Изобретение относитс к области машиностроени , в частности к автомобильному машиностроению.The invention relates to the field of mechanical engineering, in particular to automotive engineering.
Известно приводное устройство дл дискового тормоза, преимушественно, колес автомобил , содержаш,ее кольцевой пневмоцилиндр , размеш енные в нем и изолированные друг от друга кольцевые поршни и поджимаюшую последние пружину .It is known drive device for disc brakes, mainly, of automobile wheels, containing its annular pneumatic cylinder, annular pistons placed in it and insulated from each other and the spring pressed against the latter.
Цель изобретени - сокращение габаритов устройства.The purpose of the invention is to reduce the size of the device.
Дл этого в предлагаемом приводном устройстве дл дискового тормоза один из кольцевых поршней выполнен охватывающим другой кольцевой поршень, при этом охватываемый поршень расположен аксиально подвижно внутри охватывающего с образованием двух кольцевых полостей: одной - напорной, а другой - дл размещени пружины.For this purpose, in the proposed disc brake actuator, one of the annular pistons is made to enclose the other annular piston, wherein the male piston is axially movable inside the female with the formation of two annular cavities: one - pressure, and the other - to accommodate the spring.
Кольцевые полости могут быть изолированы одна от другой с помощью уплотнений .The annular cavity can be isolated from one another by means of seals.
Охватывающий кольцевой поршень может иметь канал, соедин ющий кольцевую полость, в которой расположена пружина, с атмосферой.The annular piston may have a channel connecting the annular cavity in which the spring is located with the atmosphere.
Охватываемый кольцевой поршень иметь хвостовик в виде кольца дл передачи усили на диски тормоза.The annular piston to be covered has a shank in the form of a ring for transmitting force to the brake discs.
Хвостовик может быть снабжен уплотнением .The shank can be provided with a seal.
Устройство может иметь вторую напорную камеру, образованную внутренними стенками кольцевого цилиндра и наружной торцовой стенкой охватывающего поршн .The device may have a second pressure chamber formed by the inner walls of the annular cylinder and the outer end wall of the female piston.
На чертеже показано предлагаемое приводное устройство.The drawing shows the proposed drive device.
Ось 1 автомобил несет на подшипниках 2 втулку 3, на которой посредством болтов 4 и гаек 5 укреплено колесо. Винты 6 сосдин ют тормозные диски 7 и 8 с втулкой 3. Неподвижна часть тормоза состоит из тормозных колец 9 и 10 с наход щимис при торможении во фрикционном замыкании с вращающимис тормозными дисками 7 и 8The vehicle axis 1 carries a bearing 3 on bearings 2, on which a wheel is fixed by means of bolts 4 and nuts 5. Screws 6 brake discs 7 and 8 with sleeve 3. The stationary part of the brake consists of brake rings 9 and 10 with braking friction locking with rotating brake discs 7 and 8
тормозными накладками 11 и 12, которые аксиально подвижно и жестко радиально повещены на укрепленной посредством винтов 13 на осевом фланце 14 тормозной консоли 15. Между тормозными кольцами 9 иbrake linings 11 and 12, which are axially movable and rigidly radially mounted on the brake console 15 fixed by means of screws 13 on the axial flange 14. Between the brake rings 9 and
10 расположен кольцевой тормозной цилиндр 16, в котором аксиально подвижно расположен уплотненный посредством уплотнительных колец рабочий тормозной поршень 17, в полости которого аксиально подвижно расположен подпружиненный тормозной поршень 18 и жестко св занное с ним взаимодействуюшее с тормозным кольцом 10 нажимное кольцо 19.10 there is an annular brake cylinder 16 in which the working brake piston 17 is sealed axially movably by means of sealing rings, in which cavity a spring-loaded brake piston 18 and a pressure ring interacting with the brake ring 10 rigidly connected with it are axially movable.
Расположенна между кольцевым цилиндром 16 и кольцевым поршнем 17 кольцева камера 20 св зана с тормозным клапаном 21 автомобил .Located between the annular cylinder 16 and the annular piston 17, the annular chamber 20 is connected to the brake valve 21 of the automobile.
Предусмотренна дл работы тормоза пружина 22 расположена в полости рабочего тормозного поршн 17 в камере, образованной дном этого поршн и подпружиненным поршнем 18. Между поршнем 17, нажимным кольцом 19 поршн 18, дном поршн 17 и поршнем 18 находитс кольцева камера 23, котора через магистраль 24 и через ограничиваюший давление клапан 25 св зана с клапаном 26 ручного тормоза .The spring 22 provided for the operation of the brake is located in the cavity of the working brake piston 17 in the chamber formed by the bottom of this piston and the spring-loaded piston 18. Between the piston 17, the pressure ring 19 of the piston 18, the bottom of the piston 17 and the piston 18 there is an annular chamber 23, which through line 24 and through the pressure limiting valve 25 is connected to the handbrake valve 26.
Устройство работает следуюшим образом .The device works as follows.
При приведении в действие тормозного клапана 21 автомобил в кольцевую камеру 20 поступает воздух. Нарастаюшее при этом давление движет с одной стороны кольцевой поршень 17 вместе с кольцевым поршнем 18 и взаимодействуюшим с нажимным кольцом 19 тормозным кольцом 10 и тормозной накладкой 12 к врашающемус тормозному диску, и с другой стороны движет кольцевой цилиндр 16 с тормозным кольцом 9 и тормозной накладкой 11 к вращаюшемус тормозному диску 7.When actuating the brake valve 21 of the car in the annular chamber 20 enters the air. The pressure increasing at that moves on one side the annular piston 17 together with the annular piston 18 and the brake ring 10 interacting with the pressure ring 19 and the brake lining 12 to the braking disc, and on the other hand the annular cylinder 16 moves with the brake ring 9 and the brake lining 11 to rotating brake disc 7.
Дл приведени в действие сто ночной тормозной установки или же дл ступенчатого приведени вспомогательной тормозной установки клапан 26 ручного тормоза устанавливаетс в соответствуюшее положение .In order to actuate the one-hundred-night brake installation, or else to step-up the auxiliary brake installation, the handbrake valve 26 is set to the appropriate position.
При этом имеюшеес во врем нормальной работы, а также при приведении рабочего тормоза в камере 23 давление сбрасываетс через отверстие в камере 23 так, что нат жение пружины 22 с одной стороны движет кольцевой поршень 18 с нал имным кольцом 19, тормозным кольцом 10 и накладкой 12 к тормозному диску 8 и с другой стороны кольцевой поршень 18 движетс к кольцевому цилиндру 16, который продолжает это движение вместе с тормозным кольцом 9 и накладкой 11 к тормозному диску 7.At the same time, during normal operation, as well as when the service brake is brought in chamber 23, pressure is released through an opening in chamber 23 so that tension of spring 22 on one side moves ring piston 18 with hydraulic ring 19, brake ring 10 and lining 12 to the brake disc 8 and on the other hand, the annular piston 18 moves to the annular cylinder 16, which continues this movement together with the brake ring 9 and pad 11 to the brake disc 7.
Изобретение позвол ет значительно сократить габариты приводного устройства.The invention makes it possible to significantly reduce the dimensions of the drive device.
