Description

Technical Field

[0001] The present invention relates to the technical field of vehicle cooling, and more particularly to a cooling device for a brake system of a vehicle operating in mountainous areas. Background Art

[0002] Mountainous terrain is steep, and vehicles (especially heavily loaded ones) must constantly brake to control speed on long downhill sections. Frequent braking causes intense friction between the brake pads and the disc / drum, converting kinetic energy into heat. If this heat cannot be dissipated quickly, the brake system temperature can rise dramatically (up to hundreds of degrees Celsius), leading to performance degradation or even failure.

[0003] In the prior art, a Chinese patent with publication number CN222391819U discloses a brake pad cooling device for an electric vehicle. A brake pad is provided between the rear axle and the rear wheel. A water inlet pipe and a breathing tube are provided on the top of a water tank. A water outlet pipe is provided on the bottom of the water tank. A bracket fixes the water tank to the vehicle frame. A water pump is provided on the top of the water tank. The water outlet of the water pump is connected to a nozzle through a pipe. The water is pressurized by the water pump and transmitted to the nozzle through the pipe, and the cooling water is sprayed directly onto the brake pad.

[0055] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0056] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0057] Example 1:

[0058] like Figure 1 As shown, the present invention provides a cooling device for a brake system of a mountainous operation vehicle, comprising:

[0059] A water tank 1, a water pipe 2, a control switch 3 and a temperature monitoring device, wherein the water tank 1 is arranged on the top of the cab of the working vehicle 5; the top of the water pipe 2 is connected to the water tank 1, and the water pipe 2 forms multiple branches at the bottom after passing through the cab, and the multiple branches extend to the brake pads of each wheel respectively; the detection end of the temperature monitoring device is arranged close to the brake pad; the control switch 3 is arranged on the water pipe 2 inside the cab; the display screen 4 of the temperature monitoring device is arranged in the cab.

[0060] The working principle and beneficial effects of the above technical solution are:

[0061] The present invention provides a cooling device for the brake system of a mountain work vehicle. A water tank 1 is arranged on the top of a working vehicle 5 cab and can be fixed by rope binding or a fixed bracket; the top of a water pipe 2 is connected to the water tank 1, and after passing through the cab, the bottom is fixed near the wheel brake pad, so that the pipe mouth is aligned with the brake pad; a control switch 3 is arranged on the water pipe 2 inside the cab, in a position that is easy for the driver to access, so that the brake pad can be turned on at any time to cool the brake pad; the detection end of the temperature monitoring device is arranged as a temperature sensor, the temperature sensor is located near the brake pad and is used to detect the temperature of the brake pad; the display screen 4 of the temperature monitoring device is arranged near the instrument panel in the cab, so that the driver can observe the brake pad temperature at any time. The display screen 4 and the temperature sensor are connected to the control main board through a cable.

[0062] When the work vehicle is traveling on a continuous downhill section, the driver observes abnormal brake pad temperature through the display screen 4 of the temperature monitoring device. The driver turns on the control switch 3 on the water pipe 2. The water in the water tank 1 flows downward under the action of gravity, flows along the water pipe 2 to the wheel brake pad, and cools the brake pad.

[0063] Through the above structural design, the water tank 1 is set on the top of the cab of the working vehicle 5. When the temperature of the brake pad is abnormal, the water flows onto the brake pad by gravity to cool the brake pad. No additional driving source is required, which is green and environmentally friendly. The temperature of the brake pad is monitored in real time by a temperature sensor and displayed on the display screen 4, which makes it easy to observe the temperature status of the brake pad at any time and determine the timing of the cooling operation.

[0064] Example 2:

[0065] Based on the above embodiment 1, the water pipe 2 is made of flexible materials such as PVC and rubber.

[0066] The working principle and beneficial effects of the above technical solution are:

[0067] The water pipe 2 is made of a soft material such as PVC or rubber, which is convenient for wiring arrangement on the work vehicle.

[0068] Example 3:

[0069] Based on the above embodiment 1, the temperature monitoring device includes a control module, which includes:

[0070] An acquisition unit, used to acquire the temperature detection result of each brake pad through a temperature sensor during driving;

[0071] An evaluation unit, configured to evaluate temperature abnormalities at each brake pad based on the temperature detection results at each brake pad obtained by the acquisition unit and compared with a preset temperature range;

[0072] The alarm unit is used to give an alarm for abnormal temperature according to the temperature evaluation result of each brake pad by the evaluation unit, and the alarm information is displayed on the display screen 4.

