如图3、4、5所示，所述车架上还安装有加载装置，所述加载装置构成施加于所述摩擦负载轮的摩擦负载，可以包括摩擦绳8、过渡轮9和配重单元，过渡轮与车架旋转连接，所述摩擦绳环绕所述摩擦负载轮和所述过渡轮并处于张紧状态，所述摩擦绳在所述过渡轮上绕过的圈数为1-3圈，所述配重单元的上端可通过柔性带固定连接在所述过渡轮的轮面上，配重单元的下端悬空，所述张紧状态是使所述配重单元与所述过渡轮的固定点保持在所述过渡轮的后部半个轮缘表面范围内的张紧程度所对应的张紧状态。设置配重单元以及使摩擦绳处于张紧状态，且摩擦绳在过渡轮上绕过多圈，可有效地保持过渡轮、摩擦绳大体上不随摩擦负载轮的转动而移位，即可以在摩擦负载轮转动时有效地维持摩擦负载轮与摩擦绳之间的相对运动状态和过渡轮与摩擦绳之间的相对静止状态。摩擦绳施加在过渡轮上的合力矩驱使过渡轮与摩擦负载轮同一方向的转动或有转动趋势，该合力矩与摩擦绳和摩擦负载轮之间的摩擦力相关，配重单元施加在过渡轮上的力矩阻止过渡轮的上述转动或转动趋势。在摩擦绳张力一定时，配重单元的重力越大，摩擦绳与摩擦负载轮间的摩擦力越大，即所加载荷越大，被测人体需要克服的阻力矩越大，且成正比关系。As shown in Figures 3, 4, and 5, a loading device is also installed on the vehicle frame, and the loading device constitutes a friction load applied to the friction load wheel, and may include a friction rope 8, a transition wheel 9 and a counterweight unit , the transition wheel is rotatably connected to the vehicle frame, the friction rope surrounds the friction load wheel and the transition wheel and is in a tensioned state, and the number of turns of the friction rope on the transition wheel is 1-3 circles , the upper end of the counterweight unit can be fixedly connected to the wheel surface of the transition wheel through a flexible belt, the lower end of the counterweight unit is suspended, and the tension state is to make the fixed weight unit and the transition wheel The point remains in a state of tension corresponding to the degree of tension within the range of the rear half of the rim surface of the transition wheel. Setting the counterweight unit and keeping the friction rope in a tensioned state, and the friction rope winding around the transition wheel for many times can effectively keep the transition wheel and the friction rope from shifting with the rotation of the friction load wheel, that is, the friction rope can be When the load wheel rotates, the relative motion state between the friction load wheel and the friction rope and the relative static state between the transition wheel and the friction rope are effectively maintained. The resultant torque exerted by the friction rope on the transition wheel drives the transition wheel and the friction load wheel to rotate in the same direction or has a tendency to rotate. The resultant torque is related to the friction force between the friction rope and the friction load wheel. The counterweight unit is applied to the transition wheel The above-mentioned rotation or rotation tendency of the transition wheel is prevented by the torque on the transition wheel. When the tension of the friction rope is constant, the greater the gravity of the counterweight unit, the greater the friction force between the friction rope and the friction load wheel, that is, the greater the applied load, the greater the resistance moment that the measured human body needs to overcome, and the relationship is proportional .
所述摩擦绳的两个端头均固定在所述过渡轮上，其中一个端头在所述过渡轮上绕过一圈以上再固定在所述过渡轮上，由此实现前述的“所述摩擦绳在所述过渡轮上绕过的圈数为1-3圈”，所述摩擦绳位于所述摩擦负载轮和所述过渡轮之间的一个绳段上可设有绳长调节装置。当使用一段时间后，摩擦绳可能出现松懈现象，可以通过调节所述绳长调节装置微调摩擦绳的张紧力。更重要的是，在对功率车进行校准时，可以通过所述绳长调节装置进行微调，使实测功率等于理论计算功率。Both ends of the friction rope are fixed on the transition wheel, and one of the ends goes around the transition wheel for more than one turn and is fixed on the transition wheel, thereby realizing the aforementioned "the The number of turns that the friction rope goes around on the transition wheel is 1-3 circles", and the friction rope can be provided with a rope length adjustment device on a rope segment between the friction load wheel and the transition wheel. After using for a period of time, the friction rope may become slack, and the tension of the friction rope can be fine-tuned by adjusting the rope length adjusting device. More importantly, when the power car is calibrated, the rope length adjustment device can be used for fine-tuning, so that the measured power is equal to the theoretically calculated power.
