Abstract
The invention discloses a steering bogie brake device with a flexible fulcrum and belongs to the field of rail wagon machinery. The steering bogie brake device comprises a fixed lever fulcrum seat, a fixed lever, a brake beam, a floating lever, a fixed lever fulcrum, a chain shoe ring and a connecting element, wherein the fixed lever fulcrum seat and the fixed lever are connected through the connecting element, the chain shoe ring and the lever fulcrum. The steering bogie brake device has the advantages that the brake lever system torsion (tensioning force) caused by the vertical movement of a swing bolster is avoided, phenomena of single-side wheel tread scratching and abnormal wear of wheel pair single-side wheel edges because a shoe block deflects to the wheel edges are eliminated, the brake multiplying power and the brake efficiency of a steering bogie brake system are unchanged, other structures of a steering bogie do not need to be changed, and the reformation of the steering bogie is favorably realized. The steering bogie brake device is applicable to a single-side shoe block lower pull rod type basic brake device used on a wagon steering bogie.
Description
Affiliated technical field
The present invention relates to railway goods train bogie, especially the bogie truck brake equipment belongs to the railway truck field of mechanical technique.
Background technology
At present, the three-major-items roller bearing adapter stabilizer bar generally adopts the single brake shoe brake equipment, and it is by a floating lever, two brake beams, a pull bar; A truck dead lever; A dead lever fulcrum and the lever system that the dead lever fulcrum seat constitutes, brake beam is installed in the bogie side frame chute, can only be along the chute center line movement; The dead lever fulcrum seat is fixedly installed on the bolster, with its catenary motion.During car brakeing; Braking force puts on floating lever through the braking tie rod that is installed on the car body; Floating lever drives a brake beam, and to rely on trailing wheel right, and also to rely on front-wheel for another brake beam brake-force transmission through tie rod right for floating lever simultaneously, brake shoe on the brake beam is pressed in produces friction brake force on the wheel; Braking force is through passing to truck dead lever simultaneously, and dead lever fulcrum is delivered to the balance of the system that obtains on the dead lever fulcrum seat.Position by pull bar is different, pull bar and lower link system during this leverage is divided into, and middle tie system transmits pulling force at the glancing impact dead lever fulcrum, and the lower link system then transmits pressure.
Existing three-major-items roller bearing adapter stabilizer bar lower link foundation brake rigging adopts dead lever fulcrum one end to be connected with the dead lever fulcrum seat, and the other end is connected with truck dead lever.Through the connection of dead lever fulcrum, usually the dead lever fulcrum seat, dead lever fulcrum should be in the same plane that becomes 40 °～55 ° of angles with horizontal surface with truck dead lever.Because the variation of vehicle load, the truck bolster spring is compressed under the effect of load on spring, and dead lever fulcrum seat, dead lever fulcrum are along with bolster moves down together.Because brake beam is to be seated in the chute of bogie side frame through slide block (or Roller Shaft), bogie side frame can vertically not move down, and its position is fixed in vertical direction, and the position of truck dead lever just immobilizes like this.Because dead lever fulcrum seat, dead lever fulcrum and truck dead lever are rigidity; In the process that bolster moves down, brake beam at first can move to brake shoe and touch wheel rim to truck dead lever bevelled one side shifting; Then brake beam may continue to move; Brake shoe is squeezed into wheel rim, causes inhomogeneous to the wheel application force of one-sided wheeling edge wearing and brake beam two brake shoes, causes abnormal wear and the one-sided wheel tread flat of wheel to one-sided wheel rim.Simultaneously; All adopt cylindrical pin to connect because the braking leverage connects, can only with the plane of 40～55 ° of horizontal plane angles in move, therefore; During car brakeing; Produce torsion (being commonly called as " other strength ") between dead lever fulcrum seat, dead lever fulcrum, truck dead lever and the brake beam in the brake equipment, cause part accessory stress to increase, increase the crackle tendency.
In a word, lower link bogie truck braking leverage can only unavoidably bring the inside torsion of brake beam 6 cross travels and leverage at the level of incline in-plane moving when changing in dead lever fulcrum seat vertical position.
Summary of the invention
To the problems referred to above, the present invention provides a kind of bogie truck brake equipment that can in different plane, transmit braking force.
The technical solution adopted for the present invention to solve the technical problems is: the bogie truck brake equipment of band flexible point comprises dead lever fulcrum seat, truck dead lever, brake beam and floating lever; Also comprise dead lever fulcrum, chain hoof ring and attaching parts, be connected with chain hoof ring and balance pivot through attaching parts between dead lever fulcrum seat and the truck dead lever.
The invention has the beneficial effects as follows, avoided the braking leverage torsion (other strength) that causes owing to because of the bolster catenary motion; The wheel of having eliminated brake shoe deflection wheel rim and having caused is to the phenomenon of the abnormal wear and the one-sided wheel tread flat of one-sided wheel rim; The leverage ratio and the brake efficiency of bogie truck brake system are constant, and other structures of bogie truck need not to change, and help the transformation of bogie truck.Be applicable to the drop-down rod-type foundation brake rigging of the single brake shoe that uses on the roller bearing adapter stabilizer bar.

Fig. 2 is balance pivot 1 among Fig. 1, chain hoof ring 2 and attaching parts 3 structural representations;
Fig. 3 is balance pivot 1 among Fig. 1, chain hoof ring 2 and attaching parts 3 decomposition texture scheme drawings.
Parts and numbering among the figure:
The 1-dead lever fulcrum, 2-chain hoof ring, 3-attaching parts, 4-dead lever fulcrum seat, 5-truck dead lever, 6-brake beam, 7-floating lever.
The specific embodiment
Below in conjunction with embodiment the present invention is further specified.
Referring to Fig. 1,2, the bogie truck brake equipment of band flexible point comprises dead lever fulcrum seat 4, truck dead lever 5, brake beam 6 and floating lever 7; Also comprise dead lever fulcrum 1, chain hoof ring 2 and attaching parts 3, be connected with chain hoof ring 2 and balance pivot 1 through attaching parts 3 between dead lever fulcrum seat 4 and the truck dead lever 5.
Between dead lever fulcrum seat 4 and dead lever fulcrum 1, increase flexible point, increased the rotational freedom of dead lever fulcrum 1 with respect to dead lever fulcrum seat 4.For the lower link brake system, the glancing impact flexible point can bear pressure, allows dead lever fulcrum 1 bonded assembly two ends in Different Plane, to rotate, and can transmit compression brake power at glancing impact.
Attaching parts 3 is bolt or rivet.
Pin-and-hole edge between chain hoof ring 2 and dead lever fulcrum seat 4 and the dead lever fulcrum 1 adopts arc transition, helps the yaw motion of bolt or rivet.
Because the effect of flexible point can be or not same plane between dead lever fulcrum seat 4 and the truck dead lever 5; Avoided forcing the cross travel of brake beam 6 generations because of the bolster catenary motion; Eliminated because of dead lever fulcrum seat 4 catenary motions and forced the inside torsion between cross travel that brake beam 6 produces and truck dead lever 5, the floating lever 7; The wheel that has slowed down brake shoe deflection wheel rim and caused is to the abnormal wear of one-sided wheel rim, and avoids occurring the phenomenon of one-sided wheel tread flat.
