本发明公开了一种断开式平衡悬架的平衡轴总成，本发明包括支架、平衡轴和平衡轴壳，所述平衡轴一端与支架固定，另一端与平衡轴壳可转动连接。本发明的有益效果是：本发明结构紧凑、重量轻、成本低、性能好、承载大，结构简单，便于生产和安装。由于消除了原有悬架的干涉点，使得中后桥的跳动量显著加大，这样就大大降低了驱动桥因限位而过载的频率，从而延长了驱动桥相关部件的使用寿命。又由于本发明和板簧、橡胶支座的完美匹配使得车辆的抗冲击性和平顺性大大提高，增强了乘员的舒适性，降低了货物的损坏概率，提高了车架的可靠性和寿命。
The invention discloses a balance shaft assembly of a disconnected balance suspension. The invention comprises a bracket, a balance shaft and a balance shaft housing. One end of the balance shaft is fixed to the bracket, and the other end is rotatably connected to the balance shaft housing. The beneficial effects of the present invention are: the present invention is compact in structure, light in weight, low in cost, good in performance, large in load, simple in structure, and convenient for production and installation. Due to the elimination of the interference point of the original suspension, the jump of the middle and rear axles is significantly increased, which greatly reduces the frequency of overloading of the drive axle due to the limit, thereby prolonging the service life of the relevant components of the drive axle. In addition, due to the perfect matching of the invention with the leaf spring and the rubber bearing, the impact resistance and smoothness of the vehicle are greatly improved, the comfort of the occupants is enhanced, the probability of cargo damage is reduced, and the reliability and life of the vehicle frame are improved.
Description
(1) technical field
The present invention 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 problem to be solved in the present invention is: the invention provides 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 present invention includes support, balance shaft and balance shaft housing, 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 invention has the beneficial effects as follows: compact conformation of the present invention, 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 present invention 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.
(4) description of drawings
Fig. 1 is a structural representation of the present invention; Fig. 2 is that cutaway view is looked on the left side of Fig. 1;
Among the figure: 1, flat gasket, 2, bolt, 3, support, 4, balance shaft, 5, seal ring, 6, the type ring, 7, Simmer ring, 8, bearing oil capping, 9, balance shaft housing, 10, hex bolt, 11, bolt, 12, the taper thread hexagonal socket head plug, 13, globe bearing, 14, bolt, 15, the bearing briquetting, 16, space washer, 17, dividing bush, 18, cap, 19, straight pin.
(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 invention: 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 present invention 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 entrucking of the present invention, 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.