所述配重单元可以包括单根吊杆101和垂直于所述吊杆的水平托盘102以及若干个重块103，所述吊杆的下端固定在所述托盘的中心，通过将适量的重块放置在水平托盘上实现加载。本实施例中，所述吊杆是一根圆柱形杆，其上部为在该圆柱形柱面上竖向平行切掉两个相对侧平面后形成的形状，设有两个竖直的平行平面1011，所述平行平面的间距小于所述吊杆的直径，所述重块外形是圆柱形，所述重块的中心设有通孔1031，该通孔的直径略大于所述吊杆的直径，以便所述重块能够套在所述吊杆上，所述重块上设有上下贯通的径向延伸的矩形缺口1032，所述矩形缺口的宽度略大于所述吊杆上部两平行平面的间距，以方便将重块套在吊杆上，同时所述缺口的宽度小于所述吊杆的直径，以避免套在吊杆上的重块因非人为因素（例如摩擦式功率车出现摆动或偏斜）从吊杆上脱落。同样的道理，吊杆、重块以及重块上的通孔还可以是其他形状。相比于采用两根吊杆并一左一右分别承载重块的技术手段，本申请采用单根吊杆并使之处于左右对称中心位置，不仅简化了结构，更使得加载变得精确，不会出现像左右分别承载两个/两组重块那样出现左右不平衡等的问题。所述吊杆的上端连接有一个横向连接杆，所述横向连接杆设有对称的两个连接带，所述连接带的下端与所述横向连接杆的相对应端固定连接，上端固定连接在所述过渡轮的轮面的两端上。所述过渡轮的中间设有轮槽，所述连接带的上端分别固定在过渡轮两端的轮面上，即两个直径较大的轮面上，摩擦绳则缠绕在轮槽的槽面上。The counterweight unit may include a single suspender 101, a horizontal pallet 102 perpendicular to the suspender and several weights 103, the lower end of the suspender is fixed at the center of the pallet, and by placing an appropriate amount of weight Placed on a horizontal pallet for loading.

In the same way, the through holes on the suspension rod, the weight and the weight can also be in other shapes. Compared with the technical means of using two suspenders and carrying weights on the left and right respectively, this application adopts a single suspender and makes it in the center of left and right symmetry, which not only simplifies the structure, but also makes the loading more accurate, without There will be problems such as left and right imbalances such as carrying two/two sets of heavy weights on the left and right. The upper end of the boom is connected with a transverse connecting rod, and the transverse connecting rod is provided with two symmetrical connecting bands, the lower end of the connecting band is fixedly connected with the corresponding end of the transverse connecting rod, and the upper end is fixedly connected to the The two ends of the wheel surface of the transition wheel. There is a wheel groove in the middle of the transition wheel, and the upper ends of the connecting belt are respectively fixed on the wheel surfaces at both ends of the transition wheel, that is, the two wheel surfaces with larger diameters, and the friction rope is wound on the groove surface of the wheel groove .
所述摩擦负载轮的轮缘表面优选设有负载槽41，所述摩擦绳绕在所述摩擦负载轮上的部分位于所述负载槽中。一方面，负载槽可有效避免摩擦绳脱离摩擦负载轮，另一方面，仅需要保证负载槽的底面这样一个局部表面的粗糙度情况，即可较好地保证摩擦绳与摩擦负载轮间的摩擦特性。The rim surface of the friction load wheel is preferably provided with a load groove 41, and the part of the friction rope wound on the friction load wheel is located in the load groove.
