Abstract
The utility model belongs to the technology of automobile suspensions and relates to a rubber spring of an automobile suspension. The rubber spring of the automobile suspension comprises a plurality of mutually laminated metal isolation plates and rubber layers, wherein the metal isolation plates at the outermost two layers are respectively an upper isolation plate and a lower isolation plate, and axial holes arranged in the metal isolation plates and the rubber layers. Compared with the existing rubber spring, the rubber spring has greatly improved anti-fatigue performance and efficiently prolonged service life, improves the driving smoothness of an automobile, reduces the dynamic load of the automobile body, prolongs the service life of the automobile, and improves the comfort of a driver.
Description
Technical field
The utility model belongs to the automotive suspension technology, relates to a kind of automotive suspension rubber spring.
Background technique
The suspension rubber spring is main load-bearing part and the key component of heavy-duty car new type rubber suspension, and it is by metal and rubber is stacked is bonded, and metal plays skeleton and supporting effect, and rubber plays vibration damping and connection function.
The rubber spring function is to connect vehicle bridge and vehicle frame, support tare, absorption and elimination and vibrate, increase to greatest extent the frictional force between tire and the road surface, guarantee the steering stability of manipulation, improve ride of vehicle, reduce the dynamic load of body portion, prolong the working life of automobile, and the comfort level of guaranteeing the occupant.
In recent years, domestic some rubber product manufacturing enterprise progressively pays close attention to the rubber suspension industry, and contact with domestic heavy card manufacturer, imitated U.S. Han Ruisen rubber suspension exploitation highway car rubber suspension product, entrucking test run of portioned product, but suspension rubber spring assembly technology that is that all right is ripe, unreasonable structure, fatigue ruption easily occurs, and the life-span is shorter.
The model utility content
The purpose of this utility model is: provide a kind of rational in infrastructure, install simple, anti-fatigue performance is good, the automotive suspension rubber spring of long service life.
The technical solution of the utility model is: a kind of automotive suspension rubber spring, the metal partion (metp) and the rubber layer that comprise some mutual stacked settings, wherein, outermost double layer of metal dividing plate is respectively upper clapboard and lower clapboard, wherein, be provided with axial bore in described metal partion (metp) and the rubber layer, described axial bore is for vertically running through through hole or the blind hole of metal partion (metp) and rubber layer.
The rubber layer that metal partion (metp) is adjacent connects marginal existence transition chamfering.
Described transition chamfering is fillet, right angle or seamlessly transits the angle.
The transition zone of described transition chamfering is between 0.5mm to 20mm.
In described some rubber layers, the thickness of intermediate rubber layer is maximum, and the rubber layer thickness of both sides successively reduces before and after this intermediate rubber layer.
The layer of adjacent rubber layer is poor be controlled at the intermediate rubber layer thickness 30% in.
Consistent with the n layer rubber thickness that begins from lower clapboard from the n layer rubber layer thickness that upper clapboard begins.
Technique effect of the present utility model is: the utility model automotive suspension rubber spring is by the axial bore setting, and rubber layer thickness control and chamfering setting, thereby can significantly improve the anti-fatigue performance of rubber spring, effectively prolongs its working life.Prove by experiment, after the automotive suspension rubber spring of the present utility model entrucking, its life-span improves more than 200% with respect to existing rubber spring, has very significant technique effect.

Embodiment
Below in conjunction with drawings and Examples the utility model is described further:
Please consult simultaneously Fig. 1, Fig. 2 and Fig. 3, the utility model automotive suspension rubber spring comprises metal partion (metp) 1 and the rubber layer 2 of some mutual stacked settings, and wherein, outermost double layer of metal dividing plate is respectively upper clapboard 4 and lower clapboard 5.Described metal partion (metp) 1 and rubber layer 2 arrange axial bore 3, and this axial bore is for vertically running through through hole or the blind hole of metal partion (metp) and rubber layer, to improve the anti-fatigue performance of spring.
The rubber layer number of plies is odd number, the thickness of intermediate rubber layer is maximum, the rubber layer thickness of both sides successively reduces before and after this intermediate rubber layer, layer is poor be controlled at the intermediate rubber layer thickness 30% in, and each rubber layer thickness is symmetrically distributed centered by intermediate rubber layer, so that each rubber layer stress equilibrium improves anti-fatigue performance, increase the service life.Consistent with the n layer rubber thickness that begins from lower clapboard such as the n layer rubber layer thickness that begins from upper clapboard.
If the rubber layer number of plies is even number, the n layer rubber layer thickness that then similarly begins from upper clapboard is consistent with the n layer rubber thickness that begins from lower clapboard, and from upper lower clapboard, rubber layer thickness successively reduces, and middle two-layer rubber layer thickness is equal and the thickest.
In addition, the rubber layer that metal partion (metp) in the utility model automotive suspension rubber spring is adjacent connects marginal existence transition chamfering, this transition chamfering can seamlessly transit the angle for fillet, right angle or other, transition zone is (length dimension of transition zone) between 0.5mm to 20mm, to reduce the stress of rubber-metal binding site, improve working life.
Embodiment 1: the rubber number of plies is 5 layers in the automotive suspension rubber spring, and intermediate layer thickness is 30mm, and the thickness difference of adjacent rubber layer is 5mm, through-hole diameter 20mm, and the transition chamfering is circular arc chamfering, chamfer radius is 8mm.
Embodiment 2: the rubber number of plies is 6 layers in the automotive suspension rubber spring, and intermediate layer thickness is 28mm, and the thickness difference of adjacent rubber layer is 4mm, through-hole diameter 22mm, and the transition chamfering is for seamlessly transitting the angle, and transition zone is of a size of 9mm.
