The invention discloses a track-adjustable vehicle chassis. The vehicle chassis comprises a chassis body and a mounting base, wherein first supports are arranged at the lower ends of the two sides ofthe mounting base correspondingly, belt wheels are rotatably connected to the first supports, the belt wheels are in transmission connection with caterpillar bands, and hydraulic lifting pieces capable of ascending and descending are arranged on the two sides of the upper surface of the mounting base correspondingly; the upper end of the hydraulic lifting part is fixedly connected with the lower end of the chassis. Problems that in the prior art, a chassis of a tracked vehicle is inconvenient to adjust, sludge can contaminate the chassis and even prevent the vehicle from advancing when the tracked vehicle meets the sludge terrain are solved, and the tracked vehicle is advantaged in that the hydraulic lifting part is arranged and can drive the chassis to ascend and descend, and the chassiscan be prevented from being contaminated by a large amount of sludge when passing through the sludge terrain; the hydraulic lifting piece adopting the structure is simpler and easier to maintain, andin one embodiment, the pressing state of the crawler belt can be adjusted by arranging the hydraulic cylinder and the pressing wheel, so different requirements are met.
本发明公开了一种履带可调的车辆底盘,包括底盘和安装座,安装座两侧下端各设置第一支架,第一支架上转动连接带轮,所述带轮上传动连接有履带,所述安装座的上表面两侧均设置有能够升降的液压升降件,液压升降件的上端固定连接底盘的下端。本发明解决了现有技术中的履带车的底盘不方便调节,在遇到淤泥地形时,淤泥会沾染在底盘上,甚至阻止车辆前进的问题,其优点包括,设置了液压升降件,液压升降件可带动底盘升降,底盘上升可避免底盘通过淤泥地形时沾染大量淤泥,使用本结构的液压升降件更加简洁、易于维护,一种实施例中通过设置液压缸和压轮能够实现履带压紧状态的调节,满足不同需要。
