DEVICE WITH ELECTRIC OR PNEUMATIC DRIVE OF COLLAPSIBLE MECHANISM TO STIMULATE REDUCTION OF VEHICLE SPEED Russian patent published in 2020 - IPC E01F9/529 G08G1/52 E01F13/04 

FIELD: machine building.

SUBSTANCE: invention relates to device with electric or pneumatic drive of collapsible mechanism to stimulate reduction of vehicle speed. Device includes rods (1.1, 1.2, 1.3) with accelerometers (1.4), configured to function as pressure sensors, transmitting information to controller (4), configured to immediately determine vehicle speed (20), and subsequent sending to drive with electric motor or pneumatic drive command to hoist collapsible mechanism (11) in case, if vehicle moves at speed exceeding speed programmed in controller. Folding mechanism (11) is arranged on base (10), which is installed on roadway (22) and on support structure (11.1) with shaft bearings, on which retainers are welded. Drives with electric motor or pneumatic drive are made with possibility of activation of lifting mechanism, which is made with possibility of lifting of lower collapsible rod (15), which is made with possibility during its lifting simultaneously to lift upper folding rod (16) to height determined by retainers (17.1 and 17.2). Front lateral edge of the lower collapsible rod (15) enters the groove located on the lower surface of upper rod (16), forming an angular positioning, which is made with the possibility to transfer the impact force of wheels to the upper rod at the specified angle to the lower rod.

EFFECT: providing maximum strength and stability of the device at impact of wheels from passing vehicles at a rate exceeding the speed programmed in the controller.
