Description

M275136 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to a hydraulic anti-lock brake system for locomotive, especially a type of locomotive's original brake pipeline embedded with low manufacturing cost, small volume, Improver of hydraulic anti-lock brake system for locomotive with easy assembly, environmental protection and low energy consumption. [Previous technology] According to the current, the production technology of locomotive on the market has been greatly improved, and the dynamic performance of locomotive has also been gradually improved. While the power has been greatly improved, the braking capacity and dynamic motion characteristics of locomotive have become more important. The locomotive manufacturer developed an ABS brake device for locomotive in order to prevent the locomotive from braking when the locomotive was locked by the emergency brakes, which caused the locomotive to slip out of control. Because the locomotive brake device has two types: mechanical drum brake and hydraulic disc brake, the corresponding ABS system is also different. The mechanical brake device has mechanical ABS and hydraulic brake. The device corresponds to a hydraulic ABS. The types of general hydraulic ABS can be divided into two types: circulating type and volume modulation type. Due to the large number of components, large installation volume, and high production cost, circulating type systems are commonly used in automobiles and are not applicable. On the locomotive. The volume-modulated system will accumulate oil after a long period of use, which saturates the brake oil in the pipeline and fails to return the brake oil to the brake master cylinder, resulting in insufficient fuel required for re-braking. In order to improve the lack of the aforementioned ABS braking device for locomotives, the inventor has successively obtained the Republic of China's new patent No. 18364, "Improvement of Locomotive ABS Brake Device", and the Republic of China's New Patent No. 191523

Page 6 M275136 4. Creation instructions (2) "Improvement of hydraulic anti-lock brake system for locomotive", the new patent of the Republic of China No. 22052 "locomotive hydraulic anti-lock brake system". Please refer to the first figure, which is a schematic sectional view of No. 2052 "locomotive hydraulic anti-lock brake system". As shown in the figure, the brake device 1 includes a control brake disc 1 1-action pressure regulating circuit mechanism 2 and a power control mechanism 13; and the circuit mechanism 12 includes a body 120 'with a channel 12 in it, and a valve shaft 122 in a channel 121 of the body 120, Among them, the body 1 2 0 is provided with an oil inlet 1 2 3 that can communicate with the channel 1 2 1 and the brake 1 4, and an oil outlet 124 that can communicate with the channel 1 2 1 and the brake disc 1 1. A communication pipe '125 is provided in the circuit mechanism 12, and the communication pipe 1 2 5 is provided for connecting the oil inlet 1 2 3 and the oil outlet 1 2 4 and prevents the valve shaft 1 2 2 from being generated. The rotation is provided with anti-rotation fixed blocks 1 2 6 at the bottom of the channel 1 2 1; the power control mechanism 1 3 has a rotation control shaft 1 3 1 that can push against the valve shaft 1 2 2 and a drive screw control shaft 1 3 1Motion power motor 1 3 2 ′ An electric control unit 133 that controls the rotation of the power motor. Continue to refer to the first figure, and cooperate with the second figure, which is a schematic diagram of the operation of a preferred embodiment of the new patent No. 2052 "locomotive hydraulic anti-lock brake system" of the Republic of China, as shown in the figure As shown in the first figure, when the driver presses the brake lever sharply, the brake oil flows from the brake 14 through the oil inlet 1 2 3 and then through the connecting channel 1 2 5 to the oil outlet 1 2 4 Then flow to the brake disc 1 1 1 with the brake disc 1 1 'for the brake disc 111 111 to lock the wheel 15 disc 1 5 1 and generate resistance to the disc 1 1 to reduce the wheel 1 5 speed to complete the braking action; continued as shown in the second figure, when the electric control unit of the power control mechanism 1 3} 3 3 senses that the instantaneous braking speed has exceeded the locomotive ABS brake

M275136_ IV. Creation instructions (3) When the system starts, the electric control unit 1 3 3 will automatically control the power motor 1 3 2 to run, and the power motor 1 3 2 will drive the screw control shaft 1 3 1 to run and push against the valve shaft. 1 2 2 moves in the channel 1 2 1 of the body 1 2 0, using the displacement generated by the valve shaft 1 2 2 to increase the volume of the brake oil pipeline, and reduce the brake oil in the brake disc 1 1 1 The pressure can be used to relieve the pressure. By disengaging the brake caliper 111 from the disc brake 1 5 1 of the brake wheel 15, the braking resistance is reduced, and the action of releasing the disc brake 1 5 1 is completed; thus, the brake resistance is increased. And in the process of reducing the braking resistance from time to time, the braking effect of the locomotive ABS braking system is achieved. Please refer to the second figure again, because the brake device 1 does not close the original brake pipeline of the locomotive, the lowest position of the valve shaft 1 2 2 can be lowered as shown in FIG. 1 and will not hinder the connecting channel 1 2 5 The internal brake oil flows. Therefore, if the power motor 1 3 2 of the power control mechanism 1 3 fails, only the brake device 1 loses the function of releasing the brake differential pressure, that is, the brake 1 4 can still pass through the oil inlet 1 2 3 Through the channel 1 2 5 to the oil outlet 1 2 4 and continuously supplying oil to the brake disc 1 1, the original brake function of the locomotive will not be affected and the brake action can still be performed. However, the Republic of China's new patent No. 2052 "locomotive hydraulic anti-lock brake system" still has the following unsatisfactory features, which are explained in order as follows: 1 · The problem of vibration of the brake handle: due to the brake device During operation 1, the brake fluid in the connecting channel 1 2 5 is not blocked, so the driver will feel the vibration caused by the pressure change caused by the operation of the brake device 1 when pressing the brake handle. This phenomenon is likely to cause the driver The panic releases or holds the brake handle, causing the vehicle to lose its brakes

