What The Function and Usage of Manual Gearboxes?
In you car, the manual gearbox will generally be connected to the engine and form one unit supported by mounting. The manual gearbox for the front wheel drive is located on the left or right hand side of your car. The output or the power the manual gearbox is transmitted via the four, five or six forward speed and reverse to drive shaft, to one or more differentials, which in turn drive the wheels. The manual gearbox converts engine speed into torque which will push the car forward.
How The Gears Function Inside The Manual Gearbox Gears ?
Your car engine torque is transmitted by using the clutch to the input shaft through any gear has been engaged, to the output shaft. The output shaft forward gears witch are helically cut, are in constant mesh with corresponding gears on the input shaft. When the gear level is introduce to operate, is to change the gears. The forward gears are selected involving what is called synchronise rings and hubs. Using the gear level to change to the higher gear, the synchro rings is pushed towards the gear and onto the gear cone via the blocker bars.
The faster rotating gear of the input shaft, to be reduce to the speed of the output shaft and permitting the gears to be changed this operation is caused by the ring friction cone.
When you change the gear down, the slower rotating gear is accelerated in the same way at the higher gear. The reverse gear fitted on the input shaft and has straight cut teeth and run the first, second gear located on the output shaft through an idler gear.
How The Output shaft Torque Function
The output shaft torque is transmitted to the differential drive gear, in-cased to the differential carrier, and through the differential drive pinion gears to the front drive shaft cv’s joint. The differential carrier, the taper roller bearings are pre-loaded by two diaphragm springs that have different external diameters. They are complicated adjustment procedure must done. You get this information later.
Gear Lever Function
Your vehicle gear lever and linkage are connects with the selector mechanism inside your gearbox casing. An axial and rotary movements of the control shaft are transmitted through a selector block which is in-cased to the control shaft and two guide levers to the guide shaft. The linkage and the gear lever has a selector block which is rotated and axially displaced.
The rotary movement involves meshing of a cam on the guide shaft selector block with either the first/second selector fork, the third/fourth selector fork or reverse guide lever recess.
The axial movement of the shaft causes the appropriate fork to be displaced on the selector shaft or the reverse idler gear to be displaced via the guide lever thereby engaging the required gear. Some precaution is made for locking the gear engaged, that mean the gear selector block and the plate carried on the guide shaft selector block and a spring loaded interlock pin.
This is the view of the gears inside your manual gearbox after removing the casing. The components of the gearbox gearing consist of (Reverse idler gear- Circlips-input shaft and gear cluster- Main shaft-large ball bearing- Small Ball Bearing-Ball bearing- Synchroniser rings- 4th gear- Synchroniser Spring- 3th/4th Synchroniser- 3th/4th Gear Selector- 3th Gear- Retaining Ring- Half thrust Rings- 2nd Gear- 1st/2nd Gear Synchroniser Hub- 1st/2nd Gear Selector Ring With Reverse Gear- 1st gear- Mainshaft-Oil Slinger). Now, you going to save money and understand the repairs and what are the components should be changed when you have problems with your gearbox manual.
