    摘要: A constant mesh gear transmission has an input shaft (21, 22), two layshafts (31, 35) and an output shaft (23). Gear wheels are selectively connectable to shafts to provide forward and reverse speed ratios. Reverse speed ratio is via a sleeve (85, 86) of a reverse layshaft (35). The sleeve can also re-circulate torque to a forward layshaft (31) to provide an additional low forward speed ratio. Two sleeves and two additional low forward speed ratios are disclosed.
