7c and washer 3 inserted into the end of spring rod 28
It is further compressed against the restoring force between zero. Thus, the brake unit 20 is in an open state. At this time, when the limit switch 44 is operated by the dog 42, the open state of the brake unit 20 is electrically detected and used as a safety signal for driving the vehicle 1.

Next, if the speed of the vehicle 1 becomes higher than a predetermined driving speed due to an abnormality such as breakage or loosening of the rope 2 that pulls the vehicle 1, the rotation speed of the wheel 6 also increases, and the gear meshing with the gear 50 rotating together with the wheel 6 becomes excessive. The overspeed detector 52 operates with the gear 51 of the speed detector 52 to generate an overspeed signal, which is sent to the rotation direction determination means RD to determine the rotation direction, and the rotation direction signal is transmitted to the control unit CN together with the overspeed signal. Sent to Then, the control device CN excites the solenoid of the solenoid valve 60. Circuit 73 that was shut off when solenoid valve 60 was energized
Is opened and the pressure oil passes and branches at the connection point 82
From the tank 70. At the same time, the hydraulic pressure in the hydraulic cylinder 33 decreases, and the axial force acting on the piston rod 34 of the hydraulic cylinder 33 disappears.

As a result, the piston rod 34, the link rod 35 and the spring rod 28 are moved by arrows 99 and 101 by the restoring force of the disc spring set 29 compressed as shown in FIG.
The brake lever 22 on the right side of the drawing restrained by the link rod 35 with the lever pin 25 moves the pin 40 away from the stopper 41 of the lever block 21 to move the rod 2
The brake shoe 23 rotates in the direction of the arrow 103 around the axis 4, and the brake shoe 23 contacts the rail 3. At this time, the two guide shoes 26, 26 inserted into the lever pin 25 slide in the guide holes 27b, 27b formed in the guide plates 27a, 27a of the lever guide 27, respectively. at the same time,
The hydraulic cylinder 33 and the lever guide 27 move in the directions of arrows 97 and 98 in opposition to each other, and the left brake lever 22 on the left side shown in FIG.
The pin 40 is separated from the stopper 41 of the lever block 21 and rotates in the direction of the arrow 102 around the rod 24,
The brake shoe 23 comes into contact with the rail 3. Thus,
When the brake levers 22 and 22 bite the rail 3 from the left and right by the restoring force of the compressed disc spring set 29, the vehicle 1

The vehicle 1 has an axle frame 8 on which a wheel 6 rolling on a rail 3 is rotatably mounted on an axle 7 to improve the ride comfort of passengers.
45 and an elastic body 48 are interposed therebetween. Therefore, a displacement occurs in the interval between the bogie 4 and the rail 3 due to a load variation depending on the number of passengers or the riding position of the vehicle 1. In order to cope with this, as described above, the brake device 10 of the present invention connects the brake unit 20 to the brackets 4a,
The support 4a, the axle frame 8, the connecting rods 8, 8 and the brake frame 14 are supported by a parallel link mechanism that operates vertically. In addition, the pivot point constituting the parallel link mechanism is made to coincide with the axle 7 of the wheel 6. Therefore, the vertical distance between the brake unit 20 and the rail 3 is always kept parallel and constant without being affected by the load fluctuation of the vehicle body 1a. Further, the lever block 21 is also provided with guide rollers 39, 39 and guide rollers 39, 39 rolling on both side surfaces of the rail 3, so that the brake shoes 2 of the brake lavers 22, 22 located on the left and right sides of the rail 3 are provided.
Since the distance between the brake device 3 and 23 can be kept constant, the brake device 10 can exhibit a stable braking action. Further, a disc spring set 29 for applying a braking force to the opposing brake levers 22 and 22;
The hydraulic cylinder 33 for opening the brake levers 22 and 22 against the restoring force of the hydraulic cylinder 9 is arranged on the same axis and supported by the brake levers 22 and 22, so that the braking operation is smoother. Done in

[0027]

As described above, the vehicle brake device provided in the vehicle according to the present invention has a structure in which a brake unit that engages a rail with a bogie using a parallel link mechanism is suspended. The pivot point is located concentrically with the axle of the wheel rolling the rail. As a result, when a shock absorber or an elastic body is incorporated between the bogie and the wheels to improve the ride comfort of passengers,
Even if displacement occurs between the bogie and the rail due to load fluctuations due to the number of passengers and the riding position, the vertical positional relationship between the brake unit and the rail can be always kept constant and parallel. Further, the brake unit is provided with a guide roller which rotates on both sides of the rail in contact with the left and right sides, and a stable braking action is obtained by maintaining a constant horizontal distance between the brake lever and the rail.

A disc spring set for applying a braking force to the brake lever, and a hydraulic cylinder for releasing the brake lever from the braking position against the restoring force of the disc spring set are supported by the brake lever, and are coaxially mounted. By arranging, the mechanism is simplified and a smoother braking operation can be performed.

Further, the traveling direction of the vehicle is judged by judging the rotation of the wheel detected by the overspeed detector by the rotation direction judging means. For example, when the vehicle is running in the upward direction, the brake device is activated. By performing control not to operate the vehicle, it is possible to avoid injuries due to a fall of a passenger due to a sudden stop of the vehicle. Therefore, the present invention has an effect that it is possible to provide a vehicle brake device for a cable car with very excellent safety.
