近几年, 我国专用车迅猛发展, 对汽车取力器的需求日益增大。特别是水泥搅拌运输车,需要连续工作较长时间, 就要选择功率较大、能连续运转的取力器。发动机取力器有利于整车布置，而成为这些车辆的首选。 In recent years, with the rapid development of special vehicles in my country, the demand for automotive power take-offs is increasing day by day. Especially for cement mixer trucks, which need to work continuously for a long time, it is necessary to choose a power take-off with higher power and continuous operation. The engine power take-off is beneficial to the layout of the whole vehicle and has become the first choice for these vehicles.
混凝土搅拌运输车采用发动机取力方式，取力器取出发动机动力，经泵转化为液压能，再经马达输出为转速和扭矩，为搅拌筒转动提供动力。 The concrete mixer truck adopts the power take-off method of the engine, and the power take-off takes out the engine power, which is converted into hydraulic energy by the pump, and then output as speed and torque by the motor to provide power for the rotation of the mixing drum.
16~20m3的大型混凝土搅拌运输车备受用户青睐，发动机取力器需要输出更大的扭矩，发动机取力器与使用工况不匹配而导致发动机取力器使用寿命缩短, 甚至造成严重的质量事故, 给改装厂家及用户带来了诸多不便并造成经济上的损失。针对这些情况, 验证运转可靠，能够持续输出大扭矩的取力器装置已引起业界人士的关注。 16~20m 3 large concrete mixer trucks are favored by users. The engine power take-off needs to output more torque. The engine power take-off does not match the working conditions, which will shorten the service life of the engine power take-off, and even cause serious damage. Quality accidents have brought a lot of inconvenience to refit manufacturers and users and caused economic losses. In view of these situations, it has been verified that the power take-off device with reliable operation and continuous output of high torque has attracted the attention of people in the industry.

Wherein, shaft coupling 4 is a double shaft coupling.
采用本装置试验前，需要采用常规发动机的安装形式对发动机边界控制条件进行试验获得，即发动机先在常规的试验台架上对发动机多个工况点进行测试，测量发动机的中冷后进气温度、排气背压、冷却水量等相关参数，然后再利用这些相关参数应用在本技术方案中，通过空压机加载控制装置对多个工况点进行试验，获得发动机取力器的试验边界条件，最后选择合适的发动机取力器，按照发明具体实施。 Before using this device for testing, it is necessary to use a conventional engine installation form to test the boundary control conditions of the engine, that is, the engine is first tested on a conventional test bench for multiple operating points of the engine, and the intake air after the intercooling of the engine is measured. Temperature, exhaust back pressure, cooling water and other related parameters, and then use these related parameters to apply in this technical solution, and test multiple working condition points through the air compressor loading control device to obtain the test boundary of the engine power take-off Conditions, finally select a suitable engine power take-off, according to the specific implementation of the invention.
考虑到搅拌车驱动载荷变化主要表现在扭矩的变化，取力器随搅拌筒工况不同其扭矩变化，试验的控制程序可以根据搅拌车取力器实际运行的工况编订试验工况，考核工况由加料程序、运行程序、换向工序、卸料工序、空载返回不同工况进行试验；同时将空压机的加载装置能与发动机工况保持同步，共同实现了台架控制。 Considering that the change of the driving load of the mixer truck is mainly reflected in the change of the torque, and the torque of the power take-off varies with the working conditions of the mixing drum, the control program of the test can be compiled according to the actual operating conditions of the mixer truck power take-off.
