Shunting type rear-end collision prevention and side impact protection device for truck

Abstract

The invention discloses a shunting type rear-end collision prevention and side impact protection device for a truck, which can completely avoid severe consequences of top chopping caused by rear-end collision or side impact, and is composed of a cross beam extension fixing support, multiple collision shunting unit modules and a fixing support at the rear parts of the modules. When the rear-end collision happens, the headstock of a rear car firstly crashes into pulleys in the lowest rows of the collision shunting unit modules, and the impact force is shunted under rotation of three sets of pulleys, so that the headstock of the rear car stops on the carriage of the truck along the inclined surface, and the severe consequences that the rear car crushes into the bottom of the truck and is chopped at the top can be avoided; the shunting type rear-end collision prevention and side impact protection device works similarly when the side impact happens.

Description

Technical field [0001] The invention relates to a split-type truck anti-rear collision and side collision protection device, which is completely mechanically operated and does not need the assistance of electronic equipment. Background technique [0002] At present, the known anti-rear collision protection device for trucks is mainly composed of several interlaced steel rods installed on the rear and both sides of the truck chassis. During rear-end collision or side collision, the device collides with the front bumper of the rear car, thereby deforming and absorbing Collision energy plays a role, but at the same time there are many shortcomings: 1. The protection effect is not ideal. If the rear car is relatively low, the traditional truck anti-rear collision protection device is often broken due to too much kinetic energy, and it is directly inserted into the bottom of the car, forming Serious consequences of roof cutting; 2. If the traditional truck anti-rear collision pro...

Problems solved by technology

[0003] In order to overcome the unsatisfactory protection effect of the existing truck anti-rear-end collision protection device, the present invention provides a split-type truck anti-rear-end collision protection device. The installation does not change the vehicle's own circuit and mechanical structure, which can fully avoid the serious consequences of rear-end collision or side collision with the truck to cause the roof to be cut
