A gear shifting valve lock air cylinder is arranged above the mechanical gear shifting handle and is connected with one end of a two-position switching valve, a gear protection unit is arranged on one side of the two-position switching valve, the other end of the two-position switching valve is connected with one end of a two-position solenoid valve, the other end of the two-position solenoid valve is connected with a proximity switch and one end of a pressure reduction valve respectively, a clutch pedal is arranged on one side of the proximity switch, and the other end of the pressure reduction valve is connected with an air source of a whole automobile. According to the device, pneumatic gear shifting is used and is light and effort saving, and dual-protection is arranged, so that abnormal failures caused by mistaken operations, incomplete logic protection and the like are prevented; pneumatic control is performed through electric control, so that the reaction is rapid; mobile elements are all mainstream accessories, so that the device is simple and convenient to maintain.

Description

Two protection ecp gearshifts
Technical field
The utility model relates to two protection ecp gearshifts, belongs to speed changer technical field.
Background technique
Domestic conventional construction speed changer is generally taking armstrong's patent control gear shift as main, and a part heavily blocks speed changer and AMT(mechanical type is automatically controlled) gearbox selector employing gas control.Conventional construction is due to existing problems: 1, manually to control gear shift labor intensity large for speed changer, and travelling comfort is poor; Though 2, some gearshift mechanism adopts compressed-air shifting still due to the protection that do not link, or interlock protection correlation logic does not easily cause speed changer abnormal damage comprehensively; 3, compressed-air shifting structure lacks the stop protection to gear-changing component, lacks locking protection, thereby cause shifting of transmission structure member abnormal damage for misoperations such as exception-triggered.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide two protection ecp gearshifts.
Ecp gearshift of the present utility model, it comprises gear shifting cylinder, reversing air valve, Gear-shift switch, shift valve lock-up cylinder, mechanical type shifting handle, two-position switch valve, gear level protection device, two solenoid valves, clutch pedal, approach switch, pressure loading valve and car load source of the gas, gear shifting cylinder front end is provided with reversing air valve, reversing air valve is connected with one end of Gear-shift switch, the other end of Gear-shift switch is connected with one end of mechanical type shifting handle, the top of mechanical type shifting handle is provided with shift valve lock-up cylinder, shift valve lock-up cylinder is connected with one end of two-position switch valve, one side of two-position switch valve is provided with gear level protection device, the other end of two-position switch valve is connected with one end of two solenoid valves, the other end of two solenoid valves is connected with one end of approach switch and pressure loading valve respectively, one side of approach switch is provided with clutch pedal, the other end of pressure loading valve is connected with car load source of the gas.
The beneficial effects of the utility model: it adopts compressed-air shifting, more Portable power saving, reduce gear shift labor intensity, improve operation comfort, be provided with duplicate protection, avoided due to misoperation and the abnormal failure that reason causes such as virtual protection is not comprehensive; Carry out pneumatic control by automatically controlled, simple and reliable, reflection rapidly; Moving element is all to use main flow accessory, the large reliable performance of market maintenance, convenience easy to maintenance.
