Description

Technical Field

[0001] This utility model relates to the field of continuously variable transmission (CVT) technology, and more specifically, to a multi-output CVT mechanism. Background Technology

[0002] CVT (Continuously Variable Transmission) technology uses a drive belt and variable-diameter primary and driven pulleys to transmit power, enabling continuous changes in the transmission ratio and thus achieving optimal matching between the transmission system and engine operating conditions.

[0003] In common continuously variable transmission (CVT) mechanisms, the transmission mechanism usually has only one input and one output, which to some extent restricts the application scenarios of this technology, especially when the deployment space is extremely limited. Utility Model Content

The input end of any of the CVT mechanisms is connected to the main power source, and the main power source can simultaneously drive the input ends of multiple sets of CVT mechanisms.

[0006] Furthermore, in this utility model, any of the aforementioned continuously variable transmission mechanisms includes an input conical shaft and an output conical shaft arranged at intervals, as well as a transmission belt and a drive mechanism. The central axis of the input conical shaft and the central axis of the output conical shaft are parallel to each other, and the large-diameter end of the input conical shaft and the small-diameter end of the output conical shaft are located on the same side. One end of the input conical shaft is connected to the aforementioned total power source. The input conical shaft and the output conical shaft are connected by the aforementioned transmission belt. The aforementioned drive mechanism is used to drive the aforementioned transmission belt to reciprocate in the direction of the central axis of the input conical shaft.

[0007] Furthermore, in this utility model, the total power source includes a driving gear and a driven gear disposed at one end of the input conical shaft, wherein the driven gear meshes with the driving gear.

[0008] Furthermore, in this utility model, the aforementioned driving mechanism is a lead screw and nut mechanism, wherein the moving direction of the nut of the lead screw and nut mechanism is parallel to the central axis of the aforementioned input tapered shaft; two locking rods are spaced apart on the nut, and the corresponding suspended section of the aforementioned transmission belt is locked between the two locking rods.

[0009] Furthermore, in this utility model, both the driven gear and the driving gear are spur gears.

[0010] Furthermore, in this invention, both the driven gear and the driving gear are bevel gears.

[0011] The beneficial effects of this utility model are: This utility model provides a multi-output continuously variable transmission (CVT) mechanism. By setting up a total power source and multiple CVT mechanisms, each CVT mechanism is connected to the total power source for transmission. This allows one input to correspond to multiple outputs, thereby expanding the application scenarios of the CVT mechanism. Attached Figure Description

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example 1 Please see Figures 1-6 This embodiment provides a technical solution: A multi-output continuously variable transmission (CVT) mechanism includes a total power source 101 and four sets of CVT mechanisms 201. The input end of any CVT mechanism 201 is connected to the total power source 101, and the total power source 101 can simultaneously drive the input ends of all four CVT mechanisms 201 to rotate. (Refer to...) Figures 4-6 In other embodiments of this example, the number of continuously variable transmission mechanisms 201 may be two, three, five, six or more.

[0016] Specifically, refer to Figure 3 In this embodiment, any continuously variable transmission (CVT) mechanism 201 includes an input conical shaft 2011 and an output conical shaft 2012 arranged at intervals, a transmission belt 2013, and a drive mechanism 2014. The central axis of the input conical shaft 2011 and the central axis of the output conical shaft 2012 are parallel to each other, and the large-diameter end of the input conical shaft 2011 and the small-diameter end of the output conical shaft 2012 are located on the same side. One end of the input conical shaft 2011 is connected to the main power source 101, and one end of the output conical shaft 2012 is connected to the corresponding mechanism. The input conical shaft 2011 and the output conical shaft 2012 are connected by the transmission belt 2013. The drive mechanism 2014 is used to drive the transmission belt 2013 to reciprocate in the direction of the central axis of the input conical shaft 2011.

[0017] Specifically, refer to Figure 1 In this embodiment, the total power source 101 includes a driving gear 1011 and a driven gear 1012 installed at one end of the input conical shaft 2011. The driven gear 1012 meshes with the driving gear 1011.

[0018] Preferably, in this embodiment, the drive mechanism 2014 is a lead screw and nut mechanism, and the moving direction of the nut of the lead screw and nut mechanism is parallel to the central axis of the input tapered shaft 2011; two clamping rods 301 are installed at intervals on the nut, and the corresponding suspended section of the transmission belt 2013 is clamped between the two clamping rods 301.

[0019] Preferably, in this embodiment, both the driven gear 1012 and the driving gear 1011 are spur gears. The central axis of both the driven gear 1012 and the driving gear 1011 is parallel to the central axis of any input conical shaft 2011 / output conical shaft 2012.

[0020] Working principle: Reference Figure 1 or Figure 2Each of the four input conical shafts 2011 has a driven gear 1012 at one end that meshes with a driving gear 1011. Thus, when the driving gear 1011 rotates, the four driven gears 1012 rotate synchronously, driving each of the four input conical shafts 2011 to rotate synchronously. Simultaneously, the four drive mechanisms 2014 can operate independently according to the output requirements of each output conical shaft 2012; that is, the movement speed of each nut can be the same or different. This structure enables one input to correspond to multiple outputs, expanding the application scenarios of the continuously variable transmission mechanism 201. This mechanism is suitable for applications such as multi-rotor drones and multi-joint transmission and control systems.

[0021] Example 2 Please see Figure 7 The difference between this embodiment and Embodiment 1 is that in this embodiment, both the driven gear 1012 and the driving gear 1011 are bevel gears. In this case, the central axis of the driving gear 1011 is perpendicular to the central axis of any input conical shaft 2011 / output conical shaft 2012, and the central axis of any driven gear 1012 is parallel to the central axis of the corresponding input conical shaft 2011 / output conical shaft 2012. Several continuously variable transmission (CVT) mechanisms 201 are arranged in a ring about the central axis of the driving gear 1011. This structure also expands the application scenarios of the CVT mechanism 201.
