摘要:
A drive unit case (920) in this engine unit is provided with a crank shaft (60) disposed in the left-right direction of the vehicle, a drive shaft (73) and a second main shaft (72). A transmission shaft (79) is disposed parallel to the drive shaft (73) and transmits rotational power, which has been transmitted via a middle gear (76), to a propeller shaft (65). A second clutch (75), which transmits rotational power from the crank shaft (60) to the second main shaft (72), is connected freely detachably to an end (72a) of one side of the second main shaft (72) which protrudes from a drive unit case (920) more than the end of one side of the drive shaft (73), at a position that overlaps with at least one section of the middle gear (76) on the side of the shaft direction of the drive shaft (73).

An automatic shift apparatus (13) including a rotation shaft (23, 24), a dog clutch gear shift mechanism (252), and a control unit (26). The control unit (26) supplies a predetermined electric current (Ia) to a shaft moving apparatus (313) to move a sleeve (312) in an engaged state engaged with one of a first clutch ring (281) and a second clutch ring (282) and supplies a braking electric current (ID) smaller than the predetermined electric current (Ia) to the shaft moving apparatus (313) to exert a braking force on the sleeve (312), the braking force directed in the opposite direction relative to a direction of movement of the sleeve (312), before a spline (312a) of the sleeve (312) disengages from a first dog clutch portion (281 a) or a second dog clutch portion (282a) of the mentioned one of the first clutch ring (281) and the second clutch ring (282).

A motor drive assembly for a vehicle is proposed which can prevent a two-way roller clutch of the current speed ratio and a two-way roller clutch of the next speed ratio from engaging simultaneously. This assembly includes a first-speed friction plate (52a) formed with engaging protrusions (66a) on the first-speed side, a shift ring (51) formed with engaging recesses (65). While the shift ring (51) is in a first-speed shift position SP1f, the engaging protrusions (66a) are adapted to be engaged in the engaging recesses (65), thereby preventing rotation of the shift ring (51) relative to the first-speed friction plate (52a). The shift ring (51) is further provided with projections (63) on its inner periphery. The drive assembly further includes an annular protrusion (58) formed with cutouts (62). When the projections (63) are axially and circumferentially displaced from the respective cutouts (62), the projections (63) are adapted to interfere with the annular protrusion (58), thereby preventing axial movement of the shift ring (51) between the first-speed shift position SP1f and a second-speed shift position SP2f.

摘要:
One object of the present invention is to provide a power transmitting apparatus which can improve its power transmitting efficiency with reducing the speed shift time lag as well as reducing the longitudinal dimension of the input shaft and thus a whole longitudinal dimension of the power transmitting apparatus. According to the present invention there is provided a power transmitting apparatus comprising a plurality of gear stage clutch means arranged on the way of a power transmitting path between an engine and the wheels, the input from a input shaft of the engine side and the output to the wheel side of the gear stage clutch means being set at predetermined gear ratios; and a gear stage selecting means being able to select any one of the gear stage clutch means in accordance with the running condition of a vehicle and to arbitrarily set the gear ratio during power transmission from the engine to the wheels characterized in that each of said gear stage clutch means comprises alternately arranged driving clutch discs and driven clutch discs; hydraulic pistons actuated by hydraulic oil to selectively engage or disengage the driving clutch discs and driven clutch discs; hydraulic chambers for actuating the hydraulic pistons; and supplying ports communicating with oil passages formed within the input shaft and opening on the side surface of the input shaft for supplying the hydraulic chambers with hydraulic oil from the oil passages to actuate the hydraulic pistons; that the power can be transmitted at a predetermined gear ratio with engaging the driving clutch discs with driven clutch discs of the gear stage clutch means of an arbitrary gear stage by selectively supplying hydraulic oil to the hydraulic chambers ; and that a plurality of the supplying ports are formed on a same plane of a radial cross-section of the input shaft.
