Abstract
A novel one-way device of starter of automobile engine is provided, which executes no change on the circular shape and size of the prior one-way device in various specifications and models, and has the prior roller together with an inside structure removed and changed into a new structure proposal that a return spring assists a clutch to separate and assists a meshing tooth to mesh and drive a flywheel transmission gear 14 to rotate. The product of the utility model has no friction and wear, and can be very long in life-span. The products manufactured by adopting the technology in various specifications and models are completely same in the shape and size of the prior products in various specifications and models, and can directly replace the prior products.
Description
Technical field
The utility model relates to a kind of auto parts machinery, the automotive engine starter one-way element between particularly a kind of motor vehicle starting motor and the motor.
Technical background
The automotive engine starter one-way element has another name called the motor tooth.
Nearly all motor, particularly various automotive engineering mechanical starter one-way elements, and generator set one-way element all need to use the motor one-way element.Its effect is when lighting starting motor, shift fork draws close one-way element to flywheel teeth, is critical in its inside, flywheel engaging tooth 14 rotates, thereby the flywheel that drives motor rotates, when driving the engine spindle rotation, make the cylinder igniting promote engine rotation, so the motor of Motor Vehicle is started working.Motor is worked at the beginning, and starting electrical machinery stops operating immediately, and when shift fork was pushed one-way element aside, one-way element inside was become flexible, unclamped because of reverse.
At present not only China, the employed one-way element of many countries all is roller types in the world, by inclined-plane relative with spring (degree of tightness) orientation, it can be critical when being rotated in the forward, the structural principle that unclamps during contrary the rotation reaches the purpose of unidirectional rotation.For decades, use till today always.Its deficiency is: the roller diameter is easy to wearing and tearing, because the moment that is starting, high engine speeds is rotated, the flywheel diameter of motor is bigger tens times than one-way element driving cog 14 diameters, when driving the rotation of one-way element engaging tooth conversely, though reverse one-way element inside is unclamped, powerful inertia still makes one-way element roller high speed rotating and causes wearing and tearing.Every startup once just suffers once to wear and tear, and roller attenuates because of wearing and tearing in the course of time, can not forward rotation and can't drive engine flywheel and rotate thereby produce one-way element driving cog 14.So-called starter motor skids, and not start be exactly this principle.
This also be one-way element be assorted petty be the starter motor reason of flimsy accessory.
Summary of the invention
The purpose of this utility model is that disclosing a kind of can being rotated in the forward to the public is critical, and contrary rotation is unclamped, and form structure does not change, and internal structure is reformed, and never wornout type and processing are easier to, the automotive engine starter one-way element of lower cost.
The technological scheme that the utility model adopted is:
The profile of all size and model one-way element and size need not done any change, remove roller, spring and corresponding construction thereof in the existing one-way element outer cover, the employing return spring separates clutch and adopts the engaging tooth engagement to drive the technological scheme of flywheel driving cog 14 rotations.As shown in Figure 1, clutch is made of last engaging tooth parts and following engaging tooth parts, and return spring 12 is between last engaging tooth parts and following engaging tooth parts.
Concrete technical measures are as follows:
Last engaging tooth parts are made of last engagement toothholder 8, motor rotor axis hole 1, return spring 12, return spring jump ring 9 and engaging tooth 10, external diameter at motor rotor axis hole 1, structural order from top to bottom is jump ring 2, packing ring 3, outer spring cover 5, outer spring 6 and packing ring 7, and is made of the fork slot 4 that forms between 5 and 3.
The structure of following engaging tooth parts be by outer cover 13, in following engaging tooth 11 is arranged, and down engaging tooth 11 is as a whole with flywheel driving cog 14; Last engaging tooth 10 and following engaging tooth 11 corresponding cooperations.
The internal diameter of outer cover 13 has engaging tooth separating vessel 16 and the engaging groove 17 that matches with convex tendon 15 on last engagement toothholder 8 external diameters.Outer cover 13 can be made independent shell, in order to seal upper and lower engaging tooth.
The utility model can be used for the generator set Starter.
The novel advantage of this reality is:
1, because there is not any friction in the utility model product, that is to say there are not wearing and tearing that its life-span can be very permanent, thereby reduce driver's many troubles and a large amount of economic loss.
2, because more simple in structure than the existing product, processing and assembly technology are all than being easier to, and man-hour, material, cost are saved greatly.
3, use this product can reduce with reaching, improved the working life of whole starter motor the carbon brush of starter motor, the wearing and tearing of copper sheathing.
4, adopt the product of the various model specifications that present technique makes, just the same with the external form and the size of existing various model specification products, can directly replace existing product.
The utility model is described in further detail below in conjunction with description of drawings and embodiment:
Working principle of the present utility model is: when the automobile starting motor, shift fork presses flywheel teeth by outer spring 6 with starting motor rotary shaft hole 1, engaging tooth 10,11 rotates simultaneously up and down, and drive flywheel engaging tooth 14 rotates and the flywheel of driving automobile motor rotates, and starts working at the motor of Motor Vehicle.Starting electrical machinery stops operating immediately simultaneously, and when shift fork was pushed one-way element aside, one-way element became flexible, unclamps because of the effect of return spring 12.
Description of drawings
Fig. 1 is this real new structure generalized section.
Fig. 2 is that Fig. 1 part separates solid and outer spring and return spring position view.
Wherein: 1, motor (starting motor) rotary shaft hole; 2, jump ring; 3, packing ring; 4, dial draw-in groove; 5, outer spring cover; 6, outer spring; 7, packing ring; 8, mesh toothholder on; 9, inner spring jump ring; 10, go up engaging tooth; 11, following engaging tooth; 12, return spring; 13, outer cover; 14, engine flywheel driving cog; 15, convex tendon; 16, engaging tooth separating vessel; 17, engaging groove.
Embodiment
