The spring assembly comprises a primary steel plate spring, a secondary steel plate spring, a hoop and a central fixing bolt, wherein the middle parts of the primary steel plate spring and the secondary steel plate spring are fixed through the central fixing bolt. The spring assembly is characterized in that: the primary steel plate spring is formed by tightly laminating three bar-type steel plates; annular lifting lugs are arranged at the two ends of the upper bar-type steel plate; three fourths annular lifting lugs are arranged at the two ends of the middle bar-type steel plate; the annular lifting lugs are sleeved on the inner sides of the three fourths annular lifting lugs; bent arcs are arranged at the two ends of the lower bar-type steel plate; the secondary steel plate spring is formed by tightly laminating seven bar-type steel plates; and the length of the seven bar-type steel plates is gradually reduced from inside to outside. According to the front right steel plate spring assembly with the two layers of lifting lugs, the lifting lugs are arranged in two layers, bearing bent arcs are arranged on initial bent parts, the primary steel plate spring and the secondary steel plate spring are laminated without clearance, and the thickness of the primary steel plate spring and the secondary steel plate spring is increased, so the lifting lugs and the middle parts are not easy to crack.
Description
Technical field
The utility model relates to a kind of improvement of automobile leaf spring assembly, right steel plate spring assembly before specifically a kind of double-deck hanger.
Background technology
Automobile leaf spring because simple in structure, Practical Performance good, so be widely used in the dependent suspension of automobile, as damper element.At present on automobile employed before right steel plate spring assembly; Comprise main steel plate spring, additional leaf spring, clip, center fixation bolt and hanger; The main steel plate spring is formed by stacking isometric, the wide steel plate of 4-5 sheet, is provided with hanger at the two ends of the steel plate of the superiors; Additional leaf spring is formed by stacking wide, the not isometric steel plate of 2-3 sheet; Leave the gap between additional leaf spring and the main steel plate spring, this gap can be that promptly the plate face of main steel plate spring is touched at the two ends of additional leaf spring in the middle of staying; The certain distance of main steel plate spring plate face is left in the centre; The two ends of additional leaf spring also can be stayed in this gap, and promptly the plate face of main steel plate spring is not touched at the two ends of additional leaf spring, and the plate face of main steel plate spring is touched at the middle part of additional leaf spring; Through hole is established at middle part at main steel plate spring and additional leaf spring, and the through hole at center fixation screw bolt passes main steel plate spring and additional leaf spring middle part is used fixed by nut, fixes with clip at the middle part from middle part to the two ends of main steel plate spring and additional leaf spring.During use, the middle part of preceding right steel plate spring assembly is fixed on the vehicle bridge, the hanger at two ends is fixed on the automobile chassis frame.Automobile mainly contains the work of main steel plate spring under light condition; When load increased, the gap section of additional leaf spring progressively was adjacent to the plate face of main steel plate spring, progressively bears load.Mode through this elasticity changes can make automobile under different delivery states, realizes comprehensive damping.But right steel plate spring assembly also exists not enough before this: the one because hanger only is provided with one deck, promptly only in the main steel plate spring two ends of the superiors' steel plate be provided with hanger, so insufficient strength often produces fracture; The 2nd, because the centre number of plies is less, even also has certain clearance, so the also fracture easily of center fixation bolt position; The 3rd, owing to do not locate alignment device between layer and the layer, in the vibrations process, be easy to generate displacement, influence in-use performance.
Summary of the invention
The purpose of the utility model is to provide a kind of and is not easy to rupture, and can improve right steel plate spring assembly before the double-deck hanger in damping performance and service life.
For reaching above purpose; The technical scheme that the utility model adopted is: right steel plate spring assembly before this bilayer hanger, comprise main steel plate spring, additional leaf spring, clip and center fixation bolt, and be provided with through hole at the middle part of main steel plate spring and additional leaf spring; The through hole at center fixation screw bolt passes additional leaf spring and main steel plate spring middle part; Use fixed by nut, it is characterized in that: described main steel plate spring is close to by 3 bar shaped steel plates and is formed by stacking, and is equipped with annular hanger at the two ends of last bar shaped steel plate; Be equipped with 3/4 annular hanger at the two ends of middle sheet bar shaped steel plate; It is inboard that the annular hanger is enclosed within 3/4 annular hanger, is equipped with curved arc at the two ends of following sheet bar shaped steel plate, and the curved arc holder is at curved back of the beginning of 3/4 annular hanger; Described additional leaf spring is close to by 7 bar shaped steel plates and is formed by stacking, and the length of 7 bar shaped steel plates is successively decreased from inside to outside successively.
The utility model is also implemented through following measure: the end of the middle sheet of described main steel plate spring and following sheet bar shaped steel plate is a sphenocephaly.
The lower wall of each sheet bar shaped steel plate of described main steel plate spring and additional leaf spring is provided with protruding stupefied; The upper wall of each sheet bar shaped steel plate of described main steel plate spring and additional leaf spring is provided with groove; Groove be buckled in protruding stupefied on; Thereby the superimposed of superimposed and main steel plate spring and additional leaf spring superimposed, each bar steel plate of additional leaf spring of each bar steel plate of main steel plate spring all can accurately be located, and under the damping mode of operation, be not easy displacement.
The advantage of the utility model is: compare with right steel plate spring assembly before present automobile is employed, because hanger has adopted double-deck mechanism, and added the support curved arc in beginning turn of bilge position, so hanger is not easy fracture; It is superimposed that the center adopts main steel plate spring and additional leaf spring not to have the gap, and increased thickness, so the center also is not easy fracture; Since on superposed surfaces, increased the protruding stupefied structure that interlocks with groove, thus accurately locate easily, in service in damping, be not easy to produce the displacement between the adjacent strip shaped steel plate.
