Description

SK 5100 Υ1

Technical field

The technical solution relates to a device for tilting the car in the direction of a bend and to maintain the transverse plane of the car in case of uneven road surfaces.

BACKGROUND OF THE INVENTION

Until now, much weight has not been placed to compensate for the centrifugal and gravitational forces acting on the driver and vehicle occupants in bends and road unevenness. The reason is to provide sufficient comfort through ergonomic seats, suspension suspension and increased vehicle weight. We bend the cars in the bend to the outside, ie centrifugal forces and transverse slopes in the case of uneven road surfaces, or gravitational forces, not only cause discomfort but also reduce the stability and thus the safety of the vehicle. It also neglects the enjoyment of driving a car that tends to tilt the body in the direction of the bend, thereby leveling and grounding any unwanted forces that are outside the gravity axis acting on the vehicle occupants.

The essence of the technical solution

The above-mentioned deficiencies are largely eliminated by a vehicle tilting device consisting of a chassis, front and rear axle, suspension and body with associated hydraulic system, processor control system and centrifugal force and gravity sensor, and a tilt position sensor based on the hydraulic system it consists of a pair of hydraulic cylinders associated with each axle of the vehicle. The rollers are located between the upper end of the spring body and the body support points. The rollers are connected to the spring body via a connecting element which allows the original height of the vehicle to remain unchanged with the attachment. The discharge part of the cylinders of the front and rear axles is individually connected to rotary pumps working on a common shaft. The lower parts of the cylinders of each axle are interconnected. The servomotor with brake drives both pumps simultaneously. The servomotor is monitored via a processor connected to a centrifugal force sensor and a vehicle tilt position sensor. Using signals from both sensors, the processor processes a signal for running the servomotor driving both pumps simultaneously.

Operation of the device is that when the sensor detects centrifugal force, it generates a signal that the processor compares to the magnitude of the signal from the position sensor. If there is a difference between the signals then the processor activates the operation of the servomotor driving the pumps. The direction of rotation of the motor is to the side from which the sensor has detected the force. When equality of the two signals is reached, the servomotor stops running with the resultant inclination of the car corresponding to the size of the measured signal. The ratio between signal size and tilt can also be manually adjusted. Fast repeating signals are averaged by the processor, or frequent small signals are neglected.

The tilt device is energy-efficient because the weight of the vehicle keeps the hydraulic cylinders under constant pressure and only deviations from this equilibrium pressure state are corrected by a pump system whose energy consumption is low. If the pumps are set to a certain degree of freedom, it is also possible to use a hydraulic connection between the left and right sides of the car to compensate for suspension, replacing the typical balancing shaft. The tilt device does not represent major structural changes to a conventional car and provides greater safety at increased speed as well as increased driving pleasure.

Examples of technical solution

Fig. 1. illustrates a vehicle tilting device which is an additional or original device for a car with a chassis, front and rear axle, suspension and bodywork. The vehicle tilting device is composed of hydraulic cylinders 1 located between the upper end of the tongues 2 and the body support points 3. The pump system consists of a motor 4 with an electromagnetic brake 5 and two rotary pumps 6a 7 connected to the motor 4 and operating on a common control . A pump 6 is provided for the front axle cylinders and a pump 7 for the rear axle cylinders. When changing the direction of rotation of the engine 4 and the pumps 6 and 7, the left or right cylinders 1 are inflated causing the car to tilt to one side or the other. Front and rear cylinders2

SK 5100 Υ1 right must be powered separately to avoid connecting the front and rear axles. The centrifugal forces O and gravity forces G are recorded by the acceleration sensor 8, whose signal is transferred to the processor 9. The processor 9 compares the signal from the sensor 8 to the signals PI and P2 of the feedback sensor 10, and their correspondence indicates the appropriate vehicle inclination, including gravity. Matching signals from 8 and 10 stops the next tilt or leveling the car. The magnitude of the centrifugal and gravity signal from the sensor 8 is proportional to the inclination of the car. The proportion between signals 8 and 10 is adjustable. The processor 9 generates the direction of rotation and the length of the motor 4 from the signals of the sensor 8 and the feedback 10 by means of current inputs M1 and M2. The brake 5 on the motor 4 fixes a certain position of the pumps 6 and 7, which also fixes the inclination of the vehicle. The brake 5 can also be replaced by a set of inlet and outlet valves from pumps 6 and 7. The pumps 6 and 7 are connected to the upper part of the cylinders 1, the lower part being connected from cylinder to cylinder. With this, the position of the piston in the cylinder 1 is fixed in a position dependent on the filling and emptying functions of the pumps 6 and 7. Due to the lack of vertical space under the bonnet, the cylinders 1 are offset parallel to the tongues 2 by interconnection 11lly held by a member 12 in the body structure .

Fig. 2 illustrates an inductive acceleration sensor consisting of a vehicle speed sensor 22 and a directional displacement sensor 23 and a processor 24. Using the speed and twist radius parameters, the processor 24 generates a relative indication of the magnitude of the centrifugal force per vehicle. However, the indication is without a gravitational signal, which can be supplemented e.g. gyroscopic device.

Fig. 3 shows a pendulum transducer which records both the centrifugal forces 0 and the gravitational forces G. This simple transducer consists of a pendulum mass 25 which rotates about an eccentrically positioned axis 26 and a pulsation damper 27 and a precise potentiometer 28. The centrifugal and gravity forces together deflect the pendulum connected to the pendulum. a precision potentiometer 28 whose reading is proportional to the centrifugal forces O and the gravitational forces G together.

The power consumption of the vehicle tilting equipment is low, because the rollers 1 are under constant pressure by the weight of the vehicle and only deviations from this equilibrium are provided by the pumps.

The device according to this technical solution can be used in mass-produced cars as well as in adaptation of individual cars.

The device also provides the possibility of removing the front equalizing suspension rod, since the shock springs on one side are transmitted to the other via an adjustable hydraulic system.

The tilting device provides greater safety at increased speed as well as driving pleasure
