Abstract
Description
Technical Field
[0001] This invention relates to the field of transmission technology, and in particular to a transmission and a vehicle. Background Technology
[0002] When a manual transmission vehicle encounters traffic congestion and needs to move forward in a stop-and-go manner, it often requires repeatedly pressing and releasing the clutch and shifting gears. The clutch, in particular, requires considerable force, and repeated operation can easily cause driver fatigue. While manual transmissions offer significant cost and fuel efficiency advantages and can satisfy some drivers' desire for a more engaging driving experience, automatic transmissions, although they can replace the clutch for gear shifting, are more expensive and lack the same driving feel.
[0003] In related technologies, the process of synchronizing the rotational speed of the gear shaft by synchronizing the sliding friction of the synchronizer ring is a semi-clutch process. It transmits a certain torque to force the rotational speed of both sides to be synchronized. However, since the synchronizer is designed to synchronize rotational speed, it does not have a large torque capacity. This operation usually causes the synchronizer to slip continuously and burn out the synchronizer. Summary of the Invention

[0033] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.
[0034] The following is for reference. Figures 1-8 The invention describes a transmission 100 according to an embodiment of the invention, and also proposes a vehicle.
[0035] The transmission 100 of this embodiment includes: a housing, an output shaft 30 and an input shaft 40, and a shifting structure. The output shaft 30 and the input shaft 40 are spaced apart within the housing. The input shaft 40 is connected to the engine for transmission, and the output shaft 30 is connected to the wheels for transmission.
[0036] The shifting structure includes a shifting device 10 and an interlocking device 20, both of which are located inside the housing.
[0037] Furthermore, the gear shifting device 10 includes a gear shift lever 21 and a plurality of gear shift slots. The plurality of gear shift slots are spaced apart from each other, and the gear shift lever 21 is engaged in any one of the gear shift slots. The plurality of gear shift slots include a D gear shift slot 23 and a first gear shift slot 22. The D gear shift slot 23 and the first gear shift slot 22 are spaced apart from each other, and the D gear itself does not output power.
[0038] Furthermore, the interlock device 20 is disposed on one side of the shifting device 10. One end of the interlock device 20 is selectively connected to the D-gear shift slot 23, and the other end is selectively connected to the first-gear shift slot 22. When the shift lever 21 is engaged in the D-gear shift slot 23, the interlock device 20 links the D-gear shift slot 23 and the first-gear shift slot 22, so that the output shaft 30 outputs power when the shift lever 21 is pushed. In other words, the interlock device 20 realizes the linkage between the D-gear shift slot 23 and the first-gear shift slot 22 under the drive of the shift lever 21. This allows the D-gear shift slot 23 to move forward when the shift lever 21 is pushed forward, and the forward movement of the D-gear shift slot 23 simultaneously drives the first-gear shift slot 22 to move forward, thereby enabling the transmission 100 to output power when no forward gear is engaged.
[0039] Therefore, by setting the interlock device 20, the linkage between the D gear shift slot 23 and the first gear shift slot 22 can be realized. When the shift lever 21 is pushed forward, the push lever drives the D gear shift slot 23 to move forward, which in turn drives the first gear shift slot 22 to move forward, so that the transmission 100 can output power when it is not engaged in a forward gear.
[0040] The first gear shift groove 22 includes a groove body 24 and a linkage part 25. The linkage part 25 is disposed on the groove body 24 and has an opening 29. When the shift lever 21 is engaged in the D gear shift groove 23, part of the interlocking device 20 is engaged in the opening 29 to link the D gear shift groove 23 and the first gear shift groove 22. In other words, the first gear shift groove 22 is composed of the groove body 24 and the linkage part 25, and the linkage part 25 is disposed on the groove body 24. Thus, when the linkage part 25 moves, it will drive the groove body 24 to move, thereby realizing the linkage between the D gear shift groove 23 and the first gear shift groove 22.
[0041] Furthermore, an opening 29 is provided on the linkage part 25, so that part of the interlocking device 20 can be fitted into the opening 29, thereby facilitating the linkage between the D gear shift groove 23 and the first gear shift groove 22.
