Abstract
The utility model relates to a separation and combination mechanism which comprises a shell and a separable shifting fork, wherein a rolling bearing is arranged below the separable shifting fork and fixed between two brackets by a cylindrical shaft; the two brackets are respectively arranged at two sides of the separable shifting fork, and the bottom and the rolling bearing is in contact with the shell; alternatively, the two brackets are arranged on the shell respectively, and the top of the rolling bearing is in contact with the separable shifting fork; and the middle part of the cylindrical shaft is in interference fit with the inner ring of the rolling bearing, and the cylindrical shaft and the two brackets are in clearance fit. The separation and combination mechanism has the beneficial effects that sliding friction pairs among the separable shifting fork, spherical support pins and the shell are changed into rolling friction pairs so as to reduce efficiency loss, and the multi-degree of freedom of the spherical surface is reduced so as to enhance the stability, avoid the abrasion of the separable shifting fork and the spherical support pins, eliminate abnormal sound, thereby being green and environment-friendly, and enhancing the operation stability and driving comfortableness.
Description
Technical field
The utility model relates to a kind of separation combined mechanism.
Background technique
Automobile is with gear-boxes such as gearbox, speed reducer or main reducing gears, in gearshift or when turning to, and the power that needs interruption to transmit from motor, the mechanism that realizes this function is the acting in conjunction of separating mechanism and clutch.Separating mechanism the most commonly used at present mainly is made up of disengaging yoke (separator levers), sphere support pin and housing etc.Groundwork form and principle are: disengaging yoke has a spherical groove to cooperate with the sphere support pin; The sphere support pin is installed on the housing; Disengaging yoke is a fulcrum to separate support pin; Through being slidingly matched between the ball-and-socket of sphere support pin sphere and disengaging yoke, realize the motion of separating mechanism or the separation of power.
But find that through practical application and investigation above-mentioned existing technology structural type cooperates because of adopting the rotation of sliding, under the effect of Separating force, rotation process is very not steady, and is prone to wearing and tearing; Use a period of time after power combines, Panasonic's clutch does not receive abnormal sound very easily to occur under the state of active force; Influence working environment; The stationarity that causes simultaneously controlling and the travelling comfort of driving are poor, finally cause client to complain, bring undesired image and bigger loss after sale to enterprise.
The model utility content
The utility model is used to solve the deficiency of above-mentioned technology and a kind of separation combined mechanism is provided, and has avoided the phenomenon that the existing technology structure is very not steady because of the rotation of adopting the rotation cooperation of sliding to cause, be prone to wearing and tearing and abnormal sound very easily occurs.The purpose of the utility model is to realize through following technological scheme:
A kind of separation combined mechanism comprises housing and disengaging yoke, and the below of said disengaging yoke is provided with rolling bearing, and rolling bearing is fixed between two supports through cylinder axis.
Said two supports are arranged at the both sides of disengaging yoke respectively and the bottom of rolling bearing contacts with housing.
Selectively, said two supports are arranged on the housing respectively and the top of rolling bearing contacts with disengaging yoke.
One end of said cylinder axis is provided with the retaining cap, and the retaining cap is resisted against the outside of one of them support, and the other end of cylinder axis passes another support.
The said the other end of said cylinder axis is provided with draw-in groove near said another support place, is fixed with the outside that snap ring and said snap ring are fixed on said another support on the said draw-in groove.
Said cylinder axis middle part and rolling bearing inner ring interference fit, Spielpassung between said cylinder axis and said two supports.
The beneficial effect of the utility model is: the sliding friction pair between disengaging yoke and sphere support pin is changed into rolling friction pair; Reducing loss in efficiency, and the multi-freedom degree of sphere is reduced, to strengthen stationarity; Avoid the wearing and tearing of disengaging yoke and sphere support pin; Eliminate abnormal sound, environmental protection has strengthened the stationarity controlled and the travelling comfort of driving.
