Description

A kind of subframe assembly

Technical field

This utility model is related to automobile chassis field, and in particular to a kind of subframe assembly.

Background technology

In the McPherson independent front suspension of automobile, most subframes adopt collar tie beam structure.At present collar tie beam mainly by Crossbeam is formed with two longitudinal beam weldings.But the collar tie beam that this kind of welding manner is made, there is the deficiencies such as weld seam, tear sometimes, Cause the fatigue strength of whole subframe low.

Utility model content

The purpose of this utility model is to provide a kind of fatigue strength high subframe assembly.

To reach above-mentioned purpose, base case of the present utility model is：A kind of subframe assembly, including crossbeam upper plate, horizontal stroke Beam lower plate, stabilizer bar arm, swing arm installing rack and bracket mounting sleeve, also including cold stamping shaped n shape collar tie beams；It is described steady Fixed pole support and swing arm installing rack are welded respectively with n shapes collar tie beam.

In the subframe assembly of this programme, main load bearing component n shapes collar tie beam largely overcomes tradition using cold stamping shaped The defect that existed by crossbeam and longitudinal beam welding of collar tie beam, substantially increase its fatigue strength.

Preferred version one：Based on scheme preferred version, the edge of the crossbeam upper plate and the edge of crossbeam lower plate Matching, the end face of the bracket mounting sleeve is provided with lines.The advantage of this programme：Avoid the occurrence of crossbeam upper plate to match somebody with somebody with crossbeam lower plate During conjunction, there is edge interference.The end face design lines of bracket mounting sleeve, substantially increases its fixed performance and positioning precision.

Preferred version two：Preferably one preferred version：Multiple line cards are welded with the inside of the n shapes collar tie beam Seat, the lines is zigzag.The advantage of this programme：In the inner side sealing wire deck of n shape collar tie beams, facilitate the cloth of circuit and oil pipe Put.It is to facilitate processing and fabricating that lines is designed as zigzag.

Preferred version three：Preferably two preferred version：It is provided between the crossbeam upper plate and crossbeam lower plate Support bar, strengthens the rigidity and intensity of its whole subframe.

Preferred version four：Based on scheme, the preferred version of any one of preferred version one to three：On the n shapes collar tie beam Towing hook is provided with, the crossbeam lower plate is provided with acoustic filter suspension hook.The advantage of this programme：Towing hook facilitates the delivery of vehicle, acoustic filter Suspension hook facilitates acoustic filter to install.

Preferred version five：Preferably four preferred version：The n shapes collar tie beam is provided with for installing attenuator Installation position.The use range of subframe assembly is improved, when engine arrangement is four point positioning, when needing attenuator, directly in peace Dress installs attenuator at position.

Description of the drawings

Fig. 1 is a kind of structural representation of subframe assembly of this utility model；

Fig. 2 is enlarged drawing at A in Fig. 1.

Specific embodiment

This utility model is described in further detail below by specific embodiment：

Reference in Figure of description includes：N shapes collar tie beam 10, bracket mounting sleeve 11, crossbeam lower plate 20, swing arm peace Shelve 30, towing hook 40, acoustic filter suspension hook 50, installation position 60, line card seat 70, stabilizer bar arm 80.

Embodiment is substantially as shown in Figure 1 and Figure 2：A kind of subframe assembly, including crossbeam upper plate, crossbeam lower plate 20, bracket peace Dress axle sleeve 11, swing arm installing rack 30 and cold stamping shaped n shapes collar tie beam 10.Stabilizer bar arm 80 and swing arm installing rack 30 are distinguished Weld with n shapes collar tie beam 10.

The edge of crossbeam upper plate and edge matching, the end face of bracket mounting sleeve 11 is provided with lines, and lines is zigzag.

The inner side of n shapes collar tie beam 10 is welded with six line card seats 70, is wherein provided with a line on the left crossbeam of n shapes collar tie beam 10 Deck 70, is provided with two line card seats 70 on the right crossbeam of n shapes collar tie beam 10, the entablature of n shapes collar tie beam 10 is provided with three line card seats 70.Towing hook 40 is also equipped with the entablature of n shapes collar tie beam 10, n shapes collar tie beam 10 is provided with the installation position 60 for installing attenuator. The installation position 60 is heavy plane in, and is designed with bolt hole.Acoustic filter suspension hook 50 is installed in crossbeam lower plate 20.In addition, horizontal Support bar is installed between beam upper plate and crossbeam lower plate 20.

In the subframe assembly of this programme, main load bearing component n shapes collar tie beam 10 largely overcomes biography using cold stamping shaped The collar tie beam of system is formed the defect of presence by crossbeam and longitudinal beam welding, substantially increases its fatigue strength.Bracket mounting sleeve 11 End face designs lines, substantially increases its fixed performance and positioning precision.

Above-described is only embodiment of the present utility model, the general knowledge here such as known concrete structure and characteristic in scheme Excessive description is not made.It should be pointed out that for a person skilled in the art, in the premise without departing from this utility model structure Under, some deformations and improvement can also be made, these should also be considered as protection domain of the present utility model, and these are all without impact Effect and practical applicability that this utility model is implemented.This application claims protection domain should be with the content of its claim It is defined, specific embodiment in description etc. records the content that can be used for explaining claim.
