Description

A reinforced lower ingot beam assembly

technical field

The utility model relates to a reinforced lower ingot beam assembly, which belongs to the technical field of heavy-duty vehicle chassis accessories.

Background technique

With the development of automobile technology, more and more heavy-duty vehicles are used; at present, most heavy-duty trucks in China are equipped with lower beams to ensure the load capacity of the frame. However, the lower ingot beams in the prior art are all in the shape of "concave" and are welded by multiple single pieces, which is easy to form stress concentration; at the same time, the lower ingot beams are connected with the rear support of the front leaf spring suspension The part is also a relatively weak link in the whole component due to the existence of through holes; therefore, when faced with working conditions such as heavy load and poor road conditions, the rear support of the front leaf spring suspension and the lower ingot beam often suffer damage such as cracking. Phenomenon. Once the rear support of the front leaf spring suspension or the lower ingot beam is damaged, it will seriously affect the normal use of the vehicle and bring huge economic losses to users and enterprises.

Therefore, it becomes very meaningful to strengthen and reinforce the rear support of the front leaf spring suspension and the lower ingot beam. A kind of reinforced lower ingot beam assembly achievement of the utility model is proposed under this situation.

Contents of the invention

In order to solve the problem that chassis accessories such as the front leaf spring suspension rear support and the lower ingot beam are easy to crack in the prior art, the utility model provides a new reinforced lower ingot beam assembly technical scheme, which optimizes the use The overall shape of the lower Yuanbao beam replaces the lower Yuanbao beam of the old structure, and at the same time strengthens the connection between the lower Yuanbao beam and the rear support of the front leaf spring suspension. The specific content of the technical plan is as follows:

A kind of reinforced type bottom Yuanbao beam assembly, is characterized in that, comprises:

An integrally formed lower ingot beam with an obtuse angle and a smooth transition at the bend;

The rear support of the front leaf spring suspension is detachably connected to both ends of the lower Yuanbao beam and provided with at least 4 transverse bolt holes matching the assembled frame;

The reinforcing plate connected to the side of the connection between the lower Yuanbao beam and the rear support of the front leaf spring suspension.

Preferably, the rear support of the front leaf spring suspension and the lower Yuanbao beam are connected and fixed by long bolts.

Preferably, the reinforcing plate and the lower Yuanbao beam are connected and fixed by rivets.

Preferably, the obtuse angles at the bends of the lower ingot beams are all 150°.

Preferably, the cross-section of the lower ingot beam is in the shape of a groove with outward flanges on both wings.

After adopting the above technical scheme, the reinforced lower ingot beam assembly has the following beneficial effects:

The utility model integrates the rear support of the front leaf spring suspension and the connecting support of the Yuanbao beam in the prior art, and strengthens the strength of the rear support of the front leaf spring suspension in the new technical scheme; at the same time, the lower support of the new structure The torsion resistance of the Yuanbao beam is stronger, the stress distribution is more uniform when the force is applied, and greater strength is also provided; after synthesis, the utility model can provide a more reliable lower Yuanbao beam assembly for heavy transport vehicles.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Fig. 1, a kind of reinforced type bottom Yuan Bao beam assembly is characterized in that, comprises:

An integrally formed lower ingot beam 2 with a bending position of 150° and a smooth transition, the cross section of the lower ingot beam 2 is a groove shape with double wings with outward flanging;

The front leaf spring suspension rear support 1 is respectively connected to the two ends of the lower Yuanbao beam 2 with long bolts and provided with 2 sets of 6 transverse bolt holes matching the assembled frame;

The four reinforcing plates 3 on the sides of the joint between the lower Yuanbao beam 2 and the rear support 1 of the front leaf spring suspension are respectively connected by rivets.

The length and curved shape of the underlaying ingot beam 2 are matched with the assembled vehicle.

Comparing Figure 1 and Figure 3, it can be seen that in this embodiment, the rear support of the front leaf spring suspension in the prior art is integrated with the Yuanbao beam connection support, and when in use, only the front leaf spring needs to be suspended by bolts. The rear support 1 of the frame can be fixed on the vehicle frame 4, which reduces a connecting part and strengthens the strength of the rear support 1 of the new front leaf spring suspension; at the same time, the lower ingot beam 2 of the new structure, the integral molding structure makes The lower Yuanbao beam 2 has stronger torsion resistance, and the stress distribution is more uniform when it is subjected to 150° smooth bending, which improves the stress concentration phenomenon in the prior art; the cross section of the lower Yuanbao beam 2 is double wings with outward turning The groove shape of the edge, this structure also provides greater strength; and the reinforcement plate 3 riveted on the lower Yuanbao beam 2 can strengthen the weak link of the lower Yuanbao beam 2 without making more changes , to increase the overall strength level. Through the above improvements, the strength weak link in the prior art is eliminated, the strength of the lower ingot beam assembly is improved as a whole, the probability of cracking is reduced, and it is more conducive to the reliability in application.

The above description of the disclosed embodiments enables those skilled in the art to realize or use the utility model. Various modifications to the embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. The part that is described in detail and partially enlarged and presented is the prior art, and will not be repeated here. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and characteristics disclosed herein.
