Abstract
The invention discloses an integrated leaf spring type motorcycle overrunning clutch which comprises a body (5), a shield cover (4), a baffle (3) and pin rollers (2), wherein the pin rollers (2) are hollow cylinders; the middles of the pin rollers (2) are rolled to form ring grooves (2a); ribs (5a) which are integrally formed in wedge-shaped positioning grooves are embedded into the pin rollers (2); and an integrated leaf spring (1) is arranged between the adjacent two pin rollers (2) on the circumference and is pi-shaped. According to the overrunning clutch disclosed by the invention, the pin rollers are driven by the integrated leaf spring, so that the motion synchronism of each pin roller can be guaranteed, and the reliability of the performance of the overrunning clutch can be improved. Therefore, the overrunning clutch is relatively long in service life and has the characteristics of ingenious design, simplicity in transformation, and the like. Meanwhile, the hollow pin rollers are provided with guide structures, so that the production cost and weight are reduced, and the pin rollers are effectively prevented from being clamped.
Description
Technical field
The present invention relates to a kind of one-way element, specifically, the particularly integrated reed-type overdrive clutch of motorcycle of one.
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
It is simple, reliable that technical problem to be solved by this invention is to provide a kind of assembling, effectively can prevent the integrated reed-type overdrive clutch of motorcycle of clamping stagnation.
Technological scheme of the present invention is as follows: a kind of integrated reed-type overdrive clutch of motorcycle, 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), integrated form reed (1) is provided with between two circumferentially adjacent rollers (2), this integrated form reed (1) is " π " shape, by location piece (1a), first reed (1b) and the second reed (1c) composition, described location piece (1a) is arc, first reed (1b) is connected with location piece (1a) with the root of the second reed (1c), the root of described first reed (1b) and the second reed (1c) and location piece (1a) embed in the adaptive groove that on body (5) inwall, correspondence is offered, 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 present invention adopts integrated form reed to substitute stage clip and moves to drive roller, and integrated form reed is " π " shape, and moulding is simple, is easy to processing and fabricating; The location piece of integrated form reed and part first reed, the second reed insert in the adaptive groove of body vertically, easy for installation, quick, integrated form reed radial direction and circumference are positioned by location piece, axially by intrinsic step and baffle plate or guard shield spacing, integrated form 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.
Conveniently selection, is convenient to processing and fabricating, and reduce cost of production, and guarantee there is enough elastic force, described integrated form reed (1) is made up of spring steel sheet material.
The number of described roller (2) is 6-16.Because the assembling of integrated form 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 present invention drives roller by integrated form 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, have design ingenious, be easy to the features such as transformation.Meanwhile, adopt hollow rollers and be equipped with guide structure, both having reduced cost of production and weight, effectively prevent again roller generation clamping stagnation.
