Field of the Invention The present invention relates to a transmission for a vehicle, and more particularly to a transmission for a vehicle in which a start operation is partially automated by combining a gear transmission having a power cutoff clutch and a fluid transmission.

させている。In a transmission for a vehicle, a fluid coupling is inserted between an engine and a power cut-off clutch to transmit torque of the engine when the power cut-off clutch is connected to the fluid coupling so as to transmit engine power to a gear transmission mechanism. There is a technique for doing so (see Japanese Patent Laid-Open No. 59-147156).
In such a transmission, it is possible to expect abrupt torque fluctuations to be absorbed by the fluid coupling, so it is possible to perform start-up and off-throttle shifting without subtle clutch connection operation or without clutch operation, and no skill is required. You can enjoy driving by manual gear shifting operation. On the other hand, when the power is transmitted through the fluid in this way, the power transmission loss becomes large, and therefore, if the vehicle always travels in such a state, the fuel consumption is significantly deteriorated. Therefore, in the above-mentioned conventional technique, a direct coupling clutch (lock-up clutch) is arranged in parallel with the fluid coupling, and this is controlled by the hydraulic pressure generated by the oil pump, so that the fluid coupling can be used at the time of cruising with little fluctuation in the transmission torque. The pump and the turbine are directly connected to improve the transmission efficiency.

い。By the way, in a vehicle equipped with a manual transmission in which an ordinary gear transmission mechanism and a power cut-off clutch are combined, a state in which gears at arbitrary shift stages of the gear transmission mechanism are engaged during parking. By so doing, the engine of the vehicle can be directly connected to the drive system via the power cut-off clutch and the gear speed change mechanism, and an auxiliary parking brake function using the engine as a braking load can be exerted.
However, in the combination of the manual transmission and the fluid coupling, such as the technique disclosed in Japanese Patent Laid-Open No. 59-147156, the engine and the transmission are connected via the fluid coupling during parking, so A fluid slip occurs between the pump and the turbine, and the action as a brake cannot be obtained.

In the vehicle transmission device, the fluid transmission device includes an oil chamber to which hydraulic pressure is supplied from the oil pump, and a connection mechanism between the pump and the turbine on which hydraulic pressure supplied to the oil chamber acts. The connection mechanism is characterized by releasing the connection between the pump and the turbine by supplying hydraulic pressure to the oil chamber.

行うことができる。According to the constitution of the above-mentioned claim 1,
When the engine is stopped, the oil pump is also stopped, hydraulic pressure is not supplied to the oil chamber of the fluid transmission, and the connecting mechanism keeps the pump and the turbine connected. Therefore, when the vehicle with the engine stopped is parked, the drive system and the engine are directly connected to each other by meshing the gears of any gears of the gear shift mechanism, so that an auxiliary parking brake action can be obtained. . Further, when the engine is operating, the hydraulic pressure generated by the oil pump is supplied to the oil chamber of the fluid transmission device, and the supplied hydraulic pressure causes the coupling mechanism to release the coupling between the pump and the turbine. As a result, the output torque from the engine is transmitted to the speed change mechanism via the fluid transmission device, so that a difficult clutch operation can be easily performed.

維持させることができる。Further, according to the second aspect of the present invention, when the engine is stopped, the oil pressure from the oil pump is not supplied to the oil chamber of the fluid transmission, and the oil pressure of the oil chamber is discharged from the discharge oil passage to the connecting mechanism. Since hydraulic pressure does not act, the connecting mechanism keeps the hydraulic transmission in a locked state by connecting the pump and the turbine. When the engine is operating, the hydraulic pressure supplied from the oil pump to the oil chamber acts on the coupling mechanism, and the discharge oil passage discharges oil while maintaining the oil pressure in the oil chamber. It is possible to maintain the release state of the coupling mechanism while preventing the oil temperature in the fluid transmission device from rising due to circulation.

The pump and the turbine can be mechanically and automatically maintained in the connected state.

