Abstract
The utility model discloses a novel pin shaft and aims to solve the problem that abnormal sound may come out, when a clutch pedal arm is connected with the shift fork of a clutch master cylinder via a pin shaft. The novel pin shaft comprises a block, a shaft body and a lock hole, wherein the block is arranged on one end of the shaft body, the lock hole is arranged on the other end of the shaft body, and a plastic sleeve is arranged on the shaft body. The novel pin shaft is easy for manufacture and installation, low in cost and excellent in application effect.
Description
Technical field
The utility model relates to a kind of automobile machinery part, particularly relates to the bearing pin that a kind of automobile clutch pedal arm is connected with clutch master cylinder shift fork.
Background technique
The clutch pedal arm is connected by bearing pin with clutch master cylinder shift fork, and bearing pin and link are all metal material, when vehicle movement or the pedal action time will produce the abnormal voice of intermetallic bump, friction.For eliminating this phenomenon, be simple approach to bearing pin transformation.
In the prior art, to the transformation of bearing pin, the purpose of innovation all is to concentrate on the bearing pin function, such as strengthening anti-shear ability, add large bearing capacity, be easy to dismounting and transform or the like, the technology that makes it to be used to reduce the noise aspect by transformation for how but is difficult to inquiry.Be called the Chinese patent of " connection bearing pin " as publication No. CN101725599A name, a kind of bearing pin that has from the dismounting function is provided, be applicable to the connection of large-size components.Its innovation purpose is to make bearing pin be convenient to dismounting, and only is suitable for the connection of large component such as crane arm etc.
The model utility content
Occur the technical problem of abnormal voice after the utility model purpose is to solve existing in prior technology clutch pedal arm and clutch master cylinder shift fork is connected by bearing pin, provide a kind of no abnormal sound, use, easy for installation, novel bearing pin simple in structure.
The problems of the prior art are mainly solved by following technical proposals: a kind of novel bearing pin, comprise block, axis body, lockhole, and block is at an end of axis body, and lockhole is at the other end of axis body, and axis body is provided with plastic sheath.Bearing pin is loaded onto after the plastic sheath, connects to no longer include metal behind clutch pedal arm and the clutch master cylinder shift fork and contact with the direct of metal, but the contacting of plastics and metal, and therefore, has eliminated the abnormal voice when using former bearing pin.
As preferably, the material of plastic sheath is a polyoxymethylene.Polyoxymethylene abbreviates POM as, has mechanical strength height, good rigidly and higher plurality of advantages such as fatigue resistance, is commonly called as plastic-steel, is very suitable for using on the bearing.
As preferably, for drive fit is connected, can avoid the wearing and tearing that relatively rotate between bearing pin and the plastic sheath between plastic sheath and the bearing pin, can make again between bearing pin and the clutch pedal arm and carry out close fit.
As preferably, the length of plastic sheath is identical with axis body length, and plastic sheath thickness is smaller or equal to 1 millimeter.Last worker's difference is 0, and following worker's difference is 0.1 millimeter.
The beneficial effect that the utility model brings is, solved the clutch pedal arm and the technical problem of abnormal voice occurred after clutch master cylinder shift fork is connected by bearing pin, and make simple, cost is low, easy for installation, using effect is good.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Among the figure: the 1st, block, the 2nd, axis body, the 3rd, lockhole.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, a kind of novel bearing pin comprises block, axis body, lockhole, and block is at an end of axis body, and lockhole is placed plastic sheath at the other end of axis body on the axis body.Bearing pin is processed by low-carbon alloy steel, man-hour the diameter of axis body is shortened 2 millimeters and reserve plastic sheath thickness adding, make the axis body radius add plastic sheath thickness and equal required bearing pin radius, the POM plastic sheath that with thickness is 1 millimeter (going up worker's difference is 0, and following worker's difference is 0.1 millimeter) afterwards is fixed on the axis body in the drive fit mode.
During application bearing pin is put into the link pin shaft hole, in the lockhole of bearing pin, put into cotter pin bearing pin is locked.
The utility model the clutch pedal arm with use during the clutch general pump shift fork is connected after solved the technical problem of abnormal voice, and have and make the features such as simple, that cost is low, easy for installation, and result of use is good.
