Abstract
The present invention features that by means of one group of friction wheel, brake, driving and connecting levers and brake shoe, the heat energy, which is concentrated in wheel contact surface, is partially separated to the brake to disperse through the dynamic contact of the friction wheel to the contact surface, so that the train can be braked effectively under the common action of the brake shoe and the brake.
Description
The present invention relates to a kind of railroad train with braking method and device, belong to train braking method and brake equipment class.
The used drg of China's train has two classes at present, and one is block brake, and two is brake shoe, the hybrid drg of disc braking.Use practice for many years shows above-mentioned two braking structures, certain limitation and deficiency are respectively arranged, brake shoe type drg only is used for lorry, because the thermal power when it plays brake action concentrates on the wheel place, the institute so that leverage ratio be restricted, otherwise can cause that wheel produces fire crack because of heat energy is excessive, cause the braking failure to bring disaster to traffic safety.And,, unsprung weight is increased because brake disc is installed on the axletree to being used for the hybrid brake structure that combines by brake shoe and disc braking of passenger vehicle, consume the certain tractive output of train; Influence the dynamic performance of train operation; Simultaneously also owing to wheel shaft increased as main load member it is stressed, very easily to the intensity of wheel shaft and bring adverse effect service life; And this kind structure also is unfavorable for repair and maintenance.
Purpose of the present invention, aim to provide a kind of braking method and brake equipment that more adapts to train operation, wish that it can be under the prerequisite that satisfies train high speed, heavy service, can not only realize the effective braking in the safe stopping distance, and can accomplish neither to increase unsprung weight again, heat energy dissipation position does not concentrate on the wheel tread yet simultaneously.
Above-mentioned purpose is realized by following technical proposals.
This railroad train is with braking method and device, its braking method is: by being installed in one group of friction wheel (5) and the drg (6) on the brake axle at the bottom of the car, make running train when drag, this friction wheel (5) can be pressed on the wheel road surface, the heat energy branch some of changing when making kinetic-energy braking is not distributed on wheel tread, but kinetic energy pass in the supporting drg (6) of this friction wheel on, by fast brake shoe (10) and friction wheel (5) then contact with the wheel road surface simultaneously to produce and brakes.
Described train brake equipment, form by frame (11), brake shoe (10), drg (6), friction wheel (5), brake axle (4), braking dowel bar (1), lever (9), dowel bar (7), component lever (8) and truck dead lever (3), wherein the fast brake axle of institute (4) is located on the frame (11), and with axletree in the same way, the both sides of this brake axle (4) respectively establish one group the braking usefulness drg (6) and friction wheel (5), the below of frame (11) then be provided with one group with the supporting brake shoe (10) of friction wheel (5) and wheel road surface; Described drg (6) and is associated with brake shoe by frame (11) again through braking dowel bar (1), truck dead lever (3), dowel bar (7), connect with component lever (8).
According to above method and design plan design-calculated train brake equipment, compare with habitual at present train braking device, accomplished neither to increase unsprung weight, simultaneously make heat energy dissipation position not concentrate on the wheel tread again, make train can realize at a high speed, under the heavily stressed prerequisite, realize the effective braking in the safe and effective stopping distance, improve the safety of train operation, reliability.
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is the lateral plan of accompanying drawing 1.
Among the figure each partly member title is as follows: 1, braking dowel bar, 2, lever connection, 3, truck dead lever, 4, brake axle, 5, friction wheel, 6 drgs, 7, dowel bar, 8, the component lever, 9, lever, 10, brake shoe, 11, frame.
Further set forth the present invention below in conjunction with accompanying drawing, and provide embodiment.
When adopting above method and apparatus to brake train, before braking in a flash, the some of kinetic energy because train moves ahead, reach drg (6) the synchronously rotation coaxial by the friction wheel (5) of being located at brake axle (4) outer end and contacting, also promptly part kinetic energy has been delivered on the drg (6) with this friction wheel (5) with wheel tread; Because the joint efforts of numerous levers, and under the effect of frame (11), when braking dowel bar (1) by band brake apparatus, when holding drg (6) tightly, this promptly is dissipated on the drg (6) through the kinetic energy that friction wheel (5) is delivered on the drg (6) with the heat energy form; And meanwhile, brake shoe (10) also produces with the wheel of motion and contacts, and this separates later part function, and also the form of distributing with heat energy under the effect of brake shoe (10) is dissipated in the contact interface of brake shoe (10) and wheel tread.Because the separation of function, the partly dissipation of heat energy is so can protect train wheel effectively.
