Description
Technical field
The invention belongs to the exploitations of automobile drive axle components to design, more particularly, to a kind of through drive with lubricating function
The perforation bearing housing of dynamic bridge jackshaft.
Background technique
With the development and progress of domestic mechanical industry level, commercial vehicle field is to the high-quality of product, highly reliable, low
More stringent requirements are proposed for the indexs such as carbon, environmental protection.Driving axis is as one of big assembly of commercial vehicle three, performance indicator, can
It is also presented by property index and significantly promotes trend.To realize the highly reliable, high durable of driving axis, to gear, bearing
More stringent requirements are proposed for greasy property, and especially the jackshaft of tandem axles penetrates through axle bearing, which relies on from mantle
Gear rotates the oil lubrication stirred, but since it is in the extreme higher position in axle assembly, and have one with driven wheel of differential
Determine offset distance, cause in vehicle low speed or descending operating condition, there are the risks of insufficient lubrication for the bearing, and bearing early stage is caused to be lost
Effect.Traditional lubrication system is no longer satisfied increasing reliability index requirements.
Summary of the invention
The perforation bearing housing of the object of the present invention is to provide a kind of drive axle jackshaft with lubricating function, the bearing block
Installation space and support strength can not only be provided for bearing, sufficient lubricating oil can also be provided for bearing, guarantee perforation axis axis
Hold the lubrication needs under various operating conditions.
The object of the present invention is achieved like this, in conjunction with attached drawing:
A kind of perforation bearing housing of the drive axle jackshaft with lubricating function, by bearing block 1, oil baffle 2, oil duct 3, collection
Oil groove 4 is constituted；The bearing block 1 is equipped with the through hole for installing bearing and 1 bottom of bearing block is flaunching structure, oil baffle 2
Through hole and the flaunching structure junction of bearing block 1 are set, and oil duct 3 is provided in 1 through hole of bearing block, and 3 one end of oil duct connects
Oil baffle 2 is connect, 3 other end of oil duct is connected to oil trap 4, and oil trap 4 is arranged in 1 flaunching structure bottom of bearing block.Due to driven
There is certain offset distance between bevel gear and perforation axle bearing, the lubricating oil that it is stirred cannot be directly thrown on bearing in low speed,
And the design of bearing block through the invention, structure offset distance can be overcome, the lubricating oil that gear stirs smoothly is introduced to bearing,
Guarantee bearing in the lubrication needs of the bad working environments such as low speed, slope road.
The oil trap 4 is made of end to end side plate 4-1 and bottom plate 4-2, and side plate 4-1 has longitudinal inclination,
Bottom plate 4-2 has lateral inclination angle.This two angles are conducive to collect lubricating oil and lubricating oil are promoted smoothly to flow into oil duct.
Difference in height is equipped between the oil baffle 2 and perforation axle bearing inner ring and roller.This difference in height can store some profits
Lubricating oil, while can guarantee that vehicle lubricating oil liquid level at 30% upward slope road surface is dipped into bearing roller, meet bearing lubrication requirement.
It is to sum up told, the present invention will be lubricated according to drive axle internal lubrication oil flowing law by the ingehious design of structure
Oil introduces the severe perforation axle bearing of greasy property, and so that the bearing is can satisfy operating conditions lubrication needs, the bearings such as low speed, slope road can
It is guaranteed by property.

Specific embodiment
Technical solution of the present invention is discussed in detail below in conjunction with attached drawing:
As shown in Figures 1 to 5, a kind of perforation bearing housing of the drive axle jackshaft with lubricating function, by bearing block 1,
Oil baffle 2, oil duct 3,4 four part of oil trap are constituted.Bearing block 1 is equipped with through hole and 1 bottom of bearing block for installing bearing
For flaunching structure, through hole and the flaunching structure junction of bearing block 1 is arranged in oil baffle 2, and oil duct 3 is provided with bearing block 1 and passes through
In through-hole, 3 one end of oil duct connects oil baffle 2, and 3 other end of oil duct is connected to oil trap 4, and oil trap 4 is arranged in 1 flange of bearing block
Structural base.Oil trap 4 is made of end to end side plate 4-1 and bottom plate 4-2, and side plate 4-1 has longitudinal inclination b, bottom
Plate 4-2 has lateral inclination angle a.Oil baffle 2 and bearing inner race and roller have difference in height L.
The working principle of the invention:
The flow route of drive axle position lubricating oil are as follows: the lubricating oil that driven wheel of differential stirs → 4 → oil duct of oil trap 3 →
Bearing → 2 → axle housing of oil baffle.Due to having certain offset distance between driven wheel of differential and perforation axle bearing, the lubricating oil that it is stirred
It cannot be directly thrown on bearing in low speed, and the design of bearing block through the invention, structure offset distance can be overcome, gear is stirred
The lubricating oil risen is smoothly introduced to bearing, guarantees bearing in the lubrication needs of the bad working environments such as low speed, slope road.Oil trap simultaneously
4 are made of side plate 4-1 and bottom plate 4-2, and there is side plate 4-1 tilt angle b, bottom plate 4-2 to have tilt angle a, this two angles
Be conducive to collect lubricating oil and lubricating oil is promoted smoothly to flow into oil duct.And oil baffle 2 and bearing inner race and roller have difference in height
L, this difference in height can store some lubricating oil, while can guarantee that vehicle lubricating oil liquid level at 30% upward slope road surface is dipped into axis
Bearing roller meets bearing lubrication requirement.
The present invention successfully overcomes perforation axle bearing lubrication caused by structure offset distance between driven wheel of differential and perforation axis
Bad problem smoothly introduces the lubricating oil that gear stirs to bearing, guarantees bearing in the profit of the bad working environments such as low speed, slope road
Sliding demand.Present invention can ensure that vehicle penetrates through axle bearing at 30% upward slope road surface, lubrication is good, this index is conventional junction
Structure institute is inaccessiable.