[0042] Combination Figure 3 , Figure 5 and Figure 7 As shown, the first gear shift groove 22 also includes a lever 26 and a first elastic element 27. The lever 26 is fixed on the groove 24, and two annular protrusions are provided on the lever 26. The linkage part 25 is sleeved on the lever 26 and reciprocates between the two annular protrusions. The first elastic element 27 is sleeved on the lever 26 and abuts between the linkage part 25 and one of the annular protrusions. That is to say, the linkage part 25 and the lever 26 can also cooperate with each other through the first elastic element 27. In this way, when the shift lever 21 is pushed forward, the D gear can slightly exceed the travel of the first gear without affecting the first gear, so as to increase the positive pressure on the internal multi-plate clutch 43 and adjust the output torque.
[0043] Among them, the two annular protrusions form the up and down stroke of the linkage 25.
[0044] That is, by setting the first elastic element 27, the linkage 25 can be variable relative to the rod 26, thereby adjusting the output torque of the transmission 100.
[0045] Furthermore, combined Figure 3 , Figure 5 and Figure 7 As shown, the interlock device 20 includes a transmission member 11. When the shift lever 21 is engaged in the D-gear shift groove 23, one end of the transmission member 11 is away from the D-gear shift groove 23 and the other end is engaged in the opening 29, thereby linking the D-gear shift groove 23 and the first gear shift groove 22. In other words, the interlock device 20 achieves the linkage between the D-gear shift groove 23 and the first gear shift groove 22 through the transmission member 11. For example, when the shift lever 21 is engaged in the D-gear shift groove 23, one end of the transmission member 11 is abutted by the shift lever 21, causing one end of the transmission member 11 to move away from the D-gear shift groove 23, thereby causing the other end of the transmission member 11 to engage in the opening 29 of the linkage part 25, thus achieving the linkage between the D-gear shift groove 23 and the first gear shift groove 22.
[0046] Thus, by setting the transmission component 11, the linkage between the D gear shift slot 23 and the first gear shift slot 22 can be realized. When the shift lever 21 is pushed forward, the push lever drives the D gear shift slot 23 to move forward, which in turn drives the first gear shift slot 22 to move forward, so that the transmission 100 can output power when it is not engaged in a forward gear.
[0047] Furthermore, combined Figure 3 , Figure 5 and Figure 7 As shown, a second elastic element 28 is provided within the opening 29. The second elastic element 28 selectively applies an elastic force to the transmission component 11. That is, the second elastic element 28 can apply an elastic force to the transmission component 11. When the other end of the transmission component 11 is engaged within the opening 29, the second elastic element 28 is compressed, thereby allowing the second elastic element 28 to apply an elastic force to the transmission component 11. When the shift lever 21 leaves the D shift slot 23, the elastic force can reset the transmission component 11, thereby disengaging the linkage between the D shift slot 23 and the first shift slot 22.
[0048] That is, the second elastic element 28 can push the transmission element 11 away from the outlet 29 under normal conditions, thereby avoiding the linkage between the D gear shift slot 23 and the first gear shift slot 22 when the vehicle is running normally.
[0049] Furthermore, a baffle is also provided inside the opening 29. The baffle is located between the second elastic member 28 and the transmission member 11. By providing the baffle, direct contact between the transmission member 11 and the second elastic member 28 can be avoided, thereby preventing uneven force on the second elastic member 28.
[0050] Combination Figure 3 , Figure 5 and Figure 7 As shown, according to an optional embodiment of the present invention, the transmission component 11 includes a storage tube 12 and a ball chain 13. The ball chain 13 is located inside the storage tube 12 and can reciprocate within the storage tube 12. One end of the storage tube 12 is fixedly connected to the D gear shift groove 23, and the other end is opposite to the first gear shift groove 22. When the shift lever 21 is engaged in the D gear shift groove 23, one end of the ball chain 13 is away from the D gear shift groove 23, and the other end is engaged in the opening 29. That is, the ball chain 13 is considered a rigid body in the storage tube 12. When the shift lever 21 is engaged in the D gear shift groove 23, one end of the ball chain 13 is pushed by the shift lever 21, thereby causing the ball chain 13 to move as a whole within the storage tube 12, and thus causing the other end of the ball chain 13 to engage in the opening 29 of the linkage part 25. This enables linkage between the D gear shift groove 23 and the first gear shift groove 22.
