Abstract
The utility model relates to a fully floating automatic centrifugal wedging wet fruction clutch, adopting the hoof-and-block cooperating full floating design, in which an active hub ledge slidingly fits with the circular arc-shaped internal groove in the hoof-and-block group and fits with the wedge surface. So a face-contact transmission force is formed between the top sheet of the clutch and the driven hub, the wedge surface of the hub ledge and the wedge surface of the hoof block male pin. And the resultant action of the wedging force of the two wedge surfaces is reasonably used to transfer the torsional moment. The utility model is characterized in that the transmission force is flexible, the binding is steady, the separation is thorough, the sliding is overrunning, the design is novel, the idea is peculiar, the structure is compact and the kinetic loss is low. The utility model is better than the similar products of the prior art and can be widely used in various gearing devices, particularly a lightweight automotive vehicles and power-assisted bicycles.
Description
The utility model relates to the automatic centrifugal wet friction clutch that a kind of transmission device is used, the automatic centrifugal wedging wet type friction clutch of particularly a kind of full floating.Can be widely used in the various transmission devices, especially on light automotive vehicles and the moped.
The centrifugal friction clutch of prior art is generally shoe plate centrifugal friction force transferring structure.Referring to accompanying drawing 2, one end of this kind centrifugal friction clutch shoe plate is with initiatively hub is hinged, the other end adopts spring and active hub to articulate, when the active hub reaches certain rotating speed, shoe plate overcomes spring tension and opens and combine output torque from the power hub under centrifugal action, its structural design is simple, easy to manufacture, its shortcoming is: shoe plate is that fulcrum opens with the fixing pin, effective junction plane deficiency in garden in shoe plate rubbing surface and the driven hub, and power transmission is inhomogeneous, transmission efficiency is lower, fixing pin is simultaneously as the fulcrum of transmitting torque, and is very high to its structural strength requirement, as easy as rolling off a log generation fracture and slippage in the practicality.Referring to accompanying drawing 3, this kind centrifugal friction clutch, the extension spring structure that has just changed aforementioned clutch is the stage clip structure, also fails fundamentally to overcome above-mentioned shortcoming.
The purpose of this utility model is to provide a kind of power transmission efficiency height at the above-mentioned shortcoming of existing centrifugal friction clutch, in conjunction with steady, and the automatic centrifugal wedging wet type friction clutch of the full floating of reliable performance.
The purpose of this utility model realizes in the following manner: it has a pair of centrifugal hoof block assembly, the interior circle of hoof piece cuts out an arc inside groove, at this groove middle part a radially pin-and-hole is arranged, the two end axles of hoof piece is installed an elastic cylindrical pin that articulates hoof piece spring to each, two hoof block assemblies articulate mutually with hoof piece spring respectively, hold tightly on active hub gabarit circumference, the middle riveting knot of hoof block assembly is installed the shoe pin nail of a band wedge surface, initiatively gabarit one side of hub cuts out two flanges, transmission direction one end design at flange has a wedge surface of radially cutting sth. askew with wheel hub, this wedge surface is corresponding with shoe pin nail wedge surface, when the active hub reaches certain rotating speed, hoof block assembly radial outward under centrifugal action is opened with the driven hub inner arc surface and is fitted fully, initiatively hub is given the hoof block assembly by flange wedge surface and shoe pin nail wedge surface transmitting torque, and the hoof block assembly applied the effect of wedge power, strengthen its combination force.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of existing extension spring centrifugal friction formula clutch.
