Description
Technical field
The present invention relates to transmission device, in particular to a kind of epicyclic gearing applied to MPV sliding door.
Background technique
With the development of science and technology, the sliding door of MPV is realized by door handle Mechanical Driven to motor-driven transformation,
Although however motor driven sliding door the operation is stable, when passenger because sliding door motor driven speed it is partially slow, so using volume
Transmission mechanism small, that transmission ratio is big, high-efficient is driven to realize.
Summary of the invention
The purpose of the invention is to overcome the above problem, a kind of epicyclic gearing applied to MPV sliding door is provided.
In order to achieve the above objectives, the method that the present invention uses is: a kind of epicyclic gearing applied to MPV sliding door,
Including drive shaft, sun gear, planetary gear, gear ring and rack gear, the gear ring packet are successively arranged in drive shaft from inside to outside
Include inner ring and outer ring；The drive shaft provides power by motor, sends sun gear, planetary gear and sun gear to through drive shaft
Engagement, planetary gear is engaged with gear ring inner ring simultaneously, and the outer ring of the gear ring is directly engaged with rack, and rack gear and sliding door connect
It connects, the linear motion of rack gear drives the switch of sliding door.
As an improvement of the present invention, it is connected between drive shaft and sun gear with spline.
As an improvement of the present invention, the drive shaft is arranged on shaft stool, and passes through gear and shaft coupling
It is connected to the motor and connects.
The utility model has the advantages that
Epicyclic gearing provided by the invention applied to MPV sliding door small in size, weight using planetary gear construction
Gently, feature high-efficient, transmission ratio is big effectively improves transmission efficiency, and engagement state is stablized, and overall structure is simple, just
In processing and installation, keep sliding door more laborsaving convenient in use.
Detailed description of the invention
Fig. 1 is the principle of the present invention figure；
Fig. 2 is schematic structural view of the invention.
Each component in figure are as follows: 1 outer ring, 2 planetary gears, 3 inner rings, 4 sun gears, 5 drive shafts.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, and the present embodiment is with technical solution of the present invention
Premised under implemented, it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
Embodiment 1:
A kind of epicyclic gearing as depicted in figs. 1 and 2, the device include the drive shaft 5 being arranged on shaft stool, are driven
Sun gear 4, planetary gear 2, the inner ring 3 of gear ring, the outer ring 1 of gear ring and rack gear 6, power are successively arranged on moving axis 5 from inside to outside
It is provided by motor, sends sun gear 4 to through drive shaft 5, planetary gear 2 is engaged with sun gear 5, while being nibbled with the inner ring of gear ring 3
It closes, and the outer ring 1 of the gear ring is directly engaged with rack gear 6, through this route, power is transferred to rack-and-pinion, the linear motion of rack gear
Drive the switch of sliding door.
The working method of the epicyclic gearing and principle are further detailed below:
In the present embodiment on the transmission mechanism of epicyclic gearing installation Mr. Yu MPV sliding door, the outer ring 1 of gear ring and control
The rack gear 6 of sliding door Push And Release processed directly engages, and drive shaft 5 gets off the torque transfer of motor through shaft coupling, gear etc., works as drive
Moving axis 5 drives sun gear 4 to rotate, and torque is transferred to sun gear 4 from drive shaft 5, and sun gear 4 drives planetary gear 2 to rotate, planet
Gear 2 drives ring gear against rotation, and the rack gear 6 on sliding door is driven to move in a straight line.Compact structure dramatically saves lower part biography
Motivation conformational space, the characteristic that simple structure meets convenient for handling, replacement；Planetary gear high efficiency can also reduce energy
Input, sliding door using more laborsaving, convenient.
The technical means disclosed in the embodiments of the present invention is not limited to the technical means disclosed in the above technical means, and further includes
Technical solution consisting of any combination of the above technical features.It should be pointed out that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
