| 101 | Wheel supporting structure in riding working machine | JP17599384 | 1984-08-24 | JPS6181807A | 1986-04-25 | NAKAMURA KENJI |
| PURPOSE:To easily adjust a vehicle height in a wheel supporting structure in an agricultural tractor or the like, by pivotably mounting a wheel supporting knuckle to an arm vertically swingably pivoted to a body, and interchangeably engaging the knuckle with a plurality of mounting holes of a knuckle holder. CONSTITUTION:Upper and lower brackets 31 and 32 are projected from an inside surface of a reduction case 26. A knuckle 35 is relatively rotatably connected through king pins 33 and 34 to the brackets 31 and 32. A knuckle arm 37 is fixed to the upper bracket 31. The knuckle arm 37 is pivotably connected through a tie rod 38 to a front end of a link mechanism 91. An upper arm 39 is pivotably mounted to an upper portion of the knuckle in such a manner as to be relatively swingable in vertical direction. Right and left knuckle holders 50 are fixed to a differential case 20, and are formed with vertically arranged mounting holes 63-65 to which the knuckle 35 is bolted. Thus, adjustment of a vehicle height may be easily carried out by changing a bolted position of the mounting holes. | ||||||

| PURPOSE:To make frames lightweight and small-sized by slantly forming a pair of the right and left frames near the opposite surfaces of front wheel outer peripheries so that the lower edge is located on the inside of the upper edge and providing brackets for fitting a work machine along the outside surfaces. CONSTITUTION:A pair of the right and left longitudinal frames 3 mounted with a prime mover 1 and fitted with front wheel bearing bodies 2 are slantly formed near the opposite surfaces of front wheel outer peripheries so that the lower edge is located on the inside of the upper edge, and brackets for fitting a work machine are provided along the outside surfaces. By providing the brackets 6 along the slant outside surfaces, the brackets 6 are located nearly along the front wheel outer peripheries even when front wheels supported by the front wheel bearing bodies 2 are turned to the maximum steering angle. Accordingly, it is not necessary to have a large gap between the front wheels and frames, thus the frames can be made small-sized and lightweight. | ||||||

| PURPOSE:To aim at improvements in rigidity in a tractor, by supporting apparatuses including an engine, a transmission case, etc., at the tractor side with a body frame separately made up apart from the tractor side. CONSTITUTION:A body frame makes up long symmetrical frames 5 in a way of attaching a front end part of symmetrical intermediate frames 2 to a rear end part of symmetrical front frames 1. These symmetrical frames 5 are coupled with each of cross frame members 6a-6c, forming a front frame 7. Two of upper and lower symmetrical frames 8 and 10 are attached to a rear end of the front frame 7, forming a rear frame. An engine 25 is supported on cross frames 6c and 6d via vibro-isolating rubber, while a clutch housing 26 is combinedly koined to the engine 25 and a transmission case 13. In addition, apparatuses including a battery, a radiator, a power steering, etc., are also supported by a plate 30 being projectingly installed in these symmetrical front frames 1. | ||||||

| 106 | Agricultural tractor with car height changing device | JP15303282 | 1982-09-01 | JPS5940909A | 1984-03-06 | TERAOKA AKIRA |
| PURPOSE:To improve the maneuverability at a high bed status and allow the entrance into an orchard at a low bed status by placing the car body lower surface of a front wheel section at nearly the middle between the top of the ground ruggedness and the top of a high furrow as a standard car height posture and making the up-and-down movement of the rear wheel larger than that of the front wheel. CONSTITUTION:The lower surface of a front axle case 11 is placed at nearly the middle position (d) between the height (b) of the road ruggedness A and the height (c) of a high furrow B as a standard posture. Thereby, when the car height is to be changed from the standard posture, the up-and-down movement of a rear wheel 10 can be set larger by a clearance (a) than that of the front wheel 11. Accordingly, during a cultivating work a transmission case 30 has a ground height of a+d, thus allowing stable travelling, and at a high bed posture for a high furrow work a forward tilting posture allows stable travelling. In addition, at a low bed posture a backward tilting posture gives a clearance above the driver's head, thus allowing the easy entrance into an orchard. | ||||||
