背景技术Background technique
车用变速器由有级变速向无级变速是未来的发展趋势。It is the future development trend for vehicle transmission to change from stepped to continuously variable.
目前广泛应用于汽车上的无级变速器以金属带式无级变速器为主。金属带式无级变速器在汽车中应用取得了很好的效果，但是它有三个方面的不足：一是变速器的成本较高，金属带由多个钢片叠加而成，零件数目多，对制造、装配和材料的要求都很高，导致变速器的成本较高；二是传递的力矩较小，金属带式无级变速器通过带轮与金属块间的摩擦力矩传递动力，传递力矩必然受到金属带与带轮工作表面之间的压力和表面摩擦系数的制约，难于实现大扭矩输出；三是带和带轮之间容易产生磨损，影响变速器的使用寿命。金属带式无级变速器目前仅用于中小排量的轿车上。Currently, the CVTs widely used in automobiles are mainly metal belt CVTs. The metal belt type continuously variable transmission has achieved good results in the application of automobiles, but it has three shortcomings: first, the cost of the transmission is relatively high, the metal belt is made of multiple steel sheets, and the number of parts is large. , Assembly and material requirements are very high, resulting in higher cost of the transmission; second, the transmitted torque is small, the metal belt continuously variable transmission transmits power through the friction torque between the pulley and the metal block, and the transmission torque is bound to be affected by the metal belt. The pressure between the working surface of the pulley and the restriction of the surface friction coefficient make it difficult to achieve high torque output; the third is that wear is prone to occur between the belt and the pulley, which affects the service life of the transmission. Metal belt continuously variable transmissions are currently only used in small and medium displacement cars.
牵引式无级变速器是一种具有广泛应用前景的变速器，它由主动锥盘、传力滚轮、从动锥盘组成，动力滚轮与主动锥盘和从动锥盘没有直接接触，主动锥盘与动力滚轮之间有一层牵引油膜，动力滚轮和从动锥盘之间也有一层牵引油膜，动力依靠油膜的剪切力传递。由于各传力部件没有直接接触，牵引式无级变速器没有磨损。与带式无级变速器相比，牵引式无级变速器具有零件少、成本低、无磨损、能传递较大力矩的优点。2003年3月7日在底特津结束的SAE年会上，将牵引式无级变速器称为IVT，并将它作为未来汽车变速器发展的重点方向。The traction continuously variable transmission is a kind of transmission with wide application prospects. It is composed of a driving cone, a power transmission roller and a driven cone. The power roller has no direct contact with the driving cone and the driven cone. There is a layer of traction oil film between the power rollers, and there is also a layer of traction oil film between the power roller and the driven cone, and the power is transmitted by the shear force of the oil film. Since the power transmission parts are not in direct contact, the traction continuously variable transmission is free from wear. Compared with the belt type continuously variable transmission, the traction type continuously variable transmission has the advantages of less parts, low cost, no wear and can transmit larger torque. On March 7, 2003, at the SAE annual meeting that ended in Detroit, the traction continuously variable transmission was called IVT, and it was regarded as the key direction of future automotive transmission development.
牵引式无级变速器的牵引油膜形状为一个小椭圆，在传递动力时，如果主动件和从动件与牵引油膜椭圆接触区域内各点的速度不一致，就会导致油膜的滑动、错位或撕裂，这种现象称为自旋。重庆大学秦大同教授等人对全环面和半环面牵引式无级变速器进行了深入系统地研究，研究结果表明：自旋是引起牵引式无级变速器功率损失的最大原因，现有全环面和半环面牵引式无级变速器无法消除自旋现象。The shape of the traction oil film of the traction CVT is a small ellipse. When transmitting power, if the speeds of the points in the contact area of the driving part and the driven part and the traction oil film ellipse are inconsistent, the oil film will slide, dislocate or tear , this phenomenon is called spin. Professor Qin Datong of Chongqing University and others have carried out in-depth and systematic research on the full toroidal and half toroidal traction continuously variable transmissions. Surface and half toroidal traction CVTs cannot eliminate spin.
