Abstract
The invention discloses a separation type double-clutch transmission, belongs to a transmission for a front transverse engine, and is a dry three-shaft double-clutch transmission. Double dry clutches are separately arranged at two ends of the transmission; and the dry three-shaft double-clutch transmission has a similar single-clutch structure and control mode compared with a manual transmission, is simpler in structure and more reliable in work compared with a double-clutch set of a traditional dry double-clutch transmission, retains the advantages of quick and smooth gear shifting of the double-clutch transmission, and only slightly increases the size.
Description
Technical field
The present invention relates to a kind of dry dual clutch, it is a kind of dry type three axle double-clutch speed changer, be applicable to transverse engine passenger car, specifically provide a kind of separated type double-clutch speed changer and adopt two dry clutches (13), (24), input shaft is by input solid shaft (15) and be enclosed within its outer two sections of hollow shafts (16), (21) and form, two dry types from
Close device (13), the Placement of (24), control mode, the working method of synchromesh unit (20).
Background technique
Current dry dual clutch is widely used in passenger car, has that transmission efficiency is high, the smooth-going advantage fast of gear shift, but also there is the double clutch group complex structure problem that easily overheated, reliability is low.
Summary of the invention
The object of this invention is to provide a kind of novel dry type separated type double-clutch speed changer, existing dry dual clutch transmission efficiency be high, the smooth-going advantage fast of gear shift, have again the advantage that manual single clutch structure is simple, reliability is high.
The technical solution adopted for the present invention to solve the technical problems is: abandon the double clutch group that current dry dual clutch is arranged in input end, by two dry clutches (13), (24) replace, be arranged in transmission input and the other end relative with input end, two dry clutches (13) of separated type, (24) by the two ends of input solid shaft (15) and the even number shelves hollow shaft (16) be enclosed within outside it, odd number shelves hollow shaft (21) is connected, carry out clutch for clutch control, gear on even number shelves hollow shaft (16) often engages with the upper even number shelves gear of two output shafts (11), gear on odd number shelves hollow shaft (21) often engages with the odd number shelves gear on two output shafts (11).
Two dry clutches (13) of the present invention, (24) clutch for clutch control is by release bearing (14), (23) to push away or membrane flat spring completes, release bearing (14), (23) axial displacement is controlled by fork or hydraulic piston, adopt the release bearing (14) of Push control mode, (23) only just diaphragm spring is promoted when gear shift, make dry clutch (13), (24) platen is separated or semi-linkage with clutch friction plate, then diaphragm spring is departed from the end of gearshift, make dry clutch (13), (24) platen and clutch grind sassafras sheet and keep jointing state, now only has an engage a gear in four synchromesh units (20), another three then keep neutral gear, separated type double-clutch speed changer is by the way to dry clutch (13), and the control of synchromesh unit (20) (24), decrease release bearing (14), (23) operating time, add dry clutch (13), (24) engaging time.
Two dry clutches (13) of the present invention, (24) solid shaft (15) two ends and two sections of hollow shafts (16) will be inputted, (21) mode connected is: the engine flywheel (12) be connected with separated type double-clutch speed changer can be single mass flywheel or double mass flywheel, when adopting single mass flywheel, dry clutch (13) outer cover being positioned at separated type double-clutch speed changer input end is fixed by bolts on engine flywheel (12), engine flywheel (12) is fixed by bolts on engine crankshaft flange plate (25), the spring torsional vibration damper (26) be positioned on engine flywheel (12) is used for vibration damping, with input solid shaft (15) one end shaft coupling, spring cushion (26) center be used for shaft coupling shaft coupling output shaft (27) external splines with input solid shaft (15) port internal spline be connected, when adopting double mass flywheel, can spring torsional vibration damper (26) be fixed in the secondary flywheel mass of double mass flywheel, the clutch friction plate of dry clutch (13) is enclosed within the external splines of hollow shaft (16) one end by band internal spline hollow hub, the dry clutch (24) being positioned at separated type double-clutch speed changer input end opposite can be adopted and will be inputted solid shaft (15) one end and be enclosed within input solid shaft (15) hollow shaft outward (21) one end and be connected in two ways, dry clutch (24) outer cover is fixed on hollow shaft (21) one end by a kind of mode, the clutch of dry clutch (24) the sassafras sheet that rubs is enclosed within the male splined shaft of input solid shaft (15) one end by band internal spline hollow hub, dry clutch (24) outer cover is fixed on input solid shaft (15) one end by another kind of mode, the clutch friction plate of dry clutch (24) is enclosed within the male splined shaft of hollow shaft (21) one end by band Inner spline hollow hub.
Owing to adopting such scheme, power transfer path of the present invention starts to be divided into two-way after flowing through engine flywheel (12), one tunnel is through dry clutch (13), one dual numbers shelves gear, a pair output gear (10) (19) or (18) (19) arrive differential mechanism final gear (19), another road is through input solid shaft (15), dry clutch (24), a pair odd number shelves gear, a pair output gear (10) (19) or (18) (19) arrive differential mechanism final gear (19), visible two-way power transfer path of the present invention is independently, be equivalent to odd number shelves, even number shelves manual transmission is in parallel, so it is simple to have manual transmission structure, the characteristic of reliable operation, and the two clutch group of the dry type of current dry dual clutch must undertake clutch and the shunting of two-way power, be difficult to avoid complex structure, the shortcoming that reliability is low.
