Abstract
The invention discloses a kind of light-duty intermediate connecting forks of integrated bearing inner race, it mainly include intermediate support, intermediate connecting fork, locking nut, middle spline shaft, intermediate support bearing, intermediate support bearing is integrated in the outer circle of the intermediate connecting fork, intermediate support bearing is mounted on intermediate support, intermediate support and intermediate connecting fork is set to be assembled into an assembly, the intermediate connecting fork of integrated intermediate support is mounted on middle spline shaft, and locking nut locks middle spline shaft and realizes positioning.Intermediate support is integrated into intermediate connecting fork by the present invention, and bearing inner race is processed into alley with intermediate connecting fork outer round surface and is replaced, number of parts is reduced, to reduce the accumulated error after assembly, drive shaft cartridge, which is matched, reduces to two by three components, improves the assembly efficiency of driving-shaft assembly；Middle spline shaft length is reduced, middle spline shaft material is saved, reduces driving-shaft assembly weight, reduces transmission shaft rotary inertia, improves transmission shaft performance, reduces oil consumption when starting.
Description
Technical field
The present invention relates to the fields of truck drive shaft, and in particular to a kind of light-duty intermediate connecting fork of integrated bearing inner race.
Background technique
Existing driving-shaft assembly assembling structure is as follows: intermediate support is provided with the bearing with bearing Internal and external cycle, bearing band
Bracket is installed along on middle spline shaft, is compressed on bearing to middle spline shaft with intermediate connecting fork, then locked with locking nut
Consolidation shows bearing positioning.
Such structure has the following deficiencies: that middle spline shaft length is too long, and the material of consumption is more；Driving-shaft assembly weight
Heavier, the rotary inertia of driving-shaft assembly is big；Each element precision requires height, and it is big that there are accumulated errors after assembly；Driving-shaft assembly
Assembling link is more, and time-consuming for assembly.
Summary of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and provide a kind of integrated bearing inner race it is light-duty in
Between connecting fork.
The object of the present invention is achieved by the following technical solutions: the light-duty intermediate connection of this integrated bearing inner race
Fork mainly includes intermediate support, intermediate connecting fork, locking nut, middle spline shaft, intermediate support bearing, the intermediate connection
Intermediate support bearing is integrated in the outer circle of fork, intermediate support bearing is mounted on intermediate support, connects intermediate support and centre
It connects fork and is assembled into an assembly, the intermediate connecting fork of integrated intermediate support is mounted on middle spline shaft, in locking nut locking
Between splined shaft realize positioning.
Further, the alley as bearing inner race is provided in the outer circle of the intermediate connecting fork.
The invention has the benefit that
1, ball outlet channel is directly processed in intermediate connecting fork outer circle as bearing inner race, is reduced number of parts, is simplified structure；
2, bearing is not installed on middle spline shaft, shortens the length of middle spline shaft, reduce supplies consumption；
3, the rotary inertia of driving-shaft assembly is reduced, oil consumption when starting is reduced；
4, reduce Assembly part, to reduce the accumulated error after assembly；
5, drive shaft cartridge timing original need to fill and only need to fill two components after three components change assembly can be completed, and improve transmission
The assembly efficiency of axle assembly.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Description of symbols: intermediate support 1, intermediate connecting fork 2, locking nut 3, middle spline shaft 4, intermediate support bearing
5。
Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
Embodiment: as shown in the picture, the light-duty intermediate connecting fork of this integrated bearing inner race, mainly include intermediate support 1,
Intermediate connecting fork 2, locking nut 3, middle spline shaft 4, intermediate support bearing 5 are integrated in the outer circle of the intermediate connecting fork 2
Intermediate support bearing 5, intermediate support bearing 5 are mounted on intermediate support 1, and intermediate support 1 and intermediate connecting fork 2 is made to be assembled into one
A assembly reduces Assembly part quantity, to reduce the accumulated error after assembly, while need to fill three with middle script in drive shaft cartridge
A component need to only fill two components now can be completed assembly, improve the assembly efficiency of driving-shaft assembly；Integrated intermediate support 1
Intermediate connecting fork 2 be mounted on middle spline shaft 4, middle spline shaft 4 can cancel the bearing guard of axle bearing mount portion position, reduce
Middle spline shaft 4 processes bearing guard high-precision requirement, while can shorten the length of middle spline shaft 4；Locking nut 3 is locked
Middle spline shaft 4 realizes positioning.
It is provided with the alley as bearing inner race in 2 outer circle of intermediate connecting fork, can reach and reduce by a bearing inner race
Purpose of design.
Intermediate support is integrated into intermediate connecting fork by the present invention, and the intermediate connecting fork outer round surface of bearing inner race is added
Work alley replaces, it is possible to reduce number of parts reduces middle spline shaft length, saves middle spline shaft material, reduces transmission shaft
Assembly weight reduces transmission shaft rotary inertia, improves transmission shaft performance, reduces oil consumption when starting.Reduce Assembly part, from
And reduce the accumulated error after assembly.Drive shaft cartridge timing original need to fill and only need to fill two components after three components change and just complete to fill
Match, improves the assembly efficiency of driving-shaft assembly.The present invention practical application in light-duty transmission shaft assembly product.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
