Abstract
Disclosed is a built-in brake spring of a two-stage stroke hydraulic pusher. In a main hydraulic pusher structure formed by a motor seat and a housing, a piston cylinder is arranged between the motor seat and the housing, a piston fixedly connected to a push rod is arranged in the piston cylinder, one end of the push rod extends out of the housing, a solenoid valve 1 is connected between a slot and an oil passage of an oil return chamber in series, and a solenoid valve 2 is connected between a pressure oil cavity and the oil passage of the oil return chamber in series; a spring is arranged between the piston and the inner side of the top of the housing, one end of the spring is connected to the piston in an elastic manner, and the other end of the spring is connected to the inner side of the top of the housing in an elastic manner. Since no additional spring is arranged outside the hydraulic pusher, the outer structure of the hydraulic pusher is simple, and appearance is attractive.
Description
Affiliated technical field
The present invention relates to a kind of hydraulic driver of break, the double-stage stroke hydraulic thruster of brake spring is especially set in inside.
Background technique
At present, known double-stage stroke hydraulic thruster is all need to be at the outside additional brake spring of hydraulic driver, and external brake spring makes hydraulic driver external structure complicated, affects attractive in appearance.
Summary of the invention
In order to overcome existing double-stage stroke hydraulic thruster, use outside additional springs, cause hydraulic driver external structure complicated, affect deficiency attractive in appearance, the invention provides a kind of built-in brake spring of double-stage stroke hydraulic thruster, this built-in brake spring can not only normally provide braking force to hydraulic driver, can also make the external structure of double-stage stroke hydraulic thruster simple, shape is attractive in appearance.
The technical solution adopted for the present invention to solve the technical problems is: motor cabinet and shell, consisting of in hydraulic driver agent structure, piston bore is arranged between motor cabinet and shell, piston is fixedly connected with push rod and is arranged in piston bore, shell is stretched out in one end of push rod, solenoid valve 1 is connected between slotted eye and oil back chamber oil circuit, solenoid valve 2 is connected between pressure oil cavity and oil back chamber oil circuit, between piston and cover top portion inner side, spring is set, one end of spring is connected with piston elasticity, and the other end of spring is connected with elasticity inside cover top portion.
The invention has the beneficial effects as follows, because hydraulic driver outside is without additional springs, hydraulic driver form structure is simple, and shape is attractive in appearance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is circuit theory diagrams of the present invention.
1. push rods in figure, 2. shell, 3. spring, 4. piston bore, 5. piston, 6. motor cabinet, 7. solenoid valve 1, and 8. solenoid valve 2,9. oil back chamber, 10. slotted eye, 11. pressure oil cavities.
