Description

A kind of planetary reduction gear for automobile tail gate strut
Technical field
The present invention relates to a kind of planetary reduction gear for automobile tail gate strut, belong to technical field of automobile parts.
Background technology
With economic development, science and technology improves constantly.The vehicles are constantly updating, and automobile becomes for people's traffic Instrument, but with the development of science and technology, people to automobile requirement more and more higher.Tail-gate such as partial automobile is automatically turned on, closed Close.Automobile tail gate is opened, closes in link and can't do without electronic strut, and electronic strut mainly passes through deceleration device by electric rotating machine Realized using screw mandrel.Because tail-gate space is limited, existing decelerating through motor structure uses planetary reduction gear more, and planetary reduction box is by sky Between, speed reducing ratio influence, module very little, machining accuracy is difficult to reach, and easily causes gear abnormal sound.
The content of the invention
The invention aims to solve the above problems, there is provided a kind of simple in construction, compact to design is used for automobile The planetary reduction gear of tail door supporting rod.
The present invention adopts the following technical scheme that：A kind of planetary reduction gear for automobile tail gate strut, including base, external tooth Circle, primary planet reducing gear and two-stage planetary reduction mechanism, the two-stage planetary reduction mechanism are arranged on primary planet deceleration The surface of mechanism, the external toothing are arranged on the outside of primary planet reducing gear and two-stage planetary reduction mechanism；
The primary planet reducing gear includes one-level sun gear, and several one-level rows are provided with around the one-level sun gear Star-wheel, primary planet carrier is provided with the primary planet wheel, and the primary planet wheel is intermeshed with external toothing；
The two-stage planetary reduction mechanism includes secondary solar gear, and several two level rows are provided with around the secondary solar gear Star-wheel, secondary planet frame is provided with the secondary planet wheel, and the secondary planet wheel is intermeshed with external toothing；
The one-level sun gear is connected with motor output end, and the secondary solar gear is connected with primary planet carrier, the two level row Carrier is connected with output shaft.
Further, it is provided with helical teeth on the inside of the external toothing.
Further, the bottom of the external toothing is connected by nut with base.
Further, the upper end of the two-stage planetary reduction mechanism is provided with rolling bearing.
The present invention is simple in construction, compact to design, and the outside of external toothing can replace shell to use, and reduce on decelerator Parts, reduce the difficulty of processing, the noise during use can be reduced on the inside of external toothing using helical teeth, it is ensured that electronic support The stable performance of bar, ensure the stability of automobile power back door.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the schematic diagram of the external toothing of the present invention.
Reference：Base 1, external toothing 2, one-level sun gear 3, primary planet wheel 4, primary planet carrier 5, secondary solar gear 6th, secondary planet wheel 7, secondary planet frame 8, output shaft 9, rolling bearing 10.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Figure 1-Figure 2, a kind of planetary reduction gear for automobile tail gate strut, including base 1, external toothing 2, one-level Planetary gear speed reducing mechanism and two-stage planetary reduction mechanism, two-stage planetary reduction mechanism be arranged on primary planet reducing gear just on Side, external toothing 2 are arranged on the outside of primary planet reducing gear and two-stage planetary reduction mechanism；Primary planet reducing gear includes One-level sun gear 3, several primary planet wheels 4 are provided with around one-level sun gear 3, one-level is provided with primary planet wheel 4 Planet carrier 5, primary planet wheel 4 are intermeshed with external toothing 2；Two-stage planetary reduction mechanism includes secondary solar gear 6, the two level sun Be provided with several secondary planet wheels 7 around wheel 6, be provided with secondary planet frame 8 on secondary planet wheel 7, secondary planet wheel 7 with External toothing 2 is intermeshed；One-level sun gear 3 is connected with motor output end, and secondary solar gear 6 is connected with primary planet carrier 5, two level Planet carrier 8 is connected with output shaft, and the upper end of two-stage planetary reduction mechanism is provided with rolling bearing 10, and the inner side of external toothing 2 is provided with Helical teeth, the bottom of external toothing 2 are connected by nut with base 1.
External toothing 2 is integrally formed using powder metallurgy die casting, it is possible to increase the precision of inner side helical teeth.
Operation principle：The output end connection one-level sun gear 3 of motor, motor driven one-level sun gear 3 operates, the one-level sun Wheel 3 drives primary planet wheel 4, and primary planet wheel 4 completes primary speed-down, secondary solar gear 6 and primary planet carrier 5 with external toothing 2 It is integrally formed, therefore secondary solar gear 6 can operate with primary planet carrier 5, and then drive secondary planet wheel 7 to operate, two level row Star-wheel 7 completes double reduction with external toothing 2.
