Description

Multifunctional bushing

Technical Field

The utility model belongs to commercial car spare part field, especially a multifunctional bushing.

Background

With the rapid development of the automobile industry in China, the requirements of people on the comfort, safety and reliability of automobiles are higher and higher. The structural design of the automobile is also refined from a rough type. Automobile pedals are important tools for drivers to transmit instructions, and fine and perfect design is further required.

The conventional bushing structure is mainly composed of a boss portion and a skirt portion; the bushing has no functions of compensating clearance and eliminating interference fit, if the clearance between the shaft and the shaft tube is too small, the bushing is easy to block, so that the movement resistance of the pedal is large, the bushing is seriously abraded, and the service life is greatly shortened; if the clearance between the shaft and the shaft tube is too large, the lining is easy to loosen and abnormal sound causes the pedal to loose and shake.

Disclosure of Invention

To the technical problem, the utility model provides a multi-functional bush has effectively solved bush fit-up gap's problem.

In order to solve the technical problem, the technical scheme of the utility model is that: a multifunctional bushing includes an integral bushing body composed of a boss portion and a skirt portion, characterized in that: the inner circumference of the wall of the boss part is distributed with a plurality of first cavities extending along the axial direction of the boss, the outer side surface of the boss part is circumferentially distributed with a plurality of reinforcing ribs extending along the axial direction of the boss, and the outer side surface of the skirt part is circumferentially distributed with a plurality of second hole cavities extending along the radial direction of the boss.

The technical scheme is further improved, and a plurality of small salient points are distributed on the binding surface of the skirt part.

The technical scheme is further limited, the bushing body, the reinforcing ribs and the salient points are of an integral structure and are made of POM materials.

The utility model discloses beneficial effect: 1) the first cavity structure on the boss part enables the interference in the radial direction of the assembly of the shaft and the shaft tube to be eliminated, the problem of pedal assembly locking is solved, the assembly efficiency is greatly improved, and meanwhile, the treading force is moderate when a driver drives, and the comfort is provided; 2) the arrangement of the reinforcing ribs enables the radial clearance to be compensated, and simultaneously enhances the strength of the bushing, so that the service life of the bushing is prolonged, the shaft tube is not easy to shake and is tightly matched; 3) the second cavity structure on the skirt portion enables the axial assembly interference magnitude of the shaft and the shaft tube to be eliminated, and the problem of axial assembly tightness is solved.

Detailed Description

As shown in fig. 1 and 2, the multifunctional bushing comprises an integral bushing body consisting of a boss part 1 and a skirt part 2, wherein nine first cavities 101 extending along the axial direction of a boss are distributed on the inner circumference of the wall of the boss part, and the radial thickness of each first cavity is 1.3 mm;

as shown in fig. 1 and 2, nine reinforcing ribs 102 extending axially along the boss are circumferentially distributed on the outer side surface of the boss portion; each first cavity corresponds to one reinforcing rib, so that when the shaft tube and the central shaft are assembled, if the radial clearance is insufficient, the cavities can be extruded, the bushing is uniformly and tightly contacted with the central shaft of the shaft tube, and the condition of assembly clamping is avoided; if the clearance between the shaft tube and the central shaft is too large, the reinforcing rib can compensate the size of a part, and the loosening risk is eliminated;

as shown in fig. 1 and 2, nine second holes 201 extending along the radial direction of the boss are distributed on the outer side surface of the skirt part along the circumference, and the design is to eliminate the axial clearance, when the axial clearance between the shaft tube and the shaft is insufficient, the skirt cavity can be squeezed, the over-tight assembly is avoided, the pedal is not flexible to move, and the comfort of a driver is affected;

as shown in fig. 1 and 2, a plurality of small salient points 3 are distributed on the binding surface of the skirt part, and the salient points solve the problems of insufficient friction force and easy slipping and falling;

the bushing body, the reinforcing ribs and the salient points are of an integral structure and are made of POM materials; the integral structure is convenient for production; the POM material has good wear resistance and strong stability, and is suitable for various industries and different fields.

The known pedal assembly mainly comprises a support, a central shaft, a pedal arm and a pedal. In this specification: the shaft is a central shaft; the axle tube is the end of the pedal arm connected with the central shaft. The pedal arm is hinged with the support through a central shaft, the pedal is fixed on the pedal arm, and the pedal rotates around the central shaft through the pedal arm. The bush body of the utility model is assembled between the shaft and the shaft tube.

Claims
