Detailed description of the invention
The present invention is placed on clutch between transmission gear and gear shaft and selector device is part or all of and inside gear shaft, and all types of clutch and speed-changer operation mode are used equally to the present invention.
Below, in conjunction with Figure of description, to be arranged on the lock ring type clutch on output shaft, technical scheme is gone out explanation.
Refer to Fig. 1 (a), Fig. 1 (b), shown in the drawings is the mounting structure of clutch, wherein, the B-B place that cross-section structure shown in Fig. 1 (a) is Fig. 1 (b) cuts open, Fig. 1 (b) is the A-A sectional view of Fig. 1 (a), as it can be seen, low or first gear driven gear 3 and top gear driven gear 6 empty set are on output shaft 1, inner ring gear processing has inner spline gear. Low or first gear driven gear 3 engages with low or first gear driving gear 11, and top gear driven gear 6 top gear driving gear 10 engages.
Low or first gear clutch 4 is arranged between low or first gear driven gear 3 and output shaft 1, and top gear clutch 5 is separately mounted between top gear driven gear 6 and output shaft 1.
Snap ring 2 and snap ring 7 are arranged on output shaft 1, for the axial positioning action of clutch and gear.
Lever 9 is arranged on output shaft by pin 8, and through the slotted eye of output shaft 1, both sides, outer end contact with high low-speed clutch external friction steel disc respectively, and the inside of output shaft 1 is stretched in the inner. Can pass through steering force promotes lever 9 to move left and right, and compresses corresponding clutch and makes it engage, thus realizing the power transmission of different gear.
When neutral position, lever 9 is in centre position, and high low-speed clutch is not subject to the pressure of lever 9 and is in released state, and high low or first gear driven gear is in idling conditions on output shaft 1, it does not have power transmits.
As shown in Figure 2, when being linked into low or first gear, lever 9 makes its inner move to right under steering force promotes and rotates counterclockwise around pin 8, lever 9 outer end and to move to left compression low or first gear clutch 3, low or first gear driven gear 3 is made to be connected with output shaft 1, power is delivered to low or first gear driven gear 3 by low or first gear driving gear 11, then through tension low or first gear clutch 3 to output shaft 1, it is achieved the power transmission of low or first gear.
As it is shown on figure 3, to be linked into height when hastening grade, its process is consistent with being linked into the height shelves that hasten, and is different in that lever 9 makes its inner move to left under steering force promotes. Power hastens grade driving gear 10 to low or first gear driven gear 6 through height, and is delivered to output shaft 1 again by top gear clutch 5, it is achieved the power transmission of top gear.
Operating mechanism specific embodiment below in conjunction with clutch carries out applied analysis. Special instruction, present invention could apply in the gear shift of numbers of gear steps parallel axes type automatic transmission more than two grades, and specific embodiment described herein only in order to explain the present invention, is not intended that limitation of the present invention.