Page 8 M275136 IV. Creative Instructions (4) Danger due to vehicle capacity. 2 · Excessive power consumption: Because the brake device 1 does not block the flow of brake oil in the connecting channel 1 2 5, the power of the power motor 1 2 2 must be greater than that of all the brake oil in the brake circuit. The power required to produce a pressure change. In this way, a high-power motor is required, and in addition to the higher cost, the high-power motor also occupies a larger volume and causes waste of energy. 3 · The problem of cutting the original brake pipe: If the locomotive is to be equipped with the brake device 1, the original brake pipe needs to be divided into two, and a section is connected by the brake device 4 to the oil inlet 1 in the brake device 1 2 3 A section is connected to the brake caliper 1 1 1 in the brake disc 1 1 through the oil outlet 1 2 4 in the brake device 1. Therefore, a new specification of the brake pipe is required to make the brake device installable. 1. Increase production costs. [New content] In view of this, the author of this case, considering the lack of existing hydraulic anti-lock brake system devices of locomotive, carefully considered and finally developed this creation "embedded locomotive hydraulic anti-lock brake system". This creation is an excellent design that uses a power motor to drive a hydraulic adjustment mechanism embedded in the disc brake of a locomotive, which can achieve fast, small size, and low energy consumption. In order to achieve the structural characteristics and technical means of the above purpose, the creation of "embedded locomotive hydraulic anti-lock brake system" includes a disc brake, a master cylinder, hydraulic adjustment mechanism, and a power unit that are already on the vehicle body. in

M275136 IV. Creation Instructions (5) In: The original brake oil pipe connecting the brake master cylinder and the disc brake was changed to connect the brake master cylinder and the hydraulic adjustment mechanism, and the hydraulic adjustment mechanism was directly embedded in the disc brake. The hydraulic adjustment mechanism is driven by a power motor, and a fail-safe circuit is established by using a solenoid valve, and the electric control unit is used to perform an anti-lock braking action. The hydraulic regulating mechanism has a main channel and a fail-safe channel. The main channel has a built-in pressure regulating valve shaft and is connected to the power motor through the screw control shaft. A fail-safe channel has a solenoid valve to control the opening and closing of the fail-safe channel. The electronic control unit controls the rotation of the power motor and the operation of the solenoid valve. With this design, when the wheel is about to lock up, the electric control unit drives the power motor and the solenoid valve at the same time, so that the power motor drives the spiral control shaft to drive the pressure regulating valve shaft to move, close the main channel, and make the solenoid valve actuate and close failure. The safe passage prevents the master cylinder from flowing into the disc brake brake oil, so that the amount of brake oil in the disc brake is fixed, and then the displacement of the pressure regulating valve shaft continues to increase to increase the volume in the disc brake. The pressure of the brake fluid in the disc brake achieves anti-locking brake action. And because of its simple structure, it is small in size and can be embedded in the disc brakes of locomotive, thereby speeding up the response frequency of brake modulation and reducing the energy consumption of the power unit, making the locomotive equipped with this device anti-lock brakes. efficacy. The reason is that I have a more detailed and clear understanding of the purpose, efficacy, and structural characteristics of this creation. I will give you a preferred embodiment of this creation with illustrations later.

Page 10 M275136 IV. Creation instructions (6) [Embodiment] First, please refer to the third figure, which is a schematic cross-sectional view of a preferred embodiment of this creation. As shown in the figure, the braking device of this embodiment 2, which includes a hydraulic brake mechanism 2 1 'brake caliper 2 1 1 which controls the movement of the brake caliper 2 2' power unit 2 3, and the brake 2 4; the liquid dust adjustment mechanism 22 includes an internal Main body 2 2 0 with main channel 221, a pressure regulating valve shaft 2 2 2 provided in main channel 2 2 1 of main body 2 2 0, a failure female full channel 223 'power unit provided in main body 2 2 0 side 2 3 is a screw control shaft 2 3 1 that can push the pressure regulating valve shaft 2 2 2, a power motor 2 3 2 that drives the movement of the screw control shaft 2 3 1, and a fail-safe channel 2 2 3 Solenoid valve 2 3 3,

An electric control unit that controls the power motor 2 3 2 rotation and controls the solenoid valve 2 3 3 opening and closing 2 3 4 'brake master cylinder 2 4 series includes a brake handle 2 4 1' for the driver of the locomotive to operate The oil supply brake cylinder 2 4 2 is a brake circuit 2 4 3 which connects the brake cylinder 2 4 2 and the hydraulic adjustment mechanism 2 2 to the main channel 2 2 1.

