The purpose of the utility model is to realize like this; A kind of hydraulic locking apparatus; Comprise pull bar, it is characterized in that: also comprise piston and piston cylinder and form oil pocket, said pull bar is arranged in the said piston and two ends are connected with said piston cylinder with smoothing roll respectively; Said piston is provided with binding ring A and is connected with the binding ring B contact that is arranged on said smoothing roll collars fit on; Said pull bar is elongated under the effect of hydraulic oil, through rotate said binding ring A can make its with said binding ring B card with or stack, thereby produce or remove coupling mechanism force.
Said binding ring A is the internal spline shape, and said binding ring B is the external splines shape, and the two can block and or stack.
Said binding ring A and said binding ring B contact-making surface place are provided with groove.
Establish support bar, spring and baffle plate B in the said binding ring A and be close to through said support bar, spring and baffle plate B and said piston cylinder.
Said pull bar peripheral hardware lining and through the applying of said lining and said smoothing roll is provided with alignment pin between said lining and the said smoothing roll.
Said pull bar also is provided with lock sleeve and passes through said lock sleeve and lining and said smoothing roll fastening outward.
The outer baffled A of said piston and fix through said baffle plate A and smoothing roll.
