Also one-way element can be used when shifting gears, when by top gear shift to low gear, because output shaft just departs from high gear, so output shaft still has a higher rotating speed, therefore after output shaft is connected with low speed gear, making output shaft and low speed gear have an identical speed just needs output shaft to have a moderating process, otherwise output shaft will oppositely drive low speed gear to rotate, or make low speed gear occur beating tooth phenomenon, thus impact is formed to gear, make gear damaged rapidly, therefore in electric motor car, also one-way element is provided with, prevent output shaft from oppositely driving low speed gear.
Therefore unidirectional application area is extremely wide, and at present, in major part one-way element, shell and outer shroud are all adopt friction tight mode to assemble, shell and outer shroud, in Long-Time Service process, can loosen, and the micro-strain of shell all can cause between shell and guide cylinder and departs from home position, affect the working life of one-way element, cause the potential safety hazard of car steering.Although there is partial automobile motor one-way element to be provided with shell anti-drop structure, for the factor such as manufacture cost, mounting process; Although also there are some simple anti-drop structures, be not easy to assembling, and anticreep poor effect.
Summary of the invention
The invention is intended to provide a kind of one-way element with anti-shell dropping structure, this one-way element with anti-shell dropping structure can effectively stop shell to come off or loosen, and extends one-way element working life.
The one-way element of the anti-shell dropping structure of base case band of the present invention, comprises shell, outer shroud, inner ring, stage clip, roller; Described outer shroud and inner ring are circle structure, and inner ring, stage clip and roller are all arranged in outer shroud; Described outer shroud is stepped, and has conical surface transition from large end to small end; Shell is tubular and overlaps the large end of outer shroud, the closing in and shell is stamped, and is fitted on the conical surface of outer shroud; The outer circumferential face of the large end of described outer shroud is provided with multiple spacing hole, and on shell, is provided with the positioning hole corresponding to spacing hole, and the periphery of positioning hole dents into downwards in positioning hole.
This base case, when mounting casing, should first process spacing hole and positioning hole, then casing is located at the large end of outer shroud, and carries out reducing with stamping press to shell, makes shell be adjacent on the conical surface of outer shroud; Then rotation case, makes circular hole on shell aim at spacing hole on outer shroud, then uses the positioning hole in pin alignment housings, and knocks pin and make casing deformation to lower recess, thus effectively strengthens the connection of shell and outer shroud.
This programme not only effectively extends the working life of one-way element, and the simple structure of the anti-drop structure of this shell, and easy processing has saved material and time cost; But also can prevent shell and outer shroud from relatively rotating, thus the connection effect of multidirectional enhancing shell and outer shroud, reduce the burden of shell reducing place.
Preferred version one, as the further optimization to base case, described spacing hole is taper hole, and the periphery of described positioning hole is fitted on the conical surface of spacing hole; Spacing hole is set to taper hole, is conducive to the amount of deformation of the positioning hole periphery controlled on shell, thus when avoiding im-pact location hole, positioning hole is out of shape excessive, thus destroys shell; Or make the intensity step-down of positioning hole periphery, thus make positioning hole very easily destroyed, thus do not reach consolidation effect.
Preferred version two, as the further optimization to base case, is provided with a rubber sleeve between described shell and outer shroud; Rubber sleeve has buffer function to shell, and when can avoid shaking, shell and outer shroud directly collide, thus the distortion of aggravation shell.
Preferred version three, as the further optimization to base case, the conical surface section described shell corresponding to described outer shroud has offered multiple circular hole; When shell is stamped and closes up, due to distortion, so enclosure interior leaves internal stress, therefore very easily produce breakage in the case of a shock, and offer at deformation section the effect that circular hole has elimination internal stress.
