Description

The invention relates to the field of vehicles, in particular to methods for increasing the adhesion of the bearing surface of the wheels with the roadway.

There is a method of increasing the coupling properties of a wheeled vehicle, for example, used in the tread of a pneumatic tire containing annular ribs consisting of checker elements in which slit-shaped slots are made. At the depth of the slit-like slot, each surface consists of two sections. The first is made wavy, and the second is flat. On flat sections of the opposite surfaces of the slit-shaped slot, one row of lateral protrusions and reciprocal grooves are arranged with a gap between them (see Patent for invention No. 2589531. Priority date 11/28/2014 Published: July 10, 2016 Bulletin No. 19. Authors : Grigorenko A.V., Andreev M.Yu., Zhogin V.A. Kordiant Open Joint-Stock Company. Open edition).

The known method of increasing the coupling properties of a wheeled vehicle allows, due to the design of the pneumatic tire, namely its tread, to improve the removal of moisture from the contact patch. However, this method has a disadvantage in that when the wheeled vehicle moves along the icy section of the road, the coupling properties of the tire bearing surface with the roadway are significantly reduced, as a result of which a skid can occur, leading to an emergency on the road.

In addition, there is a method of increasing the coupling properties of a wheeled vehicle in the form of a traction device containing levers fixed on a bearing hub, the free ends of which are made with lugs and bent to cover the tire tread, and a device for pressing the levers to the tread in the form of a pressure hub installed coaxially with the bearing hub and associated with it by means of a coupling bolt, wherein the pressure hub is made with a pressure ring with guide elements through which enes levers with radial displacement (see Patent for invention №2023598 Published:.. 30.11.1994 The author Korotenko Open EB edition). This method is selected as a prototype.

The known method allows to increase the adhesion of the wheels when driving on an icy and snowy road in winter. However, when driving in the city, as a rule, in the winter season, road services in places use chemical reagents. In such places, there is no ice cover on the road, and the use of this device can impair the traction of the wheels, the mobility of the car as a whole, and also lead to damage to the roadway.

The objective of the present invention is to improve the coupling properties of the wheels of the vehicle with the roadway, improving the mobility of the car, eliminating damage to the roadway.

The technical result of the proposed invention is to increase the coupling properties of the wheels of the vehicle with the roadway, improving the mobility of the wheeled vehicle, eliminating damage to the roadway.

The technical solution of the proposed invention is to supply the undercarriage of a wheeled vehicle with a device containing an on-board information and control system (hereinafter - CIUS), which connects the actuator with a mechanical coupling and a rotary device with metal chains located on the undercarriage directly near tire drive wheels.

In this case, the method of increasing the adhesion properties of a wheeled vehicle is based on the fact that when the car is moving, the CIUS determines the loss of the adhesion properties of a particular wheel (or wheels in general) with the roadway (their slipping on the moving surface of the roadway) and transmits a signal via electrical wires to an actuating element acting on a mechanical clutch, which mechanically acts on a rotary device with metal chains, pressing it to the contact surface of the wheel. The rotary device is run around the contact surface of the wheel and thereby is driven (rotates), while metal chains rigidly connected to the rotary device under the action of centrifugal forces are unwound to the sides, falling between the contact surface of the wheel and the roadway, thereby increasing the coupling properties .

A method of increasing the coupling properties of a wheeled vehicle, which consists in the fact that using the on-board information and control system a wheel is determined that has lost its coupling properties with the roadway, they transmit a signal from it via electrical wires to the actuator, which acts on the mechanical coupling, by means of which the rotational the device to the side surface of the drive wheel, while using the torque of the drive wheel, a rotational device is driven by which I unwind metal chain in a direction leading directly between wheel and roadway.

The invention is illustrated in FIG. 1, which shows a method of improving the coupling properties of a wheeled vehicle, where: 1 - a machine; 2 - CIUS; 3 - electric wires; 4 - metal chains; 5 - rotational device; 6 - roadway; 7 - actuating element with a mechanical clutch; 8 - a driving wheel; 9 - a running gear.

показано направление вращения металлических цепей 4. Для повышения сцепных свойств колесного транспортного средства, в составе ходовой части 9 машины 1 используется устройство, имеющее в своем составе исполнительный элемент с механической муфтой 7, управляемый по электропроводам 3 БИУС 2. БИУС 2 при движении машины 1 по скользкому дорожному полотну 6 определяет потерю сцепных свойств определенного ведущего колеса 8 (или всех колес) с дорожным полотном 6 и управляет работой исполнительного элемента с механической муфтой 7. При проскальзывании ведущего колеса 8 по дорожному полотну 6, БИУС передает сигнал по электропроводам 3 на исполнительный элемент с механической муфтой 7, связанный жестко с ходовой частью 9 машины 1. Исполнительный элемент с механической муфтой 7 предназначен для введения в зацепление с боковой контактной поверхностью ведущего колеса 8 вращательного устройства 5. При этом крутящий момент от ведущего колеса 8 передается на вращательное устройство 5, придавая ему вращательное движение. Вращаясь непосредственно около ведущего колеса 8 вращательное устройство 5, приводит в движение жестко скрепленные с ним металлические цепи 4. Под действием центробежных сил металлические цепи 4 попадают непосредственно под проскальзывающее по дорожному полотну 6 ведущее колесо 8, обеспечивая повышение сцепных свойств ведущего колеса 8 с дорожным полотном 6. В период отсутствия зацепления вращательного устройства 5 с ведущим колесом 8, металлические цепи 4 работают как антистатик, снимая остаточное напряжение машины 1.Arrows

the direction of rotation of the metal chains is shown 4. To increase the coupling properties of a wheeled vehicle, the chassis 9 of machine 1 uses a device that includes an actuator with a mechanical coupling 7, controlled by electrical wires 3 of the BIUS 2. BIUS 2 when the machine 1 moves along slippery roadway 6 determines the loss of coupling properties of a particular drive wheel 8 (or all wheels) with the roadway 6 and controls the operation of the actuating element with a mechanical clutch 7. When slipping the drive wheel 8 on the roadway 6, the BIUS transmits a signal through electrical wires 3 to the actuator with a mechanical coupling 7, rigidly connected to the chassis 9 of the machine 1. The actuator with a mechanical coupling 7 is designed to engage rotational rotational gear 8 device 5. In this case, the torque from the drive wheel 8 is transmitted to the rotary device 5, giving it a rotational movement. Rotating directly near the driving wheel 8, the rotary device 5 drives the metal chains 4 rigidly attached to it. Under the action of centrifugal forces, the metal chains 4 fall directly under the driving wheel 8 sliding along the roadway 6, providing an increase in the coupling properties of the driving wheel 8 with the roadway 6. In the absence of engagement of the rotary device 5 with the drive wheel 8, the metal chains 4 work as an antistatic, removing the residual voltage of the machine 1.

An example of the method. When the machine 1 moves, the BIUS 2 determines the loss of the coupling properties of the drive wheel 8 with the roadway 6. The signal via electrical wires 3 from the BIUS 2 is transmitted to the actuator with a mechanical coupling 7, rigidly connected to the chassis 9 of the machine 1. The actuator with a mechanical coupling 7 introduces in rotation with the lateral contact surface of the drive wheel 8, the rotary device 5. The torque from the drive wheel 8 is transmitted to the rotary device 5, rotating it. The rotation of the rotary device 5 drives the metal chains 4, which fall between the drive wheel 8 and the roadway 6, providing increased coupling properties.

The proposed method allows to automate the process of increasing the coupling properties of a wheeled vehicle with a roadbed, the occurrence of a skid of a car, and reduce emergency situations on the road.
