Abstract

The utility model relates to a balance suspension. Two ends of a balance shaft respectively insert into shaft holes arranged at the upper end of a left bracket and right bracket and fixed tightly by bolts and dowels. Shaft stubs at the two ends are respectively fixed tightly with shaft holes by the dowels and the bolts. Oil seals are pressed into an oil seal collar of the bracket. Composite bushings are sleeved on the shaft stubs. The ends of the shaft stubs are provided with shaft stub briquettings. The shaft stubs and the shaft stub briquettings are fixed tightly through the bolts and the dowels. End housings and shaft housings are fixed tightly through the bolts. The bottom of the shaft housing is provided with bent neck lubricating nipples. The balance suspension utilizes the connection structure, thereby eliminating stress concentration of supporting positions, enhancing the strength, improving the elasticity, avoiding breaking the shaft. A lubrication mode of a balance shaft assembly utilizes lubricating grease instead of lubricating oil; accordingly the problem of oil leakage of the balance shafts is resolved. The shaft housings and brackets are subjected to structure optimization, and the structure is more reasonable, the dead weight is much lighter under the condition of meeting requirements for use.

Description

Balance suspension

Technical field

The utility model relates to a kind of heavy motor vehicle parts, specifically relates to a kind of balance suspension.

Background technology

Balance suspension is widely used on the heavy motor vehicle, it has improved the ground connection property of the particularly heavy special-use vehicle tire of heavy motor vehicle, guaranteed the harmony of load between two bridges under the various operating modes or the many bridges, in two bridge balance suspension light plate spring handle load mean allocation are given, back axle.

But mainly there are several problems in balance suspension of the prior art, and elasticity is relatively poor, easy off-axis, and cost is higher, and leakage of oil etc.

The utility model content

In order to solve the problems of the technologies described above, the utility model provides a kind of balance suspension rational in infrastructure.

The technical solution adopted in the utility model is as follows:

Balance suspension, insert respectively in the axis hole of support upper end, the left and right sides at the balance shaft two ends, fastening by bolt and pin, the two ends spindle nose respectively with support bottom axis hole by pin and bolted, oil sealing is pressed in the support oil sealing shelves, composite bush is enclosed within on the spindle nose, the spindle nose end is provided with the spindle nose briquetting, spindle nose and spindle nose briquetting are by bolt and pin locking, and end cap is fastening by bolt and axle housing, and the axle housing lower end is provided with curved neck lubrication adapter.

The utility model balance suspension has the following advantages:

By this connection structure, eliminated the stress concentration at supporting position, increase intensity, increased elasticity, prevent off-axis.

Adopt copper sheathing to cooperate between balance shaft assembly axle housing and the spindle nose, than common bearing cooperate cost lower, keep in repair also convenient.

The balance shaft assembly lubricating method adopts grease to replace lubricating oil, has thoroughly solved the leakage of oil problem of balance shaft.

Axle housing and support are satisfying more reasonable structure under the situation of operating needs through framework optimization, and it is lighter to conduct oneself with dignity.
