CLAMPING AND SEALING METHODS FOR SOLENOID VALVE IN HYDRAULIC UNIT AND CLAMPING AND SEALING STRUCTURES THEREOF AS WELL AS SOLENOID VALVE ASSEMBLING JIG IN ADDITION TO ANTISKID BRAKING SYSTEM

摘要

PURPOSE: To secure a hydraulic unit and an antiskid braking system compact in size and lighter in weight as well as to provide such a jig as optimum for assembling a solenoid valve to a storage case. ;CONSTITUTION: A member in an inner circumferential part of a storage hole part 28 of a storage case 3 is fluidified by plastic deformation and stuck close to two grooves 51, 52 of each outer circumferential part of two solenoid valves 1 and 2 just as plastic bonding, thus they are joined together in a state that a residual stress at the time of being plastically deformed is left behind. In consequence, the solenoid valves 1, 2 and the storage case 3 are firmly secured to each other after being sealed up. Therefore, strength in a cover 4 becomes disused, whereby all bolts for cover locking use can be miniaturized and reduced, thus miniaturization and lightweightiness for a hydraulic unit and an antiskid braking system are well promoted so far as a portion for that. Moreover, owing to a jig 7 consisting of a temporary clamping part 8 and a pressing part 9, assembling of these solenoid valves 1, 2 to the storage case 3 for those of hydraulic unit and antiskid braking system becomes facilitated.;COPYRIGHT: (C)1994,JPO&Japio
