Described gearshift swing arm is socketed on the buffer shaft, gearshift swing arm and rotation buffer arm free-running fit.

Described pivot arm is connected with the engine gear axle by permanent seat, and the permanent seat spline is connected on the engine gear axle.

Connect in the described rotation buffer arm or and connect the gearshift swing arm, and flexibly connect with buffer shaft.

Described gearshift swing arm top is a convex.

Begin to learn motor bike driver's the needs and the appearance of reply abnormal condition for adaptation, also be connected with gear level on the described engine gear axle.

Described sensing element is the induction permanent magnets.

Described transmission component is made of pivot arm and pull bar, and an end of pivot arm is connected on the engine gear axle, and the other end of pivot arm is connected with pull bar, and pull bar is connected with rotation buffer arm on the buffer shaft.

The technique effect that the utility model can reach is:

1, the utility model adopts to cooperate with microcomputer control system Based Intelligent Control is carried out in the self shifter action of motor bike, and gearshift is timely, accurate, put in place, and is simple, convenient, comfortable.

2, the utility model smooth operation, dependable performance, consumption of fuel is little, and mechanical wear is few, has prolonged the service life of parts such as driving engine, piston, cylinder block.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment 1.

The specific embodiment:

The utility model will be further described below in conjunction with accompanying drawing:

As shown in Figure 1: this Motorcycle automatic shift control device is included in the engine gear axle 2 that is provided with on the engine body, be connected with gearshift axle Rocker arm 4 on the engine gear axle 2, gearshift axle Rocker arm 4 is provided with induction permanent magnets 5, and the position of corresponding induction permanent magnets 5 is provided with displacement pickup 6; Engine gear axle 2 is connected with an end of pivot arm 3, the other end of pivot arm 3 is connected with pull bar 8, pull bar 8 is connected with rotation buffer arm 11 on the buffer shaft 12, gearshift swing arm 10 is connected on the S. A. 12, be provided with recoil spring 9 between gearshift swing arm 10 and the rotation buffer arm 11, gearshift swing arm 10 tops are convex, and gearshift swing arm 10 contacts with cam 14 activities that are fixed on deceleration actuating motor 13 output shafts, and the position of corresponding cam 14 is provided with cam-position sensor 15; Cam-position sensor 15, gearshift axial translation sensor 6 all are connected with microcomputer control system 7 with deceleration actuating motor 13.Begin to learn the needs of driving motorcyclist and the appearance of tackling abnormal condition for adaptation, also be connected with gear level on the engine gear axle 2.

Workflow is roughly as follows: under microcomputer control system 7 cooperates, 13 rotations of deceleration actuating motor, drive cam 14 cws or left-hand revolution, stir gearshift swing arm 10, under the cooperation of rotation buffer arm 11, buffer shaft 12 and recoil spring 9,, drive the rotation of engine gear axle 2 fore-and-aft directions and upgrade or shift-down action by pull bar 8 driven rotary arms, 3 conter clockwises or cw swing certain angle.But in the process of gearshift such situation can appear: the phenomenon that driving engine shift gear and engaging gear contact mutually, gearshift can not be finished, in case this situation occurs, microcomputer control system 7 can drive deceleration actuating motor 13 again and repeat above action, finish until gearshift, the intact action that do not become to shift gears if repeatedly repeat, then very possible engine system breaks down.
