Problems solved by technology

However, in the structure described in Patent Document 1, the cover portion (31) protrudes only from the cylinder main body (13)
Therefore, when the cylinder main body (13) is arranged at a position inward from the side of the railway vehicle, etc., when the operator visually views the cover portion (31), the floor equipment becomes an obstacle, and it is difficult for the operator to visually confirm the cover portion ( 31) Location
Therefore, even if the cover part (13) is painted with a bright color, it is difficult to visually confirm the position of the cover part (13), thereby making it difficult to confirm whether the parking spring brake mechanism is working
In addition, in rainy weather, dusk, etc., it is difficult for light to enter the surroundings of the cover part (13), and it is even more difficult for the operator to visually confirm the position of the cover part (13).

Abstract

The invention provides a braking device for a vehicle, and the braking device enables the visual affirmation of the working state of a parking braking mechanism to be easier. The braking device (1) isprovided with a second piston (35) and a display unit (10). The second piston (35) is a piston for the braking of a parking spring and aims at the braking force generated during the parking of a railway vehicle. The display unit (10) is used for displaying the position of the second piston (35), and comprises a measuring member (71). The measuring member (71) can move relative to the second piston (35) and the top end part (70a) of a dustproof sleeve (70).

Description

[0001] This application is a divisional application of the application with the application number 201410107032.1, the application date is 2014-3-21, and the invention name is the brake device for vehicles. technical field [0002] The present invention relates to a vehicle brake device provided on vehicles such as railway vehicles. Background technique [0003] For example, a brake device provided with a parking spring brake mechanism is known as a brake device provided on a railway vehicle (for example, refer to Patent Document 1). The above-mentioned parking spring brake mechanism is used when a railway vehicle is parked. In addition, the parking spring brake mechanism is configured to be actuated by moving the parking piston pressurized by the urging force of the parking spring in a predetermined braking operation direction. [0004] In addition, the brake device disclosed in Patent Document 1 is provided with a structure that allows the operator to visually confirm whe...
