Description

Technical Field

[0001] This utility model relates to the technical field of dry friction clutch pressure plate assembly, specifically a diaphragm spring travel blocking and limiting component for a clutch. Background Technology

[0002] A clutch is a device in a mechanical transmission system used to connect or separate two rotating parts. It allows for the transmission or interruption of power and the matching of speeds between different parts by controlling the engagement and disengagement of the clutch during machine operation. It has a simple structure, reliable operation, and can engage and disengage smoothly. It is widely used in vehicles such as automobiles and motorcycles. As the service life of the clutch gradually increases, excessive pedal travel causes friction between the clutch diaphragm spring and the diaphragm spring's cylindrical hole, thus affecting the service life of the diaphragm spring. Therefore, a clutch diaphragm spring travel blocking and limiting component is proposed to solve the above-mentioned problems. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a diaphragm spring stroke blocking and limiting component for a clutch, including a pressure plate with a protrusion. A pressure cover is provided above the pressure plate, and a through bolt is provided on the pressure cover. A threaded hole adapted to the bolt is provided on the pressure plate. A through diaphragm rivet is provided on the pressure cover, and a diaphragm rivet has a diaphragm oblong hole. A diaphragm spring is provided in the diaphragm oblong hole, and one end of the diaphragm spring abuts against the protrusion. A limiting component for changing the travel of the diaphragm spring is provided at one end of the diaphragm rivet.

[0004] Furthermore, the limiting component includes a limiting baffle, which is fixedly installed on the diaphragm rivet and located inside the diaphragm's oval hole. The limiting baffle and the pressure cover side surface are both provided with limiting shafts, and the diaphragm spring is located between the two limiting shafts.

[0005] Furthermore, the limiting baffle is made of one of the following materials: high manganese steel plate, wear-resistant ferrochrome steel plate, low alloy steel plate, nickel metal material, or laser additive manufacturing single crystal nickel-based high temperature alloy.

[0006] The beneficial effects of this utility model are as follows: By setting a limiting member at one end of the diaphragm rivet, this utility model can accurately control the active stroke of the diaphragm spring, preventing unnecessary friction between the diaphragm and the diaphragm's oval hole due to excessive pedal stroke, thereby protecting the diaphragm spring from wear and extending its service life. The limiting member and the diaphragm rivet are integrated into a compact structure, without adding extra space burden. At the same time, the matching design of the limiting member with the pressure cap, diaphragm rivet and other components is reasonable, which facilitates installation and maintenance and reduces the cost of use.

[0009] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0010] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0011] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0012] In the embodiments, by Figure 1Provided is a diaphragm spring travel blocking and limiting component for a clutch, characterized in that: it includes a pressure plate 1, on which a protrusion 2 is provided; a pressure cover 3 is provided above the pressure plate 1; a through bolt is provided on the pressure cover 3; a threaded hole adapted to the bolt is provided on the pressure plate 1; a through diaphragm rivet 4 is provided on the pressure cover 3; a diaphragm oblong hole 5 is provided on the diaphragm rivet 4; a diaphragm spring 6 is provided in the oblong hole 5; and one end of the diaphragm spring 6 abuts against the protrusion 2. One end of the diaphragm rivet 4 is provided with a limiting member 7 for changing the travel of the diaphragm spring 6. When the clutch pedal is pressed, the diaphragm spring 6 will be subjected to pressure and displacement. The end that contacts the protrusion 2 will tilt upwards, while the other end will rotate downwards until it contacts the limiting member 7 and generates resistance, preventing the diaphragm spring 6 from continuing to move. Therefore, even if the pedal travel is too large, the diaphragm spring 6 will not generate unnecessary friction with the diaphragm oblong hole 5, thereby protecting the diaphragm spring 6 from wear and extending its service life.

[0013] Reference Figure 1 The limiting component 7 includes a limiting baffle 71, which is fixedly installed on the diaphragm rivet 4 and located in the diaphragm oval hole 5. The limiting baffle 71 and the pressure cover 3 are both provided with limiting shafts 72, and the diaphragm spring 6 is located between the two limiting shafts 72.

[0014] With the above structural design, the limiting member 7 effectively restricts the travel of the diaphragm spring 6 through the cooperation of the limiting baffle 71 and the limiting shaft 72.

[0015] Reference Figure 1 The limiting baffle 71 is made of one of the following materials: high manganese steel plate, wear-resistant ferrochrome steel plate, low alloy steel plate, nickel metal material or laser additive manufacturing single crystal nickel-based high temperature alloy.

[0016] Through the above structural design, the limiting baffle 71, with its high strength, high wear resistance material properties and precise structural design, effectively limits and protects the travel of the diaphragm spring 6, thereby extending the service life of the clutch and improving its reliability.

[0017] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
