Abstract

The utility model discloses an arrangement structure of a gear change system of a motorcycle engine. The arrangement structure has the key points that: a right crankcase body of the motorcycle engine is provided with a gear shift motor; two engaged dual gear I and dual gear II are arranged between the right crankcase body and a right crankcase cover side by side; a fan-shaped gear is arranged on a variable-speed shaft and is engaged with the dual gear II; an output shaft of the gear shift motor is used for driving the dual gear I to rotate; further, the fan-shaped gear is driven through the dual gear II to rotate; and finally, the variable-speed shaft rotates. The arrangement structure has a simple and compact structure and is rational in arrangement; the original structure of the normal motorcycle engine is effectively utilized; and thus, the motorcycle engine has an automatic gear shift function.

Description

A kind of motor cycle engine variable-speed gear system arrangement structure

Technical field

The utility model relates to the layout structure that a kind of motor cycle engine utilizes gear change.

Background technology

Growing along with motorcycle technology, the user also has higher requirement to motor bike itself, hopes that motor bike is should riding manipulation convenient, and energy-conserving and environment-protective are fuel-efficient again.Common in the market motor bike (beam bending bicycle, knight's car) is because must artificial gearshift when riding; Making needs artificial subjective judgement gear shift on the riding manipulation property constantly; And need trick to cooperate and have cooresponding harmony ability smooth shifting, for most of women or inexperienced navigating mate, certain difficulty is arranged; Though and the scooter that occurs to this problem has adopted stepless speed variator system (CVT), do not need artificial gearshift when riding, have also that driving efficiency is low, consumption rate of fired oil is high, shortcomings such as cost of price height; So the customer group that these two kinds of products itself are directed against has certain limitation.For thoroughly addressing this problem, can consider on common motor cycle engine, to increase the mechanism of autoshift, make the function of the existing autoshift of this motor bike, possess low oil consumption simultaneously, the product advantage of low price.But because the structure of driving engine itself is compact completely, do not have unnecessary space mounting self-clanging gear-shift on the common motor cycle engine.

The utility model content

The purpose of the utility model provides a kind of compact motor cycle engine variable-speed gear system arrangement structure of arranging.

To achieve these goals; Adopt following technical scheme: a kind of motor cycle engine variable-speed gear system arrangement structure is characterized in that: a kind of motor cycle engine variable-speed gear system arrangement structure is characterized in that: the gear shifting motor that is provided with on the right crankshaft box of motorcycle engine; Be arranged in juxtaposition two dual gear I that are meshed and dual gear II between right crankcase and the right crankcase cover; Quadrant gear is installed on the variable shaft, quadrant gear and the engagement of dual gear II, the output shaft of shift motor drives the dual gear I and rotates; And then the transmission through the dual gear II drives quadrant gear and rotates, and finally makes the variable shaft rotation.

The utility model is simple in structure, compact, and connection and reasonable arrangement has effectively been utilized the original structure of common motor cycle engine, makes motor cycle engine possess the self shifter function.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Fig. 1 is the front view of the utility model;

Fig. 2 is the birds-eye view of Fig. 1.

Among the figure, part 1 is a right crankcase, and part 2 is a variable shaft, and part 3 is a gear shifting motor, and part 4 is a quadrant gear, and part 5 is the dual gear II, and part 6 is the dual gear I.

The specific embodiment

As depicted in figs. 1 and 2, on general motor cycle engine, gear shifting motor 3 is installed in the front lower place of right crankcase 1; Mounting arrangements quadrant gear 4 on variable shaft 2; Suitably increase the locus of right crankcase 1 front lower place; Under the situation of not interfering other parts; Make dual gear II 5 and dual gear I 6 engagement layouts side by side, and the gear mesh of dual gear I 6 and gear shifting motor 3, dual gear II 5 and quadrant gear 4 gears mesh.Through the rational deployment transmission gear on right crankcase 1, the propulsive effort of gear shifting motor 3 is delivered on the variable shaft 2, realize the autoshift function.

Claims

1. motor cycle engine variable-speed gear system arrangement structure; It is characterized in that: the gear shifting motor that is provided with on the right crankshaft box of motorcycle engine; Be arranged in juxtaposition two dual gear I that are meshed and dual gear II between right crankcase and the right crankcase cover; Quadrant gear is installed on the variable shaft, quadrant gear and the engagement of dual gear II, the output shaft of shift motor drives the dual gear I and rotates; And then the transmission through the dual gear II drives quadrant gear and rotates, and finally makes the variable shaft rotation.
