Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gearboxes, in particular to a bevel gear differential and gearbox integrating slip-limiting and decoupling functions. BACKGROUND

[0002] Some vehicles on the market may need to add new functions to eAxle (electric drive system), such as adding disconnection function. For example, as an auxiliary drive device of a four-wheel drive vehicle, it needs to be disconnected when the auxiliary drive device does not participate in driving to reduce resistance loss and improve vehicle efficiency. The closer the disconnection position is to the wheel, the higher the efficiency, for example, it can be disconnected at the differential or half shaft position; for adding slip-limiting function, when the vehicle is driving on a wet road, if one wheel slips, due to the presence of the differential, the torque of the other wheel will also be very small, causing the vehicle to slip and unable to move. For sports cars, customers usually require to add slip-limiting function, when the vehicle is in trouble, the differential function needs to be blocked to output torque to the wheels to complete the escape.

[0003] There are also gearbox solutions integrating slip-limiting and decoupling functions in the prior art.

[0004] In patent CN221097375U, the connection, disconnection state between the differential housing, half shaft gear and half shaft is controlled by a sliding sleeve (tooth sleeve part) to realize differential, slip-limiting and decoupling functions. When the differential housing and the second tooth part are in the disconnected state, and the second half shaft gear and the second half shaft are in the connected state, the normal differential function is realized. When the differential housing, the second tooth part and the second half shaft are connected at the same time, the slip-limiting function is realized. When the second half shaft and the second half shaft gear are disconnected, the decoupling function is realized.

[0005] In patent CN115711281A, the slip-limiting and decoupling functions are integrated into the differential, which includes a transmission electromagnetic actuator to control the connection (circumferential fixation) and disconnection between the housing and the planet carrier; a differential electromagnetic actuator to control the connection and disconnection between the housing and the left half shaft gear. By connecting the housing and the planet carrier, and disconnecting the housing and the left half shaft gear, the normal differential function can be realized; by connecting the housing and the planet carrier, and connecting the housing and the left half shaft gear, the slip-limiting function can be realized; by disconnecting the housing and the planet carrier, and disconnecting the housing and the left half shaft gear, the decoupling function can be realized.

[0006] However, the above-mentioned solutions have room for improvement.

[0007] For the way of using an additional module (as shown in patent CN221097375U) to obtain decoupling and limited slip functions, although the original differential structure remains unchanged, the added sliding sleeve and other components increase the axial length of the gearbox, which is not conducive to the layout of the gearbox in the vehicle. In addition, the disconnection on the half shaft makes the speed difference between the two output sides of the differential very large, resulting in differential burning and NVH (noise, vibration and harshness) problems.

[0008] For the way of using a highly integrated structure (as shown in patent CN115711281A) to realize decoupling and limited slip functions, although the structure is compact, it is difficult to control the two electromagnetic actuators separately, and there is a functional safety risk. Failure of any of the two electromagnetic actuators will result in loss of function. The planetary gear carrier is supported in the differential housing. Due to the large radial size of the planetary gear carrier and the limited space between the planetary gear carrier and the differential housing, there is no bearing support between them, so a high wear-resistant coating is needed, and there is still a risk of wear, and the support stiffness is poor.

[0009] In addition, the structure of the differential housing is complex and can only be cast, which may have casting defects and low strength problems. A heavy differential housing is needed to ensure strength, resulting in a large size and weight of the differential housing. In order to ensure installation, the differential housing needs to be connected to the final driven gear (housing drive gear) by bolts, and the friction force generated by the fastening bolts is used for torque transmission. Therefore, the torque transmission capacity of the differential is limited by the size of the final driven gear and the number of bolts. If the diameter of the final driven gear is small, the bolt distribution circle will be smaller, the number of bolts will be reduced, and the transmitted torque will also be reduced. In addition, in the oil environment of the gearbox, in order to ensure the locking force of the bolts, bolts with expensive coatings need to be used and cannot be reused; due to structural limitations, the differential housing cannot be designed symmetrically and cannot share a mold.

[0069] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0070] This application provides a bevel gear differential (hereinafter, sometimes referred to as "differential") and a transmission with integrated limited-slip and decoupling functions.

[0071] See Figure 1 , Figures 8 to 11 The differential may include a planetary gear carrier 100. The planetary gear carrier 100 may contain meshing planetary gears 110 and half-shaft gears 120, and the planetary gears 110 may be formed as bevel gears.

[0072] The differential may also include an inner housing 200. The planetary gear carrier 100 may be fixedly connected to the inner housing 200, so that power can be transmitted to the planetary gear carrier 100 through the inner housing 200.

