Abstract

The utility model relates to a dry-type double-clutch device, which aims at an existing dry-type clutch device which adopts two clutch device pressure disks, and leads double clutches to respectively combine and disconnect through respectively controlling the two pressure disks to press and loosen, and has complex structure and high requirement to separating and combining control precision. The utility model adopts a single pressure disk in structure, and the single pressure disk is arranged between two driven disks. When the pressure disk is moved to lead the clutch to combine, the other clutch must be disconnected, and when a clutch is thoroughly separated, the other clutch can be combined, thereby avoiding that working of two clutches are overlapped in structure, and leading the control of the clutch to be simplified. The dry-type double-clutch device reduces the amounts of component parts, lightens weight, improves the control reliability, and lowers production cost.

Description

Single platen dry friction formula double clutch

Technical field

The utility model relates to the mechanical power transmission system.

Background technique

Along with the development of mechanical power transmission technology, dual clutch transmission arises at the historic moment, and is characterized in that Transmission gear arranges by two power input shafts respectively by odevity.These two power input shafts are generally axle sleeve shaft type coaxial configuration, and promptly an input shaft pipe box is on another root input shaft.Two input shafts pass through splined with two clutch driven plates respectively.Combine with two driven discs respectively by clutch compressing disc and to compress, the power that prime mover transmission is come is respectively by two transmission input shaft transmission.Because adopt two transmission input shafts can arrange the odevity gear respectively, so when a transmission input shaft transferring power, the just gear shift on request of another root transmission input shaft.When needs during with this gear transferring power, clutch will be in conjunction with this transmission input shaft.Can reduce transmission of power break period like this, improve the power utilization of machinery etc.

Present dry friction formula double clutch adopts two clutch compressing discs, by controlling compressing with unclamping of two platens respectively clutch is combined and disconnection, as U. S. Patent: 20060021842, European patent: EP1748206A2, Chinese patent: 200610156251.4,200710300333.6, be not always the case.Its structure is complicated.In speed variator shift process, do not interrupt for making power, two clutches are controlled respectively.Will there be two clutch work overlapping phenomenons in its result, if control badly, the two is overlapping excessive, then the gear interference phenomenon can occur, and gear is stuck when serious, engine misses, and clutch is ablated, even badly damaged clutch and speed changer.Therefore existing double clutch to clutch also very high in conjunction with the separating controlling required precision.

Summary of the invention

For solving the overlapping and too high problem of control accuracy of work of two clutches in the existing double clutch, the utility model adopts single platen structure, is located between two driven discs in the double clutch.When control platen make a clutch in conjunction with the time, another clutch must disconnect; When a clutch thoroughly separates, another clutch just may in conjunction with.Thereby structurally avoided two overlapping troubles of bringing of clutch work in the double clutch, and made the simple and compact for structure of clutch, control is simplified.The double clutch number of spare parts is reduced, weight saving, control reliability improves, and cost reduces.

Embodiment

Below in conjunction with accompanying drawing, scheme is described further.

As first embodiment, in basic scheme shown in Figure 1, flywheel 4 is rigidly connected with engine crankshaft 3, and lid 7 is rigidly connected with flywheel, and platen 8 is between driven disc 9 that has the both surface friction sheet and driven disc 14.Platen links to each other with lid, and is arranged between two driven discs by driver blade 24, support plate 25, support ring 26.When certain responsive to axial force was on platen, driver blade produced the axial elasticity distortion, and platen covers relatively and moves axially.Platen link press span 10 is rigidly connected with platen, and lever dish 12 is with to be rigidly attached to the support 13 that covers hinged.Driven disc 9 is connected with speed changer first input shaft 20 keys by driven disc splined hub 22, driven disc 14 is connected with speed changer second input shaft 19 keys by driven disc splined hub 21, for turning round steadily, lid is supported on speed changer second input shaft by lid support 15, bearing 18.During engine operation, engine crankshaft, flywheel, lid, lid support, platen, platen link press span, lever dish etc. are wraparound shaft axis coaxial rotation together.Respectively when the lever dish application of force, the lever dish drives platen by the platen link press span and moves axially and compress driven disc by release bearing 16,17, and power is exported by driven disc.When by release bearing 17 when the lever dish applies left power, then platen moves to right, with the increase of putting forth effort with displacement, platen compresses driven disc 14, by the splined hub on the driven disc 14 21, transmits power on speed changer second input shaft.When by release bearing 16 when the lever dish applies to the right power, then platen moves to left, with the increase of putting forth effort with displacement, platen compresses driven disc 9, by the splined hub on the driven disc 9 22, transmits power on speed changer first input shaft.When platen mediates, be power no-output state.

Owing to adopted single platen in double clutch, institute is so that the designs simplification of double clutch, and number of spare parts reduces, and Clutch Control is easier, the cost reduction.

As second embodiment, flywheel is a double mass flywheel.As everyone knows, double mass flywheel is that the flywheel main body is made up of active mass and driven quality, is provided with between the two and reverses damping spring.As shown in Figure 2.

As the 3rd embodiment, flywheel is a double mass flywheel, and driven disc does not have the driven disc spring.

As the 4th embodiment, as shown in Figure 3, lid support and lid are made of one, and initiatively encircle 23 and are rigidly attached to and cover.

As the 5th embodiment, very compact and guarantee cover rigidity when enough when structural design in basic scheme shown in Figure 1, cancel lid support 15 and bearing 18, initiatively encircle 23 and be rigidly attached to and cover.Further reduce number of spare parts, reduce cost.As shown in Figure 4.

As the 6th embodiment, platen makes hollow ventilation and heat structure.
