Description
Technical field
The utility model is related to a kind of transfer case of automobile gearshift vibration and noise reducing devices, belong to transfer case of automobile shift machine
Structure technical field.
Background technology
Transfer case of automobile gearshift is mainly used to control transfer gear, and the function of gearshift is moved what speed changer exported
Power is assigned to each drive axle.And gearshift shell is being changed as the key components and parts for supporting and protecting enclosure interior gear
It keeps off in engineering, shell can be easy to cause gearshift shell cracking or damage by a variety of load such as shock and vibration.Traditional
Transfer gear gearshift internal gear driving member is not designed with vibration absorber, easily leads to shell structure failure, influences automobile
Safety traffic.
Utility model content
The technical problems to be solved in the utility model is：A kind of transfer case of automobile gearshift vibration and noise reducing device is provided,
It can not only realize the vibration damping of gearshift inner drive shafts, moreover it is possible to the noise reduction for realizing gear pair transmission process, to reach shift
The effect of mechanism vibration and noise reducing, with overcome the deficiencies in the prior art.
The technical solution of the utility model：A kind of transfer case of automobile gearshift vibration and noise reducing device, including be arranged in same
Gear wheel on a piece transmission shaft and pinion gear are socketed with spring retaining sleeve on the transmission shaft between the gear wheel and pinion gear
Pipe, spring retaining sleeve pipe is with outer ring, inner ring and a closed end, outer ring and inner ring in the other end shape opposite with closed end
At not closing opening, the shaft core position of closed end be provided with for pinion gear meshed gears hole, in outer ring and inner ring
Between be equipped with torsional spring, against on outer ring, the other end is resisted against on the fixture block being connected on the inside of gear wheel one end.
The inner ring is complete continuous sealing ring, and outer ring is the arc bulk to match with inner ring, and torsional spring wherein one end is supported
It leans against in arc bulk.
Due to using the technology described above, the utility model relies on the both ends fixed function of torsional spring, reduces gear drive
The impact and vibration of process, enhance the structural behaviour of transfer gear gearshift, weaken gear engagement impact power, improve machine
The service life of structure.The utility model is simple in structure, easy to assembly, of low cost, and using effect is ideal.

Specific implementation mode
It is new to this practicality below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Type is described in further detail.
Referring to figs. 1 to Fig. 4, a kind of transfer case of automobile gearshift vibration and noise reducing device of the present embodiment, including be arranged in same
It is solid to be socketed with spring on the transmission shaft 2 between gear wheel 6 and pinion gear 1 for gear wheel 6 on a piece transmission shaft 2 and pinion gear 1
Determine casing 3, spring retaining sleeve pipe 3 has outer ring 9, inner ring 8 and a closed end, and outer ring 9 and inner ring 8 are opposite with closed end
The other end formation do not close opening, outer ring 9 and inner ring 8 are connect with closed end, closed end shaft core position setting
Be useful for 1 meshed gears hole 7 of pinion gear, torsional spring 4 is installed between outer ring 9 and inner ring 8,4 one end of torsional spring is against outer ring 9
On, the other end is resisted against on the fixture block 5 being connected on 6 inside of gear wheel, and the above structure is the core component of the present apparatus, work
Principle is：In use, transfer case of automobile gearshift is driven by motor, and motor shaft drives high-speed gear rotation, passes through
Gear engaged transmission, realizes the output of Motor torque, can buffer gear cold biography by the fixed function at 4 both ends of torsional spring in the present apparatus
Impact force during dynamic and vibration force, and then the power being transmitted on transfer gear shell can be reduced, realize the purpose of vibration and noise reducing.
The inner ring 8 is complete continuous sealing ring, and outer ring 9 is the arc bulk to match with inner ring 8, torsional spring 4 wherein one
End is resisted against in arc bulk, while taking into account using effect, can also reduce certain material cost.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the scope of protection of the utility model.
