File Name: double reduction and twin speed final drive .zip
This invention relates to a manually operated twin layshaft gear transmission, particularly suitable for front- wheel drive vehicles. Most front-wheel drive vehicles have a transversely mounted engine and transmission for reasons of cost and design efficiency. Almost universally, the transmission is end mounted on the engine, and accordingly it is desirable to minimize the axial length so as not to impede suspension and steering components.

Hydrostatic With Automatic Differential Lock
Like most things on modern automobiles, the simple piece of gearing known as a differential has seen constant refinement and experimentation - leading to a range of types each with their own advantages and disadvantages. The concept of the differential — that is, to allow wheels mounted on the same axle to rotate independently of each other — is an ancient design, with the first known instance of its use recorded in China during the 1 st millennium BC. But this was far from ideal as it meant they were underpowered and encountered frequent problems with traction on anything other than firm, level ground. Eventually this led to the development of the Open Differential before other more complicated types were developed to overcome more complex driving conditions. A differential in its most basic form comprises two halves of an axle with a gear on each end, connected together by a third gear making up three sides of a square. This is usually supplemented by a fourth gear for added strength, completing the square. This basic unit is then further augmented by a ring gear being added to the differential case that holds the basic core gears — and this ring gear allows the wheels to be powered by connecting to the drive shaft via a pinion.
Types of Differential and How They Work
A differential is a gear train with three shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average. The following description of a differential applies to a traditional rear-wheel-drive car or truck with an open or limited slip differential combined with a reduction gearset using bevel gears these are not strictly necessary — see spur-gear differential :. Thus, for example, if the car is making a turn to the right, the main ring gear may make 10 full rotations. During that time, the left wheel will make more rotations because it has farther to travel, and the right wheel will make fewer rotations as it has less distance to travel. The sun gears which drive the axle half-shafts will rotate at different speeds relative to the ring gear one faster, one slower by, say, 2 full turns each 4 full turns relative to each other , resulting in the left wheel making 12 rotations, and the right wheel making 8 rotations.

The tooth design is similar to the spiral bevel but includes some of the characteristics of the worm gear. This permits the reduced drive angle. The hypoid gear teeth have a more pronounced curve and steeper angle, resulting in larger tooth areas and more teeth to be in contact at the same time.
Сьюзан высвободилась из рук обмякшего Хейла, не понимая, что произошло. Стратмор подхватил ее и слегка обнял, пытаясь успокоить. - Ш-ш-ш, - утешал он. - Это .
Ты сочтешь это сумасшествием, - сказал Беккер, - но мне кажется, что у тебя есть кое-что, что мне очень. - Да? - Меган внезапно насторожилась. Беккер достал из кармана бумажник. - Конечно, я буду счастлив тебе заплатить. - И он начал отсчитывать купюры.
