Description: TECHNICAL FIELD
[0001] The present subject matter relates generally to a brake assembly and a brake drum thereof. More particularly but not exclusively, the present subject matter relates to the brake drum for the brake assembly for decelerating a rotating member such as a wheel or rim or gears or other means for torque transmission or rotary motion of a vehicle. The brake assembly focuses on effective heat transfer and proper packaging of the components of the brake assembly without compromising on the functionality or integrity of the brake assembly.

BACKGROUND
[0002] Generally, the rural areas often have poor road conditions like dusty ways during dry summer seasons. These roads often get muddy and sludgy during the rainy season. The vehicles primarily used in rural areas, deploy drum brake systems which succumb to several problems. Firstly, the presence of dust, water, sludge, mud and other types of contaminants tends to enter inside the brake assembly leads to poor braking performance as the contaminants interfere with the smooth operation of the brake assembly. This reduces the efficiency of the brake system in slowing down or stopping the vehicle. This can also be a safety concern as it may lead to longer stopping distances or difficulties in controlling the vehicle. Secondly, the entry of contaminants can cause a squealing noise in the brake assembly. The accumulation of the contaminants further leads to their interaction or mixing up with the moving parts of the brake assembly. This generates unwanted sounds during braking which can be disruptive further affecting the overall driving experience and comfort of the user of the vehicle. Further, the presence of contaminants can negatively impact the durability and lifespan of the other components in the brake assembly and the wheel assemblies also to a certain extent. The abrasive nature of dust and mud particles can cause accelerated wear and tear on brake components, leading to premature deterioration. This can result in more frequent maintenance or replacement of brake parts, adding to the maintenance costs for the vehicle owners.
[0003] Further, a convective heat transfer refers to the process of transferring heat through the movement of a fluid, such as air. In the context of brake assembly, heat is generated during braking due to the friction between the brake pads or brake shoes and the rotor or brake drum. Heat generation gets worsened due abrasive nature of the contaminants. Efficient heat transfer is therefore, crucial to prevent the brake assembly from overheating, which can lead to a loss in braking performance or even brake fade and brake failure. Excessive heat can cause thermal stress and degradation of braking components, leading to premature wear and reduced lifespan of the brake assembly.
[0004] Therefore, there is a need to address the said problems by providing a brake drum for the brake assembly that enhances convective heat transfer and is designed, profiled and optimized in such a way that gets accommodated in the limited space of the wheel assembly of the vehicle. This will ensure a specific amount of space for all the components of the brake assembly to be installed and function properly within that limited space. Further, there is a need to reduce the number of contaminants reaching the brake system, thereby improving braking performance, noise reduction, and enhanced longevity of the other components of the brake assembly. Further, the above problem must be solved without changing the size of wheel rim or wheel assembly as that is usually standardized for the type of vehicle. The need is to achieve optimized profile for heat transfer and reduction in contaminants without altering the size of the wheel.

In order to address the above-mentioned problems, the present invention discloses a brake drum with a modified profile for a brake assembly. The modified brake drum has an annular rib design to prevent or minimize the entry of contaminants like dust and mud into the brake assembly as it creates a barrier and protective mechanism thereby improving braking performance, reducing noise while enhancing the longevity of the components of the brake assembly. The design and profile of the brake drum is optimized in line with the available space so that the braking system can be efficiently packaged without compromising the functionality or integrity of the other components of the brake assembly. The optimized design of the brake drum being provided with annular portion comprising annular rib members. The profile of the annular rib members is also optimized to fit within the confined space of the brake drum. The annular rib members effectively contribute to convective heat transfer and other desired benefits like braking performance and durability improvement without causing any interference or constraint issues within the wheel assembly. The design of the annular rib members for the brake drum has been done keeping in mind the most efficient and effective shape, dimensions, and positioning parameters that maximizes the benefits while still fitting the available space in the wheel assembly. Various factors like aerodynamics, thermal management, structural integrity, and compatibility with other components of the brake assembly have been considered to optimize the profile of the brake drum having the annular rib members. The weight and price of the brake assembly might increase due to disposition of the outer rib in the brake drum but this will also increase the overall life of the brake assembly.

[00031] The embodiments of the present invention will now be described in detail with reference to an embodiment in a brake assembly along with the accompanying drawings. However, the disclosed invention is not limited to the present embodiments.
