The mechatronic system for increasing the drag force in the trailer is an invention in the field of the automobile transportation industry and speed reduction equipment independent of brake -retarder and intarder- especially with the possibility of being independent of the trailer tractor. In this invention, an attempt has been made to solve the problem of reducing the speed of trailers on the slope of the road without using brakes. In the existing inventions, the problem of speed reducers is the increase in temperature and pressure on the gearbox and the tractor engine, which, in addition to generating unwanted heat, has the risk of a rotating collision between the trailer and the tractor (jackknife). These problems will be solved by applying traction force from the trailer and reducing the speed of the wheels. To reduce the temperature, the turbine cooler is used, which is circulated by the hydraulic force lost in the reducer.

One of the problems in trailers is the reduction of speed on the slopes of the road without using the brakes and the increase in temperature due to the use of heavy gears or retarders and intarders. Also, the application of restraining force on the tractor leads to the risk of the trailer colliding with the truck. This invention has minimized this problem by placing the hydraulic speed reducer on the trailer wheels equipped with the turbine air blower.

Solution of problem

To solve the problem of speed control in the slope for trailers (1) independently of the tractor cooling (2), we have used the hydraulic limiter (5). The electronic controller (4) provides the best slip control during operation. The wheel (3) does not have many changes and includes a metal ring (16) equipped with turbine grooves (22). These turbine grooves (22), which are made by making diagonal cuts along it, cause the air to be drawn from the center and the brake disc (12) to the outside during the rotation of the wheel (3). Due to the increase in the temperature of the brake discs (12) due to friction, a reduction of the temperature always seems necessary. The main reason for placing two disks (12) next to each other is the passage of air through the space between them and increasing cooling. A rubber tire (6) is placed around the ring (16), which maintains the distance between the metal ring (16) and the ground by compressed air. The ring (16) which is connected to the metal shaft (19) by screws (17) is fixed in place with the help of nuts (18). The wheel suspension system is of the air balloon type (7) to provide the advantage of longer life and greater flexibility.

The metal base (8) is connected to the trailer chassis (1) on one side by the u-bolt (9) and on the other side by the balloon (7). The brake set (11) which includes pads and an ABS sensor uses the hole (14) on the metal base (8) to pass the pipes and communication wires. The metal shaft connection (19) to the base (8) is by roller bearing (13). Roller bearing (13) uses cylindrical shots (20), an outer connection to the base (8), and an internal connection to the shaft (19) to allow circulation around the shaft axis (19). Connection and fixation of the brake disc (12) to the shaft (19) is with the help of screws (21). It should be noted that when braking, a large deterrent force is applied to the discs (12), which, in the event of a weakness in their connection to the wheel axle (19), can cause the screws cut (21) and the reverse circulation of the disc (12). Hydraulic circulation limiter (5) is made of turbines of creating oil pressure and path blockers that will be cooled by the blown air of the wind turbine.

In retarders and intarders, different modes of restrictions seem to be essential. This means that by placing the control knob in different modes, a different amount of deterrent force is available to the driver. The main reason for this choice is the different slopes and load weights and maximum permissible speed on different roads. In this limiter (5), which applies the force with direct connection to each wheel (3), with the help of electric valves (25) the routes are opened or closed. Hydraulic torque limiter (5) includes hydraulic fluid and air turbines. When the wheel axis (15) rotates, the frame (40) connected to it also starts to rotate and the magnets (38) also generate a limited amount of electricity by passing in front of the bobbin (26) so that they supply enough power for starting bobbin (26) as a consumer in the required time. In the starting state, when the electricity enters the bobbin (26), the turbine (28), which was freewheeling, is attracted to the rotating base (27) and starts injecting oil toward the holes (34). In the meantime, the turbine stator (29) creates the first inhibition stage and the narrowed holes (42) create the second hydraulic fluid flow speed reducer.

