Device to prevent tipping of the vehicle
(57) Abstract:Device to prevent tipping of the vehicle reduces the risk of overturning of the vehicle, mainly tractors due to the automatic disabling of the ignition system. On the vehicle by means of a spherical joint has a pendulum. When the inclination of the vehicle, the pendulum moves in a corresponding plane and in contact with one of the elements, which opens normally closed contacts and closes the normally open. The contacts are connected in parallel or in series with the power source and with light and sound signals installed on the vehicle. The device allows you to indicate the inclination of the tractor at an angle exceeding a specified until it reaches a critical state. 2 Il. The invention relates to the transport industry, in particular to devices that reduce the probability of rollover of the vehicle (mainly tractors) in the transverse and longitudinal plane due to the automatic ignition is switched off; stops vehicles shall Innovene associated with the rollover of the vehicle injuries and accidents (or the effects of prolonged tilt of the vehicle).A well-known system of automatic stabilization, which is designed to maintain the vertical position of the skeleton of the vehicle.The stabilization system includes: a stabilizer pendulum, Executive cylinders with check valves, faucet off of the stabilization system, the flow divider and control devices.The units of the stabilization system are placed in different areas of transport and interconnected metal pipes and hoses (Xenetic I. P. and others "Tractor MTZ-80, its modifications, M., Agromisa, 1991, S. 266-268).The disadvantages include:
significant system weight is about 15 kg;
the complexity of maintenance due to the fact that added for more hydraulic cylinders, oil lines, distributor, etc.;
the complexity associated with the installation of additional devices (cylinders, distributor, metal lines, and so on);
each transport requires your device.It is known and the other device (SU, and. C. 816849, class B 62 D 49/08), in which to prevent tipping of the vehicle (e.g. tractor) contains a position sensor, filled Tokaido is (for example, generator), the source of the sound and light signal. In addition, the device has an intermediate relays, solenoids, cores are mechanically connected with the pedals clutch in the two shoulders brake levers. In the control circuit relay is installed the switch.But this device is not devoid of drawbacks, among which should be mentioned:
the device used harmful substance - mercury;
the considerable weight of the device, more than 6 kg;
a large number of used electrical appliances (for example, relay and so on);
reduced functionality due to the fact that this device works only in the longitudinal plane or transverse plane;
each transport requires your device.Closest to the invention is a device to prevent tipping of the vehicle containing the upright pendulum, one end of which is pivotally connected with the vehicle can move and opening one and closing the other of the contacts, the latter of which are connected in parallel and in series with the power source and with light and sound signalng of the device is its limited functionality.The technical result, which can be obtained by carrying out the invention, is to expand the functionality of the device by providing a premature disconnection of the ignition systems of the engine and the stop of the vehicle, as well as sound and light alerts the driver about the danger of overturning of the vehicle without driver.All the contacts are arranged in four groups, each of which consists of one pair of normally closed contacts and one pair of normally open contacts, one contact of each pair of normally closed contacts mounted on one side of the rolling element on the other side of which is fixed a plunger, made of dielectric and with the possibility circuit normally open contacts when moving the rolling element caused by interaction with a pendulum associated with the vehicle through the spherical hinge and configured to move in the longitudinal and transverse vertical planes passing through the center of gravity of the vehicle, and interaction with one of the four movable elements, while the normal is the position of the ignition system of the vehicle.In Fig. 1 presents a General view of the device of Fig. 2 - device operation in case of tilt.The device contains 4 of the same design group contact-breaker ignition and alarm (CPSS):
"CPSS" - reverse - "SX", "CPSS" - forward course - "PH", "CPSS" - starboard - "IB", "CPSS" - left side - "LB", "CPSS" is connected through an electrical circuit to a power source (e.g. generator).The pendulum 1, mounted on a vehicle, through the spherical hinge is vertical and has the ability to move when the tilt of the vehicle along the longitudinal and transverse vertical planes passing through the center of gravity of the vehicle.Each group of contacts has one pair of normally closed contacts 2 and 3, and one pair of normally open contacts 4 and 5. One of the contacts of each pair of normally closed contacts mounted on one side of the rolling element 6, on the other side of which is secured the plunger 7, is made of dielectric material and with the possibility circuit normally open contacts 4 and 5 when moving the rolling element 6. When the inclination of the vehicle, the pendulum 1, moving icaet pins 2 and 3 and closes the contacts 4 and 5. Normally closed contacts 2 and 3 of each group are connected in series and serially included in a circuit low voltage ignition system of the vehicle. Normally open contacts 4 and 5 are connected in parallel and connected in series with the power source and with a light 8 and 9 sound signals installed on the vehicle.The device works in the following way (see Fig. 1).When the vehicle ignition system provides a supply of a specified constant voltage "CPSS" - SX, then "CPSS" - LB, then "CPSS" - HRP, then "CPSS" - PB, and further to the internal combustion engine in the vehicle weight.This is achieved by the operation of the internal combustion engine.When the inclination of the vehicle by an angle exceeding specified in either direction, i.e. in the longitudinal or transverse direction (see Fig. 2), the pendulum 1 is in contact with one of the movable elements 6, which provides the unlocking pins 2 and 3. Thereby breaks the circuit to the ignition system of the engine. The vehicle stops. Simultaneously, the pusher 7 closes the contacts 4 and 5 and on the private funds containing the roll sensor associated with the vehicle with the possibility of transverse angular deviation from the vertical axis for closing one and opening the other of the contacts included in the circuit, powered by a generator, consistently with sound and light alarm, characterized in that the tilt sensor is a pendulum rod with a weight at the end, pivoted at the center of gravity of the vehicle with the additional possibility of longitudinal angular deviations for contact with the contacts located around the pendulum rod.
