[Prior Art] % % The ' differential' is a device that is set to cope with the different rotational speeds of the two wheels when the vehicle is turning. The early differential was a simple mechanical constructor. It was mainly connected by the two planetary helical gears to the side gears of one side axle to withstand the different rotational speeds of the side gears during the turning; that is, what the two wheels hit? When the ground environment is rotated at different speeds, the differential only has a passive fit and cannot limit the rotation of the axle. Therefore, if the single wheel is slipped due to slippery ground or a single wheel suspension, the other wheel will also lose the driving force at the same time. Therefore, the device of the limited slip differential was later used to make the wheel body not to idling or to lose power. There are many types and configurations of the limited-slip differential, and there are mechanical types that use the clutch to reach the limit of π; there is a torque-sensing type that uses the friction generated by the combination of the helical gears to exert the limited-slip effect; A combination of clutch plates, through the injection of Shi Xi oil (with viscous, high-temperature expansion characteristics), the left and right axles produce a difference in rotation, and then the viscous coupling of the oyster oil is used as a viscous coupling. However, the limited slip differentials currently known are complicated in construction. It is not easy to maintain and repair, and the lack of a wide range of speeds can be used. It is a defect in the use of power. Therefore, how to develop and design a simple structure and convenient maintenance. And the limited slip effect is indeed effective, and the limited slip 4 differential that acts when the differential range is small is actually an urgent need for driving safety. SUMMARY OF THE INVENTION In view of the above urgent needs, the present inventors have intensively conceived research and development creations, and have worked hard for a long time. The main purpose of this month is to provide a limited slip differential that is easy to construct and easy to maintain. In addition, the other main county of the present invention provides a limited slip differential which can be used in the differential speed hour, that is, the limited slip function. A. The invention has to be secretly provided for the age-slip differential speed S, which limits the rotation speed of the planetary helical gear in the differential by the hydraulic current limiting principle, thereby achieving the effect of limiting slip. In order to achieve the above purpose, the differential gear of the present riding design is driven by a drive gear connected to the end of the drive shaft to drive the ring gear of the spit ring, and the inner side of the wheel is rotated, and the gear rotates synchronously. At least - bribe star helical gear storage, the at least one _ planetary helical gear complex and the other - symmetrical weaving wheel _; the side gears are respectively connected to one wheel axially two sides protruding; and the at least one planetary helical gear The axis is deepened inside and fixed to the driving gear side step lion, and the main _ wheel is connected to the belt from the Helmet; the oil is injected into the space where the main and driven discs coexist, so that the same When the main and driven teeth rotate, the oil will be driven to pass through the gap between the end faces of the main and driven gears. Therefore, the fans will pass through the bribes; the obstacles generated by the easy passage will be the main gears. 5 Coaxial core, planetary oblique recording and instrument wheel can not rotate quickly, (10) The second axle produces a limited effect. 1331574 In the above-mentioned limited county speed H towel, the fiber-optic helical gear of the fresh fiber wheel is suitable for three. In the above-mentioned limited slip differential, the axial centers of the three planetary helical gears sprayed between the side gears are fixed to each other after the depth of the field, and the two are driven by the driven gears. The rotation is driven; when the main and driven gears are rotated by the main and driven gears, the oil is driven to pass through the gap between the end faces of the main and driven gears. [Embodiment] In order to achieve the above object, the present invention achieves the above-mentioned technical means and the effect of achieving the same, and the following can be fully explained in conjunction with the detailed explanation of Guanqi.

The limited-slip differential 1G is rotated by a drive gear (1) connected to the drive end, and the ring gear 12 with the action 90 is rotated. The ring gear 12 is driven on the inner side - the side gear 13 is two steps, the side gear (3) That is, the axle 13 is gorge; the side gear (3) is rotated by the three planetary helical gears 21, 22, 23, and the planetary helical gears H 23 are symmetrical to the other side of the side record 131 and the other side. One = , that is, the knitting wheel (3), (4) is at the same time with the middle of the M, 23, the rugged; the face _ the axis Z, the axis 211 of the planetary helical gears 21, 22, 23, the winter 23 is the wall 6 1331574 • * Supporting positioning and free to rotate, and the axes 2Π, 22 231 are deep inside and then fixed to a driving gear 212, 222, 232 for synchronous rotation; the driving gears Μ, 222 And 232 are respectively engaged with a side driven gear 213, a cut 233, and 233 to drive the rotation, and then injected into the space where the driving gears 212, 222, 232 and the driven gears 2, 223, 233 coexist. Oil. Therefore, when each group of master and driven gears 212, 213 (as shown in the second figure) or 222, 223 ' or 232, 233 rotates, the oil will be driven from the main and driven tei wheels 212, 213, 222, 223; The gap between the end faces of 232 and 233 passes, and if the gap between the % and the gap is smaller, the oil is less likely to pass quickly. Therefore, it is difficult to quickly pass the blockage caused by the gap between the end faces of the main and driven gears 212, 213; 222, 223; 232, 233. Turning into the drag force of the main and driven gears 212, 213; 222, 223; 232, 233; that is, using the principle that the oil cannot pass quickly, causing the main and driven gears 212 213 ' 222 223, 232, and 233 cannot be rotated quickly, so that the shafts 211, 221, 231 and the planetary helical gears 21, 22, 23 and the meshed side gears 13 and 141 cannot be rotated rapidly to generate a differential speed. The function of the device 1 is limited to slip. • Therefore, as long as the gap between the end faces of the main and slave gears 212, 213, 222, 223, 232, and 233 causes a blockage in which the oil cannot pass quickly, it is a limited slip. Therefore, even if a single wheel produces slippage, in the case where the axle of the wheel cannot rotate rapidly (ie, limited sliding action), the other wheel still has power, and can quickly leave the dilemma to reduce the dangerous phenomenon. The main and driven gears 212, 213; 222, 223; 232, 233 are capable of limited sliding function as long as one group exists, and the design of the three groups is separated by 12 〇 <> Balanced and designed 'but not limited to three groups. 7 1331574 It can be seen from the above description that in the case that the structural components of various limited slip differentials are quite complicated, the present invention is only on the coaxial 21, 22, 231 of the planetary helical gears 21, 22, and 23 The driving gears 212, 222, and 232 are internally connected, and each of the driven gears 213, 223, and 233' is coupled to the main and slave gears 212 and 213; 222 and 223; 232 and 233 respectively form a set of speed limiting. When the gear pump rotates, the oil can be driven by the gap between the end faces. Therefore, in the case of (4) (design) clearance, the oil can not pass smoothly when the main and driven gears rotate at high speed, resulting in the master, The drag force of the driven gear rotates to limit the maximum speed of the _ Park Star helical gear, but the oil system can pass smoothly when the main and driven gears are not rotating at high speeds, so the normal function of the differential is not affected. Such a simple structure can produce a true limited slip effect. / R riding a field to know the various money-sliding rides, and there is a report
