Abstract

The invention discloses a double-rear-axle truck frame and relates to the technical field of automobile manufacture. The truck frame is divided into a front section, a transition section and a left vertical beam and a right vertical beam which are arranged on the rear section. The outside distance between the left vertical beam and the right vertical beam in the front section is 1080 mm, and the outside distance between the left vertical beam and the right vertical beam in the rear section is 850 mm. A front cover plate and an engine front suspension bend beam are sequentially arranged on the front section, and a first middle beam, a second middle beam, a balance suspension beam and a rear beam are sequentially arranged on the rear section. Two ends of the engine front suspension bend beam are connected with a middle support to be further connected with the left vertical beam and the right vertical beam through plate spring seats. Two ends of the first middle beam, the second middle beam, the balance suspension beam and the rear beam are connected with the left vertical beam and the right vertical beam through connection plates. The truck frame solves the problem that the existing frame is high in mass, low in loading mass and poor in whole truck fuel economy.

Technical field
The present invention relates to field of automobile, especially a kind of vehicle frame for heavy-duty cargo truck.
Background technology
Automobile chassis frame is the basic component of automobile, traditional automobile chassis frame is two back axle truck frame particularly, the left and right longeron of general employing, left and right longitudinal beam reinforcing plate and some riveting transverse beams or bolt connect and compose loading chassis, each to driving engine, operator's compartment etc. principal assembly is connected in aggregates, this vehicle frame generally all does orthogonal or trapezoidal, is arranged in vehicle body bottommost; Heavy-duty automobile frame is as the substrate of car load and main stressed member, it is the carrier connecting other assemblies and parts, in use not only to bear the weight load of various device, also to bear the various load from automobile interior exterior, and the impact load of the road complexity caused such as concavo-convex, bending.Prior art heavy vehicle frame is primarily of two longerons, two longitudinal beam reinforcing plates and several crossbeam composition, and mainly consider bending strength and torsional strength during design, moment of deflection is mainly born by longeron and crossbeam.The vehicle frame of the two back axle HD truck of prior art is in order to ensure bending strength and torsional strength, and vehicle frame entirety is done larger, and cause because complete vehicle quality is large and cause fuel economy poor, loading mass is few.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of two back axle truck frame, and it is large that it can solve automobile chassis frame total quality, causes the problem that car load fuel economy is poor and loading mass is few.
In order to solve the problem, technical scheme of the present invention is: this pair of back axle truck frame, includes left longeron and right vertical beam, and described left longeron and described right vertical beam are divided into three sections: leading portion, transition phase and back segment; Described in described leading portion, between left longeron and described right vertical beam, outer lateral extent is D, D=1080 millimeter; Described in described back segment, between left longeron and described right vertical beam, outer lateral extent is d, d=850 millimeter, connects described back segment after connecing described leading portion before described transition phase; Described leading portion is disposed with front shrouding, engine front overhang camber beam; Described back segment is disposed with the first intermediate transverse girder, the second intermediate transverse girder, equalizing suspension system crossbeam and after cross member; Described front shrouding two ends are put bearing by cabin front suspension and are connected with left longeron and right vertical beam respectively; Be connected with left longeron and right vertical beam respectively by spring block again after described engine front overhang camber beam two ends are connected with midship mounting; Described first intermediate transverse girder, the second intermediate transverse girder and equalizing suspension system crossbeam are all connected with left longeron and right vertical beam by connecting panel respectively with after cross member two ends.
In technique scheme, more specifically scheme can also be: described left longeron and right vertical beam are 8 millimeters thick, and it is highly H that the steel plate that yield limit is greater than 700MPa is made, top airfoil width is A, and lower aerofoil width is the trough girder of B, wherein: H=282 millimeter, A=80 millimeter, B=85 millimeter; Described first intermediate transverse girder, the second intermediate transverse girder, equalizing suspension system crossbeam and after cross member are the trench structure steel that yield limit is greater than 700MPa; Described connecting panel is the L-type structural steel that yield limit is greater than 700MPa.
Owing to adopting technique scheme, the present invention has following beneficial effect:
1. vehicle frame is pincer structure, wide 1080 millimeters outside front end, wide 850 millimeters or 860 millimeters outside rear end, can meet the arrangement requirement of high-powered engine, large scale water tank etc., and ensure the general of other systematic part.
2. chassis side rail adopts 8 millimeters thick, and it is highly 282 millimeters that the steel plate that yield limit is greater than 700MPa is made, and top airfoil width is 80 millimeters, and lower aerofoil width is the trough girder of 85, and bending resistant section coefficient is large, and intensity is good.
3. the steel plate that intermediate transverse girder, equalizing suspension system crossbeam, after cross member adopt yield limit to be greater than 700MPa is made, and trench structure, structure is simple, and lightweight, intensity is high.
4. the steel plate that connecting panel adopts yield limit to be greater than 700MPa is made, L-type structure, and structure is simple, and lightweight, intensity is high.
5. owing to adopting advanced method to be optimized design, and R. concomitans high strength material, side rail inner brace panel can be cancelled, reduce crossbeam and connecting panel thickness, frame assembly weight amounts to and reduces about 250kg, effectively can improve the problem that fuel economy is poor and loading mass is few.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is birds-eye view of the present invention.
Fig. 3 is longeron cross-sectional structure schematic diagram of the present invention.
Number in the figure is expressed as: 1, left longeron; 2, right vertical beam; 3, front shrouding; 4, engine front overhang camber beam; 5, the first intermediate transverse girder; 6, the second intermediate transverse girder; 7, equalizing suspension system crossbeam; 8, after cross member; 9, connecting panel; 10, cabin front suspension puts bearing; 11, spring block; 12, midship mounting.
