Description
本發明係有關於一種可氣動調整的CVT-傳動裝置(可無級調整的傳動裝置)，其特別是用於小型車輛，如二輪車、三輪車、Quad車或雪地機動車，以及一種內燃機及一種車輛。 The present invention relates to a pneumatically adjustable CVT-transmission (infinitely adjustable transmission), in particular for small vehicles, such as two-wheelers, tricycles, quad or snowmobiles, and an internal combustion engine and a vehicle.
由先前技術已知CVT-傳動裝置的不同設計方案。與具有固定擋位的傳動裝置相比，採用可持續變化的傳動裝置後，可在車輛中達到合適的傳動比。此種CVT-傳動裝置的特別應用領域為小型車輛，如二輪車、三輪車(所謂的突突車)、雪地機動車、Quad車(四輪全地形車)或滑板車。在採用此類CVT-傳動裝置時，通常將離心力調節器用於調整傳動帶在錐形墊片對上的位置。在此情況下，離心力調節器的離心力重體根據轉速移動其徑向位置，從而改變兩個錐形墊片間的軸向距離，進而改變傳動裝置的傳動。此類裝置的缺點在於，無法主動對CVT-傳動裝置的傳動裝置傳動進行可控制或可調節性干預。在此情況下，有利者係一種用於對CVT-傳動裝置的傳動裝置傳動進行可控制或可調節性干預的簡單方案，其特別是可用於小型車輛。 Different designs of CVT-transmissions are known from the prior art. With a continuously variable transmission, a suitable gear ratio can be achieved in the vehicle compared to a transmission with a fixed gear. A particular field of application for such CVT-transmissions is small vehicles such as two-wheelers, tricycles (so-called spurs), snowmobiles, quads (four-wheeled all-terrain vehicles) or scooters. In the case of such a CVT-transmission, a centrifugal force regulator is typically used to adjust the position of the belt on the pair of tapered washers. In this case, the centrifugal force of the centrifugal force adjuster moves its radial position according to the rotational speed, thereby changing the axial distance between the two tapered washers, thereby changing the transmission of the transmission. A disadvantage of such a device is that it is not possible to actively control or adjust the transmission of the CVT-transmission drive. In this case, it is advantageous to use a simple solution for controllable or adjustable intervention of the transmission of the CVT-transmission, which can be used in particular in small vehicles.
而本發明之具有申請專利範圍第1項之特徵的CVT-傳動裝 置的優點在於，可有效地改良車輛的排放特性及燃料消耗，因為能夠對CVT-傳動裝置的傳動比進行可控制或可調節性干預。因此，特別是在自靜止狀態加速方面及在行駛中的車輛之加速方面的行駛動力學上，亦能顯著改良行駛性能。為此，根據本發明，設有用於調整軸向可動的錐形墊片之位置的調整裝置。該調整裝置為氣動調整裝置，其藉由氣動力調整該軸向可動的錐形墊片。如此便能在最佳工作點上操作該CVT-傳動裝置。在此情況下，該調整裝置包括氣動壓力箱，該氣動壓力箱與該軸向可動的錐形墊片連接，以便藉由氣動力調整該軸向可動的錐形墊片。如此便能實現簡單且緊湊的結構。 The CVT-drive device of the present invention having the features of claim 1 The advantage of this is that the emission characteristics and fuel consumption of the vehicle can be effectively improved because of the controllable or adjustable intervention of the transmission ratio of the CVT-transmission. Therefore, the driving performance can be significantly improved particularly in terms of the driving dynamics from the standstill acceleration and the acceleration of the running vehicle. To this end, according to the invention, an adjustment device for adjusting the position of the axially movable tapered gasket is provided. The adjustment device is a pneumatic adjustment device that adjusts the axially movable tapered gasket by aerodynamic forces. This allows the CVT-transmission to be operated at the optimum operating point. In this case, the adjustment device includes a pneumatic pressure tank that is coupled to the axially movable tapered gasket to adjust the axially movable tapered gasket by aerodynamic forces. This makes it possible to achieve a simple and compact structure.
