项目团队自主研发的金属带式无级变速器传动可靠性方法,该方法可被广泛应用于智能车辆节能、车辆环保等先进领域。金属带式无级变速器传动可靠性方法由通过宏微观角度对变速器动力系统失效机理的研究,有效降低功率损失、提高承载能力、减少失效形式。
The transmission reliability method of metal belt-type CVT independently developed by the project team can be widely used in advanced fields such as intelligent vehicle energy saving and vehicle environmental protection. The transmission reliability method of metal belt type CVT is based on the study of failure mechanism of transmission power system from macro and micro angle, which can effectively reduce power loss, improve load capacity and reduce failure mode.

项目方法与现有无级变速器方法的技术指标对比如下:与传统无级变速器传动控制策略相比,通过确定润滑牵引动态平衡阈值,阐明油膜状态与变约束空间动态热力演化的内在联系,构建金属带、带轮轴总成动力学耦合模型,寻求动力学传递路径解耦方法,最终揭示多场耦合作用下动力学系统失效机理,建立系统临界失稳安全域边界,定量化安全裕度。团队研发的方法相较与现有方法,传动效率提高 7.98%9.98%,燃油效率提高 1.15%ECE+EDUC 工况下系统油耗降低约 5.54%。证明该方法具有控制能力强、车辆损耗低、车辆排放降低等优势。
The technical indicators of the project method and the existing CVT method are compared as follows: Compared with the traditional CVT transmission control strategy, by determining the lubrication traction dynamic equilibrium threshold, clarifying the inherent relationship between the oil film state and the dynamic thermodynamic evolution of variable constraint space, establishing the dynamic coupling model of metal belt and belt axle assembly, seeking the decoupling method of dynamic transmission path, finally revealing the failure mechanism of dynamic system under the action of multi-field coupling, establishing the boundary of critical instability safety region of the system, and quantifying the safety margin. Compared with existing methods, the method developed by the team improves transmission efficiency by 7.98%~9.98%, fuel efficiency by1.15%,andfuel consumption of the system under ECE+EDUC conditions by about5.54%. It is proved that this method has the advantages of strong control ability, low vehicle loss and low vehicle emission.

The team has overcome the control method and technology of the transmission reliability of the continuously variable transmission, formed a systematic optimization method, and mastered the core key technology. It has been granted 2 national invention patents, which constructs a relatively complete patent protection layout and provides powerful technical support for the transmission method of metal belt continuously variable transmission to the maximum extent.
