Upper skeleton 3: upper skeleton 3 is foundry goods, its inside is solid construction, its mechanical characteristics is better than the sheet metal component of prior art, has stronger impact resistance, can be because of metal fatigue deformation; Meanwhile, the reasonable in design of upper skeleton 3, the effect of reinforcing lower flange 31 and 22 impacts of opposing position-limited rack, as stressed key position, is being born in its top, therefore its structure has been done suitable reinforcing, then removes non-stress position, and structure is optimized to loss of weight.
Mounting bracket 6: mounting bracket 6 is foundry goods, sheet metal component with respect to prior art, the mechanical characteristics of foundry goods is better, particularly the ability of anti-metal fatigue will be far superior to sheet metal component, mounting bracket 6 is as load-supporting part, if use the thin sheet metal component of structure, the stressed meeting that stretches for a long time causes metal fatigue, the stressing conditions that can change driving engine and vehicle frame, has a strong impact on the operation of automobile.The design adopts foundry goods, and support riser 61 middle parts are fixedly connected with the top of support transverse slat 62 by reinforced rib 63, has improved the mechanical strength of mounting bracket 2.Meanwhile, in the bottom of support transverse slat 62, be provided with a plurality of lightening holes, for expendable weight, and at support transverse slat 62 junction with upper skeleton 3, do consolidation process, increased the axial length of mounting bracket fixed orifice 66, strengthened being connected of mounting bracket 6 and upper skeleton 3.
The installation of automobile dynamic system: because automobile dynamic system assembles rear integral installation on suspending apparatus, in prior art, the first bolt is fixed on plate body, when dynamic assembly falls, its attitude is adjusted difficulty, support and cushion assembly hole bit alignment difficulty, and easily scratching damages the screw thread of the first bolt, affects fastening performance; The design has adjusted the mounting means of bolt, at upper skeleton 3 tops, be provided with two tapped bore 32, between two tapped bore 32, be provided with locating dowel pin 33, after locating dowel pin 33 is aimed at indent taper hole 65, fine setting installation site makes mounting bracket fixed orifice 66 align with tapped bore 32, then install fixedly mounting bracket 6 of frame bolt 64, thereby reach the object of fixed car power system.Because the suspending apparatus of power system is at least four, according to the fixing means of prior art, be difficult to adjust alignment, repeatedly adjust the wearing and tearing that cause again bolt thread after installing, according to the design's mounting means, the adjustment of installation site is relatively simple, and can not grind colored bolt thread, make the fixing more firm, reliable of power system.
The design adopts two upper skeleton bolts 64 to connect mounting bracket 6 and upper skeleton 3, adopt two lower skeleton bolts 53 to fix lower skeleton 5, with respect to the one-bolt fastening of prior art, the design's connection is stablized more, being difficult for deflecting gets loose, and reliability is higher.
90 degree connect: belong to conventional connection mode, refer to that the angle between two connection objects is 90 degree, implement in the design and refer to that the angle between interconnective anticollison block 42 and collision mat 43 is 90 degree.
