KTH230 is a dedicated hybrid transmission with energy saving and high efficiency, multi gear and multi-mode, high integration and low cost. The dual motor integrated oil cooling design integrated hybrid box can save more than 40% oil. The overall performance of the product is superior, especially in reducing fuel consumption. Under NEDC conditions, the fuel saving rate of the whole vehicle is 35% ~ 45%, and the fuel consumption per 100 km can be reduced to 4.6L. By simplifying the overall structure, modular integration and other forms, compact and light weight can be realized, and the manufacturing cost can be further optimized, which is more than 20% lower than the manufacturing cost of the mainstream hybrid transmission in the market. The product can realize the platformization, and can match the car, SUV, pickup and other types of models. Through the power compensation ability of the motor, the power interruption and NVH problems in the shifting process are improved, the frustration is reduced, the product performance is improved, the mileage anxiety and battery life are eliminated, and the driving experience is more comfortable.

 

  

EDS

坤泰车辆EDS是一款三合一纯电动系统,主打以电机、电控、减速箱一体化设计,定义了坤泰三合一系统平台,实现同一技术,多个产品。产品高度集成,通过减少连接件,取消冗余件,降低成本,同时总体体积降低20%,功率密度达到1.9Kw/Kg。驱动系统的NEDC综合效率可达88%,最高效率超过92%。采用扁线电机,槽满率、NVH、散热性能大幅提升,提高功率密度,电机最高效率达到97.2%。采用高重合度的齿轮副设计方案,在高达12100rpm下,系统依然可以保持优异的NVH效果。

采取自主研发EDS控制模型,基于EDS结构、整车动力性、经济型等要求进行了详细的控制策略设计,实现电机、减速箱等相关附件控制,满足现阶段以及未来油耗要求。

 

Kuntye’s EDS is a 3in1 pure electric system, which is mainly based on the integrated design of motor, electronic control and gearbox. It defines Kuntye’s 3in1 system platform, which realizes the same technology and multiple products. By reducing connectors and eliminating redundant parts, the product is highly integrated and the cost is reduced. Meanwhile, the overall volume is reduced by 20%, and the power density reaches 1.9kw/kg. The overall efficiency of NEDC can reach 88%, and the highest efficiency is over 92%. With flat wire motor, the slot full rate , NVH and heat dissipation performance are greatly improved and the maximum efficiency of the motor reaches 97.2%. By using the gear pair design scheme with high coincidence, the system can still maintain excellent NVH effect at up to 12100rpm.            The independent research and development of EDS control model is designed based on the EDS structure, vehicle power performance, economy and other requirements, so as to realize the control of motor, gearbox and other related accessories, and meet the current and future fuel consumption requirements.

 

DCT

坤泰的7DCT是一款坤泰自主研发的、结构紧凑、效率更高的新一代湿式7速双离合变速箱,产品通过集成化设计,解决客户空间不足、油耗高的焦虑,助力整车性价比提升。  

相比其他AT、CVT类型变速箱,有更宽的齿比跨度(7.5)、可向更大速比范围、更多档位及P2混动或者四驱结构拓展,在减重、改善NVH、搭载布置等方面都非常有优势。

产品采用窄齿宽、细高齿设计,紧凑的空间设计优于同级合资竞品,轴向尺寸可达365mm;中心距低至190mm;输入输出轴高低差可降至65mm;采用模块化、集成化设计,可应用于A-B级整车平台的车型搭载;采用轻量化设计,重量低至80kg,同时多档位、宽的速比范围(7.5)设计,可以更好的匹配发动机工作特性使发动机在转速区域持续高效,传动效率高达97%。产品可匹配搭载离心摆式减振飞轮,使发动机运转转速降低至1200rpm以下,运转噪音更安静,静谧的噪音控制,变速器齿轮噪音低于76分贝。

 

Kuntye's 7DCT is a new generation of wet 7-speed dual clutch gearbox independently developed by Kuntye with compact structure and higher efficiency. Through integrated design, the product solves customers' anxiety of insufficient space and high fuel consumption, and helps to improve the cost performance of the whole vehicle.            

Compared with other AT and CVT transmissions, it has a wider gear ratio span (7.5), and can expand to a larger speed ratio range, more gears and P2 hybrid or four-wheel drive structure. It has great advantages in weight reduction, NVH improvement, carrying arrangement, etc.

The product adopts narrow tooth and fine high tooth design, and its compact space design is superior to the joint venture products of the same level, with axial dimension up to 365 mm. The center distance is as low as 190mm and the height difference of input and output shafts can be reduced to 65 mm. Modular and integrated design is adopted, which can be applied to the vehicle carrying of class A-B vehicle platform.  Adopting lightweight design, the weight is as low as 80kg, and the multi gear, wide speed ratio range (7.5) design can better match the working characteristics of the engine, making the engine continuously efficient in the speed region, and the transmission efficiency is as high as 97%. The product can be equipped with a centrifugal Pendulum damping flywheel to reduce the engine speed to less than 1200rpm and make the running noise quieter. The noise of the transmission gear is less than 76dB.
