2, output speed wave range is little;
3, low cost of manufacture.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation of gearbox automatic gearshift of the present invention.
wherein: 1, three oil cylinders; 13, the first bulb; 2, push rod; 20, push rod cup; 21, push rod flange; 22, spherical inner chamber; 23, bolt; 3, driving lever; 30, the second bulb; 4, slide bar; 5, shift fork; 6, the first gear; 7, sliding sleeve; 8, output gear; 9, the second gear; 10, output shaft; 11, joint sleeve; 110, annular groove; 12, bounding means.
Embodiment
below in conjunction with drawings and Examples, the invention will be further described:
a kind of gearbox automatic gearshift as shown in Figure 1, comprise and there is a left side, in, three oil cylinders 1 of right three gears, being in transmission connection mutually with three oil cylinders 1 can the push rod 2 of movement in the horizontal direction, being in transmission connection mutually with push rod 2 can the slide bar 4 of movement in the horizontal direction, be connected to the shift fork 5 on slide bar 4, the sliding sleeve 7 be connected with fork 5, output gear 8, the output shaft 10 be meshed with output gear 8, first gear 6, second gear 9 and the bounding means 12 for limiting slide bar 4 sliding position, first gear 6, second gear 9 lays respectively at a left side for output gear 8, right both sides.Wherein:
push rod 2 comprises push rod cup 20, the push rod flange 21 be connected on push rod cup 20, and push rod cup 20, push rod flange 21 are connected by bearing pin 23, and forms spherical inner chamber 22 between; Three oil cylinders 1 comprise first bulb 13, first bulb 13 and are arranged in spherical inner chamber 22, form universal connecting structure, thus reduce the installation precision of three oil cylinders 1 and push rod 2.
push rod 2 there is driving lever 3 by pinned connection, driving lever 3 has second bulb 30; Slide bar 4 is connected with joint sleeve 11, joint sleeve 11 has annular groove 110, the second bulb 30 is fastened in annular groove 110, thus reduces the installation precision of driving lever 3 and joint sleeve 11.
