Abstract
The utility model discloses a shock-proof cantilever beam structure. The shock-proof cantilever beam structure comprises a closed-loop support assembly which comprises an upper support assembly and a lower support assembly, wherein two ends of each of the upper support assembly and the lower support assembly are respectively provided with a protruded supporting frame, the corresponding supporting frames of the upper support assembly and the lower support assembly are connected with each other through long bolts, the lower part of each supporting frame of the lower support assembly is provided with a shock-absorption cushion, the upper part of each supporting frame of the upper support assembly is provided with a cantilever support, and each shock-absorption cushion is provided with energy-absorption holes along the axial direction. Different structures can be designed according to a to-be-fixed automobile component, and a stress point of a box body can be well transferred through the support structure; the uniformity in stress of the box body is achieved by virtue of an energy-absorption shock-absorption device.
Description
Technical field
The utility model relates to a kind of connected support structure, particularly on a kind of heavy motor vehicle, adopts the device of cantilever securing part and vehicle frame.
Background technology
Most heavy motor vehicle adopts the fixing heavier auto parts and components of cantilever, parts are suspended on the both sides of automobile chassis frame, use bolt and drawstring to act directly on casing, make like this weight of casing all be applied to the junction of support and casing, and support and vehicle frame are by being rigidly connected, traditional antinose-dive leg bearing, at box inside welded framework stay bearing plate, for support, connect, but in long use procedure, due to high temperature, the vibration of high frequency time, easily lost efficacy in junction at support and casing, major cause is that stress is concentrated, the surface embrittlement of welding rear box, without vibration reducing measure.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the easy defect losing efficacy of support and casing junction, and a kind of antivibration cantilever design is provided.
For solving above technical matters, the technical solution adopted in the utility model is:
A kind of antivibration cantilever design, comprise closed loop bracket assembly, this closed loop bracket assembly comprises upper bracket assembly and lower bracket assembly, the two ends of upper bracket assembly and lower bracket assembly are respectively equipped with the bracing frame of protrusion, upper bracket assembly is connected by overbolt with bracing frame corresponding to lower bracket assembly, the bracing frame bottom of lower bracket assembly is lined with shock pad, and cant cantilever is equipped with on the bracing frame top of upper bracket assembly.
The feature of above structure be support with casing between do not have rigidity to contact, avoided the direct transmission of vibration and stressed skewness.On the bracing frame passing at overbolt, all do the structure of strengthening processing and having increased vibration damping, prevented that like this rupture because of insufficient strength in bolt position when there is vibration, avoided something unexpected happened, also better played the effect of vibration reduction and cushioning.
As a kind of preferred technical scheme, on described shock pad, have vertically energy-absorbing hole.Shock pad adopts nylon material, energy-absorbing hole is set and can guarantees certain rigidity, can play again the effect of vibration reduction and cushioning.
Antivibration cantilever design described in the utility model adopts closed loop support, the different structure of fixed car parts design as required, the design of supporting structure is well shifted the stress point of casing, and has increased energy-obsorbing and damping device, makes the stressed even of casing.It is simple in structure, reasonable in design, and intensity is good, and vibration-isolating effect is good, durable in use, practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is shock pad.
In figure, 1-upper bracket assembly, 2-lower bracket assembly, 3-overbolt, 4-shock pad, 5-cant cantilever, 6-energy-absorbing hole, 7-casing, 8-jam nut.
The specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, the utility model is done to further clear, complete explanation.
As shown in Figure 1, a kind of antivibration cantilever design described in the utility model, comprise closed loop bracket assembly, this closed loop bracket assembly comprises upper bracket assembly 1 and lower bracket assembly 2, the two ends of upper bracket assembly 1 and lower bracket assembly 2 are respectively equipped with the bracing frame of protrusion, upper bracket assembly 1 is connected by overbolt 3 with the bracing frame of lower bracket assembly 2 correspondences, and the bracing frame bottom of lower bracket assembly 2 is lined with shock pad 4, and cant cantilever 5 is equipped with on the bracing frame top of upper bracket assembly 1.
Wherein, lower bracket assembly 2 mainly play supporting box 7 and with the interconnective effect of upper bracket assembly 1.Upper bracket assembly 1 mainly plays the effect being connected with cant cantilever 5, lower bracket assembly 2, replaced the structure that traditional support is connected with casing, it forms closed loop configuration together with lower bracket assembly 2, play the effect of static housing 7, increase area of contact, make casing 7 stressed even in vibration processes.Overbolt 3 coordinates with jam nut 8, mainly plays connection fastening effect.Shock pad 4 adopts nylon material to make, and mainly plays the effect of alleviating vibratory impulse.
As shown in Figure 2, on described shock pad, have vertically energy-absorbing hole 6.Energy-absorbing hole 6 can guarantee certain rigidity, can play again the effect of vibration reduction and cushioning.
The claimed scope of the utility model is not limited to the above specific embodiment; to those skilled in the art; the utility model can have various deformation and change, all any modifications of doing within design of the present utility model and principle, improves and is equal within replacement all should be included in protection domain of the present utility model.
