Abstract
The utility model concretely discloses a heavy vehicle high-strength single layer vehicle frame assembly. The vehicle frame assembly comprises single layer longitudinal beams, transverse beams, and reinforcing plates, the whole vehicle frame assembly is in a front-wideness back-narrowness structure, hole positions of the vehicle frame longitudinal beams are characterized by design of a standard pitch, the front end of the vehicle frame assembly is provided with an integral front suspension combination support and a transverse beam, large-span transverse beam connecting plates and a local reinforcing structure are adopted for the vehicle frame assembly, ''L''-shaped large-span reinforcing plates are disposed at the upper part of the vehicle frame assembly, and an integral tail transverse beam is adopted for the tail part of the vehicle assembly. The beneficial effects of the heavy vehicle high-strength single layer vehicle frame assembly are: high strength, light weight, good universality, weight reduction by about 150kg under the condition of guaranteeing bearing capability compared with a double layer vehicle frame, etc.
Description
Technical field
The utility model relates to a kind of heavy-duty automobile frame assembly, belongs to vehicle key parts technical field.
Background technology
Heavy-duty automobile frame weight accounts for about 10% of complete vehicle curb weight, and exploitation lightweight vehicle frame is significant for reducing complete vehicle curb weight.Present heavy-duty automobile frame longeron is many to be comprised of two-layer grooved steel plate, even if the individual layer vehicle frame is arranged, also only is the vehicle frame strength beam of cancelling wherein, and frame strength can not be guaranteed.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of heavy motor vehicle high strength individual layer frame assembly, satisfies the designing requirement of lightweight High Performance tractor truck.
The utility model adopts following technical scheme:
A kind of heavy motor vehicle high strength individual layer frame assembly, described frame assembly comprises individual layer longeron, crossbeam and brace panel, the integral structure of frame assembly is front wide and rear narrow structure, the standard hole pitch design is adopted in position, described chassis side rail hole, " L " shape large span brace panel is installed on described frame assembly top, and described frame assembly afterbody adopts integrated tail cross beam.
Described chassis side rail adopts the high strength steel of tensile strength 850MPa, yield limit 700MPa.
Described frame assembly front end is installed integral type front-suspension combined bracket and crossbeam.
Frame assembly adopts position, chassis side rail hole to adopt the standard hole pitch design, is conducive to the modular arrangement of each assembly.
Frame assembly adopts the chassis side rail front end that integral type front-suspension combined bracket and crossbeam are installed, and the anterior rigidity of vehicle frame is significantly improved, and has improved simultaneously the reliability of engine mounting and Cab mounting.
Frame assembly adopts long-span beam connecting panel and partial reinforced structure, and materials are economized, and distribution of stress is more even.
Frame assembly adopts integrated tail cross beam, and is simple and reliable.
" L " shape large span brace panel, Effective Raise vehicle frame bending strength are installed in frame assembly top.
The beneficial effects of the utility model are to have the advantages such as intensity is high, lightweight, commonality is good, and heavily approximately 150kg falls in more double-deck vehicle frame under the condition that guarantees load-carrying capacity.

Fig. 2 is long-span beam assembly schematic diagram;
Wherein, 1. integral type front-suspension combined bracket 2. front end cross beams 3. chassis side raiies 4. first crossbeam assemblies 5. second cross beam assemblies 6. brace panels 7. casting beam assemblies 8. integrated tail cross beams 9. cross-beam bodies 10. cross-beam connecting plates.
The specific embodiment
Comprise such as Fig. 1 heavy motor vehicle high strength shown in Figure 2 individual layer frame assembly: integral type front-suspension combined bracket 1, front end cross beam 2, chassis side rail 3, first crossbeam assembly 4, second cross beam assembly 5, brace panel 6, casting beam assembly 7, integrated tail cross beam 8, cross-beam body 9, cross-beam connecting plate 10.
As shown in Figure 1, totally two of chassis side raiies 3 are shaped as grooved, the structure left-right symmetric, left-right longeron is linked together by crossbeam, and material is the high strength steel of tensile strength 850MPa, yield limit 700MPa, makes frame assembly present front wide and rear narrow shape by bending technique.Integral type front-suspension combined bracket 1 and front end cross beam 2 are bolted in chassis side rail anterior, and wherein the integral type front-suspension combined bracket integrates steering box machine support, operator's compartment load lifting cylinder support, Cab mounting, front plate spring shackle bracket, driver's cab turnover bracing strut, intercooler tank bracket, front haulage hook seat and front bumper bracket.First crossbeam assembly 4, second cross beam assembly 5 and casting beam assembly 7 all have the long-span beam connecting panel, be fixed between the left-right longeron by rivet and bolt respectively, to strengthen the vehicle frame torsional strength, wherein the connecting panel of the connecting panel of second cross beam assembly 5 and casting beam assembly 7 has overlappingly, plays local booster action.Large span brace panel 6 sections are L-shaped, are connected in the vehicle frame upper back by rivet and bolt, have two crossbeams, large span brace panel 6 to play the effect that improves the vehicle frame bending strength in the middle of the brace panel of the left and right sides.Integrated tail cross beam 8 is only formed by a block plate bending, is bolted in the vehicle frame afterbody.The longitudinal pitch of chassis side rail middle part and rear orifice adopts the standard hole pitch design, and pitch of holes is 50mm and multiple thereof.
Fig. 2 is the enlarged diagram of second cross beam assembly 5, and second cross beam assembly 5 mainly is comprised of cross-beam body 94 cross-beam connecting plates 10 similar with shape totally, and cross-beam connecting plate 10 spans are large, make the vehicle frame distribution of stress more even.
