Description
Изобретение относитс к области автомобилестроени и может быть использовано на транспортных средствах, имеющих :олесный ход, в том числе автомобилей, мотоциклов , самолетов и т. д.The invention relates to the field of automotive industry and can be used on vehicles having: downhill, including automobiles, motorcycles, airplanes, etc.
Известен способ определени блокировки , основанный на сравнении величин, характеризующих процесс торможени 1.A known method for determining the blocking is based on comparing the values characterizing the braking process 1.
Недостатком этого способа вл етс запаздывание опред,елени блокировки.The disadvantage of this method is the delay in detecting a lock.
Целью изобретени вл етс повышение точности определени начала блокировки.The aim of the invention is to improve the accuracy of determining the start of a blockage.
Это достигаетс тем, что одновременно замер ют силу трени в тормозе и тормозную силу и при рассогласовании между ними фиксируют момент начала блокировки.This is achieved by simultaneously measuring the force of friction in the brake and the braking force, and when there is a mismatch between them, the instant of the onset of the lock is recorded.
На фиг. 1 - представлена схема установки тензодатчиков; на фиг. 2 - электрическа схема устройства дл определени блокировки .FIG. 1 - shows the installation of strain gauges; in fig. 2 is an electrical circuit of the device for determining the blockage.
Способ определени блокировки колес транспортного средства заключаетс в том, что одновременно измер ют величину тормозной силы и силу трени в тормозе и по их рассогласованию определ ют момент начала блокировки.The method for determining the vehicle wheel lock is to simultaneously measure the braking force and the friction force in the brake, and determine the starting time of the lock by their mismatch.
Устройство дл реализации способа состоит из установленного на суппорте 1 тензометра 2 и установленного на поворотной цапфе 3 тензометра 4. Тензометры 2 и 4 и резисторы 5 и 6 включены по мостовой схеме.A device for implementing the method consists of a strain gauge 2 mounted on a support 1 and a strain gauge 4 installed on a rotary trunnion 3. The strain gauges 2 and 4 and the resistors 5 and 6 are connected in a bridge circuit.
При торможении возникают сила трени в тормозе, котора передаетс на суппорт 1 и замер етс тензометром 2, и тормозна сила, котора передаетс на деталь подвески - на поворотную цапфу 3 и замер ема тензометром 4.During braking, there is a friction force in the brake, which is transmitted to the caliper 1 and measured by a strain gauge 2, and the braking force that is transmitted to the suspension component is on a swivel pin 3 and measured by a strain gauge 4.
Пока блокировки нет сила трени в тормозе и тормозна сила измен ютс пропорционально , соответственно пропорционально мен ютс .и сопротивлени тензометров, а напр жение между точками 7 и 8 отсутствует .As long as there is no blocking, the friction force in the brake and the braking force change proportionally, and the resistance of the strain gauges change proportionally as well, and the voltage between points 7 and 8 is absent.
При блокировке колеса тормозна сила резко падает, а сила трени в тормозе некоторое врем держитс на прежнем уровне (пока колесо не перестает вращатьс ). Это от.мечаетс тензометрами, происходит разбалансировка моста, а между точками 7 и 8 возникает разность потенциалов, по которой определ ют начало блокировки.When the wheel is locked, the braking force drops sharply, and the friction force in the brake stays at the same level for some time (until the wheel stops rotating). This is indicated by strain gauges, the bridge is unbalanced, and a potential difference arises between points 7 and 8, which is used to determine the start of blocking.
Такой способ позвол ет повысить точность определени момента начала блокировки .This method makes it possible to increase the accuracy of determining the time when the blocking starts.
