この発明は、左右の車輪が一定の角度だけ差動したのち
は、突子と突子との係容゛で確実に差動を阻止するノン
スリップデフを廉価ニ提供するものである。[Detailed Description of the Invention] The present invention provides an inexpensive non-slip differential that reliably prevents the differential movement by engagement between the protrusions after the left and right wheels have differentially moved by a certain angle. It is something.
通常の差動装置は、片側の車輪が増速すると、他の側の
車輪がその分だけ減速して、車輌を円滑に旋回させる。With a normal differential, when one wheel speeds up, the other wheel slows down by that amount, allowing the vehicle to turn smoothly.
しかし、片側の車輪がぬかるみに落ちるなど、抵抗が少

。However, if the resistance becomes too low, such as when the wheels on one side fall into the mud, only the wheels on that side will spin, and the wheels on the other side will not rotate at the same time, making it impossible for the vehicle to move forward. Various differential devices have been proposed to solve this problem, but since they use frictional force, they are unstable in terms of effectiveness and start, and also cause differences due to wear, so they are not sufficient.

的であった。In comparison, according to the present invention, after the differential gear or the binion gear has slid against the differential gear by a predetermined angle, the protrusions engage with each other and the slider does not slide at all. Since the differential does not occur, the differential can be reliably stopped, and the configuration is extremely simple.
It was particularly effective for use in the front wheels of rice transplanters and other agricultural machinery.

転させている。(6) a is a narrow protrusion provided on the outer surface of the differential gear (6), and a discontinuous arc-shaped groove (4) b is provided on the inner surface of the differential gear (4). The protrusion (6) a and the arc-shaped groove (4) b are fitted into the groove (4) b. Since this differential device is configured as described above, the power of the prime mover (1) is transmitted through the bevel gear (8). side gear (4
) and rotates this and the support (5), and when the resistance of the left and right wheels is equal, the resistance between the side gear (4) and the differential gear (6), and between the support (5) and the pinion ■ The output shafts (8) and (9) are rotated at the same speed without any rubbing.

間の差動が停止する。Here, when the resistance forces on the left and right wheels become different, the output shaft (8) on the side with smaller resistance becomes the output shaft (9) on the side with larger resistance.
The speed is increased by the amount that the rotational speed of the output shaft (9) has decreased. Then, rubbing occurs between the inner surface of the side gear (4) and the outer surface of the differential gear (6), and the protrusion 0) moves in the groove (b) b, causing an engagement conflict with the protrusion (0). ÷ base, the sliding of both stops, and from then on each output shaft (8) (9)
The differential between them stops.

特徴がある。This is essential! In particular, the present invention includes a differential case driven by an input shaft (1), and a pair of projecting shafts (8) (9) that project from the differential case to the left and right to transmit power to the left and right wheels.
The differential gear (6 bar γ) fixed to each of the output shafts (8) and (9) in the differential case is interlocked with the pinion gear αΦ, and the differential gear (6) or the differential case and the pinion are connected to each other. A gear (14) is a differential gear that is engaged with a protrusion (4) o and a protrusion (6) a so that the gear (14) slides for a certain period of time and then locks and rotates together. Because it is a device, it has an extremely simple configuration and can be provided at a low price, as well as being able to reliably prevent differential movement after differential movement within a predetermined range, making it possible to obtain an optimal differential device for the front wheels of rice transplanters. There are characteristics that can be used.
