Description
Technical field
The present invention relates to the double-clutch speed changer in a kind of Motor Vehicle, have two sub-speed changers, described sub-speed changer respectively has a transmission input shaft, and described transmission input shaft can be coupled with the live axle of driver element by a friction clutch respectively.
Background technique
Double-clutch speed changer uses known by the series connection in power train.This double-clutch speed changer comprises two sub-speed changers, sub-speed changer respectively have a transmission input shaft and have a common transmission output shaft and a plurality of in correspondence transmission input shaft and this transmission output shaft between convertible, shelves with different gear ratio.By alternately by the gear ratio of sub-speed changer classification, can realize the load shift ground operation of double-clutch speed changer, its mode is, the friction clutch of another sub-speed changer is opened in the situation that the friction clutch of a sub-speed changer is closed, when each extension files, in order to implement gear shift, change respectively friction clutch only overlappingly.All open in situation at two friction clutches, by make have hang into the friction clutch closure of start gear realize starting.At this, negative gradient and/or other impact of the friction factor of the friction pair of, friction clutch insufficient with respect to the geometrical arrangements of clutch pressure plate, insufficient on the operation that friction clutch carries out by clutch actuator due to the clutch disk of relevant friction clutch, when friction clutch skids especially during starting process, when friction clutch is re-engaged and under analogue, clutch may occur and buffet (Kupplungs-rupfen), this clutch is buffeted and is made the driver and other passengers are felt under the weather.At this, excite outside in the buffeting situation, moment modulation appears on friction clutch, and this moment causes jumping up when being modulated at resonance and causes therefore that the driver is appreciable, the vibration on direction of travel.In autoexcitation buffeting situation, introduce negative damping by the negative friction coefficient gradients that friction serves as a contrast, the integral damping of the vibration system of this degree of this negative damping ground dehancer speed changer, make and evoke almost not jumping up of vibration damping in the minimum situation of system change, this is jumped up and causes the appreciable vibration of driver.In addition, in power train, other noise may appear, as gear shift clickly sound or similar sound.
Buffet and other noise in order to eliminate clutch, propose on clutch disk, vibration damper to be set, these vibration dampers have high requirements of installation space.In addition, can improve the damping of power train and/or the anti-regulatory function of buffeting is set at the control software that is used for the solenoidoperated cluthes actuator.
Summary of the invention
Therefore, task of the present invention is, a kind of improved damping behavior of double-clutch speed changer is provided, and is particularly useful for avoiding or improving the vibration that is caused by buffeting when friction clutch skids.
This task solves by the double-clutch speed changer in a kind of Motor Vehicle, this double-clutch speed changer has two sub-speed changers, described sub-speed changer respectively has a transmission input shaft, described transmission input shaft can be coupled by the live axle of a friction clutch and driver element respectively, wherein, but be set to can be at least temporarily coupled to each other by at least one rubbing device for the torsion element of two sub-speed changers.At this, especially in the vibration critical state, can improve the damping of the vibration system of the sub-speed changer that is activated by the friction clutch that skids, its mode is that the moment of inertia of the sub-speed changer of not enabled is coupled on the moment of inertia of the sub-speed changer that is activated by at least one rubbing device.
The friction of this at least one rubbing device is in this design like this, but make by the torsion element of the sub-speed changer of not enabled and attach troops to a unit and come the nonuniformity of the sub-speed changer that balance is activated in its acceleration and slowing down of quality, for example the nonuniformity with the transmission input shaft of the friction clutch of for example buffeting in slipping state of this sub-speed changer.For this reason, this friction is preferably adjusted so highly, makes the mean speed of two elements coupled to each other accelerate on synchronous direction and slow down.But should rub by the ground restriction of this degree, and make this at least one rubbing device keep skidding at boost phase with in the decelerating phase.Extract energy having on described at least one rubbing device of high friction factor and/or viscosity coefficient " skidding " of so adjusting torsion element that is loaded to rotate nonuniformity from the sub-speed changer that is activated, cause the rotation nonuniformity decay of this sub-speed changer and the amplitude reduction of this rotation nonuniformity.
This at least one rubbing device can consist of by the mechanical type friction engagement with corresponding friction factor.Alternatively or additionally, the rubbing device that fluid mechanics can be set works, the friction engagement of this rubbing device is adjusted by hydraulic pressure and/or damping viscosity, and its mode is, for example is arranged on the liquid of corresponding adjustment aspect its viscosity between the interface of the rotating element of sub-speed changer.
In an advantageous embodiment, but the described torsion element of sub-speed changer can be transmission input shaft, consists of rubbing device between two transmission input shafts.The formal construction of hollow shaft of holding this solid shaft when transmission input shaft take a solid shaft and one is during as the axle that is arranged coaxially to each other, and the layout of this rubbing device is particularly advantageous.At this, rubbing device can be arranged in diametrically between them with working or be arranged in the axial direction on their end.
