Definitions
- the present invention relates to a mechanical transmission, and more particularly to a flexibly activated continuously variable transmission.
- the automatic transmission is divided into a hydraulic automatic transmission (AT), an electronically controlled mechanical automatic transmission (AMT) and a continuously variable transmission (CVT).
- AT hydraulic automatic transmission
- AMT electronically controlled mechanical automatic transmission
- CVT continuously variable transmission
- torque converter the most widely used and most loaded component is a torque converter, but now
- the existing manual transmission mainly replaces the gear by adjusting different gear combinations; the existing electronically controlled mechanical automatic transmission (AMT) is installed on the basis of the conventional dry clutch and manual gear transmission.
- the electronic control system transforms the manual shifting mechanism into an automatic shifting mechanism, thereby realizing automatic shifting of the stepped mechanical automatic transmission.
- the disadvantage is that the flexible transmission cannot be provided, the stepless shifting cannot be realized, and the control structure is complicated.
- the existing hydraulic transmission includes a torque converter and a transmission that increases control based on the torque converter, such as a hydraulic automatic transmission (AT), and the torque converter is connected through the housing.
- the pump wheel and the pump wheel agitate the oil in the torque converter, and the turbine rotates through the guide wheel, and the turbine outputs the power.
- the disadvantage is that when the speed difference between the pump wheel and the turbine of the torque converter is close to synchronization, the transmission is lost. Capacity, synchronization cannot be achieved; in order to improve the above problems of the torque converter, when the control system is added, the system is complicated and the manufacturing cost is high.
- the existing continuously variable transmission transmits power by using a transmission belt with a transmission friction force and a variable working main and driven wheels, which can realize continuous change of the transmission ratio, thereby obtaining the power train and the engine working condition.
- the best match, the shortcoming is that it can not provide flexible zero start, can not provide a large torque, easy to slip when the force changes frequently.
- the liquid contained in the inner casing 2 forms an annular liquid surface in the inner casing 2 due to the centrifugal force.
- the liquid enters each of the bucket wheels into a concave bucket wheel 22 .
- the liquid entering the bucket wheel 22 forces the rotation speed of the bucket wheel 9 to gradually decrease until the rotation stops due to the centrifugal force.
- the output shaft 8 gradually increases in speed, and finally the input shaft 7, the inner casing 2, the planetary gear 11,
- the bucket wheel 9, the reverse wheel, the 12, the large ring gear 14 and the output shaft 8 are all rotated at the same speed to achieve a soft start of the load.
- the liquid level of the liquid attached to the inner surface of the inner casing 2 determines the magnitude of the centrifugal force, and the magnitude of the centrifugal force further determines whether the output shaft 8 can rotate synchronously with the input shaft 7.
- the current on the motor measured by the current transformer 604 reaches a set value, for example, greater than or equal to 120A (step 701) and Pt100 platinum thermal resistance 602 measured.
- the signal is transmitted to the single chip microcomputer 601, and the single chip microcomputer 601 further controls the brake wheel through the electromagnetic brake 15.
- step 702 the brake wheel 16 starts to mesh with the sun gear 13, thereby braking the sun gear 13, and the sun gear 13 further transmits the braking force to the reversing wheel 12, the planetary gear 11, and the large ring gear 14, Finally, the output shaft 8 is reached, and the output shaft speed is decreased to increase the torque; at the same time, the single chip microcomputer 601 transmits a signal to the electromagnetic valve 609, and the electromagnetic valve 609 is opened, and the liquid of the inner box is emptied by fixing the scoop tube 18 and the oil discharge line 17, This reduces power loss. After the electromagnetic brake 15 is braked, the complete set of gear mechanisms participating in the brake is actually a conventional planetary gear reducer structure.
- the disadvantage of the hydraulic synchronous double speed device is that the balance force between the bucket wheel and the oil is limited, and the torque can only be changed within the maximum balance force of the oil to the bucket wheel; the output shaft needs to be larger than the maximum of the oil and the bucket wheel When the balance force can provide the torque, the oil of the inner box body needs to be emptied.
- the gear mechanism involved in the braking is a commonly used planetary gear reducer structure, and does not have the flexible transmission function; the entire control system belongs to the electronic control system, and Control, braking and other devices are complex in structure.
- the invention is to solve the problem that the existing manual transmission (MT) can not provide flexible transmission, and the control is complicated; the hydraulic transmission loses transmission capacity when synchronized, and cannot be synchronized; the hydraulic automatic transmission control system is complicated and high in cost; the continuously variable transmission (CVT) Can not provide flexible zero start, can not provide large torque, easy to slip when the force changes frequently; the balance between the hydraulic synchronous double-speed bucket wheel and the oil is limited, only the largest in the oil to the bucket wheel The torque in the balance force; when the output shaft needs to be greater than the maximum balance force of the oil and the bucket wheel, the oil of the inner tank needs to be emptied, and the gear mechanism involved in the brake is a commonly used planetary gear reducer.
- the structure does not have the flexible transmission function; the whole control system belongs to the electronic control system, and the technical problems of the structure of the control and braking devices are complicated, and the torque is provided not only in the maximum balance force of the oil to the bucket wheel, but also the output shaft
- the torque required to be greater than the maximum balance force of the oil and the bucket wheel is required, the oil of the inner tank is not required to be emptied, and the gear mechanism is not required to participate in the braking, thereby achieving continuous shifting and Range torque converter, comprising a flexible drive function, not need to add a control system, a continuously variable transmission with a simple structure.

