Abstract
The invention is a center rotation connector for connecting brake head and brake beam of the railway carriage. It permits the brake head to regulate the radial and sideways direction with controllable rotation degree, makes the brake shoe adaptive to the frame of the wheel, thus brake shoe can reach to enough force distribution, and the utilization of the brake shoe material can be optimized.
Description
Technical field
The present invention relates to be used for a braking assembly of the brake beam of railcar, specifically, relate to the braking head that is pivotally connected to a railcar and the pivot fitting of brake beam, can realize along the transmission of the enough power of brake shoe by this joint, and the enough contacts between brake shoe and the railcar steering framing wheel.
Background technology
Most of railroad freight cars use a kind of mechanism that is referred to as brake equipment, it generally is categorized as car body installation system (BMS, actuator devices is on compartment platform), direct acting lorry installation system (TMS-DA, actuator devices is on beam) or non-direct acting lorry installation system (TMS-IA, actuator devices on lorry, by leverage on the brake beam of standard).
In general, on car body, be equipped with one and provide compressed-air actuated air holder brake cylinder.In a BMS, brake cylinder comprises that by one the system of bar and activation lever offers a lorry activation lever system with mechanical force again, and it generally includes two activation lever and a pipe link.Activation lever moves brake beam, and brake beam is applied to power on the tread of wheel by detouchable friction shoe or brake shoe, thus the rotation that slows down wheel.
Traditional TMS brake transsmission device comprises two brake beams on every lorry, at least one brake cylinder assembly on the per car, and an activation lever or the coupling assembling between brake beam and brake cylinder.
There is the brake beam of numerous species type to be used in combination with above-mentioned traditional braking device.Wherein the most frequently used a kind of brake beam comprises: a depression bar, one its end be connected on the end of depression bar, V-shaped pull bar roughly, one is connected the braking head on each end of depression bar and/or pull bar, comprise that respectively one has the brake shoe frame of a brake shoe, two end extensions, respectively be connected each end of pull bar and/or depression bar, or brake beam is connected to suspension gear on the bogie truck of railcar by it, and a fulcrum assembly that is connected on depression bar and the pull bar, so that fulcrum still remains between pull bar and the depression bar.In prevailing TMS-DA, be installed in the cylinder component on one of them beam in addition, it is connected on its depression bar, and the relative beam on this lorry has a fulcrum or connecting device on depression bar, so that the power of cylinder is delivered on two beams, one automatic double acting adjust the clearance device is arranged between two beams, and it extends by a binary pair, with the wearing and tearing of compensation brake shoe.
Usually, braking head is fixedly connected on the brake beam, and they are by means of the perforation at the place, end of bolt by being positioned at brake beam, and a captive joint is implemented in a perforation that is positioned at braking head place.Also have, directly be welded on the end of brake beam by braking head, realization braking head is connected with brake beam, perhaps, in the situation of casting beam, can be made into integration with beam-ends.
Becoming flexible between all extensions of brake beam and guide thereof (in order to compensate the motion of lorry parts, being necessary when it is operated) can cause brake beam to hang from lorry, and like this, non-braking position does not point to the center of wheel.In addition, in brake operation course, owing to be fixedly coupled a little between the extension of brake beam and lorry guide thereof, between the wheel in braking head and the brake operation course, and between braking head and the brake beam, exist two-fold constraint, it fastens the displacement of beam in some way in the lorry guide, and towards the alignment certainly of taking turns subcenter, like this, the power that applies by the braking head can not transmit equably along brake shoe, thus, produces the inhomogeneous and incomplete wearing and tearing of the useful materials of brake shoe, this is the waste to useful materials that originally can suitable use, therefore, must change the brake shoe material frequently, this is a kind of waste of time and money.What in many cases, this uneven tapering wearing and tearing stayed is such brake shoe material: the bottom of brake shoe is just the same with news, and its top has reached the limit of use, like this, forms 50% waste of material.
Under opposite extreme situations, the metallic contact that the wearing and tearing of brake shoe material on some point have made the brake shoe frame causes the damage of brake shoe frame and wheel to corresponding bogie truck wheel.
Also have a general problem to be, along with its circulatory life-time is used up in the compartment, all parts of its brake equipment little by little wear and tear, and the sagging and situation that fasten of aforesaid beam becomes seriously, therefore, along with wearing out of vehicle, further shorten the service life of brake shoe.
Therefore, requiring has a kind of braking head, its can control brake head around " Z " axis (vertically rotating) with around the degree of rotation of " Y " axis (lateral rotation) so that brake shoe pivots, thereby fully be suitable for the tread of taking turns on " Z " and " Y " axis.
Consider the problems referred to above, the applicant develops a kind of pivotable pivot fitting of braking head and brake beam that is used for connecting pivotly, this joint connects braking head and brake beam pivotly, so that braking head with respect to wheel with the correction of controollable degree of rotation its radially with the direction of side direction, thereby make brake shoe be adapted to the tread of wheel, and reach the distribution of sufficient power along brake shoe.
Applicant's the braking head that connects pivotly comprises with the pivot fitting of brake beam: be used for being connected pivotly the braking head to brake beam so that the braking head device of pivot radially; Be used for connecting pivotly pivot fitting to brake beam so that the device that a pivot fitting and braking side direction pivots: be used for being connected the friction gear of braking head pivotly to the device cooperation of the connecting device that pivots, this friction gear is used for limiting the motion of braking head with respect to the pivot connecting device; And the mechanical rotation restraint device, it is used for the radially pivot angle of braking head is limited between the predetermined angular range.
Adopt applicant's pivot fitting, can utilize all useful materials of brake shoe fully, therefore, avoid changing frequently the material of brake shoe, because replacing can cause high maintenance cost frequently, so this helps to save a large amount of money, and if the thickness of the remaining material that avoids waste be uniform words, the useful brake shoe material that originally can continue to use.
And, because the degree of rotation of braking head, can reduce the twisting resistance that lever causes in operating process on some angle, therefore, by avoiding fastening of described element, and allow brake actuating system that all wheels on the vehicle are applied uniform power, can prolong the life-span of pin, groove guide and beam itself.
