Description

Technical Field

[0001] The utility model belongs to the field of clutch pressure plates, in particular to a clutch pressure plate capable of cooling and preventing cracking. Background Art

[0002] The automobile clutch pressure plate is one of the key components of the clutch system. It connects and disconnects the engine and transmission to achieve power transmission and clutch control, thereby affecting the starting of the vehicle.

[0003] During use, the clutch pressure plate will abut against the clutch to change gears, which will generate a lot of heat. The heat change over a long period of time can easily cause the pressure plate to crack, thus affecting its use. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides a clutch pressure plate capable of cooling and preventing cracking.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling and crack-proof clutch pressure plate, comprising a pressure plate, characterized in that: a connecting channel is opened inside the pressure plate, at least two grooves are opened on both sides of the pressure plate, and at least two movable components are arranged in the connecting channel;

[0006] The movable component includes a fixed block fixed in the connecting channel and a sliding block sliding in the connecting channel. The fixed block and the sliding block are connected together by a spring. The air convection generated by the back-and-forth movement of the sliding block accelerates the cooling of the pressure plate.

[0007] Optionally, the grooves are circumferentially distributed on both side end surfaces of the pressure plate, the positions of the grooves on both sides are alternately arranged, and the grooves are both connected to the connecting channel.

[0008] Optionally, the movable component is installed between two opposite grooves.

[0009] Optionally, a breathing hole is provided inside the fixed block, a gap exists between the sliding block and an inner wall of the connecting channel, and both side end surfaces of the sliding block are arc-shaped.

[0010] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Due to the setting of the movable group, the air between the fixed block and the sliding block can be sucked in and ejected from the breathing hole through the stretching and squeezing of the sliding block, forming a breathing effect, accelerating the flow of air inside the connecting channel, thereby achieving a rapid cooling effect, effectively reducing the temperature difference in the pressure plate, and thus greatly reducing the probability of cracking of the clutch pressure plate.

[0015] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0016] As shown in FIG1-2, a cooling and crack-proof clutch pressure plate includes a pressure plate 10, characterized in that: a connecting channel 11 is provided inside the pressure plate 10, at least two grooves 16 are provided on both sides of the pressure plate 10, the grooves 16 are circumferentially distributed on both side end surfaces of the pressure plate 10, the positions of the grooves 16 on both sides are alternately arranged, and the grooves 16 are connected to the connecting channel 11, at least two movable components are provided in the connecting channel 11, and the movable components are installed between two opposite grooves 16;

[0017] The movable component includes a fixed block 12 fixed in the connecting channel 11, and a sliding block 13 sliding in the connecting channel 11. The fixed block 12 and the sliding block 13 are connected together by a spring 14. The air convection generated by the back and forth movement of the sliding block 13 accelerates the cooling of the pressure plate 10. A breathing hole 15 is opened inside the fixed block 12. There is a gap between the sliding block 13 and the inner wall of the connecting channel 11, and the end faces of both sides of the sliding block 13 are arc-shaped.

[0018] When in use, the pressure plate 10 is pressed onto the clutch, and then when the vehicle is running and vibration occurs, the sliding block 13 will stretch the spring 14 to slide slightly in the connecting channel 11, and then be pulled to reset by the spring 14. In this process, the air between the fixed block 12 and the sliding block 13 can be sucked in and ejected from the breathing hole 15 through the stretching and squeezing of the sliding block 13, forming a breathing effect, accelerating the flow of air inside the connecting channel 11, thereby achieving a rapid cooling effect, effectively reducing the temperature difference in the pressure plate 10, and thus greatly reducing the probability of cracking of the clutch pressure plate.

[0019] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
