The driving engine of existing motor-tricycle and back axle tooth bag direct connection make back axle tooth Bao Wei be in the center of back axle, in motion, because the back axle discontinuity equalization can cause back axle to bend, have reduced the service life of semiaxis.
The utility model content
The purpose of the utility model just provides a kind of motor-tricycle change speed gear box of realizing three-step gear shift.
The purpose of the utility model is to realize that through such technical scheme a kind of motor-tricycle change speed gear box comprises selector device and speed-changing mechanism, and said speed-changing mechanism is three three-gear gear shifting mechanisms.
Wherein, said three three-gear gear shifting mechanisms comprise vertically and are set in parallel in input shaft in the mission case, output shaft and two, on input shaft, output shaft and two, are provided with and control low speed, middling speed and high-revolving gear respectively.
Further; Said input shaft is provided with input driving tooth A; Said input driving tooth B, high speed tooth, middling speed tooth and the low speed tooth of on two, being disposed with, said output shaft is provided with output three and connects tooth, and said input driving tooth A and input driving tooth B are in the constant-mesh state.
For the ease of the speed change of operation change-speed box, said steering unit comprises declutch shift shaft, and an end of declutch shift shaft is provided with shift fork, and said shift fork is stuck in output three and connects on the tooth, and the other end of said declutch shift shaft is connected with drag-line.
In order to make back axle tooth bag be installed in the center of back axle, the distance between said input shaft and the output shaft is 120mm.
For the ease of installing, the mounting plane of said casing is provided with the hold-down bolt hole, and the distance in said two hold-down bolt holes on the length installation direction is 180mm, and the distance in said two hold-down bolt holes on the width installation direction is 110.5 mm.
Owing to adopted technique scheme, the utlity model has structure design advantage ingenious, easy to assembly, adopt it not only can realize the three-step gear shift of change-speed box; Satisfy rate request; And when being installed on the back axle, can make back axle tooth bag be in the back axle center, back axle is stressed evenly; Can not bend, prolong semiaxis service life.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is an A-A cutaway view among Fig. 1;
Fig. 3 is a B-B cutaway view among Fig. 1;
Fig. 4 is the utility model installing condition figure.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: like Fig. 1,2,3, shown in 4, a kind of motor-tricycle change speed gear box comprises selector device and speed-changing mechanism, and said speed-changing mechanism is three three-gear gear shifting mechanisms.
Wherein, said three three-gear gear shifting mechanisms comprise vertically and are set in parallel in input shaft 2 in the mission case 1, output shaft 3 and two 4, on input shaft 2, output shaft 3 and two 4, are provided with and control low speed, middling speed and high-revolving gear respectively.
Further; Said input shaft 2 is provided with input driving tooth A5; Said input driving tooth B6, high speed tooth 7, middling speed tooth 8 and the low speed tooth 9 of on two 4, being disposed with; Said output shaft 3 is provided with output three and connects tooth 10, and said input driving tooth A5 and input driving tooth B6 are in the constant-mesh state.
In the utility model, change speed gear box is work like this:
Low speed: stir output three through shift fork and connect tooth, will export three and connect tooth and the engagement of low speed tooth;
Its power transfer path is such: input shaft-two-low speed of input driving tooth A-input driving tooth B-tooth-output three connects tooth-output shaft.In low speed, the moving velocity of motor-tricycle is fit to heavy duty.
Middling speed: stir output three through shift fork and connect tooth, will export three and connect tooth and the engagement of middling speed tooth;
Its power transfer path is such: input shaft-two-middling speed of input driving tooth A-input driving tooth B-tooth-output three connects tooth-output shaft.In middling speed, the moving velocity of motor-tricycle is suitable for underloading.
At a high speed: stir output three through shift fork and connect tooth, will export three and connect tooth and the engagement of high speed tooth;
Its power transfer path is such: input shaft-two-high speed of input driving tooth A-input driving tooth B-tooth-output three connects tooth-output shaft.In high speed, the moving velocity of motor-tricycle is suitable for zero load.
In the utility model, said steering unit comprises declutch shift shaft 11, and an end of declutch shift shaft 11 is provided with shift fork 12, and said shift fork 12 is stuck in output three and connects on the teeth 10, and the other end of said declutch shift shaft 11 is connected with drag-line 13.
Distance between said input shaft 2 and the output shaft 3 is 120mm; Driving engine 15 main shafts are connected with input shaft 2, and back axle tooth bag 16 is connected with output shaft 3, has the deviation of 120mm between them, so just make back axle tooth bag 16 be in the center of back axle, have overcome the problem of back axle unbalance stress, make that the semiaxis life-span is longer.
