Figure 1 It is the structural schematic diagram of the hydraulic operating clutch mechanism for motorcycle engine of the utility model.
[0013] Reference signs are explained: rubber cap 1, hydraulic exhaust screw plug 2, oil passing bolt 3, copper washer 4, shell 5, hydraulic ram 6, steel ball 7, hole stop ring 8, sealing ring I 9, sealing ring II 10 and spring 11. DETAILED DESCRIPTION
[0014] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, in which similar parts are denoted by the same reference signs in the following text.
[0015] Figure 1 The structural schematic diagram of one embodiment of the hydraulic operating clutch mechanism for motorcycle engine of the utility model is shown. In this embodiment, a clutch hydraulic actuator includes rubber cap 1, hydraulic exhaust screw plug 2, oil passing bolt 3, copper washer 4, shell 5, hydraulic ram 6, steel ball 7, hole stop ring 8, sealing ring I 9, sealing ring II 10 and spring 11. Rubber cap 1 is assembled at the head of hydraulic exhaust screw plug 2, the front section of hydraulic exhaust screw plug 2 is provided with threads, which are threadedly connected with the head of oil passing bolt 3, the middle of oil passing bolt 3 is a through hole, and the side surface is provided with an oil hole, the front section is provided with threads, and is connected into shell 5 through threaded connection. Oil passing bolt 3 and copper washer 4 are connected with oil pipe through compression sealing. Hydraulic ram 6 is integrally assembled inside shell 5, steel ball 7 is assembled above hydraulic ram 6, spring 11 is assembled below hydraulic ram 6, the inner side of shell 5 is provided with stop ring groove, and hole stop ring 8 is assembled.
[0016] The hydraulic plunger 6 is provided with two annular grooves outside, and sealing ring I 9 and sealing ring II 10 are arranged in the annular grooves, the outside of the sealing ring I 9 and the sealing ring II 10 is in interference fit with the inner wall of the shell 5, the sealing ring I 9 is arranged on the upper side of the hydraulic plunger 6, and engine oil is sealed, and the sealing ring II 10 is arranged on the lower side of the hydraulic plunger 6, and brake fluid is sealed.
