[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] It should be noted that the drive shaft is an important component of the automobile transmission system. Its main function is to transmit the torque and motion transmitted by the transfer case to the reducer, and then transmit the torque and motion to the wheels through the main reducer and drive shaft to drive the wheels to move.

[0038] In the prior art, the universal joint of the front drive shaft is connected to the flanges of the transfer case and the front reducer on both sides by bolts / screws. In hybrid vehicles, the volume of the battery pack is closely related to the performance of the vehicle. Therefore, in order to make the hybrid vehicle have higher driving performance and to make more space for arranging the battery pack in the hybrid vehicle, the layout space of other structures will inevitably be compressed, such as: using a smaller transmission. As a result, the straight-line distance between the input flange of the front reducer and the output flange of the transfer case is shorter, and the layout space of the front drive shaft is insufficient, resulting in insufficient space for connecting the front drive shaft with the transfer case and the flanges of the front reducer on both sides. In addition, during the assembly process, the assembly tools will interfere with the drive shaft, making assembly relatively difficult and reducing production efficiency.

[0039] Therefore, starting from the structural design of the drive shaft, providing a solution to the above-mentioned problem, that is, providing a drive shaft with sufficient space for connecting the front drive shaft with the transfer case on both sides and the flange of the front reducer, and a relatively simple assembly process is a practical idea for the current hybrid vehicle design.

[0040] Reference below Figure 1-Figure 6 A transmission assembly 10 is described. The transmission assembly 10 of the utility model can provide sufficient space to facilitate the connection of the transmission shaft to the flanges of the transfer case and the front reducer on both sides, thereby simplifying the assembly process and improving the assembly efficiency.

[0041] The transmission assembly 10 according to the embodiment of the present utility model includes: an input shaft 101 , an output shaft 310 and a transmission member 200 .

[0042] It is understandable that during the construction of the vehicle, it is suitable to provide a transmission assembly 10 between the input shaft 101 of the reducer 100 and the output shaft 310 of the transmission 300. Since space needs to be made for the battery in hybrid vehicles nowadays, the layout space of other structures in the vehicle is small, so that there is insufficient space for arranging the transmission assembly 10, thereby affecting the assembly layout of the transmission assembly 10 in the vehicle.

[0043] Specifically, the input shaft 101 is connected to the reducer 100 ; the output shaft 310 is connected to the transmission 300 , and the output shaft 310 and the input shaft 101 are spaced apart; one end of the transmission member 200 is connected to the input shaft 101 , and the other end of the transmission member 200 is connected to the output shaft 310 .

[0044] Moreover, at least a portion of the input shaft 101 extends into one end of the transmission member 200 and is connected to the transmission member 200, and at least a portion of the output shaft 310 extends into the other end of the transmission member 200 and is connected to the transmission member 200. It should be noted that a transfer case may be integrated on the transmission 300 to make the structure of the transmission 300 more compact. In other words, the input shaft 101 is provided at the end of the reducer 100, and the transmission member 200 is used to connect the input shaft 101 and the output shaft 310, so that the transmission member 200 is suitable for transmitting the output performance of the transmission 300 to the reducer 100, so as to realize the assembly and use of the transmission assembly 10.

[0045] According to the transmission assembly 10 of the embodiment of the utility model, a transmission member 200 is provided between the input shaft 101 and the output shaft 310 so that the transmission member 200 connects the input shaft 101 and the output shaft 310, so as to realize power transmission between the input shaft 101 and the output shaft 310 through the transmission member 200. While realizing a more reliable connection between the reducer 100 and the transmission 300, the arrangement of the transmission assembly 10 can be made more compact to save space. At the same time, it can also avoid tool interference when fixing with bolts / screws due to the short relative distance between the output shaft 310 and the input shaft 101. The arrangement of the transmission member makes the assembly process of the transmission assembly 10 simpler.

[0046] In some embodiments, the transmission member 200 is configured as a hollow shaft, and the input shaft 101 and the output shaft 310 both extend into the transmission member 200 to be connected with the transmission member 200. It can be understood that by configuring the transmission member 200 as a hollow shaft tube, the overall weight of the transmission assembly 10 can be reduced, achieving a lightweight design while also reducing production costs.