[0073] The working principle and beneficial effects of the above technical solution are:

[0074] The acquisition unit obtains the temperature of each brake pad through the temperature sensor. When the temperature value is within the preset temperature range, the evaluation unit determines that the current temperature is normal, and only the temperature information is displayed on the display screen 4 without an alarm; when the temperature value exceeds the preset temperature range, the evaluation unit determines that the current temperature is abnormal, and the temperature information is displayed on the display screen 4, and an alarm is displayed to provide an intuitive prompt to the driver.

[0075] Example 4:

[0076] like Figure 3 As shown, based on the above embodiment 1, a water tank pressure plate 7 is provided in the water tank 1. The water tank pressure plate 7 is slidably provided on the inner wall of the water tank 1 and presses on the surface of the cooling water.

[0077] The working principle and beneficial effects of the above technical solution are:

[0078] A water tank pressure plate 7 is provided in the water tank 1, and the water tank pressure plate 7 presses on the water surface to provide stable pressure for the cooling water, so that the cooling water flows along the water pipe 2 under the action of gravity and constant pressure, thereby achieving stable water discharge.

[0079] Example 5:

[0080] like Figure 2-Figure 6 As shown, based on the above embodiment 4, an energy storage and pressurization unit is provided on the water tank 1, and the energy storage and pressurization unit includes:

[0081] The booster seat 11 is arranged at the top of the water tank 1. A booster chamber 12 is provided inside the booster seat 11, and the booster output end of the booster seat 11 is connected to the water tank pressure plate 7;

[0082] The movable boosting cylinder 13 , multiple movable boosting cylinders 13 are connected to the bottom plate of the boosting seat 11 , the movable boosting cylinder 13 is suspended above the water tank 1 , and the air outlet of the movable boosting cylinder 13 is connected to the boosting chamber 12 through the boosting pipeline 14 .

[0083] The active boost cylinder 13 comprises:

[0084] One-way air inlet and one-way air outlet, the one-way air inlet and one-way air outlet are located on the upper part of the movable booster cylinder 13, the one-way air inlet is connected to the external environment, and the one-way air outlet is connected to the booster pipeline 14;

[0085] The piston rod 15 is slidably connected to the bottom of the movable booster cylinder 13. The bottom end of the piston rod 15 extends out of the movable booster cylinder 13 and extends vertically downward. The piston rod 15 is located outside the water tank 1;

[0086] The elastic return member 16 is connected between the top wall of the movable booster cylinder 13 and the top end of the piston rod 15 .

[0087] The working principle and beneficial effects of the above technical solution are:

[0088] Water in water tank 1 flows by gravity onto the brake pads. When the work vehicle 5 travels in mountainous terrain, the uneven terrain can cause the cooling water in the water tank to float up and down, affecting the stability of the cooling water discharge. An energy storage and boosting unit is installed on the water tank 1. During operation, the boosting seat 11 is mounted on the top of the water tank 1, forming a boosting chamber within the boosting seat 11. A movable boosting cylinder 13 on the boosting seat 11 is suspended above the water tank 1. As the work vehicle 5 jolts and jolts, the piston rod 15 within the movable boosting cylinder 13 oscillates up and down. As the piston rod 15 oscillates downward, negative pressure is generated within the movable boosting cylinder 13, drawing in air from the outside environment through the one-way air inlet. As the piston rod 15 oscillates upward, it pushes the air inside the movable boosting cylinder 13 upward, forcing air into the boosting chamber 12 through the boosting line 14. The increased pressure within the boosting chamber 12 acts on the water tank pressure plate 7, increasing the surface pressure of the cooling water. The elastic return member 16 provides elastic force for the piston rod 15 so that the piston rod 15 can return to its original position after shaking.

[0089] Through the above-mentioned structural design, the working vehicle 5 automatically increases the pressure inside the boost seat 11 during movement, acts on the water tank pressure plate 7, reduces the rising of the water surface during driving, supplements the pressure of the cooling water, and ensures that the cooling water is stably and continuously delivered to the brake pads, solving the problems of flow interruption and unstable water flow caused by the floating of the cooling water.

[0090] Example 6:

[0091] like Figure 2-Figure 5 As shown, based on the above embodiment 5, a counterweight wheel 17 is connected to the bottom of the piston rod 15, and the counterweight wheel 17 is wrapped with a rubber layer.

