According to the forklift speed changer clutch gear assembly, the special buckle rings are arranged between the clutch gear assembly gear hub and the clutch gear sleeve to fix the meshing push block in a tensioning mode, the structural design is economical and practical, and gear engaging and gear shifting are convenient and flexible.
Description
Technical field
The utility model relates to a kind of forklift speed variator clutch tooth assembly, is applied to 3～5T level forklift speed variator assembly.
Background technique
Fork truck belongs to crane tool haulage vehicle, particularly 3～5T level fork truck is widely used especially, thoroughly change people's half the circumference of the sleeve where it joins the shoulder and chosen original labor style, because the fork truck motion speed is slow, the walking synchronizer gearshift of particularly bearing a heavy burden need to alleviate quick, steady, light, flexibly labor intensity of operating staff and strengthen the sense of security, and synchronizer is made reduce trouble durable in use simultaneously.The application of the clutch tooth assembly of new design makes its function reach predetermined target.
Summary of the invention
The utility model provides a kind of forklift speed variator clutch tooth assembly, adopts the special clasp bullet fixed engagement pushing block that rises between clutch tooth assembly tooth hub, the cover, and structural design is economical and practical, makes to hang the very light and flexible of shifting gears.
The utility model has adopted following technological scheme: a kind of forklift speed variator clutch tooth assembly, it comprises clutch tooth cover, clutch tooth hub, engagement pushing block and special clasp, the clutch tooth cover is enclosed within the outer surface of clutch tooth hub, special clasp is positioned at place, the large footpath of clutch tooth hub both ends of the surface spoke groove, and special clasp will mesh pushing block and be fixed on the clutch tooth hub; Described clutch tooth cover cylindrical is provided with fork slot and is used for dialling gear, the both sides, footpath are provided with oil storage tank at the bottom of fork slot, it is corresponding with the convex surface of engagement pushing block to be provided with undercut slots in the described clutch tooth cover endoporus, also establishes some standard involute spliness in endoporus, and the spline two ends are provided with herringbone angle and anti-off cone.
Described clutch tooth cover endoporus involute splines herringbone angle angle is 106 °, and the spline two ends are provided with 6 ° of anti-off cones; 120 ° of described clutch tooth hub external splines circumference are provided with 3 engagement pushing block grooves, and special clasp will mesh the pushing block bullet and rise to be fixed on and mesh on the pushing block groove; The making material of described special clasp is 65Mn, and the making material of engagement pushing block is the 35# cold drawn steel, and the clutch tooth cover is alloyed steel with the making material of clutch tooth hub.
The utlity model has following beneficial effect: the clutch tooth assembly adopts the special clasp bullet fixed engagement pushing block that rises, when the clutch tooth cover axially moves, synchronizing ring and synchronizing cone two parts are under responsive to axial force, the conical surface produces frictional force, when two gear speeds equate, clutch tooth cover internal spline enters smoothly the synchronizing cone external splines and finishes gearshift; Clutch tooth cover herringbone angle is improved and the anti-off cone setting, makes the gearshift light and fast safe and reliable, and obviously shorten lock in time, lock in time mean value＜0.61 second; The both sides, footpath are provided with oil storage tank at the bottom of the clutch tooth cover fork slot, have improved lubricating condition between shift fork and fork slot surface of contact, have improved parts usability and working life, and clutch tooth assembly design technology is strong, is conducive to cost efficiency, suitable batch production.
