Abstract
The utility model relates to an auxiliary frame, which comprises a left extension longitudinal beam and a right extension longitudinal beam tightly connected with a main longitudinal beam of the frame, wherein the cross sections of the fastening ends of the left extension longitudinal beam and the right extension longitudinal beam connected with the main frame longitudinal beam are matched with the cross section of the main frame longitudinal beam; and the upper surfaces of the free ends of the left extension longitudinal beam and the right extension longitudinal beam are in the same plane that is lower than the plane in which the main frame longitudinal beam is located. With the adoption of the auxiliary frame, the manufacturing process is simple, the installation is convenient, the cost is low, the defect that the integral frame is difficultly shaped is overcame, the height of a cab is effectively decreased to improve the stability of the whole vehicle and the comfortableness of a man and a machine, more decrease of the front end can be simply realized than the back end, no obvious drawing damage and distortion can be caused, and the intensity and the dimension of a frame assembly are not affected, thereby avoiding the phenomenon of the deviation of an automobile during the driving caused by the integral shaped structure of the frame; moreover, the deformation of the automobile caused by the cab can be realized in different widths, therefore, the mouldability-extension requirements of a model platform can be greatly improved.
Description
Technical field
The utility model relates to the body frame structure for automotive field, specifically, relates to a kind of subframe.
Background technology
The vehicle frame of light-duty commercial truck is independent bearing formula vehicle frame on the automotive market at present, and chassis side rail is an one-piece construction; For improving the handling stability energy of car load, the center of gravity of car load answers design-calculated low as far as possible.For reducing the operator's compartment setting height(from bottom), traditional vehicle frame longitudinal beam front section generally is designed to low early and high after variable section structure; But because chassis side rail sheet material thicker (general 4 ~ 8mm) and tensile strength higher (more than the 440Mpa), the changes of section diff-H is (100mm is following) too greatly, otherwise chassis side rail is made the moulding meeting and tangible drawing crack occurred, pull and torsional deflection, have a strong impact on the intensity and the size of frame assembly, the running car sideslip can occur when serious.Simultaneously, along with the raising of people's living standard, client requires also more and more higher to the man-machine comfort level of car load, driver requestedly gets on or off the bus more easily.People urgently wish to design a kind of subframe for this reason, solve vehicle frame and make structure problem, reduce cab heights, improve whole vehicle stability and man-machine traveling comfort.
The utility model content
At the problems referred to above, the utility model provides a kind of subframe, has overcome the unit frame longeron and has made forming defect, has enlarged the car load bodywork height scope that downgrades.
Can also improve whole vehicle stability and man-machine traveling comfort, improve the platform vehicle simultaneously and improved the plasticity of expanding.
The utility model is achieved by the following technical programs:
A kind of subframe, comprise that longeron is extended on a left side that is fastenedly connected with the vehicle frame main longitudinal grider, longeron is extended on the right side, longeron is extended on a described left side, the right longeron that extends is complementary with the cross-sectional plane of vehicle frame main longitudinal grider bonded assembly fastening end and the cross-sectional plane of vehicle frame main longitudinal grider, and the free end upper surface that longeron and right side extension longeron are extended in a described left side is positioned at the plane that same plane and this plane are lower than vehicle frame main longitudinal grider place.
The free end of longeron is extended on a described left side and the upper surface of the transitional surface between the fastening end is plane or cambered surface or smooth transition curved surface, and the free end of right extension longeron is identical with the fillet surface between its other end with the free end that the transition face of fastening end extends longeron with a left side.
It is parallel with the lower surface of vehicle frame main longitudinal grider with the lower surface of right extension longeron that longeron is extended on a described left side.
A described left side is extended longeron and is extended between the longeron fastening by being connected crossbeam with the right side.
A described left side extend longeron and right inboard of extending longeron be provided with brace panel and or mounting bracket.
Longeron is extended on a described left side, right extension longeron is with the vehicle frame main longitudinal grider and be connected between the crossbeam fastening by rivet.
The beneficial effects of the utility model are:
1, subframe and vehicle frame main longitudinal grider combination, manufacturing process is simple, installs easily, and cost is low, has overcome the defective of unit frame manufacturing moulding difficulty.
2, the utility model is designed to ladder face structure with left and right extension longeron, and the cascaded surface diff-H can reach 53mm; The low early and high after variable section that left and right extension longeron and vehicle frame main longitudinal grider leading portion can be designed to is fastened together, be equivalent to frame assembly leading portion variable section and increased diff-H one time, can effectively downgrade cab heights, improve whole vehicle stability and man-machine traveling comfort; Like this, subframe reduces 100mm even more with the made front end of the frame assembly that the vehicle frame main longitudinal grider is combined into easily than the rear end, and tangible drawing crack can not take place, pull and torsional deflection, can not influence the intensity and the size of frame assembly, avoid the phenomenon of the running car sideslip that vehicle frame global formation structure in the past causes especially.
3, because left and right extension longeron and vehicle frame main longitudinal grider adopt the mode that is fastenedly connected, just can realize the requirement of different in width operator's compartment distortion car by changing the left and right extension girder work of change, improve vehicle platform plasticity greatly and expanded requirement.
