Description
Technical field
The utility model belongs to automobile starting motor technical field, specifically, and the one-way element assembly particularly on automobile starting motor.
Background technique
Automobile starting motor is one of key components and parts on automobile, and actuating motor lost efficacy, and automobile cannot start, and all functions all will lose.One-way element is one of key components and parts of automobile starting motor, and one-way element lost efficacy and will directly cause the function of actuating motor to export, and other component of motor car engine and actuating motor itself may be caused to damage simultaneously.According to incompletely statistics, in actuating motor fail data, there is 20-40% to come from one-way element and lost efficacy.Therefore, improve the reliability of one-way element, namely improve whole actuating motor, and even the reliability of car load.
Actuating motor one-way element has its particularity because of Environmental Conditions.For Environmental Conditions, due to temperature impact, the resistance of motor differs greatly, 4 cylinder gasoline engines of such as 1.5L discharge capacity, doubly, the design of one-way element will take into account simultaneously can transmit maximum forward moment and minimum reverse slipping torque to resisting moment difference 3-5 under normal temperature 20 DEG C and-30 DEG C of states.One-way element in the course of the work, is positively engaging with engine flywheel, and therefore the roller of one-way element inside, spring can bear very large impact force.
Model utility content
Technical problem to be solved in the utility model is the automobile starting motor one-way element assembly providing a kind of good reliability.
The technical solution of the utility model is as follows: a kind of automobile starting motor one-way element assembly, comprise gear (1), cover cap (2), roller (5), spring (6) and star-wheel (8), described star-wheel (8) is made up of the die cavity (8a) of front end and the spline housing (8b) of rear end, the die cavity (8a) of star-wheel (8) front end overlaps cover cap (2) admittedly, and multiple circumferentially equally distributed locating slot is set in the die cavity (8a) of star-wheel (8) front end, roller (5) and spring (6) are all housed in each locating slot, described gear (1) is made up of the teeth portion (1a) of front end and the optical axis portion (1b) of rear end, the optical axis portion (1b) of gear (1) rear end stretches in the die cavity (8a) of star-wheel (8), its key is: be provided with on the front-end face of described die cavity (8a) can be spacing to spring (6) spring stop (4), the ear end face of this spring stop (4) and the front-end face of described die cavity (8a) are fitted, the front-end face of spring stop (4) is spacing by catch (3), described catch (3) is installed in the optical axis portion (1b) of gear (1).
Adopt above technological scheme, spring stop can the mobile space of restraining spring, prevents spring from overturning, thus effectively prevent one-way element can not carry-over moment because forward skids, ensure that the reliability of one-way element.Spring stop is positioned at the front-end face of star-wheel die cavity by catch, not only easy accessibility, quick, and between spring stop and star-wheel, laminating is closely, respond well to spring retainer.
In the die cavity (8a) of described star-wheel (8) front end, arrange six circumferentially equally distributed locating slots, correspondingly roller and spring are provided with six right, can transmit larger moment like this.
The front-end face of described spring stop (4) is spacing by two symmetrically arranged catch (3), and this catch (3) is semi-circular shape, and is installed in the annular groove in gear (1) optical axis portion (1b).The moulding of above structure catch is simple, is easy to processing and fabricating, easy accessibility, and the good reliability spacing to spring stop.
In described die cavity (8a), be embedded with gear oil cap (7), this gear oil cap (7) is positioned at the front port place of spline housing (8b).Gear oil cap can reduce lubricating grease and run off, and the die cavity of lubricating grease to roller and gear and star-wheel plays good lubrication, to reduce wear, improves reliability and the working life of one-way element further.
Described spline housing (8b) is set with apical tooth spring (9), the front end of this apical tooth spring (9) abuts with the ear end face of die cavity (8a), the rear end of apical tooth spring (9) abuts with shift fork snap ring (10), and the back-up ring (11) that described shift fork snap ring (10) is set with by spline housing (8b) rear end is spacing.Apical tooth spring plays buffer function when starter motor works, and reduces the impulsive contact force of gear mesh engine flywheel, thus reduces the damage of gear and engine flywheel.
The external annulus of described die cavity (8a) is provided with multiple groove, and cover cap (2) is provided with the fin with fit depressions, and described cover cap (2) is fixed by riveted joint and die cavity (8a).It is firm that above structure cover cap is connected with star-wheel, can prevent cover cap in one-way element work from occurring to loosen or throw off.
, forward can not be there is and skid, good reliability in beneficial effect: the utility model carry-over moment is large; Particularly require the extra high automobile starting motor of reliability for cold area, adopt this one-way element assembly, forward carry-over moment can reach more than 110N.m, can improve 2-3 working life doubly simultaneously.
