“…The most common CVTs use friction to transmit the torques from one shaft to another. Representative examples are the belt/chain CVT [11], Toroidal CVT [5], [6], Spherical CVT [9], Ball-type CVT [10], etc. In applications where very high powers need to be converted, hydrostatic CVTs are also used [19].…”

Matching motor efficiency and performance with the load demands can significantly improve the overall efficiency of a driveline. Inspired by the automotive sector -with the high interest of hybrid and electric cars currently-, the authors have studied how state of the art technologies can be used in the relatively new field of collaborative and Human centred robotics. Multiple transmission systems have been considered, among others redundant actuators (both static and kinematic) and continuously variable transmissions. Based on these findings and the experience of the research group on customised planetary gear trains for Human Limb Assistance and Replication, an extensive review of existing redundant actuators is presented in combination with an alternative transmission system which does not need any auxiliary gear transmissions and hence can be lighter and more compact than state of the art drivelines for Human centred robotics. A calculation was performed -including the efficiency model presented by Müller- which shows the high potential of this type of dual-motor actuator.

“…CVT telah ditemukan dalam otomotif dan penerapan industri seperti alat permesinan sejak awal abad ke 20. CVT adalah alat transmisi daya, dimana rasio kecepatan dapat divariasi terus-menerus diantara dua batasan [1]. Terdapat banyak jenis dari desain CVT, tiap desain memiliki karakteristik masing-masing, seperti Belt CVT, Spherical CVT [2], Hydrostatic CVT [3], E-CVT [4], Toroidal CVT [5], Power-Split CVT [6], Chain CVT, Milner CVT [7], Ball-Type Toroidal CVT [8], dan sebagainya.…”

The vehicle market in Indonesia, especially motorbikes is very large, it is estimated that the growth of motorbike vehicles will reach 6 million per year. Recently, more than 50 percent is dominated by automatic motorcycles and the market increase significantly. This is because automatic motorcycles can be easily ridden. There are some weaknesses with this transmission system, among them is there is no engine brake when the road is in downhill condition. The motor will easily run when the gas throttle is pressed. This paper discusses the design of a mechanical system on the automatic transmission that is able to prevent mistake on procedures that causes accidents. To achieve this goal, it is necessary to do several steps, including reviewing the existing design, determining the new system, designing the system, manufactured and testing. Experiment results shows that the current motorcycles automatic transmission system can be replaced with a mechatronic system with special linkage mechanism to control ratio change.

“…Traction continuously variable transmission(CVT) is an ideal mechanical transmission device to reduce vehicle emissions, improve the efficiency of the vehicle, and achieve environmental protection [1,2] , because the CVT can provide an infinite number of transmission ratios to allow the engine to operate closer to its optimal efficiency line [3][4][5] . The main principle of power transmitting of traction CVT is shown in Figure 1.…”

In the existing traction continuously variable transmission (CVT), half toroidal CVT (HT-CVT) is considered to have a better traction performance. However, the HT-CVT has the spin losses due to its structural limitations, which significantly influences the traction efficiency. In this paper, the kinematic qualities and contact models of a novel zero-spin rolling conical CVT (RC-CVT) are studied, and then the rollers and conical disks are compactly designed through the proposed design principles. Subsequently, the transmission efficiency is investigated by using a detailed numerical model and compared with HT-CVT. Based on these computational models and parameters, the practical spin ratio, spin momentum and traction efficiency of RC-CVT are calculated and compared with HT-CVT. The results show that the practical spin ratio and spin momentum of RC-CVT are much smaller than that of HT-CVT, and the efficiency on fixed transmission ratio is consequently higher than that of HT-CVT.
