Abstract
The utility model relates to a starting device for a freewheel clutch in an external friction starting automatic unloading type, comprising a casing 1 and a starting chain wheel connected with a shaft chain wheel of a starting motor through a chain or a staring gear disk 4 engaged with a shaft gear of the starting motor. The utility model is characterized in that the chain wheel or the gear forms a combined starting and unloading device, together with a friction disk sleeve 5, a shaft sleeve 7 and a flat spring 6a or a cone 8, a conical sleeve 9 and a flat spring 6b; the combined starting and unloading device is positioned in a ring of a body 2 fixed to a freewheel of a magneto of a motor; a roller or a rolling ball 3 which can automatically reset is arranged between the shaft sleeve 7 or the conical sleeve 9 and the body 2; when the shaft sleeve or the conical sleeve rotates, the dynamic friction is transmitted to the body through the roller.
Description
The utility model relates to the electric starter of motorcycle, and particularly a kind of external friction starts automatic unload-type free wheel device starting drive.
Free wheel device is widely used in all kinds of motorcycles as a kind of typical motorcycle electric starter, but for the material of making free wheel device, required precision is very high, with reliability, reduction noise, the life-saving of safeguard work; ; because motor is subjected to the influence of various factors in start-up course; often because of not starting by normal ignition; and taking place, the moment counterrotating promptly recoils; its huge anti-power of work all acts on the free wheel device; cause the damage of clutch; thereby destroying on the clutch gear that transmits in the start-up system or chain and starting electrical machinery as the transfer function because of power causes whole start-up system to lose efficacy; for addressing this problem employing reverse reduction valve is installed in motor abroad, i.e. air valve is opened unloading and is protected starting drive during motor recoil.
The purpose of this utility model be to provide a kind of can behind engine start, take place anti-) in the time unload automatically; thereby protection starting drive; and make the precision of this starting drive, and reliability, the external friction that the life-span is greatly improved starts automatic unload-type free wheel device starting drive.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, be that a kind of external friction starts automatic unload-type free wheel device starting drive, comprise housing, the startup sprocket wheel that is connected with starting electrical machinery axle sprocket wheel by chain or with the startup fluted disc of starting electrical machinery shaftgear engagement, it is characterized in that: described sprocket wheel or gear and friction disk cover, axle sleeve and plane spring, or and cone, tapered sleeve and plane spring constitute combination and start and feel trim actuator, this combination starts and feel trim actuator is positioned at and the fixing body ring of motor magnetogenerator flywheel, automatically reset roller of energy or ball are installed between described axle sleeve or tapered sleeve and the body, when axle sleeve or axle sleeve rotation, dynamic friction are passed to body by roller.
Said structure of the present utility model is further specified by the embodiment that accompanying drawing provides.
The utility model has following accompanying drawing:
Accompanying drawing 1 is the utility model embodiment 1 structure step profile figure;
Accompanying drawing 2 for the B of Fig. 1 to partly cuing open schematic representation;
Accompanying drawing 3 is the utility model embodiment 2 structure step profile figure;
Accompanying drawing 4 is the structural representation of embodiment's 1 Intermediate shaft sleeve 7;
Accompanying drawing 5 is the structural representation of tapered sleeve 9 among the embodiment 2.
Referring to accompanying drawing: the external friction among the figure starts automatic unload-type free wheel device starting drive, comprise housing 1, the startup sprocket wheel that is connected with starting electrical machinery axle sprocket wheel by chain or with the startup fluted disc 4 of starting electrical machinery shaftgear engagement, it is characterized in that: described sprocket wheel or gear and friction disk cover 5, axle sleeve 7 and plane spring 6a, or with cone 8, tapered sleeve 9 and plane spring 6b constitute combination and start and feel trim actuator, this combination starts and feel trim actuator is positioned at body 2 rings fixing with motor magnetogenerator flywheel, automatically reset roller of energy or ball 3 are installed between described axle sleeve 7 or tapered sleeve 9 and the body 2, when axle sleeve or axle sleeve rotation, dynamic friction are passed to body by roller.
In the embodiment 1 shown in the accompanying drawing 1,2,4, combination starts and feel trim actuator comprises friction disk cover 5 is threaded with axle sleeve 7, and plane spring 6a will start sprocket wheel or startup fluted disc 4a and lean at friction disk and overlap on 5, drive its rotation by frictional engagement.
Shown in the accompanying drawing 3,5; Among the embodiment 2, the startup sprocket wheel that combination starts and feel trim actuator comprises or be threaded with cone 8 with starting fluted disc 4b, tapered sleeve 9 is enclosed within on the cone, and plane spring 6b is supported between cone and startup sprocket wheel or the startup fluted disc 4b.
Referring to accompanying drawing 4,5, the cylindrical that an embodiment of the present utility model is axle sleeve 7 or tapered sleeve 9 is many plush coppers wheel body, the plush copper circumference in equal parts, and identical with roller or ball 3 numbers.
In another embodiment of the present utility model, have the gradually fluting of five equilibrium inner circumference on the body 2, roller or ball 3 are positioned at groove.
Plane spring 6 in the above-described embodiments can be butterfly spring, wave mode spring etc.Described automatically reset ball or roller 3 reset by the spring pin assembly 10 that is installed in body 2.
Working procedure of the present utility model is: when normal ato unit, motor transmits torsion and drives that combination starts and the feel trim actuator rotation, and drives the body rotation by the roller friction, makes magnetogenerator rotation and the ato unit work of being fixed together with it., motor produces moment if failing normal the startup during recoil force; roller passes to combination with recoil force and starts and feel trim actuator; this moment since with the tapered sleeve 9 of cone 8 rubbing contact; or to overlap the startup sprocket wheel of 5 rubbing contact with friction disk or start fluted disc 4a be at the descending friction pair that becomes certain force of the pressure of plane spring 6; because power is greater than frictional force instead); make tapered sleeve 9 with respect to starting sprocket wheel or starting fluted disc 4a relative movement take place with respect to cone 8, friction disk cover 5; thereby realize the overburdening unloading, protected whole starting drive.
