Description
Technical field
The present invention relates to automobile manufacturing field, specifically a kind of monoblock cast air suspension with gas storage function is horizontal
Beam.
Background technology
At present, with the development of truck hydraulic pressure and pneumatic control system technology, gas consumption of the vehicle to compressed air
Significantly increase.In order to meet requirement that vehicle gas consumption increases, solution mainly has two kinds：1. improve compressed air system pressure
Power；2. increase gas receiver capacity or quantity.Compressed air system pressure is improved, it is necessary to which gas circuit correlation kit meets its property
Can, implement more complicated.Therefore, it is the measure easily realized to increase gas receiver capacity and quantity.But the arrangement of gas receiver
Increasing number, cause problems with：Increase the weight and cost of brakes；It is more in SWB vehicle or system configuration part
Vehicle, such as tractor have that gas receiver arrangement space is narrow and small or the phenomenon of difficult arrangement.
Therefore, for above-mentioned phenomenon, a kind of crossbeam with gas storage function is just refer in patent CN204527327U
Assembly, it includes crossbeam body, back axle control module, enters outlet interface, discharging valve interface and support etc.；Crossbeam body is pipe
Shape body uses as caisson, crossbeam body preferably by two symmetrical crossbeam connectors and a tubular body welding fabrication,
While strengthening longitudinal beam intensity, the caisson of closing is formed；Crossbeam connector is provided with into outlet interface, bolt connection
Bearing, discharging valve interface and distance rod connects bearing.Enter outlet interface by air pipe and joint by source of the gas, crossbeam body and
Back axle control module is connected, and bolt connection is carried out with longitudinal beam on crossbeam connector.The present invention is same increase gas storage volume
When, vehicle gas receiver quantity is reduced, can accordingly reduce the weight and cost of brakes, saves arrangement space；Due to horizontal stroke
Beam assembly is arranged close to vehicle bridge, integrates each valve members such as back axle control module, reduces air path elements quantity, shortens air pipe length,
Improve the braking response time.
In said structure, use although being used as air container using crossbeam, so as to reduce gas receiver quantity, save
The arrangement space of vehicle.But its crossbeam body is split-type structural, using by a tubular body and two symmetrical crossbeams
Connector is welded, and crossbeam body needs to use instead of gas receiver, therefore sealing property requires very high, for welding
The requirement of quality is stricter, also relatively high simultaneously for the required precision between part, the fiber crops that manufacture, assembling are also just compared
It is tired；In addition, for crossbeam ectosome, it is used for the left-right longeron of connecting vehicle frame, so if if wall thickness is too thin, beam pipe
The structural strength of body cannot ensure, so as to have influence on overall connection, still, the crossbeam body needs to come as gas receiver again
Use, if if wall thickness is too thick, the gas of storage also just accordingly tails off.
The content of the invention
, can the technical problem to be solved in the present invention is to provide a kind of monoblock cast air suspension crossbeam with gas storage function
On the basis of ensureing to supply, the sealing property of crossbeam is improved, and ensures the structural strength of crossbeam, while is manufactured more square
Just.
In order to solve the above technical problems, the technical scheme is that：A kind of overall cast beam with gas storage function, should
Crossbeam is used for the left-right longeron of connecting vehicle frame, and its innovative point is：The crossbeam includes
One main body of cross-beam, the main body of cross-beam by a crossbeam body and be symmetricly set on for a pair crossbeam body both ends longeron connect
Flange as a whole casting forms, while going back integral casting forming on the outer wall of crossbeam body has V-type to push away a group, the crossbeam body
For the tubular structure of a both ends open, while there is the intracavity inter-connection with crossbeam body at the both ends in beam pipe long axis of body direction
An air inlet, a gas outlet, be additionally provided with the inwall of the crossbeam body and strengthen convex tendon group；
A pair of end covers for being arranged on beam pipe long axis of body direction both ends, the cross section t shape of the end cover, and it is close
The small one end of end-blocking lid bore is stretched into the cavity of crossbeam body and is connected by bolt and crossbeam body, in end cover
It is also equipped with being bonded the sealing ring group of crossbeam inboard wall of tube body on one section of the outer wall stretched into crossbeam body cavity.
Further, the V-type pushes away seat group one and shares two groups, is symmetrically distributed in the both ends of crossbeam body, and every group of V-type pushes away seat
Group pushes away seat by two V-types for being symmetrically distributed in beam pipe long axis of body direction both ends and collectively formed.
Further, reinforcement convex tendon is additionally provided with the inwall of crossbeam body, the reinforcement convex tendon is located in beam pipe body
The corresponding opening position of seat is pushed away with V-type on wall, and pushes away seat with V-type and corresponds.
Further, the V-type push away seat thickness account for crossbeam body diameter 1/3-1/2.
Further, the sealing ring group is collectively formed by the O-ring seal of two and column distribution, while in end cover
The upper annular groove with appearance O-ring seal insertion.
Further, there is a blind hole for holding end cover installation, the depth of the blind hole >=close on longeron adpting flange
One section of thickness of the end-blocking lid positioned at the external side of beam pipe.
Further, the side being connected on the longeron adpting flange with longeron is additionally provided with boss, in longeron connection method
The liner plate of connection, the thickness of the boss and the consistency of thickness of liner plate are additionally provided between blue and longeron.
The advantage of the invention is that：In the present invention, integrally cast by the way that crossbeam body, crossbeam connector and V-type are pushed away into seat
Make and form, so as to reduce the assembling between three, while also reduce machining accuracy, convenient processing, and using overall casting
The mode of type is caused, also just reduces the connection processing between part, corresponding sealing property is also just improved；Adopt in addition
The end cover being connected with, which realizes crossbeam body, to be sealed, also for facilitating follow-up japanning, preservative treatment.
Strengthen convex tendon by being set at the inwall of crossbeam body, avoid causing crossbeam body because of the installation that V-type pushes away seat
The inwall at place is thinning and causes crossbeam body structural strength to be affected, and ensure that the overall structural strength of crossbeam body.
The design of seat is pushed away for V-type, by the way that V-type to be pushed away to the 1/3-1/2 of the thickness control of seat in the diameter of crossbeam body, from
And thickeied V-type and pushed away seat, follow-up processing and fabricating is facilitated, ensure that structural strength.
Setting for sealing ring group, end cover and beam pipe are realized by the O-ring seal of two and column distribution
Sealing between body, using the structure of this dual-seal, so as to effectively improve its sealing effectiveness.
Hold the blind hole of end cover by being set on longeron adpting flange, on the basis of end cover installation is ensured,
Avoid end cover protrusion longeron adpting flange outer and interfere with the installation between longeron adpting flange and longeron.
And boss is set on longeron adpting flange, so as to be supported to being formed between longeron adpting flange and longeron, keep away
Exempt to have influence on the stabilization of connection because liner plate causes existing gap between longeron adpting flange and longeron.
Crossbeam in the present invention can also be arranged on speed changer portion in addition to making Guan Liang uses on hollow suspension
Make gas receiver use in part, the fluctuation of air pressure when can be used to compensate shift of transmission so that gearshift is more steady.
