The invention relates to an agricultural four-wheel-drive self-adaptive chassis with a rigidity-adjustable damping mechanism. The agricultural four-wheel-drive self-adaptive chassis comprises a vehicle body and an independent suspension system. The vehicle body comprises a vehicle body and a rack; the independent suspension system comprises suspension damping devices arranged on the front side and the rear side of the vehicle body. The suspension damping device comprises a suspension device and a damping device. The suspension device comprises a parallel four-bar profiling mechanism; the damping device comprises a spring damping shock absorber and an air spring system; the air spring system comprises an air spring, an additional air chamber, an inflator, a height adjusting valve and a connecting pipeline; the upper end of the spring damping shock absorber is hinged to a vehicle body, and the lower end of the spring damping shock absorber is hinged to a first connecting rod in the parallel four-rod profiling mechanism. According to the agricultural four-wheel-drive self-adaptive chassis, the trafficability of an agricultural unmanned vehicle is improved, meanwhile, the impact of an uneven road surface on a vehicle body can be reduced, and the application range of the agricultural unmanned vehicle is widened.

    本发明涉及一种具有可调刚度减振机构的农用四驱自适应底盘,包括车体和独立悬架系统;所述车体包括车身和机架;所述独立悬架系统包括设在车体前后两侧的悬架减震装置;所述悬架减震装置包括悬架装置和减震装置;所述悬架装置包括平行四杆仿形机构;所述减震装置包括弹簧阻尼减震器和空气弹簧系统;所述空气弹簧系统包括空气弹簧、附加气室、充气机、高度调节阀和连接管路;所述弹簧阻尼减震器的上端与车身铰接,下端与所述平行四杆仿形机构中的第一连杆铰接。本发明的农用四驱自适应底盘在提高农用无人车通过性的同时,可降低不平路面对车身的冲击,提高农用无人车适用范围。
