Abstract
The utility model discloses a balance shaft assembly of breakaway reactive suspension, comprising a bracket, a balance shaft and a balance shaft casing. One end of the balance shaft is fixed to the bracket, while the other end is rotatablely connected to the balance shaft casing. The beneficial effect of the utility model includes: having compact structure, light weight, low cost, good performance, big loading amount, simple structure, easy producing and arrangement. As the interference point of the original suspension is eliminated, so as to obviously increase the tick volume of the through type driving axel, thus the overloading frequency of the driving axle because of limiting is greatly reduced, so that the use life of the related components of the driving axle are prolonged. The perfect matching of the utility model, the road spring and the rubber plinth makes the shock resistance and the ride of the mobile greatly improved, increases the conformability of the driver, reduces the fault rate of goods, and improves the reliability and use life of the frame.
Description
(1) technical field
The utility model relates to a kind of automobile balance shaft assembly, particularly a kind of balance shaft assembly of breakaway-element balance suspension.
(2) background technology
The core component of automobile balance suspension system is a balance shaft assembly.Balance shaft is whole through, connects because balance shaft is whole, makes balance shaft assembly weight strengthen, and vehicle economy descends; In addition, if the balance shaft angle of assembling has improper easily causing to interfere with transmission shaft slightly.The integral type balance shaft is a heavy forging, and its hot working, cool working and heat treatment all need special equipment, and all shortcoming has all caused the balance shaft assembly poor-performing, production efficiency is low, cost is high for this.
(3) summary of the invention
The technical problems to be solved in the utility model is: the utility model provide a kind of carry big, dependable performance, simple in structure, produce and assembling easily, the balance shaft assembly of breakaway-element balance suspension that cost is low.
In order to solve the problems of the technologies described above, the utility model comprises support, balance shaft and balance shaft housing, and described balance shaft one end and support are fixed, and the other end and balance shaft housing are rotatably connected.
In order to reduce weight, blind hole is arranged in the middle of the described balance shaft.
For the ease of installing, reduce used intermediate connector is installed, further alleviate assembly weight, described support top is provided with the connecting bore that is used to connect to ground, the support bottom is provided with and is used for and the lower thrust rod connecting bore, and balance shaft housing is provided with leaf spring draw-in groove and leaf spring gripping mechanism.
In order to improve reliability and load-carrying capacity, described balance shaft is connected by globe bearing with balance shaft housing.
The beneficial effects of the utility model are: the utility model compact conformation, in light weight, cost is low, performance good, carrying is big, simple in structure, be convenient to produce and install.Owing to eliminated the interference point of original suspension, the jerk value of back axle significantly strengthens in making, so just greatly reduces drive axle because of spacing frequency of transshipping, thereby has prolonged the service life of drive axle associated components.Because the perfection of the utility model and leaf spring, rubber plinth coupling makes the impact resistance of vehicle and ride comfort improve greatly, strengthen occupant's traveling comfort again, reduced the probability of damage of goods, improved the reliability and the life-span of vehicle frame.

(5) specific embodiment
A kind of specific embodiment as shown in Figure 1 and Figure 2, it comprises support 3, balance shaft 4 and balance shaft housing 9.Balance shaft 4 is the middle net-size forging that blind hole is arranged.Support 3 tops are provided with the connecting bore that is used to connect to ground, and the bottom is provided with and is used for and the lower thrust rod connecting bore, and the middle part is provided with balance shaft 4 mounting holes, and balance shaft 4 one ends and support 3 are fixing, and the other end is connected by globe bearing 13 with balance shaft housing 9.Balance shaft housing 9 is provided with leaf spring draw-in groove and leaf spring gripping mechanism, and the outer end of balance shaft housing 9 is provided with cap 18.
Installation method of the present utility model: with support 3 is the assembling parent, at first smears bonding glue at support 3 endoporus, then balance shaft 4 is seated, and squeezes into straight pin 19 location after the glue solidifies.Again type ring 6 is contained in the bearing oil capping 8 inner ring of on balance shaft 4, pack into successively then seal ring 5, bearing oil capping 8 and globe bearing 13; In two bearing holes of balance shaft housing 9, be respectively charged into the outer ring of globe bearing 13, the Simmer ring 7 of in the Simmer ring hole, packing into again, then the balance shaft housing 9 that installs is contained on the balance shaft 4, refill dividing bush 17, space washer 16 and globe bearing 13 inner rings, install behind the inner ring bearing briquetting 15 and balance shaft 4 is fixing with bolt 14.After above-mentioned assembling is finished, on balance shaft housing 9 outer faces, smoothen sealant again, with bolt 11 that cap 18 and balance shaft housing 9 is fixing, realize sealing.Utilize filler port to add lubricating oil after assembly assembling finishes and realize lubricatedly, open air bleed hole during oiling, add and tighten hex bolt 10 behind the oil and taper thread hexagonal socket head plug 12 keeps sealing.
The utility model uses in pairs, is installed in the both sides of vehicle frame respectively, makes between two balance shafts 4 at regular intervalsly, forms the breakaway-element structure, can not interfere with propeller-shaft.
After the utility model entrucking, leaf spring is assemblied in the draw-in groove of balance shaft housing 9, and urgent then bolt 2 and flat gasket 1 clamp leaf spring.
