The utility model provides an energy-conserving derailleur of new forms of energy can solve the problem that points out among the background art.
A new energy-saving transmission comprises a shell, wherein the shell is provided with a planetary gear transmission, a two-way clutch and a differential mechanism, the power output end of the planetary gear transmission is in transmission connection with the input end of the two-way clutch, the output end of the two-way clutch is in transmission connection with the input end of the differential mechanism, the two-way clutch comprises a rotating shaft, a large gear and an overrunning clutch are fixedly arranged on the rotating shaft, a small gear is sleeved on the overrunning clutch, the large gear is in gear connection with the power output gear of the planetary gear transmission, and the small gear is in gear connection with the input gear of the differential mechanism;
preferably, one side of the pinion is fixedly provided with a gear ring and a spiral key, the spiral key is sleeved with a spiral sleeve, and one side of the spiral sleeve is provided with spiral sleeve teeth matched with the gear ring.
Preferably, a damping spring is arranged between the gear ring and the spiral sleeve.
The utility model provides an energy-conserving derailleur of new forms of energy combines planetary gear derailleur, two-way clutch and differential mechanism, can make the vehicle slow down or the parking in-process, and driving motor no longer rotates passively, has reduced the driving resistance, reduces the loss of the energy, in addition, still protects driving motor, prolongs its life.

Detailed Description
In the following, an embodiment of the present invention will be described in detail with reference to the drawings, but it should be understood that the scope of the present invention is not limited by the embodiment.
As shown in fig. 1-8, an energy-saving transmission using new energy provided by an embodiment of the present invention includes a housing 1, the housing 1 is provided with a planetary gear transmission 2, a two-way clutch 3 and a differential 4, two ends of the planetary gear transmission 2, the two-way clutch 3 and the differential 4 are rotatably supported and fixed in the housing 1 through bearings, a power input end of the planetary gear transmission 2 (the planetary gear transmission may be a continuously variable transmission) is in transmission connection with a driving motor, a power output end of the planetary gear transmission 2 is in transmission connection with an input end of the two-way clutch 3, an output end of the two-way clutch 3 is in transmission connection with an input end of the differential 4, an output end of the differential 4 is in transmission connection with a wheel axle to drive the wheel to rotate, the two-way clutch 3 includes a rotating shaft 31, a large gear 32 and an overrunning clutch 33 are fixedly, a small gear 34 is sleeved on the overrunning clutch 33, the large gear 32 is in gear connection with the power output gear 21 of the planetary gear transmission 2, and the small gear 34 is in gear connection with the input gear 41 of the differential 4; when the vehicle decelerates or stops, the rotating speed of the driving motor gradually decreases, the speed of the rotating shaft 31 also slowly decreases immediately, when the rotating speed of the wheel axle (namely the rotating speed of the pinion 34) is higher than the rotating speed of the rotating shaft 31, the overrunning clutch plays a role, at this time, the rotating shaft 31 stops rotating, only the pinion 34 continues rotating, and as the rotating shaft 31 stops rotating, the planetary gear transmission 2 does not work any more, so that the driving motor is not driven to rotate passively, therefore, the driving motor stops rotating in the vehicle decelerating or stopping process, thereby reducing the driving resistance, reducing the energy consumption, protecting the driving motor and prolonging the service life.
In order to realize the reversing function of the electric vehicle, a gear ring 35 and a spiral key 36 are fixedly arranged on one side of the pinion 34, a spiral sleeve 37 is sleeved on the spiral key 36, the spiral key 36 rotates forwards and backwards, the spiral sleeve 37 can reciprocate along the length direction of the spiral key 36, spiral sleeve teeth 38 matched with the gear ring 35 are arranged on one side of the spiral sleeve 37, when the vehicle reverses, the rotating shaft 31 and the spiral key 36 reverse, the spiral key 36 reverses, the spiral sleeve 37 moves towards one side of the gear ring 35, the gear ring 35 and the spiral sleeve teeth 38 rotate in a tooth combining manner, the spiral sleeve 37 can drive the pinion 34 fixed with the gear ring 35 to reverse, and the pinion 34 reverses to finally enable the vehicle to retreat, so that the reversing function is realized.
In order to avoid the gear rattling phenomenon, a damping spring 39 is arranged between the gear ring 35 and the screw sleeve 37.
The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the embodiments, and any changes that can be considered by those skilled in the art shall fall within the protection scope of the present invention.
