Description

Technical Field

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

[0002] With the continuous improvement of national emissions, people's energy-saving and environmental protection requirements, and people's requirements for automobile energy consumption; reducing the driving resistance of the whole vehicle and reducing energy consumption are becoming more and more concerned; among them, the drag force of the brake is also one of the energy consumption of the whole vehicle.

[0003] At present, floating caliper disc brakes are widely used in passenger cars and commercial vehicles. After the current floating caliper disc brake is released, the friction pad often cannot be fully separated from the brake disc. Therefore, during driving, the friction pad and the brake disc are still in contact and the friction generated forms a drag force during driving, resulting in energy loss during driving. In order to solve the problem of drag force, the inner friction pad on the current floating caliper disc brake can be connected to the brake caliper piston cylinder through a claw. When the brake caliper piston cylinder returns, it can directly drive the inner friction pad to return. However, only the inner friction pad of the current floating caliper disc brake can return actively, and the outer friction pad still has the problem of drag force. Utility Model Content

[0004] The utility model aims to provide a floating caliper disc brake to overcome the problem of dragging force on the outer friction plate of the floating caliper disc brake in the prior art.

[0005] The utility model is implemented by adopting the following technical scheme: a floating caliper disc brake comprises a brake caliper body bracket, inner friction plates and outer friction plates are slidably mounted on both sides of the brake caliper body bracket respectively, an elastic member is fixedly mounted on the middle of the outer friction plate, the elastic member comprises a base plate connected to the outer friction plate, the bottom of the base plate is bent upwardly through a bending portion and connected to a C-shaped buckle, the opening of the buckle is arranged downward, the brake caliper body bracket is provided with a cross bar on the outer side of the outer friction plate, and the buckle is clamped on the cross bar.

[0006] Furthermore, a slide groove is provided on the brake caliper body bracket, and sliders inserted into the slide groove are respectively installed on both sides of the outer friction plate, and sliders inserted into the slide groove are respectively installed on both sides of the inner friction plate.

[0007] Furthermore, the base plate is riveted to the outer friction plate.

[0008] Furthermore, the base plate is bent upwards in sequence through the bending portion toward one side of the buckle to connect to at least one U-shaped segment, and the base plate is bent through the rearmost U-shaped segment to connect to the buckle.

[0009] Furthermore, the base plate is bent upward in sequence through the bending portion to connect the two U-shaped sections.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model installs an elastic member between the outer friction plate and the brake caliper body bracket. When the brake caliper body on the brake caliper body bracket drives the outer friction plate to move toward the brake disc and contact the brake disc, the elastic member is in a compressed state, that is, the buckle moves toward the base plate through the bent portion, and the bent portion is elastically deformed. When the brake caliper body does not push the outer friction plate toward the brake disc, the elastic member recovers and elastically pulls the outer friction plate to quickly separate from the brake disc, thereby reducing the drag force.

[0012] 2. The utility model fixes the elastic member at the middle of the outer friction plate, so only one elastic member is needed during production, thus reducing production costs.

[0013] 3. The utility model facilitates the installation of the elastic member by making the base plate connected in a C-shaped buckle. During installation, it is only necessary to clamp the buckle on the cross bar, thus avoiding the process of drilling holes and installing bolts on the brake caliper body bracket, reducing the installation process and improving the installation efficiency.

[0014] 4. The elastic member of the utility model also has the advantage of being easy to disassemble, so it is convenient to replace the elastic member after it is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] A floating caliper disc brake comprises a brake caliper body bracket 1, an inner friction plate 2 and an outer friction plate 3 are slidably mounted on both sides of the brake caliper body bracket 1, an elastic member 4 is fixedly mounted in the middle of the outer friction plate 3, the elastic member 4 comprises a base plate 5 connected to the outer friction plate 3, the bottom of the base plate 5 is bent upward through a bending portion 6 and connected to a C-shaped buckle 7, the opening of the buckle 7 is set downward, the brake caliper body bracket 1 is provided with a cross bar 8 on the outer side of the outer friction plate 3, and the buckle 7 is clamped on the cross bar 8.

[0022] When the utility model is in use, the brake caliper body bracket 1 is fixed on the automobile body, and the brake caliper body bracket 1 is also installed with a brake caliper body 12. A brake disc is arranged between the outer friction plate 3 and the inner friction plate 2, and the brake disc and the outer friction plate 3 and the inner friction plate 2 are all clearance-matched. When the brake caliper body 12 drives the outer friction plate 3 to move toward the brake disc and contacts the brake disc, the elastic member 4 is in a compressed state, that is, the buckle 7 moves toward the substrate 5 through the bent portion 6, and the bent portion 6 undergoes elastic deformation. When the brake caliper body 12 does not push the outer friction plate 3, the bent portion 6 on the elastic member 4 returns to the initial state, and the outer friction plate 3 is quickly separated from the brake disc by elastic pulling, thereby reducing the drag force. The utility model fixes the elastic member 4 in the middle of the outer friction plate 3, and only one elastic member 4 can be used, thereby reducing the number of elastic members 4 used and reducing production costs. The utility model facilitates the installation of the elastic member 4 by connecting the base plate 5 to the C-shaped buckle 7. During installation, the buckle 7 only needs to be clamped on the cross bar 8, avoiding the process of drilling holes and installing bolts on the brake caliper body bracket 1, reducing the installation process and improving the installation efficiency. The elastic member 4 of the utility model also has the advantage of being easy to disassemble, which is convenient for replacing the elastic member 4 after it is damaged.

[0023] The brake caliper body bracket 1 is provided with a slide groove 9 , and sliders 10 inserted into the slide groove 9 are respectively installed on both sides of the outer friction plate 3 , and sliders 10 inserted into the slide groove 9 are respectively installed on both sides of the inner friction plate 2 .

[0024] The utility model provides a slide groove 9 on the brake caliper body bracket 1, and respectively installs a slider 10 matched with the slide groove 9 on the outer friction plate 3 and the inner friction plate 2, so that the outer friction plate 3 and the inner friction plate 2 can move more smoothly relative to the brake caliper body bracket 1.

[0025] The base plate 5 is riveted to the outer friction plate 3 .

[0026] The base plate 5 is bent upward in sequence through the bending portion 6 to connect to at least one U-shaped segment 11 , and the base plate 5 is bent and connected to the buckle 7 through the rearmost U-shaped segment 11 .

[0027] The utility model can effectively enhance the elastic force and rebound effect of the elastic member 4 and effectively increase the rebound stroke of the elastic member 4 by providing at least one U-shaped section 11, thereby ensuring that the elastic member 4 can be used normally after a certain friction loss occurs on the outer friction plate 3.

[0028] The base plate 5 is bent upward in sequence through the bending portion 6 to connect the two U-shaped sections 11 .
