Referring to fig. 1-4 in combination, the present embodiment provides a brake 100, and accordingly, a passenger car brake system (not shown).

The passenger cablecar brake system comprises the brake 100 and also comprises a hydraulic system (not shown) communicated with the oil cylinder 130 of the brake 100, and hydraulic oil is filled into or discharged from the oil cylinder 130 through the hydraulic system to adjust acting force applied by the oil cylinder 130 so as to realize switching of the braking state.

The brake 100 includes a bracket 110, a sliding sleeve 120, a friction disc 150, a cylinder 130, and a disc spring 160. The sliding sleeve 120 is slidably disposed on the support 110, and the friction disc 150 is fixedly coupled to the sliding sleeve 120, such that the friction disc 150 moves with the sliding sleeve 120 relative to the support 110. The oil cylinder 130 is disposed at one end of the sliding sleeve 120 far from the friction disc 150, and a pulling force directed from the friction disc 150 to the oil cylinder 130 is applied to the sliding sleeve 120 through the oil cylinder 130, because the oil cylinder 130 and the friction disc 150 are respectively located at two ends of the sliding sleeve 120, hydraulic oil leaked from the oil cylinder 130 does not flow to the friction disc 150, and the friction braking performance of the friction disc 150 is ensured. Meanwhile, the cylinder 130 comprises a cylinder sleeve 131 and a piston 132, the cylinder sleeve 131 is movably connected with the bracket 110, and the pre-pressure of the disc spring 160 is adjusted through the movement of the cylinder sleeve 131 relative to the bracket 110, so that the braking force of the brake 100 can meet the requirement, and the braking effect of the brake 100 can be further ensured.

The brake 100 provided in the present embodiment is further explained below:

referring to fig. 1-4, in the present embodiment, the sliding sleeve 120 is a cylindrical structure, and one end of the sliding sleeve is provided with a disk-shaped mounting flange 123 for mounting the friction disk 150. The sliding sleeve 120 has an annular accommodating cavity therein for accommodating the annular disc spring 160, and an end of the accommodating cavity away from the mounting flange 123 forms an opening. Accordingly, the sliding sleeve 120 has a connecting rod 122 for defining an inner circumference of the receiving chamber, and the connection of the sliding sleeve 120 with the piston 132 of the cylinder 130 is achieved by the connecting rod 122, i.e., the cylinder 130 and the friction disk 150 are at both axial ends of the sliding sleeve 120.

Specifically, the friction disc 150 is fixedly connected to the mounting flange 123 by a screw, and meanwhile, a through bolt hole is formed in the piston 132, and a bolt is screwed with the connecting rod 122 of the sliding sleeve 120 through the bolt hole, so that the piston 132 and the connecting rod 122 are connected into a whole, and the sliding sleeve 120 and the friction disc 150 on the sliding sleeve 120 are driven to move along with the piston 132.

In this embodiment, the head 132 of the piston 132 is disposed in the cylinder sleeve 131, and the piston rod of the piston 132 passes through the cylinder sleeve 131 and extends toward the friction disk 150, and is fixedly connected to the connecting rod 122 of the sliding sleeve 120. The portion of the space in the cylinder sleeve 131, which is located on the side of the piston 132 close to the friction disc 150, is an oil chamber 133, an oil inlet 134 and an oil passage 135 communicating the oil inlet 134 with the oil chamber 133 are provided on the cylinder sleeve 131, when hydraulic oil flows into the oil chamber 133 through the oil inlet 134 and the oil passage 135, the oil pressure in the oil chamber 133 increases, and the oil chamber 133 has an increasing tendency, so that the piston 132 is driven to move in a direction away from the friction disc 150, and the friction disc 150 is driven to move in a direction away from a member to be braked (not shown in the figure).

Accordingly, in the process that the sliding sleeve 120 moves away from the friction disc 150 under the driving of the piston 132, the disc spring 160 is pressed by the sliding sleeve 120, so as to apply a thrust force from the oil cylinder 130 to the friction disc 150 to the sliding sleeve 120, and further, under the condition that the thrust force is greater than the hydraulic pressure, the sliding sleeve 120 moves away from the oil cylinder 130 under the action of the disc spring 160, and further, the friction disc 150 is driven to move towards the direction close to the to-be-braked member.

In order to ensure the hydraulic stability and avoid the leakage of hydraulic oil, a first sealing element is arranged on the head of the piston 132 to seal the gap between the head of the piston 132 and the cylinder sleeve 131, and a second sealing element is arranged on the cylinder sleeve 131 to close the gap between the cylinder sleeve 131 and the piston rod, so that the sealing performance is maintained through the second sealing element under the condition that the piston rod slides relative to the cylinder sleeve 131.

Further, the cylinder 130 further includes a gasket 137 disposed outside the piston rod, and the gasket 137 is located inside the oil chamber 133 and between the head of the piston 132 and the cylinder sleeve 131.

Specifically, the positioning element 111 is a bolt structure screwed to the bracket 110, and an end of the positioning element 111 protrudes out of an end surface of the bracket 110, and the sliding sleeve 120 is limited by abutting against the sliding sleeve 120. Further, a key 124 is arranged on the sliding sleeve 120, and the circumferential relative position between the sliding sleeve 120 and the support 110 is limited through the matching of the key 124 and the support 110, so that the rotation of the friction disc 150 in the braking process is avoided.

