Abstract
The utility model discloses a speed changing device of an engine of a motorcycle. The speed changing device is characterized in that a motor is fixedly arranged in a mounting hole in a right crankcase, an output shaft of the motor is connected with dual gears on an intermediate shaft, and two ends of the intermediate shaft are respectively supported on crankcases at corresponding ends; the dual gears are simultaneously connected with a gear wheel, the gear wheel sleeves the right end of a transmission shaft, the middle of the transmission shaft is supported on a left crankcase, and a pinion at the left end of the transmission shaft is meshed with a sector gear; the sector gear sleeves the left end of a speed changing shaft via a spline, and corresponding positions of the speed changing shaft are respectively supported on the crankcases at corresponding ends. The speed changing device has the advantages that power of the motor (3) is transmitted onto the speed changing shaft (9) via the dual gears (5), the gear wheel (6), the pinion (8) and the sector gear (10), a gear shifting speed changing effect can be realized for the engine by the aid of different speeds of the motor (3), and accordingly the speed changing device can be operated easily and conveniently as compared with the traditional manual gear shifting mode of an engine of a motorcycle and is suitable for wide popularization and application.
Description
Technical field
The utility model belongs to motor cycle engine field, specifically, relates in particular to a kind of transmission system of motor cycle engine.
Background technology
Growing along with motorcycle technology, user also has higher requirement to motor bike itself, usually wishes that motor bike is should riding manipulation convenient, and energy-conserving and environment-protective are fuel-efficient again.Common motor bike (beam bending bicycle, knight's car) must artificial gearshift owing to riding in the market, making needs artificial subjective judgement gear shift constantly on riding manipulation, and need trick to coordinate and there is suitable harmony ability smooth shifting, for most of women or inexperienced navigating mate, have certain difficulty.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of motorcycle engine speed transmission device of control comfort.
The technical solution of the utility model is as follows: a kind of motorcycle engine speed transmission device, comprise left crankcase (1) and right crankcase (2), after these two casing mould assembling, be bolted to connection, it is characterized in that: in the mounting hole on described right crankcase (2), be installed with a motor (3), the output shaft of this motor is castellated shaft, and the output shaft of motor (3) is connected with the dual gear (5) on tween drive shaft (4), and the two ends of this tween drive shaft are supported on respectively on the crankcase of corresponding end; Described dual gear (5) is connected with big gear wheel (6) simultaneously, this big gear wheel is sleeved on transmission shaft (7) right-hand member, it is upper that this transmission shaft middle part is supported on described left crankcase (1), and the miniature gears (8) of transmission shaft (7) left end and quadrant gear (10) engagement; Described quadrant gear (10) is positioned at outside left crankcase (1), this quadrant gear is the left part in variable shaft (9) by spline package, the corresponding position of this variable shaft is supported on respectively on the left and right crankcases (1,2) of corresponding end, and the right-hand member of variable shaft (9) reaches outside right crankcase (2).
Adopt above transmission system, the power of described motor (3) is delivered on variable shaft (9) by dual gear (5), big gear wheel (6), miniature gears (8) and quadrant gear (10), and the difference by motor (3) rotating speed realizes the shifted of driving engine, so just simple to operation than the manual shfit mode of traditional motor cycle engine, be suitable for extensively promoting the use.
As preferably, described miniature gears (8) be axle toothing with transmission shaft (7), outside miniature gears (8) and quadrant gear (10), is covered with a left front cover, and this left front cover is fixedly connected with described left crankcase (1) by screw; The left end of described variable shaft (9) is milled with flat side, and this flat side passes the via hole on left front cover, and an angular transducer is installed in this via hole.
Adopt above structure, described miniature gears (8) is preferably axle toothing with transmission shaft (7), facilitates like this and manufactures and assembling.The rotational angle that is provided for detecting variable shaft (9) of described angular transducer, thus the mode of operation of this transmission system accurately controlled.
Beneficial effect: the power of motor described in the utility model (3) is delivered on variable shaft (9) by dual gear (5), big gear wheel (6), miniature gears (8) and quadrant gear (10), and the difference by motor (3) rotating speed realizes the shifted of driving engine, so just simple to operation than the manual shfit mode of traditional motor cycle engine, be suitable for extensively promoting the use.
