Description
Technical field
The present invention relates to a kind of elastic element, especially a kind of steel spring.
Background technology
Suspension is one of chief component on modern automobile, it can vehicle frame and axletree is elastomeric couples together, its main task is transfer function all force and moments between vehicle frame and wheel, and relax the impact load of passing to vehicle frame due to Uneven road, the vibration of the bearing system that decay causes due to impact load, guarantees normally travelling of automobile.
Suspension is comprised of elastic element, guiding mechanism and shock attenuation unit conventionally.Elastic element mainly contains: steel spring, coil spring, rubber spring, air bellow and hydro-pneumatic spring etc.In long-term evolution, because steel spring has simple in structurely, the feature such as manufacturing cost is lower, takes up room little, easy to maintenance, becomes a large amount of elastic elements that adopt in countries in the world.
Steel spring is most widely used a kind of elastic element in automotive suspension, the quality of its stressing conditions also will directly affect automotive suspension, and steel spring in the market all exists that load-carrying capacity is poor, fatigue life is short, affects ride comfort, the limited deficiency of steel spring position dimension of automobile.
Summary of the invention
To the object of the invention is to have in order solving that load-carrying capacity is poor, the limited deficiency of steel spring position dimension, a kind of steel spring to be provided.
Object of the present invention is achieved through the following technical solutions:
A steel spring, comprises the center bolt 10 of steel plate spring assembly 9 and junction steel plate spring assembly 9; Described steel plate spring assembly 9 comprises the first spring leaf 12, the second spring leaf 13, the 3rd spring leaf 14, the 4th spring leaf 15, the 5th spring leaf 16, the 6th spring leaf 17, the 7th spring leaf 18 and the 8th spring leaf 19 of stack successively; The two ends of described the first spring leaf 12 are provided with flat grasswort 1,20, the second spring leaf 13 two ends and are provided with flat bag ear 3,21, and flat grasswort 1 and flat 3, ear of bag are provided with gap, and flat grasswort 20 and flat 21, ear of bag are provided with gap; Described the 4th spring leaf 15 and the 6th spring leaf 17 two ends are equipped with U-shaped clip 4; Described center bolt 10 equates apart from two flat grasswort centre distances.
Between described spring leaf and spring leaf, scribble graphited oil.
In the flat grasswort hole of described flat grasswort, be provided with lining 2.
Described flat bag ear 3 is full bag ear, and described flat bag ear 21 is 1/2 bag ear.
Gap between described flat grasswort and Ping Baoer is 1-7mm.
Described U-shaped clamp 4 is connected with corresponding clip nut 6 by clamp bolt 5, the outer sleeve pipe 7 that is provided with of described clamp bolt 5.
Described U-shaped clip 4 bottoms are passed through respectively rivet 8 and the 4th spring leaf 15 and the 6th spring leaf 17 and are mutually riveted.
The material of described steel plate spring assembly 9 is one side double flute material.
The flat grasswort that the present invention adopts can reduce steel plate spring assembly vertical direction size, and this is because with respect to upper grasswort, has reduced a grasswort aperture in size.
One side double flute material can change the symmetrical state of stress, makes section neutral line shift to the face of bearing, and utilizes steel compression stress to be greater than the characteristic of tensile stress, guaranteeing original rigidity, reduces significantly drawing stress on surface, and saving steel, reduces specific stress.
With respect to prior art, beneficial effect of the present invention is:
Steel spring provided by the invention; when automotive suspension is subject to external impacts; the first spring leaf fracture; the second spring leaf provides protection; strengthen the load-carrying capacity of steel spring, improved fatigue life and economic benefit, maximally utilised limited space; improved the ride comfort of automobile, can meet the need of market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the steel spring shown in Fig. 1 at the a-a ' at clip place to section-drawing.
Wherein: 1, the flat grasswort of 20-, 2-lining, 3,21-Ping Baoer, 4-clip, 5-clamp bolt, 6-clip nut, 7-sleeve pipe, 8-rivet, 9-steel plate spring assembly, 10-center bolt, 11-center nut, 12-the first spring leaf, 13-the second spring leaf, 14-the 3rd spring leaf, 15-the 4th spring leaf, 16-the 5th spring leaf, 17-the 6th spring leaf, 18-the 7th spring leaf, 19-the 8th spring leaf.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the present invention.
As shown in Figure 1-2, a kind of steel spring, comprises the center bolt 10 of steel plate spring assembly 9 and junction steel plate spring assembly 9; Described steel plate spring assembly 9 comprises the first spring leaf 12, the second spring leaf 13, the 3rd spring leaf 14, the 4th spring leaf 15, the 5th spring leaf 16, the 6th spring leaf 17, the 7th spring leaf 18 and the 8th spring leaf 19 of stack successively; The two ends of described the first spring leaf 12 are provided with flat grasswort 1,20, the second spring leaf 13 two ends and are provided with flat bag ear 3,21, and flat grasswort 1 and flat 3, ear of bag are provided with gap, and flat grasswort 20 and flat 21, ear of bag are provided with gap; Described the 4th spring leaf 15 and the 6th spring leaf 17 two ends are equipped with U-shaped clip 4; Described center bolt 10 equates apart from two flat grasswort centre distances.