[00032] The embodiments shown in Figure 1 illustrate a perspective view of a brake drum 100 having an internal surface 100I. Figure 2 illustrates a perspective view of the brake drum 100 having an external surface 100E in one embodiment of the invention. Figure 3 illustrates a top view of the brake drum 100 having the internal surface 100I in one embodiment of the invention. Figure 4 illustrates a side view of the brake drum 100 having the external surface 100E in one embodiment of the invention. Figure 1, Figure 2, Figure 3 and Figure 4 have been taken together for discussion. The brake drum 100 with a modified profile for a brake assembly 200 (as shown in Figure 8) is shown. The brake drum 100 comprises an external surface 100E and an internal surface 100I. The external surface 100E is configured to interface with the one or more rotating members 300 (as shown in Figure 7). The internal surface 100I is configured to face away from the one or more rotating member 300. The brake drum 100 comprises a mounting portion 100MP, a drum portion 100DP and an annular portion 100AP. The mounting portion 100MP is configured to fixedly connect the brake drum 100 to the one or more rotating member 300. The mounting portion 100MP of the brake drum 100 has a plurality of holes 100H that are configured to receive a plurality of fasteners to detachably attach the one or more rotating member 300 to the brake drum 100. A plurality of fins 100F is disposed along the external surface 100E of the brake drum 100 corresponding to the drum portion 100DP. The plurality of fins 100F projects outwardly from the drum portion 100DP. The plurality of fins 100F is configured to dissipate heat generated from the frictional engagement of the drum portion 100DP with the at least one brake shoe member 200BS (as shown in Figure 7). The plurality of fins 100F thus provides effective cooling to the brake assembly 200. The drum portion 100DP abuts the mounting portion 100MP while frictionally engaging with at least one brake shoe member 200BS (as shown in Figure 7) of the brake assembly 200 on a corresponding portion of the brake drum 100. The corresponding portion is the internal surface 100I of the brake drum 100. The annular portion 100AP is configured to laterally abut the drum potion 100DP. The annular portion 100AP dissipates heat generated from the drum portion 100DP by a frictional engagement of the drum portion 100DP with the at least one brake shoe member 200BS. The annular portion 100AP comprises two or more annular rib members 101, 102 that extend away from the drum portion 100DP.
[00033] The embodiments shown in Figure 5 illustrate a top view of the brake drum 100 having the external surface 100E showing axis AA in one embodiment of the invention. Figure 6 illustrates a cut-sectional view of the brake drum 100 cut across the axis AA in one embodiment of the invention. Figure 5 and Figure 6 have been taken together for discussion. In the brake drum 100 having the annular portion 100AP, the two or more annular rib members 101, 102 are disposed concentrically to each other. The two or more annular rib members 101, 102 circumferentially extend away from the drum portion 100DP within a pre-defined range of 14 to 18 millimetres. The two or more annular rib members 101, 102 have a predefined profile and a predefined thickness to act as a barrier for external contaminants from entering the brake assembly 200. As shown in the expanded view in Figure 6, the two or more annular rib members 101, 102 have been shown to have a thickness that runs consistently along the circumference of the brake drum 100. Instead of single annular rib, the two or more annular rib members 101, 102 with this predefined and consistent thickness ensures stability of the brake drum during rotation and balancing during frictional motion while braking. The predefined thickness has to be commensurate with the type of brake assembly and vehicular configuration. For example a heavier and large vehicle would obviously require thicker two or more annular rib members 101, 102. Further the predefined profile shown in Figure 6 is a U-shaped profile in the cut-section. This provides additional layer of safety from contaminants compared to a single annular rib. Further, the two or more annular rib members 101, 102 expose a larger surface area to the atmospheric air, promoting better airflow around the brake assembly 200. This increased surface area allows for enhanced convective heat transfer, facilitating the transfer of heat away from the brake drum 100. Effective heat dissipation helps in maintaining lower operating temperatures and ensures consistent braking performance and durability. By promoting better heat dissipation, the two or more annular rib members 101, 102 help in maintaining lower operating temperatures and reducing the potential for thermal damage to the brake assembly 200. This, in turn, improves the durability and longevity of the braking components as it reduces the frequency of maintenance or replacement of the braking components. The effective heat dissipation prevents the brake assembly 200 from reaching excessively high temperatures which ensures consistent braking performance by minimizing the likelihood of brake fading due to overheating. This improvement in heat dissipation leads to enhanced brake performance by preventing overheating, thermal stress, brake fading and eventually degradation. In a preferred embodiment, the predefined thickness of the two or more annular rib members 101, 102 is configured to create additional surface area in the brake assembly 200. However, optimizing the profile and design of the two or more annular rib members 101, 102 involves creating the most efficient and effective shape, dimensions, and positioning of the two or more annular rib members 101, 102 that can maximize the benefits while still fitting within the available space of the brake assembly 200. This optimization process may involve considering factors such as aerodynamics, thermal management, structural integrity, and compatibility with other components of the brake assembly 200. In the present embodiment, having considered the above factors and the size of the wheel assembly, the profile of two or more annular rib members 101, 102 are chosen as U-shaped when seen from the across a cross section AA. This ensures that the benefits of the two or more annular rib members 101, 102 can be realised without increasing the size of the wheel assembly and the concept can be easily applied to existing vehicles without changing their configuration or tyre or other wheel components. Moreover, the two or more annular rib members 101, 102 provides a projected surface over the backplate 200B (as shown in Figure 7 and Figure 8) that creates additional surface area in the brake drum 100. This increased surface area also promotes better airflow around the brake assembly 200 due to which the heat generated during braking is more effectively dispersed into the surrounding air.
