The invention discloses a vehicle starting and gear linkage device capable of avoiding dangers and a working method thereof. The vehicle starting and gear linkage device comprises an air pocket, a first hand-operated reversing valve, a first pneumatic control reversing valve, an air motor, a second manual reversing valve, an air cylinder and a gear valve, wherein the air pocket is respectively communicated with the first hand-operated reversing valve, the first pneumatic reversing valve and the second hand-operated reversing valve, the first pneumatic control reversing valve is communicated with an air inlet of the air motor, a first one-way valve, a second one-way valve and a second pneumatic control reversing valve are further included, the first hand-operated reversing valve is communicated with the second pneumatic control reversing valve, and the second pneumatic control reversing valve is respectively communicated with an air inlet of the air motor and a control port of the firstpneumatic control reversing valve, the second hand-operated reversing valve is communicated with a rodless cavity of the air cylinder and an air inlet of a first one-way valve, the second hand-operated reversing valve is communicated with a rod cavity of the air cylinder and an air inlet of a second one-way valve, an air outlet of the first one-way valve and an air outlet of the second one-way valve are both communicated with an air control opening of the second air control reversing valve. The vehicle starting and gear linkage device is advantaged in that a vehicle cannot be started when thevehicle is engaged with a forward gear or a backward gear.

    可避免危险的、车辆的启动与档位联动装置及其工作方法,包括气包、第一手动换向阀、第一气控换向阀、气马达、第二手动换向阀、气缸和档位阀;气包分别与第一手动换向阀、第一气控换向阀和第二手动换向阀连通;第一气控换向阀与气马达的进气口连通;还包括第一单向阀、第二单向阀和第二气控换向阀;第一手动换向阀与第二气控换向阀连通,第二气控换向阀分别与气马达的进气口和第一气控换向阀的控制口连通;第二手动换向阀分别与气缸的无杆腔和第一单向阀的进气口连通,第二手动换向阀分别与气缸的有杆腔和第二单向阀的进气口连通;第一单向阀的出气口和第二单向阀的出气口均与第二气控换向阀的气控口连通。本发明可使车辆挂前进档或后退档时车辆不能启动。
