Embodiment Construction

[0032] The specific implementation manner of the present invention will be further described below in conjunction with the six accompanying drawings.

[0033] 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 to realize power transmission.

[0034] Such as figure 1As shown, the schematic diagram of pneumatic shift mechanism and electric clutch system control, the controller directly controls the action of the electric clutch, and the electric clutch also feeds back the clutch signal to the controller; electromagnetic reversing valve I, electromagnetic reversing valve II, electromagnetic reversing valve Ⅲ constitutes the integrated block of electromagnetic reversing valve. The controller directly controls the electromagnetic reversing valve. The cylinder of th...

Abstract

The invention discloses a pneumatic gear shifting system of an automotive mechanical gearbox. The pneumatic gear shifting system of the automotive mechanical gearbox comprises a controller, an electromagnetic reversing valve integrated package, an electric clutch system, a pneumatic gear shifting mechanism, a gear displayer and an electronic gear shifting handle. The electromagnetic reversing valve integrated package is integrated by electromagnetic reversing valves, one end of the electromagnetic reversing valve integrated package is connected with an automobile gas storage tank, and the other end of the electromagnetic reversing valve integrated package is connected with the pneumatic gear shifting mechanism. The electric clutch system is connected with the controller. The controller and the electromagnetic reversing valve integrated package are integrated on a control system of an automobile. The gear displayer is integrated on a display panel of the automobile. The electronic gear shifting handle is arranged in a control area of the automobile. The electric clutch system is fixed to the outer side of the gearbox. The pneumatic gear shifting mechanism is fixed to the gearbox.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a pneumatic shift system of a mechanical gearbox for a vehicle, that is, the shift operation of the mechanical gearbox is realized through a pneumatic 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 the clutch can complete the gear shift. [0003] The gearbox must not only meet the requirements of various road conditions for vehicle driving in terms of mechanical performance to ensure the safe driving of the vehicle, but also meet the user's habits in operation, making the operation comfortable, convenient and has a sense of driving. In order to meet the dual requirements of safe driving and user's operating habits, the invention discloses a pneumatic mechanical automati...