[0073] The differential may also include a housing 300 and a ring gear 400 (the input gear of the differential, which may also be referred to as the final reduction gear). The inner housing 200 and the planetary gear carrier 100 are rotatably mounted in the housing 300, and the ring gear 400 is fixedly connected to the housing 300. External power can be transmitted to the housing 300 through the ring gear 400.

[0074] The differential can further include a sliding sleeve 500, which can include at least a sliding sleeve first contact portion 510 and a sliding sleeve second contact portion 520 fixed in a circumferential direction. Here, in one example, the sliding sleeve first contact portion 510 and the sliding sleeve second contact portion 520 can be integrally formed. The sliding sleeve first contact portion 510 is connected to the outer shell 300 in a circumferential direction. The outer shell 300 and the inner shell 200 are provided with a sliding sleeve opening (outer shell sliding sleeve opening 310, inner shell sliding sleeve opening 210), and the sliding sleeve second contact portion 520 is configured to be axially movable to adjust the degree of extension into the sliding sleeve opening. For example, the sliding sleeve second contact portion 520 can:

[0075] (1) Only the outer shell 300 is connected, so that the power of the ring gear 400 is only transmitted to the outer shell 300. At this time, the power is not transmitted internally, the outer shell 300 connected to the power source and the half shaft gear 120 connected to the half shaft are in a disconnected state, and the differential plays a decoupling function, as shown in Figure 1 .

[0076] (2) Only the outer shell 300 and the inner shell 200 are connected at the same time, so that the power of the ring gear 400 is transmitted to the planet carrier 100. At this time, the power is normally transmitted to the planet carrier 100, the ring gear 400 and the planet carrier 100 rotate synchronously, and the differential normally plays a differential function, as shown in Figure 2 .

[0077] (3) The outer shell 300, the inner shell 200 and the half shaft gear 120 are connected at the same time, so that the ring gear 400, the planet carrier 100 and the half shaft gear 120 rotate synchronously. Based on the principle of the reducer, the rotational speeds of the two half shaft gears are the same, so the limited slip function is achieved, as shown in Figure 3 .

[0078] The axial sliding position of the sliding sleeve 500 can be controlled only by one actuator (not shown in the figure) to achieve the function switching of the differential. Compared with the two electromagnetic actuators mentioned in the background art, it is simpler.

[0079] The decoupling of the present application is achieved by disconnecting the outer shell 300 and the inner shell 200, which overcomes the problem that the speed difference between the two output sides of the differential is large, which leads to the burning of the differential and the NVH problem.

[0080] In one embodiment of the present application, referring to Figure 6 , the sliding sleeve first contact portion 510 can be formed as an annular sleeve, which is spline-connected to the outer circumferential surface of the outer shell 300. The annular sleeve can be fixed in the circumferential direction with the outer shell 300, and can slide relatively in the axial direction.

[0081] Further, the length of the sliding sleeve 500 is set such that when the sliding sleeve second contact portion 520 is connected to the outer shell 300 only, the sliding sleeve 500 is located within the end face of the outer shell 300 in the axial direction (does not exceed the outer shell 300), which does not increase the axial dimension of the gearbox, and is conducive to the space layout of the vehicle interior.

[0082] Further, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 , the outer peripheral surface of the outer shell 300 can be provided with a positioning pin 600, and the annular sleeve includes a first positioning groove 511, a second positioning groove 512 and a third positioning groove 513 arranged along the axial direction of the outer shell 300. In the radial direction of the outer shell 300, the pin head 610 of the positioning pin 600 can elastically abut against the annular sleeve. When the sliding sleeve 500 is pushed to the position for corresponding functions (decoupling, normal differential, limited slip), the pin head 610 of the positioning pin 600 just abuts against the corresponding positioning groove.

[0083] For example, referring to Figure 1 , when the pin head 610 is located in the first positioning groove 511, the sliding sleeve second contact portion 520 is connected to the outer shell 300 only, corresponding to the decoupling function.

[0084] Referring to Figure 2 , when the pin head 610 is located in the second positioning groove 512, the sliding sleeve second contact portion 520 is connected to the outer shell 300 and the inner shell 200 simultaneously, corresponding to the differential function.

[0085] Referring to Figure 3 , when the pin head 610 is located in the third positioning groove 513, the sliding sleeve second contact portion 520 is connected to the outer shell 300, the inner shell 200 and the half shaft gear 120 simultaneously, corresponding to the limited slip function.

