Abstract
The utility model relates to a spring component applied to a plunger type brake master cylinder, and belongs to the technical field of automobile brakes. Piston springs are connected to the outside of a first spring limiting base and the outside of a second spring limiting base in a sleeved mode, the first spring limiting base is connected with a hanging-connecting head end of a spring limiting rod through a complete round hole in the first spring limiting base in an inserted mode, the other end of the spring limiting rod is in rivet connection with a complete round hole in the second spring limiting base through a riveting point, a small washer is located between the second spring limiting base and the riveting point, and the height H of the riveting point is equal to 1.3+/-0.2 mm. The spring component has the advantages that the structure is novel and simple, the two spring limiting bases can be stamping parts, machining difficulty is low, and manufacturing cost is low; the spring component is high in strength, the riveting point is formed in a riveting mode, accordingly, strength of the spring component is superior to that of spring components formed in other modes, and pulling-out force of the spring component is not less than 2000N; dimensional accuracy and efficiency during assembly are high.
Description
Technical field
The utility model belongs to automobile brake technical field, is particularly useful for plunger-type brake master cylinder.
Background technique
Brake master cylinder is the critical component in brake system of car, and its Main Function is that the piston in the displacement promotion master cylinder being moved by pedal moves and produces hydraulic pressure, thereby realizes braking action.In recent years, plunger-type brake master cylinder can meet the requirement of brake fluid flow that vehicle is larger, large stroke and large discharge capacity because of it, and the advantage that obviously reduces than traditional master cylinder (center valve type and compensation cellular type) of apparent size, and extensive use in braking system.Plunger typed master cylinder is mainly made up of Master cylinder body, sealing cup, piston and spring members, and wherein spring members mainly plays a part to connect and resetting piston.
Current spring members medi-spring position-limited lever is entered spring position limit socket center and is articulated with it by the skewed slot A that runs through on spring position limit socket, there is following shortcoming in such structure, owing to running through the existence of skewed slot, cause spring position-limited lever easily to be deviate from work or have abnormal sound, and on circular spring position limit socket, output run through skewed slot also cause spring members bulk strength decline.
Summary of the invention
The utility model provides a kind of spring members that is applied to plunger-type brake master cylinder, the problem of easily deviating from work or having abnormal sound, spring members bulk strength to decline to solve the spring position-limited lever of depositing in spring members.
The technological scheme that the utility model is taked is: piston spring is socketed in spring position limit socket one and spring position limit socket two outsides, spring position limit socket one is pegged graft by the head end that articulates of the complete circular hole on it and spring position-limited lever, complete circular hole on the other end of this spring position-limited lever and spring position limit socket two is put riveted joint by riveting, small washer between spring position limit socket two and riveting point, this riveting point height H=1.3 ± 0.2mm.
The utility model has the advantages that novel structure, succinct, two spring position limit sockets can be stamping part, and difficulty of processing is little, low cost of manufacture; Spring members intensity is high, forms riveting point by riveted joint, makes the intensity of spring members be better than alternate manner, and its pulling-out force is not less than 2000N; Fitted position precision and efficiency are high, and this spring members structure can be followed the stroke requirement according to master cylinder, accurately guarantee parts overall height L, in can be controlled in ± 0.2mm of its tolerance; And in also can control ± 0.2mm of riveting point height H.

Embodiment
Piston spring 2 is socketed in spring position limit socket 1 and spring position limit socket 25 outsides, spring position limit socket 1 is pegged graft by the complete circular hole 101 on it and the head end 301 that articulates of spring position-limited lever 3, complete circular hole 501 on the other end of this spring position-limited lever 3 and spring position limit socket 25 is put 302 riveted joints by riveting, small washer 4 between spring position limit socket two and riveting point, this riveting point height H=1.3 ± 0.2mm.
Piston spring is by two ends, two spring position limit socket location, and spring position limit socket one is identical with spring position limit socket two structures, and spring position-limited lever passes two spring position limit sockets, and at one end packs into after small washer, rivets rear formation spring members by riveting press.
Claims (1)
1. one kind is applied to the spring members of plunger-type brake master cylinder, piston spring is socketed in spring position limit socket one and spring position limit socket two outsides, it is characterized in that: spring position limit socket one is pegged graft by the head end that articulates of the complete circular hole on it and spring position-limited lever, complete circular hole on the other end of this spring position-limited lever and spring position limit socket two is put riveted joint by riveting, small washer between spring position limit socket two and riveting point, this riveting point height H=1.3 ± 0.2mm.
