Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle parts, in particular to a motorcycle brake disc protection device. Background Art

[0002] The motorcycle brake disc, usually referred to as the disc brake disc, is a key component in the motorcycle braking system. The disc brake disc slows down, stops or turns the wheel through the pressure of the brake caliper. Specifically, when the rider squeezes the brake handle, the brake system will generate pressure, push the piston in the caliper, and press the friction plate against the disc brake disc, thereby generating friction to slow down or stop the wheel. When a motorcycle is driving on the above-mentioned roads, especially on muddy rainy and snowy days, the brake disc and brake pads often stick to many dust particles or mud. In this way, when the brake disc and brake pads are eroded by rain and mud for a long time, the brake disc, especially the brake pad, will be severely worn when braking, shortening its service life. When the brake pads are worn, if you don't pay attention, it will also cause unsafe factors for the driver.

[0003] Chinese patent document CN2521138Y discloses a disc protection device for a motorcycle disc brake, wherein a tappet and a clamping plate that are clamped on a motorcycle shock absorber are arranged on an outer sealing plate, and an inner sealing plate is divided into two parts. By installing this protection device, a brake disc and a brake pad in the brake are completely placed in the protector, so that the brake disc and the brake pad are prevented from being contaminated with dust and mud, and the wear of the brake disc and the brake pad is reduced, thereby extending their service life.

[0004] The prior art has the following problems: In the above device, the outer sealing plate and the inner sealing plate are connected as a whole to fully cover the disc, which is troublesome for the user to check the working status of the disc. The protective device needs to be completely removed from the motorcycle frame, which is quite time-consuming. Secondly, in the above device, although dust and mud can be reduced from invading the disc, if the splashing mud is stained on the surface of the disc, it cannot be handled and removed in time, and the practicality is poor.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a motorcycle brake disc protection device includes a disc 1 and a frame 5, wherein the middle inner wall of the disc 1 is rotatably connected to the rear bottom of the frame 5, a brake assembly 2 is fixedly installed on the right bottom of the frame 5, a protective disassembly assembly 3 is fixedly installed on the front bottom of the frame 5, and a dust removal and cooling assembly 4 is fixedly installed on the front top of the protective disassembly assembly 3.

[0026] The disc 1 slows down, stops or turns the wheel through the brake assembly 2. The arc-shaped protective cover 31 and the arc-shaped connecting cover 32 can be quickly separated or assembled through the protective disassembly assembly 3, which is convenient for the user to observe the working status of the disc 1. At the same time, under normal circumstances, the arc-shaped protective cover 31 and the arc-shaped connecting cover 32 can wrap and protect the disc 1 to prevent the disc 1 from being disturbed by the external environment, thereby increasing the service life of the disc. The dust and dust splashed on the surface of the disc 1 can be removed by the dust removal and cooling assembly 4 using a micro high-pressure air pump 42 and a nozzle 45. The removed dust falls into the inner cavity of the arc-shaped protective cover 31, and will fly out due to the airflow generated when the disc 1 rotates. In the above process, the ejected high-pressure gas can not only clean the disc 1, but also cool it to a certain extent. It is highly practical and environmentally friendly and energy-saving.

[0027] like Figure 2 and Figure 3 As shown, the brake assembly 2 includes a brake caliper 21, the left portion of the brake caliper 21 is fixedly mounted to the right bottom of the frame 5, a piston mechanism 22 is fixedly mounted in the inner cavity of the brake caliper 21, and an oil inlet pipe 23 is fixedly mounted on the right portion of the piston mechanism 22.

[0028] The brake assembly 2 is an existing mechanism. When the rider brakes, by holding down the brake handle, the brake oil in the brake pump generates pressure. This pressure is transmitted to the piston mechanism 22 in the brake caliper 21 of each wheel through the fluid through the oil inlet pipe 23. The piston mechanism 22 drives the caliper to clamp the disc, thereby generating friction and slowing down the motorcycle.

[0029] like Figure 2 and Figure 4 As shown, the protective disassembly assembly 3 includes an arc-shaped protective cover 31 and an arc-shaped connecting cover 32. The front side of the arc-shaped protective cover 31 near its axis is movably installed on the front bottom of the frame 5. The bottom front and rear positions of the arc-shaped connecting cover 32 are fixedly installed with fixing plates 33. The top front and rear positions of the arc-shaped connecting cover 32 are provided with rectangular grooves 34. The lower ends of the two fixing plates 33 are plugged into the inner walls of the two rectangular grooves 34.

