By dual calculating, location carrying, determine that the position of yoke hanging scroll, connecting rod etc. is selected and the layout deriving lever, be search out new many hanging points bearing point and the target of rock-steady structure, achieve the hinged carrying of " without bridge " vehicle frame and suspension, must use and novelly to match without bridge vehicle frame.
The utility model is according to two yoke, yoke fix shaft and derive lever motion tracking condition, utilize lever principle, scientific algorithm selects rational yoke fix shaft or yoke hanging scroll position, the final bearing point direction of derivation power and the selection of position, can make corresponding arrangement according to vehicle frame space and structure.
Usage condition of the present utility model is: matching without bridge vehicle frame with wheel beam type uses, and traditional vehicle frame is difficult to adjust and reform and reaches this effect.
The beneficial effects of the utility model:
1, effectively integrate and utilize existing space, be dispersed into multiple stress point by a stress point, can Impact direction be changed, do not affect other part placement and function simultaneously, the overall rideability of lifting vehicle.
2, suspension one end directly connects wheel, and impact load multiple spot decomposes, change direction, and average ground speed is improved.
3, the increase of elastic element quantity and reasonable Arrangement, can reduce height of car, space utilization is optimized more, promotes stability, the riding comfort of automobile.
4, controllable wheel skip motion stroke and elastic element bearing capacity step-by-step arrangement.
5, the chassis height that different road conditions are set is convenient to.
6, with without driving systems such as bridge vehicle frames match, automobile can be improved and accelerate to realize motorized, lightweight, intelligentized development.
