ACTUATOR OF EIGHT-LINK GEAR FOR LOADER-DIGGER LOADING SIDE Russian patent published in 2015 - IPC E02F3/34 

FIELD: transport.

SUBSTANCE: claimed actuator consists of the front frame, moving jig, rotary bucket hydraulic cylinder, rotary bucket lever, rotary bucket tensioner, moving bucket drawbar and moving jig and bucket lever. said frame is articulated with jig one end at point A, moving jig drawbar one end at point C and moving jig hydraulic cylinder at point E. Moving jig opposite end is articulated with the bucket at point B. Moving jig drawbar opposite end is articulated with moving jig one end at point D. Moving jig hydraulic cylinder opposite end is articulated at jig centre point F. Moving jig lever centre is articulated with moving jig at point G. Moving jig lever opposite end is articulated with rotary bucket hydraulic cylinder one end at point H. Rotary bucket hydraulic cylinder opposite end is articulated with rotary bucket one end at point I. Rotary bucket opposite end is articulated with the bucket at point J. Tensioner both ends are articulated with bucket lever and moving jig at points K and L. Relative position of the points of claimed eight-link gear is governed by the following ratios, initial length being kept equal to 1: IK=1; 0.9<AC<1.2; 3.4<AG<3.8; 2<GH<2.4; 6.2<GL<6.8; 2.2<KL<2.5; 2.8<KJ<3.2; 1.6<BJ<1.9; 2.2<BL<2.6; 1.2<DG<1.5; spread HI varies between 5.04 and 9.3, while spread EF varies between 5.03 and 8.9.

EFFECT: higher breakaway force at the same engine power output, acceptable load distribution at machine axle.
