Abstract

FIELD: transportation.

SUBSTANCE: device for increasing adhesion of car wheels with icy road is characterized by the fact that the driver has the possibility of using a control member to control the lifting mechanism connected to it by means of electric wires, which is mechanically connected to the electric motor. When the control element is actuated, the signal is transmitted to a lifting mechanism lowering and lifting the electric motor, as well as to the electric motor itself, thereby driving its shaft into rotary motion. On the shaft there rigidly fixed are metal chains unwound at rotation of the shaft in the direction directly between the driving wheel and the roadbed, which allows to increase the wheel engagement with the roadway.

EFFECT: increase in coupling properties of car wheels with a road cloth, improvement of indicators of mobility of a wheeled vehicle, exclusion of deterioration of a road cloth.

Description

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

There is a method of increasing the adhesion of the wheels of a car to an icy road, for example, used in a tread of a pneumatic tire containing annular ribs consisting of checkers in which slit-like slots are made. The depth of the slit each surface consists of two sections. The first is made wavy, and the second is made flat. On the flat areas of the opposite surfaces of the sipe, one row of lateral protrusions and reciprocal recesses, arranged with a gap between them, is made (see. Patent for invention №2589531. Priority date 28.11.2014. Published: 07/10/2016. Bulletin №19. Authors: Grigorenko A.V., Andreev M.Yu., Zhogin V.A. KORDIANT Open Joint-Stock Company. Open Edition).

A known method of coupling the wheels of a car to an icy road allows, through the construction of a pneumatic tire, namely its tread, to improve the removal of moisture from the contact patch. However, this method has the disadvantage that when driving the wheels on the icy road section, the grip properties of the tire bearing surface with the roadway are significantly reduced, as a result of which a skid may occur, leading to an emergency on the road.

In addition, there is a method of coupling the wheels of a car to an icy road in the form of an anti-slip device containing levers fixed to the bearing hub, the free ends of which are made with lugs and curved to cover the tire tread of the tire, and a device for pressing the levers to the tread in the form of a push hub installed coaxially with the bearing hub and connected with it by means of a clamping bolt, and the pressure hub is made with a pressure ring with guide elements through which the levers with the the possibility of radial displacement, (see. Patent for invention №2023598. Published: 11/30/1994. Author Korotenko EB Open edition). This method is selected as a prototype.

The known method allows to increase grip when driving on icy and snowy roads in winter. However, when driving within the boundaries of a large city, as a rule, in the winter season, road services sometimes use chemical reagents. In such places, there is no ice cover on the road, and the use of this device should be short-term, as it can deteriorate the grip properties of the wheels, the mobility of the vehicle as a whole, and also lead to damage to the road surface.

The present invention is to improve the adhesion properties of the wheels of a car with ice roadway, improving the mobility of the vehicle, with the exception of damage to the roadway.

The technical result of the proposed invention is to improve the adhesion properties of the wheels of the car with the roadway, improving the mobility of a wheeled vehicle, with the exception of damage to the roadway.

The technical solution of the proposed invention is to supply the running gear of a wheeled vehicle with a device comprising a control body connecting a lifting mechanism and an electric motor, on the shaft of which metal chains are located directly beside the tires of the driving wheels.

At the same time, the method of increasing the wheel adhesion of a car with an icy road is based on the fact that when a car moves on ice and tires slip over the ice, the driver, acting on the control, transmits a signal through the electrical wires to a lifting mechanism that raises and lowers the electric motor. metal chains are attached. When the shaft of an electric motor rotates, the metal chains under the action of centrifugal forces unwind to the sides, falling between the contact surface of the wheel and the roadway, thereby enhancing the grip properties.

The method of increasing the grip of the wheels of a car with an icy road, characterized by the fact that with the help of the control body, a signal is transmitted through the electric wires to a lifting mechanism which lowers and lifts the electric motor and puts it into operation, uses the torque of the electric motor shaft, unwinds the metal chains located on the shaft in the direction between the drive wheel and the roadway, increasing the grip of the wheel with the roadway.

The invention is illustrated in FIG. 1, which shows a method for increasing the adhesion of the wheels of a car to an icy road, where: 1 is a car; 2 - governing body; 3 - electric wires; 4 - metal chains; 5 - electric motor; 6 - roadbed; 7 - lifting mechanism; 8 - drive wheel; 9 - chassis.

показано направление вращения металлических цепей 4. Для повышения сцепных свойств колес автомобиля, в составе ходовой части 9 машины 1 используется устройство, имеющее в своем составе подъемный механизм 7, управляемый по электропроводам 3 органом управления 2. При проскальзывании ведущих колес 8 по скользкому дорожному полотну 6 при движении машины 1, водитель через орган управления 2 управляет работой подъемного механизма 7. Передача сигнала по электропроводам 3 на подъемный механизм 7, связанный жестко с ходовой частью 9 машины 1 приводит его в работу, а именно он поднимает и опускает жестко с ним связанный электромотор 5, который также посредством электропроводов 3 связан с органом управления 2. При этом крутящий момент от вала электромотора 5 передается на жестко связанные с валом металлические цепи 4. Вращаясь непосредственно около ведущего колеса 8, металлические цепи 4 под действием центробежных сил попадают непосредственно под проскальзывающее по дорожному полотну 6 ведущее колесо 8, обеспечивая повышение сцепных свойств ведущего колеса 8 с дорожным полотном 6. В нерабочем (не включенном) состоянии электромотора 5 и поднятом состоянии подъемного механизма 7, металлические цепи 4 работают как антистатик, снимая остаточное напряжение с машины 1.Arrows

shows the direction of rotation of the metal chains 4. To improve the adhesion properties of the wheels of the car, the chassis 9 of the machine 1 uses a device that includes a lifting mechanism 7 controlled by the electric wires 3 by the control body 2. When the driving wheels 8 slip through the slippery road surface 6 when the vehicle is moving 1, the driver, through the control body 2, controls the operation of the lifting mechanism 7. Signal transmission through the electric wires 3 to the lifting mechanism 7, which is rigidly connected with the chassis 9 of the machine 1, leads it o to work, namely, it raises and lowers the electromotor 5 rigidly connected with it, which also by means of electric wires 3 is connected with the governing body 2. At this, the torque from the shaft 4 of the electric motor 5 which is rigidly connected with the shaft wheels 8, metal chains 4 under the action of centrifugal forces fall directly under the drive wheel 8, which slips along the roadway 6, providing an increase in the grip properties of the drive wheel 8 with the roadbed 6. Outside (not included) the state of the electric motor 5 and the raised state of the lifting mechanism 7, the metal chains 4 work as an antistatic, removing the residual voltage from the machine 1.

An example of the method. When the machine 1 moves, the driver, through the control body 2, transmits a signal through the electric wires 3 to the lifting mechanism 7, which is rigidly connected to the chassis 9 of the machine 1 and the electric motor 5, as well as the electric motor 5. When the electric motor 5 is operating, the torque from the electric motor 8 shaft rotates the metal chains 4, which fall between the driving wheel 8 and the roadway 6, providing improved grip.

The proposed method allows you to automate the process of improving the adhesion properties of the wheels of the car with the roadway, the occurrence of skidding machines, to reduce accidents on the road.