[0047] In some embodiments, the transmission member 200 is provided with an internal spline, and the input shaft 101 is provided with an external spline, and the internal spline and the external spline are matched. It should be noted that the internal spline provided in the transmission member 200 is set through. Compared with the traditional method of assembling the transmission shaft by a flange, the transmission member 200 of this embodiment can make use of the sliding matching relationship between the internal and external splines to make the input shaft 101 slide and connect the transmission member 200, which greatly simplifies the assembly process and improves the assembly efficiency. In addition, the internal spline of the transmission member 200 can be constructed to penetrate the inner circumferential wall of the entire transmission member 200, which not only makes the structural setting of the internal spline more reliable, but also facilitates the arrangement of the internal spline inside the transmission member 200 and facilitates processing. At the same time, when the internal spline and the external spline are slidably matched, there is a sliding space, and at the same time, there can be a relative displacement between the reducer and the transmission, thereby increasing the service life of the transmission, and making the assembly of the transmission member 200 and the input shaft 101 more reliable; at the same time, it can adapt to more transmission distances of the input shaft 101 and the output shaft 310, improving the adaptability.

[0048] Moreover, the internal splines of the transmission member 200 and the external splines on the input shaft 101 are connected by sliding splines, so that the transmission member 200 and the input shaft 101 can be connected and power can be transmitted at the same time. In some specific embodiments, the transmission member 200 and the input shaft 101 can be pre-assembled to simplify the assembly process of the transmission assembly 10.

[0049] In other embodiments, the transmission member 200 and the input shaft 101 and the output shaft 310 can also be connected by strong magnetic connection to make the assembly connection process between the transmission member 200 and the input shaft 101 and the output shaft 310 simpler, and make the setting between the transmission member 200 and the input shaft 101 and the output shaft 310 more reliable, so as to improve the performance and service life of the transmission assembly 10.

[0050] In some embodiments, the transmission member 200 includes: an input section 210 and an output section 220 , the input shaft 101 is connected to the input section 210 , the output shaft 310 is connected to the output section 220 , and the input section 210 and the output section 220 are connected.

[0051] In this way, during the construction of the transmission member, the transmission member includes an input section 210 and an output section 220, the input section 210 is suitable for connecting with the input shaft 101, and the output section 220 is suitable for connecting with the output shaft 310, so as to realize the transmission setting of the transmission member 200 with the input shaft 101 and the output shaft 310.

[0052] In some embodiments, a transmission section 230 is further provided between the input section 210 and the output section 220 to connect the input section 210 and the output section 220. In this way, since a transmission section 230 can be provided between the input section 210 and the output section 220, so that the transmission section 230 is suitable for connecting the input section 210 and the output section 220, the power transmission between the input section 210 and the output section 220 is more reliable. At the same time, in some embodiments, the transmission section 230 can be set as a solid structure to make the power transmission more reliable. In other embodiments, the transmission section 230 can also be set as a hollow structure to reduce production costs.

[0053] In some embodiments, the input section 210 and the output section 220 are integrally formed to form an integrated transmission member 200. In this way, the input section 210 and the output section 220 are integrally formed, which not only saves production steps of the transmission member 200 and simplifies the production process of the transmission member 200, but also improves the connection strength between the input section 210 and the output section 220, and increases the structural strength of the transmission member 200, so that the use of the transmission member 200 on the transmission assembly 10 is more reliable.

[0054] In other embodiments, the input section 210 and the output section 220 are both split molded parts. That is, in order to facilitate the construction of the output section 220 and the input section 210 and make the structure of the output section 220 and the input section 210 more reliable, it is suitable to form the input section 210 and the output section 220 separately.

[0055] In some specific embodiments, the transmission member 200 further includes: a protective sleeve, which is arranged on the outside of the transmission member 200. That is to say, the transmission member 200 can be set as a hollow shaft tube. Setting the transmission member 200 as a metal transmission shaft can not only facilitate production, but also make the internal spline structure on the inner side of the transmission member 200 more reliable. At the same time, a protective sleeve is provided on the outside of the transmission member 200, and the protective sleeve is suitable for protecting the transmission member 200, so that the performance and service life of the transmission member 200 can be improved. In order to balance cost and performance, the transmission member 200 can be set as a metal transmission shaft, such as an iron transmission shaft, and the protective sleeve can be set as a protective sleeve made of PVC (polyvinyl chloride).