为消除牵引式无级变速器的自旋损失，四川大学李青涛等人以求解微分方程的方法，得到一种无自旋变速单元（专利申请公布号CN104776180A），这种无自旋变速单元的主动锥盘和从动锥盘的母线均为对数曲线，在调速的过程中，主动锥盘和从动锥盘都要产生移动，动力滚轮既要产生转动又要产生移动。这种牵引式无级变速器虽然消除了自旋，但存在两个方面的困难：一是主动锥盘和从动锥盘的母线复杂的对数曲线，制造比较困难；二是调速控制比较麻烦，调速时动力滚轮既有转动又有移动，主动锥盘和从动锥盘也会沿其轴线移动，调速控制难度较大。In order to eliminate the spin loss of the traction continuously variable transmission, Li Qingtao of Sichuan University and others obtained a spinless speed change unit (patent application publication number CN104776180A) by solving differential equations. The active cone of this spinless speed change unit The busbars of the disc and the driven cone are logarithmic curves. In the process of speed regulation, both the driving cone and the driven cone must move, and the power roller must rotate and move. Although this traction type continuously variable transmission eliminates the spin, there are two difficulties: one is the complex logarithmic curve of the busbar of the driving cone and the driven cone, which is difficult to manufacture; the other is that the speed control is more troublesome , When the speed is adjusted, the power roller both rotates and moves, and the driving cone and the driven cone will also move along their axis, so the speed control is more difficult.
为了满足汽车对变速器越来越高的要求，迫切需要一种结构简单、制造容易、调速方便的无自旋牵引式无级变速器。In order to meet the higher and higher requirements of automobiles on transmissions, a non-spin traction continuously variable transmission with simple structure, easy manufacture and convenient speed regulation is urgently needed.

第一摆动支座（8a）和第二摆动支座（8b）安装在机架上，它们只能绕大锥齿轮（9）的轴线转动。第一摆动支座（8a）和第二摆动支座（8b）相对于输入轴（1）对称布置。The first swing support (8a) and the second swing support (8b) are installed on the frame, and they can only rotate around the axis of the large bevel gear (9). The first swing support (8a) and the second swing support (8b) are arranged symmetrically with respect to the input shaft (1).

主动滚轮（2）与第一从动锥盘（3a）和第二从动锥盘（3b）在外力的作用下保持接触。接触力可由弹簧力或液压力作用在第一滑块（5a）和第二滑块（5b）上产生。The driving roller (2) keeps in contact with the first driven cone (3a) and the second driven cone (3b) under the action of external force. The contact force can be generated by spring force or hydraulic force acting on the first slider (5a) and the second slider (5b).
无自旋牵引式无级变速器工作时，依靠卷吸作用将牵引油带入主动滚轮（2）与第一从动锥盘（3a）和第二从动锥盘（3b）之间的接触区域，牵引油在接触压力的作用下形成牵引油膜。When the non-spin traction CVT works, the traction oil is brought into the contact area between the driving roller (2) and the first driven cone (3a) and the second driven cone (3b) by means of entrainment , the traction oil forms a traction oil film under the action of contact pressure.
本发明所述的无自旋牵引式无级变速器的动力由输入轴（1）输入，输入轴（1）带动主动滚轮（2）旋转，主动滚轮（2）通过牵引油膜驱动第一从动锥盘（3a）和第二从动锥盘（3b）旋转，第一从动锥盘（3a）和第二从动锥盘（3b）分别带动第一小锥齿轮（7a）和第二小锥齿轮（7b）旋转，这两个小锥齿轮带动大锥齿轮（9）旋转，最后由大锥齿轮（9）将动力输出。The power of the non-spin traction type continuously variable transmission of the present invention is input by the input shaft (1), the input shaft (1) drives the driving roller (2) to rotate, and the driving roller (2) drives the first driven cone through the traction oil film The disk (3a) and the second driven cone (3b) rotate, and the first driven cone (3a) and the second driven cone (3b) respectively drive the first small bevel gear (7a) and the second small bevel When the gear (7b) rotates, the two small bevel gears drive the large bevel gear (9) to rotate, and finally the large bevel gear (9) outputs the power.
