Abstract
The utility model discloses a balanced suspension structure, including balanced suspension support, axle assembly, leaf spring, still include distance rod and distance rod support, the distance rod support is fixed on the axle assembly, the both ends of distance rod are articulated with balanced suspension support and distance rod support through the round pin axle respectively, the axis and the contained angle of water flat line of distance rod are 0 ~ 3, and the leaf spring is at the compressive deformation in-process, and the one end of being connected with the distance rod support on the distance rod is less than the one end of being connected with balanced suspension support all the time. The balanced suspension structure optimizes the working angle of the lower thrust rod, reduces the vertical component force of the thrust rod, and strengthens the key bearing part, so that the suspension is suitable for a drive axle group of a heavy special chassis.
Description
Technical Field
The utility model belongs to the technical field of heavy special type vehicle chassis technique and specifically relates to a balanced suspension structure.
Background
The tandem type steel plate spring balance suspension structure with the common structure is mainly used for trailers, the trailers are non-drive axles, and when the tandem type steel plate spring balance suspension structure is used for a drive axle group of a heavy special chassis, the defects that the structure is not suitable and the lower thrust rod is easy to lose efficacy and deform are exposed. As shown in figure 2, the rear end of a lower thrust rod of an original structure is arranged on a lower pressing plate of a U-shaped bolt of a plate spring of a fixed axle, and the included angle between the axis of the thrust rod and the horizontal line is more than 16 degrees, so that when the same horizontal thrust is carried out, the structure can generate larger vertical component force to the thrust rod, the stress of the thrust rod is remarkably increased, the size of an installation pin shaft or a bolt pin is phi 16mm, the requirement on the strength applied to a drive axle cannot be met, and the shaft sleeve part of the thrust rod can lose efficacy and deform.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a balanced suspension structure is proposed, this balanced suspension structure has optimized the working angle of lower thrust rod, has reduced the vertical component of thrust rod, has strengthened the key bearing position simultaneously, makes this type of suspension be applicable to the transaxle group on heavy special chassis.
The utility model provides a balanced suspension structure, includes balanced suspension support, axle assembly, leaf spring, still includes distance rod and distance rod support, the distance rod support is fixed on the axle assembly, the both ends of distance rod are articulated with balanced suspension support and distance rod support through round pin axle respectively, the axis of distance rod is 0 ~ 3 with the contained angle of water flat line, and the leaf spring is at the compressive deformation in-process, and the one end of being connected with the distance rod support on the distance rod is less than the one end of being connected with balanced suspension support all the time.
Preferably, the pin shaft is a pin shaft with a diameter phi of 36 mm.
Preferably, in the above technical solution, the thrust rod is of a telescopic structure.
The beneficial effects of the utility model reside in that:
this balanced suspension structure simply changes on current general balanced suspension device structure basis of trailer product, can realize satisfying the application of the transaxle group on heavy special type chassis, has developed a simple structure, is fit for mass production, the better novel balanced suspension structure of economic nature for the transaxle group of heavy special type car, and rated axle load can reach 13T/axle. Low implementation cost and great effect, and is suitable for wide-range popularization and application.

Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of a prior art structure described in the background art.
The reference numbers are as follows: 1-balanced suspension support, 2-axle assembly, 3-plate spring, 4-thrust rod, 5-thrust rod support and 6-pin shaft.
Detailed Description
The technical solution of the present invention is clearly and completely described below with reference to the accompanying drawings of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
The balanced suspension structure shown in fig. 1 comprises a balanced suspension support 1, an axle assembly 2, a plate spring 3, a thrust rod 4 and a thrust rod support 5, wherein the thrust rod support 5 is fixed on the axle assembly 2, two ends of the thrust rod 4 are respectively hinged to the balanced suspension support 1 and the thrust rod support 5 through a pin shaft 6, an included angle between the axis of the thrust rod 4 and the horizontal line is 0-3 degrees, and in the compression deformation process of the plate spring 3, one end, connected with the thrust rod support 5, of the thrust rod 4 is always lower than one end, connected with the balanced suspension support 1, of the plate spring.
In this embodiment, the pin 6 has a diameter of phi 36 mm.
Preferably, the thrust rod 4 is of a telescopic structure.
The main improvement of this embodiment over the balanced suspension structure in fig. 2 in the prior art is: 1. the thrust rod support 5 used for being connected with the thrust rod 4 on the axle assembly 2 moves upwards, the included angle between the axis of the thrust rod 4 and the horizontal line is greatly reduced and adjusted to 0-3 degrees, and compared with a structure that the included angle between the axis of the thrust rod 4 and the horizontal line is larger than or equal to 16 degrees in the prior art, under the action of the same effective horizontal force, the stress of the thrust rod 4 is remarkably reduced in the embodiment. In the compression deformation process of the plate spring 3, one end of the thrust rod 4 connected with the thrust rod support 5 is always lower than one end connected with the balanced suspension support 1, so that a downward acting force is not generated on the balanced suspension support 1; 2. the size of the pin shaft 6 is increased from phi 16mm to phi 36mm, so that the bearing strength of the balanced suspension is obviously improved integrally. In fig. 1, a is an included angle between the axis of the thrust rod 4 and the horizontal line in this embodiment, the thrust rod support 5 is a conventional technology, a specific structure thereof is not specifically described here, and all supports suitable for this scheme are within the protection scope of the present invention. In this embodiment, the thrust rod 4 is of a telescopic structure, and a rod member of a telescopic structure is a prior art, which is not described in detail herein.
This balanced suspension structure simply changes on current general balanced suspension device structure basis of trailer product, can realize satisfying the application of the transaxle group on heavy special type chassis, has developed a simple structure, is fit for mass production, the better novel balanced suspension structure of economic nature for the transaxle group of heavy special type car, and rated axle load can reach 13T/axle. Low implementation cost and great effect, and is suitable for wide-range popularization and application.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
