2. Description of the Related Art A conventional differential limiting mechanism is broadly divided into a system that blocks differential gears as necessary to prevent differential operation, and a rotational difference causes a drag force depending on the rotational difference. It can be classified into two methods, that is, a method of limiting the generated rotation difference within a certain range, but in the case of the block method, switching is required each time, and in the case of a method in which a drag force is generated due to the rotation difference, the differential function is impaired and the operation performance is impaired. There were problems such as a decrease and a loss of fuel efficiency.

[Means for Solving the Problems] The rotation difference between wheels during traveling of a four-wheeled vehicle is the rotation difference between the inner and outer wheels and between the front and rear wheels, which occurs mainly during turning during normal traveling. The maximum rotation difference occurs when turning with the minimum radius of gyration. Although it depends on the vehicle type, the ratio of the number of rotations between the left and right driving wheels in a rear-wheel drive vehicle is about 3: 2 when turning with a minimum turning radius. In the case of a four-wheel drive vehicle, the ratio of the number of rotations between the front and rear wheels is about 5: 4. Therefore, the rotation difference between the left and right side gears of the differential device is mechanically adjusted to be 3: 2 to 2: 3.
If the rotation difference is less than 3: 2, the differential function is not limited at all, and if the rotation difference exceeds 3: 2, the function of the differential function is limited. In this case, since the differential function is not limited at all during normal traveling, the operation function does not deteriorate. Also, when the wheel on one side spins due to slip or the like, the differential function is limited because the rotation ratio exceeds the range of 3: 2, the driving force is transmitted to the wheel on the other side, and escape from the slip state occurs. It is possible.

Hold the rotation equal to (2-b). When the rotations of the left and right side gears are different due to turning or the like and the rotation speeds of the gears (3) and (4) are different, for example, when the rotation speed of the gear (3) is higher than the rotation speed of the gear (4) Ring gear (1-
g) rotates in the same direction as (3) and (2-g) rotates in the opposite direction to absorb the rotation difference between (3) and (4). The difference in the rotation ratio between the left and right drive wheels caused by a normal driving operation such as turning becomes the maximum when turning with the minimum turning radius. Therefore, if the differential limiting function is activated only when the difference in the rotation ratio becomes larger than the difference in the rotation ratio caused by turning at the minimum turning radius, the difference in rotation between the left and right drive wheels is not limited in normal driving operation. A differential limiting mechanism is configured so that the differential limiting function is activated when a wheel on one side spins without adding anything.

When the difference between the left and right rotational ratios exceeds a certain range due to idling on one side, a function of limiting the rotational difference within a certain range works, but this is due to the ring gear (g) and the sun gear (a). It is presumed that this is due to the action of the non-backflow mechanism formed during the period. The non-reverse flow mechanism generally seen is found between the drive shaft and the driven shaft of the speed reduction mechanism, but the differential mechanism used in the present invention is the same mechanism when the sun gear (b) is fixed. Is configured. In this case, whether the non-backflow phenomenon occurs or not depends on the value of the gear ratio N 2 between the gears (a) and (b), that is, If the value of the gear ratio at which the reversible flow shifts to the non-reverse flow is K, the differential mechanism of the present invention requires the non-reverse flow structure.
The gear ratio between (a) and (b) is within the range of the following equation. The maximum value of the difference is 3: 2, and if the rotational difference between (1-a) and (2-a) exceeds 3: 2, the force that tries to keep the rotational difference within 3: 2 will work. Will be transmitted. When the rotation difference is smaller than 3: 2, the rotation difference can be absorbed by the rotation of the ring gears (g-1) and (g-2), so that no drag is generated between the gears (3) and (4). Smooth rotation is performed.

(1) During normal driving operation, for example, when turning, the differential limiting function does not work at all, so that the operability is excellent and the loss of fuel consumption is small. (2) In order to limit the rotation ratio of the left and right side gears of the differential device to within a certain ratio, when the drive wheel on one side slips, the differential limiting function works when the left and right rotation ratios exceed the limit range. The driving force is transmitted to the wheel on the opposite side of the existing wheel. Since the differential limiting action works as a mechanical action, it is possible to transmit a sufficient driving force to the driving wheels with little loss due to idling on one side. (3) In the case of the conventional method in which the differential limitation is performed by using the reaction force generated due to the difference in the number of rotations, the driving force transmitted to the opposite side of the idling wheel is proportional to the amount of the difference in rotation, and thus the low speed operation is performed. However, in the case of the present invention, the differential limiting effect works when the ratio of the left and right rotation speeds exceeds a certain range, so that sufficient driving force can be transmitted even at low speed operation. it can.

A) Between the gears (a) and (b) so that the ring gear (g) and the sun gear (a) have a non-reverse flow structure when the sun gear (b) is fixed by the differential gear device of (a). Gear ratio The value is set to be larger than 1. C) A pair of differential gear units composed of a and a, a differential gear unit (1) and a differential gear unit (2) are provided on the main shaft (9) so as to be symmetrical to each other, and the sun gear ( 1-b)
Gears (3) and (4) provided by connecting (2-b) to (1-a) and (2-a) are used as input / output gears. D) Replace the ring gear (1-g) (2-g) with the gear (5)
(6) Connected via (7) and (8), the rotation of one ring gear is transmitted as the rotation of the other ring gear in the opposite direction. The differential limiting device configured as described above is capable of freely changing the rotation ratio between the input / output gears (3) and (4) within a certain range, but limiting the change of the rotation ratio exceeding the certain range.
