The invention discloses a variable range driving mechanism of an engineering vehicle. The variable range driving mechanism comprises a linkage wheel rocker, a main adjustment connecting rod, a main variable range oil cylinder, a main adjustment rocker, an auxiliary variable range oil cylinder and a plurality of follow-up connecting rods; the linkage wheel rocker is hinged to wheels; the auxiliary variable range oil cylinder and the main adjustment rocker are hinged to a vehicle body; the main variable range oil cylinder and the auxiliary variable range oil cylinder are hinged to the main adjustment rocker; the main adjustment rocker is hinged to the main adjustment connecting rod; the main adjustment rocker and the main adjustment connecting rod are hinged to the linkage wheel rocker through the plurality of follow-up connecting rods to form a two-degree-of-freedom variable range driving mechanism. According to the variable range driving mechanism of the engineering vehicle, the complex mechanism path of the wheel gravity is implemented through the movement of the variable range driving mechanism to enable the adaptability of the vehicle to the terrain to be enhanced and meanwhile the purposes of shock absorption and improvement of the comfort are achieved due to the real-time response of the variable range driving mechanism to the height of the ground.
Description
technical field [0001] The invention relates to an engineering vehicle, in particular to a vehicle luffing drive mechanism. Background technique [0002] Construction machinery needs a certain degree of stability during operations. When the vehicle passes through rough and uneven roads, it is required that the vehicle can keep the center of gravity of the operation stable. [0003] It is difficult for the construction machinery chassis in the prior art to meet the above requirements. Contents of the invention [0004] The object of the present invention is to provide a luffing drive mechanism for engineering vehicles, which can reduce the impact force on the wheels, ensure the stable posture of the working chassis, and enhance the passing performance and obstacle-surpassing ability. [0005] The purpose of the present invention is achieved through the following technical solutions: [0006] The engineering vehicle luffing drive mechanism of the present invention comprise...
