Abstract

The invention provides a hydraulic cylinder capable of being started under assistance of waste energy. The hydraulic cylinder mainly comprises a cylinder barrel, end covers, a piston, a piston rod, a guide sleeve, a butter plate and a spring; the end covers comprise the end cover A and the end cover B; and the hydraulic cylinder is characterized in that waste energy generated after the piston stops moving is stored and converted into kinetic energy for assisting starting. Through the buffer plate with the spring, buffer static motion, waste energy storage and starting assistance of the piston are achieved; through an arc-shaped groove in the buffer plate, pressure balance of the two sides of the buffer plate is achieved; through a sealing ring on the outer side of the piston and an oil storage groove in the inner side of the piston, sealing and leaked oil temporary storage of the piston can be achieved.

Description

technical field [0001] The present invention relates to a hydraulic cylinder that utilizes waste energy to assist in starting, in particular to a buffer plate with a spring to realize the cushioning of the piston, store waste energy and assist its start; through the arc groove on the buffer plate, the buffer The pressure on both sides of the plate is balanced; through the sealing ring on the outside of the piston and the oil storage tank on the inside, the sealing of the piston and the temporary storage of oil leakage are realized, which belongs to the technical research and development field of hydraulic cylinders. Background technique [0002] The hydraulic cylinder uses the linear reciprocating motion of the piston to convert hydraulic energy into mechanical energy. When the piston changes from motion to rest, it needs to consume its kinetic energy, such as converting the kinetic energy of the piston into the thermal energy of hydraulic oil, so as to make the piston statio...
