Abstract
The utility model provides a balance axle shell and a plate-spring bolt clamping plate. The balance axle shell is added with bolt clamping lugs to fasten the plate spring; the plate spring bolt clamping plate is added with two holes for mounting the bolt clips of the fixed plate spring. Thereby, the number of bolt clips fixed on the balance axle shell increases from the original two to four. As a result, the stress received by the plate spring becomes more even, and the loaded area of the balance axle shell is increased. Thereby, the breakage of the balance shaft shell and the rupture of the plate spring can be effectively avoided. The utility model has the advantages of rational structure, high strength, reliable safety, etc.
Description
Technical field
The utility model belongs to automobile zero one, specifically is a kind of HD truck balance shaft housing and laminated spring bolt card pressing plate.
Background technology
At present, HD truck (as vehicles such as Steyr, Ou Man) balance shaft housing, the middle part of balance shaft housing is a dress balance axis hole, there are four holes that are used to adorn the bolt card of adapter plate spring the both sides in hole, the hole of balance axis hole and bolt card makes thinner that the two side of balance shaft housing becomes, in addition, laminated spring relies on two bolt cards (each bolt card is " U " shape two bolts) and two laminated spring bolt card pressing plates that have the groove of circular arc, and the hole of passing the balance shaft housing both sides by bolt is fixed on laminated spring on the balance shaft housing.This balance shaft housing and laminated spring bolt card pressure plate structure, when HD truck in the road in mountain road and engineering construction building site, since in full load in the effect that is subjected to rough road influence and impulsive force, often take place that balance shaft housing breaks or phenomenon such as laminated spring fracture, cause train operation accident sometimes, cause heavy economic losses.
Summary of the invention
The purpose of this utility model overcomes the deficiency that above-mentioned prior art exists, HD truck balance shaft housing and laminated spring bolt card pressing plate are carried out structural development, provide a kind of rational in infrastructure, the intensity height can prevent effectively that balance shaft housing from breaking or the HD truck balance shaft housing and the laminated spring bolt card pressing plate of laminated spring fracture.
Skill scheme of the present utility model for achieving the above object is such:
A kind of HD truck balance shaft housing, the middle part of housing is the hole of dress balance shaft, there are four holes that are used to adorn the bolt card of adapter plate spring the both sides in hole, it is characterized in that: the outer both sides parallel with the hole of bolt card of described housing are respectively equipped with the bolt card ear that is used to adorn the adapter plate spring, have the groove of circular arc on the bolt card ear.
A kind of laminated spring bolt card pressing plate of HD truck has the groove of circular arc on the laminated spring bolt card pressing plate, it is characterized in that: one side described laminated spring bolt card pressing plate be provided with two holes that are used to adorn the bolt card of adapter plate spring.
A kind of HD truck balance shaft housing of the present utility model and laminated spring bolt card pressing plate, because balance shaft housing has increased the bolt card ear of dress adapter plate spring, laminated spring bolt card pressing plate has increased by two holes that are used to adorn the bolt card of adapter plate spring, so just make and be fixed on the used bolt card of laminated spring on the balance shaft housing, by two original bolt cards, change into and use four bolt cards, thereby make the stressed more even of laminated spring, balance shaft housing structural bearing area is strengthened, can prevent effectively that thus balance shaft housing from breaking or the laminated spring fracture, it is more reasonable that they have structure, intensity height, advantage such as safe and reliable.

Fig. 1 is a kind of balance shaft housing front view of HD truck;
Fig. 2 is a kind of balance shaft housing birds-eye view of HD truck;
Fig. 3 is a kind of balance shaft housing upward view of HD truck;
Fig. 4 is a kind of laminated spring bolt card pressing plate front view of HD truck;
Fig. 5 is a kind of laminated spring bolt card pressing plate lateral plan of HD truck;
Fig. 6 is a kind of balance shaft housing and laminated spring bolt card pressing plate assembling scheme drawing of HD truck.
The specific embodiment
Be elaborated below in conjunction with accompanying drawing:
Fig. 1, Fig. 2 and shown in Figure 3, a kind of HD truck balance shaft housing, the middle part of balance shaft housing 1 is the hole 2 of dress balance shaft, there are four holes 3 that are used to adorn the bolt card of adapter plate spring the both sides in hole, the outer both sides parallel with the hole of bolt card of described housing are respectively equipped with the bolt card ear 4 that is used to adorn the adapter plate spring, have the groove 5 of circular arc on the bolt card ear.The bolt card ear strengthens balance shaft housing structural bearing area, has improved load-carrying capacity, can prevent that balance shaft housing from breaking.
Fig. 4 and shown in Figure 5, a kind of laminated spring bolt card pressing plate of HD truck, laminated spring bolt card pressing plate 6 and the supporting use of balance shaft housing, the groove 7 that has circular arc on the laminated spring bolt card pressing plate, one side described laminated spring bolt card pressing plate be provided with two holes 8 that are used to adorn the bolt card of adapter plate spring.
Shown in Figure 6, be a kind of balance shaft housing and laminated spring bolt card pressing plate assembling scheme drawing of HD truck.Laminated spring 9 overlays on the balance shaft housing 1, and is fixing by four bolt cards 10, two by on be pressed in the groove of circular arc of laminated spring bolt card pressing plate 67, pass the hole 3 of bolt card on the balance shaft housing, tighten with nut 11; Article two, by placing down in the groove 5 that has circular arc on the balance shaft housing 1 on the bolt card ear, and pass hole on the laminated spring bolt card pressing plate, use nut screwing clamping; So just use four bolt cards that laminated spring is fixed on the balance shaft housing, made the stressed more even of laminated spring, can prevent the laminated spring fracture thus.