[00034] The embodiments shown in Figure 7 illustrates a cross-sectional view of the brake assembly 200 of a rotating member 300. Figure 8 illustrates a perspective view of the brake assembly 200 in one embodiment of the invention. Figure 9a and Figure 9b illustrate a top and side view respectively of the brake assembly 200 in one embodiment of the invention. Figure 7, Figure 8, Figure 9a and Figure 9b have been taken together for discussion. The brake assembly 200 decelerates the one or more rotating member 300 (as shown in Figure 7) of a vehicle (not shown). The brake assembly 200 comprises a backplate 200B, at least one brake shoe member 200BS (as shown in Figure 7) and a brake drum 100 (as shown in Figure 1). The at least brake shoe member 200BS of the brake assembly 200 is forced to press against the inner surface of the brake drum 100. A friction is produced between the at least one brake shoe member 200BS and the brake drum 100 due to applied uniform pressure over the brake drum 100. This helps to reduce speed and to stop the vehicle. The backplate 200B is fixedly mounted to a portion of the vehicle behind the brake drum 100. The backplate 200B is a pressed plate made of metallic material. The backplate 200B is configured to provide support for the at least brake shoe member 200 and cylinder of the one or more rotating member 300. The backplate 200B is responsible for providing an outward pressure and decelerating force on the brake drum 100 for slowing the vehicle by providing required grip to stop the vehicle. This way, the backing plate 200B provides a stationery support in relation to the brake drum 100. The at least one brake shoe member 200BS is configured to be mounted on the backplate 200B. The at least one brake shoe member 200BS is configured to frictionally engage with the brake drum 100. The brake drum 100 is fixedly connected to the one or more rotating member 300. The brake drum 100 is configured to cover the at least one brake shoe member 200BS. The other features of the brake drum 100 have been discussed in detail in the preceding paragraph. The contents have been reiterated and not repeated for the sake of brevity.
[00035] Thus, the annular portion 100AP having the two or more annular rib members 101, 102 plays a crucial role in providing better sealing to prevent the entry of dust and mud into the brake drum 100. Since the brake drum 100 is the component that encloses the at least one brake shoe member 200BS and other internal brake components of the brake assembly 200, the external environmental contaminants like dust, mud and water can be particularly problematic as they can impair the braking performance, cause noise, and reduce the durability of the braking components. But by incorporating the above features, the present invention helped in creating a projected surface that acts as a barrier while reducing the likelihood of dust and mud entering the brake drum 100. This improved sealing helps to maintain a cleaner and more efficient braking system for the vehicle. Further, by providing an extra pair of the two or more annular rib members 101, 102 to the brake drum 100, the brake assembly 200 is designed to enhance convective heat transfer. The two or more annular rib members 101, 102 create additional surface area and thereby promotes better airflow around the brake shoe member 200BS and the brake drum 100 in the brake assembly 200. This increased surface area allows more contact between the heated brake components and the surrounding air, facilitating the transfer of heat away from the brake assembly 200. Furthermore, the present invention with improved sealing and better heat dissipation also contribute to the durability of braking components. With reduced exposure to foreign particles, the integrity of brake components is preserved due to minimized wear and tear. Effective heat dissipation prevents thermal stress and damage to the at least one brake shoe member 200BS and brake drum 100, thereby increasing their lifespan. Moreover, by controlled sealing and heat dissipation, the brake assembly 200 can also avoid brake noise. Proper sealing reduces the likelihood of vibration or rubbing of the braking components against each other which can cause unwanted noise like squealing when the brake is applied.
