Abstract
The utility model relates to frame structures of heavy-duty trucks, in particular to a modified integral frame assembly of a heavy-duty truck, which is characterized in that a front beam, a plurality of transverse beams and a tail beam are respectively welded between a left longitudinal beam and a right longitudinal beam, sections of the left longitudinal beam and the right longitudinal beam are box type I-beams, the front beam is a tubular beam, each transverse beam is composed of a plurality of tubular beams and rectangular beams at intervals, the tail beam is a transversely arranged V-beam, each I-beam is in an integral box structure formed by welding an upper wing plate, a lower wing plate, a left web and a right web, and a reinforcing plate is arranged in each V-beam. Implementing the integral frame according to the scheme enhances overall rigidity of the frame and reduces ventral height and centroid height of the frame, so that stability of trucks is enhanced. The left longitudinal beam and the right longitudinal beam of the frame are in box I-shaped welded structures, the beams of the frame are provided with tubular and rectangular sections, and thereby enhancement on torsion resisting stiffness of the frame is benefited. The modified integral frame assembly is simple and reasonable in structure and effective and beneficial in modification.
Description
Technical field
The utility model relates to the structure of heavy motor vehicle vehicle frame, especially about the improved integral type vehicle frame of a kind of heavy motor vehicle assembly.
Background technology
At present, have railway carriage and shelter etc. go up assembling device in, heavy motor vehicle, the structure of its vehicle frame is the structural shape that main car frame adds subframe.Adopt connecting panel between the major and minor vehicle frame and is connected with saddle clamp by bolt, therefore, cause the frame assembly total quality bigger, and the ground-surface height of plan range is higher on the vehicle frame, the car load height of center of mass of going up after adorning is also higher thereupon when carrying.The frame assembly of this structure, in use, the relative rigidity of major and minor vehicle frame is less, easily produces torsional deflection, and the bolt and the also damage easily of saddle clamp that are used to connect major and minor vehicle frame.
The utility model content
The purpose of this utility model is to have heavy motor vehicle now because of the defective in the major and minor vehicle frame interconnection system structure for overcoming, and proposes a kind of improved integral type vehicle frame assembly.For realizing this purpose, the technical scheme that adopts is: the improved integral type vehicle frame of a kind of heavy motor vehicle assembly, it is characterized in that being welded with respectively between the left and right longeron front-axle beam, many crossbeams and tail boom, the cross section of left and right longeron is made as box " worker " word beam, front-axle beam is the pipe beam, crossbeam is made up of some pipe beams and rectangular tube distance between girders, tail boom is made as horizontal " V " ellbeam, " worker " word beam is provided with brace panel by the be welded as a whole box-structure of formula of last lower wing plate and left and right sides web in " V " ellbeam.
Press the integral type vehicle frame assembly that this programme is implemented,, compare, under equal in quality, improved the vehicle frame integral rigidity with original design owing to just be improved to by the integral structure that welds through bolt combination bonded assembly frame assembly with former; Under same stiffness, reduced the outside of belly height and the vehicle frame height of center of mass of vehicle frame, therefore increased the stability of vehicle.The left and right longeron of vehicle frame adopts the welded structure of box " worker " font, not only avoided the demand of large stamping die, and easily realize the change outside of belly height of vehicle frame and the structure design of change frame width, be of value to and satisfy vehicle the different designing requirement of frame assembly different parts width.Cross member of frame adopts tubulose and square-section, and being of value to increases the vehicle frame torsional rigidity.The utility model structure is simple and direct rationally, is a kind of effective and useful improvement.
Description of drawings
Fig. 1 is the surface structure scheme drawing of a kind of embodiment of the utility model;
Fig. 2 is the cross section structure scheme drawing of left and right longeron among Fig. 1;
Fig. 3 is the structural representation of front-axle beam and tubular crossbeam among Fig. 1;
Fig. 4 is the structural representation of rectangular tube crossbeam among Fig. 1;
Fig. 5 is the structural representation of horizontal among Fig. 1 " V " ellbeam.
The specific embodiment
Be described in further detail in conjunction with the accompanying drawings.The frame assembly of showing among Fig. 1 is respectively arranged with 3,2 tubular type crossbeams 4 of tubular type front-axle beam and 1 tubular type crossbeam 6 and 7,2 rectangular tube crossbeams 5 of 2 tubular type crossbeams and horizontal " V " shape tail boom 8 between left and right longeron 1 and 2, make front-axle beam 3, each crossbeam 4,5,6,7 and tail boom 8 and left and right longeron 1,2 constitute integral type vehicle frame assembly through welding.Wherein, left and right longeron 1,2 is pulled 11 (21) box beam that are welded into " worker " font by upper flange 12 (22), lower wing plate 13 (23) and left and right abdomen, and 8 of tail booms are welded with 2 brace panels 81 in " V " shape plate that is pressed into, to increase the rigidity of tail boom.The box beam structure of " worker " font has not only been avoided the demand of large stamping die, and realizes the change outside of belly height of vehicle frame and the structure design of change frame width easily, is of value to and satisfies vehicle to the different designing requirement of frame assembly different parts width; Cross member of frame adopts tubulose and square-section, has increased the vehicle frame torsional rigidity significantly.
Upper flange or left and right abdomen at left and right longeron are pulled by bolt and the relevant assembly parts connection with operator's compartment, driving engine, change-speed box, part-time case etc. of relevant connection support.
The lower wing plate of left and right longeron or left and right web connect by bolt and the relevant assembly parts with vehicle bridge and suspension system etc. of relevant connection support.
Claims (3)
1. the improved integral type vehicle frame of heavy motor vehicle assembly, comprise left-right longeron, front-axle beam, crossbeam and tail boom, it is characterized in that being welded with respectively between the left and right longeron front-axle beam, many crossbeams and tail boom, the cross section of left and right longeron is made as box " worker " word beam, front-axle beam is the pipe beam, crossbeam is made up of some pipe beams and rectangular tube distance between girders, and tail boom is made as horizontal " V " ellbeam.
2. by the improved integral type vehicle frame of the described heavy motor vehicle of claim 1 assembly, it is characterized in that " worker " word beam is by the be welded as a whole box-structure of formula of last lower wing plate and left and right sides web.
