Description
Technical field:
The utility model relates to motorcycle, and is particularly a kind of simple in structure, the selector of the chain type motor-tricycle that is easy to handle.
Background technique:
The selector of existing chain type motor-tricycle, be in a selector housing, inwardly to be connected with output shaft and input shaft by output sprocket and input sprocket, on two line shafts, be respectively equipped with driving gear, between two driving gears, be provided with a cover variable transmission mechanism, on two line shafts, be respectively equipped with operating handle and guide into outside the housing.This drive mechanism, complex structure, transmission program is many, operates not easyly, and velocity ratio is unreasonable, gives to manipulate to make troubles, and is difficult to correctly reverse gear and variable block at a slow speed poor safety performance.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, pin manipulation, the selector of the chain type motor-tricycle that Safety performance is good.
Technical solution of the present utility model is finished as follows, it includes a selector casing, parallel output shaft and input shaft and their sprocket wheel of being equipped with in the casing, it is characterized in that: on the input shaft in casing both sides be fixedly connected with a gearwheel and a small gear respectively, one three wheel is installed in casing, endwisely slipping on the output shaft, a transmission shaft is installed in casing between input shaft and output shaft, on transmission shaft, be connected with one with the input pinion the transmission gearwheel, the transmission shaft middle part is equipped with driving pinion, three wheels are provided with large, medium and small three gears and a fork slot, three the United Nations General Assembly's gears are corresponding engageable or separate with the input gearwheel, three middle gears are corresponding with driving pinion engageable or separate, three small gears are corresponding with the transmission gearwheel engageable or separate, shift fork is installed in fork slot, the upper end of shift fork is installed on the case lid by declutch shift shaft, the declutch shift shaft outside is joined with the declutch shift shaft cunning in the case lid through hole steel ball is installed, is equipped with one by spring and locking cap in the through hole on the steel ball and regulates silk, correspondingly with steel ball on declutch shift shaft be provided with three gearshift grooves.
The utlity model has simple in structurely, pin is handled, and shift control is easy, the advantage that Safety performance is good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model; Fig. 2 is a shift fork structural representation of the present utility model; Fig. 3 is the structural representation of the utility model declutch shift shaft.
Embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, as shown in Figure 1, the utility model is parallelly in casing 1 to be separately installed with output shaft 4 and input shaft 10 by bearing 14, both sides are fixedly connected with a gearwheel 13 and a small gear 9 respectively in the input shaft upper box, in casing, endwisely slip on the output shaft be equipped with one three the wheel 12, a transmission shaft 2 also is installed in the casing between output shaft and input shaft, be connected with a transmission gearwheel 5 with the input pinion on the transmission shaft, the transmission shaft middle part is equipped with a driving pinion 11, three wheels are provided with large, medium and small three gears and a fork slot 3, three the United Nations General Assembly's gears are corresponding with input gearwheel 13 engageable or separate, three middle gears are corresponding with driving pinion engageable or separate, three small gears are corresponding with the transmission gearwheel engageable or separate, shift fork 16 is installed in fork slot, the upper end of shift fork is installed on the case lid 23 by declutch shift shaft 21, the declutch shift shaft outside is joined with the declutch shift shaft cunning in the case lid through hole steel ball 17 is installed, is equipped with one by spring 18 and locking cap 19 in the through hole above the steel ball and regulates silk 20, correspondingly with steel ball on declutch shift shaft be provided with three gearshift grooves 24.The declutch shift shaft outer end is connected on the pin, can drive declutch shift shaft by a pin during operation and shift fork keeps off soon, the operation that keeps off slowly and reverse gear, easy and simple to handle, in order to increase sealability of the present utility model, at input shaft, the two ends of transmission shaft and output shaft are respectively equipped with end cap 15, are provided with skylight cover 22 on case lid, and input sprocket 7 and output sprocket 6 are arranged on input shaft and output shaft.Be respectively equipped with oil sealing 8 on input shaft and the output shaft in one side end cap.
Working principle of the present utility model is, when stirring shift fork three the United Nations General Assembly's gears is meshed with gearwheel on the input shaft.At this moment, the gearwheel that the small gear on the input shaft drives on the transmission shaft rotates, and output sprocket drives rear axle beam with chain, reverses gear to travel.When needs travel at a slow speed, stir shift fork, make the engagement of three middle gears and driving pinion, the gearwheel on the transmission shaft is engaged on the input small gear at this moment, drives rear axle beam by output sprocket with chain, travels at a slow speed.When the needs fast running, stir shift fork three small gears are meshed with the transmission gearwheel, the gearwheel on the transmission shaft is engaged on the input small gear at this moment, drives rear axle beam by output sprocket with chain and carries out fast running.