該等附屬項顯示本發明之較佳改良方案。 These sub-items show a preferred refinement of the invention.
該CVT-傳動裝置較佳地包括負壓源，該負壓源與該壓力箱連接。該負壓源提供調整該軸向可動的錐形墊片所需之氣動力。在此情況下，該負壓源尤佳為內燃機的抽吸管。 The CVT-transducer preferably includes a source of negative pressure that is coupled to the pressure tank. The source of negative pressure provides the aerodynamic force required to adjust the axially movable tapered gasket. In this case, the negative pressure source is particularly preferably a suction pipe of an internal combustion engine.
該壓力箱進一步較佳地具有以下結構：在該壓力箱中佈置有可動活塞。在此情況下，該可動活塞與該軸向可動的錐形墊片較佳為機械連接。如此便能透過對該活塞施壓而使得該活塞運動，進而實現該軸向可動的錐形墊片之運動。其中，該活塞可被施加過壓或負壓。 The pressure tank further preferably has a structure in which a movable piston is disposed in the pressure tank. In this case, the movable piston is preferably mechanically coupled to the axially movable tapered gasket. In this way, the piston can be moved by applying pressure to the piston, thereby realizing the movement of the axially movable tapered gasket. Wherein, the piston can be applied with an overpressure or a negative pressure.
該壓力箱進一步較佳地與軸承單元連接，其中該軸向可動的錐形墊片支承在該軸承單元上。如此便實現該CVT-傳動裝置之特別緊湊的結構。 The pressure tank is further preferably connected to a bearing unit, wherein the axially movable tapered washer is supported on the bearing unit. This achieves a particularly compact construction of the CVT-actuator.
該CVT-傳動裝置較佳地亦包括離心力重體，該等離心力重體佈置在該軸向可動的錐形墊片上。在此情況下，該等離心力重體便已大 約根據該軸向可動的錐形墊片之轉速提供相應地與該轉速匹配的傳動比，其中隨後可藉由本發明之調整裝置對該傳動進行精調。如此便能特別是實現用於改變該傳動之較短的轉換時間。藉此產生特別簡單的結構。 The CVT-transducer preferably also includes a centrifugal force weight disposed on the axially movable tapered washer. In this case, the centrifugal force is already heavy. A gear ratio corresponding to the rotational speed is provided approximately according to the rotational speed of the axially movable conical shim, wherein the transmission can then be fine-tuned by the adjusting device of the present invention. In this way, in particular, a shorter switching time for changing the transmission can be achieved. This results in a particularly simple structure.
根據本發明之另一較佳設計方案，該活塞在該壓力箱中僅單側可被施加過壓或負壓。 According to a further refinement of the invention, the piston can be applied with an overpressure or a negative pressure on only one side of the pressure tank.
本發明亦有關於一種內燃機，包括本發明之CVT-傳動裝置。該內燃機較佳地包括至少一氣缸及一通向該氣缸的抽吸管，其中該抽吸管與該CVT-傳動裝置的氣動調整裝置連接，以便提供用於調整該CVT-傳動裝置的氣動力。其中，該抽吸管較佳地與該氣動儲存器連接。如此便能透過使用該抽吸管而將負壓用於氣動調整該CVT-傳動裝置。此點係特別有利，原因在於，在具有抽吸管的內燃機中本就存在負壓，該負壓可補充性地用於調整CVT-傳動裝置的傳動裝置傳動。 The invention also relates to an internal combustion engine comprising a CVT-transmission device of the invention. The internal combustion engine preferably includes at least one cylinder and a suction tube leading to the cylinder, wherein the suction tube is coupled to the pneumatic adjustment of the CVT-transmission to provide an aerodynamic force for adjusting the CVT-transmission. Wherein the suction tube is preferably connected to the pneumatic reservoir. Thus, the negative pressure can be used to pneumatically adjust the CVT-transmission device by using the suction pipe. This is particularly advantageous because in the internal combustion engine with the suction pipe there is inherently a negative pressure which can be used in a complementary manner for adjusting the transmission of the CVT transmission.