[0056] In some embodiments, the output shaft 310 is provided with a first clamping portion 301, and the inner side of the transmission member 200 is provided with a second clamping portion 203, and the first clamping portion 301 is clamped with the second clamping portion 203. It should be noted that in the process of connecting the output shaft 310 and the transmission member 200, an external spline is also provided on the output shaft 310, so that the external spline is spline-connected with the internal spline in the transmission member to achieve transmission. The first clamping portion 301 and the second clamping portion 203 are further provided between the output shaft 310 and the transmission member 200 to further fix the connection between the output shaft 310 and the transmission member 200, so that the transmission setting of the output shaft 310 and the transmission member 200 is more reliable.

[0057] It can be understood that, by providing the first clamping portion 301 on the transmission 300 to be clamped with the second clamping portion 203 on the inner side of the hollow shaft tube, the first clamping portion 301 and the second clamping portion 203 are clamped, so that the assembly connection between the transmission member 200 and the transmission 300 is more reliable, and the transmission setting structure stability between the transmission member 200 and the transmission 300 is higher. In some specific embodiments, in order to make the clamping process of the first clamping portion 301 and the second clamping portion 203 simpler and the clamping setting more reliable, it is suitable to set the first clamping portion 301 as a clamping hoop, and the second clamping portion 203 as a clamping groove, and the clamping hoop is clamped in the clamping groove.

[0058] In some specific embodiments, a magnetic middle portion is provided on the hollow shaft tube and fixed in the cavity of the hollow shaft tube; the middle portion is provided between the output shaft 310 and the input shaft 101, and a magnet portion that attracts the middle portion is provided on the input shaft 101 to facilitate the installation between the input shaft 101 and the hollow shaft tube, and also prevent the input shaft 101 from being separated from the cavity of the hollow shaft tube during the operation of the vehicle, so as to avoid a sudden interruption of power. A rubber layer is provided on the outer wall of the hollow shaft tube to isolate magnetic force, so as to prevent other substances from being adsorbed on the outer wall of the hollow shaft tube due to magnetic force.

[0059] In some embodiments, the transmission assembly 10 further includes: a limiting component 400. The limiting component 400 is provided on the outer side of the transmission member 200. By assembling the limiting component 400 to the end of the transmission member 200, the assembly process between the transmission member 200 and the reducer 100 and the transmission 300 is simplified, and the assembly setting between the transmission member 200 and the reducer 100 and the transmission 300 is made more reliable, so that the transmission member 200 can better transmit the output performance of the reducer 100 to the transmission 300, so as to improve the performance of the transmission assembly 10.

[0060] Specifically, in some embodiments, the limiting component 400 includes: a first connecting component 410 and a second connecting component 420, the first connecting component 410 is arranged between one end of the transmission member 200 and the input shaft 101; the second connecting component 420 is arranged between the other end of the transmission member 200 and the output shaft 310.

[0061] It is understandable that the limiting assembly 400 includes a first connecting assembly 410 and a second connecting assembly 420. The first connecting assembly 410 is arranged at one end of the transmission member 200 facing the input shaft 101, and the second connecting assembly 420 is arranged at one end of the transmission member 200 facing the transmission 300, so that the limiting assembly 400 can be connected to both ends of the transmission member 200 according to the design during the connection process, so that the assembly and connection process of the limiting assembly 400 is simpler and the connection effect is more reliable. At the same time, since the first connecting assembly 410 and the second connecting assembly 420 are respectively constructed at both ends of the transmission member 200, the positions can be distinguished during the assembly process of the transmission assembly 10, so that the assembly process of the transmission assembly 10 is simpler, so as to facilitate the subsequent disassembly for maintenance, so as to increase the service life of the transmission assembly 10.

