Description
Technical field
The utility model relates to the transmission system of vehicle, is specifically related to a kind of friction clutch being convenient to quick-replaceable friction plate.
Background technique
Friction clutch is become with operating mechanism four part group point by active part, secondary part, hold-down mechanism.Driving and driven part and hold-down mechanism ensure that clutch is in jointing state and the basic structure of energy transfer motion power, and the operating mechanism of clutch mainly makes the device of clutch separation.Its function has: ensure fork truck gentle start, ensure that fork truck is shifted gears smoothly and prevents driving mechanism overburdening.
Engine flywheel is the driving link of clutch, and driven disc and driven hub with friction plate borrow free-sliding spline to be connected with driven shaft (i.e. the driving shaft of speed changer).Driven disc is then pressed on flywheel end face by holddown spring.Namely engine torque passes on driven disc by the rubbing action between flywheel and driven disc surface of contact, then passes to driving wheel through driven shaft etc. thus.
When needs clutch separation, as long as step on the pedal in clutch operation, the shift fork be enclosed within the annular groove of clutch plate hub just promotes the pressure that driven disc overcomes holddown spring and moves to the direction of unclamping, and with divided flywheel from, frictional force disappears, thus has interrupted the transmission of power.
When needs recover transmission of power again, the speed that suitable solenoidoperated cluthes pedal gos up, makes driven disc under the effect of holddown spring pressure, moves resume contacts with flywheel to the direction engaged.Pressure between the two surface of contact increases gradually, and corresponding friction torque also increases gradually.When flywheel and driven disc engage also not tight, when friction torque is smaller therebetween, the two can asynchronously rotate, and namely clutch is in slipping state.Along with flywheel and driven disc engage the progressively increase of tightness degree, the two rotating speed is also gradually equal.Until when clutch engages completely and stops skidding, car speed can be directly proportional to engine speed.
In clutch's jointing process, one between driven member and driving link, is had not wait until from rotating speed the sliding wear process that rotating speed is equal, therefore also always with heating and the wearing and tearing of friction plate.Cause friction plate fragile, its life-span, generally at about 3 months, therefore needs to change continually.But because friction plate is connected with the driving shaft of clutch by spline, the driving shaft the other end also inserts in speed changer, therefore when repairing or replacing friction plate, need to take whole transmission system apart, taking out after driving shaft could more renewal of facing renewal, its workload is comparatively large, efficiency is low, and also needs a lot of instruments to operate.
Model utility content
The purpose of this utility model is exactly to solve above-mentioned Problems existing, provides a kind of friction clutch being convenient to quick-replaceable friction plate.
The technical solution of the utility model is: a kind of friction clutch being convenient to quick-replaceable friction plate, comprise driving shaft, one end of described driving shaft is connected with the friction plate being located at clutch inside, the other end is connected with the input gear being arranged in gearbox, the middle part of described driving shaft is fixedly arranged in bearing bracket stand, the centre of described bearing bracket stand is equipped with bolt, the screw rod of described bolt is connected with the other end casing of gearbox through after the casing of gearbox, bearing bracket stand successively, and the spiral shell head of bolt is positioned at the casing outside of gearbox; It is screw-thread fit between bolt and bearing bracket stand.
Further scheme, the middle part of described driving shaft is connected with bearing bracket stand by sheathed ball bearing thereon and collar, makes driving shaft consistent with bearing bracket stand axial motion; Described driving shaft and ball bearing, between ball bearing and bearing bracket stand, be interference fit.
Further scheme, described bolt is T-shaped bolt.
In the utility model, the driving shaft one end being arranged in gearbox is connected with input gear, and the other end is by ball bearing and bearing bracket stand interference fit, and on bearing bracket stand intermediate hole, screw-thread fit has a T-shaped bolt, and the spiral shell head of bolt is positioned at the outside of gearbox.When needing repairing or change clutch friction plate, transmission system is not needed to disassemble, precession is only needed to be positioned at T-shaped bolt on gearbox exterior edge face, bearing bracket stand is together moved, and drive the driving shaft that is applied in friction plate to move a segment distance together along with T-shaped bolt to transmission internal by bearing bracket stand, thus make driving shaft return gearbox inner chamber gradually and depart from friction plate, abdicate the space of more renewal of facing renewal, so just can take out the friction plate of wearing and tearing easily, new friction plate T-shaped bolt of counterrotating again after changing, new friction plate in driving shaft and clutch is coupled together.Thus the maintenance of friction plate or change convenient and swift, raise labour efficiency.Whole maintenance process needs a service worker just can complete in addition, and consuming time short and to relate to instrument few, assembly quality is stablized, and also can realize even if change at curstomer's site.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
In figure: 1-gearbox, 2-clutch, 3-input gear, 4-T type bolt, 5-bearing bracket stand, 6-ball bearing, 7-friction plate, 8-driving shaft.
Embodiment
As shown in Figure 1, a kind of friction clutch being convenient to quick-replaceable friction plate, comprise driving shaft 8, one end of described driving shaft 8 is connected with the friction plate 7 being located at clutch 2 inside, the other end is connected with the input gear 3 being arranged in gearbox 1, the middle part of described driving shaft 8 is fixedly arranged in bearing bracket stand 5, the centre of described bearing bracket stand 5 is equipped with T-shaped bolt 4, the screw rod of described T-shaped bolt 4 is connected with the other end casing of gearbox 1 through after the casing of gearbox 1, bearing bracket stand 5 successively, and the spiral shell head of T-shaped bolt 4 is positioned at the casing outside of gearbox 1; Be screw-thread fit between T-shaped bolt 4 and bearing bracket stand 5.
Further scheme, the middle part of described driving shaft 8 is connected with bearing bracket stand 5 by sheathed ball bearing 6 thereon and collar, makes driving shaft 8 consistent with bearing bracket stand 5 axial motion; Described driving shaft 8 and ball bearing 6, between ball bearing 6 and bearing bracket stand 5, be interference fit.
When keeping in repair or change clutch friction plate, precession is positioned at the T-shaped bolt on gearbox exterior edge face, bearing bracket stand is together moved, and drive the driving shaft be applied in friction plate together along with the rotation of T-shaped bolt moves a segment distance to transmission internal by bearing bracket stand, thus make driving shaft return gearbox inner chamber gradually and depart from friction plate, abdicate the space of more renewal of facing renewal, so just can take out the friction plate of wearing and tearing easily, new friction plate T-shaped bolt of counterrotating again after changing, makes the new friction plate in driving shaft and clutch couple together.
Above embodiment is not limited only to protection domain of the present utility model, all modify based on basic thought of the present utility model or change all belong to protection domain of the present utility model.
