Abstract
The utility model is a single direction and double direction controllable clutch. A shoe block[1], a main friction piece[11], a moving pressing board[15], a centrifuging ball[16] and a brake pushing board[17] are assembled on a shaft sleeve[5], which is mounted on an active plate[18], a slope mechanism [28] is positioned between the moving pressing board and the main friction piece, a circumferential resilient spring and an axial resilient spring are mounted respectively between the shaft sleeve and the active plate, and between a moving pushing board and the active plate. When the engine decelerates the speed, the shaft sleeve[5] looses the main and the following friction pieces and freely shifts the gear under the circumferential resilient spring action. When the vehicle decelerates the speed to contract the centrifuging ball to a half opening state, the moving pressing board moves backward under the axial resilient spring action, and looses the main and the following friction pieces, the engine continue to operate with an idle speed and the engine reaccelerates without the flameout.
Description
Technical field
The utility model relates to a kind of single-direction and dual-direction controllable clutch.
Background technique
At present the compressing tablet formula automatic clutch that uses of motorcycle by driving disc, driven disc, get rid of piece or centrifugal globe and master and slave wearing piece and form, when the motorcycle engine rotating speed reaches certain, get rid of piece or centrifugal globe and realize at action of centrifugal force lower compression wearing piece engaging.This degree of engagement strengthens with rotating speed, separate with the rotating speed reduction, its advantage is a clutch transmission efficiency height, its shortcoming is that clutch can only two-way clutch, clutch can not separate under the motorcycle high-speed travel state, and motorcycle can not neutral gear slides and switches gear, and all gear position operations can only carry out behind engine retard, not only operation inconvenience, and increase energy consumption.
Summary of the invention
To be solved in the utility model be must be first during the automatic clutch motorcycle is run at high speed the problem that just can shift gears after separating of speed-reducing clutch.
A kind of single-direction and dual-direction controllable clutch of the utility model comprises driving disc, driven disc, centrifugal globe and master and slave wearing piece; Master and slave wearing piece is separately fixed on the master and slave Moving plate; Centrifugal globe is fixed between driving disc and the main wearing piece by spring; It is characterized in that being equipped with on the driving disc axle sleeve, axle sleeve is axially fixed on the driving disc and can circumferential Returnning spring be housed between axle sleeve and the driving disc relative to rotating an angle with driving disc; Main wearing piece circumferentially is fixed on the axle sleeve, between centrifugal globe and the main wearing piece movable platen is arranged, the movable platen kink is on axle sleeve, movable platen has annular groove in the middle of centrifugal globe one side end face, between movable platen and the main wearing piece oblique mechanism that cooperatively interacts is arranged, this oblique mechanism segment distance of before engine start, spatially being separated by vertically, and in the angle that radially staggers mutually, the distance of movable platen reach when this axial distance equals centrifugal globe and moves to outermost end, this radial angle equals axle sleeve with respect to the counter-rotational angle of driving disc; Be fixed with axial Returnning spring between mobile push pedal and the driving disc; The front end of axle sleeve has a shoe block base to be fixed on the axle sleeve by ratchet mechanism, and the hoof piece is fixed on the shoe block base by bearing pin, and the interior circle that cooperates with the hoof piece is arranged on the driven disc.
Slow down in order when losing accelerator and brake, to drive driven disc by driving disc, drag effect behind the realization motor, the brake push pedal is housed between centrifugal globe and the driving disc, brake push pedal kink is on axle sleeve, there is the interlock push pedal in the driving disc outside, have pin-and-hole on the driving disc, the brake push pedal is fixed in the interlock push pedal by the pin-and-hole on the driving disc by bearing pin.In order to make brake steadily, between brake push pedal and the interlock push pedal damping spring is housed.
Have slideway and spring groove on the driving disc sidewall, Returnning spring and shifting block are housed in the spring groove, the axle sleeve rear end is provided with the slide block that cooperates with slideway, slide block on the axle sleeve extend out to the driving disc outside from slideway, the driving disc outside is provided with chuck, and chuck is fixed on the slide block, and shifting block one end in the spring groove is fixed on the chuck, when axle sleeve when rotating with driving disc, chuck drives shifting block and makes circumferential Returnning spring compression.
Bent axle drive driving disc and axle sleeve rotate together behind engine start, work as one regularly when rotating speed, and centrifugal globe opens under action of centrifugal force, and the inclined-plane promotion movable platen reach by movable platen makes the inclined-plane of movable platen and main wearing piece identical; At this moment, friction hoof piece also increases owing to rotating speed and opens fully, and with driven disc in contact and produce friction, thereby obtain reverse torsion and pass to axle sleeve by ratchet mechanism, the elastic force that makes axle sleeve overcome circumferential Returnning spring slides in the slideway of driving disc by slide block relative displacement takes place, movable platen and main wearing piece make master and slave wearing piece compress mutually by its oblique mechanism mutual extrusion, thereby inside and outside dish is engaged.
No matter how high engine speed is, when unclamping throttle, engine retard, because driving disc speed is lower than driven disc, hoof piece and shoe block base rotate with speed with driven disc owing to the effect of oppositely surmounting of ratchet mechanism, and axle sleeve resets under the effect of Returnning spring, makes master and slave wearing piece unclamp, this moment, motorcycle was in sliding state, and gear can freely switch.
When losing accelerator and brake, braking device promotes movable platen by driving mechanism and makes principal and subordinate's wearing piece compressive engagement, drives driven disc by driving disc and slows down, and drags effect behind the realization motor.When the speed of a motor vehicle is reduced to certain speed, centrifugal globe is contracted to half open configuration under the effect of elastic force, this moment, centrifugal globe was positioned at the middle groove middle part of movable platen, movable platen is axially separating with main wearing piece under the action of reset spring, master and slave wearing piece is unclamped, at this moment, engine idling operation and be unlikely to flame-out is so that quicken again.
Motor is when flame-out, centrifugal is in complete contraction state, as long as at this moment be with parking brake, braking device promotes movable platen by driving mechanism to be compressed principal and subordinate's wearing piece to make clutch be in jointing state, this moment is with riding starting bar, just rotatable driven gear also drives driven disc, ato unit.
Because the utility model separates master and slave wearing piece by overrunning clutch mechanism under fast state, thereby the operation that can freely slide and switch gear, realize one-way clutch, thereby overcome existing clutch operating inconvenience and the high shortcoming of energy consumption, transmission efficiency remains unchanged simultaneously.Drag effect after when motorcycle brakes under fast state there being motor, brake safe is reliable.
