Detailed Description
The objects, technical solutions and advantages of the present invention will become more apparent by the following detailed description of the present invention with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the invention. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present invention.
The specific embodiment is as follows:
referring to fig. 1-4, a spiral heat dissipation brake drum comprises a drum body 1, a reinforcing ring 14 is arranged on one side of the drum body 1, a heat dissipation sleeve 2 is arranged on the outer portion of the drum body 1, a heat conducting agent is arranged between the drum body 1 and the heat dissipation sleeve 2, a cavity 23 is formed in the heat dissipation sleeve 2, a phase-change energy storage material, preferably trisodium phosphate dodecahydrate, is arranged in the cavity 23, the phase-change temperature is between 70 ℃ and 80 ℃, and a plurality of spiral heat dissipation fins 22 are arranged on the outer portion of the heat dissipation sleeve 2, so that when the drum body 1 rotates forwards, the spiral heat dissipation fins 22 can generate air flow flowing from the surface of the heat dissipation sleeve 2. The heat dissipation sleeve 2 is made of a material with high strength, good heat conductivity and corrosion resistance, and can be made of titanium or stainless steel.
A plurality of raised strips 11 are arranged outside the drum body 1, and the extending direction of the raised strips 11 is parallel to the axis of the drum body 1; the inner wall of the heat dissipation sleeve 2 is provided with a plurality of grooves 21, and the raised strips 11 are positioned in the grooves 21. This structure can prevent the heat dissipation sleeve 2 from rotating relative to the drum body 1, and increases the heat conduction area between the heat dissipation sleeve and the drum body, and is more beneficial to the conduction of the heat of the latter to the former.
The heat conducting agent is heat conducting silicone grease, other materials such as total loss system oil can be selected, but the heat conducting silicone grease is best in high temperature resistance (up to 200 ℃) and is not easy to volatilize. The heat conducting agent fills the gap between the heat radiating sleeve 2 and the drum body 1, thereby eliminating air in the gap (the heat conductivity of the air is very low) and greatly enhancing the heat conducting capability between the two.
The drum body 1 is provided with a plurality of blocking blocks 3, and the blocking blocks 3 are positioned on one side of the heat dissipation sleeve 2 away from the reinforcing ring 14. The stopper 3 prevents the heat radiation jacket 2 from moving in the axial direction of the drum 1.
The blocking block 3 is provided with a through hole 31, the drum body 1 is provided with a plurality of threaded holes 12, and the blocking block 3 is fixed on the drum body 1 through bolts, specifically, the bolts penetrate through the through hole 31 and are in threaded connection with the threaded holes 12.
A blocking piece 32 is arranged on one side of the blocking piece 3, a rubber pad 33 is arranged on the outer side of the blocking piece 32, and the other side of the rubber pad 33 is in contact with the heat dissipation sleeve 2. The rubber pad 33 has elasticity, and when the heat dissipation case 2 expands due to a temperature rise, the rubber pad 33 may be compressed.
The rubber pad 33 may be made of fluororubber or silicone rubber, and has good heat resistance and weather resistance.
The reinforcing ring 14 is provided with a plurality of air guide holes 13, and the extending direction of the air guide holes 13 is inclined with the axis of the drum body 1, so that when the drum body 1 rotates forward (when the vehicle is driven to advance, the wheels rotate forward), air flow is generated in the air guide holes 13, and the air flow generated by the spiral cooling fins 22 flow in the same direction.
Working principle: when the brake is carried out, the heat generated by the drum body 1 is transferred to the heat dissipation sleeve 2, and when the drum body 1 exceeds a certain temperature (more than 70 ℃ if trisodium phosphate dodecahydrate is used), the phase change energy storage material in the heat dissipation sleeve 2 is subjected to phase change, so that a large amount of heat is absorbed, the temperature rise amplitude of the drum body 1 can be reduced, and the temperature rise of the drum body 1 is prevented from being too high. When the vehicle continues to run forwards after braking, the wheels drive the brake drum to rotate, and air flow generated by the spiral radiating fins 22 and the air guide holes 13 can promote the heat dissipation sleeve 2 to quickly cool and change phase, so that the heat absorption capacity of the heat dissipation sleeve is recovered.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and are in no way limiting of the invention. Accordingly, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present invention should be included in the scope of the present invention. Furthermore, the appended claims are intended to cover all such changes and modifications that fall within the scope and boundary of the appended claims, or equivalents of such scope and boundary.
