The planet row is of an inner engaging mechanism which has the advantage of shortened central distance as compared with external engaging, so that the central distance of the whole transmission is reduced, the space size of the transmission is greatly reduced and the manufacturing cost is reduced by 10%-15%.
Description
Technical field
The invention belongs to automotive transmission structure field, especially relate to a kind of six grades of manual transmissions.
Background technique
In vehicle driving, motor is a link of making power, and clutch is the hinge of transferring power, and speed changer then is the link that is implemented in the distributed power of vehicle under the different running condition.Speed changer is divided into manual transmission and automatic transmission, though that manual transmission is operated is cumbersome, can more directly show driver's wish.
Manual transmission is that the gear train by different tooth ratios constitutes, and its basic functional principle is through switching different gear trains, realizing the conversion of tooth ratio.Gear train is made up of the different gear of diameter, and the different power transmission effects that gear ratios reached are diverse, alleged gearshift change gear ratio just in usual the driving.
At present, at the passenger car of China market, manual vehicle adopts 5 grades of manual transmissions mostly, and promptly direction of advance adds 1 reverse gear shift for 5 grades.And in the passenger car of European market, six grades of manual transmission uses are very general, to such speed changer a lot of design examples arranged.Major part is on the basis of original 5 grades of manual transmissions, to increase synchronizer or adopt double output shaft to realize, belongs to ordinary transmission, complex structure; The use part is many, and transmission efficiency is low, and reverse gear adopts idle pulley to change transmission direction; And use synchronizer; Synchronizer uses too much, causes frictional loss higher, and energy consumption is bigger.
Summary of the invention
The problem that the present invention will solve provides a kind of shifting element, simple in structure, six grades of manual transmissions that transmission efficiency is high of reducing.
For solving the problems of the technologies described above; The claimant is on the basis of studying AT for many years; Textural association in conjunction with three manual transmissions forms; That is: on the basis of common 3 shaft transmissions, increase the planet row that a cover draws the dimension micro-nano structure, make it use minimum part to realize 6 gears, structure is driven for vertical postpone.Reverse gear directly by planet row output, has reduced shifting element simultaneously, has reduced loss, has reduced fuel consume.
Advantage and good effect that the present invention has are:
1, tradition adopts 7 cover constant mesh gears for 6 grades, and this programme number of spare parts is few, adopts 4 cover constant mesh gears, and number of spare parts significantly reduces.
2, the quantity owing to constant mesh gear reduces, thereby has increased substantially transmission efficiency.
3, the common manual speed changer adopts reverse gear synchronizer and reverse idler gear, and this programme has been cancelled synchronizer and reverse idler gear because planet row can directly export reverse gear, has reduced cost, has improved transmission efficiency.
4, this scheme is owing to adopted La Weinashi planet row, and compact structure is compared the space of having shortened speed changer greatly with the conventional manual speed changer.
5, because planet row for interior engaging mechanism and outer gearing reduced in comparison centre distance, thereby shortened the centre distance of whole speed changer, reduced the volume and weight of speed changer.
6, owing to the quantity that has reduced part, so manufacture cost has approximately reduced 10%-15%.