該調整裝置進一步較佳地構建為改裝工具。 The adjustment device is further preferably constructed as a retrofit tool.
本發明亦有關於一種車輛，包括本發明之CVT-傳動裝置及/或本發明之內燃機。 The invention also relates to a vehicle comprising the CVT-transmission device of the invention and/or the internal combustion engine of the invention.
該車輛較佳地具有車架，特別是車管或車管組，該車架構建為氣動儲存器。為此，設有空心框，在該空心框中，可將過壓或負壓作為氣動儲存器用於提供用於調整該CVT-傳動裝置的氣動力。在使用通常具有此種空心框的二輪車或三輪車時，此點係特別有利。如此便毋需其他用於該氣動儲存器的部件，而是僅需氣動密封地封閉空心管或類似部件的部分區段，以便用作氣動儲存器。 The vehicle preferably has a frame, in particular a vehicle tube or a vehicle tube set, which is constructed as a pneumatic reservoir. For this purpose, a hollow frame is provided, in which an overpressure or a negative pressure can be used as a pneumatic reservoir for providing an aerodynamic force for adjusting the CVT-transmission. This is particularly advantageous when using a two-wheeled or tricycle that typically has such a hollow frame. In this way, other components for the pneumatic reservoir are required, but only a partial section of the hollow tube or the like is closed in a pneumatically sealed manner for use as a pneumatic reservoir.
本發明之車輛較佳為小型車輛，特別是二輪車或三輪車或 Quad車或雪地機動車或滑板車或諸如此類。 The vehicle of the present invention is preferably a small vehicle, particularly a two-wheeled vehicle or a tricycle or Quad or snowmobile or scooter or the like.

A schematic view of the adjustment valve of the apparatus, and FIG. 4 is a schematic illustration of an alternative adjustment valve for the CVT-transmission of the present invention.
下面參照圖1至3對根據本發明之較佳實施例的CVT-傳動裝置1，即可持續調整的無級傳動裝置，進行詳細說明。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A CVT-transmission device 1 according to a preferred embodiment of the present invention, that is, a continuously adjustable continuously variable transmission, will now be described in detail with reference to Figs.
如圖1所示，CVT-傳動裝置1包括具有位置固定的錐形墊片20及軸向可動的錐形墊片21之錐形墊片對2。第二錐形墊片對用作從動元件13。該二錐形墊片對以習知的方式透過包容構件12，特別是傳動帶，相連。 As shown in FIG. 1, the CVT-transmission device 1 includes a tapered gasket pair 2 having a fixed tapered washer 20 and an axially movable tapered washer 21. The second tapered spacer pair serves as the driven element 13. The two conical spacers are connected in a conventional manner through the containment member 12, in particular the drive belt.
第一錐形墊片對2佈置在內燃機10的曲軸11上。在此情況下，曲軸11與位置固定的錐形墊片20固定連接。 The first tapered spacer pair 2 is disposed on the crankshaft 11 of the internal combustion engine 10. In this case, the crankshaft 11 is fixedly coupled to the fixed tapered washer 20.
CVT-傳動裝置1亦包括離心力元件3，該等離心力元件佈置在軸向可動的錐形墊片21上。在該實施例中，離心力元件3為球體。作為替代方案，亦可使用實心圓柱體或空心圓柱體或類似元件。 The CVT-transmission 1 also includes a centrifugal force element 3 which is arranged on an axially movable conical spacer 21. In this embodiment, the centrifugal force element 3 is a sphere. As an alternative, a solid cylinder or a hollow cylinder or the like can also be used.
