Abstract
The utility model discloses a brake unit, particularly a meter-gage locomotive three-axle bogie brake unit, which comprises a brake seat arranged on a truss. A brake mechanism is mounted on the brake seat, two sides of the truss are in shaft coupling with corner-shaped crank arms, a link rod is in shaft coupling between the crank arms of the two sides, and each crank arm is in shaft coupling with a traction rod connected with a locomotive body. The utility model is characterized in that concave edges are arranged on the crank arms, and a side recess is disposed on the upper portion of the side edge of the brake seat. The meter-gage locomotive three-axle bogie brake unit has the advantages that as the concave edges are arranged on the crank arms, the crank arms do no interfere with other components when rotating, thereby being capable of rotating freely. Additionally, because the side recess is disposed on the upper portion of the side edge of the brake seat for mounting the brake mechanism, installation of other components is provided with space, and the installing position of the brake unit can be appropriately moved down, thereby not only ensuring reliable installation of the brake unit but also fully utilizing space positions, avoiding collision of the brake unit with a four-connecting rod traction device accrued in the locomotive running, and realizing the application of the brake unit on the meter-gage locomotive three-axle bogie.
Description
Technical field
The utility model relates to a kind of brake unit, particularly a kind of meter trailer car three axle truck brake unit.
Background technology
The brake unit of widespread use is to be one in the segment sets such as braking reservoir, lever system, brake-shoe adjuster, brake shoe in engine truck at present.Brake unit is propulsion source with the pressurized air, makes brake shoe act on wheel tread with suitable pressure by braking reservoir, leverage, realizes locomotive brake.Arrange that on rice trailer car three axle truck above-mentioned brake unit is very difficult.Because the brake unit volume is bigger, if it is arranged in the right traction electric machine side of wheel, brake unit is then interfered with motor and gear case; If it is arranged in non-traction electric machine side, the brake unit of tween drive shaft is then interfered with draw gear.As adopt the tween drive shaft motor oppositely to place or other draw gear structure, and even brake unit can be installed, axle is heavily shifted to be increased, and wheelbase strengthens, and the bogie truck lengthening causes locomotive general layout difficulty.Above reason has restricted the application of brake unit on rice trailer car three axle truck.
Summary of the invention
The purpose of this utility model provides that a kind of parts do not interfere each other, rice trailer car three axle truck brake unit easy for installation, overcomes the deficiencies in the prior art.
Rice trailer car three axle truck brake unit of the present utility model, it comprises the Brake Block 7 that is installed on the framework 1, stop mechanism 5 is installed on Brake Block 7, be connected with the connecting lever 6 of turning shape at the equal axle in the both sides of framework 1, axle is connected with trace between the connecting lever 6 of both sides, 6 of each connecting levers are connected with the draw bar 3 that joins with car body, it is characterized in that: described connecting lever 6 is provided with concave edge 8, and the side top of described Brake Block 7 is provided with side recessed 9.
Rice trailer car three axle truck brake unit of the present utility model, owing on connecting lever, be provided with concave edge, when rotating, connecting lever do not interfere with miscellaneous part, turn freely, it is recessed that the side top of the Brake Block of installation stop mechanism is provided with side, the space is provided for the installation of miscellaneous part, the brake unit installation site suitably can be moved down, both guaranteed that the brake unit installation was reliable, make full use of the locus again, avoid brake unit and four connecting rod draw geares when locomotive operation, to collide, realize the application of brake unit on rice trailer car three axle truck.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment;
Fig. 2 is a schematic top plan view shown in Figure 1;
Fig. 3 is the structural representation of connecting lever 6;
Fig. 4 is the structural representation of Brake Block 7;
Fig. 5 is that scheme drawing is looked on a left side shown in Figure 4.
The specific embodiment
As shown in Figure 1, 2: 1 is framework, is fixed with Brake Block 7 below framework 1, and stop mechanism 5 is installed on the Brake Block 7, and the brake shoe 4 in the stop mechanism 5 matches to 2 with wheel.Also axle is connected with connecting lever 6 in the both sides of framework 1, is connected with trace between the connecting lever 6 of both sides.Connecting lever 6 joins with an end of draw bar 3, and the other end and the car body of draw bar 3 join.
As shown in Figure 3: interfere for connecting lever 6 and the Brake Block 7 of avoiding draw bar 3 assemblings, connecting lever 6 has been made new shaped design, the side of connecting lever 6 has recessed to the inside side, and concave edge 8 is promptly arranged.When making it in utilization, rotate to the utmost point extreme position, still keep certain clearance with Brake Block 7.
The position of this brake unit moves to and is rotated down 8 ° position during installation.Brake shoe 4 upper ends and four connecting rod draw geares generation interference in the locomotive operation have been avoided after moving.But it is stressed too big to note moving down the excessive brake unit Brake Block 7 that will cause, brake shoe 4 and problems such as wheel contacts during locomotive operation.
Shown in Fig. 4,5:, cause the 7 stressed increasings of brake unit Brake Block because the brake unit position moves down.For guarantee its intensity and framework 1 and the intensity of its connecting portion and not with motion in draw gear produce interference, designed the Brake Block 7 of special shape, promptly a upper lateral part of Brake Block 7 has the side that concaves, and side recessed 9 is promptly arranged.Brake Block 7 is by being welded in seat board on framework 1 crossbeam and two side adapter plates and forming with the side plate of adapter plate bolt.Side recessed 9 adopts big round-corner transition, avoids producing stress concentration, and intensity significantly improves, and has also reduced seat and framework junction weld stress, and the corresponding change of bolt position as the case may be is as long as guarantee that stress point is best.
