Abstract
The utility model provides a gear box for an electro-tricycle. A gear box body is internally provided with an input shaft and an output shaft which are connected with the gear box body and are arranged in a fundamentally parallel way, the input shaft is connected with the power motor of the electro-tricycle, and an input gear and a shaft gear are connected onto the input shaft, while the output shaft is connected with the main shaft of the electro-tricycle, and a double step sliding gear which is respectively meshed with the input gear and the shaft gear on the input shaft is connected onto the output shaft, furthermore, the double step sliding gear is also connected with the manipulation mechanism of the electro-tricycle through a shifting yoke and a shifting connector which are orderly connected with the double step sliding gear. Under the action of the gear box, the drive performance of the electro-tricycle can be effectively improved, the electro-tricycle can run at the normal speed when the road condition is good, and the forward driving can be effectively realized as the electro-tricycle is enabled to increase the power while decelerating when the road condition is bad.
Description
Technical field
The utility model relates to a kind of speed changer, particularly the electro-tricycle speed changer.It can make the electro-tricycle Reduced Speed Now and increase its power.
Background technique
Usually, electro-tricycle relies on intrinsic power and speed, can travel normally under the good situation of road conditions, still, run into road conditions bad the time, particularly in the rural area, the building site, the road major part is based on dirt road, road conditions are relatively poor, if run into rainy day again, road conditions can be worse.Under such road condition, it is not enough that the power of electro-tricycle can seem, the difficulty of travelling, or even can't travel is made troubles and bothered to the user.
Summary of the invention
The purpose of this utility model is to provide a kind of electro-tricycle speed changer, it can overcome the deficiency of prior art, can make electro-tricycle in Reduced Speed Now, can increase the power of electro-tricycle effectively, make them under any road conditions, all can travel and advance.
Its solution is, be provided with its connection in the gearbox casing and be input shaft and the output shaft that substantially parallel shape is arranged, input shaft is connected with the power motor of electro-tricycle, and on input shaft, be connected with input gear and shaftgear, and output shaft is connected with the main shaft of electro-tricycle, and be connected with respectively the double crosslinking sliding gear that is meshed with the input gear that is provided with and shaftgear on the input shaft on the output shaft, and this double crosslinking sliding gear is again by dialling wooden fork and gearshift link with the gearshift that it is connected successively, with the operating mechanism connection of electro-tricycle.
The utility model adopts technique scheme, and speed changer is a power source with the power motor of electro-tricycle still.Under the effect of speed changer, can improve the rideability of electro-tricycle effectively, can travel with normal speed when road conditions are good, when road conditions are bad, can make electro-tricycle in Reduced Speed Now, increase its power, still can travel effectively and advance.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Among Fig. 1 to Fig. 4, be fixedly connected with end cap 8,10 in the both sides of gearbox casing 1, form the casing of sealing.In gearbox casing 1, be provided with the input shaft 9 and the output shaft 12 that are connected and parallel layout respectively with end cap 8,10 bearings.Be connected with shaftgear 17 on input shaft 9, its number of teeth is 11, the input gear 16 of on this, fixedlying connected with its key in addition, and its number of teeth is 30.And the end that input shaft 9 is positioned at gearbox casing 1 outside is tightly connected with end cap 8 again through oil sealing 15, preventing the oil that leaks, and the input sprocket 2 of on this axle head, fixedlying connected with its key in addition.Input shaft 9 is connected (not drawing among the figure) by the input sprocket 2 that connects on it with the power motor output shaft chain-driven of electro-tricycle.And key is connected with double crosslinking sliding gear 14 on the output shaft 12, and its gearwheel number of teeth is 39, and the small gear number of teeth is 20, and the large and small gear of this double crosslinking sliding gear 14 respectively be connected input shaft 9 on shaftgear 17 and the input gear 16 be meshed.Double crosslinking sliding gear 14 is again by dialling wooden fork 7 with the gearshift of its socket connection, it is tightly connected by oil sealing 18 and end cap 8, and dial gearshift link 4 that wooden fork 7 is hinged by pin bolt 3 be connected with the operating handle of the operating mechanism of electro-tricycle (not drawing among the figure) with gearshift, and gearshift link 4 is hinged through pin bolt 5 with the gearshift fixed block 6 that is fixedly connected on above the gearbox casing 1, under the effect of electro-tricycle operating mechanism operating handle, dial wooden fork 7 by gearshift and force double crosslinking sliding gear 14 to move axially along output shaft 12.Key is fixedly connected with output sprocket 11 on the end outside output shaft 12 is positioned at gearbox casing 1, this end is tightly connected by oil sealing 13 and end cap 10 again, and output shaft 12 is connected (not drawing among the figure) by the output sprocket 11 that connects on it with the main shaft chain-driven of electro-tricycle.
This speed changer is installed on the power motor and the chassis between the main shaft of electro-tricycle.The shared original power motor of speed changer and the electro-tricycle source that is used as power.When the operating handle of handling electro-tricycle, force gearshift to dial wooden fork 7 actions, and stir double crosslinking sliding gear 14 along output shaft 12 axial slips, the input gear 16 that is connected on the small gear that makes double crosslinking sliding gear 14 and the input shaft 9 is meshed, driving output shaft 12 rotates, and rotate by the main shaft that chain-driven drives electro-tricycle, make electro-tricycle according to intrinsic travelling speed, under the good situation of road conditions, travel.When the operating handle of handling electro-tricycle, forcing gearshift group wooden fork 7 to stir double crosslinking sliding gear 14 moves along output shaft 12, the shaftgear 17 that is connected on the gearwheel that makes double crosslinking sliding gear 14 and the input shaft 9 is meshed, driving output shaft 12 rotates, and rotate by the main shaft that chain-driven drives electro-tricycle, make the electro-tricycle Reduced Speed Now and can increase its power, can under the bad situation of road conditions, travel in the same old way and advance.
