Performance Analysis Of Gearbox

Ningbo Xinhong Hydraulic Co.,Limited | Updated: Sep 04, 2017

      Transmission is used to change the speed and torque from the engine mechanism, it can be fixed or shift the output shaft and input shaft transmission ratio, also known as the gearbox. The transmission is made up of variable-speed transmission mechanism and control mechanism, and some cars have power output mechanism. The transmission mechanism mostly uses the ordinary gear transmission, also some uses the planetary gear transmission. General gear transmission mechanism with sliding gear and Synchronizer.Gearbox

     When the relationship between the tooth number of the driven gear and the tooth number of the active gear changes, the ratio i changes, under the condition that the engine speed is invariable, it will affect the output shaft speed change, that is, the wheel speed change. A pair of meshing gears, the use of the number of teeth will not change, so its ratio is fixed. If the number of gears on the input axis with several teeth number and the corresponding teeth on the output shaft is also a change of gear meshing, then a set of different transmission ratio I can be obtained. The car gearbox is based on this basic principle to achieve shift speed.Gearbox

     A forward stall that allows the car to move forward. Reverse the gears that drive the car backwards. Gap, transmission gears are not in the work position, at this time the engine power input to the input shaft, no longer to the output shaft transmission. Direct file. Engine power does not pass through the transmission of any gear transmission, but by the transmission input shaft and directly connected to it as one of the output shaft directly output of the stall is called a direct file. The direct gear ratio is 1.Gearbox

     Number of stalls. Refers to the number of stalls that have a class gear transmission. Commonly used gear transmissions are four to five gears, and three-shift transmissions are rare. The more gears, the better the adaptability of the vehicle to the driving conditions, the lower the fuel consumption, but the more complicated the transmission mechanism and the manipulator, the harder the operation and the higher the cost. Low-grade, high-grade. Gearbox

     In the transmission stalls, the number of small stalls called low-grade, the smaller the number of stalls, the greater the transmission ratio, the greater the traction, and the lower the speed. such as the transmission ratio in the forward position of the largest, the lowest speed, the largest traction. Large number of stalls called high-grade, the larger the number, the smaller the transmission ratio, the smaller the traction, but the higher the speed.Gearbox
