CTI Mag: Success opens Doors

An editorial interview with reigning F1 World Champion Nico Rosberg

Obviously I still think a 12-cylinder AMG or Ferrari is brilliant. It gives you goose bumps. But there’s a place for everything, and autonomous driving and electric cars are just as fascinating.

CTI Mag: HOERBIGER SlimLINE creates Space for Hybrid Drives

CTI Mag: HOERBIGER SlimLINE creates Space for Hybrid Drives

Worldwide demand for advanced hybrid technologies for vehicles is growingunabated. These technologies offer a combination of high range, low fuel consumption, and minimal emissions. At the same time, modern combustion engine-based drivetrains leave little room for the integration of additional necessary components. The innovative design of the HOERBIGER SlimLINE synchronizer saves installation space as well as weight and opens up valuable design freedom for hybrid vehicles. Transmission manufacturers can utilize the extra space for an additional electric motor, for example.

CTI Mag: Further CO2 savings thanks to Electric Transmission Oil Pumps

CTI Mag: Further CO2 savings thanks to Electric Transmission Oil Pumps

Conventional, mechanically driven oil pumps must provide the power required under maximum load at each speed in the transmission. In general, under real operating conditions these pumps waste not only valuable energy, but also material and space. Electric oil pumps, on the other hand, provide the power which is actually required at the load points. Further efficiency gains in the transmission are thus possible.

CTI Mag: Hydraulic Accumulator in Transmission Controls

CTI Mag: Hydraulic Accumulator in Transmission Controls

Dual clutch transmissions offering disruption-free traction are in the portfolio of all well-known auto manufacturers. The hydraulic accumulator is the ideal solution to ensure that hydraulic actuations are as efficient as possible even at peak demand. Independent investigations have shown that the hydraulic accumulator makes it possible to gear components, such as the hydraulic pump for actuators, to reduced fuel consumption. This saves energy and reduces CO2 emissions. The hydraulic accumulator needs only about a sixth of energy of a conventional constant pump. Thus, the CO2 emission is reduced by up to 4 g/km.
