摘要： PROBLEM TO BE SOLVED: To improve the operation feeling of a transmission in a downshift operation and in an upshift operation in a low temperature, and prevent the jump out of the gears. SOLUTION: A gear chamfer 8b has a tip chamfer which is opposed to a sleeve chamfer 32b and is formed asymmetric in the circumferential direction. The tip chamfer comprises a longer chamfered section 8c along the same direction as the rotational direction R1 of an output shaft and a shorter chamfered section 8d along the opposite direction. The angle θ3 of the longer chamfered section 8c to the circumferential direction and the angle θ4 of the shorter chamfered section 8d to the circumferential direction meet the relation θ3 >θ4 . The sleeve chamfer 32b has a tip chamfer which is opposed to the gear chamfer 8b and is formed asymmetric in the circumferential direction. The tip chamfer comprises a longer chamfered section 32c along the same direction as the rotational direction R1 of the output shaft and a shorter chamfered section 32d along the opposite direction. The angle θ1 of the longer chamfered section 32c to the circumferential direction and the angle θ2 of the shorter chamfered section 32d to the circumferential direction meet the relation θ1 >θ2 .

摘要： PURPOSE:To prevent the damages at emergency stoppage time by setting both driving device and absorbing device to a torque absorption and control at emergency stoppage, by making a torque absorption setting value the value calculated by equalizing operation from the ratio of the inertia force of both devices and mission ratio and by making the torque transmission smaller. CONSTITUTION:The 1st means consisting of a polarity changeover circuit 17, switches 18A, 19A, A/D convertor 30, memories 31, D/A convertor 32 and changeover switch 33 is provided to the control device 8 of a driving body 1. The 2nd means consisting of multipliers 34, 35, changeover switch 36, mission ratio setter 37 and comparator 38 is provided to the control device 9 of an absorbing body 3 then. Accordingly since the driving body 1 is controlled with the speed reduction by the absorption torque of a fixed value corresponding to the driving torque of immediately before the emergency stop by the emergency stop command STOP, and the absorbing body 3 is controlled speed reduction by the torque calculated with equalizing operation from the mission ratio with the driving body 1 and inertia force GD ratio, the torque transmission for a transmission 2 is made extremely smaller.
摘要翻译：目的：为了通过将驱动装置和吸收装置设置为紧急停止时的扭矩吸收和控制来防止紧急停止时的损坏，通过使扭矩吸收设定值通过均衡运算计算的值与两者的惯性力比设备和任务比例，并使扭矩传递更小。构成：将由极性转换电路17，开关18A，19A，A / D转换器30，存储器31，D / A转换器32和转换开关33组成的第一装置提供给驱动体1的控制装置8。然后，将由乘法器34,35，切换开关36，任务比设定器37和比较器38组成的第二装置提供给吸收体3的控制装置9。因此，由于通过紧急停止命令STOP的与紧急停止之前的驱动转矩对应的固定值的吸收转矩以减速的方式控制驱动体1，并且吸收体3受到转矩的控制减速通过与驱动体1的任务比和惯性力GD <2比的均衡运算来计算，变速器2的转矩传递变得非常小。

摘要： PROBLEM TO BE SOLVED: To prevent the dispersion of supporting rigidity of a shift lever supported on a transmission case, caused by an dimensional error. SOLUTION: Disc springs 17, 21 formed in such a way that the change of repulsion to the change of the flexure quantity is smaller in a second flexural area with the flexure quantity being the specified value or more compared to a first flexural area with the flexure quantity being from zero to the specified value are provided between a shift lever 2 and a transmission case 3, and the shift lever 2 is elastically held in the second flexural area to the transmission case 3.