Further, the brake 100 further comprises a pressing cover 145, wherein the pressing cover 145 is disposed between the disc spring 160 and the cylinder sleeve 131, and one end of the pressing cover 145 extends into the mounting cavity 121 of the sliding sleeve 120 and abuts against the disc spring 160, so as to ensure a pressing force between the cylinder sleeve 131 and the disc spring 160.

Referring to fig. 1 to 4, in the present embodiment, the brake 100 further includes an adjusting screw 141, the adjusting screw 141 is screwed with the bracket 110, and the cylinder sleeve 131 is provided with a boss 136 abutting against the adjusting screw 141, the cylinder sleeve 131 is pushed by the adjusting screw 141 to move toward the friction disc 150, and the disc spring 160 is pressed, so as to adjust the pre-pressure of the disc spring 160.

Specifically, the adjusting screw 141 is an annular screw structure having an external thread, which is sleeved outside the cylinder sleeve 131, and is screwed with the bracket 110 through the external thread, and under the condition that the adjusting screw 141 rotates, the adjusting screw 141 moves relative to the bracket 110 along the axial direction. The cylinder sleeve 131 is provided with a boss 136 at one side of the adjusting screw 141 close to the friction disc 150, and the boss 136 is abutted against the adjusting screw 141, so that when the adjusting screw 141 moves relative to the bracket 110 in a direction close to the friction disc 150, the cylinder sleeve 131 can be pushed to move in a direction close to the friction disc 150, and the disc spring 160 is further pressed, so that the pre-pressure of the disc spring 160 is increased. Accordingly, when the adjusting screw 141 moves away from the friction disc 150 relative to the bracket 110, the cylinder sleeve 131 moves away from the friction disc 150 by the elastic force of the disc spring 160, and the pre-pressure of the disc spring 160 decreases.

Further, the brake 100 further includes a nut 143 screwed to the cylinder sleeve 131, and the nut 143 abuts against a side of the adjusting screw 141 away from the boss 136, that is, the adjusting screw 141 is clamped between the nut 143 and the boss 136. Specifically, the nut 143 is provided with a plurality of second notches 144, the plurality of second notches 144 are distributed at intervals along the circumferential direction of the nut 143, the adjusting screw 141 is provided with a plurality of first notches 142, the plurality of first notches 142 and the plurality of second notches 144 are arranged in a one-to-one correspondence manner, and thus the operating element is simultaneously matched with the first notches 142 and the second notches 144 to drive the adjusting bolt to rotate synchronously with the nut 143.

In this embodiment, the brake 100 further includes a pressure sensor 146, and the pressure sensor 146 is disposed at one side of the disc spring 160 and is used for detecting an elastic force generated by the disc spring 160. Specifically, the pressure sensor 146 is disposed at the bottom of the mounting cavity 121, i.e., at an end of the mounting cavity 121 close to the friction disc 150. One end of the disc spring 160 close to the friction disc 150 abuts against the pressure sensor 146, so that the elastic force of the disc spring 160 acting on the pressure sensor 146 can be detected by the pressure sensor 146. Optionally, the mounting flange 123 of the sliding sleeve 120 is provided with a hole 125 communicating with the mounting position of the pressure sensor 146, and the mounting position of the pressure sensor 146 is communicated with the outside through the hole 125. Through the detection of the elastic force of the disc spring 160, the pre-pressure of the disc spring 160 can be effectively ensured to be kept reliable, and the disc spring 160 is ensured to be in an effective use state.

It should be noted that the structure of the pressure sensor 146 is not limited here, and it should be understood that in other embodiments, the pressure sensor 146 may be provided as needed to detect the elastic force of the disc spring 160.

In this embodiment, the brake 100 further includes a distance sensor 147, the distance sensor 147 is used for detecting the positions of the support 110 and the sliding sleeve 120 in the axial direction of the oil cylinder 130, and the change in the distance between the support 110 and the sliding sleeve 120 during the braking operation can be obtained through the detection data of the distance sensor 147, so as to implement online real-time monitoring of the wear and the open gap of the friction disc 150.

Specifically, the distance sensor 147 is a laser displacement sensor, which is fixedly connected to the bracket 110 and is disposed toward the mounting flange 123 of the sliding sleeve 120, so that the position change data of the bracket 110 and the sliding sleeve 120 can be obtained through the distance between the laser displacement sensor and the mounting flange 123. The amount of wear of the friction disk 150 can be obtained by comparing the opening gap when the friction disk 150 is braked with a preset opening gap. The predetermined opening gap is a brake opening gap of the friction disc 150 when the friction disc 150 is not worn.

The pressure sensor 146 and the distance sensor 147 are electrically connected to a controller of the cable car brake system for transmitting detected signals to the controller, and the controller is also electrically connected to electrical components such as a solenoid valve in the hydraulic system. Therefore, the controller can detect the braking performance of the brake 100 and give an alarm or give an early warning according to the signals detected by the pressure sensor 146 and the distance sensor 147, and can perform PID (proportion integration differentiation) adjustment on the braking deceleration of the brake 100 through calculation, so that the control requirement of a cable car running at high altitude is met, the dynamic force (inertial force) is reduced or the development in the dynamic state is controlled, and the configuration of a traction cable is reduced.
