1.MT
manual transmission (ManualTransmission, referred to as MT), also known as mechanical transmission, i.e. must manually toggle lever (commonly known as ldquo; Dangba rdquo;) within the transmission to change gears engaged position, change the transmission ratio to achieve the purpose of the transmission. Mostly manual transmission car fourth gear or fifth gear step-gear transmission, and generally with a synchronizer, easy shifting, noise. Manual shift upon actuation of the clutch must be depressed before dial was moving the shift lever.
is a manual transmission with an automatic transmission relative, in fact, occur prior to the automatic transmission cars are all manual transmission. Using manual transmission with gears of different sizes to achieve the shift. The most common manual transmission mostly three to five forward gears and one reverse gear, in a compound transmission used in heavy-duty truck, there are more ratios. The number of so-called transmission gear means the number of forward gears. Generally, transmission efficiency higher than that of a manual transmission of the automatic transmission, and therefore the driver technology is good, manual transmission car to accelerate faster than the automatic transmission vehicle when overtaking also fuel.
Internal structure
shaft
arrangement usually has two-axis shaft and three-axis two kinds. Rear-wheel drive vehicle will usually three-shaft transmission, i.e. an input shaft, an output shaft and the intermediate shaft. The front end of the input shaft by a clutch associated with the engine, an output shaft rear end by a flange associated with the universal transmission. Input shaft and output shaft in the same horizontal line, the intermediate shaft is arranged in parallel with them. The power transmitted to intermediate shaft from the input shaft via a gear and then transmitted to the output shaft. In many transmission input shaft and the output shaft can be joined together, and therefore the power without going through an intermediate shaft, when the gear shift is called directly. Directly by uniaxial gear transmission, the transmission ratio is 1: 1, the highest transmission efficiency. even ifNot in direct gear transmission, the input shaft and the output shaft are arranged in a straight line also help to reduce the work required for the transmission is subjected to a torque.
Reverse apparatus
In response to the stop or other special needs (e.g. quot; narrow passage way quot; … etc.), the reverse gear set, and only in response to a parking stall or other special needs (e.g. quot; narrow passage way quot; …, etc.), in general, the reverse gear ratio are similar with a profile.
The synchronizer
In the synchromesh transmission wherein there is provided a synchronizer, two gears can engage the front speed to achieve the same, such synchronizer are all used in the transmission of a motor vehicle manual transmission
clutches
is the two clutch gears with a separate mechanical part of the binding, binding two gears when the power may be transmitted, no way shift, so the first clutch rely on two separate gears, gear ratio change, and then combining the two gears, power transmission to continue.
actuating means
equipped with a long pole and the first gear position indicative gear, is connected to the transmission lever or play known as gearshift lever (Gearshift lever) typically provided in an intermediate position and center armrest console, some cars are also provided in the steering column of the machine.
gear selector
is generally a manual transmission vehicle speed from ho file. 1 by the gear shift vehicle speed or the lift speed. When the vehicle speed slows down again when the acceleration necessary to retreat many appropriate gear. Flag quot; Rquot; region of the reverse gear. Briefly, when the preceding vehicle forward upshift engine speed high, low engine speed when downshifting. High and low speed of each car is different.
Comparative automatic transmission
The automatic transmission here means a conventional hydraulic automatic transmission, i.e. the power transmitted by the torque converter and the planetary gear the automatic transmission.
advantages
compared with the automatic transmission control can bring more pleasure to the car driving enthusiasts. Transmission efficiency is higher than the automatic transmission, of course, in theory, would be more fuel efficient. It will be cheaper than the automatic transmission on maintenance. If you prefer a higher cost of using automatic manual transmission, you can take into account the convenience of self-discharge and hand row of high efficiency. Engine brake performance is strong.
shortcomings
Some people will feel when driving but also to control the clutch shift is very troublesome. Novice will often stall in the street, especially uphill, improper operation, then have a chance to ruin the engine with gearbox.
