Abstract

A kind of combined balance shaft axle housing, is characterized in that, be made up of the upper body part (1) that can separate and lower body part (3); Wherein said upper body (1) part is spring perch part, and described lower body part (3) is balance shaft mounting hole and U-bolt fastening part; Upper body part (1) and lower body part (3) are fixed as entirety by locating dowel pin (2).The utility model is ensureing under the prerequisite that balance shaft axle housing is outside and connection relation is constant, by balance shaft axle housing is become from entirety the two parts combined up and down, avoid the defect that conventional balanced axle axle housing needs integral replacing after spring perch location contacts quenching surface wear, for user reduces maintenance cost.

Description

Combined balance shaft axle housing

Technical field

The utility model relates to the two rear-axle balance suspension system of heavy motor vehicle, and particularly, the utility model relates to two rear-axle balance suspension balance shaft axle housing used.

Background technology

Increasingly mature along with Chinese logistics carrier, for the consideration improving running income, people day by day pay close attention to the technology that heavy duty truck reduces maintenance cost.Traditional balance shaft axle housing is generally integrated parts, and as shown in Figure 2 and Figure 3, in use due to after spring perch location contacts quenching surface wear, need integral replacing balance shaft axle housing, cost expenses is larger.

Utility model content

In order to avoid the two rear-axle balance suspension balance shaft axle housing used of heavy duty truck, due to the wearing and tearing of spring perch position, entirety is scrapped, the novel combined balance shaft axle housing providing the split of a kind of replaceable upper steel plate spring holder of this application.

For achieving the above object, the utility model proposes a kind of combined balance shaft axle housing, be made up of the upper body part 1 that can separate and lower body part 3; Wherein said upper body 1 part is spring perch part, and described lower body part 3 is balance shaft mounting hole and U-bolt fastening part; Upper body part 1 and lower body part 3 are fixed as entirety by locating dowel pin 2.

Further, described upper body part 1 contacts with the steel spring of automobile.

Further, described locating dowel pin is 2, and is symmetrical arranged.

Further, described lower body part 3 comprises 2 groups of U-bolt fastening parts.

The utility model combined balance shaft axle housing is on the architecture basics of existing cast steel balance shaft axle housing, at suitable position, is divided into upper and lower two parts, and can according to the demand difference of technique in production process or combinations produce.

Improvement effect of the present utility model is exactly: ensureing under the prerequisite that balance shaft axle housing is outside and connection relation is constant, by balance shaft axle housing is become from entirety the two parts combined up and down, avoid the defect that conventional balanced axle axle housing needs integral replacing after spring perch location contacts quenching surface wear, for user reduces maintenance cost.

In addition, for traditional balance shaft axle housing, when carrying out Quenching Treatment to the spring perch position contacted with automobile leaf spring, Quenching Treatment to be carried out to the part of entirety, comparatively wasting time and energy.And when carrying out Quenching Treatment to balance shaft axle housing of the present utility model, only need to operate the corresponding site of upper body part, reduce working strength, improve work efficiency.

Fig. 3 is the axial schematic diagram of conventional balanced axle axle housing structure;

Fig. 4 is the structural representation of the utility model combined balance shaft axle housing.

Detailed description of the invention

Composition graphs 4 pairs of combined balance shaft axle housings are further described.As shown in Figure 4, combined balance shaft axle housing is Split type structure, by being separated on traditional integral formula balance shaft axle housing with the spring perch part of steel spring contact friction, balance shaft axle housing is become comprise the Split type structure of upper body 1 (with the spring perch part of steel spring contact friction) and lower body 3 (balance shaft mounting hole and U-bolt fastening part).Shown in composition graphs 1, when assembling, balance shaft axle housing upper body 1 and balance shaft axle housing lower body 3 is made to guarantee equalizing suspension system positioning requirements with the form of entirety by locating dowel pin 2, the after date when operation one section, when comparatively galling appears in the spring perch part with steel spring contact friction, the guide function of leaf spring is reduced to and allows lower prescribing a time limit, replaceable balance shaft axle housing upper body 1, and without the need to changing balance shaft axle housing lower body 3, thus reduce vehicle maintenance cost.

Although the utility model have employed two-piece unit structure, still utilize the outside connection parts of conventional balanced axle axle housing, only used two symmetrical locating dowel pins 2, simplify process requirements.

The utility model is by changing the processing technology of balance shaft axle housing, change traditional balance shaft axle housing into two-piece unit structure by entirety, the independent assortment of manufacturer's different balance shaft axle housing product can be realized, reduce the casting die preparatory period, reduce heat processing unit volume, enhance productivity.Meanwhile, contacting and topside more easy to wear with steel spring by changing, avoiding changing whole balance shaft axle housing, be conducive to the maintenance cost reducing vehicle, reduce social resources consumption.
