| PROBLEM TO BE SOLVED: To increase the gear shift range of a drive axle and/or reduce a load on a transmission mechanism, and secure a free space between front wheels and rear wheels while effectively suppressing an increase in the overall length of a vehicle. SOLUTION: A variable output type HST and a planetary gear device are connected to an engine vibrationproof-supported on one side of a body frame in the longitudinal direction of the vehicle to form a drive side unit integrally vibrationproof-supported by the body frame. The transmission case of a transmission is fixedly supported on the body frame on the other side of the vehicle in the longitudinal direction in the state of being separated from the drive side unit. The output element of the planetary gear device is operably connected to the wheel driving drive train of the transmission through a shaft joint extending along the longitudinal direction of the vehicle.

| PURPOSE:To enable a selective carrier lift and changeover of said lift to be carried out easily by using pulleys and a chain, whose force end is formed into a special structure, and making said end freely attachable to the chain or a mast. CONSTITUTION:By means of a pulley 31 and a chain 29, a joint 51, or an end of the chain 29, can be installed selectively to a mast 16 or the chain 29. The joint 51 is made up of linking clicks 47 and 48, which are inserted between adjacent chain shafts, and a pull-out-preventing piece 49. Since the connection between the joint 51 and the chain 29 can easily by disconnected by pulling off, a pin 54 changeover of the lift can be carried out easily. | ||||||

| 76 | Lifting device utilizing triangular links | JP14917981 | 1981-09-21 | JPS5849561A | 1983-03-23 | SUZUKI SADAO |
| PURPOSE:To facilitate a re-stacking job and to prevent stacked cargoes from falling down by freely setting the rear end of a upper link either to a position parallel to a lower link or to a position satisfying a relation where said rear end gradually separates from said lower link as it goes backward. CONSTITUTION:If the rear end of a upper link 9 is engaged with an engaging part 33 on the lower side of a mast frame 25, and a lower link 5 is lifted by a lift arm 7 and a rod 8 keeping said state, a mast frame 25 can be lifted while being kept in vertical attitude, since the lower link 5 and a upper link 9 satisfy the link mechanism relation of a parallelogram. When the ground 32 is uneven, the rear end of the upper link 9 should be engaged with an engaging part 34. Then, the stacked cargoes will not fall down since a lift 37 is inclined forwardly. | ||||||

| PURPOSE:To facilitate a re-stacking job and to prevent stacked cargoes from falling down by freely setting the rear end of a upper link either to a position parallel to a lower link or to an upper position not parallel to it. CONSTITUTION:A mast frame 25 is made vertical and a upper link 9 is made parallel to a lower link 5, in this state. And, a lowr engaging part 33 is formed in a position where the rear end of said upper link 9 is engaged, so that an engaging part 34 is provided on the upper part. Supporting the rear end of the upper link 9 on the engaging part 33 enables a lifting device 37 to be moved up and down while being kept in horizontal altitude, providing a suitable state for a job such as the re-stacking of a cargoes. On the other hand, supporting the rear end of the upper link 9 on the engaging part 34 makes it possible to prevent stacked cargoes from falling down since the lifting device is forwardly inclined when it is made to move in the upper direction. | ||||||
