Description

The Few Leaf Spring of a kind of termination band tenon structure

Technical field

The utility model relates to automobile leaf spring technical field, is specifically related to the Few Leaf Spring of a kind of termination band tenon structure.

Background technique

Energy-conservation, reduction of discharging has become the eternal theme of current automobile industry development.Leaf spring is a vitals on automobile suspension system, and the few sheet spring of same load-carrying replaces multiple-leaf spring can alleviate about 50% of leaf spring deadweight, saves the energy, decreases the fuel consume of automobile.

Traditional Few Leaf Spring adopts the method adding plastic spacer in end allow between sheet has gap to rub to reduce between sheet, and end utilizes rivet to be banded together by each reed in conjunction with clamp to prevent reed from use misplacing.Because the load of heavy hauler carrying is very large, termination plastic spacer very easily weares and teares, and in use must change termination pad, keeps in repair very inconvenient.In transportation process and when installing and using, the clip at backup plate spring two ends to prevent leaf spring from misplacing, and clip thinner thickness, the leaf spring that insufficient strength produces dislocation in use can reduce working life, even can interfere with vehicle frame.

Model utility content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides that a kind of structure is simple, the Few Leaf Spring of low cost of manufacture, the termination band tenon structure that easy to maintenance, performance safety is stable.

The Few Leaf Spring of a kind of termination band tenon structure, comprise the reed of several stacked settings, end, described reed two ends is by the mutual clamping of tenon structure, described tenon structure is groove and protruding cooperating structure, the end face of described lowermost end leaf end offers groove, the bottom surface of all the other leaf ends offers projection, and end face offers groove.

As further describing technique scheme:

Described groove, protruding length direction are consistent with the longitudinal direction of reed, are arranged on the vertical center line of reed, and protruding length is less than groove, and protruding is Spielpassung with groove.

As further describing technique scheme:

Described reed be interval with intermediate washer, be interconnected and fixed by centre bolt attaching nut in the middle part of reed and intermediate washer.

As further describing technique scheme:

Described lowermost end reed linearly type, the reed two ends downward bending above it becomes " Z " font, and only termination contact between adjacent reed, middle part intermediate washer separates, and remaining part leaves gap.

The utility model structure is simple, assemble very convenient, arranged by the clamping of leaf end tenon structure, the setting of the termination pad between traditional Few Leaf Spring sheet and sheet, clamp can be cancelled, save the cost of assembling clamp and termination pad and deducted the trouble changing termination pad in using process, in the process of automobile running, effectively can prevent the dislocation between reed.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Fig. 2, Fig. 3 are the structural representation of leaf end in the utility model;

Fig. 4 is leaf end sectional view in the utility model;

Fig. 5 is that in the utility model, leaf end bends close-up schematic view.

Marginal data:

1, reed; 11, groove; 12, protruding; 2, intermediate washer; 3, centre bolt; 4, nut.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

See Fig. 1, the Few Leaf Spring of a kind of termination band tenon structure that the utility model provides, comprise the reed 1 of several stacked settings, reed 1 be interval with intermediate washer 2, centre bolt 3 is through the middle part of each reed 1 with intermediate washer 2, attaching nut 4 realizes being interconnected and fixed of each reed 1 and intermediate washer 2, and end, reed 1 two ends is by the mutual clamping of tenon structure.

Because end, reed 1 two ends is by tenon structure clamping, can directly contact between end, without the need to adopting termination pad to reduce the friction between reed, reduce cost and deducted the trouble changing termination pad in using process, the clamping of tenon structure simultaneously replaces clip, eliminates the cost making clamp.

In the present embodiment, see Fig. 2 and Fig. 3, tenon structure is groove and protruding cooperating structure.The end face of lowermost end reed 1 end offers groove 11, and the bottom surface of all the other reed 1 ends offers protruding 12, and end face offers groove 11.Object is, reed 1 end can be located rapidly, assemble very convenient, in the process of automobile running, effectively can prevent the dislocation between reed 1.

In the present embodiment, see Fig. 2, Fig. 3 and Fig. 4, the length direction of groove 11, projection 12 is consistent with the longitudinal direction of reed 1, is arranged on the vertical center line of reed 1, and the length of protruding 12 is less than groove 11, and projection 12 and groove 11 are Spielpassung.Object is, improves speed and the ease of assembling.

In the present embodiment, see Fig. 5, lowermost end reed 1 linearly type, the reed 1 two ends downward bending above it becomes " Z " font, and only termination contact between adjacent reed 1, middle part intermediate washer 2 separates, and remaining part leaves gap.Object is, in use, arranging of gap can reduce noise, decreases the frictional force existed between sheet, enables Few Leaf Spring absorb impact force better, does high ride of vehicle and riding comfort.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
