Abstract
The utility model relates to an overall double-beam frame of a three-wheel truck, which comprises a main beam (1) and a secondary beam (2). The front end of the secondary beam (2) is connected with the rear end of a fuel tank seat supporting beam (5) through a front crossbeam (6), the front end of the fuel tank seat supporting beam (5) is connected with a main pipe (3), the fuel tank seat supporting beam (5) and the main pipe (3) are connected with one end of the main beam (1) through a connecting box (4), and the middle part of the main beam (1) is gradually close to the secondary beam (2) from bottom to top and from the inner to the outer. The overall double-beam frame is characterized in that the rear part of the secondary beam (2) extends backwards, the extended section of the secondary beam (2) clings to the rear horizontal section of the main beam (1), and the rear end of the secondary beam (2) is aligned with the rear end of the main beam (1). Due to the overlapping and welding of the rear parts of the main beam and the secondary beam, the utility model improves the load-bearing capacity. The rear bending part of the main beam can not be easily broken, and the rear lug can bear more force, thereby prolonging the service life of the frame.
Description
Technical field
The utility model belongs to the tritruck vehicle frame, specifically a kind of integral type twin beams vehicle frame of tritruck.
Background technology
Tricycle frame is the vitals in the three-wheel vehicle, the girder of existing tricycle frame, secondary beam and fuel tank seat support beam are symmetrically distributed in the both sides of vehicle frame, the secondary beam front end is connected with fuel tank seat support beam by front cross rail, the rear end of secondary beam be welded on behind the girder crook be the girder middle part from bottom to top, turning from inside to outside, this structure has been pressed on the girder of vehicle frame the weight capacity of tricycle frame.Again because girder by root timber material bending forming repeatedly, material through repeatedly bend or stretch bending after to its material and stressed influential, can reduce the ability of vehicle frame load-bearing, therefore, when vehicle frame bears a large amount of strength, girder just ruptures easily with the crook, back, has shortened the service life of vehicle frame.
The utility model content
The purpose of this utility model is: the whole twin beams vehicle frame of tritruck of the whole load-bearing of a kind of vehicle frame main beam and secondary beam is provided, and low with the ability of the vehicle frame load-bearing that overcomes prior art, behind the girder rupture easily in the crook, the shortcoming that service life is short.
For achieving the above object, the utility model provides a kind of tritruck whole twin beams vehicle frame, comprise girder and secondary beam, this secondary beam is arranged on the top at girder middle part, the front end of described secondary beam is connected by the rear end of front cross rail with fuel tank seat support beam, the front end of described fuel tank seat support beam is connected with the person in charge, described fuel tank seat support beam is connected with an end of described girder by connecting box with being responsible for, the middle part of this girder is from bottom to top from inside to outside gradually near secondary beam, its key is: described time beam rear part extends back, the extension of this secondary beam abuts in the rear horizontal section of described girder, aligns with main beam rear end in the rear end of described secondary beam.
The utility model adopts time beam rear part to extend back, and the structure of aliging with main beam rear end in its rear end can make tricycle frame's girder and secondary beam be combined into an integral body, has strengthened the load-carrying capacity of vehicle frame.Behind the girder can not rupture in the crook, and simultaneously back hanger holding capacity is strengthened, thereby improved vehicle frame service life yet.
Be provided with the hinge of leaf spring mounting pipe between described girder and the secondary beam, two ends of described hinge of leaf spring mounting pipe stretch into respectively between girder and the secondary beam crevice place, and with contiguous block and girder and secondary beam welding.Adopt this structure can make the hinge of leaf spring mounting pipe not influence girder and secondary beam is structural complete installing, make girder and secondary beam be not easy to cause damage.
The end of described hinge of leaf spring mounting pipe is equipped with preceding hanger, and the rear portion of described girder is equipped with the back hanger.Be used for being connected with spring plate on the car.
Remarkable result of the present utility model is: girder and the stitch welding of secondary beam back heavy connect has strengthened the vehicle frame weight capacity, and the crook is not easy fracture behind the girder, and the reinforcement of back hanger holding capacity has improved vehicle frame service life, reduce vehicle frame manufacturing cost and difficulty, also guaranteed all stressed integraty of primary and secondary beam.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
As Fig. 1, the whole twin beams vehicle frame of a kind of tritruck shown in Figure 2, by girder 1, secondary beam 2, be responsible for 3, connecting box 4, fuel tank seat support beam 5, front cross rail 6, hinge of leaf spring mounting pipe 7, preceding hanger 8 and back hanger 9 are formed, wherein secondary beam 2 is arranged on the top of girder 1 middle part to the rear portion, the front end of described secondary beam 2 is connected with the rear end of fuel tank seat support beam 5 by front cross rail 6, the front end of described fuel tank seat support beam 5 is connected with the person in charge 3, described fuel tank seat support beam 5 be responsible for 3 and be connected with an end of described girder 1 by connecting box 4, the middle part of this girder 1 is from bottom to top from inside to outside gradually near secondary beam 2, these secondary beam 2 afterbodys extend back, the extension of this secondary beam 2 abuts in the rear horizontal section of described girder 1, aligns with girder 1 rear end in the rear end of described secondary beam 2.
As shown in Figure 1, the bilateral symmetry of the whole twin beams vehicle frame of tritruck is distributed with girder 1 and secondary beam 2, is horizontally arranged with hinge of leaf spring mounting pipe 7 in tricycle frame.As shown in Figure 2, the end of hinge of leaf spring mounting pipe 7 is installed in the crevice place between girder 1 and the secondary beam 2, and welds with contiguous block 10 and girder 1 and secondary beam 2.
The end of described hinge of leaf spring mounting pipe 7 is equipped with preceding hanger 8, and the rear portion of described girder 1 is equipped with back hanger 9.
