The invention discloses a heavy lorry frame, and relates to the technical field of automobile manufacture. The heavy lorry frame comprises a left longitudinal beam, a right longitudinal beam, a front transverse beam, a middle transverse beam, a balanced suspension transverse beam and a tail transverse beam, the left longitudinal beam is connected with the middle transverse beam and the balanced suspension transverse beam through connection plates, the right longitudinal beam is connected with the middle transverse beam and the balanced suspension transverse beam through connection plates, the left longitudinal beam is connected with the front transverse beam and the tail transverse beam through fasteners, and the right longitudinal beam is connected with the front transverse beam and the tail transverse beam through fasteners. The front width D of the heavy lorry frame is 940 millimeters, and the rear width d of the heavy lorry frame is 810 millimeters. The heavy lorry frame can solve the problems that fuel economy of a whole lorry is poor as a whole lorry frame is heavy.
Description
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 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 left and right longeron and some riveting transverse beams or welding to consist of loading 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 transverse and longitudinal beam consist of a rectangular configuration; Heavy-duty automobile frame is the carrier that connects other assemblies and parts as the substrate of car load with the stressed member of being connected, 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.The prior art heavy vehicle frame mainly is comprised 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 greatlyr, causes because of quality to cause greatly the car load fuel economy poor.
Summary of the invention
Technical matters to be solved by this invention provides a kind of HD truck vehicle frame, and it is large that it can solve the automobile chassis frame total quality, causes the poor problem of car load fuel economy.
In order to address the above problem, technical scheme of the present invention 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 and described front cross rail are connected with transom beam to be connected all and are connected by fastener, and described right vertical beam is connected with transom beam to be connected all with described front cross rail and is connected by fastener.
In the technique scheme, more specifically scheme can also be: widely before the described HD truck vehicle frame be D, the D=940 millimeter, rear wide 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.
Because adopt technique scheme, the present invention has following beneficial effect:
1, frame assembly is front wide 940 millimeters, and is rear wide 810 millimeters, but to satisfy effectively arrangement and other system parts is general.
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 large.
3, crossbeam adopts yield strength to make greater than the steel plate of 750MPa, trench structure, and simple in structure, commonality is high, and weight is lighter.
4, because the advanced method of employing is optimized design, and in conjunction with new material, longitudinal beam reinforcing plate 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 approximately 200 kilograms, but the Effective Raise fuel economy.
Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is birds-eye view of the present invention.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
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 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; Being connected to be connected with connecting panel of connecting panel 7 and left longeron 8 was bolted to connection with being connected all of right vertical beam 2;
Left 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 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 simple in structure, commonality is high, and weight is lighter.
Wide before the HD truck vehicle frame is D, the D=940 millimeter, rear wide be d, the d=810 millimeter, but to satisfy effectively arrangement and other system parts is general.
