The crown of described damping tooth is blunt nosed shape, and the diameter L transition fit size relationship of the crown place diameter of a circle D of multiple damping tooth and the connector rod of automobile gear shifting inhaul cable is-0.1mm ~+0.05mm.
Adopt technique scheme: a kind of damping cap for automobile gear shifting inhaul cable, comprise cap body, the positioning hole for being fixedly connected with the sleeve cap guide pipe of automobile gear shifting inhaul cable is provided with in described cap body, and the via hole for passing for the connector rod of automobile gear shifting inhaul cable, the shaft axis of described positioning hole and the shaft axis of via hole are located along the same line, positioning hole and via hole are connected to form shoulder hole, damping cap by the end axis of positioning hole and automobile gear shifting inhaul cable sleeve cap guide pipe to being fixedly connected with, the tube chamber shaft axis of automobile gear shifting inhaul cable sleeve cap guide pipe and the shaft axis of via hole are located along the same line, the connector rod of automobile gear shifting inhaul cable extends sleeve cap guide pipe, when the extending end of connector rod passes the via hole of damping cap, the centering of via hole docking head rod, effectively prevent connector rod eccentric, reduce the wearing and tearing to sleeve cap guide pipe when connector rod slides axially.The hole wall of described via hole is circumferentially evenly provided with multiple damping tooth towards shaft axis projection, these damping teeth extend along the axis of via hole, with the connector rod transition fit of automobile gear shifting inhaul cable, pass in the vestibule that connector rod is formed at multiple damping tooth, damping tooth docking head rod plays support, absorbing effect, keep connector rod and damping cap, the coaxality of sleeve cap guide pipe, greatly reduce the noise that automobile gear shifting inhaul cable end produces when shifting gears simultaneously, because the axis of damping tooth along via hole extends, connector rod is when facing sleeve cap guide pipe slides axially, the resistance of these damping teeth docking head rod is less, do not affect gear shift operation.
The hole wall of described positioning hole is provided with the axle positioning boss of annular, axle positioning boss coordinates with the positioning ring groove of automobile gear shifting inhaul cable sleeve cap guide pipe end, damping cap is axially fixed on the sleeve cap guide pipe of automobile gear shifting inhaul cable, form axial restraint, damping cap can rotate around sleeve cap guide pipe.The side that described axle positioning boss is positioned at positioning hole opening is the conical surface, the opposite side of axle positioning boss is vertical surface, in the process that damping cap is connected with sleeve cap guide pipe end, the axial end of the conical surface to automobile gear shifting inhaul cable sleeve cap guide pipe is stepped down, be convenient to damping cap sleeve on the sleeve cap guide pipe of automobile gear shifting inhaul cable, after damping cap is in place, the vertical surface of axle positioning boss opposite side adds in the positioning ring groove snapping in automobile gear shifting inhaul cable sleeve cap guide pipe, form axially locating, effectively prevent damping cap and sleeve cap guide pipe from departing from.
The crown of described damping tooth is blunt nosed shape, and the diameter L transition fit size relationship of the crown place diameter of a circle D of multiple damping tooth and the connector rod of automobile gear shifting inhaul cable is-0.1mm ~+0.05mm.Damping tooth contacts with automobile gear shifting inhaul cable connector rod, damping tooth slight deformation, and centering, the shock attenuation result of docking head rod are better.
Be further described below in conjunction with the drawings and specific embodiments.
