Description
Technical field
The utility model belongs to the vehicular spare parts technical field, relates to a kind of push-rod assembly, specially refers to the push-rod assembly in a kind of vacuum booster.
Background technology
Prior art, the boost installation that uses in the brake system, after the brake pedal action, after utilizing the connecting rod amplification principle that transmit force is amplified, go to push rod, the piston of push rod by cooperating with head amplifies the rear friction disc brake that passes through again by hydraulic coupling, and push rod is a transition force transmission element in this system.
Existing push rod such as Chinese patent literature data disclose the brake push rod [patent No.: 201020000568.0; Granted publication number: CN201580375U], it comprises the body of rod and square body, is provided with access hole on the square body, the body of rod is welded on the access hole place, and the body of rod is connected mutually with square body.
This kind push rod is by the mode side of being connected body and the body of rod of welding, and is all higher to intensity and the accuracy requirement of position of weld of welding, in case after square body and the body of rod welding, the length of push rod is fixed, can not adjust, can only be installed in the specific system, range of use is less.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides easy to connect and push-rod assembly adjustable in length.
The purpose of this utility model can realize by following technical proposal: a kind of push-rod assembly, comprise the body of rod and jaw, it is characterized in that an end of the described body of rod has external thread section, described jaw is provided with internal thread hole, and the described body of rod and jaw are connected by screw thread.
This push-rod assembly is comprised of the body of rod and jaw two parts, one end of the body of rod has external thread section, and the end that tool internal thread hole on the jaw, the body of rod have external thread section is inserted in the internal thread hole of jaw, the rotation body of rod, regulating pushing rod length, the body of rod and jaw screw thread are connected, this kind push-rod assembly, can regulate according to actual conditions the length of control push rod, to be fit to the demand of vacuum booster in the various different brake system, range of use is wide, and accuracy is high.
In above-mentioned a kind of push-rod assembly, the described body of rod is cylindric, and it is larger to have a diameter of an externally threaded end, and other end diameter is less.The body of rod is staged by the end with external thread section to the diameter of the other end to be dwindled gradually, makes the diameter of the body of rod one end larger, and the diameter of the other end is less, and is rational in infrastructure.
In above-mentioned a kind of push-rod assembly, the end of the other end of the described body of rod is round end.Round end part links to each other with choker relief valve in the vacuum booster, is complementary with the structure of choker relief valve groove, and is rational in infrastructure.
In above-mentioned a kind of push-rod assembly, described jaw is " U " type.The jaw of " U " type is that sheet material advanced punch forming, and wall thickness is thicker, and internal thread hole is offered at the bottom end face center of jaw, is used for linking to each other with the body of rod.
In above-mentioned a kind of push-rod assembly, the week of described internal thread hole is laterally towards jaw " U " type internal protrusion.This kind structure has increased the area of contact of the body of rod and jaw, makes the body of rod and jaw be connected firmly good stability.
In above-mentioned a kind of push-rod assembly, the both sides of described jaw are respectively arranged with a mounting hole.The two sides of " U " type rush respectively a mounting hole, are used for linking with brake pedal.
In above-mentioned a kind of push-rod assembly, described two mounting holes are over against setting.Mounting hole wears for bearing pin, and is rational in infrastructure.
Compared with prior art, the body of rod of a kind of push-rod assembly that the utility model provides and jaw are to be connected by screw thread, can be according to the length of actual conditions regulating pushing rod, to be fit to the demand of vacuum booster in the various different brake system, range of use is wide, and accuracy is high.
Description of drawings
Fig. 1 is the part sectional view of the front view of this push-rod assembly.
Fig. 2 is the lateral plan of this push-rod assembly.
Among the figure, 1, the body of rod; 1a, external thread section; 1b, round end; 2, jaw; 2a, internal thread hole; 2b, mounting hole.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
The push-rod assembly that the utility model provides is a kind of parts of vacuum booster in the brake system, and the one end is connected with the brake pedal lever, and the other end and master brake cylinder link.
As shown in Figure 1 and Figure 2, push-rod assembly comprises the body of rod 1 and jaw 2, the body of rod 1 is by turning and external threading machine-shaping, one end of the body of rod 1 has external thread section 1a, other end diameter along from this external thread section 1a to the body of rod 1 is staged to be dwindled, it is larger to be that the body of rod 1 has the end diameter of external thread section 1a, and the diameter of the other end is less.The other end of the body of rod 1 has round end 1b, and round end 1b is used for linking with the choker relief valve of vacuum booster.
Jaw 2 is " U " type, the dual-side of jaw 2 of the present utility model bends a segment distance towards the center of " U " type, it cuts punch forming by wall thickness than heavy-gauge sheeting, again at internal thread hole 2a of bottom end face car of " U " type, and the circumferential side wall of this internal thread hole 2a is towards the internal protrusion of " U " type jaw 2, this kind structure has increased the area of contact when being threaded, and firmly degree is high.The both sides of jaw 2 arrange respectively a mounting hole 2b, and two mounting hole 2b are over against setting, by wear bearing pin in this mounting hole 2b, brake pedal and push rod are linked.
