Abstract

The utility model discloses a fixing supporting frame for a light truck rear plate spring. The fixing supporting frame for the light truck rear plate spring comprises an upper supporting frame, a lower supporting frame, a suspension frame and an upper reinforcing plate, wherein the upper supporting plate is a channel-type plate, the lower supporting plate is an L-shaped plate, the suspension frame is a U-shaped late, the upper supporting frame stretches across and is welded to the bottom wall and a lateral wall of the suspension frame, the lower supporting frame is simultaneously welded to the bottom of the upper supporting frame and the lateral wall, below the upper supporting frame, of the suspension frame, and the upper reinforcing plate is welded to the top of the upper supporting frame. The fixing supporting frame for the light truck rear plate spring meets the light-weight requirement and the requirement for structural strength.

Description

A kind of light card back leaf spring fixed support

Technical field

The utility model relates to the draft hitch field of light truck.

Background technology

Back leaf spring fixed support is comprising multiple shape and structure as a chief component of rear suspension, is determining the load of connection reliability and the car load of suspension, is one of very crucial parts of car load.Especially in the commercial vehicle/comm..vehicle field, everybody pays special attention to lightweight, load and reliability to car load, and is therefore just very high to the requirement of this support.Because light card back leaf spring fixed support need bear vertical direction, vertically reach transverse force, therefore how satisfying the back support bracket fastened lightweight of leaf spring and structural strength simultaneously is the problem that designer's needs are considered.

The utility model content

The purpose of this utility model provides a kind of weight-saving and gently blocks back leaf spring fixed support, and this support can satisfy the structural strength requirement simultaneously.

For achieving the above object, the utility model provides following technical scheme:

A kind of light card back leaf spring fixed support comprises:

Upper bracket;

Lower bracket;

Suspension bracket;

Upper reinforcing plate;

Described upper bracket is groove type plate, described lower bracket is the L template, described suspension bracket is U-shaped plate, described upper bracket rides on the diapire that is welded on described suspension bracket and the sidewall, the sidewall welding that described lower bracket rides with the quilt of the bottom of described upper bracket and described suspension bracket simultaneously, described upper reinforcing plate is welded on the top of described upper bracket.

Selectively, described upper bracket, described lower bracket, described suspension bracket and described upper reinforcing plate are one-body molded of punching press.

Selectively, has the reinforced rib that stamps out on described upper bracket, the described lower bracket.

The beneficial effects of the utility model are:

Back each parts of leaf spring fixed support in the utility model are some or all of to form shape separately by punching press, and welding links together then, satisfies lightweight and structural strength requirement simultaneously.

Further, when punch forming, stamp out reinforced rib at upper and lower support, improved structural strength.

The specific embodiment

In conjunction with Fig. 1, Fig. 2 and Fig. 3, it has specifically illustrated the annexation between support bracket fastened each parts of light card back leaf spring.As seen, suspension bracket 2 is U-shaped plate from Fig. 3 and Figure 10, and it has diapire 21, relative the first side wall 22 and second sidewall 23.Upper bracket 1 and suspension bracket 2 are for being welded to connect, and upper bracket 1 straddles on the diapire 21 and second sidewall 23 of suspension bracket 2.Lower bracket 3 is welded to connect with the bottom of upper bracket 1 and second sidewall 23 of suspension bracket 2 simultaneously, so has formed firm stressed support between upper bracket 1, suspension bracket 2 and the lower bracket 3, and overall construction intensity is good.Upper reinforcing plate 4 is welded on the top of upper bracket 1, and purpose is the Joint strenght that strengthens light card back leaf spring fixed support and back leaf spring.

In conjunction with Fig. 4 to Fig. 8, it has shown the concrete shape of upper bracket 1.Upper bracket 1 is the grooved plate, and is preferably by the impact style moulding, lighter with Casting Parts phase weight/power ratio.And upper bracket 1 has formed reinforced

rib

11,12 in punching course, improves the stress-bearing capability of upper bracket 1.

In conjunction with Fig. 9, Figure 10, suspension bracket 2 is U-shaped plate as seen from the figure, the same preferred punch forming of adopting.

In conjunction with Figure 11 to Figure 14, and in conjunction with Fig. 3, lower bracket 3 is L template spare, same preferred employing punch forming, and lower bracket 3 has formed reinforced rib 31,32, the stress-bearing capability of raising lower bracket 3 in punching course.

In conjunction with Figure 15, Figure 16, and in conjunction with Fig. 5, the cross sectional shape of the shape of upper reinforcing plate 4 and upper bracket 1 is complementary, the same preferred punch forming of adopting.

Because upper bracket 1, suspension bracket 2, lower bracket 3 and upper reinforcing plate 4 are one-body molded of punching press, so their total weight is lighter than the Casting Parts under the equal stress condition, has realized lightweight.And, in above-mentioned each parts, processed a plurality of holes, be used for gently blocking back leaf spring fixed support and be riveted to vehicle frame, and be connected with leaf spring by devices such as pins.

Though the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and only be subjected to the restriction of claim, those of ordinary skills can easily make amendment to it and change, but do not leave essence design of the present utility model and scope.