Accompanying drawing 3 is existing stage clip centrifugal friction formula clutch configuration schematic representation.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Referring to accompanying drawing 1, structure of the present utility model is formed and is comprised hoof block assembly ［ 1 ］, active hub ［ 2 ］, hoof piece spring ［ 3 ］, elastic cylindrical pin ［ 4 ］, wet clutch dough sheet ［ 5 ］, shoe pin nail ［ 6 ］, this pin is two concentric circle cylinders, the design of great circle cylinder one side has a wedge surface of axially cutting sth. askew with pin, the roundlet cylinder is a rivet portion, in active hub cylindrical one side, design has two wide tooth flanges ［ 7 ］, one end-grain cutting of flange power transmission direction go out one with hub diameter initiatively to the wedge surface of cutting sth. askew, corresponding with shoe pin nail wedge surface, initiatively the hub middle part has the square hole ［ 8 ］ that connects with driving shaft, it connects with the stationary fit of driving shaft square face, hoof piece spring ［ 3 ］ is articulated on the elastic cylindrical pin ［ 4 ］ at the two ends of hoof block assembly, elastic cylindrical pin ［ 4 ］ expands knot in the axial key seat hole ［ 12 ］ at hoof piece two ends, wet clutch dough sheet ［ 5 ］ is bonded on the cylindrical of hoof block assembly ［ 1 ］, the interior circle of hoof block assembly ［ 4 ］ is cut the arc inside groove ［ 9 ］ chimeric movingly with active hub ［ 2 ］ flange together, middle design has radially key seat hole ［ 10 ］, and shoe pin nail ［ 6 ］ riveting knot is in radially key seat hole ［ 10 ］.When driving shaft rotates, drive initiatively hub rotation by the square hole ［ 8 ］ in the middle of the active hub, because effect of inertia, initiatively the protruding rafter wedge surface of hub is pressed to the wedge surface of shoe pin nail ［ 6 ］, thereby drive hoof block assembly ［ 1 ］ rotation, hoof block assembly ［ 1 ］ overcomes spring tension and radially opens under centrifugal action and under the thrust double action of flange wedge surface, the interior circle of pressing to driven hub ［ 11 ］ is realized the friction power transmission.Along with the increasing of rotating speed, centrifugal action is strengthened, and hoof block assembly ［ 1 ］ is progressively strengthened with driven hub applying degree, and carry-over moment smoothly rises.Because the hoof block assembly floats and articulates, the clutch surface outer arc is evenly to press to circle in the driven hub, thereby has guaranteed face contact power transmission, realizes steady combination.Simultaneously, under the wedge power effect of active hub flange wedge surface, hoof block assembly ［ 1 ］ is played the pressure supporting effect, strengthened the applying effect of hoof block assembly ［ 1 ］ and clutch surface ［ 5 ］ and driven hub ［ 2 ］, improved the moment of torsion transmission efficiency.When driving shaft slows down, as the increase overload of loading, the centrifugal force of hoof block assembly ［ 1 ］ reduces, and under hoof piece spring ［ 3 ］ pulling force, shoe pin nail ［ 6 ］ moves down along the flange wedge surface, clutch surface ［ 5 ］ descends with the interior circle of driven hub ［ 11 ］ applying degree, occur trackslipping relatively,, justify in clutch surface ［ 5 ］ and the driven hub ［ 10 ］ and separate when the centrifugal force of hoof block assembly ［ 1 ］ pulling force less than hoof piece spring ［ 3 ］, power is cut, realizes sliding fully.Elastic cylindrical pin ［ 4 ］ is selected for use the 65Mn material to be shaped to expand through heat treatment and is tied at the two ends of hoof block assembly ［ 1 ］, and it is easy to wear to have overcome common solid pin, the shortcoming of fracture and slippage.The utility model design is unique, modern design, compact structure.Between clutch surface ［ 5 ］ and driven hub ［ 11 ］, shoe pin is followed closely between ［ 6 ］ wedge surface and active hub ［ 2 ］ the flange wedge surface, has adopted the face contact stressed, has and uses reliably, and in conjunction with steady, separation thoroughly surmounts the characteristics of trackslipping.Power transmission effect and operating reliability are better than existing like product, can be widely used in the various transmission devices especially on the light automotive vehicles and moped.
