A first spur gear is mounted on the first transmission shaft, and a second spur gear is mounted on one end of the second transmission shaft. The first spur gear meshes with the second spur gear, and the first spur gear and the second spur gear mesh with each other, forming a first transmission. The shaft is connected to the second transmission shaft. At the other end of the second transmission shaft is an eccentric gear. The eccentric gear has a sliding groove.The upper end of the fork stem is pivotally connected to the drive wheel. The drive wheel is secured to one end of the second transmission shaft. When the eccentric wheel rotates in its groove, the drive wheel is driven, and the simulator is located at the lower end of the fork stem. A strain gauge is mounted on the fork stem and connected via a wire to the data acquisition and control module.

[0005] The disadvantage of the analogue is that the analogue is designed for a driving simulator and cannot be used for a real vehicle, therefore it cannot reduce the likelihood of a vehicle overturning when turning.

[0023] Fig. 4 shows the steering system, rear view. Fig. 5 schematically shows the connection of components to the steering system.

[0024] The following are indicated on the figures: 1 - upper block, 2 - front bracket, 3 - rear bracket, 4 - side plate, 5 - spring, 6 - bushing, 7 - lock, 8 - tilt limiter, 9 - cable, 10 - strain gauge, 11 - tilt angle sensor, 12 - electronic control unit, 13 - high-speed drive, 14 - steering wheel, 15 - strap, 16 - shaft, 17 - steering arm, 18 - steering rod, 19 - suspension, 20 - skis, 21 - lower block, 22 - snowmobile body, 23 - track, 24 - snowmobile engine, 25 - track suspension system.

[0025] The present group of inventions is implemented by means of the following technical means.

[0026] This steering rack is designed for installation in the steering system of the following vehicles: snowmobile, swamp vehicle, ATV, tricycle, buggy, all-terrain vehicle and jet ski.

[0027] The steering column comprises a handlebar 14 with a strap 15 mounted to it, and an upper block 1 is attached to the handlebar 14, for example by bolting or welding. The upper block 1 is connected to a lower block 21 and is also connected to a shaft 16 configured to transmit reciprocating motion from the handlebar 14 to a steering arm 17, which in turn transmits reciprocating motion to steering rods 18, and the steering rods 18 transmit reciprocating motion to the skis 20.

[0028] The upper block 1 and the lower block 21 are made U-shaped, with cuts made on the ends of the blocks, and lugs with through holes made on the sides.

[0029] The upper block 1 and the lower block 21 are pivotally connected to the front bracket 2 and the rear bracket 3 by means of bushings 6. The front bracket 2 and the rear bracket 3 are connected to each other by a side plate 4, on the sides of which there are lugs having through holes.

[0030] To the upper block 1 and the lower block 21, on both sides, tilt angle limiters 8 are mounted, designed with the possibility of determining the end positions of the steering wheel and the end positions of the sensors (tilt angle sensor 11 and strain gauge 10), and also designed with the possibility of adjustment.

[0031] Film strain gauges or wire strain gauges, or foil strain gauges, or semiconductor strain gauges, or resistive strain gauges, or strain gauges can be used as strain gauges 10.

[0032] Gyroscopic sensors, or ultrasonic sensors, or optical sensors, or magnetic sensors, or inclinometric sensors, or accelerometric sensors can be used as tilt angle sensors 11.

[0033] In the front bracket 2, openings are made, inside of which a retainer 7 is mounted, and the retainer 7 is pivotally connected to the rear bracket 3. The retainer 7 is designed with the possibility of fixing inside the cuts made in the upper block 1 and the lower block 21, as a result of which the fixation of blocks 1 and 21 occurs.

[0034] Springs 5, configured as pre-stressed compression springs, extension springs, torsion springs, or electromagnetic springs, are mounted in through-holes made in the eyes of the upper block 1 and lower block 21, and the side plate 4. Springs 5 ​​are configured to return the housing of block 1 to its original position. Also mounted in the through-holes is a cable 9, configured to mechanically connect block 1 or 21, or blocks 1 and 21, and skis 9.Also, in the through holes, opposite the springs 5, the terminals of the strain gauge 10 are connected, which is configured to measure the force of the driver's action on the steering wheel 14 and transmit the measured values ​​to the electronic control unit 12, also connected are the terminals of the tilt angle sensor 11, which is configured to measure the angle of deviation of the steering wheel from the initial position, as well as to measure the rate of change of the angle of deviation of the steering wheel from the initial position and transmit the measured values ​​to the electronic control unit 12, and the electronic control unit 12 is configured to generate a control signal for the high-speed drive 13, mounted in the suspension 19, wherein the high-speed drive 13 is configured to provide desynchronized control of the suspension 19.

