技术领域 technical field
本发明涉及自卸汽车技术领域,尤其是一种铰接式自卸汽车底盘。The invention relates to the technical field of dump trucks, in particular to an articulated dump truck chassis.
背景技术 Background technique
目前载重自卸车底盘主要包括大梁、前车桥、后车桥,大梁是由铰连在一起的前、后车架构成,前车架通过前悬架连接前车桥,后车架通过后悬架连接后车桥,现有自卸车的前、后悬架通过铰接方式与车架连接,虽然能够实现上下跳动和水平摆动,但无法实现各车轮的独立上下跳动,各车桥的摆动幅度较小,特别是在崎岖路面行驶时,车桥对车架施加的各种附加的扭转、弯曲载荷较大,影响车架乃至整车的使用寿命。At present, the chassis of the load dump truck mainly includes the girder, the front axle and the rear axle. The girder is composed of the front and rear frames hinged together. The front and rear suspensions of the existing dump trucks are connected to the vehicle frame through hinged joints. Although the up and down jumps and horizontal swings can be realized, the independent up and down jumps of each wheel cannot be realized, and the swing range of each axle is relatively large. Especially when driving on rough roads, the various additional torsional and bending loads imposed by the axle on the frame are relatively large, which affects the service life of the frame and even the entire vehicle.
申请号为97235741.6的中国专利:“铰接式自卸车底盘”中公开了一种自卸车底盘,该底盘前、后车架通过前、后铰接板和铰接销以及油缸连接,前、后铰接板分别固定在前、后车架上,前、后铰接板的铰接处穿设有竖向的铰接轴,后铰接板与铰接销之间装有圆锥滚子轴承和关节轴承。该自卸车大梁的前、后车架只能在水平面上摆动而不能绕大梁的纵向轴线回转,行走于不平路面时,大梁将受到较大的扭曲变形,这不但会因大梁的设计考虑扭曲变形而增加额外的机构,而且限制了自卸车的机动性能。The Chinese patent application number 97235741.6: "Articulated dump truck chassis" discloses a dump truck chassis, the front and rear frames of the chassis are connected by front and rear hinge plates, hinge pins and oil cylinders, and the front and rear hinge plates are respectively It is fixed on the front and rear vehicle frames, and the hinge joints of the front and rear hinge plates are pierced with vertical hinge shafts, and tapered roller bearings and joint bearings are arranged between the rear hinge plates and the hinge pins. The front and rear frames of the girder of the dump truck can only swing on the horizontal plane and cannot rotate around the longitudinal axis of the girder. And increase extra mechanism, and limit the maneuverability of dump truck.
另外现有自卸车的前悬架多采用油气弹簧,但油气弹簧制造成本高,并且在使用过程中需要一套专门的充气设备维护,按一定的操作规程定期充气,维护保养较麻烦,同时在工作过程中因油缸轴线的偏斜和密封不良,油缸内表面容易刮伤。In addition, the front suspension of existing dump trucks mostly uses oil-pneumatic springs, but the manufacturing cost of oil-pneumatic springs is high, and a set of special inflation equipment is required for maintenance during use. Regular inflation according to certain operating procedures is troublesome for maintenance. During the working process, due to the deflection of the axis of the cylinder and poor sealing, the inner surface of the cylinder is easily scratched.
