Abstract
The utility model relates to a connection structure for longitudinal beams and a cross beam of a car frame. The connection structure comprises a left outer longitudinal beam, a right outer longitudinal beam, a left inner longitudinal beam, a right inner longitudinal beam, a left trough type bracket and a right trough type bracket, wherein the left outer longitudinal beam and the left inner longitudinal beam are arranged vertically and connected with each other; the right outer longitudinal beam and the right inner longitudinal beam are arranged vertically and connected with each other; the left outer longitudinal beam is connected with the cross beam through the left trough type bracket; and the right outer longitudinal beam is connected with the cross beam through the right trough type bracket. Compared with the prior art, the connection structure has the advantages of rationality in load distribution, low cost and the like.
Description
Technical field
The utility model relates to a kind of passenger vehicle accessory, especially relates to the draw bail of a kind of chassis side rail and crossbeam.
Background technology
At present, because passenger vehicle exists usage condition to differ greatly, vehicle frame working condition and stressing conditions be abominable (particularly rear leaf spring place) relatively, often adopts double-deck crossbeam form (promptly inside and outside girder work) mostly, improves frame strength with crossbeam in upper and lower aerofoil perforate riveted joint then.
Owing to adopt double-deck crossbeam version (outside channel girder work promptly) to exist complete vehicle weight to increase; Simultaneously because complicated factors such as power/moment that the longeron lower aerofoil bears and live loads, perforate causes shortcomings such as local performance weakening.
Summary of the invention
The purpose of this utility model is exactly that a kind of distribution of load is reasonable, cost the is low chassis side rail and the draw bail of crossbeam are provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: the draw bail of a kind of chassis side rail and crossbeam, comprise left exterior beam, right exterior beam, left interior beam, right interior beam, described left exterior beam is connected with left interior beam upper and lower settings, described right exterior beam is connected with right interior beam upper and lower settings, it is characterized in that, also comprise left troffer and right troffer, described left exterior beam connects crossbeam by left troffer, and described right exterior beam connects crossbeam by right troffer.
The outside of belly of described left exterior beam, right exterior beam is offered riveted holes, rivets with left troffer and right troffer respectively by rivet.
Described left troffer and right troffer and crossbeam riveted joint or welding.
Be provided with spring carrier in described left troffer and the right troffer.
Compared with prior art, the utlity model has following advantage:
One, distribution of load is reasonable: former scheme only relies on enough intensity to resist the generation of inefficacy.Existing technology realizes intensity and the suffered load of the unified decomposition of rigidity; Guaranteeing under the suitable intensity condition, also also reducing the fugitiveness that produces because of operation conditions change when certain elastic deformation is eliminated load, improving the corresponding traveling comfort of taking by producing.Two, cost-cutting: under the condition that guarantees automobile reliability, alleviate the car load deadweight, reduced consumption.
Two, go up lower aerofoil at the chassis side rail (bathtub construction) of this type structure and reduce perforate, improved the channel-section force-bearing situation.
Three, has certain generalization: can consider to adopt this structure at the structure design of this type later.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-left side exterior beam, the right exterior beam of 2-, 3-crossbeam, 4-left side troffer, the right troffer of 5-, 6-left plate spring bracket, the right spring carrier of 7-.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment 1
As shown in Figure 1, the draw bail of a kind of chassis side rail and crossbeam, comprise left exterior beam 1, right exterior beam 2, left side interior beam, right interior beam, described left exterior beam 1 below is provided with connected left interior beam, described right exterior beam 2 belows are provided with connected right interior beam, also comprise left troffer 4 and right troffer 5, the outside of belly of described left exterior beam 1 is offered riveted holes, connect left troffer 4 by rivet, left side troffer 4 and crossbeam 3 riveted joints, the outside of belly of described right exterior beam 2 is offered riveted holes, connects right troffer 5 by rivet, right troffer 5 and crossbeam 3 riveted joints.
Be provided with left plate spring bracket 6 in the described left troffer 4, be provided with right spring carrier 7 in the right troffer 5.
The utility model connecting mode be adopt part left and right sides exterior beam and left and right sides troffer the outside of belly at a certain distance, the quantity perforate rivets, close with crossbeam riveting (weldering) by left and right sides troffer then to connect (the spring carrier riveted is in the troffer scope).
The utility model adopts the unification of frame strength and rigidity.Under the condition that keeps suitable intensity, realize its rigidity property.Reach car load under different driving conditions, satisfy the unification of bending, turn round load performance; Alleviate complete vehicle weight simultaneously.
The utility model principle of work: be delivered to the tire antagonistic force to vehicle bridge to steel spring again through ground, by the steel spring bearing load (power/moment) is passed to the vehicle frame left-right longeron, former mode of operation connects with exterior beam by left and right sides interior beam, connect with crossbeam again and form framed structure, the decomposition of realization load; This force-bearing situation is gone up largely and is relied on vehicle frame self intensity opposing inefficacy, because lower aerofoil perforate on chassis side rail easily causes local performance to reduce.And novel connecting mode adopts left and right sides exterior beam and troffer riveted and crossbeam riveting (weldering) after outside of belly perforate to close, and can possess corresponding rigidity under assurance suitable intensity condition like this; Suffered load passes to the vehicle frame left-right longeron by the steel spring bearing, is delivered to crossbeam forming framed structure by troffer, under the condition that guarantees certain intensity, realizes decomposing load simultaneously; Because longitudinal and transverse beam and a certain amount of elastic deformation of the corresponding generation of troffer are eliminated part load; And reduce perforate at last lower aerofoil, improved the stress form of flute profile longeron, reduced because of the not enough crackle inefficacy that produces of the local performance of longeron.
