Description

Technical Field

[0001] This application relates to the technical field of brake cylinder hanger mechanisms, and particularly to a brake cylinder hanger mechanism device. Background Art

[0002] The brake caliper unit, as the final actuator for the parking and parking of rail transit vehicles, is related to public traffic safety. The brake caliper unit mainly consists of three parts: a brake cylinder, a caliper mechanism, and a hanger mechanism. The brake cylinder is mainly a device for generating braking force. The caliper mechanism is a force amplification mechanism of the brake cylinder. The hanger mechanism is a mechanism device that installs the brake cylinder and the caliper mechanism to the vehicle bogie and transmits the frictional force of the brake pads during braking to the bogie.

[0003] The hanger mechanisms used in previous brake caliper units mainly had the following two structural forms.

[0004] The first one: It is installed on the bogie in the form of a three-point suspension, that is, the brake pad holders on both sides of the brake disc are connected to the bogie by a fixed fork body, and the rubber joints on the cross frame body are connected to the bogie. The fixed fork body transmits the frictional force generated during braking. The rubber joints on the cross frame body have a certain stiffness and elasticity, which can adapt to the longitudinal movement, impact of the wheelset during vehicle driving braking, and the vibration in the up and down direction between the wheelset and the frame support. At the same time, the rubber joints have stiffness, which can suppress the free swing of the brake cylinder and the caliper. However, the rubber joints are exposed under the vehicle underframe, and are easily aged under high temperature and ozone environmental conditions, with a short service life. Generally, after 6 years of use, the service life is reached, and the entire brake caliper unit needs to be removed from the vehicle for replacement, which is time-consuming and laborious. Especially for vehicles equipped with a hydraulic braking system, it will inevitably be eroded by hydraulic oil, accelerating the aging.

[0005] The second one: It is installed on the bogie in the form of a four-point suspension, that is, mounting seat shaft holes are provided on the brake cylinder, and the brake cylinder is connected to the hanger through a rotating shaft, and the brake cylinder can rotate around the rotating shaft. At the same time, a pressure plate is provided on the brake cylinder. The pressure plate has elasticity and stiffness, which can adapt to the longitudinal movement of the wheelset during vehicle driving braking. When the wheelset moves longitudinally, it presses on the brake pad holder, drives the brake pad caliper mechanism, and drives the brake cylinder to yaw. During the yawing process of the brake cylinder, it presses on the pressure plate to rotate. At the same time, when not braking, it can suppress the free sway of the brake cylinder. This structure is simple, but there is no protective device for the contact between the pressure plate and the mounting bracket. During long-term use, dust and impurities will fall between the pressure plate and the mounting bracket, resulting in inconsistent compression amounts on both sides of the pressure plate, and the brake cylinder and the brake pads are skewed. Summary of the Invention

[0051] A floating bolt assembly 9, a cross frame body 10, a mounting seat 5 with a rotating shaft, and a mounting seat 12.

[0052] Among them, as Figures 9 to 13 shown, the floating bolt assembly 9 includes a bolt pin 91, a hexagonal bolt sleeve 92, a disc spring 93, and a flange sleeve 94; among them, the limit position of the compression of the disc spring 93 of the floating bolt assembly 9 restricts the maximum angle of the overall swing of the brake cylinder 3, the cross frame body 10, the brake pad support 2, and the lever arm 16.

[0054] The bolt pin 91 has a first flange surface 911 at its end face, a large cylindrical surface 912 at one end of the bolt pin 91.

[0058] As Figure 6 shown, the cross frame body 10 includes an I-shaped frame body and a cylinder body installed on the I-shaped frame body. The cylinder body has a first inner hole 101 of the cross frame body communicating with both ends of the cylinder body. Two oppositely arranged mounting seat components are respectively hermetically connected to both ends of the first inner hole 101 of the cross frame body. Each mounting seat component includes a mounting shaft. One end of the mounting shaft is hermetically connected to the first inner hole 101 of the cross frame body;

[0059] Two floating bolt assemblies 9 with pre-tightening force. Oppositely arranged on the side surface of the cylinder body are two second inner holes of the cross frame body communicating with the first inner hole 101 of the cross frame body. The two floating bolt assemblies 9 are respectively installed on the two second inner holes of the cross frame body. During the vehicle running, the squeezing force generated by the axle yaw is absorbed by the floating bolt assemblies 9 to limit the swing of the cross frame body 10.

[0060] The mounting shaft includes a first flange sleeve 71 and a second flange sleeve 72. The cross frame body 10 is connected to the rotatable shaft mounting seat 5 through the first flange sleeve 71. The cross frame body 10 rotates around the rotatable shaft mounting seat 5. The first flange sleeve 71 includes an O-ring seal groove. The sealing ring 8 is placed in the O-ring seal groove. After the first sleeve 61 is installed in the first flange sleeve 71, it is connected to the rotatable shaft mounting seat 5; wherein, the gasket 11 is installed on the cross frame body 10 through the screw 14.

[0062] Embodiment 2

[0063] This embodiment also provides a specific implementation manner of a brake cylinder hanger mechanism device.

[0064] The hanger device is installed on the bogie 1 and fixed by bolts to form an integral body. Under the conditions of curves, vibration and shock, the axle moves back and forth along the axle direction.

[0065] During braking, the brake pads clamp the brake disc, and the brake pads and the brake lever will swing along the swinging direction of the axle with the axle. At this time, the force of the axle swing is transmitted from the connecting hole of the lever arm 16 and the cross frame body 10 to the cross frame body 10. The hanger structure 4 rotates around the rotating shaft part of the rotating shaft mounting seat 5. The floating bolt assembly 9 installed on the cross frame body 10 will further compress the disc spring 93 under the action of force, so that the clamp can adapt to the axial movement of the axle.

[0066] When not braking, the gap between the brake pads and the brake disc is very small. When the axial movement of the axle is large, the brake disc squeezes the brake pads to repeat the above process. Similarly, the floating bolt assembly 9 can absorb the extrusion force generated by the axle yaw transmitted, and only generate a small amount of virtual contact force between the disc and the pads, avoiding the braking effect generated by the vehicle.

[0067] During the driving of the vehicle, a pre-tightening force is provided by the floating bolt assembly installed on the cross frame body 10 and acts on the rotating shaft part of the rotating shaft mounting seat 5. In the free state, it can prevent the entire brake clamp mechanism from swinging, making the structure more stable.

[0068] In summary, the present invention relates to a brake cylinder hanger mechanism device. As the base of the brake clamp actuator, the present invention realizes the reliable installation of the brake clamp mechanism on the bogie of the rail vehicle. During the driving of the vehicle, the present invention can adapt to the axial movement and yaw of the wheel set during braking, and at the same time, prevent the free swing of the brake clamp actuator under vibration and shock during the driving of the vehicle.

[0069] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the protection scope of the appended claims.
