Abstract
The utility model provides a locomotive tread unit brake with a self-location brake head, which comprise a pressure working cavity mechanism (1) and a brake shoe force transmission mechanism. An elastic damping device (3) is arranged on the brake shoe force transmission mechanism, one end is hinged at a hinge connection point (6) of a support (4) and a connection rod (5) of pressure working cavity mechanism (1), and the other end is hinged a hinge point (7) of the protrusion portion of a brake head (2). The locomotive tread unit brake with the self-location brake head can smoothly resolve the problems that a brake head support device structure is lack of stability and damping effect of an exposed friction pair is prone to change to cause upper and lower eccentric friction of brake shoes.
Description
Technical field
The utility model relates to the railway locomotive technology, relates in particular to the locomotive tread units drg of the customized position of a kind of brake head.
Background technology
Locomotive tread units drg is to be the foundation brake rigging that is used for the locomotive wheel tread brake of propulsion source with the pressurized air, is the final device for carrying out said of locomotive brake function, for the safe in operation of locomotive provides safeguard, on various kinds of vehicles, is widely used.Brake shoe is straight with wheel tread.Wipe contact produces the friction element of braking force, and brake head then is the installation elements of brake shoe on the unit brake.When brake head and wheel relative position relation were correct, the gap between brake shoe and the wheel kept evenly.When brake head and wheel relative position relation mal, the gap between brake shoe and the wheel can't keep evenly, and brake shoe produces the upper and lower irregular wear, and eccentric wear up and down takes place.Upper and lower eccentric wear takes place brake shoe will make the brake shoe life-span significantly descend, and have to often change, and increase the locomotive operation cost.Brake shoe and wheel tread behind the eccentric wear can not be fitted fully simultaneously, causes braking force to descend.
Representative type locomotive tread units brake structural such as accompanying drawing 1a and accompanying drawing 1b.Brake head (2) is installed on the support (4) in the pressure epitrochoidal chamber mechanism (1) through connecting rod (5) suspension.Support (4) is a fulcrum one (6) with the hinge-point of connecting rod (5), and brake head (2) is a fulcrum two (8) with the hinge-point of connecting rod (5).In the circular hole at connecting rod (5) middle part, brake head registration device (17) is set.This installs built-in dish spring (16) as elastic element, and 1 friction shoe (15) respectively is equipped with at the two ends, hole.The elastic force promotion friction shoe (15) that provides with dish spring (16) compression stretches out from the hole and brake head (2) inside face friction, produces frictional damping, makes brake head (2) in the space, keep the fixed position.But the hinge-point of support and connecting rod---fulcrum one (6), the hinge-point of brake head and connecting rod---fulcrum two (8) and brake head registration device (17) are on same straight line, and the structure deficient in stability is subject to the external force influence.Outside the inside face of brake head (2) inside face and friction shoe (15) composition friction pair is exposed to, be subject to the dirt influence, cause the two friction coefficient to change, influence damping.The problems referred to above have directly caused brake head (2) and wheel can't keep correct relative often, cause the upper and lower eccentric wear of brake shoe.
The utility model content
The purpose of the utility model overcomes the deficiency of above-mentioned prior art exactly, and a kind of locomotive tread units drg that improves brake head positional structure stability, avoids the customized position of later-model brake head of the upper and lower eccentric wear of brake shoe is provided.
The purpose of the utility model is existing like this: the locomotive tread units drg of the customized position of a kind of brake head; Comprise pressure epitrochoidal chamber mechanism (1) and brake shoe force transmission mechanism; It is characterized in that on the brake shoe force transmission mechanism, being provided with elastic damping device (3); One end of said elastic damping device (3) is articulated in the support (4) of pressure epitrochoidal chamber mechanism (1) and the hinge-point (6) of connecting rod (5), and the other end is articulated in brake head (2) protrusion hinge-point (7).
For the better purpose that realizes the utility model; Said elastic damping device (3) is made up of bearing (9), elastic damping cover (10), end cap (11) and fulcrum (12); The end cap (11) that has sealing dust-proof device is installed in elastic damping cover (10) in the bearing (9); The bar portion of fulcrum (12) upper end is inserted in the elastic damping cover (10); And the latter slides relatively, and bearing (9) is hinged with support (4) and connecting rod (5) through the hole (13) of upper end, and fulcrum (12) is hinged at the protrusion hinge-point (7) of brake head (2) through the hole (14) of lower end.
For the better purpose that realizes the utility model, said elastic damping cover (10) is the elastic damping element that metal and High molecular material are composited.
Adopt the scheme of the utility model, can solve smoothly because of brake shoe restitope apparatus structure deficient in stability, friction pair are exposed to outer damping and be prone to change the upper and lower eccentric wear problem of brake shoe that causes.
