Abstract

The utility model provides a plate spring seat and a drive axle. The plate spring seat comprises a base and a limiting portion and further comprises a base sliding plate and a side lining plate, wherein the base sliding plate is located on one side of the base close to a plate spring and detachably connected with the base, the side lining plate is located on one side of the limiting portion close to the plate spring and fixedly connected with the limiting portion. The base sliding plate of the plat spring base is detachably connected with the base, the side lining plate is fixedly connected onto the limiting portion, the disadvantage of the whole plate spring seat replacement after the plate spring seat is abraded is avoided, only the base sliding plate or the side lining plate is required to be replaced, the plate spring seat is easy to maintain, and the maintenance cost is low.

Description

A kind of spring block and drive axle

Technical field

The utility model relates to automobile dynamic system, particularly a kind of spring block and drive axle.

Background technology

Spring block be arranged on automobile in, on rear driving axle, to leaf spring play support and guiding effect, along with the vehicle continuous variation of leaf spring camber under steam.For preventing leaf spring wearing and tearing and controlling cost, hardness and the resistance to abrasion of leaf spring are higher than spring block, and therefore wearing and tearing easily appear in spring block, when after spring block undue wear, in can causing, rear driving axle load-carrying distributes and increase the weight of, in impact, service life of rear driving axle.

Existing spring block comprises the base contacting with leaf spring and the limiting section that leaf spring is played to position-limiting action, and base and limiting section combine by one-body molded, and when needing to change whole spring block after base wearing and tearing, maintenance difficulties is large, and cost is high.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of and safeguards easily, the spring block that maintenance cost is low and drive axle.

For solving the problems of the technologies described above, the spring block that the utility model provides comprises base and limiting section, also comprise end slide plate and side backing plate, slide plate of the described end is positioned at described base and removably connects near a side of leaf spring and with described base, and described side backing plate is positioned at described limiting section and is fixedly connected with near a side of leaf spring and with described limiting section.

Preferably, slide plate of the described end is connected with described bolt of lower base.

Preferably, slide plate of the described end is arch configuration, and its two ends and described base removably connect.

Preferably, between described base and slide plate of the described end, be also provided with bradyseism plate, between described bradyseism plate and slide plate of the described end, there is cavity.

Preferably, the thickness of slide plate of the described end is greater than the thickness of described side backing plate.

The utility model also provides a kind of drive axle, and it comprises above-mentioned spring block.

End slide plate and the base of the spring block that the utility model provides removably connect, and on limiting section, be fixedly connected with side backing plate, and avoid the rear drawback of changing whole spring block of spring block wearing and tearing, only need to change end slide plate or side backing plate, spring block is not only safeguarded easily, and maintenance cost is low.

Fig. 3 is the structural representation of the utility model drive axle embodiment.

In figure, indicate as follows:

Base-1, limiting section-2, slide plate-3, the end, bolt-30, side backing plate-4, bradyseism plate-5, cavity-6, axle housing-7.

Detailed description of the invention

For the above-mentioned purpose, the feature and advantage that make utility model can become apparent more, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.

A lot of details are set forth in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that, and therefore the utility model is not subject to the restriction of following public specific embodiment.

As depicted in figs. 1 and 2, the spring block that the utility model provides, comprise base 1 and limiting section 2, limiting section 2 can adopt the conventional structure in this area, as hook-type or inverted U groove etc., also comprise end slide plate 3 and side backing plate 4, slide plate of the described end 3 is positioned at described base 1 and removably connects near a side of leaf spring and with described base 1, described side backing plate 4 is positioned at described limiting section 2 and is fixedly connected with near a side of leaf spring and with described limiting section 2, wherein removably connecting between end slide plate 3 and base 1 can be realized by the mode such as buckle or bolt, being fixedly connected with between side backing plate 4 and limiting section 2 can realize by the mode such as welding or be threaded.

When the spring block that the utility model provides uses, base 1 does not directly contact with leaf spring, but contact with slide plate of the detachable end 3, simultaneously in order to prevent that limiting section 2 from producing wearing and tearing, on limiting section 2, arrange and be fixedly connected with the side backing plate 4 corresponding with the side of leaf spring, in the time that spring block produces wearing and tearing, change the object that end slide plate 3 or side backing plate 4 can reach maintenance panel spring abutment, safeguard that easily maintenance cost is low.

In order to facilitate the installation of end slide plate 3, and ensure the assembly reliability of end slide plate 3, slide plate of the described end 3 is connected with described base 1 bolt, and number and the installation site of bolt 30 are selected according to the actual requirements.

In a preferred embodiment of the present utility model, slide plate of the described end 3 is arch configuration, and its two ends and described base 1 removably connect, and the end slide plate 3 of arch configuration can play the effect of damping, reduces the degree of wear of end slide plate 3.

In another preferred embodiment of the present utility model, between described base 1 and slide plate of the described end 3, be also provided with bradyseism plate 5, between described bradyseism plate 5 and slide plate of the described end 3, there is cavity 6, bradyseism plate 5 and cavity 6 the effect that can play damping is set, reduce the degree of wear of end slide plate 3.

For the cost of control desk spring abutment reasonably, the thickness of slide plate of the described end 3 is greater than the thickness of described side backing plate 4, can effectively increase like this service life of the end slide plate 3 that relative wear degree is larger.

As shown in Figure 3, the utility model also provides a kind of drive axle, and it comprises above-mentioned spring block, and spring block is arranged on axle housing 7.The drive axle that the utility model provides safeguards that easily maintenance cost is low, after spring block wearing and tearing, need not change whole spring block, only needs to change end slide plate 3 or side backing plate 4.

Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and be only subject to the restriction of claims, those of ordinary skill in the art can easily modify to it and change, but do not leave essence design of the present utility model and scope.
