Description
Technical Field
The utility model relates to a push rod structure for automobile clutch especially relates to a novel high strength combined material push rod assembly.
Background
In recent years, with the continuous development of the automobile industry and the continuous rise of the international oil price, the requirements of consumers on automobile products are gradually changed from the previous practicability to the requirements on energy conservation, environmental protection and comfort, and the lightweight automobile is realized, so that the power performance is improved, the fuel consumption is reduced, the exhaust pollution is reduced, and the requirements are the targets of common efforts of various major host factories.
The innovation of chemical industry enriches the types of polymer composite materials, improves the performance of the composite materials, has mechanical properties not inferior to those of metal materials in some engineering polymer composite materials, and has become a technical progress by adopting the engineering polymer composite materials to replace various metal materials, so that favorable conditions are provided for the light weight of automobiles, and the consumption of plastic of each automobile becomes one of the marks for measuring the technical level of automobile production.
Under the big background, a novel high-strength composite material push rod assembly is developed, the whole push rod assembly is formed by injection molding of a composite material, and the cost is greatly reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists among the background art, the utility model aims to solve the technical problem that a novel high strength combined material push rod assembly is just provided, adopt the integrative moulding plastics of combined material to form to the intensity problem of push rod assembly has been solved through the innovative design of novel high strength combined material push rod assembly oval structure, has improved the adaptability of push rod assembly simultaneously by a wide margin, realizes thoroughly replacing the possibility of metal push rod assembly, and this has created better condition for the main cylinder lightweight.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the push rod assembly is connected with the clutch master cylinder, one end of the push rod assembly is arranged into a U-shaped frame structure, the U-shaped frame structure is connected to the clutch pedal, the other end of the push rod assembly is used as a push rod portion, the push rod portion is connected to a piston in the clutch master cylinder, the cross section of the push rod portion is an oval cross section to form a rod portion of an oval column, and the head of the push rod portion is spherical.
The wide edge of the oval section is along the direction of a large swing angle of the clutch master cylinder.
Under the prerequisite that equal material does not sacrifice the pivot angle like this, make the push rod assembly can bear bigger footboard power through the cross-section that increases the pivot angle direction, and the condition that the push rod assembly fracture can not appear. Because the intensity of the push rod assembly is greatly improved, the composite material push rod assembly has wider adaptability, and the cost is greatly reduced compared with the original metal push rod assembly.
The push rod assembly is specifically formed by integrally injection molding of a polymer composite material.
The polymer composite material is specifically PA66 GF 35.
The utility model has the advantages that:
the utility model discloses a direct an organic whole of combined material is moulded plastics and is formed, has saved metal material, and manufacturing cost descends by a wide margin, the great push rod assembly of adaptable length simultaneously, and adaptability is stronger.
The utility model provides a not enough, the cracked technical problem takes place after sale of push rod assembly intensity, and solved and only be suitable for shortcomings such as shorter push rod assembly by the length restriction.
Drawings
FIG. 1 is a side view of a tappet assembly;
FIG. 2 is a cross-sectional view of a putter shaft portion of the putter assembly;
FIG. 3 is a top view of the tappet assembly.
In the figure: the push rod assembly comprises a push rod assembly 1, a push rod part 2 and an oval section 3.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1 and 3, the push rod assembly 1 is a push rod assembly connected to a clutch master cylinder, and is characterized in that: one end of the push rod assembly 1 is arranged to be in a U-shaped frame structure, the U-shaped frame structure is connected to the clutch pedal, the other end of the push rod assembly 1 serves as a push rod part 2, the push rod part 2 is connected to a piston in a clutch master cylinder, the cross section of the push rod part 2 is an elliptical cross section 3 to form a rod part of an elliptical column, the head of the push rod part 2 is spherical, as shown in fig. 2, and the wide edge of the elliptical cross section 3 is along the large swing angle direction of the clutch master cylinder.
Through above novel high strength combined material push rod assembly innovative design, be connected the back with the footboard, the oval broadside in pole portion of push rod assembly arranges from top to bottom, and is corresponding with the biggest direction of push rod assembly pivot angle, the structural innovation design and the arrangement of push rod assembly for its intensity promotes by a wide margin, makes push rod assembly intensity promote by a wide margin, promotes more than 2 times. Meanwhile, the push rod assembly is suitable for push rod assemblies under longer working conditions. But the requirement of the pedal on the swing angle of the main cylinder is not reduced, and the push rod assembly with larger length can also be adapted.
Meanwhile, the push rod assembly can be integrally formed by injection molding of composite materials, so that metal materials are saved, and the cost is greatly reduced.
As shown in fig. 1, the high-strength composite material push rod assembly 1 of the present invention has a rod portion 2, and the rod portion 2 is designed to have an elliptical cross section 3. Through above novel high strength combined material push rod assembly innovative design for push rod assembly intensity promotes by a wide margin, promotes more than 2 times, can be applicable to the push rod assembly of longer operating mode simultaneously. Because the push rod assembly can be integrally formed by injection molding of composite materials, metal materials are saved, and the cost is greatly reduced.