[0092] The working principle and beneficial effects of the above technical solution are:

[0093] A counterweight wheel 17 is provided at the bottom of the piston rod 15 to increase the weight of the piston rod 15. During bumpy driving, the swing amplitude of the piston rod 15 can be increased to improve the supercharging effect. A rubber layer is provided on the counterweight wheel 17 to reduce the damage caused by collision between the counterweight wheel 17 and the surface of the water tank 1.

[0094] Example 7:

[0095] like Figure 2-Figure 5As shown, based on the above embodiment 5, a plurality of telescopic frame assemblies are provided on the booster seat 11, and the telescopic frame assemblies include:

[0096] A first support arm 19, which is connected to the bottom plate of the booster seat 11, and a first plate 22 is provided on the outer side of the first support arm 19;

[0097] A second support arm 21, one end of which is connected to the movable booster cylinder 13, and the other end of which is sleeved on the first support arm 19 and slidably connected thereto. A second plate 23 is provided on the outer side of the second support arm 21;

[0098] The tensioning rod 24 has one end connected to the second plate 23 and the other end slidingly arranged in the through hole of the first plate 22. A tensioning spring 25 is sleeved on the tensioning rod 24, and the two ends of the tensioning spring 25 are respectively connected to the first plate 22 and the second plate 23.

[0099] The working principle and beneficial effects of the above technical solution are:

[0100] A telescopic frame assembly is provided on the booster seat 11. The two support arms of the telescopic frame assembly are in a relatively sliding state, and the tension spring 25 tends to squeeze the two support arms away from each other. When the second support arm 21 slides on the first support arm 19, it pulls the tension rod 24 to move and compress the tension spring 25. Through the above structural design, by adjusting the position of the second support arm 21 on the first support arm 19, the total length of the entire support arm can be adjusted, thereby adjusting the distance between the active booster cylinder 13 and the center of the booster seat 11, changing the cantilever length of the active booster cylinder 13. Increasing the cantilever length increases the instability of the piston rod 15 in the active booster cylinder 13, making the piston rod 15 shake more significantly, thereby adjusting the boost intensity.

[0101] Example 8:

[0102] like Figure 2-Figure 5 As shown, based on the above embodiment 7, the telescopic frame assembly further includes:

[0103] A plurality of rotating shafts 18 are rotatably connected to the bottom plate of the booster seat 11, and the rotating shafts 18 pass through the end of the first support arm 19, wherein the top end of any rotating shaft 18 is connected to the adjustment handle;

[0104] Pulley 26, the pulley 26 is connected to the rotating shaft 18, and multiple pulleys 26 are connected by a synchronous belt 27;

[0105] The rope pulley 28 is connected to the rotating shaft 18 . A pull rope 29 is wound around the rope pulley 28 , and the other end of the pull rope 29 is connected to the movable booster cylinder 13 .

[0106] The working principle and beneficial effects of the above technical solution are:

[0107] When the telescopic frame assembly is in use, the adjustment handle is used to rotate any one of the rotating shafts 18, causing the pulley 26 and rope pulley 28 on the rotating shaft 18 to rotate synchronously. The pulley 26 then drives the other multiple pulleys 26 to rotate synchronously via the synchronous belt 27, causing the rotating shafts 18 and rope pulleys 28 corresponding to the other pulleys 26 to rotate synchronously. The pull rope 29 on the rope pulley 28 is wound, tightened, or released, pulling the booster cylinder 13 toward or away from the center of the booster seat 11. The second support arm 21 slides on the first support arm 19, shortening or lengthening the entire support arm, thereby achieving synchronous adjustment of the positions of multiple booster cylinders 13.

[0108] Example 9:

[0109] like Figure 4 As shown, based on the above-mentioned embodiment 8, a tensioning wheel 31 is installed on the bottom plate of the booster seat 11, and the synchronous belt 27 is arranged around the tensioning wheel 31.

[0110] The working principle and beneficial effects of the above technical solution are:

[0111] The tensioning wheel 31 tensions the synchronous belt 27 to ensure the tension on the synchronous belt 27 and reduce the slippage of the pulley 26.

