Description

Technical Field

[0001] The utility model relates to the technical field of brake equipment, in particular to a brake caliper assembly and a brake. Background Art

[0002] Common braking systems on two-wheeled vehicles include disc brakes and drum brakes. Disc brakes are widely accepted by consumers due to their excellent braking performance. However, with increasing demand, disc brakes on two-wheeled vehicles have begun to experience problems such as nodding and side slipping during braking.

[0039] This embodiment provides a brake caliper assembly. Figures 1 to 2 As shown, the brake caliper assembly includes a housing 1, a front brake pad assembly 21, a rear brake pad assembly 22, a piston assembly 3, a front oil pipe 41, and a rear oil pipe 42. The front brake pad assembly 21 includes two oppositely disposed front brake pads 211. The rear brake pad assembly 22 includes two oppositely disposed rear brake pads 221. The piston assembly 3 includes a front piston 31 connected in a one-to-one correspondence with the front brake pads 211, and a rear piston 32 connected in a one-to-one correspondence with the rear brake pads 221. Both the front pistons 31 and the rear pistons 32 are reciprocatingly disposed within the housing 1. The front oil pipe 41 is disposed on the housing 1, and the rear oil pipe 42 is disposed on the housing 1. The flow of brake oil into the front oil pipe 41 can drive the two front pistons 31 toward each other, thereby bringing the two front brake pads 211 toward each other. The flow of brake oil into the rear oil pipe 42 can drive the two rear pistons 32 toward each other, thereby bringing the two rear brake pads 221 toward each other.

[0040] In this embodiment, when the brake caliper assembly is applied to a two-wheeled vehicle, the front brake pad group 21 and the rear brake pad group 22 can be controlled respectively by the left and right brake handles. Specifically, taking the left brake handle controlling the front brake pad group 21 and the right brake handle controlling the rear brake pad group 22 as an example, when only the front brake pad group 21 is controlled, the driver holds the left brake handle, and the front oil pipe 41 is fed with brake oil to drive the two front pistons 31 closer to each other, so that the two front brake pads 211 respectively provided on the two front pistons 31 are closer to each other, thereby braking the brake disc of the brake; when only the rear brake pad group 22 is controlled, the driver holds the right brake handle, and the rear oil pipe 42 is fed with brake oil to drive the two rear pistons 32 closer to each other. This approach causes the two rear brake pads 221, respectively provided on the two rear pistons 32, to approach each other, thereby braking the brake disc. When the front and rear brake pad groups are controlled simultaneously, the driver simultaneously grasps the left and right brake handles, and brake oil is respectively introduced into the front oil pipe 41 and the rear oil pipe 42, which simultaneously drives the two front pistons 31 and the two rear pistons 32 toward each other, causing the two front brake pads 211 and the two rear brake pads 221 to approach each other and brake the brake disc simultaneously, thereby achieving coordinated control. The brake caliper assembly is provided with two independent front brake pad groups 21 and rear brake pad groups 22. The front brake pad groups 21 and rear brake pad groups 22 can operate independently or in a coordinated manner. The independent and coordinated operations do not interfere with each other, which can further improve the uniformity of braking force distribution when the driver brakes with both hands.

[0041] Specifically in this embodiment, the housing 1 is provided with a first inner cavity 101 and a second inner cavity 102. The first inner cavity 101 is provided in a one-to-one correspondence with the front piston 31, and the front piston 31 reciprocates within the first inner cavity 101. The second inner cavity 102 is provided in a one-to-one correspondence with the rear piston 32, and the rear piston 32 reciprocates within the second inner cavity 102. The two first inner cavities 101 are connected, and the two second inner cavities 102 are connected. The front oil pipe 41 is connected to one of the first inner cavities 101, and the rear oil pipe 42 is connected to one of the second inner cavities 102. Specifically, the front piston 31 reciprocates within the first inner cavity 101 to drive the front brake pad 211 to move, and the rear piston 32 reciprocates within the second inner cavity 102 to drive the rear brake pad 221 to move. When brake oil is introduced into the front oil pipe 41, the brake oil first enters into a first inner cavity 101, and then enters into another first inner cavity 101 connected thereto through the first inner cavity 101, pushing the two front pistons 31 to move toward each other; when brake oil is introduced into the rear oil pipe 42, the brake oil first enters into a second inner cavity 102, and then enters into another second inner cavity 102 connected thereto through the second inner cavity 102, pushing the two rear pistons 32 to move toward each other.

[0042] Specifically in this embodiment, a first flow channel 13 and a second flow channel 14 are defined within the housing 1. The first flow channel 13 connects the two first inner cavities 101, and the second flow channel 14 connects the two second inner cavities 102. When brake oil is introduced into the front oil pipe 41, the oil first enters one of the first inner cavities 101 and then flows through the first flow channel 13 into the other connected first inner cavity 101. When brake oil is introduced into the rear oil pipe 42, the oil first enters one of the second inner cavities 102 and then flows through the second flow channel 14 into the other connected second inner cavity 102.

