The system includes a polous placed on a board fastened to the circular base, an arched piece connected one shaft in each of the two hydraulic jacks attached to the board, a plurality of bushings fastened to a wheel ring attached to the polous, a rotating helm attached to one end of a bushing shaft attached to each of the bushings, a guide bar attached to the bushings and bushings shaft and a spring arranged over the guide bar. The movement of the vehicle wheel causes the rotating helm to come in to contact with the arched piece which in turn stroke the bushing shaft resulting in a reciprocal movement inside the bushings thereby providing traction between the vehicle wheel and a land surface. ## Claims ### Claim 1 A system for reducing friction in vehicles, the system comprising: a circular base; a board fastened to the circular base; an axle rod placed on the board; at least two hydraulic jacks fastened to the board; at least one shaft attached to each of the at least two hydraulic jacks; an arched piece connected to the at least one shaft; a wheel ring attached to the axle rod; a plurality of bushings fastened to the wheel ring; a bushing shaft attached to each of the plurality of bushings; a rotating helm attached to one end of the bushing shaft; a guide bar attached to the bushings and the bushings shaft; and a spring arranged over the guide bar between the bushings and the bushing shaft; wherein a movement of a vehicle wheel causes the rotating helm to come into contact with the arched piece which in turn actuates the bushing shaft resulting in a reciprocal movement inside the plurality of bushings thereby providing a traction system between the vehicle wheel and a land surface to generate a maximum friction in a required time and to control a quantity and scale of friction thereby dynamically varying a friction according to a user requirement and wherein the friction is controlled by varying the hydraulic jacks manually through a hydraulic pump. ### Claim 2 (depends on 1) The system according to claim 1, wherein the traction system is installed on an internal side of the vehicle wheel. ### Claim 3 (depends on 1) The system according to claim 1, further comprises a plurality of reinforcement pipes for the at least two hydraulic jacks. ### Claim 4 (depends on 1) The system according to claim 1, further comprising an outer shell enclosing the axle rod and wherein the outer shell forms a fixed section and wherein the axle rod forms a dynamic section of the vehicle wheel. ### Claim 5 (depends on 1) The system according to claim 1, wherein the circular base, the board, the at least two hydraulic jacks, the reinforcement pipe of the at least two hydraulic jacks and the arched piece are arranged on the fixed section of the vehicle wheel. ### Claim 6 (depends on 1) The system according to claim 1, wherein the wheel ring, the bushings, the bushing shaft, the rotating helm, the guide bar and the spring are arranged on the dynamic section of the vehicle wheel. ### Claim 7 (depends on 1) The system according to claim 1, wherein the bushing shaft is arranged vertical or inclined to the land surface. ### Claim 8 (depends on 1) The system according to claim 1, wherein the circular base is connected to a shaft of one hydraulic jack in the at least two hydraulic jacks and the wheel ring. ### Claim 9 (depends on 1) The system according to claim 1, wherein a number of bushing shafts, to which the rotating helm is attached through the guide bar arranged with the spring, is within 4 to 12. ### Claim 10 (depends on 1) The system according to claim 1, wherein the circular base includes a radius which is less than a radius of the vehicle wheel. ### Claim 11 (depends on 1) The system according to claim 1, wherein the board is a base plate for the axle rod and the at least two hydraulic jacks. ### Claim 12 (depends on 1) The system according to claim 1, further comprises at least one hydraulic pump is connected to a vehicle engine to provide power to the at least two hydraulic jacks. ### Claim 13 (depends on 11) The system according to claim 11, wherein the at least one hydraulic pump is controlled by at least one of a vehicle operator or an intelligent system and wherein the vehicle operator manually decides a traction by adjusting a length of the shaft of the hydraulic jacks through the hydraulic pump. ### Claim 14 (depends on 13) The system according to claim 13, wherein the plurality of reinforcement pipes is connected to a control valve and the hydraulic pump. ### Claim 15 (depends on 1) The system according to claim 1, wherein the spring on the guide bar gets uncompressed when the vehicle wheel rotates and the rotating helm crosses the arched piece thereby pulling back the bushing shaft to an original position.
