Abstract
The utility model discloses an overrunning clutch, which is composed of a disc shell, an inner star wheel, a roller, an oil sealing assembly, etc. The utility model adopts a magnetic roller in a ratchet of the inner star wheel so as to replace a supporting spring in an original technique, the utility model solves the disadvantages that the supporting spring fatigues easily or is easy to be broken caused by the contact friction with the roller for a long time and the supporting spring can not normally work, and the utility model assures safe operation. Therefore, the utility model has the advantages of simple structure, convenient installation and disassembly, good reliability, safe use, etc.
Description
Technical field
The utility model relates to a kind of free wheel device.
Background technique
Free wheel device is installed between automobile gearbox and the motor and plays interconnect function, tramps with one's feet during starting, does not need stepping on clutch just can realize gear shift when travelling.Free wheel device is the clutch that a kind of speed of related movement by driving and driven part changes or the conversion of gyratory directions can engage automatically or throw off.Present free wheel device can be divided into pawl type and friction type.Pawl type free wheel device simple in structure, easy to manufacture, the reliability height impacts and noise but have when engaging, and is usually used in the less occasion of speed discrepancy; Roller-type overrunning clutch in the friction overdrive clutch, by the dish shell, star-wheel, roller, part such as Oil sealing assembly and supported spring is formed, its smooth engagement does not have impact, idle stroke is shorter, can under any speed discrepancy, engage, use more extensive, its transmitting torque scope is from 1～100000Nm, but the roller in its structure is the elastic force by supported spring comes pushing tow, and its defective is complex structure not only, the dismounting trouble, and supported spring is long-term and the roller contact friction, cause fatigue or fracture easily, lose the effect of pushing tow roller, cause the clutch can't proper functioning and bring potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the defective of prior art and a kind of simple in structure, easy accessibility, safe and reliable free wheel device is provided.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of free wheel device, it comprises the dish shell, in the dish shell star-wheel that endoporus is a spline tooth is installed, and is provided with roller between the star-wheel ratchet, two end part between dish shell and the star-wheel are sealed by Oil sealing assembly, it is characterized in that being provided with in the described star-wheel ratchet magnetic post of close-fitting.
Compared with prior art, the utility model free wheel device replaces supported spring to hold roller with the magnetic post, situation long-term because of supported spring like this and that the roller contact friction causes fatigue or fracture to use easily just can not take place on the free wheel device that uses the magnetic post, and the free wheel device that uses the magnetic post is simple in structure, installation and removal are convenient, in use safe and reliable.
Description of drawings
Fig. 1 is the utility model broken section structural representation.
Fig. 2 removes structural representation behind the black box for the utility model.
Embodiment
To elaborate again to the utility model embodiment by above-mentioned accompanying drawing below.
As depicted in figs. 1 and 2, free wheel device is made of dish shell 1, star-wheel 2, roller 3, magnetic post 4, black box 5.
The dish shell is in the form of annular discs, and a plurality of attachment holes 8 are distributing on it.Being installed in the interior star-wheel of dish shell has the ratchet 6 of a plurality of circumference uniform distributions, by the cambered surface transition of tilting, makes and coil the trajectory of shell endoporus formation width between the adjacent ratchet, and its endoporus is a spline tooth 7, forms with splined shaft to be in transmission connection.Roller 3 is located in the trajectory of dish shell and star-wheel formation, is equipped with magnetic post 4 in each ratchet, and this magnetic post 4 is made by columniform magnet steel, and close-fitting can hold roller and make it eliminate bonding gap in narrow trajectory in the ratchet preprocessing hole.Black box 5 is made up of oil sealing, pad, jump ring, is located at the end between dish shell and the star-wheel, in the ratchet of star-wheel and roller are enclosed in.
When rotating power is imported and is rotated counterclockwise from coiling shell, driving roller by dish shell internal diameter makes it be rolled to narrow trajectory place, because narrow trajectory size less than the roller diameter, makes the roller chucking be held by the magnetic post again, star-wheel is promptly driven does constant speed rotation synchronously counterclockwise; As coil the shell input that runs out of steam that meets accident suddenly, but star-wheel also can be because of inertia be rotated further a period of time, and roller is brought to wide trajectory place, throws off fully with the dish shell, and star-wheel has produced and has surmounted rotation.This free wheel device is applied on the automobile can fully discharge inertia kinetic energy, and thoroughly eliminates reverse tractive force to motor and the injury of other machine members, reaches energy-saving effect.
