进一步地，所述传动轮由多组同轴叶片轮组成，各组同轴叶片轮连接在同一根传动轴上，每组同轴叶片轮拥有独立的舱室，动力油通过动力油传递孔在所述独立的舱室内推动该组同轴叶片轮转动。Further, the transmission wheel is composed of a plurality of sets of coaxial blade wheels, each set of coaxial blade wheels are connected on the same transmission shaft, each set of coaxial blade wheels has an independent compartment, and the power oil passes through the power oil transmission hole.

When the gear control panel covers part of the power oil transmission hole, only part of the power oil transmission hole passes the action oil, and the blades on the transmission wheel contact the power oil. The number of the transmission wheel is reduced, and the driving wheel rotates under the action of the pressing.

下面结合附图说明及具体实施方式对本发明进一步说明。The invention will now be further described with reference to the drawings and specific embodiments.
如附图1所示，本发明的液压无级变速器包括：活塞1、档位控制板
2、传动轮3，液压腔4；其中，所述传动轮上有多片同轴叶片5；所述活塞在所述液压腔内运动；所述液压腔上有一个出口6和一个进口7，所述出口和进口上均设置有单向阀门8；所述出口通过动力油动力输出通道9与传动轮3相接，在动力油动力输出通道9的出口与传动轮3之间有若干个动力油传递孔10，所述动力油传递孔10与覆盖在其上的档位控制板2合作完成变速功能；所述进口7通过动力油循环回流通道11与传动轮3相接；发动机12可通过连杆13带动活塞1运动，抽取和挤压动力油做功，动力油被活塞1增压后，穿过所述动力油传递孔10推动传动轮3转动，动力油完成推动传动轮的过程后，通过所述动力油循环回流通道11和进口7被活塞1重新抽取和再次挤压做功。As shown in FIG. 1, the hydraulic continuously variable transmission of the present invention comprises: a piston 1, a gear position control board
2, the transmission wheel 3, the hydraulic chamber 4; wherein the transmission wheel has a plurality of coaxial blades 5; the piston moves in the hydraulic chamber; the hydraulic chamber has an outlet 6 and an inlet 7, Both the outlet and the inlet are provided with a one-way valve 8; the outlet is connected to the transmission wheel 3 through the power oil power output passage 9, and there are several powers between the outlet of the power oil power output passage 9 and the transmission wheel 3. The oil transfer hole 10, the power oil transmission hole 10 cooperates with the gear position control plate 2 covered thereon to complete the shifting function; the inlet 7 is connected to the transmission wheel 3 through the power oil circulation return passage 11; the engine 12 can pass The connecting rod 13 drives the piston 1 to move, extracts and squeezes the power oil to work, and after the power oil is pressurized by the piston 1, the driving oil wheel 3 is pushed through the power oil transmission hole 10 to rotate, and after the power oil completes the process of pushing the transmission wheel, The work is re-extracted and re-extrusion by the piston 1 through the power oil circulation return passage 11 and the inlet 7.
为保证动力油做功的连续性和平稳性，液压腔可以设计2个或者多个，同时，每个液压腔内对应有一个活塞。这样一个液压腔在抽取动力油时，其它的液压腔在进行挤压做功，使得动力油做功时保持稳定的压力状态。In order to ensure the continuity and stability of the power oil work, the hydraulic chamber can be designed with two or more, and at the same time, there is one piston in each hydraulic chamber. When such a hydraulic chamber extracts the power oil, the other hydraulic chambers perform the work of squeezing, so that the power oil maintains a stable pressure state when the work is done.
采用单向阀门可以控制动力油的流向只朝一个方向进行。如附图2(a)所示，动力油泵出时出口处单向阀门打开，而进口处的单向阀门闭合，此时动力油只能通过动力油动力输出通道流向动力油传递孔；如附图2(b)所示，动力油吸入时进口处单向阀门打开，而出口处单向阀门闭合，此时动力油只能通过动力油循环回流通道从传动轮流入液压腔。这样就实现了动力油在循环过程中整体参与，动力传递直接且效率接近100％。The one-way valve can be used to control the flow of the power oil in only one direction. As shown in Fig. 2(a), the one-way valve at the outlet of the power oil pumping is opened, and the one-way valve at the inlet is closed. At this time, the power oil can only flow through the power oil power output passage to the power oil transmission hole; As shown in Fig. 2(b), when the power oil is sucked, the one-way valve at the inlet opens, and the one-way valve at the outlet is closed. At this time, the power oil can only flow from the transmission wheel into the hydraulic chamber through the power oil circulation return passage. This achieves the overall participation of the power oil in the cycle, the power transmission is direct and the efficiency is close to 100%.
动力油传递孔及覆盖在其上的档位控制板合作完成变速功能，档位控制板可以移动位置改变覆盖住的动力油传递孔数量。其中，附图3(a)是抵挡高扭矩时档位控制板未覆盖动力油传递孔，此时，露出3排动力油传递孔；附图3(b)是中挡中扭矩时档位控制板覆盖部分动力油传递孔，此时，露出2排动力油传递孔；附图3(c)是高挡低扭矩时档位控制板覆盖部分动力油传递孔，此时，露出1排动力油传递孔。The power oil transmission hole and the gear position control plate covered thereon cooperate to complete the shifting function, and the gear position control plate can move the position to change the number of power oil transmission holes covered. 3(a) is the gear control board not covering the power oil transmission hole when the high torque is resisted, at this time, the 3 rows of power oil transmission holes are exposed; FIG. 3(b) is the gear position control in the middle gear. The plate covers part of the power oil transmission hole. At this time, two rows of power oil transmission holes are exposed; FIG. 3(c) is a high-speed low-torque gear position control plate covering a part of the power oil transmission hole, and at this time, a row of power oil is exposed. Pass the hole.
a)当档位控制板完全放开，所有动力油传递孔均可放行动力油通过，使传动轮上的最多叶片接触动力油，在其挤压作用下传动轮转动，此时动力油与传动轮叶片的接触面积最大，动力油移动速度最慢，但是产生的压力最大，扭矩最大。a) When the gear control panel is completely released, all the power oil transmission holes can pass the action oil, so that the most blades on the transmission wheel are in contact with the power oil, and the drive wheel rotates under the action of the squeeze. At this time, the power oil and the transmission The contact area of the wheel blades is the largest, and the moving oil moves at the slowest speed, but the pressure generated is the largest and the torque is the largest.
b)当档位控制板覆盖部分动力油传递孔时，只有部分动力油传递孔可以放行动力油通过，使传动轮上的叶片接触动力油的数量减少，在其挤压作用下传动轮转动，此时动力油与传动轮叶片的接触面积减少，压强增大，动力油移动速度加快，扭矩降低，但是可以提供传动轮的高转速。
b) When the gear control board covers part of the power oil transmission hole, only part of the power oil transmission hole can pass the action oil, so that the number of blades contacting the power oil on the transmission wheel is reduced, and the driving wheel rotates under the action of the squeeze.
