Description

Technical Field

[0001] The invention relates to an anti-skid railway vehicle brake caliper, in particular to an anti-skid railway vehicle brake caliper. Background Art

[0002] Railway vehicles are inevitably equipped with a braking system for performing braking. Various braking systems have been developed for the safety of passengers and cargo. Among them, the caliper brake is a braking system that contacts and pressurizes the brake pads on both sides of the brake disc that rotates with the wheel, thereby obtaining braking force through friction or clamping pressure between the brake disc and the brake pads. Such a caliper brake includes a caliper that surrounds the brake pad and allows the brake pad to move forward and backward toward the brake disc. The caliper has a cylinder and a piston, thereby applying hydraulic pressure for braking to the inside of the cylinder, so that the piston moves forward and pressurizes the brake pad toward the brake disc to achieve braking of the vehicle.

[0003] At present, there are still some defects and deficiencies in the use of railway vehicle brake calipers. The specific areas that need to be improved are as follows: Most existing railway vehicle brake calipers use two friction plates to press the brake disc against each other to brake the vehicle. The braking method is relatively simple, resulting in poor braking effect and long braking distance. Existing caliper brakes mainly rely on the friction force generated by the caliper clamping the friction plate and the brake disc to achieve vehicle braking. Due to the instability of the friction pair system, unstable vibration of the brake components is often caused during the braking process. When the vibration frequencies of different brake components are similar, resonance will occur, which will lead to the appearance of braking noise. The noise decibels are amplified through the resonance of the brake disc, affecting the riding experience of the driver and passengers. Existing railway vehicle brake calipers are not convenient for users to disassemble and maintain, resulting in complicated maintenance operations and low efficiency. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a first friction plate, a second friction plate and a third friction plate on the outer side of the brake disc at the same time. When braking a railway vehicle, hydraulic oil can be injected into the oil cylinder so that the hydraulic oil squeezes the piston disc to move forward. At this time, the piston disc drives the fixed rod, the fourth fixed plate and the second friction plate to move forward. When the second friction plate contacts the rear side of the brake disc, the continuous injection of hydraulic oil causes the oil cylinder, the mounting frame and the third friction plate to move backward, driving the third friction plate to contact the front side of the brake disc. At this time, the second friction plate and the third friction plate are used to clamp the brake disc to brake the vehicle. When the fixed rod moves forward, the fixed plate three and the wedge block are driven forward by the push plate. When the wedge block moves forward, it squeezes the first friction plate to move right, so that the first friction plate contacts the side of the brake disc, thereby further braking the brake disc, effectively improving the braking effect of the vehicle, shortening the braking distance of the vehicle, and also improving the anti-skid effect of the vehicle when braking and parking.

[0016] The present invention provides a fixing frame three on the left side of the mounting frame, and provides screws and a pressure plate to fix multiple mass blocks on the fixing frame three, so that the natural frequency of the mounting frame is changed by using the multiple mass blocks, so that the natural frequency of the mounting frame is different from the natural frequency of the multiple friction plates of the caliper, thereby effectively avoiding resonance between the brake caliper and other structures, thereby effectively avoiding resonance noise, or effectively reducing resonance noise, and at the same time, it is also convenient to adjust the number and position of the mass blocks, so that the natural frequency of the mounting frame is also adjusted accordingly, so that the brake caliper has more specifications of natural frequencies, and can be adjusted accordingly with the frequency changes caused by the wear of the first friction plate, the second friction plate and the third friction plate, and has a wide range of applications.

[0017] The present invention connects the third friction plate with the mounting frame by arranging a support frame, a third fixing ear seat and a fifth bolt, and connects the second friction plate with a fourth fixing plate by arranging a first fixing ear seat and a third bolt, so that after the second friction plate and the third friction plate are seriously worn, it is convenient for the user to disassemble and replace the second friction plate and the third friction plate, effectively ensuring the braking effect of the second friction plate and the third friction plate on the brake disc, and the disassembly and assembly are convenient and quick, and easy to maintain.

[0018] The present invention provides a plug box at the outer side of the oil cylinder, and a plug plate is provided on the connecting frame to be plugged into the plug box, and a screw hole three is opened on the connecting frame to be connected to the lead screw. When the oil cylinder needs to be maintained, the user can rotate the rotating shaft to use the bevel gear one and the bevel gear two to drive the lead screw to rotate forward. When the lead screw rotates forward, the two connecting frames are driven away from each other through the drop three to make the plug plate detach from the plug box. At this time, the user can pull the oil cylinder backward to move the oil cylinder to the outside of the mounting frame, so that the user can repair and maintain the oil cylinder, which further improves the convenience of maintenance of the device.

When braking the vehicle, hydraulic oil is injected into the oil cylinder 610 through the oil inlet pipe 630, so that the hydraulic oil pushes the piston disc 634 forward. At this time, the piston disc 634 drives the fixing rod 626, the fixing plate 4 623 and the second friction plate 611 to move forward. When the second friction plate 611 contacts the rear side of the brake disc 2, the continuous injection of hydraulic oil causes the oil cylinder 610, the mounting frame 5 and the third friction plate 18 to move backward, driving the third friction plate 18 to contact the front side of the brake disc 2. At this time, the second friction plate 611 and the third friction plate 18 are used to clamp the brake disc 2 to brake the vehicle. When the mounting frame 5 moves backward, the telescopic rod 1 614 and the spring 1 613 are stretched, so that the spring 1 613 generates tension. When the fixing rod 626 moves forward, the fixing plate 3 620 and the wedge block 619 are driven forward through the push plate 624. When the wedge block 619 moves forward, it squeezes the first friction plate 65 to move rightward, so that the first friction plate 65 contacts the side of the brake disc 2, thereby further braking the brake disc 2. When the wedge block 619 pushes the first friction plate 65 to move rightward, it stretches the telescopic rod 2 615 and the spring 2 616, so that the spring 2 616 generates a pulling force. When the vehicle brake is released, the hydraulic oil in the cylinder 610 is discharged through the oil inlet pipe 630. At this time, the tension of the multiple springs 1 613 is used to pull the mounting frame 5 to move so that the second friction plate 611 and the third friction plate 18 are separated from the brake disc 2. When the hydraulic oil is discharged from the cylinder 610, the piston plate 634 and the fixing rod 626 move backward so that the wedge block 619 gradually separates from the first friction plate 65. At this time, the tension of the spring 2 616 is used to pull the first friction plate 65 to move leftward and separate from the brake disc 2. When the second friction plate 611 and the third friction plate 18 need to be disassembled and replaced, the bolt five 20 and bolt three 622 can be rotated to disassemble the second friction plate 611 and the third friction plate 18. When the oil cylinder 610 needs to be maintained, the user can rotate the rotating shaft 68 and use the bevel gear one 628 and the bevel gear two 629 to drive the screw 69 to rotate forward. When the screw 69 rotates forward, it drives the two connecting frames 625 away from each other through the drop three so that the plug plate 632 is separated from the plug box 631. At this time, the user can pull the oil cylinder 610 backward to move the oil cylinder 610 to the outside of the mounting frame 5 for maintenance operations.
