Milestone knowledge cup chamber structure of master cylinder for vehicle

摘要

The present design is that, in general, both sides of the master cylinder (5) constituting a vehicle brake unit (1) first and second piston on the oil Oriental knowledge keopsil structure respectively disposed on the piston side of the predetermined area of ​​the master cylinder constituting a vehicle brake unit rubber type fitted in each of a predetermined portion of (13, 14) keopsil 16, the rubber keopsil equation 16 is due to that is provided to structural weakness in the vehicle braking device if it is desired to be such that the fixed contact is in position ultimately, in order to solve the problem that causes the brake function is lowering of the vehicle as (1) continuing the rubber expression by the repeated load or offset load of the use keopsil 16. this causes flow of the vehicle brake unit (1) side of the brake pedal 2 side booster unit each of the first and second pistons (13, 14) which is provided to the inside of the master cylinder 5, which are mutually connected to (3) constituting the rubber type keopsil ( The first of the master cylinder (5) constituting a vehicle brake unit (1) being 16), the body part 17 the inner circumferential surface 360 ​​continuous to be provided at a predetermined interval respectively to be a compression spring member 18 is inserted into a predetermined portion of the forming, as the second piston (13, 14) side respectively of the rubber formula keopsil 16 able to be fixed to be a more close contact with the effect that enables the braking performance it can be maintained properly.
