Detailed Description
In the present invention, it is to be understood that the term "length"; "Width"; "Up"; "Down"; "front"; "Back"; "left"; "Right"; "vertical"; "horizontal"; "Top"; "bottom" "inner"; "outer"; "clockwise"; "counterclockwise"; "axial"; "planar direction"; the directional or positional relationship indicated as "circumferential" or the like is based on the directional or positional relationship shown in the drawings, and is only for convenience of description and simplified description, and does not indicate or imply that the device or element referred to must have a particular orientation; constructed and operative in a particular orientation and therefore should not be construed as limiting the invention.
As shown in fig. 1, a shift tower waterproof construction, including selector shaft 8, selection shelves boss 3, dust cover 4 and shift tower shroud 6 cup joint on selector shaft 8, the upper end of dust cover 4 and the lower extreme sealing connection of selecting shelves boss 3, the lower extreme of dust cover 4 and the upper end sealing connection of shift tower shroud 6. Adopt the dust cover to cooperate from top to bottom with selecting shelves boss, gear shifting tower shroud and seal, can effectively avoid inside muddy water gets into the gear shifting tower, prevent that the gear shifting tower from becoming invalid.
The shift tower waterproof structure further comprises a shift arm 1 and a shift selecting arm 2, the shift arm 1 is sleeved on the shift shaft 8 and located above the shift selecting boss 3 and fixed through a fastener, the shift selecting arm 2 is arranged in an annular groove formed by the shift arm 1 and the shift selecting boss 3, the upper portion of the shift selecting arm 2 is attached to the shift arm 1, and the lower portion of the shift selecting arm 2 is attached to the shift selecting boss 3. The connection relationship among the shift arm 1, the shift arm 2 and the shift boss 3 is known in the art and will not be described herein.
An annular groove I31 is formed in the gear selecting boss 3, an annular groove II 61 is formed in the gear shifting tower cover cap 6, the upper portion of the dust cover 4 is clamped in the annular groove I31, and the lower portion of the dust cover 4 is clamped in the annular groove II 61. The diameter of annular II 61 is greater than the diameter of annular I31, and dust cover 4 is ripple from the top down and expands large-scale structure, and when selecting shelves from top to bottom, the fold structure on dust cover 4 can compensate the clearance. When the gear selecting shaft moves up and down, the gap between the gear selecting boss and the gear shifting cover cap is made up through the fold change of the dust cover, so that the sealing effect is achieved, and muddy water and impurities are prevented from entering the matching surface of the oil seal and the gear shifting shaft.
