Helical gears in manual transmission are designed based on static loading. Sometimes these gears are subjected to impact during misuse events such as sudden engagement and disengagement of clutches, i....
Many Formula SAE teams choose to design half shafts instead of purchase them. Commercial half shafts are usually over-designed, so teams make custom shafts to reduce the mass and rotational inertia. H....
This paper presents the detailed design of a Single Rail Internal Gear Shift System for a 5-speed manual transmission of a load carrier vehicle. Gear shifting in manual transmissions is achieved by ac....
This paper reviews ratcheting one way clutches (OWC). OWC represent a significant cost in a transmission. Optimizing the OWC type helps reduce cost and increase fuel efficiency, and is therefore worth....
In terms of reducing the gear noise of automatic transmission, improvement of heat treatment distortion of the annulus gear is very important, because annulus gear is very sensitive heat treatment due....
Tolerance stack up is one of the most important exercises of design team to ensure the interchangeability of the components and the sub assemblies in the product having a large product family. Optimiz....
Torsional vibration of drive shaft has great influence on the vibration of vehicle. Reasonable phase arrangement of multi-universal coupling can attenuate vibration. In this paper, theoretical model o....
The performance parameters of torsional vibration damper, including stiffness and damping, have great influence on the torsional vibration of automobile driveline. At present, the research on torsiona....
Torsional vibration dampers are used in automatic and manual transmissions to provide passenger comfort and reduce damage to transmission & driveline components from engine torsionals. This paper will....
Shengrui Transmission Limited Corporate (Shengrui) has developed a new 8 speed automatic transmission (SR 8AT) for front wheel drive (FWD) vehicle. The concept of SR 8AT is unique and different from t....
With the 8HP transmission generation, ZF established a model range on the market offering considerable progress in terms of fuel savings, power-to-weight ratio, and functionality. A front-transverse t....
We have developed the world's first 8-speed automatic transmission for transverse FWD/4WD vehicles. The aim of this new automatic transmission was to achieve world-class fuel economy while offering bo....
The worldwide increasing acceptance and success of modern automatic transmissions in passenger cars is based on innovative technology, driving comfort, shifting dynamic and - most important - fuel con....
The legislative and market pressure for CO2 reduction and fuel efficient powertrains lead to a variety of automatic transmission concepts in recent years. The CVT technology, the dual clutch technolog....
The automotive industry continues to develop new powertrain technologies aimed at reducing overall vehicle level fuel consumption. The ongoing trends of “downsizing” and “down speeding” have led to th....
Two on-line algorithms have been developed to acquire driveline component loads in terms of revolutions at torque and rainflow cycle counting matrix. These algorithms have been implemented in real-tim....
Nowadays, simple shaft and planetary - transmissions are the mostly used type of transmissions in construction machines. They are designed in order to achieve the same number of gear forwards, as well....
This paper defines the shifting quality evaluation index in detail for DCT (Dual Clutch Transmission) from the perspective of control. The vehicle model for DCT is built using MATLAB / Simulink tools,....
Simscape is a physical modeling language developed by Mathworks Inc. The language uses equation statements instead of assignment statements to describe physical systems. The paper focuses on the Simsc....
This paper deals with a mathematical analysis of pump efficiencies in an internal gear and balanced vane pumps. They are commonly used in current automatic transmissions including a continuously varia....
