Description
Technical field
The present invention relates to a kind of car of new model dry dual clutch formula automatic transmission double clutch assembly of (Double Clutch Transmission is called for short DCT).
Background technique
At present, the double clutch assembly of existing dry dual clutch formula automatic transmission is mainly comprised of front clutch, front clutch actuator, rear clutch, rear clutch actuating mechanism and clutch driving plate.Its clutch driving plate is arranged between the clutch of front and back, front clutch be arranged in clutch driving plate before, rear clutch be arranged in clutch driving plate after, the joint by clutch before and after controlling respectively and clutch driving plate carrys out transferring power with separated.Yet, because the power input side (front of front clutch) of double clutch assembly will connect power source, therefore before and after, the actuator of clutch is all arranged on the power outlet side (back of rear clutch) of double clutch assembly, the release bearing of front and back clutch nests together, complex structure, controls difficulty larger.
Summary of the invention
The object of the invention is to propose a kind of double clutch assembly that improves the vehicle dry type two clutches formula automatic transmission of structure, can make the mutual noninterference in joint and separation process of two clutches, simplify mechanical structure simultaneously, reduce and control difficulty.
The double clutch assembly of vehicle dry type two clutches formula automatic transmission of the present invention, comprise: the double clutch housing being connected with automobile power input shaft, be installed in the clutch driving plate in double clutch housing, be separately positioned on clutch driving plate both sides by the separated platen of front clutch, front diaphragm spring, front clutch platen, the front clutch that front clutch driven disc forms and by rear clutch compressing disc, rear clutch driven plate, the rear clutch that rear film spring forms, described front clutch driven disc, rear clutch driven plate is driven and is connected with rear clutch output shaft with the concentric front clutch output shaft being nested with by spline respectively,
The center of described front clutch platen is connected with front clutch release rod by front clutch thrust bearing, front clutch release rod is and coordinates the intermediate throughholes the inside that is set in front clutch output shaft, by its axial front and back, is slided and is realized front clutch driven disc with the separated of clutch driving plate or engage;
On described rear clutch output shaft the nested rear clutch release bearing sliding before and after can be axially connected to after the inner edge place of clutch diaphragm spring, by rear clutch release bearing, slide before and after axially realize after clutch driven plate and the separated of clutch driving plate or engage.
The present invention adopt two kinds of dissimilar actuators control respectively before and after the joint of clutch with separated, with respect to traditional dry dual clutch assembly, reduced by a release bearing, but passing a push rod in the centre of front clutch output shaft, the joint that employing push rod platen separated with front clutch controlled front clutch is with separated.This designs simplification double clutch housing, avoided labyrinth that two release bearings are nested together, control lighter.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the present invention.
As shown in Figure 1, 2, the double clutch assembly of vehicle dry type two clutches formula automatic transmission of the present invention, comprises front clutch, front clutch actuator, rear clutch, rear clutch actuating mechanism and clutch driving plate.
Described front clutch comprises: the separated platen 2 of front clutch, front diaphragm spring 3, front clutch platen 4, front clutch driven disc 5; The center of front clutch platen 2 is connected with front clutch release rod 10 by front clutch thrust bearing 14, the outer rim of front clutch platen 2 is fixedly connected with the inner edge of front diaphragm spring 3, the outer rim of front diaphragm spring 3 is fixedly connected with double clutch housing 1, the intermediate support of front diaphragm spring 3 connects front clutch platen 4, and front clutch driven disc 5 is between front clutch platen 4 and clutch driving plate 6.
Described front clutch actuator refers to front clutch release rod 10, is positioned at the middle through hole the inside of front clutch output shaft 11, and axially slide in front and back, and its front end acts on the center of the separated platen 2 of front clutch by front clutch thrust bearing 14.
Described rear clutch comprises: rear clutch compressing disc 7, rear clutch driven plate 8, rear clutch diaphragm spring 9; Rear clutch compressing disc 7 is connected on the fulcrum of rear film spring 9 outer rims, the intermediate support of rear clutch diaphragm spring 9 is fixed on double clutch housing 1, the inner edge of rear film spring 9 is point of action of rear clutch release bearing 13, and rear clutch driven plate 8 is between rear clutch compressing disc 7 and clutch driving plate 6.
Described rear clutch actuating mechanism refers to rear clutch release bearing 13, is nested on rear clutch output shaft 12, and axially slide in front and back, directly acts on the inner edge place of rear clutch diaphragm spring 9.
Described clutch driving plate 6 is fixedly connected with double clutch housing 1, and forward and backward both sides are respectively front clutch driven disc 5 and rear clutch driven plate 8.
The working principle of the double clutch assembly of vehicle dry type two clutches formula automatic transmission of the present invention:
Double clutch assembly when normal operation, former and later two clutches conventionally only have one in running order.
The pretightening force of the forward diaphragm spring 3 of front clutch platen 4 compresses transferring power, rear clutch compressing disc 7 compresses transferring power by the pretightening force of rear film spring 9, and the pretightening force of front diaphragm spring 3 and rear film spring 9 needs to be adjusted in advance in suitable number range when mounted.
When needs front clutch is separated, front clutch release rod 10 promotes forward front clutch thrust bearing 14, by front clutch thrust bearing 14, promoting the separated platen 2 of front clutch moves forward, the separated platen 2 of front clutch drives the inner edge of front clutch diaphragm spring 3 to move forward, because the outer rim fulcrum of front clutch diaphragm spring 3 is fixed on double clutch housing 1, therefore the intermediate support of front clutch diaphragm spring 3 drives front clutch platen 4 to move forward, make front clutch in separated state, not transferring power.
When needs front clutch engages, front clutch release rod 10 moves backward, under the effect of front diaphragm spring 3 pretightening forces, the separated platen 2 of front clutch moves backward together with front clutch thrust bearing 14, the pretightening force of front diaphragm spring 3 makes front clutch platen 4 compress backward front clutch driven disc 5 simultaneously, therefore front clutch, in jointing state, starts transferring power.
After needs during clutch separation, rear clutch release bearing 13 is pressed forward rear clutch diaphragm spring 9, because the intermediate support of rear clutch diaphragm spring 9 is fixed on double clutch housing 1, the outer rim of rear clutch diaphragm spring 9 moves backward, thereby after driving, clutch compressing disc 7 moves backward, make rear clutch in separated state, not transferring power.
When after needs, clutch engages, the pretightening force of rear film spring 9 is moved rear clutch release bearing 13 backward, simultaneously the pretightening force of rear film spring 9 makes rear clutch compressing disc 7 press to forward rear clutch driven plate 8, because clutch is after this in jointing state, and beginning transferring power.
