The gear ratio is the ratio between the input and output gears. The driving gear and driven gears in a gearbox define the gear ratios. The input gears get the engine’s drive and rotate the output gears, which, in turn, drive the wheels. The ratio of the number of rotations of output...
grt = Gear ratio transmission grd = Gear ratio differential ve = Engine speed vc = Vehicle speed Tire size calculatedDiameter = [ Width · Profile / 100 · 2 ] / 25.4 + Wheel size ] · 25.4 Note: The height of the tire represents 1/2 of the tire. The tire is a donut shape, ...
The transmission has a plurality of members that can be utilized in powertrains to provide at least eight forward speed ratios and one reverse speed ratio. The transmission includes
Vehicle speed sensor (VSS)- The vehicle speed sensor measures the output shaft speed of the transmission and is used to determine shift points and calculate torque converter clutch slip. On four wheel drive vehicles, the VSS is located through the transfer case, while two wheel drive vehicles h...
A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated friction torque elements to effect gear
PURPOSE:To increase the degree of freedom of selection of a gear ratio without increasing the number of fastening elements by a method wherein eight members rotatable relatively to each other comprises seven rotary members containing input and output shafts and one stationary member, e.g. a case...
The gearshift device comprises a clutch (2) which is arranged -between the driving engine (1) and the change-speed gear m transmission (3). The gear ratio which is favourable for the actual running condition is determined in connection w... SCHWEIGER, KLAUS, FRIEDRICHSHAFEN, DE - DE 被引...
2.1.2Line Chart Analysis Method New transmission schemes can be inspired through analysis of the relative rotational speed relationship of each basic component of a scheme [5], as shown in Fig.2. By determining the sequence of the gear ratio, all possible gears can be found. Auxiliary componen...
FIG. 3 is a gear ratio chart showing ratios as well as clutch and brake activation patterns for each gear in accordance with the transmission of FIG. 2; FIG. 4 is a power flow diagram showing the power flow in the transmission of FIG. 2 in a 1 F configuration; FIG. 5 is a power...
The 10R140 features 10 forward gear ratios, which translates into small steps between gears (25% on average) and an ideal gear ratio for any terrain and any situation. Most importantly, the small gear steps keep the engine within an ideal operating range, maximizing available torque and elimin...
