摘要： PURPOSE:To brake the overrun by overdriving at a desired reduction ratio smaller than 1 in braking the sun gear of the planetary gears after disengaging the sun gear and other element by means of a clutch. CONSTITUTION:An auxiliary change gear 200 is arranged between a change gear of 3-steps forward gears and 1-step rearward gear, having two sets of coaxial planetary gears, and a torque converter 2 connected to the engine output shaft 1. The input shaft 3 and the output shaft 4 of the auxiliary change gear 200 are disposed coaxially with a planetary gears 8 comprising a sungear 21, a planetary pinion 22, and a ring gear 23. The input shaft 3 is engaged with a carrier 24 of the pinion 22, the output shaft 4 is engaged with the ring gear 23, and the sun gear 21 and the carrier 24 are disengageably connected with a clutch 11. A brake 14 brakes the turning of the sun gear 21. A one-way clutch 20 is provided between the sun gear 21 and the carrier 24.

摘要： PURPOSE:To improve the drive feeling of an automobile, by checking the vehicle speed or engine revolution at the time of controlling a manual change gear and setting an optimum gear changing diagram for each stage of gear changes according to the checked values. CONSTITUTION:Besides a manual change gear, an auxiliary change gear functions through selective control of its built-in brake and clutch device by means of solenoid devices 30, 31 which are controlled by a selective controller equipped with a computer 50. The computer 50 receives signals from a speed sensor 51, throttle valve sensor 52, shift position sensor 53 and clutch sensor 54, sets and optimum speed control diagram for each stage of the manual change gear and selectively controls the auxiliary change gear according to the diagrams.

摘要： PURPOSE:To consitute a transmission shaft portion with two shafts and miniaturize and lighten a device by arranging an input shaft and a drive gear shaft coaxially. CONSTITUTION:An input shaft 1 is supported in a transmission case 50 by bearings and a lower range driving gear 9 is rotatably supported thereon. A drive gear shaft 2 is arranged coaxially with the input shaft 1 and is formed to be integral with gears 10-13 for 1-4 speed stages and a reverse gear 14 or is fixing these gears so as to rotate integrally therewith. Further, two pairs of gears 9, 15, constituting a high- speed gear ratio of a low-speed gear ratio, are provided between the input shaft 1 and the shaft 2. A transmission portion is consisting of two shafts as abobe-described, therefore, one pair of gears are engaging for one speed stage, consequently, the transmission effeciency is higher than those of ordinary transmissions.

摘要： PURPOSE:To operate a sub speed changer and switching operations for four wheels with single operating lever by controlling a coupling operation between a shift member and an operating shaft. CONSTITUTION:When an operating lever 72 is shifted to a position FF for a front drive, a synchromesh mechanism 40 for driving rear wheels is not engaged with a gear 38, therefore, rear wheels are not driven, while front wheels are driven at a high-speed range without speed reduction by a sub speed changers. When the operating lever 72 is shifted to a position 4WD4 where four wheels drive in economical running range may be effected, the synchromesh mechanism 40 is shifted to the left and is engaged with the gear 38, therefore, both front and rear wheels are driven at high-speed range with four steps speed change without speed reduction by the sub speed changers. Further, when the lever 72 is shifted to the position 4WDp of a high-output side, a sleeve 41 for the synchromesh mechanism 12 is moved and an engagement between a gear 11 and the synchromesh mechainsm is effected, and thereby, the front and rear wheels are driven at low-speed range with four steps speed change.

摘要： PURPOSE:To plan to miniaturize a device by providing at a position between a clutch mechanism and a main speed changer with a space and arranging terminal reduction gears for driving fornt wheels and a sub speed changer therewithin. CONSTITUTION:A space is provided between a clutch 2 attached to a first main drive shaft 3 and a main speed changer M, and terminal reduction gears 30, 31 for driving front wheels and a sub speed changer S are arranged at the upper and lower side therewithin. By this arrangement, an engine output is delivered to a second main drive shaft 10 with a speed not reduced by the sub speed changer S through the clutch 2, the first main drive shaft 3, a gear 5 and a sleeve 41 for a synchromesh mechanism 12, while the main speed changer M delivers the revolution of the second main drive shaft 10 to a third main drive shaft 21 through four-steps speed change gears, and thereby, drives front wheels through the terminal reduction gears for driving front wheels 30, 31. By the specified arrangement of the sub speed changer S and the terminal reduction gears 30,31, front wheels may be arranged at convenient positions where are comparatively nearer to a front portion relative to a chassis, and a special space for the sub speed changer S becomes unnecessary,a nd thus, a desired object may be achieved.

摘要： PURPOSE:To provide an arrangement for industrial vehicle driving system, in which main shaft and clutch shaft are connected together in freely detachable manner by means of a lock pin, and the main shaft is arranged to be movable in axial direction so that gears and synchronizing unit can be detached freely, whereby it is enabled to detach only required parts for replacement of the same. CONSTITUTION:Main shaft 9 is coupled with clutch shaft 2 by means of spline 9a formed on the inner surface of clutch at the end portion, such that relative axial movement of main shaft 9 toward clutch shaft 9 toward clutch shaft 2 is permitted. Further, a lock pin 14 is inserted so as to impose restriction on the relative axial movement of main shaft 9. With such an arrangement, main shaft 9 is set free from clutch shaft 2, front and rear gears 19, 21 and synchronizing unit 20 can be shifted axially toward clutch, after removing lock pin 14 and snap ring 24. Then, gear 21, synchronizing unit 20 and gear 19 can be disassembled from main shaft 9 for replacement of the same.
