Abstract
The utility model relates to a brake arm and brake lining structure of a maglev brake. A brake arm and a brake lining are connected with each other through a pin roll. A pin hole is formed in the upper end of the brake arm. A pin hole is formed in the rear side of the brake lining. The pin hole in the brake arm and the pin hole in the rear side of the brake lining are connected through the pin roll. The brake lining is provided with a rotating seat. A pin hole is formed in the side surface of the rotating seat. The upper surface of the rotating seat is connected with a sintered plate base plate through bolts. The upper surface of the sintered plate base plate is connected with a copper-base alloy friction plate. Since the brake lining and the brake arm are of a pin-roll rotating structure, one rotation freedom degree is added, the brake lining is enabled to be in full contact with a track during braking and eccentric wear is not produced. Since the installation side surface of the brake arm is of a plane structure, on the premise that the brake arm has a freedom degree, the rotating angle of the brake arm is limited and the safe operation of equipment is guaranteed. Since the brake lining is of a two-part structure, the replaceability of the brake lining and the maintainability of the entire mechanism are guaranteed, and the service life of the entire mechanism is prolonged.
Description
Technical field
The utility model belongs to the rail locomotive brake member, particularly the floating break brake arm of a kind of magnetic and brake lining structure.
Background technique
The floating break of level type magnetic plays vital effect as the safe operation of magnetic suspension train, and brake lining forms as direct executive component, and its friction factor, working life, safety coefficient, maintenance and installation convenience are all determining the quality of solid stop performance.
The model utility content
Technical problem to be solved in the utility model is: the floating break brake arm of a kind of magnetic and brake lining structure are provided.Reach friction factor, working life, safety coefficient, the maintenance of brake lining composition and index request easily is installed.
The technical solution of the utility model is:
The floating break brake arm of a kind of magnetic and brake lining structure, it is characterized in that: brake arm connects by bearing pin with brake lining, and there is pin-and-hole the brake arm upper end, and pin-and-hole on the brake lining rear side is connected by bearing pin between the pin-and-hole on after the pin-and-hole on brake arm and brake lining.
Described brake lining has rotary seat, and there is pin-and-hole the rotary seat side, is bolted the sintered plate substrate above rotary seat, connects the copper base alloy friction plate above the sintered plate substrate.
The utility model effect is:
Adopt the bearing pin rotational structure between brake lining and brake arm, increase a rotary freedom, when guaranteeing braking, brake lining comprehensive engagement track, do not produce eccentric wear.Brake arm is installed the side and is adopted plane structure, guarantees it in the situation that there is degrees of freedom to limit again its angle of swing, guarantees the device security running.
For brake lining, be divided into two parts, wherein a part is rotary seat, another one is partly the sintered plate of copper base alloy friction plate and substrate, and is with bolts between two structures.Structure as shown above.Structure has guaranteed the convertibility of brake lining and the easy-maintenance of whole mechanism, and has extended the working life of whole mechanism.
Parameter
Brake lining friction factor 0.2-0.3 gets 0.2
Braking force 250kg * 2
The stainless steel-based back of the body of material, copper-base powder metallurgy matrix
1), the small sway up and down that realizes brake lining is with the tilt angle of reply track, prevents that it from the eccentric wear phenomenon occuring characteristics:.2), be convenient to safeguard, install.3), friction plate is convenient to change, save operating cost.

In figure: 1 brake arm, 2 brake linings, 3 bearing pins, 4 rotary seats, 5 copper base alloy friction plates, 6 sintered plate substrates, 7 bolts,
Embodiment
The floating break brake arm of a kind of magnetic and brake lining structure as shown in Figure 1, it is characterized in that: brake arm connects by bearing pin with brake lining, and there is pin-and-hole the brake arm upper end, and pin-and-hole on the brake lining rear side is connected by bearing pin between the pin-and-hole on after the pin-and-hole on brake arm and brake lining.
Brake lining as shown in Figure 2 has rotary seat, and there is pin-and-hole the rotary seat side, is bolted the sintered plate substrate above rotary seat, connects the copper base alloy friction plate above the sintered plate substrate.
Level type magnetic floats the break principle:
Adopt the bearing pin rotational structure between brake pad and brake arm, increase a rotary freedom, when guaranteeing braking, brake lining comprehensive engagement track, do not produce eccentric wear.
Brake arm is installed the side and is adopted plane structure, guarantees it in the situation that there is degrees of freedom to limit again its angle of swing, guarantees the device security running.
Brake arm and the rotatable angle of brake pad fitting seat are ± 14.5 °, by this angular range, can not realize due to the foozle of guide rail and break that face contacted when both can the friction compensation sheet contacting with guide rail, also limited simultaneously the limit position of brake pad rotation, guaranteed that brake pad can well contact with guide rail.
For brake lining, be divided into two parts, wherein a part is rotary seat, another one is partly the sintered plate of copper base alloy friction plate and substrate, and is with bolts between two structures.Structure as shown above.Structure has guaranteed the convertibility of brake lining and the easy-maintenance of whole mechanism, and has extended the working life of whole mechanism.
Claims (2)
