Abstract
The utility model relates to a hydraulic disk brake device for a narrow-gauge electric locomotive and belongs to a brake device. The hydraulic disk brake device mainly solves the technical problem that the conventional pneumatic brake device is unstable and not reliable enough in brake. The technical scheme has the key point that the hydraulic disk brake device comprises a brake pedal plate (1) and brake disc s(4) and is characterized in that a set of brake discs (4) is arranged on two wheel shafts of the electric locomotive; brake branch pumps (3) are arranged on two sides of each brake disc (4); the brake branch pumps (3) are connected with a brake master pump (2); and the brake pedal plate (1) is arranged on the brake master pump (2). The hydraulic disk brake device can realize speed-reducing brake, continual brake and emergency brake according to different pedaling forces, is reliable in brake, is not influenced by power failure, and can be widely applied to various narrow-gauge electric locomotives.
Description
Technical field
The utility model relates to a kind of brake equipment, particularly a kind of hydraulic disk brake equipment that is used for narrow-gauge electric locomotive.
Background technology
The general compressed air brake technology that adopts of present existing narrow-gauge electric locomotive braking, its braking is not steady, and less reliable.
Summary of the invention
The purpose of the utility model provides a kind of narrow-gauge electric locomotive easy to use, dependable performance and uses the hydraulic disk brake equipment.
The utility model solves the technical scheme that its technical matters adopted: it comprises braking footrest 1 and brake disc 4; And on 2 axletrees of electric locomotive, install one and overlap brake disc 4; Cooperate installation brake cylinder 3 in the both sides of each brake disc 4; Each brake cylinder 3 is connected with master brake cylinder 2 respectively, and braking footrest 1 is installed on master brake cylinder 2.Said master brake cylinder 2 joins with brake cylinder 3 respectively through conduit under fluid pressure.Inside move toward one another matches with brake disc 4 brake piston of brake cylinder 3 in the both sides of brake disc 4.
The beneficial effect of the utility model is: it can realize brake snub, conventional brake, emergency braking with the difference that pin is stepped on strength, and braking is reliable, the influence that is not had a power failure.It can be widely used on the various narrow-gauge electric locomotives.
Description of drawings
Fig. 1 is the principle of work scheme drawing of the utility model.
Fig. 2 is the contour structures scheme drawing of the utility model.
Among the figure: 1-brake pedal, 2-master brake cylinder, 3-brake cylinder, 4-brake disc.
The specific embodiment
The utility model mainly comprises braking footrest 1 and brake disc 4; And on 2 axletrees of electric locomotive, install one and overlap brake disc 4; Cooperate installation brake cylinder 3 in the both sides of each brake disc 4; Each brake cylinder 3 is connected with master brake cylinder 2 respectively, and braking footrest 1 is installed on master brake cylinder 2.Said master brake cylinder 2 joins with brake cylinder 3 respectively through conduit under fluid pressure, and inside move toward one another matches with brake disc 4 brake piston of brake cylinder 3 in the both sides of brake disc 4.Consult Fig. 1 and Fig. 2.
When the palpus glancing impact, driver's pin is stepped on braking footrest 1, and braking footrest promotes master brake cylinder 2 work; Master brake cylinder promotes brake cylinder 3 work through conduit under fluid pressure; Promote the brake piston motion and be close to, thereby produce friction force, hinder the brake disc rotation with brake disc with brake disc is two-way; Thereby hinder the electric locomotive axle motions, promptly produce braking.The increase that braking force is stepped on strength with pin increases, and adds the strength that big foot is stepped on when braking force is not enough, and the difference of stepping on strength with pin can realize brake snub, conventional brake, emergency braking, and braking is reliable, the influence that is not had a power failure.
