Problems solved by technology

In such a case, if there is an auxiliary transmission mechanism other than the transmission mechanism that requires lubrication, if the layout of the transmission mechanism, auxiliary transmission mechanism and dry clutch is not properly arranged, there is a possibility that: The wet area where the speed change mechanism is placed and the wet area where the auxiliary transmission mechanism is placed are separated into two parts, and the number of sealing parts between the dry area and the dry area increases, and the size of the transmission is enlarged

no. 1 Embodiment approach

[0068] Below, based on Figure 1 to Figure 16 A first embodiment of the present invention will be described.

[0069] like figure 1 As shown, the vehicle power transmission device that transmits the driving force of the engine E to the drive wheels W, W through the left and right axles 10, 10 includes: a continuously variable transmission T; a first power transmission switching mechanism S1; a second power transmission switching mechanism S2; and differential D. The first power transmission switching mechanism S1 is capable of switching among a parking position, a reverse position, a neutral position, and a drive position. The second power transmission switching mechanism S2 is switchable between a normal running / engine braking state, an idling stop state, and a failure state.

[0070] Next, based on Figure 1 to Figure 7 The structure of the vehicle power transmission device will be described.

[0071] like figure 1 As shown, the input shaft 11 is composed of an input s...

no. 2 Embodiment approach

[0128] Next, based on Figure 17 A second embodiment of the present invention will be described.

[0129] In the first embodiment, the friction surface 54 of the dry clutch 52 is provided on the first side wall 53a of the clutch drum 53, and the pressure plate 56 is arranged on the second side wall 53b side of the clutch drum 53, but in the second embodiment Among them, the positional relationship between the friction surface 54 and the pressure plate 56 is exchanged, the friction surface 54 is provided on the second side wall 53 b of the clutch drum 53 , and the pressure plate 56 is arranged on the first side wall 53 a side of the clutch drum 53 . As a result, the operation shaft 57 that drives the platen 56 is connected to the actuator 59 through the interior of the hollow input shaft main body portion 11A.

[0130] The transmission housing 60 and the extension portion 53d of the clutch drum 53 are sealed by a sealing member 63A, and the gap between the extension portion 53...

no. 3 Embodiment approach

[0132] Next, based on Figure 18 A third embodiment of the present invention will be described.

[0133] In the first and second embodiments, the actuator 59 of the dry clutch 52 is provided on the first chamber 61 side, but in the third embodiment, the actuator 59 is arranged in the second chamber 62 . That is, in the third embodiment, one end of the separation fork 65 pivotally supported by the fulcrum 64 in the middle is connected to the actuator 59, and the other end of the separation fork 65 is brought into contact with the back surface of the pressure plate 56, and the pressure plate 56 passes The splines are supported by the second side wall 53b of the clutch drum 53 so as to be slidable in the axial direction, thereby driving the pressure plate 56 in the axial direction to engage and disengage the dry clutch 52 .

[0134] The transmission housing 60 and the extension portion 53d of the clutch drum 53 are sealed by the seal member 63A, and the gap between the extension...

Abstract

The invention provides a transmission for a vehicle. A dry clutch is disposed between a driving source output shaft and a transmission input shaft. The large axial size of the transmission is restrained to the minimum. The dry clutch is provided a clutch drum, a frictional face, a friction plate and a press plate. One end side of the clutch drum is connected with the driving source output shaft and the other end side is connected with an input component of an auxiliary transmission mechanism. The frictional face is arranged on the inner surface of the clutch drum. The friction plate is fixed on the transmission input shaft in the interior of the clutch drum and is arranged to be abutted against the frictional face. The press plate is disposed to be capable of pressing the friction plate towards the frictional face in the interior of the clutch drum. By use of sealing parts arranged among a transmission housing body, the clutch drum, an operation shaft and the transmission shaft, a first chamber where the input component and a transmission mechanism are disposed is separated from a second chamber where the dry clutch is disposed, the first chamber is arranged to be a wet space with lubricant oil and the second chamber is arranged to the a dry space without lubricant oil.

Description

technical field [0001] The present invention relates to a vehicle transmission comprising: a transmission input shaft connected to a drive source output shaft driven by a drive source via a dry first clutch; a transmission output shaft connected to a driving wheel; and a speed change mechanism, It is capable of shifting the driving force of the transmission input shaft and transmitting it to the transmission output shaft; The auxiliary transmission mechanism is composed of an input member that rotates integrally with the drive source output shaft, an output member that is connected to the transmission output shaft, and a transmission member that transmits driving force between shafts. The input member and the output member are connected. Background technique [0002] In the dual-clutch type semi-automatic transmission, according to the following patent document 1, such a structure is known that the driving force of the engine is selectively transmitted to the first input sh...
