The invention discloses a rubber track chassis system and engineering machinery. The rubber track chassis system comprises a loading wheel set, a guide wheel, a rubber track, a tensioning device and a buffering oil cylinder. The loading wheel set comprises loading wheels and a loading wheel support. And the rubber track is arranged around the outer sides of the loading wheel group and the guide wheel. The tensioning device comprises a tensioning oil cylinder, a tensioning support and a brake arm. A cylinder barrel of the tensioning oil cylinder is connected with the tensioning support, the tensioning support is hinged to the brake arm, and the brake arm is connected with the guide wheel. The buffering oil cylinder is arranged in the tensioning support, the upper end of the buffering oil cylinder is hinged to the tensioning support, and the lower end of the buffering oil cylinder is hinged to the brake arm and the loading wheel support. The upper end of the buffer oil cylinder is hinged to the tensioning support, and the lower end of the buffer oil cylinder is hinged to the brake arm and the loading wheel support to absorb ground vertical load impact transmitted by the loading wheel set, so that the impact resistance of the chassis system in the vertical direction is improved.
本发明公开了一种橡胶履带底盘系统和工程机械。橡胶履带底盘系统包括负重轮组、引导轮、橡胶履带、张紧装置和缓冲油缸,负重轮组包括负重轮和负重轮支架。橡胶履带围绕安装于负重轮组和引导轮的外侧。张紧装置包括张紧油缸、张紧支座和制动臂。张紧油缸的缸筒与张紧支座连接,张紧支座与制动臂铰接,制动臂与引导轮连接。缓冲油缸设置于张紧支座内部,且缓冲油缸的上端与张紧支座铰接,缓冲油缸的下端与制动臂和负重轮支架铰接。本发明的缓冲油缸上端与张紧支座铰接,下端与制动臂和负重轮支架铰接以吸收负重轮组传递来的地面垂直载荷冲击,进而提高底盘系统在垂直方向上的抗冲击能力。
