Embodiment Construction

[0026] Attached below Figure 1-5 A specific embodiment of the present invention will be further described.

[0027] The power transmission structure in the technical solution of the present invention is the same as the power transmission structure of the manual gearbox, that is, the power transmission is transmitted from the engine to the transmission, and then to the output component, realizing the direct transmission of power.

[0028] Such as figure 1 As shown, the control schematic diagram of the electronic shifting system.

[0029] The electronic shifting system of a mechanical gearbox for a vehicle, the electronic shifting system of the mechanical gearbox includes a controller, a gas-electric combined pump, an electric push rod pump A, an electric push rod pump B, an electric push rod pump C, a gear Display, electronic shift handle or electronic shift knob, brake pedal, power supply.

[0030] The power supply provides power for the controller, and at the same time, t...

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, a pneumatic-electric united pump, an electric pushing rod pump and an electronic shifting handle. The pneumatic-electric united pump and the electric pushing rod pump are controlled by the controller. The pneumatic-electric united 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 pneumatic-electric united 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. A series of operations such as manually engaging the clutch can complete the gear shift. [0003] 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 of a mechanical transmission, and the maintenance cost is high. Therefore, AT automatic transmissions are more common in m...