自动变速器又分为液力自动变速器(AT)、电控机械式自动变速器(AMT)和无级变速器(CVT),其中应用最为广泛、装车率最多的部件是液力变矩器,但现有的变速器普遍存在以下问题:
(1)现有的手动变速器(MT)主要通过调节不同齿轮组合来更换挡位;现有的电控机械式自动变速器(AMT)在传统干式离合器和手动齿轮变速器的基础上,加装电子控制系统,将手动换档机构改造成自动换档机构,从而实现自动换档的有级式机械自动变速器,其缺点是不能提供柔性传动、无法实现无级变速、控制结构复杂。
(2)现有的液力变速器包括液力变矩器以及在液力变矩器基础上增加控制的变速器,如液力自动变速器(AT),液力变矩器是动力通过壳体相连的泵轮,泵轮搅动变矩器中的油液,通过导轮带动涡轮转动,涡轮将动力输出,其缺点是当液力变矩器的泵轮和涡轮的转速差接近同步时,会丧失传动能力,无法实现同步;为了改善液力变矩器存在的以上问题,增加控制系统时,又带来系统复杂,制造成本高的问题。
(3)现有的无级变速器(CVT)采用传动摩擦力和工作直径可变的主、从动轮相配合的传动带来传递动力,可以实现传动比的连续改变, 从而得到传动系与发动机工况的最佳匹配,其缺点是不能提供柔性零启动,不能提供较大的扭力,受力变化频繁时,易打滑。
(4)现有国内专利授权号为CN 102606709B的专利液力同步双速器,该液力同步双速器工作时,驱动装置带动输入轴7驱动内箱体2转动,同时将存放于外箱体1内的工作液体利用工作泵输送到内箱体2中,在内箱体2刚刚开始转动时,由于输出轴8上载有负荷,使与输出轴8固定连接的大齿圈14不转动,行星轮11、换向轮12、斗轮轴10和斗轮9跟随内箱体支架19一起绕输出轴8公转;同时,斗轮9高速绕斗轮轴10自转。随着内箱体2的继续转动,容纳在内箱体2内的液体由于离心力的作用在内箱体2内形成圆环状液面。当液面达到预定高度时,液体进入各个斗轮成凹形的斗轮叶片22内。进入斗轮叶片22内的液体由于离心力的作用迫使斗轮9的自转速度逐渐下降直至自转停止,此过程中,输出轴8转速逐渐上升,最终输入轴7、内箱体2、行星轮11、斗轮9、换向轮、12、大齿圈14和输出轴8都以相同的速度转动,实现了负荷的软启动。以上可以看出,贴在内箱体2的内表面上的液体的液位决定了离心力的大小,而离心力的大小进一步决定了输出轴8能否与输入轴7同步旋转。输出轴8越趋于与输入轴7同步转动,输出轴8与输入轴7之间的滑差越小。如图7所示,液力同步双速器在工作过程中,电流互感器604测量的电机上的电流达到设定值,例如大于或等于120A时(步骤701)以及Pt100铂热电阻602测量的外箱体1或内箱体2内液体的温度达到设定的值,例如大于或等于70℃时(步骤703),会将信号传递给单片机601,单片机601进而通过电磁制动器15控制制动轮16(步骤702),制动轮16与太阳轮13开始啮合,从而对太阳轮13进行制动,太阳轮13进一步将制动力依次传递到换向轮12、行星轮11、大齿圈14,最后到达输出轴8,降低输出轴转速以增加扭矩;同时,单片机601将信号传递给电磁阀609,电磁阀609开启,通过固定勺管18和出油管路17将内箱体的液体排空,这样就减小了功率损失。在电磁制动器15制动后,整套参与制动的齿轮机构实际上就是一个常 用的行星齿轮减速器结构。
该液力同步双速器的缺点是,斗轮与油液之间的平衡力有限,只能在油液对斗轮的最大平衡力内变矩;输出轴需要大于油液与斗轮的最大平衡力所能提供扭矩时,需将内箱体的油液排空,参与制动的齿轮机构是一个常用的行星齿轮减速器结构,不具备柔性传动功能;整个控制系统属于电子控制系统,且控制、制动等装置结构复杂。
发明内容
本发明就是要解决现有的手动变速器(MT)不能提供柔性传动,控制复杂;液力变速器同步时丧失传动能力,不能同步;液力自动变速器控制系统复杂,成本高;无级变速器(CVT)不能提供柔性零启动,不能提供较大的扭力,受力变化频繁时,易打滑;液力同步双速器斗轮与油液之间的平衡力有限,只能在油液对斗轮的最大平衡力内变矩;输出轴需要大于油液与斗轮的最大平衡力所能提供扭矩时,需将内箱体的油液排空,参与制动的齿轮机构是一个常用的行星齿轮减速器结构,不具备柔性传动功能;整个控制系统属于电子控制系统,且控制、制动等装置结构复杂的技术问题,提供一种不仅能在油液对斗轮的最大平衡力内变矩,输出轴需要大于油液与斗轮的最大平衡力所能提供扭矩时,不需将内箱体的油液排空,不需要齿轮机构参与制动,实现连续变速和宽范围变矩,具备柔性传动功能,不需要再增加控制系统,结构简单的无级变速器。
