Abstract
The present invention is a kind of brake equipment that is used on the rail vehicles.The object of the present invention is achieved like this: hold wheel on wheel vertical center line top tightly with brake shoe, produce friction force, thereby make the wheel resistance that rotates, realize the purpose of braking.
Description
The present invention is a kind of brake equipment that is used on the rail vehicles.
At present the railway rolling stock brake method all is in wheel horizontal center line both sides or one-sidedly holds wheel tightly with brake shoe, produces friction force, thereby makes wheel produce brake resistance, realize the purpose of braking, yet this kind braking method, shortcoming is a lot, and stopping distance is longer.
Purpose of the present invention is exactly to solve in wheel horizontal center line both sides or the defective that single shoe brake produced.
The object of the present invention is achieved like this: hold wheel on wheel vertical center line top tightly with brake shoe, produce friction force, thereby make the wheel resistance that rotates, realize the purpose of braking.
Foundation brake rigging used in the present invention is all simpler than existing any foundation brake rigging, and parts are few, and cost is low, and is convenient to the cross-check sum repairing, can alleviate the car body deadweight.Braking is stable, can reduce the longitudinal direction of car impulsion, acts on during release of brake rapidly, and brake efficiency improves.Because the method can improve grip of wheels at glancing impact, so can shorten stopping distance in a large number, reduce brake shoe and wheel wear, can dwindle auxiliary reservoir and brake cylinder volume, can save pressure air, braking force uneven phenomenon between each brake shoe can not appear, thus brake block abrasion degree unanimity, the eccentric wear free phenomenon.So owing to adopted afterbody taper round pin easily to install, hand brake mast has been owing to adopted the middle part square, so made things convenient for the row inspection worker lock operation of loosing one's grip, promptly laborsaving safety again.
Fig. 1: the brake foundation brake is put view
Fig. 2: hand brake mast view
Fig. 3: afterbody taper round pin view
Fig. 4: brake head view
The invention will be further described below in conjunction with accompanying drawing:
With reference to Fig. 1: miniature brake cylinder (2) is installed in the outside on bogie side frame (1), the installed inside fulcrum block (4) on bogie side frame (1).Work as glancing impact, the push rod (13) on the miniature brake cylinder (2) is released, and drives lever (3) upward movement, power is delivered on the brake head (5) by fulcrum block (4) and afterbody taper round pin (9), be delivered to again on the brake shoe (6), make brake shoe (6) hold wheel (7) tightly, produce braking.
When alleviating, push rod (13) and lever (3) be by the tension of action of gravity and spring (8), thereby make brake shoe (6) leave wheel (7).
Pulley (12) and steel rope (10) use when hand braking.Pulley fulcrum (11) is fixed on the car body.
With reference to Fig. 2: when hand brake used, hand brake mast (15) rotated, and drove steel rope (10).Link stopper (14) blocks steel rope to after contraction, steel rope (10) by pulley (12) thus arriving lever makes lever generation brake action.
Hand brake mast just rotates round about and can alleviate.
The hand brake mast middle part is a square.
With reference to Fig. 3: a 〉=3mm d≤1/2D
With reference to Fig. 4: this brake head can be installed high friction composite brake shoe, and the intensity height.
Claims (3)
1, a kind of braking method, form by miniature brake cylinder (2), lever (3), fulcrum block (4), afterbody taper round pin (9), brake head (5), release spring (8), hand brake mast (15), steel rope (10), link stopper (14), it is characterized in that: hold wheel on wheel vertical center line top tightly with brake shoe and produce friction force, thereby make wheel produce brake resistance, realize the purpose of braking.
2, braking method according to claim 1 is characterized in that: the hand brake mast middle part is a square.
3, braking method according to claim 1, it is characterized in that: the round pin afterbody is taper.
