摘要： A shift control device for a work vehicle that has a stepped automatic transmission includes: a control device that controls an engine rotation rate at the work vehicle and the stepped automatic transmission; a forward/reverse switchover member that outputs a forward/reverse switchover command for the work vehicle; and an operation quantity detection device that detects an accelerator pedal operation quantity in the work vehicle is operated. As the forward/reverse switchover command is output via the forward/reverse switchover member, the control device executes forward/reverse switchover control for the stepped automatic transmission and also controls the engine rotation rate so as to decrease the engine rotation rate gradually to a target lower limit value selected to ensure that a reverse rotation of a turbine runner at a torque converter in the work vehicle does not occur.
摘要翻译：一种具有阶梯式自动变速器的作业车辆的变速控制装置，具备控制上述工作车辆的发动机转速和阶梯式自动变速器的控制装置，正向/反向切换构件，其输出作业车辆的前进/后退切换命令; 并且操作检测作业车辆中的加速器踏板操作量的操作量检测装置。由于正向/反向切换命令通过前进/后退切换部件输出，所以控制装置对步进式自动变速器进行前进/倒退切换控制，并且还控制发动机转速，从而将发动机转速逐渐降低到目标选择的下限值，以确保不会发生在工作车辆中的变矩器处的涡轮转轮的反向旋转。

摘要： Front wheels (3) are attached to transmission devices (30) which are mounted to the vehicle body (2) to be rotatable around vertical axes (27), and rotating means (55) are provided between the side of the vehicle body (2) and the transmission devices (30), whereby the front wheels are steered to turn laterally at substantially right angles. An electric motor (40) is attached to the transmission device (30) to be located under the vertical axis (27). A case body (41) of the electric motor (40) is constructed by an outer case part (41A) and a non-loaded side bracket (41B), and a loaded side end portion of the outer case-part (41A) is connected to the transmission device case body (31). The drive shaft (44) is rotatably supported by the non-loaded side bracket (41B) at one end and by the transmission device case body (31) at the other end. A driving portion (34) provided at the other end side of the drive shaft (44) is operatively connected to an axle (28). As a result, a traveling drive device section can be constructed to be compact with assembling easiness.
