摘要
针对小型赛车动力转向机构存在的结构复杂、响应不及时、成本高等问题,提出一种以超声电机为动力源的小型赛车动力转向结构.在机构优化设计基础上,对超声电机响应时间进行理论推导和计算,并对电机驱动转向器齿轮机构进行仿真分析,结果表明,设计的新型转向机构符合赛车技术要求,相较于传统电磁电机助力,其结构更简单、驱动响应速度更快,从而使赛车具备了更灵敏的操纵性能,提升了赛车的过弯能力.
In order to solve the problems of power steering mechanism of racing car,such as complex structure,untimely response and high cost,a power steering structure of racing car with ultrasonic motor as power source is proposed.On the basis of mechanism optimization design,the response time of the ultrasonic motor is theoretically deduced and calculated,and simulation analysis is carried out on the motor driven steering gear mechanism.The results show that the new type of steering mechanism designed is in conformity with the technical requirements for the racing car.Compared with the traditional steering gear power,its structure is more simple,and the driving response is faster,so that the racing car has more sensitive control performance and better cornering ability.
