Embodiment Construction

[0010] like figure 1 The shown lever-type magnetic suspension brake includes a rubber spring, an outer lever device, a brake pad, an inner lever device, a hydraulic cylinder, and a pole plate. The lever-type magnetic suspension brake is a pincer-shaped structure composed of an outer lever device and an inner lever device. There is a rubber spring between the axle frame and the pole plate. The upper ends of the outer lever device and the inner lever device are connected to the brake pads by pin shafts on the inner surface opposite to the upper end of the outer lever device. sides of the cylinder.

Abstract

The invention discloses a lever type magnetic suspension brake. The middle parts of an outside lever device and an inside lever device are respectively connected at two sides of a pole plate through respective middle shaft and respective shaft bracket; a rubber spring is arranged between each of the two shaft brackets and the pole plate; the opposite inner side surfaces of the upper ends of the outside lever device and the inside lever device are respectively connected with a brake pad through a pin shaft; and the lower ends of the outside lever device and the inside lever device are respectively connected at two sides of a hydraulic cylinder through a connecting shaft. A plier-type brake structure is adopted by the lever type magnetic suspension brake, and the hydraulic cylinder is used as a brake force generating unit and controlled by a brake control loop such as brake valves, wherein a brake arm at the inner side of the brake is of a small bending radius structure and therefore the installation of the brake arm at the inner side is facilitated. The ultimate displacement of the brake arm is plus or minus 10mm; and the inclined angle of a track can be protected against eccentric wear through the slight up and down swinging of the brake pad, thus good tightness is obtained and maintenance and installation are facilitated; and friction plates can be conveniently dismantled to replace and the operation cost is saved.

Description

technical field [0001] The invention belongs to rail locomotive brakes, in particular to a lever type magnetic suspension brake. Background technique [0002] As the running part of the maglev train, the maglev brake plays a vital role in the safe operation of the train. The existing brake has a complex structure and is inconvenient to install and maintain. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lever type magnetic suspension brake. [0004] The technical scheme of the present invention is: [0005] A lever-type magnetic levitation brake, characterized in that: a pincer-shaped structure composed of an outer lever device and an inner lever device, the middle parts of the outer lever device and the inner lever device are respectively connected to the pole plate by their respective intermediate shafts and shaft brackets. On both sides, there is a rubber spring between the two shaft frames and the pole p...
