METHOD OF AND DEVICE TO PREVENT TRAUMATISM AND DEATH OF PEOPLE UNDER WHEELS OF VEHICLES

摘要

FIELD: transport engineering. ^ SUBSTANCE: invention relates to safety devices installed on vehicles to prevent damage to pedestrians. Proposed method to prevent traumatism and death people under wheels of vehicles comes to the following: cylindrical member is installed in form part of vehicle horizontally over entire width at level of radiator. Said member has elastic envelope with 1.5 - 2 atm pressure inside. In process of vehicle braking by application of brakes and release of clutch, man is gripped, fixed and lifted vertically by 10- 20 cm from road bed. In additional to above stated, device contains receiver connected receiver connected with pneumatic cylinders by pneumatic lines through electromagnetic valves with springs. Rods of pneumatic cylinders are mechanically coupled with clutch and brake pedals. Rod of other pneumatic cylinder with valve is rigidly coupled with front wall of elastic cylindrical member. Pneumatic line is provided with hole connected with pneumatic valve which acts onto contacts electrically connected through current source with electromagnetic valves. Outputs of electromagnetic valves are connected by pneumatic lines with four pneumatic cylinders. Rods of two pneumatic cylinder are rigidly connected with bases of right-hand and left-hand grips, respectively. Contacts are rigidly fastened of bases of right-hand and left-hand grips. Said contacts can interact with contacts electrically connected through current source with electromagnetic valves installed on pneumatic lines for shifting rods of pneumatic valves in vertical plane relative to grips. ^ EFFECT: improved safety of traffic, prevention of traumatism and death of people caused by vehicles. ^ 3 cl, 3 dwg
