Abstract
The utility model relates to a two-way forced friction overdrive clutch, which belongs to the clutch type. The clutch of the utility model is composed of a circular disc, a cam, friction hoof blocks, friction sleeves, and springs, wherein, the cam is arranged on a drive shaft; the upper space of the shaft shoulder of the cam is sheathed with the circular disc; the circular disc is provided with a pin shaft; at least more than two friction hoof blocks are penetrated through the pin shaft; the springs are arranged on the pin shaft and the friction hoof blocks; the friction sleeves are connected with a driven shaft, and are sheathed on the outer edge of the friction hoof blocks. The utility model has the advantages of simple structure, good manufacturability, smooth combination, no impact, no friction, and long service life.
Description
The utility model relates to a kind of double rolling key clutch, belongs to clutch.
Chinese patent application number is 93237600.2 and is called that the patent of " the two-way pawl formula free wheel device that flies " has realized positive and negative two to driving driven shaft and purposes that can bidirectional overtaking, but fly pawl in conjunction with the time greater impact noise arranged, impact force is higher to the material and the heat treatment requirements that fly pawl and gear ring, causes cost higher.
The purpose of this utility model is to propose that a kind of structure is more simple, anufacturability is better, in conjunction with the smooth-going forced friction formula double rolling key clutch that does not have impact noise again.
The utility model is made up of garden dish, cam, friction hoof piece, friction sleeve, spring, cam is installed on driving shaft, the garden dish is being overlapped in the shaft shoulder sky of cam, on the dish of garden, bearing pin is arranged, at least plural friction hoof piece is through on the bearing pin, spring is contained on bearing pin and the friction hoof piece, make between friction hoof piece and the friction sleeve and keep certain interval, friction sleeve is enclosed within friction hoof piece outer ring and connects outputting power with driven shaft, this clutch is if be used for the electric starting device of motorcycle, and then the friction sleeve magnetogenerator that should be riveted on engine crankshaft puts outward.
Illustrate that accompanying drawing is as follows:
Fig. 1 is a structural representation of the present utility model; (state of rest)
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the shaft side figure of Fig. 1;
Fig. 4 is the working state schematic representation of Fig. 1;
Fig. 5 is the structural representation of the two hoof asymmetrics of the utility model;

Fig. 7 is the shaft side figure of Fig. 5;
Fig. 8 is the working state schematic representation of Fig. 5;
Fig. 9 is the structural representation of the utility model three hoof arc triangle edge cam.
Accompanying drawings embodiment is as follows:
Cam (2) is housed on the driving shaft (sees Fig. 1,2), the shaft shoulder sky of cam (2) is being overlapped and is being had bearing pin (8,9) garden dish (1), friction hoof piece (4) is contained on the bearing pin (8), with garden dish (1) coaxial line friction sleeve (7) is installed, friction sleeve (7) is connected with driven shaft, spring (5) is a torsion spring, and an end is enclosed within on the bearing pin (8) on the garden dish (1), and its jag end is inserted in bearing pin (9) and the bearing pin (10) on friction hoof piece (4) on the garden dish (1).Spring (5) makes between friction hoof piece (4) and the friction sleeve (7) and keeps certain clearance.Friction hoof piece (4) is stained with asbestos friction sheet on the outer garden, and its outer garden is made up of the garden arc of two groups of decentraction.Friction hoof piece (4) is gone up iron chains rotary ball (3), makes clutch operating more flexible.
When driving shaft clockwise or when rotating counterclockwise, cam (2) rotates immediately, garden dish (1) quality is slower because of the effect of inertia starting more greatly, cam (2) can be propped up friction hoof piece (4) with relatively rotating of garden dish (1) and make it to begin to contact with friction sleeve (7), the motion that friction hoof piece (4) and friction sleeve (7) coil because of the frictional force obstruction garden that contact formation, this just makes cam (2) the hoof piece (4) that will rub prop up more, frictional force strengthens with the raising of positive pressure, drags friction sleeve (7) and the common rotation of garden dish (1) the most at last.When output speed during greater than driving shaft, the moment that ball (3) on the friction hoof piece (4) and cam (2) disengage, frictional force will disappear because of the disappearance of positive pressure, and spring (5) makes friction hoof piece (4) once again away from friction sleeve (7), has realized the performance that driving shaft is surmounted.
Cam (11) is housed on the driving shaft (sees Fig. 5,6), the disk (13) that has bearing pin (12) is being overlapped in the shaft shoulder sky of cam (11), and friction hoof piece (14) is enclosed within on the bearing pin (12), and, make it to be positioned on the basic circle of cam (11) with extension spring (15) tension mutually.Friction sleeve (16) is connected with driven shaft, is sleeved on the cylindrical of friction hoof piece (14).Be stained with asbestos friction sheet on the cylindrical of friction hoof piece (14), iron chains have ball (17) on its inner plane.The tightening force of extension spring (15) should be slightly larger than the centrifugal force under friction hoof piece (14) working state.
Arc triangle edge cam (18) (see figure 9) is housed on the driving shaft, overlapping the disk (20) that has bearing pin (19) in the shaft shoulder sky of cam (18), friction hoof piece (21) is enclosed within on the bearing pin (19), and with mutually tension of extension spring (22), make it to be positioned on the basic circle of cam (18), friction sleeve (23) is connected with driven, is sleeved on the cylindrical of friction hoof piece (21), be stained with asbestos friction sheet on the cylindrical of friction hoof piece (21), iron chains have ball (24) on its inner plane.The tightening force of extension spring (22) should be slightly larger than the centrifugal force under friction hoof piece (21) working state.
Clutch configuration of the present utility model is simple, and anufacturability is good, in conjunction with smooth-going, do not have and impacts, no abrasion, long service life.
