Anti-deflection vehicle-mounted anti-collision buffering cushion
The utility model discloses an anti-deflection vehicle-mounted anti-collision buffering cushion which comprises a base connected with a vehicle body, an energy absorption box fixed to the side, away from the vehicle body, of the base and a top plate arranged on the side, away from the base, of the energy absorption box. Sliding bases are horizontally and fixedly connected to the two sides of the top and the bottom of the face, opposite to the base, of the anti-collision steel plate, shear forks are horizontally arranged at the positions, close to the top and the bottom of the inner wall, of the interior of the energy absorption box, and the eight ends of the shear forks are slidably connected with the sliding bases at the corresponding positions correspondingly. The shear forks and the multi-section spring telescopic rods play a role in guiding the anti-collision steel plate and the energy absorption box to be sunken due to collision, and no matter which side of the rear portion of the energy absorption box is collided, the two sides of the anti-collision steel plate can be sunken and contracted at the same time under the action of the shear forks and the multi-section spring telescopic rods. Secondary collision caused by different recesses due to uneven stress on the two sides during steering of the vehicle is prevented, and the safety of the collided vehicle is improved.

A traction trolley system for heavy vehicle collision test
ActiveCN118980486BIncrease clamping frictionImprove reliabilityVehicle testingShock testingMechanical engineeringElectrical and Electronics engineering
The present invention discloses a traction trolley system for heavy-duty vehicle collision test, including a test track, a traction trolley, an unlocking block and a traction rod. The traction trolley can be slidably installed on the test track. The traction trolley includes a trolley body and a clamping assembly. The unlocking block is fixedly installed on the test track. When the traction trolley passes through the unlocking block, the clamping assembly collides with the unlocking block to unlock, and the traction trolley is separated from the traction rope. The traction rod is unidirectionally detachably connected to the traction trolley, and the vehicle to be tested is towed and connected to the traction trolley through the traction rod. A stop device is provided on the test track, and the stop device is located in front of the unlocking block. Beneficial effects: The present invention adopts a clamping hole structure with straight hole portions at both ends and a serpentine portion in the middle. The inner wall of the clamping hole is provided with grooves to provide sufficient traction clamping force for heavy vehicles: the quadruple energy absorption protection measures ensure that after the test is completed, the traction trolley can be safely and controllably decelerated and finally stopped to prevent accidents or secondary collisions.
