Description

Technical Field

[0001] This utility model relates to the field of brakes, and in particular to a wear-resistant wedge brake. Background Technology

[0002] A wedge brake is a device that uses the mechanical action of a wedge-shaped block to achieve braking, belonging to the category of friction brakes. Its core principle is to amplify a small input force into a larger clamping force through the wedge effect, thereby making close contact between the brake pads and the brake disc or brake drum, and achieving deceleration or stopping through friction.

[0003] Patent CN210859627U discloses a wedge-shaped brake. When the brake needs to be closed, the power mechanism is activated to bring the brake pads together. When the friction surface of the brake pads contacts the brake disc, friction is generated, causing the brake disc to decelerate. When the gap between the brake pads is less than the thickness of the brake disc, the brake pads clamp the brake disc, stopping its rotation. When the brake needs to be opened, the power mechanism is activated to move the brake pads apart. When the gap between the brake pads is greater than the thickness of the brake disc, the friction disappears, and the brake is fully opened. However, during the braking process, the friction between the brake pads and the brake disc is relatively small, which affects the braking effect. Furthermore, the wear resistance of the brake pad friction surface is relatively poor after long-term use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wear-resistant wedge brake. In the existing wedge brake, the friction between the brake pads and the brake disc is small during the braking process, which will affect the braking effect of the brake. Moreover, the wear resistance of the brake pad friction surface will be poor after long-term use.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a wear-resistant wedge brake, including a main body disc, and two sets of rotating plates located on one side of the main body disc. A drum is fixedly connected to the periphery of the rotating plates. Several sets of wear-resistant plates and several sets of wear-resistant strips are fixedly connected to the outer side of the drum. A connecting groove is provided on the top of one side of the main body disc. Two sets of movable blocks are provided inside the connecting groove. A first connecting rod is fixedly connected to the movable block. A connecting plate is fixedly connected to the other end of the first connecting rod. A second connecting rod is fixedly connected to the connecting plate.

[0006] A sleeve is securely connected to the top of the main body disc, and a brake caliper is securely connected to the other end of the sleeve. A piston rod is fixedly connected to the output end of the brake caliper, and a push plate is fixedly connected to the other end of the piston rod. A push rod is fixedly connected to the push plate, and a wedge block is fixedly connected to the other end of the push rod. Two sets of movable wheels are movably connected to the wedge block.

[0007] As a further embodiment of this utility model: the cross-sectional shape of the drum plate is arc-shaped, and several sets of wear-resistant plates and several sets of wear-resistant strips are distributed at equal intervals on the drum plate, and the several sets of wear-resistant plates and several sets of wear-resistant strips are staggered, and the cross-sectional shape of the wear-resistant plate is arc-shaped.

[0008] As a further embodiment of this utility model: the push plate is located inside the sleeve, the movable wheel and the movable block roll in contact, the second connecting rod is fixedly connected to the drum plate, and the first connecting rod is movably connected to the connecting groove.

[0009] As a further embodiment of this utility model: a first fixing plate and a second fixing plate are fixedly connected to both ends of the rotating plate, a first return spring is fixedly connected between the two sets of the first fixing plates, and a second return spring is fixedly connected between the two sets of the second fixing plates.

[0010] As a further embodiment of this utility model: connecting plates are fixedly connected to both sides of the connecting groove, four sets of connecting rods are fixedly connected to the top of one side of the main body disk, and the ends of the four sets of connecting rods are threaded with second threaded rings. Two sets of fixed shafts are fixedly connected to the bottom of one side of the main body disk, and the ends of the two sets of fixed shafts are threaded with first threaded rings.

[0011] As a further embodiment of this utility model: the connecting plate is movably connected to two sets of connecting rods, and the second threaded ring is located on the outside of the connecting plate.

[0012] As a further embodiment of this utility model: the bottom of the rotating plate is provided with a movable hole, and the rotating plate is movably connected to the fixed shaft through the movable hole, and the first screw ring is located on the outside of the rotating plate.

[0013] Compared with the prior art, the beneficial effects of this utility model include: the piston rod is moved by the brake cylinder, which in turn moves the push plate and push rod together inside the sleeve, thereby moving the wedge block. Through the cooperation of the wedge block and two sets of movable wheels, the two sets of movable blocks move relative to each other along the connecting groove. Then, through the cooperation of the first connecting rod and the connecting plate with the second connecting rod, the two sets of rotating plates move away from each other. Through the movable connection of the fixed shaft and the rotating plate, the two sets of drums rotate relative to each other until braking is achieved with the cooperation of several sets of wear-resistant plates and several sets of wear-resistant strips arranged in an alternating manner. This can improve the braking effect of the brake while performing wedge braking operation, and has better wear resistance.

[0014] Compared with the prior art, the beneficial effects of this utility model include: firstly, the first screw ring is screwed off from the fixed shaft, and then the rotating plate is separated from the fixed shaft through the movable hole. Next, the second screw ring is screwed off from the connecting rod, and the connecting groove is separated from the connecting disc through the cooperation of the connecting plate and the connecting rod. At this time, both sets of drums are separated from the main disc, realizing the quick disassembly function of the wedge brake, so as to inspect and replace the brake structure.
