[0016] The utility model is described in detail below in combination with the drawings and examples.

[0017] Example:

[0018] The clutch pressure disc for engineering vehicle, as shown in Figure 1 And Figure 2 Disclosed, including disc body, disc body includes installation disc 1 and replacement disc 2 that are coaxially arranged, installation disc 1 is used to install diaphragm spring, both sides of replacement disc 2 can be detachably connected on installation disc 1, the outer diameter of replacement disc 2 is equal to the outer diameter of installation disc 1, the outer peripheral wall of installation disc 1 is welded with three fixed lug board one 3, the outer peripheral wall of replacement disc 2 is welded with three fixed lug board two 4 that are correspondingly arranged with fixed lug board one 3, bolt 5 is jointly screwed in fixed lug board one 3 and fixed lug board two 4, threaded hole is set up on fixed lug board one 3 and fixed lug board two 4, the thickness of fixed lug board two 4 is less than the thickness of replacement disc 2, the distance of fixed lug board two 4 to both sides of replacement disc 2 is equal, one side of installation disc 1 is welded with three limit posts 6, three limit holes 7 for the clamping of limit post 6 are set up on replacement disc 2, the length of limit post 6 is less than the depth of limit hole 7, a plurality of heat dissipation holes 8 are set up on replacement disc 2, installation disc 1 and replacement disc 2 all adopt grey cast iron material to make.

[0019] When the replacement disc 2 is installed on one side of the mounting disc 1, the limiting column 6 is embedded in the limiting hole 7, at this time, the fixed ear plate one 3 on the mounting disc 1 and the fixed ear plate two 4 on the replacement disc 2 are arranged correspondingly, which has the effect of pre-fixing, then the bolt 5 is screwed into the threaded hole of the fixed ear plate one 3 and the fixed ear plate two 4, which improves the stability of the replacement disc 2 on the mounting disc 1, then in the running process of the clutch, the friction plate only contacts one side of the replacement disc 2, because the length of the limiting column 6 is less than the depth of the limiting hole 7, the distance from the fixed ear plate two 4 to the two sides of the replacement disc 2 is equal, so that in the process of mutual contact and friction between the replacement disc 2 and the friction plate, the end surface of the limiting column 6, the fixed ear plate two 4 and the bolt 5 are not in contact with the friction plate, which avoids the abrasion of the limiting column 6 and the bolt 5, when one side of the replacement disc 2 is abraded, the bolt 5 is first disassembled to be separated from the fixed ear plate one 3 and the fixed ear plate two 4, then the replacement disc 2 is disassembled, at this time, the limiting column 6 gradually separates from the limiting hole 7, then the disassembled replacement disc 2 is turned over, the side of the replacement disc 2 which has been abraded is towards the mounting disc 1, the other side of the replacement disc 2 which has not been abraded is towards the friction plate, then the replacement disc 2 is installed on the mounting disc 1, at this time, the limiting column 6 gradually embeds in the limiting hole 7, until the side of the replacement disc 2 which has been abraded contacts the mounting disc 1, then the bolt 5 is screwed into the fixed ear plate one 3 and the fixed ear plate two 4, the other side of the replacement disc 2 can be used to contact the friction plate, until both sides of the replacement disc 2 are abraded, then the replacement disc 2 which has been abraded on both sides is disassembled and replaced, the mounting disc 1 can continue to be used without replacing the whole disc, in the process of mutual contact and abrasion between the replacement disc 2 and the friction plate, heat is generated between them, because of the existence of the several heat dissipation holes 8, the heat generated when the replacement disc 2 and the friction plate rub against each other is dissipated through the heat dissipation holes 8, which improves the heat dissipation efficiency of the replacement disc 2, so that the heat in the replacement disc 2 can be dissipated in time, avoiding the deformation of the replacement disc 2 due to the high internal heat, thereby improving the service life, the gray cast iron has good wear resistance, which reduces the abrasion of the replacement disc 2 in the process of mutual friction with the friction plate.
