Description

Automotive transmission
Technical field
The invention belongs to vehicle transmission part technical field, and in particular to a kind of automotive transmission of new structure.
Technical field
Automotive transmission used in domestic current logistic car, the speed of mostly five speed six, uses input shaft with jackshaft to be upper Lower arrangement, top gear is preceding, and rear, synchronizer is all disposed within output shaft low or first gear, exist total speed than it is small, output shaft is rigid The problems such as difference, amount of deflection are big, hypervelocity shelves gear is fragile, and gear shift is difficult, working strength is big, it is difficult to meet that current logistics automobile is multi-party The fast-developing demand in position.
Therefore, the present inventor designs a kind of 7 grades of automotive transmissions of new structure, thus this case produces.
The content of the invention
It is an object of the invention to provide it is a kind of it is compact-sized, gear is more, ratio coverage is big, matching is reasonable, meshing performance is good, It is cheap, select that gear shift is light, automotive transmission of high reliability.
To achieve these goals, the technical solution adopted in the present invention is：Automotive transmission, including middle tank shell, The procapsid being connected between in front of tank shell, the back casing at tank shell rear is connected between, the automotive transmission is parallel Shaft type drive mechanism, uses output ways of deceleration and output par, c is often engagement；Input axle assembly and jackshaft are horizontal distribution； The speed changer includes input axle assembly, countershaft assembly, export axle assembly, reverse idler gear assembly；The input axle assembly bag Include input shaft, fourth speed gear, the first lock ring type synchronized, the 5th fast gear, the 6th fast gear, the second lock ring type synchronized；
The countershaft assembly include jackshaft, in four travelling gears, in five travelling gears, three forward gears, two Forward gear, a forward gear, shifting gear, the 3rd lock ring type synchronized, the first reverse gear tooth set assembly；
The reverse idler gear assembly is arranged in the input of casing.
Further, wherein middle four-speed gear five fast gears with are fixed on jackshaft by hot jacket, remaining gear passes through Needle bearing is enclosed on input shaft, and synchronizer assembly is fixed on jackshaft by spline.
Further, input axle assembly, countershaft assembly, export axle assembly are supported using multiple bearing, and output shaft passes through circular cone Roller bearing supports.
Beneficial effects of the present invention：
After such scheme, 7 grades of speed changes are realized in the present invention, there is large carrying capacity, compact-sized, numbers of gear steps More, ratio coverage is greatly, matching is reasonable, meshing performance is good, cheap, to various operating modes, road conditions strong adaptability, can preferably expire The growth requirement of the current domestic automobile of foot.
It is furnished with 7 forwards and a reverse gear in the speed changer of the present invention, the three-level for so forming the gear of 4 axle 10 passes Dynamic, 1 astern power exports before realizing 7, and it is 400N.m to form maximum input torque.
Using output ways of deceleration for than conventional input ways of deceleration, advantage in ways of deceleration is exported, Engine torque is input to each gear segment and is not exaggerated, therefore can reduce the size of each gear, under identical input torque, The centre-to-centre spacing of speed changer can be greatly reduced, so as to significantly mitigate weight, reaches light-weighted purpose.

Embodiment
Next with reference to accompanying drawing, the invention will be further described.
As shown in figure 1, the procapsid 1 of present pre-ferred embodiments, a kind of automotive transmission, including interconnection, centre Tank shell 5 and back casing 16, there is input shaft 7, powerdriven output shaft 30 and the centre inputted as power in gearbox Axle 19.
The front end of input shaft 7 is supported on procapsid 1 by the first cylinder roller bearing 2 of the outer ring with locating snap ring, jackshaft 19 are supported on middle shaft housing 5 by the second cylinder roller bearing 6, and rear end is supported on output shaft 14 by needle bearing 15 In endoporus.
Reverse gear on input shaft, one grade, two grades, third gear travelling gear and input shaft design are into a single integrated structure.
Input shaft has fourth speed gear 8, the 5th fast 10 and the 6th fast gear 11 of gear, fourth speed gear 8, the 5th fast tooth 10 and the 6th fast gear 11 of wheel is by needle bearing empty set on input shaft 7.
The first lock ring type synchronized 9 is installed between 8 and the 5th fast gear 10 of fourth speed gear, equally, the 6th fast gear 11 and the 7th are equipped with the second lock ring type synchronized 12 between fast gear.
