[Industrial Application Field] The present invention relates to a rear wheel torque distribution control device for two rear wheels that automatically controls the torque distribution between the left and right rear wheels as a measure for steering stability and turning performance during steering. , Final area '4! This is related to the transmission structure of the section. [Prior art] Conventionally, front engine/rear drive (FR)
In a vehicle that drives the rear wheels, such as a car or a four-wheel drive (4WD) vehicle, power is transmitted from the transmission output side to the left and right rear wheel drive shafts via a differential device. Therefore, when the 11 cars turn, the difference in rotation between the inner and outer wheels is absorbed, allowing them to turn smoothly. In addition, by adding a differential limiting device to the differential, the driving force of the left and right wheels becomes unequal based on the difference in rotational speed of the left and right wheels, so that the driving performance of the vehicle is different from that of a vehicle without the differential limiting device. Some did.

By the way, in the above conventional technology, the moon! Since the difference in rotation between the inner and outer wheels is simply absorbed during both turns, it is not possible to improve driving stability or improve turning performance during turns. In addition, in the case where a differential limiting device is added, a difference in driving force between the left and right wheels occurs only after a difference in rotational speed between the left and right wheels occurs, such as during cornering, which causes a difference in driving performance.
Since it is generated passively like Ha, this motion performance is not necessarily desirable. Therefore, the present invention not only enables smooth turning by absorbing the difference in rotation between the inner and outer wheels, but also improves turning performance and the stability of turning. One object of the present invention is to provide a rear wheel torque distribution control device for a vehicle that can be made smaller and slimmer.

The τ1η end of [ is supported by a bearing 24 on the flange portion 7a of the shaft 7, and the rear end is supported by a bearing 26 of a bearing case 25 screwed to the case 20. A plate 28 is disposed between the drum 23 and the hub 27 spline-coupled to the output shaft 9R, and the piston 30 of the hydraulic air 29 is connected to the plate 28 by a leaf spring 31.
The hydraulic clutches 8R are arranged opposite to each other with a pressure plate 32 interposed therebetween. Further, a hollow output shaft 9L is coaxially provided on a part of the output shaft 9R and supported by a bearing 33 of the case 20, and a plate is connected between the drum 23 and a hub 34 spline-coupled to the output shaft 9L. 35, the hydraulic air 36 as described above.
The screw 31 is the leaf spring 38. pressure blade 4
The hydraulic clutches 8L are arranged opposite to each other via 7. A bearing case 39 is attached to the left side of the case 20, and supported by a bearing 40 of this case 39, the axle 11L is installed at right angles to the left side. A large-diameter ring gear 41 of the final gear 101- is spline-coupled to the center shaft 11L, and a drive pinion 42 at the rear end of the output shaft 9L meshes with the ring gear 41. A bearing case 43 is also attached to the right side of the case 20 at a position slightly rearwardly shifted from the jii +Ii+ 111-, and supported by the bearing 44 of this case 43, the axle 11R is installed at right angles to the right. And 7 final gear 1 on center shaft 11R
The 0R ring gear 45 is attached to the ring gear A741 by spline connection, and the output shaft 9
A drive pinion 46 is attached to the rear opposite to the pinion 42 of R, and the ring gear 45 and the drive pinion 46 mesh with each other. Next, the operation of the rear wheel torque distribution control device configured as described above will be explained. First, the power input from the transmission output horn shaft 5 to the rear drive shaft 7 is transmitted to the output shafts 9L, 9R according to the transmission torque of the hydraulic clutches 8L, 8R, and is further decelerated by the final gears IOL, 10R. The axle is 11L. The power is transmitted to the rear wheels 11R and left and right rear wheels 12L and 12R. Therefore, to explain an example of torque distribution in this case, vehicle speed sensor height 15 and steering angle sensor 1G No. 4R are input to the control unit 17, and these sensor signals determine whether the vehicle is traveling straight, turning at medium-low speed, or turning at high speed. Detected. and,
When traveling straight, the hydraulic pressures of actuators 13L and 13Rk:J and hydraulic clutches 8L and 8R are controlled and transmitted in the same manner.
1- Lubrication distribution becomes rough, left and right rear wheels 121.12R
are driven with the same torque. When turning at medium to low speeds, the torque distribution is controlled so that the torque is distributed more to the inner wheels than to the outer wheels. That is, when turning to the left in FIG. 1, the oil pressure of the hydraulic clutch 8L is set to be small, and the oil pressure of the hydraulic clutch 81< is set to be large, thereby causing the left and right rear wheels 121-. The driving torque of 12R is as shown by the solid line. In this way, the inner left rear wheel 121 rotates at a low speed due to the slip of the hydraulic clutch 8L, and the differential function similarly absorbs the difference in rotation between the inner and outer wheels to enable smooth turning. J: In the above torque distribution, the solid line J is at the vehicle center of gravity G, and the reverse time t1 is
This generates a moment in the same direction as the moment due to the cornering force indicated by the dashed line, improving turning performance. On the other hand, when turning 10 at speed B, the torque distribution is controlled to be larger on the inner wheels than on the outer wheels, contrary to the above description. Therefore, for example, in the left turn described in "-", the left and right rear wheels 12L, 1
The torque of 2R is as shown by the dashed-dotted line, and a moment is generated in the clockwise direction at the center of gravity G as shown by the dashed-dotted line.
It acts to eliminate one moment due to cornering force as shown by the broken line. Therefore, stability during turning is improved. Although one embodiment of the present invention has been described above, the front hydraulic clutch may be configured to be transmitted to the left rear wheel, and the rear hydraulic clutch may be configured to be transmitted to the right rear wheel. [Effects of the Invention] According to the present invention, the rear wheel torque distribution is controlled in the turning state, so the 1R at medium and low speeds is controlled.
The turning performance of 11) and the stability when turning at high speed [<j1] can be improved to an appropriate level.Since it is a combination of two sets of hydraulic clutches and final gear 7, a differential gear is not required. This makes the flight simpler, and compared to when steering the rear wheels, 1,100 meters are placed in the cylinder.Since the hydraulic clutch is placed on the input side of the final 1'N?, the clutch chamber becomes smaller, making it more compact. Since the rt of the device is approximately the same as that of a conventional differential device, there is no need to increase the joint angle of the axle.
