Summary of the invention
The object of this invention is to provide a kind of compact structure, gear is many, ratio coverage is large, coupling is reasonable, meshing performance is good, low price, select that gear shift is light, the automotive transmission of high reliability.
To achieve these goals, the technical solution adopted in the present invention is: automotive transmission, comprise middle box housing, be connected to the front case in middle box housing front, be connected to the rear case at middle box housing rear, this automotive transmission is parallel-axis type drive mechanism, and employing exports ways of deceleration and output is normal engagement; Input shaft assembly and jack shaft are horizontal distribution; Described speed changer comprises input shaft assembly, countershaft assembly, output shaft assembly, reverse idler gear assembly; Described input shaft assembly comprises input shaft, fourth speed gear, the first lock ring type synchronizer, the 5th fast gear, the 6th fast gear, the second lock ring type synchronizer;
Described countershaft assembly comprise jack shaft, in four driving gears, in five driving gears, three advance shifting gears, two advance shifting gears, an advance shifting gear, fall shifting gear, the 3rd lock ring type synchronizer, first reverse gear tooth cover assembly;
Described reverse idler gear assembly is arranged in the input end of casing.
Further, wherein four-speed gear and in five fast gears be fixed on jack shaft by hot jacket, all the other gears are enclosed within input shaft by needle bearing, and synchronizer assembly is built be fixed on jack shaft by flower.
Further, input shaft assembly, countershaft assembly, output shaft assembly adopt multiple bearing supporting, and output shaft is supported by tapered roller bearing.
Beneficial effect of the present invention:
After adopting such scheme, 7 grades of speed changes are realized in the present invention, have that bearing capacity is large, compact structure, numbers of gear steps are many, ratio coverage is large, coupling is reasonable, meshing performance is good, low price, to various operating mode, road conditions strong adaptability, can meet the growth requirement of current domestic automobile preferably.
Be furnished with 7 advance gears and a reverse gear in speed changer of the present invention, form three grades of transmissions of 4 axle 10 gears like this, before achieving 7,1 astern power exports, and forming maximum input torque is 400N.m.
Adopt and export ways of deceleration to than input ways of deceleration in the past, advantage is in output ways of deceleration, Engine torque is input to each gear segment and is not exaggerated, therefore, it is possible to reduce the size of each gear, under identical input torque, the centre distance of speed changer can be reduced greatly, thus significantly weight reduction, reach light-weighted object.
