Abstract

In a braking arrangement for a rotating member such as an automotive vehicle wheel and which has a fluid pressure actuated brake for slowing the rotating member together with a booster for increasing the fluid pressure imposed on the brake to a pressure higher than the pressure imposed by an operator, a sensor for signalling the occurrence of an excessive rate of retardation of the braked rotating member and a booster spoiler operatively connected with the booster and the sensor and responsive to a signalled occurrence of an excessive rate of retardation for decreasing the increased fluid pressure imposed by the booster. The booster may be either pneumatic or hydraulic, with corresponding variations, in the specific form for the booster

And - the valve regulator, a section.

Система включает главный тормозной цилиндр 1 с усилителем 2, который может быть вакуумным (фиг.1 и 2) или работать на сжатом воздухе (фиг. 3). Цилиндр 1 соединен трубопроводом с колесным цилиндром тормозного механизма 3 колеса 4. Вакуумна  камера усилител  2 (фиг.1 и 2) подключена маг-истралью 5 к источнику вакуума, например всасывающему трубопроводу двигател  6 внутреннего сгорани . В магистраль 5 встроен клапанный регул тор 7 (фиг. 1), состо щий из электромагнитного клапана, имеющего установленный в корпусе 8 шток 9 с укрепленными на нем клапанными дисками 10 и 11 дл  взаимодействи  с клапанными седлами 12 и 13. Диск 11 предназначен дл  разобщени  входного канала 14 и канала 15, а диск 10 - дл  разобщени  канала 14 и атмосферного канала 16. Цружина 17 нормально прижимает диск 10 к седлу 12, при этом сообщение между каналами 14 и 15 открыто. Шток 9 св зан с  корем 18 электромагнита, катушка 19 которого св зана проводами 20 с датчиком 21 чрезмерного замедлени  колеса 4. Атмосферный канал 16 сообщен с атмосферой посредством регулируемого обратного клапана 22, состо щего из клапанного элемента 23, седла 24, регулир тощей пружины 25 и стопорного элемента 26. Регулировка клапана 22 осуществл етс  резьбовыми детал ми 27 и 28.The system includes a master brake cylinder 1 with an amplifier 2, which can be vacuum (Figures 1 and 2) or operate on compressed air (Fig. 3). The cylinder 1 is connected by pipeline to the wheel cylinder of the brake mechanism 3 of the wheel 4. The vacuum chamber of the amplifier 2 (Figures 1 and 2) is connected by a magistral 5 to a vacuum source, for example the suction pipe of the engine 6 internal combustion. A valve regulator 7 (Fig. 1) is built in line 5, consisting of a solenoid valve having a rod 9 mounted in the housing 8 with valve discs 10 and 11 mounted on it to interact with valve seats 12 and 13. The disk 11 is intended to separate the input channel 14 and channel 15, and the disk 10 - to separate the channel 14 and the atmospheric channel 16. The spring 17 normally presses the disk 10 to the seat 12, while the communication between the channels 14 and 15 is open. The rod 9 is connected to the core 18 of the electromagnet, the coil 19 of which is connected by wires 20 to the sensor 21 of excessive wheel deceleration 4. The atmospheric channel 16 is connected to the atmosphere by means of an adjustable non-return valve 22 consisting of a valve element 23, a seat 24, an adjusting spring 25 and a locking member 26. The valve 22 is adjusted by threaded parts 27 and 28.

Торможение колеса 4 с помощью насто щей системы осуществл етс  путем воздействи  на педаль цилиндра 1.При выдаче датчиком 21 сигнала о чрезмерном замедлении колеса срабатывает регул тор 7. Диск 11 перекрывает сообщение между каналами 14 и 15, а диск 10, отойд  от седла 12, сообщает канал 14 с атмосферой через канал 16 и клапан 22. Разр жение в вакуумной камере усилител  2 снижаетс  и, какWheel 4 is braked with the help of the present system by acting on the pedal of cylinder 1. When the sensor 21 signals that the wheel is decelerating excessively, the regulator 7 is activated. The disk 11 blocks the communication between channels 14 and 15 and the disk 10 moves away from the saddle 12, communicates channel 14 to the atmosphere through channel 16 and valve 22. Discharge in the vacuum chamber of amplifier 2 decreases and, as

следствие этога, снижаетс  давление на выходе цилиндра 1. Степень снижени  разр жени  в вакуумной камере усилител  2 определ етс  настройкой клапана 22. При прекращении сигналаAs a result, the pressure at the outlet of cylinder 1 is reduced. The degree of reduction of vacuum in the vacuum chamber of amplifier 2 is determined by the setting of valve 22. When the signal stops

от датчика 21 система возвращаетс  в исходное состо ние.from sensor 21, the system returns to its original state.

