Abstract
The utility model relates to a thick-wall clutch sleeve for a speed changer, which comprises a cylindrical sleeve barrel seat and a thick-wall clutch sleeve, wherein the center of the cylindrical sleeve barrel seat is provided with a shaft hole, one end of a thick-wall sleeve barrel is fixed to a ring surface of the rear end of the cylindrical sleeve barrel seat, and the thick-wall sleeve barrel and the cylindrical sleeve barrel seat are in an integral structure. A plurality of ratchet pawl outlets which are arranged in a line at uniform intervals are arranged on the barrel wall of the thick-wall sleeve barrel. A pin shaft hole is drilled in the barrel wall of the thick-wall sleeve barrel in a horizontal direction. The thick-wall clutch sleeve can be combined with a bevel gear assembly, or a ratchet pawl assembly, etc. to form a speed changer of a speed changing bicycle. The speed changer has the advantages of simple operation, stable performance, small chain wheels, etc.
Description
The utility model relates to a kind of clutch cover of change-speed box, particularly relates to a kind of heavy wall clutch cover that is used on the internal speed variator of bicycle.
Along with developing rapidly of China's economic construction, urban and rural transportation has obtained very big improvement, and Advanced Sedan Car enters the strange thing that family neither make us gasp in admiratioing.Yet at present, or in the quite a long time, bicycle is still the national main vehicle used in everyday, and variable speed bicycle is a kind of bicycle that the young and the middle aged misses potter in bicycle.At present its change-speed box of variable speed bicycle of producing is to adopt to be contained in gear assembly that each tooth radius on the axis varies in size and to cooperate with chain and finish speed change, there are a lot of shortcomings in this speed change, exposed outside as the variable gear assembly, promptly not attractive in appearance, fragile again, the variable speed operation underaction, the speed change gear is few etc.
The purpose of this utility model is to provide a kind of at the problems referred to above to be sleeved on the axis, and carries out the change-speed box heavy wall clutch cover of shift speed change with unit constructions such as variable gear assembly and pawl assemblies.
The purpose of this utility model realizes by following technical scheme, that is:
Change-speed box heavy wall clutch cover comprises cylindrical sleeve seat and thick-walled sleeve.The center of cylindrical sleeve seat is provided with axis hole, and the diameter of axis hole is greater than the internal diameter of thick-walled sleeve, and less than the external diameter of thick-walled sleeve.One end of thick-walled sleeve is fixed on the anchor ring of cylindrical sleeve base rear end face, and with the cylindrical sleeve seat be an integral structure, the barrel of thick-walled sleeve is provided with a plurality of word orders and ratchet outlet uniformly at interval, horizontal direction is drilled with a pin shaft hole in the barrel upper edge of thick-walled sleeve, and pin shaft hole runs through each ratchet outlet.
The barrel of above-mentioned thick-walled sleeve is provided with the ratchet outlet that upper and lower two row mutual correspondences and along continuous straight runs are distributed in distance, and the barrel upper edge horizontal direction of the thick-walled sleeve in every row's ratchet exit is drilled with pin shaft hole.
The barrel of above-mentioned thick-walled sleeve is provided with the ratchet outlet of a plurality of different azimuth, and the barrel in each ratchet exit is provided with pin shaft hole.
The utility model can be used as the clutch cover that the internal speed-changing of variable speed bicycle is used, also can on other change-speed box, use, the utility model can be sleeved on the axis of inner speed change bicycle, with unit constructions such as bevel gear component or pawl assemblies, constitute the change-speed box of variable speed bicycle, advantages such as that this variable speed bicycle has is simple to operate, stable performance, sprocket wheel is little, gear is many, shift speed change is convenient.
Fig. 1 is the structural representation of first kind of embodiment of the present utility model, and Fig. 2 is the right elevation of Fig. 1, and Fig. 3 is second kind of embodiment scheme drawing of the present utility model, and Fig. 4 is the right elevation of Fig. 3, and Fig. 5 is the third embodiment scheme drawing of the present utility model.The utility model is described in further detail below in conjunction with accompanying drawing.
