Abstract

The utility model discloses a drive speed changing mechanism of an electric tricycle, which comprises a back axle, an axle and a chainwheel. A changeover speed gear is installed at the side of the middle part of the back axle. A motor frame is arranged at one side of the changeover speed gear, and a drive axle is installed in the changeover speed gear to be parallel with the axle. A big declutch shift axle is arranged above the drive axle in parallel, and a small drive gear and a big drive gear are installed in the changeover speed gear are arranged on the drive axle in an axially sliding mode. A small driven gear and a big driven gear which are matched with the two drive gears to alternately drive are installed in the changeover speed gear on the axle. A big shifting fork is fixed to the big shifting fork in the changeover speed gear, and a small shifting fork is arranged on the wall of the changeover speed gear in a mode of corresponding to the big shifting fork. A draw rod handle is fixed to the external end of the small shifting fork and the inner end is clamped and connected to the big shifting fork. The chainwheel connected with the chainwheel of the motor by the chain is arranged at the outer side of the changeover speed gear on the drive axle. When the utility model is used to start and climb the slope, the utility model saves labor and the motor and the circuit can not be burned out. When the utility model runs normally on the flat ground, the power is enhanced.

Description

The electro-tricycle transmission shifting mechanism
Technical field
The utility model relates to electro-tricycle, particularly a kind of have starting and climb laborsaving, the electro-tricycle transmission shifting mechanism that has protection motor and circuit function simultaneously.
Background technology
Existing electro-tricycle transmission device, a side that is middle part on back axle is equipped with a motor, drive sprocket is installed on the motor output shaft, the corresponding drive sprocket of axletree in back axle place also is provided with a driving chain wheel, is connected with chain between above-mentioned two sprocket wheels, and itself does not have gearshift performance this transmission device, have only during driving with becoming the resistance handle and regulate the speed of a motor vehicle, this relatively takes electricity when just making battery-driven car starting and climbing, often burns out motor or circuit, simultaneously delelivered payload capability is restricted.
Summary of the invention
The purpose of this utility model provides a kind of starting and relatively power saving of climbing, not easy burn-out motor or circuit, electro-tricycle transmission shifting mechanism that delelivered payload capability is big.
The technical solution of the utility model is finished as follows, it includes back axle, axletree and sprocket wheel, it is characterized in that: a transmission gearbox is installed in side, back axle middle part, transmission gearbox one side is provided with the motor frame, the interior parallel transmission shaft that is equipped with of transmission gearbox with axletree, transmission shaft top is parallel to be equipped with big declutch shift shaft, in transmission gearbox, endwisely slip on the transmission shaft two transmission gears of size are installed, alternately little big two ring gears of transmission that match with two transmission gears are being installed in transmission gearbox on the axletree, in transmission gearbox, be fixed with a big shift fork of stirring two transmission gears on the big shift fork, a little shift fork is installed on the transmission tank wall of the big shift fork of correspondence, little shift fork outer end is fixed with the pull bar handle, the inner is connected on the big shift fork, and a sprocket wheel that is connected by chain with motor sprocket is installed in the outside of transmission gearbox on transmission shaft.The utility model is owing to be provided with the interchangeable transmission gear of two covers in transmission device, when starting and climbing, drive big ring gear with small transmission gear, make it laborsaving, can not burn out motor and circuit, when the cruising of level land, drive little ring gear, make it to improve power and hurry up energy-conservation with big transmission gear.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is that the partial cutaway of Fig. 1 is shown power.
Among the figure: 1, transmission gearbox; 2, motor frame; 3, big ring gear; 4, little ring gear; 5, small transmission gear; 6, sprocket wheel; 7, transmission shaft; 8, big declutch shift shaft; 9, big shift fork; 10, pull bar handle; 11, little shift fork; 12, big transmission gear; 13, axletree; 14, back axle.
The specific embodiment
The utility model is improvements over the prior art, mainly be that a side is fixedly connected with a transmission gearbox 1 by flange in the middle of back axle 14, one side of transmission gearbox is provided with motor frame 2, parallel with axletree 13 in the transmission gearbox transmission shaft 7 is installed, transmission shaft top is parallel to be equipped with big declutch shift shaft 8, in transmission gearbox, endwisely slip on the transmission shaft a big transmission gear 12 and a small transmission gear 5 are installed, two alternately ring gears of transmission that match with two transmission gears are being installed in transmission gearbox on the axletree, when its big ring gear 3 is meshed with small transmission gear 5, be used for starting and climbing; Little ring gear 4 is used for driving a vehicle at ordinary times when matching with big transmission gear.Being used alternatingly by the big shift fork 9 of little shift fork 11 drives of pull bar handle 10 manipulations of two sleeve gears finished, their annexation is, big shift fork is fixed on the centre of two power wheels in transmission shaft 7 tops in the transmission gearbox, the inner end of little shift fork fixes on big shift fork, little shift fork outer end is fixed with pull bar handle 10, and tween drive shaft is connected on the transmission tank wall.During use, as long as on motor frame 2, install motor, between the sprocket wheel 6 on the sprocket wheel of motor shaft outer end and the transmission shaft, be connected chain, and the outer end of pull bar handle connected pull bar towards operating console again, the clutch that can handle two cover transmission gears in the transmission gearbox replaces, and selects the needed position of different driving states.
