Abstract

PURPOSE:To aim at making a transmission casing lightweight, by mounting a support frame 1B for the driver's seat of a frame type tractor on a vehicle body frame so that the weight of an operator seating on the driver's seat is prevented from acting upon the transmission casing. CONSTITUTION:In a tractor in which a prime mover including an engine 1 is mounted on the front section of a vehicle body frame 1, and a wheel drive casing section 8 consisting of a transmission casing 8A and a right and left axle casing 8B is mounted on the rear section of the vehicle body frame 1, the vehicle body frame 1 has a support frame 1B for the above-mentioned casing section 8, which is formed of an inversed U-like cross-sectioned shape main frame 17. An axle casing support section 30 is welded to both lateral side sections of the rear end part of the main frame 27 in such a condition that the support frame 30 abuts, from above, against a pair of front and rear plate-like parts 29 which are integrally incorporated with the axle casing 8B. Further, a foot rest step is secured to the front end side lower section of the support frame 1B with the use of bolts, and as well, a plate-like support frame 36 for a driver's seat 13 is arranged between right and left rear wheel fenders 35 and is secured thereto with the use of bolts.

化並びに簡素化を充分に図シ難いものであった。Car tractors are designed so that the ground reaction force and the weight of the machine act on the left and right axle cases, and prevent large loads from acting on the transmission case for wheel drive. The overall structure was made lighter and simpler, such as by making the transmission case thinner and lighter, and by making it unnecessary to increase the strength of the connection between the transmission case and the axle case. However, in the past, the driver's seat was replaced by the wheel drive transmission case, making it difficult to sufficiently reduce the weight and simplify the overall structure.

りｆｃ。In other words, according to Jubeikaga, the weight of the seated worker acts on the wheel drive transmission case as a dynamic load due to the vertical vibration of the aircraft, so the strength of the transmission case increases.
Also, it is not possible to sufficiently weaken the connection strength between the transmission case and the axle case, so there is room for improvement.

A simple modification to accommodate # on the vehicle body frame side can suppress the weight of a seated worker from acting on the transmission case for wheel drive, making the transmission case even lighter. All-layer connection structure with case! Since it can be made into a plain piece,69 it has resulted in a frame-type tractor that can be used more conveniently.
