Principle of the present utility model is described as follows:
The dynamic assembly suspension of 4 layouts, thereafter suspension arrangement on clutch bell, because of commercial vehicle/comm..vehicle dynamic assembly heavier, rear end of the cylinder block face additional bending moment can be larger, and the outstanding upper vibration of dynamic assembly simultaneously can be larger, under identical vibration isolation rate condition, the vibration meeting that passes to vehicle frame is larger, affects travelling comfort.
The dynamic assembly suspension of 6 layouts, arrange on dynamic assembly suspension basis at 4, increase auxiliary suspension device at change speed gear box afterbody, play the effect of controlling change speed gear box displacement and reducing rear end of the cylinder block face additional bending moment, this mode is generally applied more in heavy goods vehicles, high for its manufacturing cost of compact car, can not significantly improve vibration isolating effect simultaneously.
The design adopts 4 arrangements, change speed gear box middle part will be moved on to behind the installation site of rear-suspending 2, increase front-suspension 1 span longitudinal with the car load of rear-suspending 2, make rear-suspending 2 take into account 2 rear-suspendings of 6 arrangements and the effect of 2 auxiliary suspension, play the effect of supporting dynamic assembly, the displacement of control change speed gear box, reducing the additional bending moment of rear end of the cylinder block face, the vibration acceleration mean effective value that when idling, dynamic assembly respectively suspends obviously reduces, when idling, car load traveling comfort significantly improves, and reduces production costs by cancelling auxiliary suspension simultaneously.
The design can directly apply to existing four point suspension vehicle, and do not change assembling structure on it, because the design is the rear-suspending being fixed on change speed gear box, crossbeam is not set, do not take the upper dress space of change speed gear box, therefore the design can adapt to various structure, Applicable scope is wider, can suitability strong.
The design's rear-suspending 2 plays main carrying effect, and in documents, suspend as auxiliary suspension, under conventional operating mode, substantially do not stress, the stress at gear-box top cover place is less, and the installation place of rear-suspending 2 is stressed larger on the design's change speed gear box, therefore the design has strengthened the mechanical strength of mounting bracket 5 and gear box casing side plate 4, on change speed gear box side plate 4, be provided with two cross reinforcings 41 and many walings 42, cross reinforcing 41 is connected with waling 42 is vertical, cross reinforcing 41 offers support with the junction of waling 42 tapped bore 43 is installed, support is installed tapped bore 43 and is fixedly connected with by support hold-down bolt 44 with support installation through hole 55, above-mentioned design has improved the intensity of gear box casing and mounting bracket 5 junctions, make change speed gear box and mounting bracket 5 form an entirety, reduce gear box casing causes cracking risk because rear-suspending 2 is installed.
Suspending cushion 8: the outer circumference surface 85 of inner frame 81 is fixedly connected with the inner peripheral surface of polysulphide rubbers 82, and outer circumference surface 85 is gradually narrow cambered surface; Recessed support ring 83 comprises support ring fixed part 86 and recessed ring portion 87, the anchor ring of support ring fixed part 86 is fixedly connected with suspension bracket 7, sidepiece in support ring fixed part 86 rings is fixedly connected with the top of the recessed ring portion 87 that is arranged at its below, described recessed ring portion 87 is arranged in polysulphide rubbers 82, recessed ring portion 87 is gradually narrow recessed annular, and in recessed ring portion 87, the circle diameter at nearly support ring fixed part 86 places is greater than the circle diameter at remote branch of a clan pushing out ring fixed part 86 places; With respect to the mushroom-shaped suspending soft cushion assembly in documents, the design's inner frame 81 matches with recessed support ring 83, improve the ability of suspending cushion 8 anti-lateral stress, simultaneously for suspending cushion 8 bearing function straight down, in documents, polysulphide rubbers is subject to pulling force straight down, and the design is due to gradually narrow cambered surface design of outer circumference surface 85, what polysulphide rubbers 82 was subject to is the pressure to side-lower, effectively avoid polysulphide rubbers because excessively stretching and tear, extended the service life of suspending cushion 8.
Vibration acceleration mean effective value is an index weighing vibration, and the vibration acceleration mean effective value more vibration of roadlice is less; And the vibration maximum of dynamic assembly when auto idle speed, therefore the size of vibration acceleration mean effective value when auto idle speed is an important indicator weighing car load traveling comfort.
