Truck automatic vehicle transmission 9JSS series

■Twin countershaft in main case and tri-countershaft in auxiliary case; power split, large load capacity and high reliability. ■Mainshaft and gears on it are floating, no needle bearings between gears and shaft and high efficiency in power transfer . ■Gears adopt thin-and-fine teeth design (contact ratio ε>2), smooth engagement and low noise. ■Lock-pin synchronizer in auxiliary case, high-performance & non-metallic friction material for friction taper surfaces and high reliability ■Large range of gear ratios meets different road conditions with strong climbing ability . ■Combined design of main and auxiliary cases, small ratio steps and good fuel-efficiency . ■A variety of forms for power taking-off meet the power-output demands of all refitted trucks. ■Single H or double H, single-lever or double-lever operating mechanism can be realized.
