This torque-assist mechanism becomes a torque transfer path during gearshifts, in order to overcome a typical dynamic problem of the AMTs, that is the driving force interruption. The mean power contributions during gearshifts are computed for different engine and ACL interventions, thus allowing to draw considerations useful for developing the control algorithms. The simulation results prove the advantages in terms of gearshift quality and ride comfort of the analysed transmission.

  • MANUAL TRANSMISSION SERVICE Introduction
    MANUAL TRANSMISSION SERVICE Introduction Internal combustion engines develop very little torque or power at low rpm. This is especially obvious when you try to start out in direct drive, 4th gear in a 4-speed or 5th gear in a 6-speed manual transmission -- the engine stalls because it is not producing enough torque to move the load. Manual transmissions have long been used as a method for varying the relationship between the speed of the engine and the speed of the wheels. Varying gear ratios inside the transmission allow the correct amount of engine power to reach the drive wheels at different engine speeds. This enables engines to operate within their power band. A transmission has a gearbox containing a set of gears, which act as torque multipliers to increase the twisting force on the driveshaft, creating a "mechanical advantage", which gets the vehicle moving. From the basic 4 and 5-speed manual transmission used in early Nissan and Infiniti vehicles, to the state-of-the-art, high-tech six speed transmission used today, the principles of a manual gearbox are the same. The driver manually shifts from gear to gear, changing the mechanical advantage to meet the vehicles needs. Nissan and Infiniti vehicles use the constant-mesh type manual transmission. This means the mainshaft gears are in constant mesh with the counter gears. This is possible because the gears on the mainshaft are not splined/locked to the shaft. They are free to rotate on the shaft. With a constant-mesh gearbox, the main drive gear, counter gear and all mainshaft gears are always turning, even when the transmission is in neutral.

  • Development of Hand Control Interface for Manual Transmission Vehicles a Major Qualifying Project WORCESTER POLYTECHNIC INSTITUT
    Project Number: MQP-MQF 3121_ Development of Hand Control Interface for Manual Transmission Vehicles A Major Qualifying Project Submitted to the Faculty of the WORCESTER POLYTECHNIC INSTITUTE In Partial Fulfillment of the Requirements for the Degree of Bachelor of Science in Mechanical Engineering by Zachary Bornemann John LaCamera Leo Torrente Mechanical Engineering Mechanical Engineering Mechanical Engineering MIRAD Laboratory, May 1, 2014 Approved by: Prof. Mustapha S. Fofana, Advisor Director of MIRAD Laboratory, Mechanical Engineering Department Abstract The goal of the MQP was to design and build a minimally invasive hand control interface that can be used by paraplegics or double leg amputees to control manual transmission automobiles. This control interface can also be used by individuals who describe themselves as car enthusiasts and enjoy driving manual transmission vehicles. The primary components of the control interface are mechanical linkages and a steel cable system to actuate the brake and clutch pedals of an automobile. Some products exist that offer control of the gas, brake, and clutch to the user by the means of a hand interface such as the Guidosimplex ‘Duck’ Semi-Automatic Clutch and the Alfred Bekker Manual Hand Clutch, however these products are expensive, invasive, and take away from the full experience of driving a manual transmission of the car. The team conducted analysis of current assistive driving devices, calculated the dynamics of mechanical linkages and steel cables for the brake and clutch systems, and manufactured a prototype control interface. Compared to earlier control interfaces, the team was able to design and build a mechanical control interface with reduced components that offers a tactile response with a simple installation process.

  • Model-Based Control Design and Experimental Validation of an Automated Manual Transmission
    Model-Based Control Design and Experimental Validation of an Automated Manual Transmission THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Teng Ma, B.S. Graduate Program in Mechanical Engineering The Ohio State University 2013 Master's Examination Committee: Dr. Shawn Midlam-Mohler, Advisor Dr. Marcello Canova Copyright by Teng Ma 2013 Abstract With the increasingly rigorous government regulations for fuel economy and exhaust emissions, automotive manufacturers are dedicated to developing vehicles which could have higher fuel economies, lower emissions and at the same time maintain drivability and customer acceptability. Under these demands, automotive manufactures have been developing advanced vehicle powertrains such as hybrid electric vehicle (HEV) and plug- in hybrid electric vehicles (PHEV). This thesis describes the methodology to model and control the linear actuation system of a ‘clutchless’ automated manual transmission (AMT) in a plug-in hybrid electric vehicle, which could improve the drivability and customer acceptability of PHEVs. The ECOCAR 2 architecture adopts the belt coupling between engine and front electric motor, which utilizes the front electric motor to achieve speed matching between the engine and the transmission; so that the AMT in PHEV could realize ‘clutchless’ shifting. The AMT used in this thesis is a modified version of conventional manual transmission which utilizes two linear actuators to move the transmission shifting lever through two cables; therefore, new control method needs to be developed for this system. In order to obtain accurate, fast and robust gear shifting during AMT operation, the control system ii was developed using model-based control theory; with adaptive control algorithm, as well as fault diagnosis.

Figure 1 shows the various types of gears that can be used in a gear train. Gears 2 and 3 can be either spur or helical gears and are mounted on parallel shafts. Gears 4 and 5 are bevel gears that mount on shafts that are 90° apart. Gears 6 and 7 comprise a worm gear set and mount on shafts that are at 90° but are non- intersecting. Worm gears have a high ratio and can be non-reversing. Figure 2 depicts a simple gear train at the top and a compound gear train at the bottom. The simple gear train consists of four in-line gears in mesh. The compound gear train consists of the same four gears, except two are located on the same shaft. The overall ratio of the simple gear train is the product of the three individual ratios and is as follows: n equals the rpm and N equals the number of teeth in the respective gears.
