Abstract
The utility model discloses a tractor with a liftable saddle, which comprises an entire tractor front suspension and an entire tractor rear suspension, wherein and the entire tractor rear suspension is connected with a saddle lift system. Compared with the old-style structure, the tractor has good shock-absorbing effect in entire tractor heavy loading state and strong carrying capacity of the drive axle, thereby suiting larger tonnage merchandise; and the lift system can realize the combination with and separation from a trailer car, thereby achieving high transportation efficiency.
Description
Technical field
The utility model relates to a kind of automobile, but the tractor truck of particularly a kind of 6X4 saddle lifting.
Background technology
Along with the continuous development of China harbour and steel mill, transit industry is all developing rapidly, but increasing to the demand of saddle lifting tractor truck with high bearing capacity.But but the tractor truck of present harbour and the used saddle lifting of steel mill all is a 4X2 rigidity rear overhang tractor truck, and the back hangs does not almost have damping for being rigidly connected.And the 6X4 tractor truck all is a saddle fixation formula tractor truck, and saddle can not lifting, greatly reduces conveying efficiency.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiencies in the prior art, but a kind of saddle lifting tractor truck of simple in structure, economic and reliable is provided.
For achieving the above object, the utility model has adopted following technical scheme:
But saddle lifting tractor truck hangs after comprising car load, it is characterized in that, hangs the saddle hoisting system of ining succession behind the car load.
Described saddle hoisting system comprises the elevating ram collet, the elevating ram collet directly is welded on the chassis side rail lower aerofoil, the elevating ram collet links to each other with the elevating ram lower end, the elevating ram upper end is installed in the lifting swing arm, lifting swing arm front end is installed on the chassis side rail by thru shaft, and the rear end is connected with saddle.
Described car load rear overhang satchel is drawn together middle drive axle, rear driving axle, lower thrust rod, upper thrust rod, hydro-pneumatic spring and limiting stopper, middle drive axle lower end links to each other with the elevating ram collet of saddle hoisting system by lower thrust rod respectively with the rear driving axle lower end, middle drive axle upper end and rear driving axle upper end are installed on the cross member of frame by upper thrust rod respectively, middle drive axle links to each other with the hydro-pneumatic spring lower end respectively with the rear driving axle axle housing, the hydro-pneumatic spring upper end is installed on the chassis side rail, and described limiting stopper is directly installed on the chassis side rail lower aerofoil.
During vehicle ', middle drive axle and rear driving axle pass to vehicle frame to power by upper and lower propelling rod, and hydro-pneumatic spring plays cushioning effect.Limiting stopper plays heavily loaded position-limiting action.Its hoisting system of lifting may command of saddle makes elevating ram elongate or shorten, and this moment, the lifting swing arm was rotated around the front end thru shaft.Thru shaft plays draw simultaneously.
The utility model is compared with old-fashioned structure, good damping effect when being the car load heavy duty, and the drive axle load-carrying capacity is strong, adapts to than the large-tonnage goods; The combination that hoisting system can be realized trailer with separate the conveying efficiency height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1, middle drive axle 2, rear driving axle 3, lower thrust rod 4, hydro-pneumatic spring 5, upper thrust rod 6, limiting stopper 7, elevating ram collet 8, elevating ram 9, lifting swing arm 10, saddle 11, thru shaft 12, chassis side rail 13, cross member of frame.
The specific embodiment
Below in conjunction with accompanying drawing and enforcement the utility model is described further.
In Fig. 1, but saddle lifting tractor truck hang after comprising car load, hang the saddle hoisting system of ining succession behind the car load.The saddle hoisting system comprises elevating ram collet 7, elevating ram collet 7 directly is welded on chassis side rail 12 lower aerofoils, elevating ram collet 7 links to each other with elevating ram 8 lower ends, elevating ram 8 upper ends are installed in the lifting swing arm 9, lifting swing arm 9 front ends are installed on the chassis side rail 12 by thru shaft 11, and the rear end is connected with saddle 10.Car load rear overhang satchel is drawn together middle drive axle 1, rear driving axle 2, lower thrust rod 3, upper thrust rod 5, hydro-pneumatic spring 4 and limiting stopper 6, middle drive axle 1 lower end links to each other with the elevating ram collet 7 of saddle hoisting system by lower thrust rod 3 respectively with rear driving axle 2 lower ends, middle drive axle 1 upper end and rear driving axle 2 upper ends are installed on the cross member of frame 13 by upper thrust rod 5 respectively, middle drive axle 1 links to each other with hydro-pneumatic spring 4 lower ends respectively with rear driving axle Bridge 2 shell, and hydro-pneumatic spring 4 upper ends are installed on the chassis side rail 12.Limiting stopper 6 is directly installed on chassis side rail 12 lower aerofoils.
During vehicle ', middle drive axle 1 and rear driving axle 2 pass to vehicle frame to power by upper and lower propelling rod, 4 cushioning effects of hydro-pneumatic spring.6 heavily loaded position-limiting actions of limiting stopper.Its hoisting system of lifting may command of saddle makes elevating ram elongate or shorten, and lifting swing arm 9 this moment is rotated around front end thru shaft 11.Thru shaft plays draw simultaneously.
