Description

The HD truck vehicle frame
Technical field
The utility model relates to field of automobile, especially a kind of vehicle frame for the heavy duty truck.
Background technology
Automobile chassis frame is the basic component of car chassis and automobile, traditional automobile chassis frame is the HD truck vehicle frame particularly, generally be to adopt chassis frame and body construction, namely adopt the riveted joint of left and right longeron and some crossbeams or welding to constitute the load-carrying chassis, connect driving engine, each principal assembly in aggregates, this vehicle frame all is rectangle or trapezoidal generally, is arranged in the bottommost of vehicle body, above a lot of horizontal longerons constitute a rectangular configuration; The heavy motor vehicle vehicle frame is the carrier that is connected other assemblies and parts as the substrate of car load with main stressed member, in use not only to bear various device load, also to bear from the various load inside and outside the car, and the impact load of the concavo-convex complexity that causes of road.Prior art heavy goods vehicles vehicle frame mainly is made up of with crossbeam two longerons and number, considers mainly during design that bending strength and torsional strength, moment of deflection mainly are to be born by longeron, and twist moment is mainly born by longeron and crossbeam.The vehicle frame of prior art heavy motor vehicle is in order to guarantee bending strength and torsional strength, and vehicle frame integral body is done greatlyyer, causes because of quality to cause the car load fuel economy poor greatly.
The utility model content
Technical problem to be solved in the utility model provides a kind of HD truck vehicle frame, and it is big that it can solve the automobile chassis frame total quality, causes the problem of car load fuel economy difference.
In order to address the above problem, the technical solution of the utility model is: this HD truck vehicle frame includes left longeron, right vertical beam, front cross rail, intermediate transverse girder, equalizing suspension system crossbeam and transom beam; Described left longeron and described intermediate transverse girder, the connection of equalizing suspension system crossbeam all connects by connecting panel; Described right vertical beam and described intermediate transverse girder, the connection of equalizing suspension system crossbeam all connects by connecting panel; Described left longeron connected by fastener with being connected all of described front cross rail and transom beam, and described right vertical beam connected by fastener with being connected all of described front cross rail and transom beam.
In the technique scheme, more specifically scheme can also be: wide before the described HD truck vehicle frame is D, the D=940 millimeter, and the back is wide to be d, the d=810 millimeter.
Further: 8 millimeters thick are adopted at the middle part of described left longeron and right vertical beam, and yield strength is made greater than the steel plate of 750MPa and highly is H, and width is the beam of the flute profile of E, wherein: H=273 millimeter, E=90 millimeter; Described front cross rail, intermediate transverse girder, the middle part of equalizing suspension system crossbeam and transom beam is flute profile.
Owing to adopt technique scheme, the utlity model has following beneficial effect:
1, frame assembly is preceding wide 940 millimeters, and the back is wide 810 millimeters, can effectively satisfy the general of car load layout and other system zero parts.
2, chassis side rail is that 8 millimeters thick are adopted at the middle part, and it highly is 273 millimeters that yield strength is made greater than the steel plate of 750MPa, and width is the beam of 90 millimeters flute profile, and the bending resistant section coefficient is big.
3, crossbeam adopts yield strength to make greater than the steel plate of 750MPa, and trench structure is simple in structure, the commonality height, and weight is lighter.
4, because the advanced method of employing is optimized design, and in conjunction with new material, the longeron brace panel can significantly shorten and attenuate, length foreshortens to 1500 millimeters by 4780 millimeters, thickness is thinned to 4 millimeters by 5 millimeters, and frame assembly weight amounts to and reduces about 200 kilograms, can effectively improve fuel economy.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is the utility model birds-eye view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
HD truck vehicle frame illustrated in figures 1 and 2 includes left longeron 8, right vertical beam 2, front cross rail 1, intermediate transverse girder 3, intermediate transverse girder 4, equalizing suspension system crossbeam 5 and transom beam 6; Front cross rail 1, intermediate transverse girder 3, the middle part of equalizing suspension system crossbeam 5 and transom beam 6 is flute profile; Left side longeron 8 and intermediate transverse girder 3, intermediate transverse girder 4, equalizing suspension system crossbeam 5 all connect by connecting panel 7; Right vertical beam 2 and intermediate transverse girder 3, intermediate transverse girder 4, equalizing suspension system crossbeam 5 all connect by connecting panel 7; Connecting panel 7 was bolted to connection with being connected with connecting panel 7 and being connected all of right vertical beam 2 of left longeron 8;
Left side longeron 8 all is bolted to connection with front cross rail 1 and transom beam 6; Right vertical beam 2 all is bolted to connection with front cross rail 1 and transom beam 6.
Left side longeron 8 and right vertical beam 2 are the middle part and adopt 8 millimeters thick, and yield strength is made greater than the 750L steel plate of 750MPa and highly is H, and width is the beam of the flute profile of E, wherein: H=273 millimeter, E=90 millimeter;
Front cross rail 1, intermediate transverse girder 3, intermediate transverse girder 4, equalizing suspension system crossbeam 5 and transom beam 6 all adopt yield strength to form greater than the 750L steel plate compacting of 750MPa, and be simple in structure, the commonality height, and weight is lighter.
Wide before the HD truck vehicle frame is D, the D=940 millimeter, and the back is wide to be d, the d=810 millimeter can effectively satisfy the general of car load layout and other system zero parts.
