Abstract:
A suspension system, which relates to the fields of engineering machinery and automobiles and is used for adjusting a tilting posture of a cab. The suspension system comprises a first cross beam (1), second cross beams (2), a first support (3), a second support (4), a first connecting rod (5), a second connecting rod (6), a third connecting rod (7), a first oil cylinder (8) and a second oil cylinder (9). The second cross beams (2) and the first cross beam (1) are arranged in a spaced manner. The first support (3) is mounted at one end of one of the second cross beams (2). The second support (4) is mounted at the other end of the other of the second cross beams (2). One end of the first connecting rod (5) is rotatably connected to one end of the first cross beam (1). One end of the second connecting rod (6) is rotatably connected to the other end of the first cross beam (1). The first oil cylinder (8) is mounted between the first connecting rod (5) and the third connecting rod (7). The second oil cylinder (9) is connected between the second connecting rod (6) and the third connecting rod (7). The tilting posture of the cab is controlled by means of the suspension system, thereby achieving an autonomous adjustment of the tilting posture of the cab. The present invention further relates to an engineering vehicle and a suspension system control method.