[0086] Further, the positioning pin 600 and the positioning groove can be arranged in multiple circumferential directions to increase the position fixing effect. Of course, when the sliding sleeve 500 is controlled to slide in the axial direction, the spring in the positioning pin 600 will be compressed, so that the sliding sleeve 500 can slide in the axial direction.

[0087] In an embodiment of the present application, referring to Figure 6 , the sliding sleeve second contact portion 520 can include a plurality of struts 521 arranged in the axial direction of the outer shell 300 and arrayed in the circumferential direction. Referring to Figure 1 、 Figure 4 、 Figure 5 , the inner shell 200 can include a plurality of inner shell sliding sleeve openings 210 arranged in the circumferential direction, and the outer shell 300 can include a plurality of outer shell sliding sleeve openings 310 arranged in the circumferential direction, and the struts 521 can extend into the outer shell sliding sleeve openings 310 and the inner shell sliding sleeve openings 210.

[0088] Further, referring toFigure 1 、 Figure 8 The circumferential surface of the half axle gear 120 can be provided with engagement teeth 121, and when the strut 521 extends into the position of the engagement teeth 121 (i.e. the tooth gap between the engagement teeth 121), the engagement teeth 121 can be fixedly connected together with the strut 521 in the circumferential direction. It should be understood that the engagement teeth 121 can include protruding teeth which can be welded or formed on the outer circumferential surface of the half axle gear 120.

[0089] In an embodiment of the present application, referring to Figure 4 The inner shell 200 can include a first inner shell 201 and a second inner shell 202 which are at least partially structurally symmetrical. Exemplarily, the inner shell sliding sleeve opening 210 can be provided only on the first inner shell 201, and the second inner shell 202 can not be provided with the inner shell sliding sleeve opening 210. Alternatively, the inner shell sliding sleeve openings 210 can be provided on both the first inner shell 201 and the second inner shell 202, but only the inner shell sliding sleeve opening 210 of the first inner shell 201 is polished to facilitate the insertion of the second contact portion of the sliding sleeve 500. In this way, the first inner shell 201 and the second inner shell 202 can share a mold to produce the same blank part. The blank part has a simple structure and can be produced by stamping, which can reduce the wall thickness, size and weight of the shell.

[0090] Here, partial structural symmetry can refer to symmetry in overall shape, with only local details or features being different. At least partial structural symmetry includes complete symmetry.

[0091] Further, referring to Figure 1 The planetary gear carrier 100 can be welded between the first inner shell 201 and the second inner shell 202. Correspondingly, the planetary gear 110 and the half axle gear 120 are also located in the first inner shell 201 and the second inner shell 202.

[0092] Similarly, referring to Figure 5 The outer shell 300 can include a first outer shell 301 and a second outer shell 302 which are at least partially structurally symmetrical. The outer shell sliding sleeve opening 310 can be provided only on the first outer shell 301, and the second outer shell 302 can not be provided with the outer shell sliding sleeve opening 310. Alternatively, the outer shell sliding sleeve openings 310 can be provided on both the first outer shell 301 and the second outer shell 302, but only the outer shell sliding sleeve opening 310 of the first outer shell 301 is polished to facilitate the insertion of the second contact portion of the sliding sleeve 500. The outer spline for mating with the spline of the sliding sleeve 500 can be provided only on the first outer shell 301. The first outer shell 301 and the second outer shell 302 can share a mold to produce the same blank part by stamping, which can reduce the wall thickness, size and weight of the shell and reduce costs.

[0093] In an embodiment of the present application, referring to Figure 1The inner housing 200 is rotatably arranged in the outer housing 300 through the first bearing 710. The bearing support is good in rigidity, reliable in support, and ensures stable work of the system.

[0094] In an embodiment of the present application, referring to Figure 7 The ring gear 400 can be connected to the outer housing 300 through spline. Referring to Figure 1 The axial ends of the ring gear 400 can also be provided with a snap ring 410 to limit the axial outward displacement of the ring gear 400. The spline has high torque transmission capacity and is not limited by the size of the ring gear 400, and can be used for differentials of different torques. The form of the snap ring 410 allows the first outer housing 301 and the second outer housing 302 to be disassembled and assembled with the ring gear 400, without using fastening bolts, and the torque transmission is not affected.

[0095] The gearbox provided in the present application can include the foregoing cone differential with integrated limited slip and decoupling functions. The outer housing 300 can be rotatably arranged in the gearbox housing through the second bearing 720.

[0096] The above describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered within the scope of protection of the present application.