[0030] After the arc-shaped protective cover 31 is installed on the vehicle frame 5, the disc 1 can be framed inside, and the arc-shaped connecting cover 32 can be fitted with the arc-shaped protective cover 31 through two fixing plates 33, so as to facilitate the protection and connection work of the two.

[0031] like Figure 4 As shown, a mounting plate 35 is overlapped on the top of the outer wall of the arc-shaped protective cover 31, and the upper and lower parts of the left side of the mounting plate 35 are threadedly connected with connecting bolts 36 that pass through the top of the mounting plate 35, and threaded holes for matching the connecting bolts 36 are opened on the side where the outer walls of the arc-shaped protective cover 31 and the arc-shaped connecting cover 32 are close to each other.

[0032] The arc-shaped protection cover 31 can be separated from the arc-shaped connection cover 32 by screwing in or out the corresponding connection bolts 36 .

[0033] like Figure 4 As shown, the arc-shaped protective cover 31 and the arc-shaped connecting cover 32 are both located at the left half of the disc 1 , and the arc-shaped protective cover 31 and the arc-shaped connecting cover 32 semi-enclose the disc 1 .

[0034] The arc-shaped protective cover 31 and the arc-shaped connecting cover 32 cover the exposed left half of the disc 1 , which can effectively prevent the external environment from interfering with the working state of the disc 1 .

[0035] like Figure 4 As shown, a plurality of heat dissipation holes 37 are provided on the front and rear sides of the arc-shaped protection cover 31 and the arc-shaped connection cover 32 .

[0036] The plurality of heat dissipation holes 37 ensure that the arc-shaped protection cover 31 and the arc-shaped connection cover 32 do not affect the brake heat dissipation of the disc 1 when surrounding the disc 1 , and the practicability is strong.

[0037] like Figure 5 As shown, the dust removal and cooling component 4 includes a fixing frame 41, the rear side of the fixing frame 41 is fixedly installed on the front top of the arc-shaped protective cover 31, a micro high-pressure air pump 42 is fixedly installed on the front middle of the fixing frame 41, and an air storage tank 43 is fixedly installed on the front left of the fixing frame 41, and the output end of the micro high-pressure air pump 42 is connected to the input end of the air storage tank 43.

[0038] The micro high-pressure air pump 42 is an existing mechanism that can compress air to a required high-pressure state, and the air storage tank 43 can store the high-pressure gas to ensure that it can be quickly released when needed.

[0039] like Figure 5 As shown, an air pipe 44 is fixedly installed on the top of the inner wall of the arc-shaped protective cover 31, the front end of the air pipe 44 passes through the front part of the arc-shaped protective cover 31 and is fixedly connected to the output end of the gas storage tank 43, and nozzles 45 are fixedly installed on the front and rear parts of the outer wall of the air pipe 44.

[0040] A solenoid valve needs to be installed near the disc 1 or on the frame 5. The input end of the solenoid valve is fixedly connected to the output end of the gas tank 43, and the output end of the solenoid valve is connected to the gas pipe 44. It can control the injection timing and injection amount of the high-pressure gas, and can be precisely controlled by receiving signals from the vehicle control system. Two nozzles 45 can spray high-pressure gas on the upper and lower surfaces of the disc 1, and dust on the surface of the disc 1 can be removed during the rotation of the disc 1.

[0041] The working principle of the utility model is as follows: after the arc-shaped protective cover 31 is installed on the frame 5 by means of specific bolts, the disc 1 can be framed inside, and the arc-shaped connecting cover 32 can be fitted with the arc-shaped protective cover 31 by means of two fixing plates 33, so as to facilitate the protective function and connection work of the two, and then the arc-shaped protective cover 31 can be connected with the arc-shaped connecting cover 32 by screwing in two connecting bolts 36.

[0042] When the vehicle needs to remove dust and cool the disc 1, the vehicle control system sends a signal to the solenoid valve, which opens quickly to allow the high-pressure gas in the gas tank 43 to be ejected through the nozzle 45. The high-pressure jet airflow can effectively blow away the dust and impurities on and around the disc 1 and take away some heat, thereby reducing the temperature of the disc 1. At the same time, the jet airflow can also increase the wetness of the surface of the disc 1 to a certain extent, which helps to improve the braking performance.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