[0035] The suspension 19 is made in the form of a telescopic suspension or in the form of a lever suspension, wherein the suspension 19 contains an elastic element, for example a spring or leaf spring, or a shock absorber.

[0036] A protective casing can be mounted on top of the control column, and the casing can be made of a metal alloy and / or plastic, and / or polymer composition, and / or composite composition, and / or wood.

[0037] Thus, for example, this steering rack can be mounted on a snowmobile (Fig. 2), containing a snowmobile engine 24, a snowmobile body 22, including a snowmobile frame, a suspension 19, skis 20, a track belt 23, mounted on a track suspension system 25.

[0038] Snowmobile steering rack operating algorithm:

[0039] Sensors (a strain gauge and a tilt sensor) begin measuring data when the steering wheel is pulled in the direction of roll (for example, when making a right or left turn). They measure the steering wheel force, the steering angle from the initial position, and the speed of the applied force. These measured values ​​are then transmitted to the electronic control unit, which then generates a control signal and transmits it to the suspension via a high-speed actuator, adjusting the suspension stiffness.

[0040] For example, when turning left, the snowmobile driver tilts the steering wheel to the left. The strain gauge measures the force applied to the steering wheel, and the tilt angle sensor measures the steering angle from the initial position and the rate of change. The measured values ​​are then transmitted to the electronic control unit, which then transmits them to the suspension via a high-speed drive. Thus, the suspension mounted on the left side of the snowmobile receives a control signal to soften the suspension stiffness, which reduces the ground clearance on the left side of the snowmobile and decreases lift. Meanwhile, the suspension mounted on the right side of the snowmobile receives a control signal to stiffen the suspension stiffness, which increases the ground clearance on the right side and increases lift. Due to the difference in lift and ground clearance, the snowmobile turns left.After completing the maneuver (turning left), the snowmobile driver straightens the steering wheel, making the suspension stiffness on the right and left equal, the ground clearance and lift also equalize, and the snowmobile continues moving in a straight line.

[0041] Without proper steering, turning a snowmobile in deep snow is accomplished by shifting body weight. This shifting creates a roll (a deviation of the snowmobile's center of gravity from its center of gravity), which requires considerable physical effort. However, since a snowmobile's mass is several times greater than the driver's, turning a snowmobile in deep snow by shifting body weight is only possible with some probability. Turning in deep snow is not always possible. Furthermore, additional resistance to turning by shifting body weight is exerted by the snowmobile's track. Furthermore, if the snowmobile is being steered:

[0042] 1. When the snowmobile driver holds the left handlebar with their left hand and the right handlebar with their right hand, the sensors mounted to the upper unit measure the steering force and steering angle. If the upper unit is in its extreme position (far right or far left) because the tilt limiter prevents further movement, both the upper and lower unit sensors measure the driver's steering force, steering angle, and the rate of change of angle, working together.

[0043] 2. When the snowmobile driver holds the steering wheel handle with one hand and the strap with the other hand, due to the small leverage, the sensors mounted to the upper block are not activated, and the force acting on the steering wheel and the steering wheel angle are measured by the sensors mounted to the lower block.

[0044] For example, when driving along a slope on a snowmobile with a real steering column mounted, the suspension is adjusted in such a way that it becomes possible to move along the slope without using counter-steering, while the real steering column also allows you to avoid counter-steering the snowmobile when turning left / right in deep snow.

[0045] A real steering column mounted on a snowmobile eliminates both countersteering and its main drawback—hitting an obstacle hidden by snow. Such obstacles can include branches, rocks, logs, and so on. When countersteering occurs, the snowmobile tilts, and the ski is pointed in a direction different from the snowmobile's intended direction of travel. The obstacles, hidden beneath the snow, are encountered not with the front of the ski, which has an upward, rounded section designed for overcoming obstacles, but with the side, straight surface of the ski, which is not designed for overcoming obstacles. As a result, the ski, suspension components, and body parts are deformed or damaged when the snowmobile rolls over. This poses a high risk of injury to both the driver and passenger.

[0046] This snowmobile steering rack is designed to operate in three modes:

[0047] 1. All sensors are active.

[0048] 2. The load cells are active and read the force exerted by the snowmobile driver on the steering wheel, and the tilt angle sensor is disabled / inactive, while the upper block or the lower block is mechanically locked using a clamp.

[0049] 3. The system is inactive, the load cell is disabled / inactive, the tilt sensor is disabled / inactive, while the upper block and the lower block are mechanically locked using a latch.

[0050] An example of the invention.