[0062] In some embodiments, the first connecting component 410 and the second connecting component 420 both include: a connecting member 430 and a limiting member 440, and first connecting grooves 431 are provided at both ends of the connecting member 430; the limiting member 440 is arranged in the first connecting groove 431, and at least one first connecting groove 431 of the connecting member 430 is correspondingly arranged at the connection between the transmission member 200 and the input shaft 101. In this way, the first connecting component 410 and the second connecting component 420 both include: a connecting member 430 and a limiting member 440, and the connecting member 430 is suitable for being arranged between the transmission member 200 and the input shaft 101 or between the transmission member 200 and the transmission 300, so that the connecting member 430 can be arranged at both ends of the transmission member 200 so that the first connecting component 410 and the second connecting component 420 can be better arranged at both ends of the transmission member 200 to achieve the assembly connection of the transmission assembly 10, and a first connecting groove 431 is also provided at both ends of the connecting member 430, and the limiting member 440 is suitable for being arranged in the first connecting groove 431 to achieve the assembly connection of the limiting assembly. At the same time, in order to allow the limiting component 400 to be better limited and assembled at the end of the transmission member 200, the connecting members 430 in the first connecting component 410 and the second connecting component 420 are arranged so that one of the two first connecting grooves 431 on each connecting member 430 is correspondingly set at both ends of the transmission member 200 and respectively correspond to the input shaft 101 and the first connecting groove 431 on the connecting frame, so that the limit member 440 can be correspondingly set at both ends of the transmission member 200, so that the assembly process of the limiting component 400 is simpler and the assembly reliability of the limiting component 400 is improved.

[0063] In some embodiments, an elastic section 432 is provided in the middle of the connecting member 430, and the length of the elastic section 432 of the first connecting assembly 410 is greater than the length of the elastic section 432 of the second connecting assembly 420. It is understood that by providing the elastic section 432 on the connecting member 430, the first connecting assembly 410 and the second connecting assembly 420 can be assembled during the process of compression to provide space for the assembly connection of the transmission assembly 10, so as to make the assembly process of the transmission assembly 10 simpler. At the same time, in order to better distinguish the first connecting assembly 410 from the second connecting assembly 420, the length of the elastic section 432 of the connecting member 430 on the first connecting assembly 410 is greater than the length of the elastic section 432 of the connecting member 430 on the second connecting assembly 420, so that the assembly connection of the transmission assembly 10 can be achieved by compressing the connecting member 430 on the first connecting assembly 410 during the assembly process of the transmission assembly 10, so as to make the assembly process of the transmission assembly 10 simpler and more reliable.

[0064] In some embodiments, the transmission member 200 is provided with a second connection groove 201 at both ends, the connection member 430 is provided with a protrusion 433, and the first protrusion 433 is disposed in the second connection groove 201. In this way, during the assembly process of the connection member 430, the connection member 430 is suitable for being connected to the second connection groove 201 on the transmission member 200 through the protrusion 433, so that the first connection component 410 and the second connection component 420 are more reliably arranged on the transmission member 200, thereby improving the performance of the transmission assembly 10.

[0065] In some embodiments, the transmission shaft 200 is further provided with a groove 202, which is provided in the middle of the two second connecting grooves 201. In this way, by providing the groove 202 on the transmission shaft 200, the transmission assembly 10 is suitable for driving the hollow shaft tube to move through the groove 202 during the assembly process, so that the assembly process of the transmission assembly 10 is simpler and more reliable.

In this way, by providing a transmission member 200 between the input shaft 101 of the reducer 100 and the output shaft 310 of the transmission 300, so that the transmission member 200 connects the input shaft 101 and the output shaft 310, so as to realize the power transmission between the input shaft 101 and the output shaft 310 through the transmission member 200, while realizing the connection between the reducer 100 and the transmission 300 more reliably, the transmission assembly 10 can also be arranged more compactly to save space, so as to facilitate the design of the transmission system.

[0067] The vehicle according to the embodiment of the utility model comprises: the transmission system as described above. Thus, by arranging the transmission system as described above in the vehicle, since the transmission member 200 is arranged between the input shaft 101 of the reducer 100 and the output shaft 310 of the transmission 300, so that the transmission member 200 connects the input shaft 101 and the output shaft 310, so as to realize the power transmission between the input shaft 101 and the output shaft 310 through the transmission member 200, the connection between the reducer 100 and the transmission 300 is realized more reliably, and the transmission assembly 10 can be arranged more compactly to save space, so as to facilitate the design of the vehicle.
