Abstract
The invention relates to a trailer air sac axle lifting device which comprises an air sac lower support, an air sac and an air sac upper support. The air sac upper support is fixed above the air sac through a hexagon head bolt with a hole in the head, adjustable pull rods are symmetrically arranged on the two sides of the air sac upper support, the air sac lower support is arranged below the air sac through hinge pins, connecting rod assemblies are symmetrically arranged on the two sides of the air sac lower support, the other ends of the adjustable pull rods are connected with center holes of the connecting rod assemblies through pull rod hinge pins, supporting blocks are arranged at the other ends of the connecting rod assemblies through supporting block hinge pins, and the supporting blocks are fixedly connected with steel plate springs through fixing bolts and axles. According to the trailer air sac axle lifting device, the trailer axles provided with the steel plate springs in a hung mode can be lifted, friction force between tires of a trailer and the ground can be reduced, the power losses of the trailer are accordingly lowered, fuel is saved, abrasions on the tires of the trailer are reduced, and the service life of the tires of the trailer is prolonged.
Description
Technical field
The present invention relates to a kind of trailer air bag axle raising device.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 expensive.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of trailer air bag axle lift device is provided, it is not only simple in structure, easy for installation; And can promote Trailer car shaft, and reduce the quantity of the trailer car tyre contacting with 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 object of the present invention is achieved like this: a kind of trailer air bag axle raising device, it comprises air bag undersetting, air bag and air bag upper bracket, described air bag upper bracket is fixed on air bag top by six-sided head head eye bolt, bilateral symmetry at described air bag upper bracket is provided with adjustable rod, one end of described adjustable rod is hinged by bearing pin and air bag upper bracket, described air bag undersetting is arranged at air bag below by bearing pin, bilateral symmetry at described air bag undersetting is provided with connecting rod complement, one end of described connecting rod complement and air bag undersetting are hinged, the other end of described adjustable rod is connected with the interstitial hole of connecting rod complement by pull bar bearing pin, the other end at described connecting rod complement is provided with tray by tray bearing pin, described tray is fixedly connected with steel spring with axletree by bolt of rear end plate.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is simple in structure, easy for installation, can promote the Trailer car shaft that BF is housed, 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. 2, the present invention relates to a kind of trailer air bag axle raising device, comprise air bag undersetting 1, air bag 2 and air bag upper bracket 3, described air bag upper bracket 3 is fixed on air bag 2 tops by six-sided head head eye bolt 4, and be connected with axletree, be provided with adjustable rod 5 in the bilateral symmetry of described air bag upper bracket 3, one end of described adjustable rod 5 is hinged by bearing pin and air bag upper bracket 3, described air bag undersetting 1 is arranged at air bag 2 belows by bearing pin, be provided with connecting rod complement 8 in the bilateral symmetry of described air bag undersetting 1, one end of described connecting rod complement 8 and air bag undersetting 1 are hinged, the other end of described adjustable rod 5 is connected with the interstitial hole of connecting rod complement 8 by pull bar bearing pin 7, the other end at described connecting rod complement 8 is provided with tray 10 by tray bearing pin 9, described tray 10 is fixedly connected with steel spring with axletree by bolt of rear end plate 11.
Thereby by trailer air receiver compressed air, this air bag is inflated, and the operation of the inflation/deflation of air bag is controlled by hand valve.In the time of trailer deadhead operation, to airbag aeration, air bag undersetting is declined, the decline drivening rod assembly upset of air bag undersetting, the upset of connecting rod complement drives that holder is fast, axletree, steel spring rise, promoting steel spring generation elastic deformation, soars in wheel and ground, reaches the object that promotes axletree.In the time that trailer load-carrying is travelled, to air bag deflation, make air bag undersetting increase, the rising drivening rod assembly upset of air bag undersetting, the upset of connecting rod complement drives that holder is fast, axletree, steel spring be to decline, and axletree sets back, and vehicle suspension system recovers virgin state.