在输入轴（1）转速不变的情况下，当主动滚轮（2）沿输入轴（1）移动时，可连续改变大锥齿轮（9）的转速。如果主动滚轮（2）朝远离大锥齿轮（9）的轴线方向运动时，第一中间轴（4a）及其轴上零件绕大锥齿轮（9）的轴线沿逆时针方向转动，第二中间轴（4b）及其轴上零件绕大锥齿轮（9）的轴线沿顺时针方向转动，第一中间轴（4a）和第二中间轴（4b）的夹角变小，大锥齿轮（9）的转速降低。如果主动滚轮（2）朝靠近大锥齿轮（9）的轴线方向运动时，第一中间轴（4a）及其轴上零件绕大锥齿轮（9）的轴线沿顺时针方向转动，第二中间轴（4b）及其轴上零件绕大锥齿轮（9）的轴线沿逆时针方向转动，第一中间轴（4a）和第二中间轴（4b）的夹角变大，大锥齿轮（9）的转速升高。Under the condition that the rotational speed of the input shaft (1) is constant, when the driving roller (2) moves along the input shaft (1), the rotational speed of the large bevel gear (9) can be continuously changed. If the driving roller (2) moves away from the axis of the large bevel gear (9), the first intermediate shaft (4a) and its parts on the shaft rotate counterclockwise around the axis of the large bevel gear (9), and the second intermediate The shaft (4b) and its parts rotate clockwise around the axis of the large bevel gear (9), the angle between the first intermediate shaft (4a) and the second intermediate shaft (4b) becomes smaller, and the large bevel gear (9 ) the speed decreases. If the driving roller (2) moves towards the axis of the large bevel gear (9), the first intermediate shaft (4a) and its parts on the shaft rotate clockwise around the axis of the large bevel gear (9), and the second intermediate The shaft (4b) and its parts on the shaft rotate counterclockwise around the axis of the large bevel gear (9), the angle between the first intermediate shaft (4a) and the second intermediate shaft (4b) becomes larger, and the large bevel gear (9) ) speed increases.

图3为无自旋牵引式无级变速器高速输出的情况。Fig. 3 is the high-speed output situation of the non-spin traction continuously variable transmission.
牵引式传动无自旋现象必须满足的条件是：主动件的回转轴、从动件的回转轴、牵引油膜的切平面三者相互平行或相交于一点。本发明所述的牵引式无级变速器中，主动滚轮（2）的轴线、第一从动锥盘（3a）的轴线、第二从动锥盘（3b）的轴线以及牵引油膜的切平面始终交于一个定点，这个定点就是输入轴（1）与大锥齿轮（9）的轴线的交点。本发明所述的牵引式无级变速器满足牵引传动的无自旋条件，所以不会出现自旋现象，传动具有较高的效率。The condition that the traction transmission has no spin phenomenon must be satisfied: the rotating shaft of the driving part, the rotating shaft of the driven part, and the tangential plane of the traction oil film are parallel to each other or intersect at one point. In the traction continuously variable transmission according to the present invention, the axis of the driving roller (2), the axis of the first driven cone (3a), the axis of the second driven cone (3b) and the tangential plane of the traction oil film are always intersect at a fixed point, and this fixed point is exactly the intersection point of the axes of the input shaft (1) and the large bevel gear (9). The traction type continuously variable transmission of the present invention satisfies the non-spin condition of traction transmission, so the spin phenomenon does not occur, and the transmission has high efficiency.
