Description

Technical Field

[0001] The present application relates to the field of brake pads, and in particular to a high-temperature resistant brake pad for carbon-ceramic discs. Background Art

[0002] Carbon ceramic disc is a high-performance brake disc material with low mass, high wear resistance and excellent heat dissipation performance. For carbon ceramic discs used with high-temperature resistant brake pads, a composite material of carbon ceramic matrix and high-temperature wear-resistant material is usually used. During the use of carbon ceramic discs and brake pads, they often face a high-intensity braking environment.

[0003] Existing brake pads mostly use air heat dissipation to dissipate heat after braking. Due to the small overall gap between the carbon-ceramic disc body and the brake pad body, it is easy for the airflow to not pass through the connection between the carbon-ceramic disc body and the brake pad body to dissipate heat well during vehicle driving. As a result, the overall braking effect of the brake pad is poor, and after long-term use of the brakes, the braking effect is likely to decrease.

[0004] Therefore, a carbon ceramic disc high temperature resistant brake pad is needed to assist in solving this problem. Utility Model Content

[0030] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] This specific embodiment is a high temperature resistant brake pad for carbon ceramic disc, such as Figure 1 、 Figure 2 and Figure 3 As shown, the carbon-ceramic disc is a high-temperature-resistant brake pad carbon-ceramic disc body 1. A plurality of heat dissipation holes 2 are provided in a circular array on the outer edge of the carbon-ceramic disc body 1. A mounting seat 3 is protruding from the center of the outer edge of the carbon-ceramic disc body 1. The heat dissipation holes 2 can significantly accelerate the dissipation of heat within the carbon-ceramic disc body 1. The heat dissipation holes 2 can serve as a heat conduction channel to transfer heat more quickly to other parts of the accelerating carbon-ceramic disc body 1 or the external environment, thereby reducing the overall temperature of the accelerating carbon-ceramic disc body 1.

[0032] The outer side of the carbon ceramic disc body 1 is clamped and mounted with a brake pad assembly 4 for auxiliary braking. The brake pad assembly 4 includes a mounting shell 5. Two mounting shells 5 are provided. The two ends of the two mounting shells 5 are connected and fixed by fixing bolts 8. A clamping cavity 51 for the carbon ceramic disc body 1 to be clamped and fixed is reserved between the two mounting shells 5. A mounting plate 9 is installed on the inner side of the clamping cavity 51. A brake pad body 10 is installed on the mounting plate 9. The brake pad body 10 is an arc-shaped plate structure. A slag discharge port 101 is symmetrically opened on the brake pad body 10. The slag discharge port 101 can be used to remove smaller impurities during braking. In order to effectively discharge the material, an oil pump shell 6 for assisting the brake pad body 10 to squeeze the brake is installed on the outer side of the mounting shell 5, and an oil pump 7 pushed by the auxiliary brake pad body 10 is installed on the oil pump shell 6. A heat dissipation component 11 for auxiliary heat dissipation is installed on the outer side of the mounting shell 5. The heat dissipation component 11 includes a guide shell 12 fixed on the outer side of the mounting shell 5, a guide cavity groove 121 is provided on the guide shell 12, and a guide cavity is provided at the corresponding guide cavity groove 121 on the mounting shell 5. A deflector plate 13 is obliquely fixed at the guide cavity, and a number of deflector plates 13 are provided, and a number of deflector plates 13 are provided at the guide cavity.

[0033] By providing the guide shells 12 that expand outward on both sides of the mounting shell 5, the airflow can be intercepted during the driving of the vehicle through the guide shells 12 that expand on both sides, and the brake pad body 10 is assisted in blowing air along the guide cavity groove 121 on the guide shell 12 and the inverted flow plate 13 at the guide cavity, so that more airflow is blown to the brake pad body 10 and the air flow at the brake pad body 10 is accelerated, thereby assisting in accelerating the heat dissipation of the brake pad body 10, ensuring a better braking effect when the brakes are used for a long time, and avoiding the problem of poor overall air heat dissipation effect due to the small gap between the carbon ceramic disc body 1 and the brake pad body 10 as much as possible.

[0034] Reference Figure 2 and Figure 4 As shown, both ends of the brake pad body 10 are protrudingly provided with protruding seats, and fixing holes are drilled on the mounting plate 9. The protruding seats and the fixing holes are connected and fixed by a fixing assembly 14. The fixing assembly 14 includes a fixing column 15, and an expansion rod 16 is symmetrically hingedly installed on the fixing column 15. A clamping groove 161 is provided on the outer side of the expansion rod 16. An ejection cavity is provided at the center of the fixing column 15, and a screw rod 19 is rotatably provided at the ejection cavity. A ring 18 is sleeved on the screw rod 19, and a support rod 17 is obliquely hingedly installed between the ring 18 and the inner side edge of the expansion rod 16. An embedded disk 191 is rotatably embedded on the fixing column 15, and one end of the screw rod 19 is fixed in the embedded disk 191.

[0035] By setting the fixing component 14 at the connection position between the mounting plate 9 and the brake pad body 10, the embedded disk 191 is reversed, and the embedded disk 191 drives the screw rod 19 to rotate, and the threads of the ring 18 and the screw rod 19 are engaged, so that the ring 18 moves inward as a whole, and then the support rod 17 pulls the deployment rod 16 to be retracted as a whole. At this time, the fixing column 15 can be pulled out from the fixed air to realize the overall disassembly of the fixing column 15, which can facilitate the quick disassembly and replacement of the brake pad body 10 during work.

[0036] Working principle:

[0037] When braking is required, the oil pump 7 at the oil pump housing 6 is started. During the process of the oil pump 7 supplying oil, the mounting plate 9 is pushed, and then the brake pad body 10 is pushed. During the process of the brake pad body 10 being pushed, the brake pad body 10 is clamped on both sides of the carbon ceramic disc body 1, thereby performing auxiliary planning processing.

[0038] During driving, the airflow can be intercepted by the guide shells 12 unfolded on both sides during the driving of the vehicle, and auxiliary blowing treatment is performed on the brake pad body 10 along the guide cavity groove 121 on the guide shell 12 and the backflow plate 13 at the guide cavity, so that more airflow is blown to the brake pad body 10 and the air flow at the brake pad body 10 is accelerated, thereby assisting in accelerating the heat dissipation of the brake pad body 10, ensuring better braking effect when the brakes are used for a long time.

[0039] When disassembling the brake pad body 10, the embedded disk 191 is reversed, and the embedded disk 191 drives the screw rod 19 to rotate. The threads of the ring 18 and the screw rod 19 are engaged, so that the ring 18 moves inward as a whole, and then the support rod 17 pulls the deployment rod 16 back as a whole. At this time, the fixing column 15 can be pulled out from the fixed air to realize the overall disassembly of the fixing column 15.