[0051] Furthermore, bullet heads 14 are provided at both ends of the ball chain 13, so that when the ball head of the shift lever 21 engages with the D gear shift groove 23, it will push the bullet head 14 at one end of the ball chain 13, thereby causing the bullet head 14 at the other end of the ball chain 13 to engage with the opening 29.
[0052] The transmission component 11 includes a rotating shaft and a transmission rod. The transmission rod is rotatably fixed to the D-gear shift groove 23 via the rotating shaft. One end of the transmission rod corresponds to the D-gear shift groove 23, and the other end corresponds to the opening 29. When the shift lever 21 is engaged in the D-gear shift groove 23, one end of the transmission rod is away from the D-gear shift groove 23, and the other end is engaged in the opening 29. Thus, when the shift lever 21 is engaged in the D-gear shift groove 23, one end of the transmission rod is pushed by the shift lever 21, causing the transmission rod to rotate relative to the rotating shaft. Consequently, the other end of the transmission rod engages in the opening 29 of the linkage part 25, thereby realizing the linkage between the D-gear shift groove 23 and the first gear shift groove 22.
[0053] And, combined Figure 1 and Figure 2 As shown, a drive gear 41 is mounted on the input shaft 40. The drive gear 41 and the output shaft 30 are selectively connected for transmission. A multi-plate clutch 43 and a first synchronizer 42 are provided between the drive gear 41 and the input shaft 40. That is, a drive gear 41 is provided on the output shaft 30, wherein the drive gear 41 can be connected for transmission with the output shaft 30, thereby transmitting the power of the input shaft 40 to the output shaft 30.
[0054] Furthermore, a multi-plate clutch 43 and a first synchronizer 42 are provided between the drive gear 41 and the input shaft 40, so that power from the input shaft 40 can be transmitted to the drive gear 41 through the multi-plate clutch 43 or the first synchronizer 42. For example, when the vehicle is parked but the engine is started, both the first synchronizer 42 and the multi-plate clutch 43 are disengaged from the drive gear 41, thus preventing power from the input shaft 40 from being transmitted to the drive gear 41; or, for example, when the vehicle is driving normally, such as when the transmission 100 is in reverse or drive gear, the first synchronizer 42 engages the drive gear 41 and the input shaft 40, thus transmitting power from the input shaft 40 to the drive gear 41; or, for example, when the vehicle is crawling, the multi-plate clutch 43 engages the drive gear 41 and the input shaft 40, thus transmitting a portion of the power from the input shaft 40 to the drive gear 41.
[0055] Furthermore, combined Figure 1 and Figure 2 As shown, a driven gear 31 and a second synchronizer 32 are provided on the output shaft 30. The second synchronizer 32 selectively engages the driven gear 31 and the output shaft 30. For example, when the vehicle is parked but the engine is started, the second synchronizer 32 disengages from the driven gear 31, thus preventing power from being transmitted from the driven gear 31 to the input shaft 40. Or, for example, when the vehicle is in normal driving, such as when the transmission 100 is in reverse or drive, the second synchronizer 32 engages the driven gear 31 and the output shaft 30, thus allowing power from the driven gear 31 to be transmitted to the output shaft 30.
[0056] Reference Figures 2-8 As shown, the multi-plate clutch 43 has a limit ring 432 on one side and a clutch body 431 on the other side. A gear ring 44 is mounted on the input shaft 40 and is positioned opposite the limit ring 432. The gear ring 44 engages with the D-gear shift groove 23. When the D-gear shift groove 23 is pushed with different forces, the gear ring 44 compresses the limit ring 432, causing the clutch body 431 to output different torques. In other words, by varying the contact force between the gear ring 44 and the limit ring 432, the clutch body 431 can output different torques, resulting in different vehicle speeds when the shift lever 21 is located in the D-gear shift groove and is pushed.
[0057] Specifically, when the user pushes the shift lever 21, the greater the pushing force, the greater the force applied by the gear ring 44 to the limit ring 432, which in turn makes the torque output by the clutch body 431 greater, and thus makes the vehicle travel faster.
[0058] According to a second aspect of the present invention, a vehicle includes a transmission 100.
