Description

Quick connecting structure of clutch master cylinder push rod assembly and pedal arm

Technical Field

The utility model relates to a novel clutch master cylinder push rod assembly and pedal arm quick connect structure.

Background

With the gradual maturity of automobile design, the assembly between each part of automobile develops towards the direction of lighter, more convenient, more swift, take the connection of clutch master cylinder push rod assembly and pedal arm as an example, traditional assembly method adopts the round pin axle to be connected U type push rod fork and pedal arm, and then uses the split pin to prevent taking off fixedly, and this method assembly process is more loaded down with trivial details, and in the space narrow and small or not in the scope of sight, the dismantlement of split pin is very difficult, and after-sale maintenance is very troublesome.

Disclosure of Invention

This with novel a novel clutch master cylinder push rod assembly and pedal arm quick connect structure that provides can realize rapid Assembly, even if not in sight range, also can easily accomplish, improved operating efficiency greatly, reduced operative employee intensity of labour.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the utility model comprises a push rod assembly and a pedal arm, wherein the pedal arm is connected with the push rod assembly through a pedal pin shaft, an annular groove is arranged on the outer peripheral surface of the pedal pin shaft along the circumferential direction, and the upper step surface of the annular groove is obliquely transited to the outer peripheral surface of the pin shaft through a chamfer structure; at least two reverse buckles are uniformly arranged in the mounting hole of the push rod assembly along the circumferential direction, the lower ends of the reverse buckles obliquely extend out of the mounting hole towards the center of the mounting hole, oblique angle convex blocks are processed at the lower ends of the reverse buckles, and the pedal arms are embedded in the annular grooves through the oblique angle convex blocks to be connected and fixed with the push rod assembly.

The oblique angle lug all bulge towards the center of mounting hole, the axial positioning of footboard arm is realized to oblique angle lug and annular groove cooperation installation.

The annular groove is provided with the following positions which need to be met: the axial distance between the annular groove and the pedal arm is larger than the thickness of the mounting hole of the push rod assembly.

The reverse buckle is made of high molecular polymer materials and is molded through injection molding.

The utility model has the advantages that: the quick installation function between push rod assembly and pedal arm has been realized, compares with traditional push rod and footboard connection structure, even if not in sight range, also can easily accomplish the assembly, has improved operating efficiency greatly.

Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1, if the push rod assembly of the clutch master cylinder is to be quickly connected with the pedal arm, that is, the push rod assembly is to be quickly connected with the pin shaft on the pedal arm, as shown in fig. 1, the utility model comprises a part push rod assembly 1 and a pedal arm 2; two back-off buttons 3 are arranged in the mounting holes of the push rod assembly 1, and transition oblique angles are arranged on two sides of the back-off buttons 3; an annular groove 4 is arranged on the pedal arm pin shaft, and oblique angles are arranged on two sides of the annular groove 4, as shown in figure 3. The distance between the annular groove 4 and the pedal arm 2 needs to be larger than the thickness of a mounting hole of the push rod assembly, and the mounting can be ensured to be in place. The size of the reverse buckle 3 and the size of the annular groove 4 are matched, so that the reverse buckle 3 is stably embedded in the annular groove 4 and does not move. The design of the bevel angles of the reverse buckle 3 and the annular groove 4 makes the installation more labor-saving, and the reverse buckle extrusion deformation is not easy to damage during the installation. The quick connection structure is realized by the back-off structure on the push rod assembly, and is matched with the annular groove 4 on the pedal arm for use, so that the quick connection of the push rod assembly and the pedal arm is realized.

In the specific implementation, the reverse buckle 3 of the push rod assembly 1 is made of high molecular polymer. The high molecular polymer has higher strength and good injection molding performance, and meets the use conditions of the push rod assembly of the clutch master cylinder.

The working process of the utility model is as follows:

as shown in fig. 2, when the push rod assembly 1 is connected with the pedal arm 2, the pedal pin shaft is inserted into the mounting hole of the push rod assembly 1, and the pin shaft is extruded through the mounting hole reverse buckle 3 by the insertion force and the oblique angle structure of the two parts, so that the reverse buckle 3 on the mounting hole is embedded into the annular groove 4 of the pedal pin shaft, and the pedal arm 2 is quickly connected and fixed with the push rod assembly 1 of the clutch master cylinder.

The utility model discloses quick connection structure can realize the quick installation of push rod assembly and pedal arm, even if not in sight range, also can easily accomplish, has improved operating efficiency greatly, has reduced operative employee intensity of labour.
