摘要： A transmission shaft (62) mounting thereon fluid-operated clutch means (68) which discontinues selectively the input of power to such shaft is enclosed at one end portion thereof by a hollow cylinder (86) projected inwardly from an inner wall surface of transmission case (28) for power transmission. An annular groove (89) formed to said one end portion of shaft (62) at the outer peripheral surface thereof and communicated to the clutch means (68) via fluid path (85) in the shaft (62) is sealed by the hollow cylinder (86) so as to form an annular fluid chamber (90) which constitutes a rotary joint portion of fluid conduit line for the clutch means (68). Braking mechanism of a brake (69) associated with the clutch means (69) for braking the shaft (62) in the non-operated state of clutch is arranged within the hollow cylinder (86) by employing such cylinder as brake case. The rotary joint portion and brake (69) are thus arranged within transmission case (28) without a need of structure arranged outside the case (28).
摘要翻译：安装在其上的流体操作的离合器装置（68）上的传动轴（62）通过从变速器壳体的内壁表面向内突出的中空圆筒（86）封闭在其一端部上（28）用于动力传递。通过轴（62）中的流体路径（85）在其外周面上形成于轴（62）的一端部并与离合器装置（68）连通的环形槽（89）被中空筒（86），以形成构成用于离合器装置（68）的流体导管线的旋转接头部分的环形流体室（90）。在离合器的非操作状态下用于制动轴（62）的离合器装置（69）的制动器（69）的制动机构通过采用这种气缸作为制动器壳体布置在中空圆筒（86）内。因此，旋转接头部分和制动器（69）被布置在变速箱（28）内，而不需要布置在壳体（28）外部的结构。

摘要： Transmission for working vehicles having forcedly driven rear wheels (2) as well as rear-PTO shaft (17) and mid-PTO shaft (19) for driving working implements is disclosed. The transmission includes a hydrostatic transmission (7) fixedly provided on the front of transmission case (8) so as to use pump shaft (23) thereof for the input of working implement-driving power at a high level into transmission case (8) from which the rear-PTO shaft (17) extends backwardly at a middle level and so as to permit a low level arrangement of the mid-PTO shaft (19). Within the transmission case (8), clutch means (31, 36) and speed-change means (32) for PTO-line are arranged at an upper half whereas speed-change gearing (43) and differential gearing (44) for vehicle drive line are arranged at a lower half by employing motor shaft (22) of the hydrostatic transmission as input shaft. A compact arrangement of transmission components is achieved so that transmission case (8) may be reduced in length as well as in weight.

摘要： An auxiliary speed change mechanism (10) disposed within a rear portion of a tractor clutch housing (1) is supported by a support frame (11) comprising axially spaced front and rear bearing support plate members (11a, 11b) which are integrally connected by upper and lower connecting plate members (11c, 11d). The change mechanism includes two sets of constant-mesh gears (8, 9, 12, 13) and is operated by a shifter fork (17) which is supported by the support frame through a guide shaft (16). This structure facilitates an easy pre-assembling procedure of the change mechanism which is then installed into the tractor by securing the support frame to a front of a transmission casing (3) to be secured to the rear of the clutch housing. An integral, internal partition wall (1a) is provided in the clutch housing for interrupting lubricant oil for the change mechanism from a main clutch (2) which is disposed within a front end portion of the housing.

摘要： In a self-propelled walking mower having a deck as a machine frame for supporting an engine, mowing cutter and front wheels, a transaxle-type transmission for driving rear wheels is housed at a rear end portion of the deck in a transmission casing an upper half of which is provided by a portion of top wall of the deck and by a peripheral wall which is formed integrally with the deck and projected downwardly from the top wall of deck. The transmission may be assembled in a lower half of the transmission casing, or alternatively in the upper half, and then the two casing halves may be secured together for completing an essential part of the mower drive system. The upper casing half integral with the deck contributes not only to an easy assemblage of the drive system but also to a reduction of weight and size of the mower.

摘要： Within a transmission casing (3) having therein a drive shaft (4), driven by an engine (1) through a main clutch (2), and a hollow speed-change shaft (5), a key-shift transmission mechanism (8) is disposed which comprises a plurality of meshing gears (9I-9V, 10I-10V) mounted respectively on the drive and change shafts. An axle (6) drivingly connected to left and right drive wheels (7) extends through the hollow change shaft. One end of the change shaft is spaced from an inner wall surface of the transmission casing for disposing therebetween an auxiliary clutch (13) which is operable between the change shaft and axle. Both of the main and auxiliary clutches are operated together.The transmission mechanism is provided for a plurality of variable speeds of a mower in a compact fashion owing to a co-axial arrangement of the hollow change shaft and the axle passing therethrough. The auxiliary clutch which is provided also in a compact fashion permits to shift the transmission mechanism lightly and to pull the mower for retreating same with ease.