此外，CVT-傳動裝置1包括支撐元件4，其佈置在軸向可動 的錐形墊片21上。在此情況下，離心力元件3佈置在支撐元件4與軸向可動的錐形墊片21之間。在軸向可動的錐形墊片21上，在對準支撐元件4的一面上設有相應的接觸面22，該等離心力元件沿該接觸面運動。 Furthermore, the CVT-transmission 1 comprises a support element 4 which is arranged to be axially movable The tapered gasket 21 is on. In this case, the centrifugal force element 3 is arranged between the support element 4 and the axially movable conical spacer 21. On the axially movable conical spacer 21, a corresponding contact surface 22 is provided on one side of the alignment support element 4, along which the centrifugal force elements move.
為調整軸向可動的錐形墊片21之軸向位置，設有調整裝置5。調整裝置5設為氣動調整裝置且包括氣動壓力箱50，該氣動壓力箱與軸向可動的錐形墊片21連接。壓力箱50包括佈置在該壓力箱中的活塞51及桿件52，該桿件自壓力箱50引出。桿件52與軸承單元56連接，軸向可動的錐形墊片21支承在該軸承單元上。軸承單元56包括內套筒53、外套筒54及佈置在該內套筒與該外套筒間的軸承55。 In order to adjust the axial position of the axially movable tapered washer 21, an adjustment device 5 is provided. The adjustment device 5 is provided as a pneumatic adjustment device and comprises a pneumatic pressure tank 50 which is connected to an axially movable conical gasket 21. The pressure tank 50 includes a piston 51 and a rod 52 disposed in the pressure tank, the rod being drawn from the pressure tank 50. The rod member 52 is coupled to the bearing unit 56, and the axially movable tapered gasket 21 is supported on the bearing unit. The bearing unit 56 includes an inner sleeve 53, an outer sleeve 54, and a bearing 55 disposed between the inner sleeve and the outer sleeve.
如圖2所示，內套筒53穿過位置固定的錐形墊片20。此外，在支撐元件4上設有柱形套筒區域41，內套筒53可滑動地佈置在該套筒區域上。內套筒53與軸向可動的錐形墊片21固定連接。 As shown in Figure 2, the inner sleeve 53 passes through a conical gasket 20 that is fixed in position. Furthermore, a cylindrical sleeve region 41 is provided on the support element 4, on which the inner sleeve 53 is slidably arranged. The inner sleeve 53 is fixedly coupled to the axially movable tapered washer 21.
在此情況下，軸承55中斷將曲軸11的旋轉傳遞至調整裝置5。透過套筒區域41及內套筒53將曲軸11的旋轉傳遞至軸向可動的錐形墊片21。 In this case, the bearing 55 interrupts the transmission of the rotation of the crankshaft 11 to the adjustment device 5. The rotation of the crankshaft 11 is transmitted through the sleeve region 41 and the inner sleeve 53 to the axially movable tapered washer 21.
該壓力箱中的活塞51將該壓力箱的內部區域分成兩個區域，即負壓區15及常壓區25。 The piston 51 in the pressure tank divides the inner region of the pressure tank into two regions, a negative pressure region 15 and a normal pressure region 25.
如圖1及2所示，壓力箱50與內燃機10的抽吸管9連接。其中，抽吸管9提供用於調整裝置5的負壓源。 As shown in FIGS. 1 and 2, the pressure tank 50 is connected to the suction pipe 9 of the internal combustion engine 10. Therein, the suction tube 9 provides a source of negative pressure for the adjustment device 5.
抽吸管9透過第一管路16與負壓儲存器7連接。在此情況下，負壓儲存器7透過第二管路17與壓力箱50連接。其中，在第一管路16中設有自動閉合的止回閥18。在第二管路17中設有可控制的調整閥8。 在此情況下，藉由控制單元6控制調整閥8。 The suction pipe 9 is connected to the negative pressure accumulator 7 through the first line 16. In this case, the negative pressure accumulator 7 is connected to the pressure tank 50 through the second line 17. Therein, an automatic closed check valve 18 is provided in the first line 16. A controllable regulating valve 8 is provided in the second line 17. In this case, the regulating valve 8 is controlled by the control unit 6.