We will have the highest hydraulic fluid pressure in this part. The liquid under pressure enters the chamber (41) by passing through the hole (42). The design of the hole (42) is made in such a way that there is a narrow area in it, which will cause a decrease in the speed of the liquid. The moving liquid will enter the transfer channel (23) by passing through the turbine blades (34). The transfer channel (23) will be made of an alloy with the ability to withstand hydraulic pressure and suitable heat transfer capability. Considering the function of this piece and its place in this part, the hot hydraulic fluid enters from the chamber (41) to the end of the speed reducer (5), and the rate of its passage will be controlled by electric valves (25). Due to the conductivity of the metal channel (23), the hot fluid heats it and passes through.

To reduce the temperature in this area, we have created a distance between the channels to maximize its contact surface with the pressurized air fluid. It was mentioned that the hydraulic fluid passes through the turbine (34), which is integrated with the ring gear (35). The rotation created in the ring gear (35) is transferred to the solar gear (37) with the help of gears (38) and causes it to rotate at a more rotational speed. In this planetary gearbox, the goal is to increase the number of rounds per unit of time, the result of which is the faster rotation of the fan. The fan (36) is also designed from two parts to create air pressure with different entry angles so that we experience different air passage speeds in different parts. There are more turbine blades around the fan (36) and they inject more air volume and speed than the central part. One of the problems that may arise for the turbine during air suction in this way is the impact of suspended pieces in the air on the turbine blades, which can cause physical damage and partial or total destruction. Also, according to the location of this piece under the car, there is the possibility of suctioning lighter objects from the road surface. To remove this defect, we have used a reticulated protector (32) in front of it that acts like the front of the car window.

The connection of the speed reducer (5) to the wheel (3) and the trailer body (1) will include a fixed connection to the chassis through the base (24) and the hole (43) and the connection by the rotating frame (40). A hollow cylindrical frame (40) is placed on the output shaft of the wheel (15), which, according to the manufacturer's opinion, to prevent these two parts from sliding on each other, protuberances and hollows can be created in the two parts, or the shape can be changed from a circle to other shapes, such as a triangle, square, or polygon. Protuberances and hollows can usually be a thousand thorns or cuts in both pieces, and pressing the wedge is to prevent the freewheeling. The amount of inhibition - which is usually expressed in terms of horsepower - in this system is controlled by the electronic controller (4). Connector (45) is used to feed this module, which is also responsible for transmitting the information. The capacitor number (46) at the input and the electrolyte capacitor (48) at the output of the voltage regulator (47) will be responsible for voltage stability.

The processor (49) that receives the information from the tractor and the wheels through the connectors (45), (50), and (51), after analyzing the data at the outputs of ports B and D with the help of operational amplifiers (53) will control the absorption of the oil pumping rotor turbine (28) and the opening and closing of the electric valves (25). Considering the limited power of the uln2003 amplifier outputs, relays (52) can be used to increase the power and isolate it. To match port A with received inputs, resistors (54) have been used so that high voltage does not damage the port. Two inputs in the connector (45) transfer the information issued from the processor - steering angle, speed and time of opening and closing, and the amount of inhibition - and the brake light of the trailer to this module. The information received in the connector (50) from the right wheels (3) and the connector (51) from the left wheels includes information on rotation speed, temperature, and oil pressure. The outputs in these two connectors have been selected double in some parts, which creates higher security for this sensitive system.

Advantage effects of invention

In this invention, the place of application of reverse propulsion force is transferred to the trailer wheels instead of the gearbox or car engine which was applied to the tractor wheels, and it is desirable to the drivers that will cause trailer and tractor stretching from the rear and we will never have the collision of the two as a result of angle when reduction of speed (jackknife). Also, the air turbine cooler that operates independently of the engine water cooler is another advantage of this invention. Passing the Injected air from the brake disc will reduce the temperature of this point. Providing the required electricity without dependence on tractor electricity is one of the other advantages. Separate control of two rows on the left and right side reduces the slip on the bends. The intensity of deterrence in the downhill will depend on the weight of the load, which is another advantage.
