[0023] The first embodiment of the present utility model is as follows:

[0024] A new type of brake caliper includes a brake pan 11, a brake disc 3 and the brake pan 11 are connected by bolts, the brake disc 3 is fixedly connected to the axle 4 and is relatively fixed, a brake disc 10 is installed at the end of the wheel hub, and the brake disc 10 is located between the fixed brake pad 7 and the movable brake pad 6. When the car is driving, the wheel hub and the brake disc 10 also rotate synchronously. When braking, the brake disc 10 needs to be clamped by the fixed brake pad 7 and the movable brake pad 6 to generate braking force, so that the brake disc 10 stops rotating and the wheel hub also stops rotating.

[0025] Two sets of brake assemblies are symmetrically installed on the brake pan 11. The angle between the two sets of brake assemblies is 180 degrees, which can evenly distribute the braking force at both ends of the brake disc 10 instead of one end of the transmission brake device, thereby ensuring a more balanced distribution of the braking force. On the one hand, it improves the balance of the brake and ensures that the degree of wear of the brake pads is the same. On the other hand, it increases the braking force. Most importantly, it makes the brake disc 10 more evenly stressed during braking, which not only improves the braking effect but also protects the brake disc 10 from damage.

[0026] The brake assembly includes an oil pump 8 fixedly mounted on the brake pan 11, and two oil pumps 8 are connected to branch oil pipes, and the two branch oil pipes are connected and connected to the main oil pipe 9. A piston rod is retractably mounted on the oil pump 8, and the other end of the piston rod is connected to the auxiliary caliper 2. A brake arm 1 is mounted on the other side of the brake pan 11, and the other end of the brake arm 1 is fixedly connected to the main caliper 5. The positions of the main caliper 5 and the auxiliary caliper 2 correspond to each other. A fixed brake pad 7 is detachably mounted on the inner side surface of the main caliper 5, and a movable brake pad 6 is detachably mounted on the inner side surface of the auxiliary caliper 2. The orthographic projections of the movable brake pad 6 and the fixed brake pad 7 overlap with each other.

[0027] During braking, the brake hydraulic oil enters the branch oil pipe from the main oil pipe 9 and enters the two oil pumps 8 in equal amounts, pushing the piston rod outward by the same distance, pushing the secondary caliper 2 toward the main caliper 5, and the two movable brake pads 6 contact the brake disc 10 at the same time, thereby generating the same braking force.

[0028] The length of the movable brake pad 6 and the fixed brake pad 7 is 430 mm. At the same time, the overall structure has four brake pads, which are evenly arranged in symmetrical positions on the brake disc 10, which can generate greater braking force. At the same time, the braking force is balanced and the braking force is stronger.

[0029] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.