[0043] Specifically, the housing 1 includes a first shell portion 11 and a second shell portion 12. Two first inner cavities 101 are respectively provided in the first shell portion 11 and the second shell portion 12, and two second inner cavities 102 are respectively provided in the first shell portion 11 and the second shell portion 12.

Specifically, one of the first inner cavities 101 and one of the second inner cavities 102 are provided in the first shell portion 11, and the other second inner cavities 102 and the other second inner cavities 102 are provided in the second shell portion 12.

[0044] Specifically, the first shell 11 is provided with a first branch channel and a third branch channel, and the second shell 12 is provided with a second branch channel and a fourth branch channel. The first branch channel communicates with the first inner cavity 101 in the first shell 11, and the second branch channel communicates with the first inner cavity 101 in the second shell 12. The first branch channel and the second branch channel together form a first flow channel 13. The third branch channel communicates with the second inner cavity 102 in the first shell 11, and the fourth branch channel communicates with the second inner cavity 102 in the second shell 12. The third branch channel and the fourth branch channel together form a second flow channel 14. When the first shell 11 and the second shell 12 are joined together, the first branch channel and the second branch channel are joined together to form the first flow channel 13. When the first shell 11 and the second shell 12 are joined together, the third branch channel and the fourth branch channel are joined together to form the second flow channel 14.

[0045] Specifically, a first sealing ring 151 is provided between the first and second lanes, and a second sealing ring 152 is provided between the third and fourth lanes. The first sealing ring 151 is provided between the first and second lanes to seal the gap between them. The second sealing ring 152 is provided between the third and fourth lanes to seal the gap between them.

[0046] Optionally, the material of the first sealing ring 151 and the second sealing ring 152 is set to rubber.

[0047] In this embodiment, the housing 1 defines a front main channel 16 and a rear main channel 17. A front oil pipe 41 communicates with the front main channel 16, and a rear oil pipe 42 communicates with the rear main channel 17. The front main channel 16 communicates with one of the first inner cavities 101, and the rear main channel 17 communicates with one of the second inner cavities 102. Specifically, the front oil pipe 41 is fixedly plugged into the front main channel 16 and communicates with one of the first inner cavities 101 through the front main channel 16. The rear oil pipe 42 is fixedly plugged into the rear main channel 17 and communicates with one of the second inner cavities 102 through the rear main channel 17.

[0048] Specifically, the front oil pipe 41 is fixed to the housing 1 via a first joint 181 and communicates with the front main flow channel 16. The rear oil pipe 42 is fixed to the housing 1 via a second joint 182 and communicates with the rear main flow channel 17. Specifically, the first joint 181 defines a first flow chamber, which communicates with the front main flow channel 16. The first joint 181 is fixed to the housing 1, and the front oil pipe 41 is fixedly connected to the first joint 181 and communicates with the first flow chamber. The second joint 182 defines a second flow chamber, which communicates with the rear main flow channel 17. The second joint 182 is fixed to the housing 1, and the rear oil pipe 42 is fixedly connected to the second joint 182 and communicates with the second flow chamber.

[0049] Furthermore, a first air release member 191 and a second air release member 192 are provided on the housing 1. The first air release member 191 communicates with the first inner cavity 101, and the second air release member 192 communicates with the second inner cavity 102. By providing the first air release member 191 and the second air release member 192, when brake oil is introduced into the first inner cavity 101, the gas remaining in the first inner cavity 101 can be promptly discharged. When brake oil is introduced into the second inner cavity 102, the gas remaining in the second inner cavity 102 can be promptly discharged.

[0050] Exemplarily, the first air release member 191 and the second air release member 192 are both configured as air release bolts.

[0051] In this embodiment, a first restoring member (not shown) and a second restoring member (not shown) are further included on the housing 1. The first restoring member causes the two front brake pads 211 to always tend to move away from each other, and the second restoring member causes the two rear brake pads 221 to always tend to move away from each other.

[0052] Specifically, the first return member includes two first springs, each corresponding to the two front brake pads 211. The first springs connect the housing 1 to the corresponding front brake pads 211. The second return member includes two second springs, each corresponding to the two rear brake pads 221. The second springs connect the housing 1 to the corresponding rear brake pads 221. The two first springs are adapted to force the two front brake pads 211 away from each other, thereby disengaging the brake disc, when the first piston releases the brake fluid. The two second springs are adapted to force the two rear brake pads 221 away from each other, thereby disengaging the brake disc, when the second piston releases the brake fluid.

[0053] This embodiment further provides a brake comprising the aforementioned brake caliper assembly and a brake disc, which is positioned between two front brake pads 211 and between two rear brake pads 221. The two front brake pads 211 can brake the brake disc when they are close together; and the two rear brake pads 221 can brake the brake disc when they are close together.

[0054] The brake uses the above-mentioned brake caliper assembly, so it can have all the beneficial effects of the brake caliper assembly, that is, the front brake pad group 21 and the rear brake pad group 22 can work independently or in conjunction with each other, and the independent operation and the coordinated operation do not interfere with each other, which can further improve the uniformity of braking force distribution when the driver brakes with both hands.
