Method for preventing wheel pairs from slipping when braking railway car

FIELD: railway transport.SUBSTANCE: invention relates to the field of rail vehicles, in particular to anti-skid systems. A method for preventing wheel pairs from slipping when braking a railway car is characterized by that optoelectronic sensors detect a change in the intensity of a luminous flux relatively to a reference value during the rotational movement of a wheel pair. Then, the luminous flux is converted into pulse signals with a repetition frequency directly proportional to the angular velocity of the wheel pair. Pulse signals are transmitted to an input of a control module of an electronic unit, located in a brake equipment unit, where deviations of the repetition frequency of pulse signals from the reference value are calculated. Based on the calculated deviation, time of air discharge from a brake cylinder and duration of a single exposure to a three-position relief valve are calculated. Then, by giving a control command from the electronic unit, the three-position relief valve is opened, thereby discharging air from the brake cylinder into the atmosphere, thereby preventing slipping of wheel pairs. Next, compressed air is supplied from the brake equipment unit to brake cylinders to a normal level.EFFECT: reduction in the wheel pair skid during braking of a railway car.1 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 770 941 C1 (51) МПК B61C 15/08 (2006.01) B60T 8/00 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B61C 15/08 (2022.02); B60T 8/00 (2022.02) (21)(22) Заявка: 2021139058, 27.12.2021 (24) Дата начала отсчета срока действия патента: Дата регистрации: 25.04.2022 (45) Опубликовано: 25.04.2022 Бюл. № 12 2 7 7 0 9 4 1 R U (56) Список документов, цитированных в отчете о поиске: EA 201800223 A1, 30.08.2019.

Elastic mounting of a hydraulic unit in a vehicle brake system

It is a known fact that a hydraulic unit in a motor vehicle braking system can be elastically suspended by using at least two hollow cylindrical rubber-elastic elements, into which pins jutting out from the hydraulic unit protrude, wherein the pins are directed in a substantially horizontal manner and the rubber-elastic elements are inserted into lower partial bearing cups and are inhibited by upper partial bearing cups at the exit from the lower partial bearing cups. In order to facilitate assembly, the invention provides that the upper partial bearing cups (8) are configured in such a way that they can be assembled from above in a substantially radial position with respect to the rubber-elastic elements (13). In order to provide secure positioning, a bracket (32) runs, for instance, from the upper partial bearing cup (8), and grasps the lower bearing cup by pivoting underneath it to solidly encircle the rubber-elastic element (13).

Process and device for stabilizing a vehicle on the basis of a determined torsional value

A method for stabilizing a vehicle to avoid at least one of a vehicle rolling over about a vehicle axis oriented in the longitudinal direction of the vehicle and the vehicle sliding in the transverse direction. The method determines at least one of a torsion variable that corresponds to how the vehicle behaves in reaction to a force acting on the vehicle about the vehicle axis oriented in the vehicle's longitudinal direction, and a load-shift variable that corresponds to how the vehicle load behaves in reaction to a force acting upon the vehicle. The method determines a vehicle speed and also determines at least one threshold value for the vehicle speed based on the torsion variable and the load-shift variable. The vehicle speed and the at least one threshold value are then compared, and interventions (or measures) are taken to stabilize the vehicle based on the comparison.

Method of brake pressure control in automobile brake system protected from locking

FIELD: automotive vehicles; brake systems. SUBSTANCE: method of brake pressure control in brake system protected from locking provides for measuring slip and/or deceleration or brake wheel in regular way comparing obtained value with preset threshold value and reducing braking pressure, if preset value is exceeded. To ensure against undesirable drop of braking pressure, threshold value for preset time intervals is first raised relative to main value (S G ) and then reduced again. At moment T 1 of time at which deceleration of brake wheel rotation exceeds physically possible deceleration of vehicle, threshold value is abruptly raised and then reduced according to preset time function. During reduction of threshold value, change of speed of braked wheel at preset time intervals ΔT is measured and result is compared with momentary rise of threshold value, and if comparison shows that change of speed exceeds momentary rise of threshold value, the latter is reduced to main value.

