Abstract
The utility model relates to a one-way device for an automobile starter. The one-way device for the automobile starter comprises a first gear (1), a second gear (3), a spline shaft (6) and a sleeve barrel (2). A plurality of wedge grooves (7) are arranged on the second gear (3). Each wedge groove (7) respectively comprises a head end face (7 and 5), a first side face (7 and 4), a second side face (7 and 3) and a tail end face (7 and 2). A spring (4) and a rolling column (5) are respectively arranged in each wedge groove (7). One end of the spring (4) abuts against the rolling column (5). The other end of the spring (4) abuts against the tail end face (7 and 2). The external end of each tail end face (7 and 2) is provided with a protrusion (7 and 1) used for preventing the spring (4) from sliding out of the wedge grooves (7). The spring in the wedge grooves under stress does not slide out of the wedge grooves (7) and cause failure.
Description
Technical field
The utility model relates to the auto parts machinery field, specifically is a kind of one-way element that is used for automobile starter.
Background technique
One-way element is overrunning clutch again, is the critical component of automobile starter, and its main effect is that the moment of torsion that the motor of starter motor produces is passed to the motor car engine flywheel.Like Fig. 1, shown in Figure 2; One-way element mainly comprises in first gear 1, second gear 3, splined shaft 6 and sleeve 2, the second gears 3 and is provided with a plurality of wedge slots 7, and each wedge slot 7 includes head end face 7.5, first side 7.4, second side 7.3 and breech face 7.2; Be equipped with spring 4 and roller 5 in each wedge slot 7; One end and the roller 5 of spring 4 offset, and the other end of spring 4 and breech face 7.2 offset, because the breech face 7.2 of existing one-way element wedge slot is the plane; This kind structure is when spring stress, and spring tends to skid off breech face and causes one-way element to lose efficacy.
Summary of the invention
The utility model technical problem to be solved is: can not skid off wedge slot when the spring stress in a kind of wedge slot is provided and the one-way element that is used for automobile starter that causes losing efficacy.
The technological scheme that the utility model is taked is: a kind of one-way element that is used for automobile starter is provided; Comprise first gear, second gear, splined shaft and sleeve, be provided with a plurality of wedge slots in second gear, each wedge slot includes head end face, first side, second side and breech face; Be equipped with roller and spring in each wedge slot; One end and the roller of spring offset, and the other end and the breech face of spring offset, and the outer end of said breech face is provided with and is used to prevent that spring from skidding off the convexity of wedge slot.
After adopting this structure; The utility model is used for the one-way element of automobile starter to be compared with existing technology, and following advantage is arranged: because the outer end of breech face of wedge slot is provided with and is used to prevent that spring from skidding off the convexity of wedge slot in the one-way element, when the spring in the wedge slot when stressed; Spring can produce on breech face and slide; This moment, the spring convexity that can be provided with propped up, and can not skid off wedge slot and caused spring to compress the roller failure, and then cause the inefficacy of one-way element.
As improvement, the angle of the described breech face and second side can avoid spring to skid off wedge slot less than 90 ° less than 90 ° more effectively.
As further improvement, the angle of the described breech face and second side is 85 °, does not influence spring and breech face offsets, and is preferred embodiment.
Description of drawings
Fig. 1 is a starter motor one-way element structural representation.
Fig. 2 is the inner structural representation of starter motor one-way element second gear.
Among the figure, 1, first gear, 2, sleeve, 3, the second gears, 4, spring, 5, roller, 6, splined shaft, 7, wedge slot, 7.1, convexity, 7.2, breech face, 7.3, second side, 7.4, first side, 7.5, the head end face.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Like Fig. 1, shown in Figure 2, the utility model works the one-way element that is used for automobile starter, comprises first gear 1, second gear 3, splined shaft 6 and sleeve 2; Be provided with a plurality of wedge slots 7 in second gear 3; Each wedge slot 7 includes head end face 7.5, first side 7.4, second side 7.3 and breech face 7.2, is equipped with spring 4 and roller 5 in each wedge slot 7, and an end and the roller 5 of spring 4 offset; The other end of spring 4 and breech face 7.2 offset; The outer end of breech face 7.2 just is provided with away from an end of wedge slot 7 on the breech face 7.2 and is used to prevent that spring 4 from skidding off the convexity 7.1 of wedge slot 7, and this protruding 7.1 arc surface by head end face 7.5 arc transition of the breech face 7.2 of wedge slot 7 and another wedge slot 7 forms; The angle of the breech face 7.2 and second side 7.3 adopts 85 ° less than 90 ° in this example.
Claims (3)
1. one-way element that is used for automobile starter; Comprise first gear (1), second gear (3), splined shaft (6) and sleeve (2); Second gear (3) is provided with a plurality of wedge slots (7); Each wedge slot (7) includes head end face (7.5), first side (7.4), second side (7.3) and breech face (7.2); Be equipped with spring (4) and roller (5) in each wedge slot (7); One end of spring (4) and roller (5) offset, and the other end of spring (4) and breech face (7.2) offset, and it is characterized in that: the outer end of said breech face (7.2) is provided with and is used to prevent that spring (4) from skidding off the convexity (7.1) of wedge slot (7).