[0051] In the embodiment, the upper block, front bracket, rear bracket, side plates, lower block, clamps, parts of the upper and lower blocks were made of an alloy having the following composition (Table 1):

[0052] Table 1 - Alloy composition.

[0053] This alloy was used in the form of sheets with a thickness of 3 mm and 6 mm, from which these parts were cut out using laser cutting on an OREE LASER FM3015A Raycus 6000 W fiber laser cutting machine, after which the edges of each part were processed on a GC-16 belt grinder using an abrasive belt made of BAZ TD-25363 with a grain size of P100.

[0054] In this case, the parts have the following dimensions (Table 2):

[0055] Table 2 - Dimensions of parts.

[0056] In this case, the front and rear brackets have holes with a diameter of 25 mm, designed to allow connection with the bushing.

[0057] Also, on a similar machine OREE LASER FM3015A Raycus 6000 W, parts for the upper and lower blocks were cut out, which were then welded together.

[0058] An extension spring (up to 100 kg, with dimensions 3*23*95) was used as a spring.

[0059] The bushing is made of polyamide, namely PA 66-LG-10 TU 6-06-134-2016, the granules of which were pre-sintered into a single cylinder, cooled under vacuum, after which the cylinder was turned on a REALREZ SK0640 CNC lathe to the following dimensions: bushing diameter - 25 mm, and bushing thickness - 5 mm.

[0060] The side bracket was drilled with 26 holes of 4mm diameter.

[0061] The tilt limiter is made in the form of a rod with a heel, 10 cm long, on the outer surface of which an MB thread is cut and 4 MB nuts welded together.

[0062] The cable is made in the form of a metal multi-strand cable, 1.5 meters long, and the cable has a rubberized coating.

[0063] The K-R16G was used as a strain gauge.

[0064] ESCORT DU-BLE was used as an inclination angle sensor.

[0065] An Arduino Nano 22 BLE rev2 was used as an electronic control unit.

[0066] The high speed drive used was 45200-02211 Toyota.

[0067] Thus, the front and rear brackets were connected via holes drilled in the side plate, namely, by bolts. The upper and lower blocks were mounted to the front and rear brackets using bushings. K-R16G strain gauges and ESCORT DU-BLE tilt angle sensors were mounted to the eyes of the upper and lower blocks. Extension springs were mounted between the eyes of the upper block, lower block, and side plate, and a cable was mounted between the eye of the side plate and the lower block. Tilt limiters were mounted on both sides of the upper and lower blocks.

[0068] The corresponding functions of the electronic control unit were programmed using Python. Below is a part of the code that demonstrates the basic logic of work (describing the full source code does not make much sense): import rospy from sensor msgs.msg import Joy from std msgs.msg import Float32 class SnowmobileControl: def init (self): self.left force = 0.0 self.right force = 0.0 self.left angle = 0.0 self.right angle = 0.0 self.left_force_pub = rospy.Publisher(71eft_force', Float32, queue_size=10) self.right_force_pub = rospy.Publisher(7right_force', Float32, queue_size=10) self.left_angle_pub = rospy.Publisher(71eft_angle', Float32, queue_size=10) self.right_angle_pub = rospy.Publisher(7right_angle', Float32, queue_size=10) rospy.Subscriber(7joy', Joy, self.joy callback) def joy_callback(self, data): if data.axes[0] != 0.0 and data.axes[l] != 0.0:

[0069] # Using sensors mounted to the upper block self.left force = # read left force from sensor mounted to upper block self.right force = # read right force from sensor mounted to upper block self.left angle = # read left angle from sensor mounted to upper block self.right angle = # read right angle from sensor mounted to upper block else:

[0070] # Using sensors mounted to the lower block self.left force = # read force from sensor mounted to lower block self.right force = # read force from sensor mounted to lower block self.left angle = # read angle from sensor mounted to lower block self.right angle = 0.0 self.left_force_pub.publish(self.left_force) self.right_force_pub.publish(self.right_force) self.left_angle_pub.publish(self.left_angle) self.right_angle_pub.publish(self.right_angle)

[0071] The embodiment described above was mounted on a BRP Lynx 69 Yeti 600 ACE snowmobile; accordingly, the steering wheel, strap, shaft, steering arm, steering rod, and skis were the parts supplied with the snowmobile by the manufacturer.

[0072] At the same time, the standard suspension from the BRP Lynx 69 Yeti 600 ACE snowmobile was modified as follows: the travel of the suspension rods was increased, and the suspension stiffness control unit was also modified.

[0073] The steering system described above was mounted between the shaft and the steering wheel by means of a bolted connection, and the installation was carried out in compliance with the following rules: relative to the steering wheel, the steering system should be at an angle of 90 degrees (error of 10 ± 5 minutes), and relative to the shaft, the system should be at an angle of 0 degrees (error of 5 ± 3 minutes).