Система (фиг. 2) отличаетс  наличием модул тора 29 давлени , встроенного в трубопровод между главным цилиндром 1 и колесным цилиндром. Модул тор 29 может быть подключен к датчику 21 и срабатывать одновременно с регул тором 7 или с некотором временным разрывом.The system (Fig. 2) is characterized by the presence of a pressure modulator 29 embedded in the pipeline between the master cylinder 1 and the wheel cylinder. The modulator 29 can be connected to the sensor 21 and operate simultaneously with the controller 7 or with a certain time gap.

В системе (фиг. 3) усилитель 2 подключен через регул тор 7 к компрессору 30, а в регул торе 7 вместо обратного клапана 22 выполнен регулируемый дроссель 31, образованныйIn the system (FIG. 3), the amplifier 2 is connected via regulator 7 to compressor 30, and in regulator 7, instead of the check valve 22, an adjustable choke 31 is formed, formed

Регул тор 7 (фиг. 4) выполнен с пневмоуправл емым двухседельным клапаном , состо щим из штока 33 с клапанньп 1И дисками 34 и 35, взаимодействующими с седлами 36 и 37. Диск 34The regulator 7 (Fig. 4) is made with a pneumatically controlled double seat valve consisting of a stem 33 with valve 1I discs 34 and 35, which interact with seats 36 and 37. Disc 34

нормально прижат к седлу 36 пружиной 38.Шток 33 св зан с диафрагмой 39, отдел ющей в корпусе 8 камеру 40, сообщенную с входным каналом 14 электромагнитного клапана, в котором канал 15 сообщен с атмосферой, а канал 16 - с источником вакуума. Диск 35 предназначен дл  разделени  каналов 41 и 42, которыми рег-ул тор 7 включен в магистраль 5, а диск 34 - дл  разделени  канала 42 и дополнительного атмосферного канала 43, в котором выполнен регулируемый дроссель 31.the spring 38 is normally pressed against the seat 36. The rod 33 is connected to the diaphragm 39, which separates the chamber 40 in the housing 8 and communicates with the inlet 14 of the solenoid valve, in which the channel 15 is in communication with the atmosphere, and the channel 16 with a vacuum source. The disk 35 is designed to separate the channels 41 and 42, with which the regulator 7 is included in line 5, and the disk 34 to separate the channel 42 and the additional atmospheric channel 43, in which an adjustable choke 31 is made.

При подаче напр жени  на катушку 19 от датчика 21 диск 10 отрываетс  от седла 12, а диск 11 садитс  на седло 13. Камера 40 через каналы 14When voltage is applied to the coil 19 from the sensor 21, the disk 10 is detached from the saddle 12, and the disk 11 sits on the saddle 13. The camera 40 through the channels 14

и 16 сообщаетс  с источником вакуума . Диафрагма 39 прогибаетс  вверх, при этом диск 34 отрываетс  от седла 36, а диск 35 садитс  на седло 37. Канал 42 изолируетс  от канала 41 иand 16 communicates with a vacuum source. The diaphragm 39 bends upward, with the disk 34 detached from the saddle 36, and the disk 35 sits on the saddle 37. The channel 42 is isolated from the channel 41 and

сообщаетс  через канал 43 с атмосферой . В результате разр жение в вакуумной камере усилител  2 уменьшаетс  . Так как проходные сечени  седел 12 и 13 меньше, чем проходные сечени  седел 36 и 37, электромагнит может быть выполнен менее мощным, чем в системе (фиг. 1 и 2).communicates via channel 43 to the atmosphere. As a result, the vacuum in the vacuum chamber of the amplifier 2 is reduced. Since the flow areas of the saddles 12 and 13 are smaller than the flow areas of the saddles 36 and 37, the electromagnet can be made less powerful than in the system (Figs. 1 and 2).
