Description
Technical field
The present invention relates to a kind of one-way element, specifically, the particularly axial plug-in type overdrive clutch of motorcycle of a kind of reed.
Background technique
Free wheel device is the basic part occurred along with the development of electromechanical integrated product, and it is the vitals for transmission of power and separation function between prime mover and working machine or between machine intimate driving shaft and driven shaft.The major function of free wheel device is: surmount or transmitting torque, accurately locate, prevent reverse.
Existing overdrive clutch of motorcycle is generally made up of body, guard shield, baffle plate, roller and stage clip.Roller is arranged in the wedge shape locating slot that inner body wall is offered, in wedge shape locating slot, be also provided with stage clip, and a corresponding roller of stage clip, stage clip drives roller to move in wedge shape locating slot.Because stage clip needs processing skewed slot in addition to install, the difficulty of processing of stage clip installation skewed slot is large on the one hand, can increase cost of production; On the other hand, stage clip assembling difficulty, easily produces crooked, causes stage clip clamping stagnation, fracture, thus affect reliability and the working life of free wheel device.
In addition, although roller is by guard shield and baffle plate axial limiting, has gap between roller and guard shield and baffle plate, can produce crooked when such roller moves in wedge shape locating slot unavoidably, also easily cause clamping stagnation thus, thus affect the usability of free wheel device; Roller is generally solid cylinder, and not only cost of material is higher, and can increase the weight of free wheel device when roller number is more.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of and assembles simple, good reliability, effectively can prevent the axial plug-in type overdrive clutch of motorcycle of the reed of clamping stagnation.
Technological scheme of the present invention is as follows: the axial plug-in type overdrive clutch of motorcycle of a kind of reed, comprise body (5), guard shield (4), baffle plate (3) and roller (2), in the side of described body (5), guard shield (4) is installed, opposite side installs baffle plate (3), the inwall of body (5) is provided with circumferentially equally distributed wedge shape locating slot, roller (2) is all housed in each wedge shape locating slot, it is characterized in that: described roller (2) is hollow cylinder, annular groove (2a) is formed with by roll extrusion at the middle part of roller (2), the fin (5a) be integrally formed in wedge shape locating slot embeds in this annular groove (2a), elastic drive part is provided with between two circumferentially adjacent rollers (2), this elastic drive part is circumferentially uniformly distributed, described elastic drive part has the reed (1) of two pieces of distributions in "eight" shape, described reed (1) is made up of waveform section (1a), roundabout section (1b) and straight section (1c), waveform section (1a) is connected with straight section (1c) by roundabout section (1b), and the waveform section (1a) of each reed (1) is inserted in the adaptive groove that on body (5) inwall, correspondence is offered vertically, the straight section (1c) of elastic drive part wherein one piece of reed (1) abuts with circumferentially previous roller (2), and the straight section (1c) of another block reed (1) abuts with a circumferentially rear roller (2).
Adopt above technological scheme, roller is hollow cylinder, while not affecting performance, both reduces cost of material, alleviates again overall weight.Fin extends along the length direction of wedge shape locating slot, fin and groove fit, plays guiding, can not occur crooked, thus effectively eliminate the disadvantage of clamping stagnation when roller is moved in wedge shape locating slot.
The present invention adopts the elastic drive part of one group of reed composition to substitute stage clip and move to drive roller, and reed is made up of waveform section, roundabout section and straight section, and moulding simply, is easy to processing and fabricating; The waveform section of reed is inserted in the adaptive groove of body vertically, easy for installation, quick, and reed radial direction is located by waveform section, axially by baffle plate and guard shield spacing, reed location is reliable, can not occur to loosen or come off.Straight section with piece reed of two in group abuts with circumferentially former and later two rollers all the time, promote roller by the tension force between two reeds to move in wedge shape locating slot, so circumferentially the synchronism of each roller motion is good, and free wheel device reliable performance, working life is secure.By roundabout section of transition between the straight section of reed and waveform section, under the effect of roundabout section, straight section has enough elastic force, roller is moved faster.
Conveniently selection, is convenient to processing and fabricating, and reduce cost of production, and guarantee there is enough elastic force, described reed (1) is made up of spring steel.
As preferably, the number of described roller (2) is 6-16.Because reed assembling is simple, arranges easily, such body can be arranged the roller of greater number, effectively to improve bearing capacity.
Conveniently processing and fabricating, reduces cost of production, and prevents wearing and tearing, and described roller (2) rolls sealing by the steel disc that 0.8-2mm is thick and forms.
In order to ensure structural strength, prevent to damage, described fin (5a) diminishes from root gradually toward most advanced and sophisticated direction.
Beneficial effect: the present invention forms elastic drive part to drive roller by the reed of two pieces of axial plug-in mountings, compact structure, processing and assembling easily, low, the reed axis of cost of production and radial location good, the synchronism that each roller moves can not only be ensured, and the reliability of free wheel device performance can be improved, make the longer service life of free wheel device.Meanwhile, adopt hollow rollers to be also equipped with guide structure, both reduced cost of production and weight, effectively prevent again roller generation clamping stagnation, have that design is ingenious, structure simple, transform the features such as easy.