[0074] After which a series of tests were carried out on the snowmobile, namely 10 turns were made at each of the following angles: 30 degrees, 45 degrees, 60 degrees, 90 degrees, and a U-turn (180 degree turn).

[0075] Below in Table 3 are presented statistics on the rollover of a vehicle, namely a BRP Lynx 69 Yeti 600 ACE snowmobile, without the present invention and with the present invention mounted.

[0076] Moreover, the speed of entering the turn was approximately the same each time (from 43 km / h to 46 km / h).

[0077] Each of the turns was 100 meters long.

[0078] Table 3 - Number of vehicle rollovers during a turn of a given degree.

[0079] Moreover, the present invention was also tested on a swamp buggy.

[0080] Specifically, the actual device was mounted in the steering column of the AG-20 all-terrain vehicle, and a system for forced twisting of the frame relative to the horizontal axis of rotation was used as a high-speed drive.

[0081] The combined effect of this system and the forced twisting of the frame relative to the horizontal axis of rotation results in a "walking" swamp vehicle while riding, allowing the vehicle to easily navigate peat pits and swamps.

[0082] Experiments with the prototype showed that the number of vehicle rollovers during a 30-degree turn decreased from 3 times out of 10 to 0 times out of 10, the number of vehicle rollovers during a 45-degree turn decreased from 5 times out of 10 to 1 time out of 10, the number of vehicle rollovers during a 60-degree turn decreased from 5 times out of 10 to 1 time out of 10, the number of vehicle rollovers during a 90-degree turn decreased from 7 times out of 10 to 2 times out of 10, and the number of vehicle rollovers during a 45-degree turn decreased from 8 times out of 10 to 2 times out of 10, that is, the present invention reduces the likelihood of vehicle rollover during a turn by at least 3 times.The need for this group of inventions lies in the fact that the use of vehicles for movement on terrain not equipped with asphalt pavement or other pavement suitable for safe driving carries the risk of injury, mutilation, sometimes, unfortunately, incompatible with life, the present group of inventions is designed to reduce the likelihood of these incidents, both for use by beginners (people who are just beginning to comprehend the path of off-road driving), and for professionals.

[0083] Thus, due to the fact that the vehicle steering system, comprising a front bracket, a rear bracket, an upper block, a lower block, side plates, strain gauges, an inclination sensor, an electronic control unit, a high-speed drive and a suspension, wherein the upper block and the lower block, made U-shaped, are pivotally connected to the front bracket and the rear bracket by means of bushings, and the front bracket and the rear bracket are connected to each other by means of side plates, wherein the strain gauges and inclination sensors are mounted both to the upper block and to the lower block, also the strain gauges and inclination sensors are connected to the electronic control unit, configured to generate a control signal for controlling the high-speed drive, configured to control the suspension, in addition, due to the fact that the steering column of the vehicle with the steering system, containing a steering wheel, a shaft, a steering rod,a front bracket, a rear bracket, an upper block, a lower block, side plates, a strain gauge, a tilt angle sensor, an electronic control unit, a high-speed drive and a suspension, characterized in that a steering wheel connected to the upper block, and the lower block is connected to a shaft, wherein the upper block and the lower block, made U-shaped, are pivotally connected to the front bracket and the rear bracket by means of bushings, and the front bracket and the rear bracket are connected to each other by means of side plates, wherein the strain gauges and tilt angle sensors are mounted to both the upper block and the lower block, also the strain gauges and tilt angle sensors are connected to the electronic control unit, configured to generate a control signal for controlling the high-speed drive, configured to control the suspension, and the shaft is connected to the steering rods by means of a steering knuckle, in addition due to the fact that,that a snowmobile with a steering column and a steering system, comprising a steering wheel, a shaft, a steering rod, a front bracket, a rear bracket, an upper block, a lower block, side plates, a strain gauge, a tilt angle sensor, an electronic control unit, a high-speed drive and a suspension, characterized in that the steering wheel is connected to the upper block, and the lower block is connected to the shaft, wherein the upper block and the lower block, made U-shaped, are pivotally connected to the front bracket and the rear bracket by means of bushings, and the front bracket and the rear bracket are connected to each other by means of side plates, wherein the strain gauges and tilt angle sensors are mounted both to the upper block and to the lower block, also the strain gauges and tilt angle sensors are connected to the electronic control unit, configured with the possibility of generating a control signal for controlling the high-speed drive, configured with the possibility of controlling the suspension,and the shaft is connected to the steering rods by means of a steering knuckle, which provides the technical result of reducing the likelihood of the vehicle overturning when turning.