In another favourable mode of execution, can alternatively or additionally this at least one rubbing device be arranged between the clutch disk adjacent one another are of two friction clutches.At this, the pressing plate shaft of these friction clutches is to being adjacent to or radially arranging stackedly, and respectively by towards independent pressing plate is loaded, thereby for example the flange part of clutch disk can be placed in mutual friction engagement, the clutch disk of rotation can by the sub-speed changer that is activated be in friction lining in the engagement of skidding with friction clutch, namely by rubbing device and by with respect to static clutch disk braking.
In another advantageous embodiment, this at least one rubbing device can be arranged between the change gear adjacent one another are of two sub-speed changers.At this, can for example one or more synchronizer be used as rubbing device so that static transmission input shaft is coupled to the sub-speed changer that is activated rotation, have on the transmission input shaft that rotates nonuniformity.The rubbing device of this form can be used for simultaneously: before hanging at the sub-speed changer of not enabled the shelves of for example wanting preliminary election, the transmission input shaft of not enabled is accelerated, so that these shelves is synchronously easier.At this, can transmission input shaft be accelerated on the direction of synchronous speed with the operation to the friction clutch of the sub-speed changer of not enabled.This is especially favourable when two friction clutches of double-clutch speed changer can thereby not handled independently of each other by the overlapping ground of unique clutch actuator.
For the efficient that do not limit double-clutch speed changer and this at least one rubbing device excessive loads not, confirmed advantageously, only when occurring nonuniformity (as buffeting and analogue) and/or noise (as gear shift clickly sound and similar sound) maybe occurring rotating, enable this at least one rubbing device.For example can during one of the ground actuating friction clutch that skids, for example during the Motor Vehicle starting-up process, during gearshift procedure or analogue, enable this rubbing device in principle.This is enabled and can carry out according to the information about the friction clutch serviceability that is stored in for the controller of solenoidoperated cluthes actuator.Alternatively or additionally, can obtain the rotation eigenvalue from the activation of controlled rubbing device, the speed discrepancy of friction clutch for example, these rotation eigenvalues are by the sensor sensing and for example be provided for using by the CAN bus.Especially can hang the friction torque of adjusting controlled rubbing device when neutral gear in sub-speed changer according to rotation eigenvalue such as rotating speed, rotational acceleration and similar value.
The operation of this at least one rubbing device can be by the actuator that has arranged for operating dual clutch transmission, for example operate by clutch actuator or speed changer actuator.For example, rubbing device can be controlled by this way by clutch actuator, make friction clutch open fully and the bifurcation point (Tastpunkt) of friction clutch when just beginning carry-over moment between activate this rubbing device.At this; this activation is undertaken and is limited like this by the clutch actuator of the sub-speed changer of not enabled; make and do not activating during greater than the moment that applies on bifurcation point (for example 5Nm) under the friction clutch full open position of correspondence and in clutch torque, therefore be protected and do not make the deterioration of efficiency of double-clutch speed changer.At this can be, two clutch actuators are controlled same rubbing devices or are respectively controlled one and attach troops to a unit to the rubbing device of a clutch actuator, so as the starting-up process that carries out with all possible start gear (for example 1 grade, 2 grades, retreat shelves) and may carry out in other gear can be applied friction torque with restarting of skidding of friction clutch.In the mode of simplifying or when the clutch actuator that two friction clutches are all operated was only arranged, rubbing device can only limit to have the sub-speed changer of preferred start gear.
When operating this at least one rubbing device by the speed changer actuator in sub-speed changer transfer gear shift position, the friction engagement between the rotating element of two sub-speed changers can produce by synchronizer or by independent mechanical type or fluid type friction media.At this, the friction position of double-clutch speed changer inside can be arranged on the idle pulley of shelves and receive between the axle of this idle pulley, axially and/or radially is arranged between the axle or analog of mutually attaching troops to a unit on two sub-speed changers.
In order to be independent of the actuator that has existed and can irrespectively to adjust the friction torque of this at least one rubbing device with these actuators that has existed, this at least one rubbing device can be controlled by independent actuator.For the actuator on this meaning, an actuator by a controller (for example clutch controller and/or gearbox controller) control can be set.Alternatively, this actuator can be set to robot control system(RCS), and in this system, friction torque is preferably automatically adjusted according to the parameter that occurs in double-clutch speed changer such as speed discrepancy, centrifugal force, displacement difference and similar parameter.Alternatively, the simple actuator of magnetic switch form for example can be set, this actuator is according to the control of controller or provide the digital activation situation of rubbing device activate/not activate according to outside parameter.
