Problems solved by technology

[0014] However, even if the spring unit is composed of the same components, it is composed of a total of five parts such as the piston seat, the spring, the piston retainer, the rod, and the washer, so the number of parts used as a whole becomes too large. Therefore, not only Increase in product cost due to unit manufacturing cost and assembly cost, and increase in weight due to excessive number of parts
[0015] Especially, in the assembly method of the spring assembly, due to the structure of the piston seat, it can only be assembled with the piston by riveting, so the assembly process of the piston and the spring assembly becomes difficult

Embodiment Construction

[0052] Hereinafter, the embodiments of the present invention will be described in detail with reference to the attached illustrative drawings. Such embodiments are just an example. Since those skilled in the art of the present invention can implement them in various forms, it is not limited to Examples described here.

[0053] figure 1 The structure of the plunger-type master cylinder with a spring assembly according to this embodiment is shown.

[0054] As shown in the figure, the plunger-type master cylinder 1 is composed of: a cylinder block forming a pair of chambers, a main chamber 2 and a floating chamber 3; The main piston 10 of force; the floating piston 20 accommodated in the above-mentioned floating chamber 3; and the cup-shaped oil seal inserted into the cup-shaped oil groove 1a formed on the inner wall surface of the above-mentioned main chamber 2 and floating chamber 3 respectively to form the flow of brake fluid (Seal Cup)4.

Abstract

The present invention relates to a plunger typed master cylinder formed by a master cylinder (10) and floating piston (20) pair, wherein the plunger typed master cylinder comprises springs (12, 22), piston stop collars (13, 23), rods (14, 24) and a spring flange (15c) of piston seats (15, 25), and a spring assembly assembled on the master piston (10) and floating piston (20). And thereby the present invention is characterized by completely removing the difficulty of assembling steps caused by assembling the spring assembly in a manner of riveting, especially reducing a single workpiece manufacturing cost caused by the cancellation of the structure parts of the spring assembly, shortening the assembling steps and also reducing the total weight.

Description

technical field [0001] The present invention relates to a plunger-type master cylinder, and particularly relates to making the assembly of a spring assembly assembled in a piston easy, and besides reducing the single-piece manufacturing cost and shortening the assembly process brought about by reducing the number of parts of the spring assembly, it can also reduce Weight plunger master cylinder. Background technique [0002] Generally, a plunger type master cylinder (Plunger typed master cylinder) uses two pistons to generate oil pressure respectively, and has the advantage of a compact structure because the overall length is shortened compared with a normal master cylinder. [0003] Generally, a piston that receives a force transmitted from a booster (Booster) is called a primary piston, and a piston that operates through the primary piston is called a floating piston. [0004] As other examples with major advantages, the plunger-type master cylinder also has ABS / TCS / ESP i...
