Abstract
The utility model relates to a novel double clutch type automatic transmission flexural disk mechanism, which is characterized in that a flexural disk assembly is composed of four flexural disk bodies, six nuts and a spline hub. After abutting tightly, the four flexural disk bodies are in welding connection with the six nuts and further connected with the spline hub. The flexural disk assembly which is located between an engine flywheel and a double clutch is connected with the engine flywheel through bolts and connected with the clutch through a spline. The novel double clutch type automatic transmission flexural disk mechanism enables a transmission system to obtain excellent power performances and good vibration performances and reduces shock loading and axial vibration an engine transmits to the clutch.
Description
Technical field:
The utility model relates to a kind of novel double-clutch automatic transmission flexible disk mechanism, belongs to the automatic gearbox technical field of auto manufacturing.
Background technique:
Along with the fast development of automobile pollution and the rapid increase of amateur driver's quantity, automatic gearbox is just presenting fast development trend.Present automatic gearbox mainly contains hydraulic mechanical type automatic transmission (AT), stepless speed variator (CVT) and double-clutch automatic transmission (DCT).
Realizing on automobile that the self-shifting speed changer is the hydraulic mechanical type automatic transmission, be called for short AT, also is present most widely used automatic gearbox.It does not cut off power shfit, has starting, gear shift is smooth-going, but resisting moment is changed advantage such as self adaption.But shortcomings such as it also has complex structure simultaneously, and difficulty is made, and transmission efficiency is low.
Manually fixedly the shaft type gear-shift transmission is the step change driving mechanism, and its advantage is the efficient height, and cost is low, and mature production technology is widely used in China at present.Shortcoming is the gear shift difficulty, and power interruption during gear shift requires pilot control skilled, so people expect that it can realize automation.Computer Control Technology makes this gear realize that automaitc shfit becomes possibility.Double-clutch automatic transmission (DCT) is the automatic mechanical transmission of a new generation, it has inherited many advantages such as manual transmission transmission efficiency height, installing space compactness, in light weight, low price, fundamentally solved the cut-out power shfit problem that electric control mechanical type automatic speed variator exists, greatly improved the gear shift travelling comfort, guaranteed that vehicle has good power character and shift characteristic.
In double-clutch automatic transmission, each gear driving gear of speed changer is connected with two clutch C1, C2 being provided with on the input shaft respectively by strange, even number gear, and clutch C1, C2 replace transferring power to realize gear switch.
During DCT work, vehicle is earlier with certain gear operation, electrical control unit of automatic transmission (TCU) is judged next gear that is about to the work of entering according to the signal of related sensor, because of this gear clutch separation transferring power not also,, mesh this gear in advance so instruction hydraulic control solenoid valve is controlled gear-shifting actuating mechanism very easily, when vehicle operating reaches shift point, only the clutch separation that need will work simultaneously with another clutch, then makes automobile travel with next gear.In gearshift procedure, the power of motor constantly is passed to wheel all the time, so the gearshift procedure of finishing like this is a power shfit.Vehicle has been realized timing, will improve the gear shift travelling comfort greatly, guarantees that also vehicle has good and economic simultaneously, and aspects such as vehicle oil consumption and discharging are made moderate progress.
Summary of the invention:
The purpose of this utility model provides a kind of novel double-clutch automatic transmission flexible disk mechanism, has the effect that reduces motor impulsive load and vibration, makes power train obtain good power character and vibration characteristics.
The technical solution of the utility model is achieved in that a kind of novel double-clutch automatic transmission flexible disk mechanism, it is characterized in that: the flexible disk assembly is by four flexible disk disk bodies, and six nuts and splined hub are formed; Four flexible disk disk bodies are close to the back and are welded to connect with six nuts, and are connected with splined hub; The flexible disk assembly is connected with bolt with engine flywheel between engine flywheel and double clutch, adopts spline to be connected with double clutch.
Good effect of the present utility model is to make power train obtain good power character and vibration characteristics, and the minimizing motor is delivered to impulsive load and the axial vibration on the clutch.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model mounting arrangements schematic representation;
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further: as shown in Figure 1, a kind of novel double-clutch automatic transmission flexible disk mechanism is characterized in that: flexible disk assembly 4 is made up of 2, six nuts 1 of four flexible disk disk bodies and splined hub 3; Four flexible disk disk bodies 2 are close to the back and are welded to connect with six nuts 1, and are connected with splined hub 3; Flexible disk assembly 4 is connected with bolt with engine flywheel between engine flywheel and double clutch, adopts spline to be connected with double clutch.
As shown in Figure 1 and Figure 2, the working procedure of flexible disk is by six bolts being connected with engine flywheel the moment of torsion of motor to be passed to six nuts 1, nut 1 and four flexible disk disk bodies 2 become one by the mode of welding, four flexible disk disk bodies 2 become one with the mode of splined hub 3 by welding, and the back passes to double clutch by the internal spline of splined hub 3 with moment of torsion.Splined hub 3 adopts the spline interference fit with double clutch, and design guarantees that flexible disk assembly 4 is connected reliably with double clutch like this.The function of flexible disk assembly 4 is to utilize the elastic characteristic of flexible disk to reduce the vibration that motor passes to clutch, comprise the footpath torsional vibration that makes progress and the distortion that axially upward produces that produce in the engine flywheel rotary course, torsional impact and axial vibration that minimizing produces double clutch owing to alignment error.
