Abstract
The utility model discloses a frame structure with a wide front part and a narrow back part for a heavy truck, which is used for solving the problem that the frame of the heavy truck cannot be widened unrestrictedly for adapting to the installation of parts such as cabs, engines, water tanks and the like. The frame structure with the wide front part and the narrow back part for the heavy truck comprises a right longitudinal beam assembly, a left longitudinal beam assembly, a middle transverse beam and a tail transverse beam, wherein the longitudinal beam assemblies of the frame are connected with the transverse beam through bolts or rivets; a structure of which the front part is wide and the back part is narrow is adopted for the frame; the width of a front end is 930-950 millimeters; the width of a back end is 770-790 millimeters; and the structure becomes narrow linearly from a range of 930-960 millimeters away from the foremost end of the frame, and stops becoming narrowing from a range of 1,700-1,750 millimeters away from the foremost end of the frame. The frame structure with the wide front part and the narrow back part for the heavy truck has the beneficial effects that: the problem of difficulty in installing parts such as cabs, engines, water tanks and the like is solved under the condition of ensuring that the width of the entire truck is accordant with the specifications, and technological bases are provided for the comfort of the entire truck.
Description
Invention field
The utility model relates to the heavy motor vehicle vehicle frame mechanism, specially refers to the front wide and rear narrow body frame structure for automotive of heavy motor vehicle.
Background technology
The arrangement of prior art heavy motor vehicle generally is the type of drive that adopts engine behind front wheel, and under the increasing situation of driving engine profile, power, the water tank size that needs also can correspondingly increase, and the installation dimension of operator's compartment also can strengthen.Usually, the operator's compartment of heavy motor vehicle, driving engine and water tank are installed in the front portion of vehicle frame, vehicle frame need be widened, to adapt to the installation of above-mentioned parts.But the car load width of heavy motor vehicle is subjected to specification limits, can not be for parts such as operator's compartment, driving engine and water tank, the unconfined unitized frame of widening are installed.
Summary of the invention
Can not unconfinedly widen to adapt to the problem of parts such as operator's compartment, driving engine and water tank are installed for solving the heavy motor vehicle vehicle frame, the utility model proposes the front wide and rear narrow body frame structure for automotive of a kind of heavy motor vehicle.The front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle comprises right vertical beam assembly, left longeron assembly, front cross rail, intermediate transverse girder and transom beam; The chassis side rail assembly is connected by bolt or rivet with crossbeam; Vehicle frame adopts front wide and rear narrow structure; Wherein, the front end width is 930～950mm, rear end width 770～790mm, by the distance vehicle frame foremost in 930～960mm scope the beginning straight line narrow down, to stopping narrowing down in 1700～1750mm scope foremost apart from vehicle frame.
Further, the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle, longeron assembly are that section height is that 230～325mm, thickness are 5～10mm, the yield strength big beam slab greater than 400 MPa.
Further, the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle, the front overhang length of vehicle frame is 1100～1370mm, and wheelbase is 3220～4900mm, and rear overhang length is 1300～2900mm, and the aerofoil width of vehicle frame is 75～85mm.
The useful technique effect of the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle is to guarantee that the car load width meets under the situation of standard, solved the problem that parts difficulties such as operator's compartment, driving engine and water tank are installed, for the car load traveling comfort provides technical foundation.
Description of drawings
Accompanying drawing 1 is the schematic top plan view of the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle.
Below in conjunction with drawings and the specific embodiments the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle is further described.
The specific embodiment
Accompanying drawing 1 is the schematic top plan view of the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle, and among the figure, 1 is left longeron assembly, and 2 is the right vertical beam assembly, and 3 is front cross rail, and 4 is intermediate transverse girder, and 5 is transom beam.As seen from the figure, the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle comprises left longeron assembly 1, right vertical beam assembly 2, front cross rail 3, intermediate transverse girder 4 and transom beam 5; The chassis side rail assembly is connected by bolt or rivet with crossbeam; Vehicle frame adopts front wide and rear narrow structure; Wherein, the front end width is 930～950mm, rear end width 770～790mm, from the distance vehicle frame foremost in 930～960mm scope the beginning straight line narrow down, to stopping narrowing down in 1700～1750mm scope foremost apart from vehicle frame.In the embodiment shown in Figure 1, vehicle frame front end width is 940 mm, and the rear end width is 780mm, from the distance vehicle frame foremost 955mm beginning straight line narrow down, to apart from vehicle frame foremost the termination of 1715mm place narrow down.
Be to guarantee frame strength and rigidity, the longeron assembly of the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle is that section height is that 230～325mm, thickness are 5～10mm, the yield strength big beam slab greater than 400 MPa.And the front overhang length of vehicle frame is 1100～1370mm, and wheelbase is 3220～4900mm, and rear overhang length is 1300～2900mm, and the aerofoil width of vehicle frame is 75～85mm.
Obviously, through above improvement, the front wide and rear narrow body frame structure for automotive of the utility model heavy motor vehicle can solve the problem that parts difficulties such as operator's compartment, driving engine and water tank are installed, for the car load traveling comfort provides technical foundation guaranteeing that the car load width meets under the situation of standard.
