6. Friction in elasto hydrodynamically lubricated contacts : the influence of speed and slide to roll ratio
Sammanfattning : Reducing losses in transmissions has become a high priority in the automotive market during recent years, mainly due to environmental concerns leading to regulations placed on the automotive industry to drive the development of vehicles with lower fuel consumption and CO2 emissions. Rising fuel prices and increasing environmental concerns have also made customers more prone to purchase more fuel efficient vehicles. LÄS MER
7. Extended Computational Module for Tractive Effort at Rolling and Spinning Point Contacts
Sammanfattning : One category of mechanical systems that contains power-transferring point contacts is traction drive variators. These variators can be used in different concepts for Continuously Variable Transmissions (CVTs) and in vehicle applications, in order to achieve optimum engine operating conditions leading to improved driveability, reduced fuel consumption and an increase in overall vehicle performance.

8. Tribology of hydraulic motor
Sammanfattning : A radial piston hydraulic motor has several components involving sliding or rolling interfaces which may encounter tribological problems. Seizure is one of them and it results in complete stoppage of motion between the relatively moving components and has serious consequences in terms of the operation of a hydraulic motor. LÄS MER
9. Investigations for enhanced tribological performance of a hydraulic motor
Sammanfattning : A radial piston hydraulic motor has several components that encounter sliding orrolling motion under lubricated conditions. When a hydrostatic, hydrodynamic orelastohydrodynamic oil film separates the interacting surfaces, the wear and frictionare low provided of course the hydraulic fluid is free from the presence ofcontaminants.
