Abstract
The invention provides a gear type self-adjusting clutch which comprises a gland, a membrane and a pressing disc, wherein an annular groove is arranged on the surface of the pressing disc, and a plurality of slopes are arranged in the annular groove; an adjusting ring is arranged in the annular groove, one surface of the adjusting ring is machined to form a plurality of slopes, and the other surface of the adjusting ring is machined to form a bearing rib; the highest point of the slopes of the adjusting ring and the lowest point of the slopes on the annular groove are fastened together; an arc-shaped driving gear rack is fixed in a plane inside the pressing disc, an adjustment driving assembly is arranged at the inner side of the adjusting ring, which is opposite to positions of teeth of the arc-shaped driving gear rack, and the teeth of the arc-shaped driving gear rack are meshed with a gear of the adjustment driving assembly; and the gland is riveted with the membrane through a limit rivet. The gear type self-adjusting clutch has the advantages of stability in operation and convenience and quickness for assembly; and the gland and the pressing disc assembly can be reused by only disassembling the gland to reset the adjusting ring, and the adjusting ring can be reset very conveniently and quickly.
Description
(1) technical field: the present invention relates to be used for automobile clutch, specifically is a kind of gear type self-regulating clutch.
(2) prior art: the normal film lamella clutch in use, when from total friction disc wear to the diaphragm peak, its Separating force is bigger more than 30% than the Separating force of original state, that have even reach 50%, separating mechanism to car load causes very big influence like this, to when always may wear to the design limit position, its impacting force is parabolic shape and changes normal film lamella clutch work impacting force from original state.Make Separating force distinguish bigger like this at original state and the state after total wearing and tearing.Separating force after the wearing and tearing generally can be than the big 20%-30% of original state, and clutch pedal can produce to send out and sink.So not only bring very big inconvenience to driver operation, and very big to the control system influence of clutch.Master cylinder in the booster in the clutch operating system, wheel cylinder are also because of variation considerable influence working life of Separating force.
Normal film lamella clutch assembly presses total points to change from referring to that highly meeting is constantly gone up behind total friction disc wear in addition, and promptly the jointing altitude of clutch uprises.Just need to adjust release bearing and the distance of pressing total diaphragm to separate finger tip this moment.Bring some inconvenience to the user.Also can cause release bearing to lose efficacy easily if forgotten to adjust, clutch assembly failure conditions such as skid.
(3) summary of the invention: purpose of the present invention is improved existing clutch configuration exactly.Propose a kind of clutch working stability in the using process of whole design service life, it is convenient to assemble, and does not have vehicle from the device of return for release bearing, need not often adjust the gear type self-regulating clutch in release bearing gap.
Gear type self-regulating clutch of the present invention comprises gland, diaphragm and platen, is processed with a circular groove on the platen card, it is characterized in that: be processed with several inclined-planes in the described circular groove; Be placed with one and adjust ring in circular groove, this adjustment ring one side is processed into some inclined-planes, and another side is processed into bearing rib; Adjusting the inclined-plane peak of ring and the inclined-plane minimum point on the circular groove snaps together mutually; Be fixed with arc driving tooth bar at the platen inner plane, the adjustment ring installed inside that drives the tooth mouth position of tooth bar with respect to arc has the driving of adjustment assembly, and the tooth mouth that arc drives tooth bar is meshed with the gear that adjustment drives assembly; Gland and diaphragm are riveted by spacing rivet.
Gear type self-regulating clutch, it is characterized in that: described adjustment drives assembly and comprises bearing, driving spring sheet, drives wheels, holddown spring, described bearing upper end is provided with opening slot, the lower end is provided with a U type groove, described driving spring sheet one end riveting is at rest base, and the other end is stuck in the bearing opening slot; Described driving wheels are made of ratchet and actuation gear and holddown spring, and holddown spring is installed on the ratchet shaft, drive the wheels riveting and are contained in the U type groove of bearing.
Gear type self-regulating clutch is characterized in that: described spacing rivet position is in diaphragm waist shaped hole place.
Gear type self-regulating clutch is characterized in that: be evenly equipped with some spacing rivet holes on the gland.
Working principle: when the clutch drived disk assy friction plate uses the back wearing and tearing, press total platen to move down, the diaphragm height also can change thereupon, when diaphragm spring is displaced to the certain position degree, pressing the driving spring sheet, the driving spring sheet is stirred ratchet, driven gear, and adjusting driving mechanism on platen is two bodies; The one, the adjustment of band driving spring sheet, driving wheels and bearing drives assembly, is installed in the adjustment ring inboard on band inclined-plane, adjusts ring and is supporting diaphragm spring.The 2nd, arc drives tooth bar, is installed on platen inner plane two mounting holes.Adjusting the gear that drives in the assembly meshes with the tooth mouth that arc drives tooth bar.When ratchet gear rotates, will drive and adjust ring and rotate, make the working position of diaphragm spring of clutch remain unchanged substantially like this.
The present invention has following characteristics:
Working stability, self-regulating clutch in use can make the position, operation point keep constant relatively by adjusting ring and relevant regulating mechanism.Separating force changes not quite like this, and is very little to the control system influence.After having avoided clutch to use a period of time, clutch frequency of utilization height on the phenomenon that clutch pedal is sent out heavy, the especially passenger vehicle just requires the stable of clutch separation characteristic, and fine this type of problem that solved of self-regulating clutch.
It is convenient to assemble, because the self-regulating clutch all is to be in the initialization state position and anti-loosening bolt is housed before dispatching from the factory, or diaphragm and gland are riveted together.Assembly is very laborsaving when the entrucking construction bolt, also improves installation efficiency.It is highly specialized that part is made and assembled.But to pull down anti-loosening bolt after noting installing clutch.Not so clutch can not effectively be worked.
In control system, release bearing not from returning device need not often adjust the release bearing gap, ordinary clutch will be adjusted free pedal travel (being release bearing and the gap of separating between the finger) in use for some time.If the user is unfamiliar with or in time do not adjust its gap, can cause the release bearing premature failure, reach bad phenomenon such as cltuch slipping.And the jointing altitude of self-regulating clutch is constant relatively, does not need to ask frequent adjustment operating mechanism.It is very big convenient to bring to the user.
Long service life in the time will changing driven disc, only needs the total gland of pressures is opened, will adjust encircle the placement initial position after, load onto gland and just can reuse.
Installation step of the present invention is as follows:
The driving spring sheet is riveted on the bearing, in the U of bearing type groove, debugs the whole wheels that drive again, also carry out the riveting dress, form adjustment and drive assembly; In platen inner plane two mounting holes, load onto arc and drive tooth bar; The adjustment that assembles is driven assembly be installed on two mounting holes of adjustment ring, be placed in the manufactured circular groove.Adjusting the inclined-plane peak of ring and the inclined-plane minimum point on the circular groove snaps together mutually; After placing supporting ring, diaphragm in the gland with the good driver blade of riveting, the spacing rivet of riveting over; Gland riveting dress is finished and platen assembles the back and close, and assembles four assembly bolts.
