Embodiment Construction

[0026] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0027] Such as figure 1 , figure 2 As shown, a high-efficiency braking electric car mainly includes a dual-circuit main braking system. There are two independent circuits. When any one of the circuits fails, it will not affect the normal operation of the other circuit, so as to ensure the reliability of braking. That is, the part of the service brake is set as a double-circuit structure.

[0028] Wherein, the vehicle body 100 is provided with a front axle brake 110 and a rear axle brake 120; in addition, a brake pedal is provided in the vehicle body 100, and the pedal lever mechanism can be controlled by stepping on the foot, thereby controlling the main braking system.

[0029] The brake master cylinder 200 is arrange...

Abstract

The invention provides an efficient braking tram which comprises a tram body internally provided with front axle brakes and rear axle brakes, a brake master cylinder arranged on the tram body, a frontbrake circuit connected with the brake master cylinder and the front axle brakes, and a rear brake circuit connected with the brake master cylinder and the rear axle brakes. The efficient braking tram has the beneficial effects that the tram is good in overall braking reliability and high in brake efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric cars and relates to an electric car with high-efficiency braking. Background technique [0002] The operating speed of trams is generally high, and in order to ensure driving safety, the braking system of locomotives is particularly important. Among them, the brake control unit is the core component of the brake system. When the locomotive encounters an emergency, the brake control unit immediately activates the brake mechanism, and completes the braking of the wheels by controlling the brake cylinder and other methods. Therefore, the stable and reliable operation of the brake control unit is directly related to the stability of the brake system, and its reliability is of great significance to the safety of rolling stock. [0003] For example, a Chinese patent with an application number of 201610004508.8 discloses a vibration damping device for a locomotive brake system, including a mounting fra...
