Abstract
The utility model discloses a large-tonnage flat car comprising a car frame, a front axle and a rear axle which are connected under the car frame, wherein the front axle adopts the multi-axis hydraulic hanging structure, and the rear axle adopts the one-line double-axle structure. Furthermore, the large-tonnage flat car also comprises a steering linkage mechanism and two steering cylinders, the steering linkage mechanism is connected with the inner side of each hydraulic hanging piece, the two steering cylinders are positioned at the left side and the right side of the car frame, one end of each steering cylinder is connected on the car frame, and the other end is connected with the outer side of one hydraulic hanging piece. By adopting the bearing mode of combining multi-axis hanging with one-line double-axle, the large-tonnage flat car solves the problem of large-tonnage bearing so as to greatly reduce the manufacturing cost, thereby achieving the purposes of economy and practicability.
Description
Technical field
The utility model relates to a kind of large-tonnage transport trolley, is specifically related to a kind of large-tonnage flat bed transport vehicle.
Background technology
Large-tonnage flat truck range of use is wider, more common form is all to adopt hydraulic lift mechanism to form the axis car pattern of multiaxis line, but when this vehicle does not need self to possess Multi Loading and Unloading Functions, adopt this structure just very impracticable, the manufacturing cost of vehicle is bigger, and the input of working service is also more.China's utility model patent 200920142465.5 discloses a kind of like this hydraulic lift mechanism.
" dual axle " is the normal a kind of form that is rigidly connected that adopts on the flat bed transport vehicle, two ends at an equalizing bar respectively are connected to a wheel shaft by spherical hinge, two or four tires are housed on each wheel shaft, form an axis four-wheel-type or eight wheeled versions.Disclose a kind of afterbody floor type flat bed transport vehicle as Chinese utility model patent 99251315.4, its propons and back axle all adopt the version of dual axle, but this structure is difficult to realize the large-tonnage carrying.
The utility model content
The technical problems to be solved in the utility model provides a kind of large-tonnage of can realizing and carries, and can two reduce the flat bed transport vehicle of manufacturing cost again greatly.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of large-tonnage flat truck, comprise vehicle frame and be connected propons and back axle below the vehicle frame, described propons adopts multiaxis line hydraulic suspension structure, and described back axle adopts the dual axle structure.
Preferably, described propons is the biaxial structure that is made of four hydraulic suspensions.
Further, described hydraulic suspension comprises connecting lever, swing arm and hanging oil cylinder, the top of described connecting lever is connected with vehicle frame by swing bearing, one end of the lower end of connecting lever and swing arm is hinged, the other end of swing arm is connected with wheel by minibridge, and the two ends of described hanging oil cylinder are hinged with described connecting lever, swing arm respectively.
Further, comprise that also steering linkage and two turn to oil cylinder, steering linkage is connected with the inboard of each hydraulic suspension, two and arranged on left and right sides that turn to oil cylinder to be positioned at vehicle frame, two turn to an end of oil cylinder to be connected on the vehicle frame, and each is connected the other end with the outside of a hydraulic suspension.
Preferably, described back axle is made of two dual axles, connects eight wheels on each dual axle.
The beneficial effects of the utility model are: adopted the multiaxis line to hang the problem that solves the large-tonnage carrying with the bearing mode of dual axle combination, manufacturing cost is reduced greatly, reached economical and practical purpose.

The specific embodiment
As shown in Figure 1, 2, the utility model large-tonnage flat truck comprises vehicle frame 1 and is connected propons 2 and back axle 3 below the vehicle frame.In the present embodiment, two rows before and after propons 2 is divided into by four hydraulic suspensions 4 constitute the biaxial structure, can be set to an axis, two axis or three axis according to the needs of load-carrying capacity; Back axle 3 is made of two dual axles 5, connects eight wheels on each dual axle 5.
As shown in Figure 3, each hydraulic suspension comprises connecting lever 7, swing arm 9 and hanging oil cylinder 8, horizontal part above the connecting lever 7 is connected with vehicle frame by swing bearing 6, the inner ring of swing bearing 6 is captiveed joint with connecting lever 7 by bolt, captives joint with the lower shoe 11 of vehicle frame by bolt in the outer ring of swing bearing 6; One end of the lower end of connecting lever 7 and swing arm 9 is hinged, and the other end of swing arm 9 is connected with wheel 14 by minibridge 10, and the upper end of hanging oil cylinder 8 is hinged on the horizontal part of connecting lever 7, and the lower end of hanging oil cylinder 8 is hinged on the middle part of swing arm 9.
As shown in Figure 4, steering linkage 13, two turn to oil cylinder 12 and four hydraulic suspensions 4 to constitute the steering hardware of flat trucks, and steering linkage 13 and is connected with the inboard of four hydraulic suspensions 4 between four hydraulic suspensions 4.Two and arranged on left and right sides that turn to oil cylinder 12 then to be positioned at vehicle frame are connected with two hydraulic suspensions 4 at front row respectively, turn to the rear end of oil cylinder 12 to be connected on the vehicle frame, and front end is connected with the outside of front-seat hydraulic suspension 4.
Because hydraulic suspension is connected with vehicle frame by swing bearing, therefore can realize the center rotation of hydraulic suspension according to swing bearing, the hydraulic suspension rotation can drive wheel steering.When turning to oil cylinder 12 to stretch for two, can drive two front-seat hydraulic suspensions, 4 rotations, thereby the wheel steering on the drive first axle, steering linkage 13 also will rotatablely move and pass to two hydraulic suspensions 4 of back row simultaneously, and the wheel that drives on second axis also turns to together.
Each hydraulic suspension turns to the extension line of back each wheel axis of propons to intersect on the line of centers of rear portion dual axle, as shown in Figure 5, thus the steering operation of realization flat truck.
