Description

Technical Field

[0001] This utility model relates to the field of automotive braking technology, and more specifically, to a heavy-duty vehicle braking mechanism. Background Technology

[0002] Hydraulic brake calipers are widely used in automotive braking systems. They primarily work by injecting hydraulic fluid into the oil chamber between the piston and the caliper body, causing the piston to push the brake pads against the brake disc to achieve braking. In traditional hydraulic brake calipers, the piston pushes the brake pads mounted on both sides of the brake disc to perform the braking operation. However, for heavier vehicles (armored vehicles, special vehicles, etc.), which often weigh several tons and have significant inertia, traditional hydraulic brake caliper systems result in very long braking distances, making it impossible to stop these vehicles. Furthermore, they suffer from poor heat dissipation during braking. Therefore, we propose a new heavy-duty vehicle braking mechanism. Utility Model Content

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figure 1 As shown, this utility model provides a heavy-duty vehicle braking mechanism, including: a brake caliper 1, two suspended brake discs 2, a coupling 3, an anti-detachment cover 4, a first brake pad 5, a second brake pad 6, and a third brake pad 7; the anti-detachment cover 4 is fixedly installed on the coupling 3 to form a mounting groove; the two suspended brake discs 2 are slidably installed in the mounting groove in a relative state; the brake caliper 1 is provided with a housing cavity for housing the two suspended brake discs 2; the first brake pad 5 and the second brake pad 6 are respectively slidably installed on both sides of the housing cavity; the third brake pad 7 is fixedly installed in the middle of the housing cavity; when the two suspended brake discs 2 are housed in the housing cavity, the two suspended brake discs 2 are placed in the gap between the first brake pad 5 and the second brake pad 6, and the third brake pad 7 is placed in the gap between the two suspended brake discs 2; the brake caliper 1 is provided with a drive module 8 for driving the first brake pad 5 and the second brake pad 6 to move relative to each other.

[0020] In this embodiment, as Figure 1-3 As shown, the anti-detachment cover 4 is made of aluminum. The two suspended brake discs 2 are slidably mounted on the coupling 3 through the anti-detachment cover 4 and the coupling 3. The coupling 3 is mounted on the car body via a swivel and is placed in the housing cavity of the caliper. In this embodiment, the first brake pad 5 and the second brake pad 6 are both single-sided friction brake pads, while the third brake pad 7 is a double-sided friction brake pad. During operation, when the brake pedal is pressed, the drive module 8 on the caliper works to synchronously push the first brake pad 5 and the second brake pad 6 to move relative to each other. During this process, the first brake pad is pushed by the drive module 8 towards the middle of the brake caliper 1. The first brake pad 5 moves a certain distance and contacts one of the suspended brake discs 2, while the second brake pad moves a certain distance and contacts the other suspended brake disc 2. Friction is generated, and braking effect begins at this point. Since the suspended brake disc 2 is in a suspended state, when the brake pedal is pressed deeper and the drive module 8 continues to push out, one suspended brake disc 2 is squeezed by the first brake pad 5 and moves towards the middle of the brake caliper 1 until it contacts the third brake pad 7, generating another friction force; the other suspended brake disc 2 is squeezed by the second brake pad 6 and moves towards the middle of the brake caliper 1 until it contacts the third brake pad 7, generating another friction force; this working principle greatly improves the braking effect; the overall structure is stable, easy to install, and can greatly improve the braking effect, realizing the braking operation of heavy vehicles. At the same time, the two suspended brake discs 2 are separated by the third brake pad 7, forming a natural heat dissipation channel, effectively improving the heat dissipation effect of the suspended brake disc 2.

[0021] Furthermore, the brake caliper 1 includes: a first caliper body 101 and a second caliper body 102; the first caliper body 101 and the second caliper body 102 are detachably connected by bolts; grooves are provided on the surfaces of the first caliper body 101 and the second caliper body 102 that abut against each other; the two grooves cooperate to form the receiving cavity; the first brake pad 5 is slidably installed in the groove of the first caliper body 101; the second brake pad 6 is slidably installed in the groove of the second caliper body 102.

[0022] In this embodiment, as Figure 1 As shown, the brake caliper 1 has a split structure. The first caliper body 101 and the second caliper body 102 are mainly assembled together by bolts, which ensures the structural strength while facilitating installation.

[0023] Further, the drive module 8 includes: a plurality of first drive pistons 81 and a plurality of second drive pistons 82; the first clamp body 101 is provided with a plurality of first piston chambers corresponding one-to-one with the plurality of first drive pistons 81; the plurality of first piston chambers are interconnected; the first clamp body 101 is also provided with a first oil supply line; the first oil supply line is interconnected with any of the first piston chambers; one end of each of the plurality of first drive pistons 81 is slidably mounted in the first piston chamber, and the other end of each of them can abut against the first brake pad 5; the second clamp body 102 is provided with a plurality of second piston chambers corresponding one-to-one with the plurality of second drive pistons 82; the plurality of second piston chambers are interconnected; the second clamp body 102 is also provided with a second oil supply line; the second oil supply line is interconnected with any of the second piston chambers; one end of each of the plurality of second drive pistons 82 is slidably mounted in the second piston chamber, and the other end of each of them can abut against the second brake pad 6.

[0024] In this embodiment, as Figure 3 As shown, there are three first driving pistons 81 and three second driving pistons 82, and each driving piston is provided with a dust cover. In other embodiments, the number of pistons can be increased or decreased according to the actual application. During operation, the three first driving pistons 81 and the three second driving pistons 82 work synchronously to push the first brake pad 5 and the second brake pad 6 to move synchronously in opposite directions to achieve braking operation.

[0025] Furthermore, the top of the opposing surfaces of the first clamp body 101 and the second clamp body 102 are each provided with a slot; the two slots cooperate to form a bayonet; the bayonet communicates with the receiving cavity; a support rod 9 is mounted on the bayonet; a guide rod 10 is respectively provided in the bayonet and on both sides of the support rod 9; the assembly end of the first brake pad 5 is fixedly connected to the middle end of the guide rod 10; the assembly end of the second brake pad 6 is slidably connected to the other end of the guide rod 10; the assembly end of the third brake pad 7 is slidably connected to the middle end of the guide rod 10; a spring plate 13 is installed on the support rod 9; the spring plate 13 abuts against the first brake pad 5, the second brake pad 6 and the third brake pad 7 respectively.

[0026] In this embodiment, as Figure 1-3 As shown, the first brake pad 5 and the second brake pad 6 are slidably connected to each other on both sides of the housing cavity of the brake caliper 1 through two guide rods 10; while the third brake pad 7 is fixedly connected to the middle ends of the two guide rods 10 respectively, so that it can be installed in the middle of the housing cavity, so that it can be placed in the gap between the two suspended brake discs 2 during assembly.

[0027] Furthermore, a first anti-collision plate 11 adapted to the first brake pad 5 is provided in the groove of the first clamp body 101; a second anti-collision plate 12 adapted to the second brake pad 6 is provided in the groove of the second clamp body 102; the specific provision of anti-collision plates can reduce the generation of noise during braking.
