Abstract
The utility model relates to a slide block type channel steel brake beam comprising a channel steel brake beam frame and brake shoe holders. The slide block type channel steel brake beam is characterized in that each brake shoe holder is of a slide block type and each of two ends of the channel steel brake beam frame is provided with one brake shoe holder. The slide block type channel steel brake beam has the advantages of being high in strength, low in abrasion loss and long in service life, saving materials, prolonging the service life of accessories, reducing the overhaul cost, easily realizing production line operation and mechanized assembly, and remarkably improving the braking property, the running quality and the running stability of vehicles.
Description
Technical field:
The utility model relates to a kind of slide block type channel-section steel brake beam, belongs to the brake equipment field of components.
Background technology:
Brake beam is the railway truck running part---the critical component in the truck brake rigging device.The effect of foundation brake rigging is that to pass to wheel after the application force of brake cylinder is amplified right.When train braking, the application force of brake cylinder is through the brake lever on car body brake lever, top rod and the bogie truck down, with brake beam together with the brake shoe wheel that reclines, the prevention wheel, thus car retardation is moved up to stopping.In the train braking process, brake beam will bear brake cylinder output and the load after each lever transmission enlarges, and makes brake shoe be close to wheel tread again, so its performance all plays crucial effects to the deceleration and stopping performance and even the traffic safety of railway truck.
From 1966 since ministerial level identify to promote is produced, existing about more than 50 ten thousand liang of railway trucks dress is with the arc brake beam of chute-type, account for roller bearing adapter stabilizer bar with brake beam total about 65%.The arc brake beam of chute-type becomes brake beam frame by arc channel-section steel with the pillar assembly welding; The brake beam frame two ends brake head that is welded; Special hole is arranged in order to the Roller Shaft that is welded on each brake head; Its structure is simple relatively, has overcome shortcomings such as suspension type brake beam part is many in the past, brake beam is prone to come off, and has and makes simply, overhauls advantages such as convenient and safe in operation.
But through for many years production, utilization and maintenance practice, the arc brake beam of chute-type also exposes some problems, mainly contain following some:
1. the Roller Shaft at the arc brake beam of chute-type two ends is inserted in the chute of left and right sides frame, and the bogie side frame chute becomes certain leaning angle with horizontal surface, and the brake beam power of relying on for support was restored when train braking was alleviated.Because brake beam self can rotate around Roller Shaft, the counter torque that bogie side frame can not provide a restriction brake beam to rotate makes brake beam keep balance, and promptly Roller Shaft center and brake beam center of gravity depart from, and the brake shoe upper end is prone to ride on the wheel tread, is prone to cause brake shoe partial wear;
2. the arc brake beam of chute-type is a welded structure; The stressed position of concentrating is prone to crack, and especially the rigging position of brake head and brake beam frame needs to consider to reserve the assembly welding gap; Have easily to produce weld defect and the torsional deflection that welding causes, cause the brake beam undercapacity;
3. Roller Shaft is prone to produce the postwelding defective owing to be to adopt medium-carbon steel to add welding, causes Roller Shaft to fracture.
Summary of the invention:
The purpose of the utility model is for the deceleration and stopping performance that improves the truck brake rigging device, operation stability and safety, solves problems such as brake shoe partial wear, undercapacity and Roller Shaft in the arc brake beam utilization of chute-type fractures a kind of slide block type channel-section steel brake beam is provided.
The purpose of the utility model realizes in the following manner:
The utility model comprises channel-section steel brake beam frame, brake head, it is characterized in that: brake head is the slide block type brake head, at channel-section steel brake beam frame two ends a brake head is installed respectively.
Said slide block type brake head is on the end face of brake shoe base body, to have square mounting hole, and on the end face of brake shoe base body, to be provided with the cross section be hexagonal slide block.
At slide block type brake head and brake beam frame matching part, adopt the twin fillet wolt grooved to be welded to connect.
The utility model has the advantages that: intensity is high, abrasion loss is little, long service life, economical with materials, prolongation accessory life-span, reduce the cost of overhaul, be prone to realize stream line operation and mechanization assembling, to improving vehicle braking performances, riding quality and operation stability significant effect arranged.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the axonometric drawing of channel-section steel brake beam frame;
Fig. 3 is the structural representation of slide block type brake head;
Fig. 4 is the birds-eye view of Fig. 3.
The specific embodiment:
With reference to accompanying drawing, the utility model comprises channel-section steel brake beam frame 1, brake head 2, and brake head 2 is the slide block type brake head, at channel-section steel brake beam frame 1 two ends a brake head 2 is installed respectively.Channel-section steel brake beam frame 1 comprises channel beam 4 and arcuate slots girder steel 6, and the channel beam 4 older type channel beam length of the utility model shorten to some extent, and with two ends channel cross-section bevel, can match with the arcuate slots girder steel 6 of the utility model; The arcuate slots girder steel of the utility model increases length on the basis of old type arcuate slots girder steel, and two ends are bent into certain angle, makes its two ends can assemble the slide block type brake head; Channel beam of the utility model and arcuate slots girder steel centering welding assembly at middle mounting column 5, constitute the channel-section steel brake beam frame of the utility model.Slide block type brake head 2 is on the end face of brake shoe base body, to have square mounting hole 7, and on the end face of brake shoe base body, to be provided with the cross section be hexagonal slide block 3.
The slide block type brake head is compared with old type channel-section steel brake head; Adopt and brake head sliding block type structure cast in block, replaced the welding assembly structure of roller, Roller Shaft and brake head, make joint form between brake beam and the bogie side frame chute contact the face that becomes the hexagon slide block and contact by the line of cylindrical roller; Limited the rotation of brake beam; Brake shoe center of gravity and brake beam center of gravity are in the same plane, and the brake shoe top and the bottom are stressed more even, thereby reduce the possibility that produces brake shoe partial wear; Adopt casting integrated sliding block type structure, cancelled the weld seam of Roller Shaft and brake head joint portion, make the intensity at this position also increase.Two slide block type brake heads are sleeved on channel-section steel brake beam frame two ends, carry out the welding of grooved weld seam, be assembled into slide block type channel-section steel brake beam at binding site.During train braking, be delivered to the braking force on the brake beam frame, the dogleg section through new arcuate slots girder steel two ends promotes brake head, makes the brake shoe wheel that reclines, and reaches the purpose that makes train braking slow down or stop.Transmit in the process of braking force to brake head at brake beam frame; The dogleg section at the arcuate slots girder steel two ends of the utility model is only come from the compression effort of brake head; The weld stressing conditions at brake beam frame two ends more rationally, has reliably been eliminated the possibility that old type channel-section steel brake beam this position when train braking receives tensile stress to cause weld seam to be torn.
