 Jump file transmission failure phenomenon: the car is moving to jump back in the automatic shift lever neutral position. This phenomenon occurred in the high-speed, sudden changes in load or vehicle subject to severe vibration, and most of the stalls in the high jump file.

    Transmission jumps file causes for the failure:

    l, the gear, gear synchronizer cone sets or excessive tooth wear, tooth length along the direction of the formation of embryo, when it engages an axial thrust generated in the work but also by vibration shaking the inertia of speed changes, forcing the meshing disengage gear along the axis;

    2, the transmission and bending deformation, wear off very, gear lever screw loose or deformed, so that the gear is not properly engaged;

    3, self-locking device worn Songkuang, lack of spring stretch or break, resulting in lack of strength lock, so that can not be reliably shift fork shaft positioning;

    4 sets of gear tooth wear off, or even along the length direction of ground into a conical teeth;

    5, shaft and bearing wear serious, the axial clearance is too large, or the first and second shaft and intermediate shaft is not parallel, so that can not properly meshing gears caused by jumping up and down swing file;

    6 spline shaft gear teeth and grooves of the spline sliding wear off even;

    7, the second axis distortion spline or key tooth wear transition, caused by loose nuts before and after the channeling shaft or gear drive;

    8, loosen the lock pin synchronizer, synchronization, fall apart or the length of engagement teeth have been worn out;

    9, the transmission is not firmly fixed.

    Jump file transmission and elimination of Faults:

    l, jump in that file in a file when the file will still stick shift substitutions, and then remove the transmission gear mesh cover to see the situation, such as meshing well, should check the shift fork shaft lock mechanism;

    2 files by hand to promote the shift fork jump test positioning device, such as poor positioning, need to remove the shift fork shaft inspection and positioning the ball and spring, as spring is too soft or broken should be replaced. If the shift fork shaft groove wear and tear should be repaired or replaced over even;

    3, check the meshing gears, such as the gear is not fully engaged, hands to promote the dance gear or gear sets of files can be properly engaged, you should check for bent or worn shift fork over even, and the variable speed screw is loose the fork, the fork end with the gear cast slot gap is too large. If the shift fork bent should be corrected; as a result of wear and sliding the lower speed gear fork over Songkuang tank repair should be removed;

    4, such as the speed change mechanism well and gear or gear sets can properly engaged, you should check into a cone-shaped gear is worn, such as badly worn should be replaced;

    5, check the bearing and shaft wear, severe wear and tear such as shaft, bearing Songkuang or variable speed axial movement along the axis, should be removed to repair or replace;

    6, check synchronizer work, if any fault should be repaired or replaced;

    7, check the transmission mounting bolts, such as loose should be tightened
