A cab air-spring damping and suspending device pertains to the automobile accessory field. In order to resolve the drawbacks of the prior suspending device, the utility model provides a cab air-spring damping and suspending device that uses an air spring to realize the damping of a cab. The utility model is composed of a module beam, an air spring, a left-right frame, a damper, a reaction tension-torsion plate, a buffering colloid, a height sensor, a pressure regulating valve, a swing rod, a double-head ball-pin link bar, and a cross bearing plate. The utility model has good damping effect and low manufacturing cost, and be directly arranged to cooperate with the cab of the cab-over-engine autos manufactured by a plurality of manufacturers and the cab of the cab-over-engine autos of domestic various auto-types, with much wide adaptability.

Description

Operator's compartment air bellow vibration damping suspending apparatus
Technical field:
The utility model belongs to automobile associate member field.
Background technology:
The suspending apparatus of domestic present flat fronted car operator's compartment of the prior art is to adopt two kinds of modes that suspend basically, and a kind of is the V-type rubber block form that suspends.Another kind is the coil spring form that suspends.Its weak point is, the damping behavior of these two kinds of Cab mounting forms does not all the possess air bellow absorbing that is had, the multiple good damping behavior of vibration damping.Because the driver and crew in the long-distance transport automobile cab, when in having a rest by turns, can not get rest fully continuously, be extremely dangerous to traffic safety.
Summary of the invention:
In order to address the above problem, the utility model provides a kind of operator's compartment air bellow vibration damping suspending apparatus that operator's compartment is carried out vibration damping with air bellow.
Structure of the present utility model is:
A, hydraulic efficiency gear connecting rod 21 is installed on operator's compartment 17, the latch hook bar 19 on the crossbeam 20 of the latch hook 14 on the hydraulic efficiency gear connecting rod 21 and operator's compartment 17 lower ends cooperates; The baffle plate of installing on the buffering blob of viscose 16 of crossbeam 19 upper ends and the operator's compartment 17 22 contacts;
B, in crossbeam 20 lower ends otic placode 8 is installed, arm-tie 9 is turned round in otic placode 8, counteraction, upright support plate 6 connects by bearing pin 7, and upright support plate 6 is installed on the support 2;
C, at crossbeam 20 and 2 on support air bellow 5 is installed, air bellow 5 communicates with air receiver 23, and air bellow 5 and 23 of air receivers are equipped with pressure regulating valve 18; Shock absorber 10 1 ends are fixedly mounted on the crossbeam 20, and the other end is connected with support 2 by shock absorber bearing pin 4;
D, levelling valve 15 is installed on crossbeam 20, levelling valve 15, fork 11, double end ball pin link rod 12, horizontal support plate 13 connect by bearing pin, and horizontal support plate 13 is installed on the support 3 by bearing pin;
E, on support 3, longeron card 1 is installed by bolt 2.
The flat fronted car operator's compartment air bellow suspending apparatus that the utility model is simple in structure, with low cost, comfortable, steady, safe.
1, cheap for manufacturing cost, simple in structure, can be complementary with the cab-over-engine vehicle operator's compartment of domestic plurality of specifications different manufacturers production and effectiveness in vibration suppression is much better than the suspension damping effect of prior art.
2, according to the damping behavior of air bellow and the little ratio damping shock absorber of science coupling is greatly improved traveling comfort, for the driver and crew of long-distance driving provide special quality rest condition, driver and crew have been reduced to a great extent owing to tired safety hazard of driving to cause.
3, when operator's compartment need overturn, open that operator's compartment air bellow vibration damping suspending apparatus is independently irrelevant with operator's compartment behind the latch hook.Shock absorber and rubber air spring are separate installations, bear cushioning effect jointly.
4, good damping result and low cost of manufacture can directly be mated installation with the cab-over-engine vehicle operator's compartment of a plurality of manufacturer production of domestic multiple vehicle, and comformability is very extensive.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
The utility model concrete structure is:
A, hydraulic efficiency gear connecting rod 21 is installed on operator's compartment 17, the latch hook bar 19 on the crossbeam 20 of the latch hook 14 on the hydraulic efficiency gear connecting rod 21 and operator's compartment 17 lower ends cooperates; The baffle plate of installing on the buffering blob of viscose 16 of crossbeam 19 upper ends and the operator's compartment 17 22 contacts;
B, in crossbeam 20 lower ends otic placode 8 is installed, arm-tie 9 is turned round in otic placode 8, counteraction, upright support plate 6 connects by bearing pin 7, and upright support plate 6 is installed on the support 2;
C, at crossbeam 20 and 2 on support air bellow 5 is installed, air bellow 5 communicates with air receiver 23, and air bellow 5 and 23 of air receivers are equipped with pressure regulating valve 18; Shock absorber 10 1 ends are fixedly mounted on the crossbeam 20, and the other end is connected with support 2 by shock absorber bearing pin 4;
D, levelling valve 15 is installed on crossbeam 20, levelling valve 15, fork 11, double end ball pin link rod 12, horizontal support plate 13 connect by bearing pin, and horizontal support plate 13 is installed on the support 3 by bearing pin;
E, on support 3, longeron card 1 is installed by bolt 2.Longeron card 1 is used to be stuck in the longeron of automobile bottom.
The back lower place two side shields of operator's compartment contact the back with the buffering blob of viscose that install top, crossbeam both sides and catch on the latch hook bar with latch hook, and operator's compartment and crossbeam are firmly connected together, and relative motion can not be arranged.The loam cake of the air bellow of installing with the support top, the left and right sides of M12 * 4 Bolt Connection in longeron both sides, the operator's compartment back lower place connects below crossbeam.An end of mounting dampers on the shock absorber bearing pin of the inboard welding of left and right sides support simultaneously, the other end is connected to below the crossbeam.
On the support upper plate of the left and right sides, also be welded with riser, also be welded with otic placode below the crossbeam, between riser and otic placode, connect counteraction and turn round arm-tie with bearing pin.
Its automatic control process of operator's compartment air bellow vibration damping suspending apparatus is: from the next high pressure air direct entry altitude valve after the pressure regulating valve pressure regulation of gas receiver, when operator's compartment is lower than setting height, levelling valve and crossbeam are to moving down, at this moment being connected in fork below the levelling valve on the crossbeam runs into contact below the levelling valve and gas circuit is opened in air bellow inflate, make the air bellow elongation lift crossbeam and operator's compartment.On the contrary, levelling valve contact and fork that operator's compartment is connected on the crossbeam when surpassing setting height leave, at this moment the air bleed hole in the levelling valve is opened by contact, high pressure gas in the air bellow is discharged, deflation hole is plugged again when making the air bellow height drop to setting height, crossbeam and operator's compartment drop to setting height, finish the automatic guidance of lifting, decline like this.
The utility model is realized by following proposal; High pressure gas from gas receiver comes behind pressure regulating valve, enter air bellow through levelling valve, and the bottom of air bellow connects with the upper plate of left and right sides support, and the loam cake of air bellow connects with the bottom of crossbeam.The two ends of gas filed air bellow bearing cross beam are equipped with shock absorber between left and right sides support and the crossbeam simultaneously.The vibrations that road surface and wheel cause in the running car are absorbed by air bellow and shock absorber, and operator's compartment is in very steady, comfort conditions, and the height of operator's compartment remains unanimity, and are irrelevant with load weight in the operator's compartment.