Accumulator for a braking system

A spring accumulator (56) is used in conjunction with a modulation valve (30) to provide an operating mechanism for an hydraulic anti-skid braking system. The modulation valve includes shut-off valve means (44) to close off communication between an hydraulic pressure source (40) e.g. a master cylinder operated by the driver's foot, and a brake operating mechanism e.g. a wheel cylinder, and a modulation chamber (32) having a modulation plunger (35) which can move to vary the available chamber (32) volume and hence vary the hydraulic pressure in the chamber when the shut-off valve (44) is closed. The modulation plunger is connected to the spring accumulator (56) by a right-angle lever arrangement (63-61-64). The spring accumulator includes a movable plate (56) which is indexed by a pilot plunger (53) under the control of hydraulic pressure associated with the modulation valve (30). Work done by the outward displacement of the modulation plunger (35) can be stored as potential energy in the spring (59) of the accumulator and re-used to assist the return of the modulation plunger (35) to its resting state. The return movement of the modulation plunger is controlled by a small vacuum operated piston and cylinder (70) which can be of relatively low power as the spring accumulator (56) provides most of the energy required to balance the hydraulic pressure acting on the plunger. The right angle lever arrangement (63-61-64) and movement of the accumulator plate (56) allows the spring (59) to be locked in its compressed state (with the modulation chamber at low pressure) until activation of the spring is required to assist in returning the plunger to a higher pressure position.

Method for measuring the braking force on the steerable front wheels of an essentially stationary motor vehicle

Die Erfindung betrifft ein Verfahren zum Bemessen der Bremskraft insbesondere an den lenkbaren Rädern, insbesondere Vorderrädern eines zweispurigen, im wesentlichen stillstehenden Kraftfahrzeugs, wobei während einer durch Lenkvorgabe hervorgerufenen Einschlagbewegung der lenkbaren Räder die an diese angelegte Bremskraft verringert wird. Dabei wird zumindest in gewissen Betriebszuständen an den Vorderrädern entweder eine pulsierende Bremswirkung erzeugt oder es wird beim Lenken nur das jeweils kurveninnere gelenkte Rad gebremst. Die pulsierende Bremswirkung kann abwechselnd am rechten bzw. linken gelenkten Rad erzeugt werden. Die vorgeschlagenen Maßnahmen reduzieren die benötigte Lenkkraft. The invention relates to a method for measuring the braking force, in particular on the steerable wheels, in particular front wheels of a two-lane, essentially stationary motor vehicle, the braking force applied to the steerable wheels being reduced during a steering movement caused by the steering command. At least in certain operating conditions, either a pulsating braking effect is generated on the front wheels or only the wheel steered inside the curve is braked when steering. The pulsating braking effect can be generated alternately on the right or left steered wheel. The proposed measures reduce the steering effort required.

Hydraulic fluid control apparatus

In the field of avionics, it is difficult to justify initiation of new aircraft programmes for replacement of small numbers of niche aircraft. Instead, in many cases, retrofitting existing aircraft is preferred for economic reasons. In this respect, upgrading existing braking systems to accommodate replacement of existing brake units employing sintered friction materials with brake units employing carbon-carbon composite friction materials is desirable. However, when upgrading the braking systems it is necessary to ensure that the integrity of the existing airframe is not compromised by the use of the new brake assemblies employing the carbon-carbon composite friction materials. Consequently, the present invention replaces existing pressure control valves of existing braking systems with an electronic control unit (126) coupled to a pressure control servovalve (128), thereby ensuring proper application of hydraulic pressure to brake assemblies (122). An advantage of this invention is that the pressure profile of the hydraulic fluid is controllable and hence the integrity of the airframe is maintained.
