Description
Technical field
The utility model relates to a kind of one-way element, specifically, and particularly a kind of composite spring chip motorcycle one-way overrunning clutch.
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.
Model utility content
The composite spring chip motorcycle one-way overrunning clutch that technical problem to be solved in the utility model is to provide a kind of good reliability, effectively can prevents clamping stagnation.
The technical solution of the utility model is as follows: a kind of composite spring chip motorcycle one-way overrunning clutch, 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), combined type reed (1) is provided with between two circumferentially adjacent rollers (2), this combined type reed (1) is by cylindrical body (1a), first reed (1b) and the second reed (1c) composition, described cylindrical body (1a) inserts in body (5) the adaptive groove that above correspondence is offered vertically, and by the closing in of adaptive groove, baffle plate (3) and guard shield (4) jointly spacing, described first reed (1b) is fixed (1a) with the root of the second reed (1c) and is connected with cylindrical body, there is between first reed (1b) and the second reed (1c) angle of 20-30 °, described first reed (1b) abuts with circumferentially previous roller (2), second reed (1c) 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 utility model adopts combined type reed to substitute stage clip and moves to drive roller, and the moulding of combined type reed is simple, is easy to processing and fabricating; The cylindrical body of combined type reed inserts in the adaptive groove of body vertically, easy for installation, quick, and the radial and circumference of combined type reed is positioned by cylindrical body, axially by baffle plate and guard shield spacing, combined type reed location is reliable, can not occur to loosen or come off.Two pieces of reeds abut with circumferentially former and later two rollers all the time, and promote roller by the tension force between two reeds and 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.
The number of described roller (2) is 6-16.Because the assembling of combined type reed 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 utility model drives roller by combined type reed, compact structure, processing and assembling are easily, cost of production is low, reed location is 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.
