Description
Technical field
The utility model relates to a kind of Trailer car shaft lift system.Belong to special-use vehicle manufacturing technology field.
Background technology
Most of trailers are in the time of deadhead operation, all tire all lands, and in the process of moving, the friction force on tire and ground strengthens, increase the watt loss of tractor truck, oil consumption strengthens, and has accelerated the wear on tyres of trailer, in order to address this problem, realize by the lifting to Trailer car shaft at present, and existing lift system is to adopt the control cock of the additional complexity of Pneumatic Suspension to realize, Pneumatic Suspension complex structure, and also price comparison is expensive.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of Trailer car shaft lift system is provided, and it is not only simple in structure, is convenient to connect low price; And can promote Trailer car shaft, and reduce the friction force on trailer car tyre and ground, thereby reduce the watt loss of tractor truck, save fuel oil, reduce trailer car tyre wearing and tearing, extend the service life of trailer car tyre.
The purpose of this utility model is achieved in that a kind of novel Trailer car shaft lift system, it comprises lifting air bag, promote crossbeam, fixed cross beam, lift block, elevator bolt, manually actuated control valve, air receiver, vehicle frame, axletree and BF, described fixed cross beam is welded on chassis side rail, described lifting air bag is bolted and is fixed on fixed cross beam, described lifting crossbeam is bolted to be fixed on and promotes air bag upper end, described elevator bolt is through promoting crossbeam and axletree and lift block being fixed on to axletree below with nut, described axletree is fixed on vehicle frame by BF, described hand control valve (HCV) is bolted on frame side member, described air receiver is bolted and is fixed between frame beam, between described air receiver and hand control valve (HCV), be connected with tracheae, between hand control valve (HCV) and lifting air bag, be connected with tracheae.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is simple in structure, be convenient to connect, can promote the Trailer car shaft that BF is housed, low price, easy to operate, and can promote Trailer car shaft, reduce the friction force on trailer car tyre and ground, thereby reduce the watt loss of tractor truck, save fuel oil, reduce trailer car tyre wearing and tearing, extend the service life of trailer car tyre.

The specific embodiment
Referring to Fig. 1-Fig. 3, the utility model relates to a kind of novel Trailer car shaft lift system, comprise and promote air bag 1, promote crossbeam 2, fixed cross beam 3, lift block 4, elevator bolt 5, manually actuated control valve 6, air receiver 7, vehicle frame 8, axletree 9 and BF 10, described fixed cross beam 3 is welded on vehicle frame 8 longerons, described lifting air bag 1 is bolted and is fixed on fixed cross beam 3, described lifting crossbeam 2 is bolted to be fixed on and promotes air bag 1 upper end, and on described lifting crossbeam 2, have hole for wearing elevator bolt 5, described elevator bolt 5 is through promoting crossbeam 2 and axletree 9 and lift block 4 being fixed on to axletree 9 belows with nut, described axletree 9 is fixed on vehicle frame 8 by BF 10, described hand control valve (HCV) 6 is bolted on vehicle frame 8 side bars, described air receiver 7 is bolted and is fixed between vehicle frame 8 crossbeams.In air receiver 7, store the pressurized air of 7Kp pressure, between described air receiver 7 and hand control valve (HCV) 6, be connected with tracheae, between hand control valve (HCV) 6 and lifting air bag 1, be connected with tracheae.
Promote the cylinder that air bag 1 is equivalent to a high thrust, in the time having pressure gas to enter, promote air bag 1 and highly uprise, in the time that pressure gas is discharged, promote air bag 1 and highly diminish.
Hand control valve (HCV) 6 is the two-bit triplet hand control valve (HCV) of a gas circuit, when hand control valve (HCV) 6 buttons are pressed, air receiver 7 is communicated with by hand control valve (HCV) 6 with lifting air bag 1 gas circuit, make air receiver 7 to promoting air bag 1 air feed, in the time that hand control valve (HCV) 6 buttons are extracted, air receiver 7 disconnects with lifting air bag 1 gas circuit, and it is identical with the exhausr port on hand control valve (HCV) 6 by tracheae to promote air bag 1, and the pressurized air promoting in air bag 1 is entered to atmosphere.
In the time that trailer needs deadhead operation, press the button of hand control valve (HCV) 6, the pressurized air of air receiver 7 is entered and is promoted air bag 1 by hand control valve (HCV) 6, pressurized air promotes to promote air bag 1 and highly uprises, promoting air bag 1 drives lifting crossbeam 1 upwards to raise, promoting crossbeam 1 drives elevator bolt 5 upwards to raise, elevator bolt 5 drives lift block 4 upwards to raise again, lift block 4 is raised with axletree 9 contact zones motor-car axles 9 and is upwards raised, and promote steel spring generation elastic deformation, soaring in wheel and ground, finally reaches the object that promotes axletree.In the time that trailer needs load-carrying to travel, the button of pull-out hand control valve (HCV) 6, air receiver 7 disconnects with lifting air bag 1 gas circuit, and promote air bag 1 and enter atmosphere by the exhausr port on hand control valve (HCV) 6, under the effect of deadweight and steel spring power, promote air bag 1 height to decline, and drive lifting crossbeam 1, elevator bolt 5, lift block 4, axletree 9 to decline, final axletree sets back.
