Abstract

The invention provides a hydraulic cylinder with the quick-start starting characteristic. The hydraulic cylinder mainly comprises an end cover A, an end cover B, a cylinder barrel, a guide sleeve, a piston rod, a piston, a cushion collar A and a cushion collar B and is characterized in that the cushion collars with the isosceles trapezium cross sections enable the hydraulic cylinder to present the 'early quick-late slow' characteristic during starting. Through the cushion collar A and the cushion collar B, of which the head end cross sections are shaped like isosceles trapeziums, the purpose that the hydraulic cylinder has the quick-start characteristic during starting and does buffering motion during stopping; and through double oil grooves and double seal rings, temporary storage of leaked oil and sealing of the piston are realized.

Description

technical field [0001] The present invention relates to a hydraulic cylinder with a quick-opening characteristic when starting, and in particular to a buffer sleeve A and a buffer sleeve B with an isosceles trapezoidal cross-section at the head end, so that the hydraulic cylinder exhibits a quick-opening characteristic when starting and a quick-opening characteristic when stopping. It is a cushioning movement; the temporary storage of oil leakage and the sealing of the piston are realized through double oil tanks and double sealing rings, which belongs to the technical research and development field of hydraulic cylinders. Background technique [0002] The hydraulic cylinder converts hydraulic energy into mechanical energy by using the linear reciprocating motion of the piston, but due to the singleness of the current hydraulic cylinder structure, some special applications cannot be realized. For example, in a certain working condition, the hydraulic cylinder needs to be abl...
