Abstract
The improved structure of spring formula suspension, including by the overlapping leaf spring group constituted of multi-disc leaf spring, the leaf spring group is connected by centre bolt and multiple clips with vehicle bridge, the leaf spring group includes the first leaf spring located at bottom, and the first leaf spring is provided with centre bore, it is characterised in that：The downside end face of first leaf spring is provided with boss, and centre bore runs through the boss, and the corresponding connection part of the vehicle bridge is provided with the groove matched with boss.One kind is improved, and the boss is " ten " font boss, and the groove is " ten " font groove.The utility model uses boss groove structure, and centre bolt undertakes cross shear and shared, and effectively prevent centre bolt and be easily broken off abjection bore causes the situation of suspension frame structure disabler, and its is simple in construction, suspension function it is highly reliable.
Description
Technical field
The utility model is related to a kind of automotive suspension structure, especially a kind of improved structure of spring type suspension.
Background technology
Automotive suspension, is to ensure flexible between wheel or vehicle bridge and automobile bearing system to contact and can transmit load
Lotus, the vehicle body position relaxed in impact, decay vibration and regulation running car, the general name of the relevant device of setting.Suspension is most
Main function is the shear force and the torque that act between wheel and vehicle frame of transmission, and when relaxing garage and crossing uneven road surface
Produced impact, the vibration of decay thus caused bearing system, to ensure the ride comfort of running car.Although more than 100 years
Since automotive suspension from structure type to action principle always in constantly evolution, but it is all by elasticity for structure function
Element, vibration absorber and the part of guiding mechanism three composition.In some cases, a certain parts member and two or three of work is played
With such as leaf spring is simultaneous to play flexible member and guiding mechanism.
Leaf springs of car is flexible member most traditional in automobile suspension system, due to its good reliability, simple in construction, manufacture
The advantages of technological process is short, low cost and structure can be greatly simplified, so as to be widely used.Leaf springs of car be usually by
If the alloy spring steel of dry plate Length discrepancy, which combines one group, is similar to equal strength spring beam.In suspension systems except playing buffering
Effect and it is outer, when it is disposed in automobile longitudinal, and one end and vehicle frame as fixed hinge be connected when, you can shoulder transmission and own
It is each to power and torque, damping effect can be played.
As shown in figure 1, existing spring type suspension structure is the overlapping leaf spring composition leaf spring group of multi-disc, leaf spring group（1）It is logical
Cross centre bolt（2）With multiple clips（9）With vehicle bridge（4）Be connected supporting, centre bolt（2）Through each leaf spring, center spiral shell
Bolt（2）Lower end pass leaf spring group（1）, insert vehicle bridge（4）In the bore of correspondence connection part.The shortcoming of this structure is, vehicle
When running into Uneven road or negotiation of bends, centre bolt（2）Concentration undertakes cross shear, is easily broken off bore, causes
Vehicle bridge（4）Easily be shifted over first leaf spring being in contact, thus cause suspension frame structure disabler, occur running out the way,
Sideslip, whipping, often trigger severe traffic accidents.
The content of the invention
Problem to be solved in the utility model is to provide a kind of improved structure of spring type suspension.
The utility model is adopted the following technical scheme that：Including by the overlapping leaf spring group constituted of multi-disc leaf spring, the leaf spring group
It is connected by centre bolt and multiple clips with vehicle bridge, the leaf spring group includes the first leaf spring located at bottom, the first leaf spring
Provided with centre bore, it is characterised in that：The downside end face of first leaf spring is provided with boss, and centre bore runs through the boss, described
The corresponding connection part of vehicle bridge is provided with the groove matched with boss.
Its principle is：The setting of boss and groove structure, the stress of centre bolt by boss groove structure portions thereof,
Effectively improve the force-bearing situation of centre bolt alone bear cross shear, it is to avoid centre bolt is easily broken off bore
Cause the situation of suspension frame structure disabler.
One kind is improved, and the boss is cylindrical boss, and the groove is cylinder shape groove.
Another improvement is that the boss is " ten " font boss, and the groove is " ten " font groove.Using this knot
Structure, can be prevented effectively from the torsion of the first leaf spring with respect to vehicle bridge in the horizontal direction, advantageously in stable suspensions structure.
The utility model has the following advantages that：1st, it is simple in construction, it is easy to practice and extension.2nd, the reliability of suspension function increases
By force.Using boss groove structure, centre bolt undertakes cross shear and shared, and effectively prevent centre bolt and is easily broken off taking off
Going out bore causes the situation of suspension frame structure disabler, improves the stability of manipulation.

Embodiment
As shown in Figures 1 to 4, the first embodiment of the utility model is included by the overlapping leaf spring group 1 constituted of multi-disc leaf spring,
The leaf spring group 1 is connected by centre bolt 2 and multiple clips with vehicle bridge 3, and the leaf spring group 1 includes first located at bottom
Leaf spring 4, the first leaf spring 4 is provided with centre bore 5, and the downside end face of first leaf spring 4 is provided with boss 6（Boss 6 is circular cylindrical projection
Platform）, centre bore 5 is through the boss 6, and the corresponding connection part of the vehicle bridge 3 is provided with the groove 7 matched with boss 6（Groove 7 is
Cylinder shape groove）.Cylinder shape groove with.
Its principle is：Boss 6 is mutually matched with groove 7, and bore 8 is located at the bottom of cylinder shape groove, constitutes shoulder hole knot
Structure.The stress of centre bolt 2 by the portions thereof of boss 6, effectively improve the alone bear cross shear of centre bolt 2 by
Power situation, it is to avoid centre bolt 2, which is easily broken off abjection bore 8, causes the situation of suspension frame structure disabler.
Second of embodiment as shown in Figure 5, Figure 6, the boss 6 is " ten " font boss, and the groove 7 is " ten " word
Connected in star.Using this structure, in vehicle travel process, the relative torsion of vehicle bridge 3 in the horizontal direction of the first leaf spring 4 can be avoided,
Advantageously in stable suspensions structure.
The boss 6 can also be prismatic（Such as quadrangular, six prisms）Deng mapped structure, groove 7 is Corresponding matching knot
Structure.
The utility model is not limited to the concrete structure of above-described embodiment, and the equivalent transformation of other homogeneous structures each falls within this
Within the protection domain of utility model.
