Abstract
The utility model relates to a balance suspension being applicable to a heavy-duty truck, which comprises a balance shaft support, a core shaft, a plate spring bracket and a connecting shaft. The balance suspension is characterized in that the connecting shaft is an integral independent crank shaft structure which is bent downward by 63mm from the middle part, is shaped like a saddle and has an I-shaped cross section, and six reinforcing ribs are evenly distributed at the lower part of a mounting surface at the junction of the balance shaft support and a frame, while the lower part of the mounting surface is positioned on the outer side of the wall thickness of the support. The balance suspension well solves the problems that the cracking frequently occurs on the mounting surface of the balance shaft support at the junction with the frame when in the working condition of the balance suspension of the heavy-duty truck, the connecting shaft interferes with a vehicle drive shaft, the connecting shaft is broken and the like.
Description
Technical field
The utility model relates to a kind of balance suspension that is applicable to heavy duty truck.
Background technology
The rear suspension of heavy duty truck adopts equalizing suspension system more now, and the back axle wheel is equated by vertical load in the assurance.In balance suspension, generally all have one to connect or the open circuited balance shaft in the left and right sides, left and right sides trunnion base is realized balance shaft by lining and adapter shaft location be connected.
At present, introduce Korea S's technology 468 constitutional balance suspension systems newly developed owing to be subjected to the restriction of structure, many phenomenons such as the trunnion base attachment face cracking that occurs continually connecting to ground under bad working environments and locate, adapter shaft and propeller-shaft interference and adapter shaft fracture.
Summary of the invention
For adapter shaft that solves existing truck balance suspension and problems such as propeller-shaft interference and adapter shaft fracture, the utility model provides a kind of balance suspension that is applicable to heavy duty truck.
Realize that the above-mentioned purpose design plan is as follows:
A kind of balance suspension of heavy duty truck that is applicable to comprises symmetrically arranged trunnion base, mandrel and leaf spring bracket, also comprises adapter shaft; Described adapter shaft is that the middle part is bent downwardly and is saddle and the disconnected cross section whole independent crankshaft structure for " worker " font; The tie bolt place of described trunnion base and vehicle frame attachment face is laid with six roots of sensation reinforced rib.
Described adapter shaft middle part is bent downwardly 63mm.
Described reinforced rib knuckle is R10.
Described trunnion base wall thickness is 16mm.
Useful technique effect of the present utility model is embodied in following several aspect:
1. adapter shaft of the present utility model is improved to the whole independent crankshaft structure of disconnected cross section for " worker " font face by the real axis joint in original two ends welding band torsion bar hole, increase adapter shaft intensity widely, and the adapter shaft middle part is designed to be bent downwardly, and has eliminated adapter shaft and propeller-shaft interference.
2. the flange face bottom at the trunnion base place of connecting to ground is positioned at bearing wall thickness outer side edges rectangular distribution six roots of sensation reinforced rib, and the reinforced rib knuckle is increased to R10 by original R5, and the trunnion base wall thickness is increased to 16 by original 12, increases the balance suspension load-carrying capacity.Show that through operation result original balance suspension probably travels and just occurs the bearing cracking phenomena about 10,000 kilometers before improving, and can guarantee after the improvement to travel more than 50,000 kilometers, has prolonged service life widely.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is that A is to partial enlarged drawing.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
The utility model comprises symmetrically arranged trunnion base 1, mandrel 2, leaf spring bracket 3 and adapter shaft 4; Adapter shaft 4 is saddle for the middle part is bent downwardly and disconnected cross section is the whole independent crankshaft structure of " worker " font, and the adapter shaft middle part is bent downwardly 63mm.Trunnion base 1 is laid with six roots of sensation reinforced rib with the tie bolt place of vehicle frame attachment face, and the reinforced rib knuckle is R10.The trunnion base wall thickness is 16mm.
Two trunnion bases 1 about symmetrically arranged, the outside, its underpart is provided with the connecting bore that is used for installing with propelling rod usefulness, so that implement the installation of propelling rod; The inboard is provided with the mating holes with the assembling of the solid axle at adapter shaft 4 two ends, before adapter shaft 4 trunnion bases 1 are installed, remove earlier the adapter shaft axle head and the hole that matches with it in greasy dirt, evenly smear locking glue then, trunnion base 1 adapter shaft 4 is fixed on together, after locking gelling admittedly, with locking pad and lock pin location; As the assembling parent, implement the component assembly of postorder assembly with this assembly unit.Be provided with the mounting hole that is used for mandrel 2 assemblings at trunnion base 1 middle part; Mandrel 2 is the net-size forging of band blind hole, and an end and trunnion base 1 are fixing, and the other end and leaf spring bracket 3 are fixing, and leaf spring bracket 3 outsides have balance shaft tightening cover and hubcap to be fixed; Trunnion base 1 top flange face is provided with the mounting hole that is used to connect to ground, so that implement being connected of whole machine balancing suspension and vehicle frame after the assembling.
The utility model had both improved the load-carrying capacity of balance shaft assembly, had reduced the weight of self again.