曲軸11支承在殼體14上。 The crankshaft 11 is supported on the housing 14.
圖3為調整閥8的細節圖。在該實施例中，調整閥8為3/3換向閥，其中一方面可將壓力箱50的負壓區15與負壓儲存器7連接，另一方面可將該負壓區與環境19連接。該3/3換向閥的第三位置為圖3所示之完全閉合的位置。 FIG. 3 is a detailed view of the adjustment valve 8. In this embodiment, the adjustment valve 8 is a 3/3 reversing valve, wherein on the one hand the negative pressure zone 15 of the pressure tank 50 can be connected to the negative pressure reservoir 7, and on the other hand the negative pressure zone can be connected to the environment 19 connection. The third position of the 3/3 directional valve is the fully closed position shown in FIG.
活塞51僅單側可被施加負壓。 The piston 51 can be applied with a negative pressure on only one side.
因此，具體視該3/3換向閥的位置可沿箭頭A(參加圖2)所示方向或者沿相反的方向調整活塞51。作為替代方案，例如亦可將佈置在壓力箱50之負壓區15中的彈簧元件用於進行復位。 Therefore, depending on the position of the 3/3 directional control valve, the piston 51 can be adjusted in the direction indicated by the arrow A (see Fig. 2) or in the opposite direction. As an alternative, for example, a spring element arranged in the vacuum region 15 of the pressure tank 50 can also be used for resetting.
因此，根據本發明，將在內燃機10中處於抽吸管9中的負壓作為氣動能源用於調整CVT-傳動裝置1的傳動。在此情況下，抽吸管9中的壓力水平取決於節流閥閥舌位置及該內燃機的轉速。因此，在該內燃機的工作中，可持續確保負壓儲存器7的負壓供應，進而簡便且安全地藉由氣動力調整軸向可動的錐形墊片21。 Therefore, according to the present invention, the negative pressure in the internal combustion engine 10 in the suction pipe 9 is used as a pneumatic energy source for adjusting the transmission of the CVT-transmission device 1. In this case, the pressure level in the suction pipe 9 depends on the position of the throttle valve tongue and the rotational speed of the internal combustion engine. Therefore, in the operation of the internal combustion engine, the supply of the negative pressure of the negative pressure accumulator 7 can be continuously ensured, and the axially movable tapered washer 21 can be easily and safely adjusted by aerodynamic force.
壓力箱50較佳地佈置在曲軸11的軸向末端上。如此便能實現特別緊湊且機械簡單的結構。 The pressure tank 50 is preferably disposed on the axial end of the crankshaft 11. This makes it possible to achieve a particularly compact and mechanically simple structure.
此外，透過藉由負壓調整該傳動裝置傳動亦可將離心力元件3的大小和重量減小約20%。與先前技術相比，如此便能特別是達到該CVT-傳動裝置的重量減小。此外，透過藉由壓力箱50調整該CVT-傳動裝置亦可實現已存在的CVT-傳動裝置之可改裝性。 Furthermore, the size and weight of the centrifugal force element 3 can also be reduced by about 20% by adjusting the transmission by negative pressure. This makes it possible in particular to achieve a reduction in the weight of the CVT-transmission compared to the prior art. In addition, the configurability of the existing CVT-transmission can also be achieved by adjusting the CVT-transmission by the pressure box 50.
負壓儲存器7尤佳佈置在車輛的空心框中，為此，在車輛中 毋需其他用於該負壓儲存器的空間。 The negative pressure reservoir 7 is preferably arranged in the hollow frame of the vehicle, for this purpose, in the vehicle There is no need for other space for this negative pressure reservoir.
