Изобретение относитс к транспортной технике и может быть использовано в качестве устройств, облегчающих эксплуатацию и техническое обслужива- ние самоходных машин, преимущественно тракторов.The invention relates to a transport technique and can be used as devices that facilitate the operation and maintenance of self-propelled machines, mainly tractors.

Известен сигнализатор бокового опрокидывани транспортного средства, содержащий датчик угла наклона, под- «Q ключенныйк одному из входов одного из сумматоров,к другому входу которого подключен выход другого сумматора, а к выходу - вход порогового блока, соединенного выходом с сигнальным элементом i . A known vehicle lateral tilting detector contains a tilt angle sensor connected to one of the inputs of one of the adders, the output of the other adder is connected to another input, and the input of the threshold unit connected to the signal element i is connected to the output.

Цель изобретени - повышение эффективности работы.The purpose of the invention is to increase work efficiency.

Эта цель достигаетс тем, что сигнализатор снабжен датчиками вертикальных ускорений задних колес трансПОРТНОГО средства и подключенным к 30This goal is achieved by the fact that the detector is equipped with sensors of vertical accelerations of the rear wheels of the transport means and connected to 30

ним узкополосным усилителем, выходы которого соединены со входами второго сумматора.It narrowband amplifier, the outputs of which are connected to the inputs of the second adder.

На чертеже изображена блок-схема устройства.The drawing shows a block diagram of the device.

В устройство вход т датчик 1 вертикальных ускорений правого Зсщнего колеса и датчик 2 вертикальных ускорений левого заднего колеса (которые могут быть установлены, например, на чулках осей), соединенные с двухкаскадным узкополосным усилителем 3, исключающим, высокочастотные помехи (от датчиков сумматора), выходы которого соединены со входами сумматора 4, выход которого соединен с первым входом сумматора 5, второй вход которого -соединен с выходом уси.лител 6 угла наклона, к.которому подключен датчик 7 угла наклона. Выход упом ну того сумматора 5 соединен со входом порогового блока 8, соединенного с сигнальным элементом 9.The device includes a sensor 1 of the vertical acceleration of the right wheel and a sensor 2 of the vertical accelerations of the left rear wheel (which can be installed, for example, on stockings of axles) connected to a two-stage narrow-band amplifier 3, excluding high-frequency noise (from the totalizer sensors), outputs which is connected to the inputs of the adder 4, the output of which is connected to the first input of the adder 5, the second input of which is connected to the output of the tilt angle 6, to which the tilt angle sensor 7 is connected. The output of the adder 5 is connected to the input of the threshold unit 8 connected to the signal element 9.

Claims

The narrowband amplifier can be performed on the integrating amplifier and its bandwidth should be determined by the moment of inertia of the vehicle through the side axis of the tipper. The principle of operation of the device is as follows. Signals from sensors 1 and 2 of vertical accelerations of the rear right and left wheels, passing a two-stage narrowband amplifier 3, arrive at the first and second inputs of adder 4, the output of which is a signal of the Basis from the values that determine the correct torque. The received signal arrives at the first input of the adder 5, and at its second input, the signal from the amplifier 6 of the tilt signal amplifies, which amplifies the output signal from the sensor 7. Received: the resulting signal, representing a cy acyy difference signal and a signal about the static tilt , enters the input of the threshold unit 8. In case the resulting signal at the input of this unit exceeds the response threshold, which is set depending on the parameters of the transtyrtny vehicle (tractor), then it includes a signal element 9, the signal being given the earlier, the higher the level of angular oscillations. Thus, in contrast to the known, the device allows speeding up. the possibility of determining hazardous situations associated not only with the static inclination of the vehicle but also with its angular oscillations. Claims of the lateral tip-over alarm device; nor a vehicle, mainly a tractor, containing a tilt angle sensor connected to one of the inputs of one of the adders, to another input of which another output of the adder is connected, and to the output an input of a threshold unit connected to the output with a signal element characterized in work efficiency, it is equipped with sensors of vertical acceleration of the rear wheels of the vehicle and a narrow-band amplifier connected to them, the outputs of which are connected to the inputs of the second adder.
