Abstract

The invention discloses an electronic shifting system of a vehicle mechanical gearbox. The electronic shifting system of the vehicle mechanical gearbox comprises a controller, an electric hydraulic pump, an electric pushing rod pump, an electronic shifting handle, a brake pedal and a power source. The electric hydraulic pump and the electric pushing rod pump are controlled by the controller. The electric hydraulic pump is connected with a clutch. The electric pushing rod pump is connected with a gear selecting and shifting mechanism. According to the electronic shifting system of the vehicle mechanical gearbox, a manual operation rod on a manual gearbox is changed to an electric pushing rod so that electric shifting operation can be achieved; a clutch pedal mechanism is changed to the electric hydraulic pump so that automatic clutch operation can be achieved; the electronic shifting handle (or a knob) is additionally arranged, so that individualized shifting operation is achieved and adaptability is enhanced; the controller is additionally arranged, so that smooth shifting and interactive processing of relevant information are achieved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an electronic shifting system of a mechanical gearbox for a vehicle, that is, the gearshift operation of the mechanical gearbox is realized through an electronic control system. Background technique [0002] At present, urban vehicles such as buses and taxis mostly use mechanical gearboxes. The installation and manufacturing costs of mechanical gearboxes are low and the fuel consumption is low. However, when shifting gears in mechanical gearboxes, the clutch must be disengaged first, then the shift handle must be pulled, and then the clutch should be engaged. Wait for a series of operations to complete the shift. Urban traffic conditions are complex, taxis and buses shift gears very frequently, and drivers are labor-intensive. At present, although the AT automatic transmission technology is mature, it is very expensive and has high fuel consumption, which is about 20% higher than that ...
