Abstract
The invention relates to a light-weighted balancing suspension frame supporting frame which is characterized in that a main supporting frame body is of a box-shaped structure, triangular and wide-end-up. An upper part of the main supporting frame body is a main body connection plane. Carling connection hole positions are arranged on the circumference of the main body connection plane. A connection end of a V-shaped rod is arranged in the middle of the main body connection plane of the upper part of the main supporting frame body and of a shell-shaped structure. Two shape cavities are symmetrically arranged in the middle of the main supporting frame body in a left and right mode. A crosswise supporting table which extends outwards is arranged in the middle of the main supporting frame body. A balancing shaft match hole is arranged below the middle of the main supporting frame body. Chaplet holes are arranged on left and right sides of the middle of the main supporting frame body. A lower reaction rod connection end is the bottom of the main supporting frame body. A main stressed part of the balancing suspension frame supporting frame is designed to be of a box-shaped structure and has a complete pulled face and a completed stressed face. The distance between the pulled face and the stressed face is large and a neutral plane is arranged in the middle and has large inertia moment and flexural rigidity. When the supporting frame is loaded, the two symmetrical shape cavities can eliminate a low stress zone of a part. The utilization rate of materials is greatly improved and a design idea of structurally equal stress is presented.
Description
Technical field
The present invention relates to a kind of lightweight balance suspension support, belong to the technical field of commercial vehicle/comm..vehicle suspension system.
Background technology
Along with the appearance in succession of the policies such as the quick rise of China's motor vehicle fuel expense, highway weight metering chargings at different levels, the commercial vehicle/comm..vehicle field utilizes new construction, new process to realize that car load lightweight upgrading is extremely urgent.
Balance suspension support is as the core part in equalizing suspension system, be widely used in domestic and international medium and heavy commercial vehicle/comm..vehicle, its mentality of designing is also followed the paces of European producer always, but the technological levels such as the casting of domestic manufacturer, machine add, assembling are comparatively backward, for guaranteeing the reliability of product, producer can only increase specification and the wall thickness of part on the basis of European vehicle type structure form, finally cause product to be difficult to guarantee the lightweight requirements of car load.
Summary of the invention
The purpose of this invention is to provide a kind of lightweight balance suspension support, its main body part of the force with balance suspension support is designed to box-like structure, have complete tension face and compression face, and between tension face and compression face, distance is larger, and neutral surface is placed in the middle, and larger moment of inertia and bending stiffness are arranged, the die cavity of two symmetries at its middle part is when the support stand under load, can cancellation the low stress area of part, significantly improve the utilization ratio of material, embodied the design concept of structure equal stress.
technical scheme of the present invention is achieved in that a kind of lightweight balance suspension support, it is characterized in that: rack body is case type structures, its profile is triangular in shape, wide at the top and narrow at the bottom, rack body the first half is that main body connects the plane, the edge that main body connects the plane is arranged with longeron connecting bore position, V bar coupling end is positioned at the midway location that the rack body upper body connects the plane, V bar coupling end is shell construction, the rack body middle part is two symmetrical die cavities, there is a cross-tie platform that extends outward at the rack body middle part, the rack body middle part has the balance shaft mating holes on the lower side, edge, left and right, rack body middle part has the stud hole, the rack body bottom is lower back reaction rod coupling end.
Described longeron connecting bore position, stud hole is through hole.
The form, two of every sides of being arranged symmetrically with adopted in described stud hole.
When good effect of the present invention is this structure stand under load, part application stress everywhere is very even, two die cavities that arrange in box-like structure reasonably cancellation the low stress area of part, significantly improved the utilization ratio of material, make the balance suspension support weight reducing 30% of dominate on market, at the implementation structure weight-saving simultaneously, can make the reliability of service of the balance suspension support of dominate on market promote 60%, integrated design has improved system stiffness, improves service life.
Description of drawings
Fig. 1 is the constructional drawing of invention.
The specific embodiment
the invention will be further described below in conjunction with accompanying drawing and embodiment: as shown in Figure 1, a kind of lightweight balance suspension support, it is characterized in that: rack body 1 is case type structures, its profile is triangular in shape, wide at the top and narrow at the bottom, rack body 1 the first half is that main body connects plane 5, the edge that main body connects plane 5 is arranged and is had longeron connecting bore position 2, V bar coupling end 9 is positioned at the midway location that rack body 1 upper body connects plane 5, V bar coupling end 9 is shell construction, rack body 1 middle part is two symmetrical die cavities 3, there is a cross-tie platform 4 that extends outward at rack body 1 middle part, rack body 1 middle part has balance shaft mating holes 7 on the lower side, rack body 1 edge, left and right, middle part has stud hole 6, rack body 1 bottom is lower back reaction rod coupling end 8.
Described longeron connecting bore position 2, stud hole 6 is through hole.
The form, two of every sides of being arranged symmetrically with adopted in described stud hole 6.
The lightweight balance suspension support has designed two symmetrical die cavities 3 in the main body force area of part, cancellation the low stress part of part, reduced the weight of part, moment of inertia and the bending stiffness of part have been increased, each die cavity 3 is core under when casting needs, and therefore two studs is set with the fixing position of core at 6 places, stud hole.
V bar coupling end 9 is shell construction, has cancelled traditional reinforced rib scheme, kept the rigidity homogeneity of part key position, the risk of stress concentrations of having avoided the sudden change of part transition zone rigidity to bring.
The longeron connecting bore position 2 of vehicle frame relies on the design advantage of whole box-like structures all to be optimized for through hole, has avoided the low blind threaded connection of reliability.The back of lightweight balance suspension support casts out the integrated and lightweight level that cross-tie platform 4 has improved part in equalizing suspension system.
During stand under load, part application stress everywhere is very even, two die cavities 3 that arrange in the box-like structure of rack body 1 reasonably cancellation the low stress area of part, significantly improved the utilization ratio of material, embodied the design concept of structure equal stress; And the scheme advantage of utilizing box-like structure all is designed to through hole with the connection location of balance suspension support and chassis side rail, has cancelled the low blind threaded type of attachment of reliability, and the connection reliability of system is significantly promoted.
In addition, innovatively cross member of frame gusset-cross-tie platform 4 is integrated on balance suspension support, take full advantage of the good flowing power of molten iron in foundry technique, cast out the version that Sheet Metal Forming Technology is difficult to realize, thereby make structure realize that weight-saving simultaneously, utilize integrated design form elevator system rigidity, the service life of part in the raising system.
The present invention obtains practical application at 6X4 lightweight tractor truck, relies on the breakthrough on design concept, reasonably balance large carrying vital part to reliability and weight-saving double requirements, realize light-weight design for car load and require to provide powerful support.
