Abstract
The invention relates to a brake head overturn-proof structure of a tread brake of a rail vehicle. The brake head overturn-proof structure of the tread brake of the rail vehicle comprises a brake head and a dovetail groove base which are hinged and fixed on the lower end of a hanging rod, and a lead screw head which is fixed on the front end of a brake lead screw. The brake head comprises a left plate and a right plate, and the left plate and the right plate are respectively provided with column grooves located under the hinging point of the brake head; the dovetail groove base is provided with a rear dovetail groove and a lower clamping plate inserted between two column grooves of the brake head, and the lead screw head is provided with a slider matched with the dovetail groove; damping components are installed in two column grooves of the left plate and the right plate, and used for applying the clamping force to the clamping plate, and preventing the brake head from overturning. A disc spring is pressed by a plug, and a friction block is pressed by the disc spring. In the process of braking, the clamping plate is forwards pushed with the dovetail groove base, the friction force between the friction block and the clamping plate produces the friction moment relative to the hinging center of the brake head, so the brake head is prevented from overturning because of the gravity of the brake head.
Description
Technical field
The present invention relates to the brake head of the tread brake device of rail traffic vehicles, particularly the anti-countersunk head mechanism of brake head, belongs to railway vehicle braking systems technology field.
Background technology
Rail traffic vehicles tread brake device is when applying braking, screw mandrel and brake head mechanism release, the center of gravity of brake head mechanism is not or not the hinged center of clamping plate and brake head, and the center of gravity of brake head is formed centrally a moment in hinged, easily causes brake head to make brake head overturn because of gravity.
Finding through inspection, Chinese invention patent application CN 103693069 A, discloses a kind of Tread brake device, utilizes the damper assembly be arranged on brake head for preventing countersunk head.Its damper assembly comprises the friction shoe screwing the gland in brake head biside plate tapped bore, the compression disc spring in gland inner chamber and be clamped between compression disc spring and baffle plate, and baffle plate is connected in order to transmission braking force with drg screw mandrel.Apply appropriate power to adjusting head by disc spring, friction shoe, thus when ensureing Vehicular vibration, brake head can not rock swing with vibration, and when braking, under enough brake shoe positive pressure, brake head can swing, so that brake shoe can better be adjacent to wheel tread.
The anti-countersunk head mechanism of above brake head, structure is simple, but between brake head and adjusting head, gap is comparatively large, and when installing disc spring and friction shoe, the easy landing of friction shoe, maintenance is wasted time and energy.
Summary of the invention
Technical matters to be solved by this invention is, overcomes the above-mentioned shortcoming of prior art, provides a kind of guideway vehicle tread brake device brake head overturn-proof structure.
In order to solve above technical matters, brake head provided by the invention, is hingedly fixed on suspension rod lower end, and comprise left side board, right side board, left side plate is respectively equipped with the cylinder groove be positioned at below brake head hinge-point;
Dovetail groove pedestal, is hinged on the hinge-point of brake head, and its rear portion has vertical dovetail furrow, and bottom has the clamping plate inserted between brake head two cylinder groove;
Screw mandrel head, is fixed on the front end of drg screw mandrel, has the slide block coordinated with vertical dovetail furrow;
Be provided with damper assembly in two cylinder grooves of left side plate, to apply Clamping force to clamping plate, prevent brake head from overturning.
In order to solve the problems of the technologies described above further, this guideway vehicle tread brake device brake head overturn-proof structure also has following improvement:
1, described damper assembly is made up of the friction shoe be successively set in cylinder groove, cushion block, disc spring, screw plug, and described screw plug and cylinder groove are spirally connected, and after screwing screw plug, friction shoe and clamping plate push against.
2, the slide block of screw mandrel head inserts after dovetail furrow, only can relative sliding in a vertical direction.
3, described dovetail furrow can be substituted by T-slot.
During braking, dovetail groove pedestal is released by screw mandrel head, because dovetail groove pedestal is hinged on suspension rod, therefore in the process released, produce the movement of vertical direction between dovetail furrow and screw mandrel head, and do not relatively rotate, visible, the intermediate plate of dovetail furrow and its underpart can only keep motion of translation, and the friction force of intermediate plate can be utilized to ensure that brake head does not overturn.Alleviation process in contrast, equally can the effect of the side's of playing countersunk head.
Due to can relative sliding between dovetail furrow and slide block, therefore screw mandrel bears the power except axially hardly, therefore drg stability and reliability higher.
Brake head overturn-proof structure of the present invention two groups of disc springs, pressing friction sheet, make to produce a friction force between friction lining and clamping plate, relative to brake head hinged in be formed centrally a friction moment, the moment formed with the gravity of brake head balances mutually, brake head can stretch out by pulsation-free, release power is applied to wheel tread, makes car retardation and parking.
In addition, this brake head overturn-proof structure, improves in original tread brake device, disc spring is loaded in threaded sleeve, then installs from brake head both sides, and the caducous shortcoming of friction shoe, is convenient to installing/dismounting, improves work efficiency.

1-brake head, 1.1-cylinder groove, 2-screw plug, 3-disc spring, 4-friction shoe, 5-cushion block, 6-clamping plate, 7-suspension rod, 8-hinge-point, 9-screw mandrel head, 10-slide block, 11-dovetail furrow, 12-dovetail groove pedestal.
Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1 and Figure 2, the present embodiment guideway vehicle tread brake device brake head overturn-proof structure, comprise the hinged brake head 1 and the dovetail groove pedestal 12 that are fixed on suspension rod 7 lower end, be fixed on the screw mandrel head 9 of drg screw mandrel front end, brake head 1 and the public hinge-point 8 of dovetail groove pedestal 12.Its dovetail groove pedestal 12 rear is provided with vertical dovetail furrow 11 (also can substitute by T-slot), and screw mandrel head 9 has the slide block 10 inserting this dovetail furrow 11, and both can at vertical direction relative sliding.Brake head 1 has left side board and right side board, left side plate is respectively equipped with the cylinder groove 1.1 be positioned at below brake head 1 hinge-point 8, dovetail groove pedestal 12 has the clamping plate 6 inserted between left side plate cylinder groove 1.1, friction shoe 4, cushion block 5, disc spring 3, screw plug 2 is provided with successively in cylinder groove 1.1, screw plug 2 and cylinder groove 1.1 are spirally connected, and after screwing screw plug 2, friction shoe 4 and clamping plate 6 push against, to apply Clamping force to clamping plate 6, prevent brake head from overturning.
When in braking procedure, dovetail groove pedestal with clamping plate is pushed forward out, friction force between friction shoe and clamping plate produces friction moment relative to the hinged center of brake head, and prevent from making brake head overturn due to the gravity of brake head, mechanism's fitting operation was more convenient relatively in the past.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
