air spring 1 is connected with upper cover plate 2, lower cover 5 by bolt,
Upper cover plate 2 is connected with upper bracket 4 by bolt, and upper bracket 4 is connected with bearing bridge 6 by bolt 7, and lower cover 5 is logical with connecting plate 3
Cross bolt to be connected, connecting plate 3 is connected with vehicle frame 13 by bolt.
When lifting mechanism is opened, air spring 1 is inflated, and air spring 1 passes through lower cover 5, connecting plate 3 and vehicle frame 13
Rigid connection is formed, the lifting force that air spring 1 provides acts on bearing bridge 6 by upper cover plate 2, upper bracket 4, makes bearing bridge 6
Be subject to one it is extra be lifted up power, and because bearing bridge 6 and drive axle 14 are subject to the upward always support force on ground constant, and hold
It is equal with the pressure that drive axle 14 is subject to leaf spring downward to carry bridge 6, therefore masterpiece used time, bearing bridge are lifted up in extra
6 are subject to the sum of the upward support force on ground and lifting force to be approximately equal to the support force that drive axle 14 is subject to ground, so when drive axle
14 are subject to the support force on ground to increase, and then improve the frictional force limit between drive axle 14 and ground, the driving force of lifting system.
As shown in figure 3, axle lift mechanism control system is made of hand-operated valve 15, relay valve 16, the compression that source of the gas provides
Air is supplied to hand-operated valve 15, relay valve 16 by air pipe line at the same time, and hand-operated valve 15 passes through air pipe line and 16 phase of relay valve
Even, relay valve 16 is connected by air pipe line with air spring 1, and when hand-operated valve 15 is opened, control relay valve 16 is opened, air
Spring 1 is inflated, and lifting mechanism is opened, conversely, when hand-operated valve 15 is closed, control relay valve 16 is closed, and air spring 1 is deflated,
Lifting mechanism is closed.Core element of the air spring as lifting mechanism, for providing extra active force to vehicle-mounted bridge, makes to put down
The jackshaft of weighing apparatus suspension is no longer equal with back axle load, the lifting carrying rear axle in zero load, in fully loaded skid, by the load of bearing bridge
Lotus part is transferred to drive axle, lifts driving force.
It will be connected by the structural member that upper cover plate 2, upper bracket 4, connecting plate 3, lower cover 5 are formed below air spring with vehicle frame
Connect, will be connected above air spring with vehicle bridge, realize and the bearing capacity of air spring is transferred to vehicle bridge from vehicle frame.
The control system being made of hand-operated valve 15, relay valve 16 is used for controlling the inflation/deflation of air bag, by user in driver's cabin
Inside control according to the actual requirements, relay valve is controlled by gas circuit using hand-operated valve, and then realize the charging-discharging function of air spring.
Lifting mechanism closed mode, rear equalizing type of suspension carrying situation is consistent with common equalizing type of suspension, because of equalizing type of suspension steel plate
Load is averagely allocated to middle rear axle by spring, and the load that middle rear axle undertakes is identical；When lifting mechanism is opened, vehicle frame passes through lifting
Mechanism is supplied to one upward lifting force of rear axle, makes the load of middle rear axle not releveling, changes equalizing suspension system characteristic, in
The load increase of bridge, the load of rear axle are reduced, and the load that the load of jackshaft is approximately equal to rear axle adds lifting force.Specific works method
It is as follows：
1st, when road conditions are preferable, during vehicle load normally travel, hand-operated valve 15 is closed, and lifting mechanism is closed, and drive axle is with holding
Bridge tire support loads at the same time are carried, single drive axle provides enough driving forces and ensures normal vehicle operation；
2nd, when road conditions are poor, and vehicle load drive axle driving force is insufficient, when tire skids, hand-operated valve 15 is opened,
Drive axle and bearing bridge tire support loads, but fractional load is transferred to drive axle, drive axle load by bearing bridge at the same time at this time
Increase, improves the adhesive force between drive axle tire and ground, and driving force accordingly improves, and vehicle can be made no longer to skid；
3rd, when vehicle empty wagons when driving, hand valve 15 can be opened, 6 tire of bearing bridge lifts, and is not contacted with ground, further
Oil consumption is reduced, while lowers bearing bridge tire wear.
The equalizing type of suspension axle lift mechanism provided by the utility model patent, the matching of rear equalizing type of suspension vehicle bridge can be by
Tandem axle is changed into single drive axle, drops weight cost declining, while saving fuel oil 10% or so, reduces user's vehicle use cost, for
Rapid transit industry cost reduction and automobile energy-saving emission reduction effect are obvious.
