Abstract

The utility model discloses a disconnected balance shaft suspension, which comprises a left balance shaft bracket, a right balance shaft bracket and a balance shaft. The improvement is as follows: the balance shaft consists of a left balance shaft and a right balance shaft; both the left balance shaft and the right balance shaft are in a split type structure and are independent; the left balance shaft is sleeved in the left balance shaft bracket; and the right balance shaft is sleeved in the right balance shaft bracket. The disconnected balance shaft suspension has the beneficial technical effects that the balance shaft in an integral structure is improved into two sections of independent balance shafts; therefore, an arc-shaped structure at the middle part is eliminated, the manufacturing difficulty of the balance shaft is reduced, and the manufacturing cost is also correspondingly reduced; the structure of the balance shaft is simplified so as to be convenient to mount; the interference problem between the balance shaft and the other parts and particularly between the balance shaft and a transmission shaft is avoided, and the disconnected balance shaft suspension can be applicable to axle structures with different types; moreover, the weight of the balance shaft is also reduced.

Description

Breakaway-element balance shaft suspension

Technical field

The utility model relates to a kind of balance shaft suspension, relates in particular to a kind of breakaway-element balance shaft suspension.

Background technology

Balance shaft on the back balance axle suspension frame of existing heavy motor vehicle adopts one-piece construction, and this balance shaft is shaped as: the balance shaft two ends are cylindrical structure, and the middle part is an arch configuration, and the cylinder at two ends connects through arch configuration; Cylindrical structure and arch configuration are solid forging, need special equipment to process, and be with high costs; And the balance shaft installation is inconvenient, and arch configuration is easy to and transmission shaft generation frictional interference; This integrally-built balance shaft can't mate dissimilar vehicle bridge, can only the corresponding a kind of balance shaft of a kind of vehicle bridge.

The utility model content

To the problem in the background technology, the utility model provides a kind of breakaway-element balance shaft suspension, comprise left balance shaft support, right balance shaft support and balance shaft; Its improvement is: said balance shaft is made up of left balance shaft and right balance shaft, and left balance shaft and right balance shaft are split-type structural and separate, and left balance sleeve is connected in the left balance shaft support, and right balance sleeve is connected in the right balance shaft support.

The useful technique effect of the utility model is: integrally-built balance shaft is improved to two sections independently balance shafts, has cancelled the arch configuration at middle part, reduced the manufacture difficulty of balance shaft, make the also corresponding reduction of cost of manufacture; Simplified the balance shaft structure, be convenient to install, avoided balance shaft and miscellaneous part especially with the interference problem of transmission shaft, can adapt to dissimilar vehicle bridge structures; The weight of balance shaft is also alleviated.

Description of drawings

The structural representation of Fig. 1, the utility model;

Among the figure, steel spring 5, saddle clamp 6, balance shaft crossbeam 7.

The specific embodiment

The structure of the utility model is: comprise left balance shaft support 1, right balance shaft support 2 and balance shaft; Its improvement is: said balance shaft 3 is made up of with right balance shaft 4 left balance shaft 3, and left balance shaft 3 is a split-type structural and separate with right balance shaft 4, and left balance shaft 3 is socketed in the left balance shaft support 1, and right balance shaft 4 is socketed in the right balance shaft support 2.

The balance shaft of this two sectional type structure; The connecting portion of the arch configuration in the middle of having saved has thoroughly been avoided balance shaft itself and the possibility that miscellaneous part interferes, and the weight of balance shaft is alleviated; The difficulty of making is reduced, and cost has also obtained reduction thereupon.

The peripheral components relevant with the utility model has: the upper surface of left balance shaft support 1 and right balance shaft support 2 is connected with the downside at balance shaft crossbeam 7 two ends respectively; Saddle clamp 6 is enclosed within steel spring 5 middle parts hoops on the equalizer bearing hub, the equalizer bearing hub with the force transmission of steel spring 5 on left balance shaft 3 and right balance shaft 4.

Claims

1. a breakaway-element balance shaft suspension comprises left balance shaft support (1), right balance shaft support (2) and balance shaft; It is characterized in that: said balance shaft is made up of left balance shaft (3) and right balance shaft (4); Left side balance shaft (3) and right balance shaft (4) are split-type structural and separate; Left side balance shaft (3) is socketed in the left balance shaft support (1), and right balance shaft (4) is socketed in the right balance shaft support (2).