Continue to refer to the third figure, and cooperate with the fourth figure, which is a schematic diagram of a preferred embodiment of the creation. As shown in the figure, when the locomotive driver presses the brake handle 241, the brake oil is supplied by the master cylinder. The brake cylinder 242 of 24 flows into the main channel 2 2 of the hydraulic adjustment mechanism 2 2 through the brake pipe 2 4 3, and then directly 々, L is inserted into the brake caliper 2 1 of the disc brake 2 1 to make the brake caliper 2 1 1 pair of brake discs 2 1 2 generates frictional resistance to slow down the vehicle to complete the braking action; continued as shown in the fourth figure, when the electric control unit 234 of the power unit 23 senses that the wheels are about to lock up, the electric control The unit 2 3 4 then orders the power motor 2 3 2 to run, so that the power motor 2 3 2 drives the screw control shaft 2 3 1 to run, and pushes the pressure regulating valve shaft 222 in the hydraulic pressure regulating mechanism 22 to move in the main channel 221

M275136, using the displacement of the pressure regulating valve shaft 2 2 2 disc brakes 21 of the brake caliper 211 teaching 4 main 22 22 into the volume of the car sweet 2il 'lower the brake caliper m' and increase the brake at the same time The brake caliper 2 1 1 disengages from the brake disc, the brake oil is firm, and the friction resistance is generated, so that the wheel is locked by the second lock = disk 23 ^ ^ ^ ^ .t 2 34 ^, -i Λ'ο, € / Λ 2 34 will instruct the power motor 2 3 2 to move the Korean electric motor when the electric control unit 231 pushes against the liquid dust regulator and moves it to rotate 22; the motor 2 3 2 drives the spiral channel 221 to reduce the movement The nut shaft 2 2 2 is mainly used to increase the volume in the brake caliper 2 1 1 to increase the brake oil in: The pressure in the caliper 2 1 1 increases the frictional resistance of the brake caliper to the brake disc 2 1 2 To increase the resistance of the vehicle when braking. In this way, during the cycle of increasing the braking resistance and reducing the braking resistance, the cycle effect is repeated to achieve the braking effect of the locomotive ABS braking system. Continue to refer to the fourth figure. When the electric control unit 234 commands the power motor 23 2 to run, the electric control unit 2 34 also orders the solenoid valve 2 3 3 to close to close the fail-safe passage 2 2 3 and block the brake master cylinder 2 4 Passing the brake line 2 4 3 Continue to the fail-safe passage 2 2 3 into the brake fluid of the hydraulic regulating mechanism 2 2. When the power motor 2 3 2 fails and the main channel 2 2 1 in the hydraulic regulating mechanism 2 2 is closed and cannot be opened, the electric control unit 2 3 4 will stop closing the solenoid valve 2 3 3 to make the fail-safe channel 2 2 3 is turned on, so that the brake oil can flow into the brake caliper 2 1 1 through the fail-safe channel 2/3, so that the original braking function is not affected, and the driver and the driver can still perform the braking action, which makes this creation invalid. Wang Wenzhi's achievements can also be seen from the above description, this creation does have an increase in its efficacy

M275136 Creation Instructions (8), here are the following-one of the following descriptions: • Solve the problem of cutting the brake pipe: As this creation changes the traditional ABS method of cutting the brake pipe 2 4 3, directly adjust the hydraulic pressure The mechanism 2 2 is embedded in the disc brake 2 1, so this creation effectively reduces its production cost. 2 · Environmental protection and low energy consumption: The rear-entry design allows the power motor 2 3 2 to pass through the hydraulic adjustment mechanism 2 2 It is only necessary to adjust the volume pressure of the brake oil in the brake caliper 2 1 1, so the power motor 2 3 2 is greatly reduced. The required power can also complete its anti-lock braking action while consuming lower power energy, which is more environmentally friendly than the traditional design. 3 · Solve the problem of brake lever chattering: Since the hydraulic adjustment mechanism 2 2 is used to cut off the brake adjusting mechanism 2 2 1 in this creative action, the brake handle 2 4 1 will not be actuated by the power motor when the hydraulic adjustment mechanism 2 2 will The vibration of the brake pressure is transmitted back to the brake handle 2 4 1, which can effectively prevent the vibration problem caused by the change of the brake pressure.