にすることができる。Next, when the engine E is started by releasing the clutch 10 or releasing the meshing of the gears of the shift stage by the previous operation of the speed change mechanism 30, the oil pump 50 is also activated. Then, the oil pressure is generated, and this oil pressure is applied to the oil passage in the transmission case, the oil passage between the shafts, etc.
The hydraulic pressure supplied to the facing portion between the pump 21 and the turbine 22 of the fluid coupling 20 through an appropriate oil passage as indicated by the arrow in FIG. 2, and thus supplied to the fluid coupling 20 passes through the supply oil passage 51. The oil is also supplied to the oil chamber 25, the sleeve 26 is pushed back against the biasing force of the spring 27, and the engagement between the inner peripheral spline 262 and the outer peripheral spline 281 shown in FIG. 3 is released. Eventually, torque transmission by the fluid coupling 20 is started. The hydraulic pressure supplied to the oil chamber 25 drops when passing through the orifice 52 having a small flow capacity, and is discharged as an exhaust pressure.
The oil is collected in an oil reservoir or the like through the drain oil passage 53, the in-shaft oil passage, and the like, and is repeatedly returned to the suction side of the oil pump 50. Such oil circulation is maintained throughout the engine operation. The release timing of the connected state by the sleeve 26 can be appropriately set according to the relationship between the urging force of the spring 27 and the oil pump discharge pressure.
The release can be maintained when the engine E is idling.

The first input shaft 31 through the turbine 22 via the fluid inside
However, in the neutral state of the gears of each stage of the speed change mechanism 30, the output shaft 33 is blocked. Therefore, when the forward first speed is selected (N → 1 shift), the clutch 10 is disengaged and the synchromesh mechanism 336 on the output shaft 33 is shifted to operate the output gear 331 of the first speed, similarly to the conventional manual shift operation. Is connected to the output shaft 33. After that, if the clutch 10 is connected in the same manner as in the case of a normal gear shift, the slip of the fluid in the fluid coupling 20 buffers the torque shock to gradually transmit the power, and eventually the steady power transmission state is reached. Similarly, when selecting reverse (N → R shift), the clutch 10 is disengaged and the reverse gear 34R
The power transmission via the three gears 31R, 34R, 33R may be established by meshing with the reverse input gear 31R and the reverse output gear 33R, and the clutch 10 may be similarly connected.

During the shift), the clutch 10 is disengaged, and the second speed output gear 332 is connected to the output shaft 33 by the shift operation of the synchromesh mechanism 336 on the output shaft 33. The clutch connection at this time is exactly the same as that of the conventional manual shift operation, and the clutch connection operation is slightly gentler than when selecting a higher gear (2 → 3, 3 → 4, 4 → 5 shifts). The occurrence of a large gear shift shock can be avoided by carrying out the operation, and this operation is not particularly difficult. The third speed or higher is selected by selecting the synchromesh mechanism 32 on the second input shaft 32.
The same operation as above is performed by the shift operation of 6,327.

As a result, the output torque from the engine E is transmitted through the fluid coupling 20 to the speed change mechanism 3
Since it is transmitted to 0, a difficult clutch operation can be facilitated. Further, when the engine is stopped, the oil pump 50 is stopped, the oil pressure is not supplied to the oil chamber 25, and the piston-actuated sleeve 26 connects the pump 21 and the turbine 22. Therefore, when the engine is stopped, the transmission mechanism 30
The drive system 40 and the engine E are directly connected to each other by meshing the gears of any of the gear positions described above, whereby an auxiliary parking brake action can be obtained. Further, when the engine is operating, the hydraulic pressure supplied from the oil pump 50 to the oil chamber 25 through the supply oil passage 51 acts on the piston portion 261, and the hydraulic pressure of the oil chamber 25 is discharged and circulated from the discharge oil passage 52. It is possible to prevent a rapid rise in oil temperature.
Further, when the engine is stopped, the oil pressure from the oil pump 50 is not supplied, the oil pressure in the oil chamber 25 is discharged from the orifice 52, and the oil pressure does not act on the piston portion 261, so that the sleeve 26 connects the pump 21 and the turbine 22. can do. Further, when the engine is stopped, the oil pressure generated by the oil pump 50 disappears, so that the sleeve 26 is urged by the spring 27 to move the sleeve 26 to the pump 2
1 and the turbine 22 can be maintained in a connected state.

ない。In the transmission of the above-mentioned embodiment, unlike the conventional transmission described at the beginning, the input shaft of the speed change mechanism has an inner / outer dual shaft structure, and the input gears for the second to fifth speeds are arranged. Since the second input shaft 32 is connected to the pump 21, when the engine is stopped, the gears of the second to fifth speeds of the speed change mechanism 30 are also meshed with each other so that the drive system 40 and the engine E can be connected. Although it can be directly connected and an auxiliary parking brake action can be obtained, the first input shaft 31 provided with the input gears for the first speed and the reverse gear is the turbine 22
Since the vehicle is connected to the vehicle, the parking action cannot be obtained without the operation of the connecting mechanism according to the subject matter of the present invention.