[0112] Example 10:

[0113] like Figure 3 、 Figure 6 As shown, based on the above embodiment 5, the booster seat 11 includes:

[0114] A guide rod 32 is connected to the top of the booster seat 11, and a limit block 33 is provided on the top of the guide rod 32. A return spring 35 is sleeved on the guide rod 32;

[0115] A first pressing plate 34 is slidably connected to the guide rod 32 , and a return spring 35 is connected between the first pressing plate 34 and the limit block 33 ;

[0116] A plurality of pressure rods 36 are connected to the bottom end of the first pressure plate 34 and extend into the interior of the booster seat 11;

[0117] The second pressing plate 37 is slidably connected to the booster seat 11. The second pressing plate 37 and the upper part of the booster seat 11 are surrounded by a booster chamber 12. The second pressing plate 37 is connected to the bottom end of the pressure rod 36;

[0118] The pressure relief hole 38 is provided on the side wall of the booster seat 11 and is located below the second pressure plate 37;

[0119] The transmission column 39 is vertically connected to the bottom end of the second pressure plate 37 and extends into the water tank 1.

[0120] The working principle and beneficial effects of the above technical solution are:

[0121] Air is injected into the boost chamber 12 through the boost line 14, increasing the pressure within the boost chamber 12. Due to the presence of cooling water in the water tank 1, the second pressure plate 37 and the transmission column 39 press the water tank pressure plate 7 against the water surface and prevent it from moving downward. After the control switch 3 is turned on to allow water to flow from the water pipe 2, the water level in the water tank 1 decreases as the water flow continues, causing the water tank pressure plate 7 to move downward. Under the action of the air pressure within the boost chamber 12, the second pressure plate 37 and the transmission column 39 also move downward, supplementing the pressure of the outflowing cooling water. When the second pressure plate 37 moves, it drives the pressure rod 36 to move downward synchronously, and the pressure rod 36 drives the first pressure plate 34 to move downward and stretches the reset spring 35; when the second pressure plate 37 moves over the pressure relief hole 38, the air in the boost chamber 12 is discharged through the pressure relief hole 38, and the air pressure in the boost chamber 12 is reduced. Under the elastic force of the reset spring 35, the first pressure plate 34, the pressure rod 36, the second pressure plate 37 and the transmission column 39 are reset, and then the pressure is accumulated again; when the pressure reaches a certain value, the transmission column 39 is pushed downward again to pressurize the cooling water in the water tank 1 again.

[0122] Example 11:

[0123] like Figure 3 、 Figure 7 As shown, based on the above embodiment 10, the water tank pressure plate 7 includes:

[0124] Support sleeve 41, support sleeve 41 is connected to the top of water tank pressure plate 7, and transmission column 39 extends into support sleeve 41;

[0125] Limiting clips 42, multiple limiting clips 42 are evenly arranged in the support sleeve 41, the bottom ends of the limiting clips 42 are hinged to the inner wall of the support sleeve 41, and the top ends are inclined toward the central transmission column 39. The transmission column 39 is evenly provided with limiting teeth 43, and the limiting clips 42 are engaged between adjacent limiting teeth 43;

[0126] The elastic telescopic rod 44 is connected between the inner wall of the supporting sleeve 41 and the limiting clamping plate 42 .

[0127] The working principle and beneficial effects of the above technical solution are:

[0128] A support sleeve 41 structure is provided on the water tank pressure plate 7, and a transmission column 39 is provided at the center of the support sleeve 41. The tops of the plurality of limit clamps 42 are retracted toward the center, and are clamped between the two limit clamps 43 of the transmission column 39 under the action of the elastic telescopic rod 44. When the transmission column 39 moves downward, the limit clamps 42 are squeezed by the limit clamps 43, pushing the water tank pressure plate 7 downward to achieve pressurization of the cooling water. When the boost chamber 12 is depressurized, the transmission column 39 moves upward, and the limit clamps 43 on the transmission column 39 slide relative to the limit clamps 42, squeezing the top of the limit clamps 42 to expand. The water tank pressure plate 7 remains stationary under the action of gravity and the adsorption force of the water surface, and the transmission column 39 moves upward to reset.

[0129] Through the above-mentioned structural design, the transmission column 39 and the support sleeve 41 form a one-way transmission structure, and the reciprocating motion of the second pressure plate 37 intermittently applies pressure to the water tank pressure plate 7. The single movement amount of the second pressure plate 37 is controlled so that the second pressure plate 37 stops and resets each time after passing through the pressure relief hole 38. This ensures that the movement amount of the transmission column 39 each time it squeezes the support sleeve 41 remains consistent, that is, the pressurization intensity of each action is consistent, which can adapt to the water consumption of a single cooling process. Compared with the method of directly injecting air into the water tank 1 to increase the pressure, this method can maintain the position of the water tank pressure plate 7 stable, better control the pressure in the water tank 1, prevent the generation of excessive spray pressure, and improve the cooling effect on the brake pads.
