Embodiment
Referring to Fig. 1, gear shift action of the present utility model is moved by hydraulic driving shift fork 8 and is realized.Hydraulic system comprises valve body 1, oil cylinder 2,15 and piston 3,14.All on valve body 1, valve body 1 is fixed on the case of transmission for oil cylinder 2,15 and piston 3,14.At a shift fork 8, there are 3,14 and two oil cylinders 2,15 of two pistons to match with it. A piston 3,14 is respectively established at the two ends, the left and right sides of piston rod 13, and is movable in oil cylinder 2,15 separately.Two- piston 3,14 relative gap locations are connecting connecting plate 4, and these connecting plate 4 upper/lower terminals are respectively established U-shaped draw-in groove 16,17, see Fig. 2, and upper end draw-in groove 16 is fixedlyed connected with piston rod 13, and lower end draw-in groove 17 is connected with U-shaped draw-in groove 18 on the set square triangle 5.Upper end draw-in groove 16 with need guarantee that piston rod moves being connected of piston rod 13 and can drive connecting plate 4 and follow mobile getting final product.Because connecting plate 4 all is the U-shaped draw-in groove with set square triangle 5, therefore can connecting plate 4 staggering with set square triangle 5 and insert mutually be connected.The shape of set square triangle 5 is roughly as triangle, is connected with shift fork axle sleeve 7 with respect to the opposite side of draw-in groove 18.Be fixed with declutch shift shaft 6 on the housing of speed changer, shift fork axle sleeve 7 is placed on the declutch shift shaft 6, and sliding bearing 19 is respectively established at the two ends in the shift fork axle sleeve 7, cooperates with declutch shift shaft 6, and shift fork axle sleeve 7 declutch shift shaft 6 relatively moves axially.See Fig. 4, on a side of shift fork axle sleeve 7, be provided with positioning strip 11, have V-shaped groove 14 on the positioning strip 11, a locating stud 9 and V-shaped groove 14 corresponding settings that is fixed on the case of transmission arranged.Spring and ball are equipped with in the end of this locating stud 9, form Elastic Contact with V-shaped groove 14.When locating stud 9 was in V-shaped groove 14, speed changer was in neutral position, and this structure can be guaranteed accurate neutral position, prevents misoperation.Connect shift fork 8 on the shift fork axle sleeve 7, connecting plate 4, set square triangle 5, shift fork axle sleeve 7, positioning strip 11, shift fork 8 all are that precision welding is connected together.Tooth cover 12 is housed on the shift fork 8, in the middle of the centre and the both sides of tooth cover 12 and shift fork 8 link positions all are provided with moulding 10, comprise one pad and about two side pads, to reduce the vibration noise of gearshift procedure.
