技术领域technical field
本发明涉及车辆调速技术领域,具体涉及一种调速器及调速装置。The invention relates to the technical field of vehicle speed regulation, in particular to a speed regulator and a speed regulation device.
背景技术Background technique
在现有技术中,如图1所示,电动车一般是通过调速装置将车辆驱动电机的动力输出主轴11’与车轮的中心轴即从动轴21’相连。该调速装置包括主动轮组1’、从动轮组2’和皮带3’,如图2所示,主动轮组1’包括套在驱动电机主轴11’上的定轮12’和动轮13’,定轮12’和动轮13’的背部相向可以嵌进一根皮带3’,定轮12’固定在主轴11’的端部,动轮13’可以沿主轴11’的轴线方向作少量位移。如图3所示,从动轮组2’包括套设在车轮的从动轴21’上的第一从侧轮22’和第二从侧轮23’,第一从侧轮22’和第二从侧轮23’的背部相向可以嵌进上述皮带3’,第一从侧轮22’固定在从动轴21’的中部,第二从侧轮23’可沿从动轴21’的轴线方向做轴向移动,并且第二从侧轮23’的一侧配置有提供轴向压力的弹簧24’。In the prior art, as shown in Fig. 1, the electric vehicle generally connects the power output main shaft 11' of the vehicle drive motor to the driven shaft 21', which is the central axis of the wheel, through a speed control device. The speed regulating device includes a driving wheel set 1', a driven wheel set 2' and a belt 3'. As shown in FIG. 2, the driving wheel set 1' includes a fixed wheel 12' and a driving wheel 13' sleeved on the main shaft 11' of the driving motor. A belt 3' can be embedded in the back of the fixed pulley 12' and the moving pulley 13' facing each other. The fixed pulley 12' is fixed at the end of the main shaft 11', and the moving pulley 13' can make a small amount of displacement along the axis of the main shaft 11'. As shown in FIG. 3 , the driven
如图2所示,主动轮组1’中的动轮13’背部的凹盘131’内设有多条滚道132’,滚道132’内低外高成斜坡状,分为三级均匀分布在其圆周上,多个离心滚柱133’分别装在各滚道132’中,由卡盘134’压住。当驱动电机主轴11’转动时,离心滚柱133’便受到离心力,随着转速升高离心力增大,离心滚柱133’在离心力的作用下便沿动轮13’上的滚道132’向外飞开,由于卡盘134’是固定在主轴11’上不动的,它和动轮13’内侧滚道132’的斜坡共同作用下,离心滚柱133’将动轮13’推移,将皮带3’向外挤出,又由于主动轮组1’与从动轮组2’的中心距不变,因此迫使从动轮组2’的第二从侧轮23’压缩弹簧24’向外移动,使第一从侧轮22’和第二从侧轮23’之间的间隔拉大,减小从动轮组2’的工作直径,这样主动轮组1’工作直径逐渐变大,从动轮组2’工作直径逐渐变小,使传动比逐渐变小,实现了从低速到高速的无级变速传动。反之,当驱动电机转速下降时,由于离心滚柱133’受到的离心力减小,这时动轮13’的轴向推力也减小,动轮13’反向移动,主动轮组1’工作直径减小,这时第二从侧轮23’在弹簧24’的作用下向内移动,将皮带3’向外挤出,使从动轮组2’的工作直径增大,使传动比逐渐变大,实现了从高速到低速的无级变速传动。As shown in Fig. 2, a plurality of raceways 132' are arranged in the concave disc 131' on the back of the driving wheel 13' in the driving wheel set 1'. On its circumference, a plurality of centrifugal rollers 133' are respectively installed in each raceway 132' and pressed by a chuck 134'. When the main shaft 11' of the driving motor rotates, the centrifugal roller 133' is subjected to centrifugal force. As the rotational speed increases, the centrifugal force increases. Under the action of the centrifugal force, the centrifugal roller 133' moves outward along the raceway 132' on the driving wheel 13'. Fly away, since the chuck 134' is fixed on the main shaft 11', it and the slope of the inner raceway 132' of the driving wheel 13' work together, the centrifugal roller 133' pushes the driving wheel 13' and pushes the belt 3' Extruded outward, and since the center distance between the driving wheel set 1' and the driven wheel set 2' remains unchanged, the second secondary side wheel 23' of the driven wheel set 2' is forced to move outwardly by the compression spring 24', so that the first The interval between the slave side pulley 22' and the second slave side pulley 23' is increased, and the working diameter of the driven pulley 2' is reduced, so that the working diameter of the driving pulley 1' gradually increases, and the working diameter of the driven pulley 2' It gradually becomes smaller, so that the transmission ratio gradually becomes smaller, and the continuously variable transmission from low speed to high speed is realized. Conversely, when the rotational speed of the driving motor decreases, the centrifugal force received by the centrifugal roller 133' decreases, and the axial thrust of the driving wheel 13' also decreases, the driving wheel 13' moves in the opposite direction, and the working diameter of the driving wheel group 1' decreases. At this time, the second slave side pulley 23' moves inward under the action of the spring 24', and the belt 3' is extruded outward, so that the working diameter of the driven pulley group 2' is increased, and the transmission ratio is gradually increased. Continuously variable transmission from high speed to low speed.
但是上述现有技术中的调速装置属于被动调速,传动比的变化依赖于主轴11’的转速,无法实现传动比可调可控的主动调速。However, the speed regulating device in the above-mentioned prior art belongs to passive speed regulation, and the change of the transmission ratio depends on the rotational speed of the main shaft 11', and cannot realize the active speed regulation with adjustable and controllable transmission ratio.

为了便于描述,在这里可以使用空间相对术语,如“在……之上”、“在……上方”、“在……上表面”、“上面的”等,用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是,空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如,如果附图中的器件被倒置,则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而,示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位),并且对这里所使用的空间相对描述作出相应解释。For ease of description, spatially relative terms, such as "on", "over", "on the surface", "above", etc., may be used herein to describe what is shown in the figures. The spatial positional relationship of one device or feature shown to other devices or features. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or features would then be oriented "below" or "over" the other devices or features under other devices or constructions". Thus, the exemplary term "above" can encompass both an orientation of "above" and "below." The device may also be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein interpreted accordingly.
此外,需要说明的是,使用“第一”、“第二”等词语来限定零部件,仅仅是为了便于对相应零部件进行区别,如没有另行声明,上述词语并没有特殊含义,因此不能理解为对本发明保护范围的限制。In addition, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood to limit the scope of protection of the present invention.
