Embodiment Construction
[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be pointed out that the scope of protection of the present invention is not limited to the following embodiments. Retouching should be regarded as the scope of protection of the present invention.
[0027] see figure 1 , figure 2 , The invention discloses an oil-pneumatic torsion spring, comprising a cylinder barrel (4), a torsion shaft (2), a floating piston (6) and an end cover (1). The cylinder (4) is cylindrical, and is designed with a cylinder center shaft (14), one end of the torsion shaft (2) is designed as a counterbore, and the other end is a torsion shaft swing arm (10), and a damping hole is opened on the swing arm (11), and is coaxially installed in the cylinder barrel (4) through the counterbore, and the cylinder barrel (4) is divided into two symmetrical parts. The floating piston (6) is symmetrically install...

The invention discloses an oil gas torsion spring. The oil gas torsion spring comprises a cylinder barrel, a torsion shaft, floating pistons and an end cover. The cylinder barrel is cylindrical and is provided with a cylinder barrel center shaft. One end of the torsion shaft is provided with a counterbore and coaxially arranged on the cylinder barrel center shaft in a sleeving mode through the counterbore, the cylinder barrel is divided into two symmetric parts, the other end of the torsion shaft is provided with a torsion shaft swing arm, and a damping hole is formed in the swing arm. The floating pistons are symmetrically installed in the cylinder barrel in a floating mode and divide the cylinder barrel into two symmetric gas chambers and two symmetric oil chambers. The gas chambers are filled with inert gas, and the oil chambers are filled with hydraulic oil. Through holes are formed in the end cover and penetrate through the torsion shaft to be fixedly connected with the cylinder barrel through bolts. The oil gas torsion spring has non-linear torsion rigidity and damping characteristics, the torsion rigidity and the damping coefficient can be automatically adjusted, and therefore torsion vibration is effectively buffered and attenuated.
Description
technical field [0001] The invention relates to the field of shock absorbers, in particular to an oil-pneumatic torsion spring Background technique [0002] Most of the current torsion springs are mechanical torsion bar springs and helical torsion springs. The stiffness of traditional torsion springs is usually linear and cannot be adjusted; the damping coefficient is uncertain and cannot effectively dampen vibrations; at the same time, traditional torsion springs are all mechanical torsion springs, which are prone to noise during operation. Contents of the invention [0003] The object of the present invention is to provide an oil-gas torsion spring that can realize automatic adjustment of nonlinear torsional stiffness and damping coefficient, can reduce vibration and noise, can be installed at any angle, and has greater adaptability. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solution...
