Retractable car automatic cowcatcher

Abstract

The invention discloses a retractable car automatic cowcatcher comprising a barrier sensing system, an electronic control hydraulic execution system and a collision energy absorption system. The collision energy absorption system is arranged at the front ends of vehicle front wheels, the barrier sensing system is arranged at the front end of a vehicle, and the electronic control hydraulic execution system is connected with the barrier sensing system and the collision energy absorption system. Safety running of a car is guaranteed, after a barrier is removed, the retractable car automatic cowcatcher can be retracted into a chassis, the passing ability of the car under the normal situation is ensured, the structure has the sufficient connecting strength and certain elasticity, and the barrier removing ability and travelling safety of the retractable car automatic cowcatcher are improved.

Description

technical field [0001] The invention relates to the field of automobile auxiliary technology, in particular to a retractable automatic obstacle remover for automobiles. Background technique [0002] Cars and transport vehicles with small engines will inevitably encounter obstacles during driving. [0003] On the one hand, since most of the tires of these vehicles adopt an inflatable inner and outer tire structure, in actual use, it is often easy to cause the tire to be cut by sharp metal foreign objects such as iron nails, iron filings, steel filings, and rivets embedded on the ground. This phenomenon not only causes vehicle failure to stop, repair tires or even scrap them for replacement, affecting normal work and transportation, but also causes safety hazards and environmental protection problems such as vehicle tilting, material falling, and site pollution after flat tires and punctures are more serious. [0004] On the other hand, when the vehicle is driving on an expre...

AI Technical Summary

Problems solved by technology

The traditional obstacle remover mostly adopts an integrated structure. The front part of the obstacle remover is a panel, and the panel has a single structure welded by a corresponding bracket. The bracket and the car body are connected by bolts; at the same time, the existing obstacle remover is large Some of them are only suitable for ordinary carbon steel car body materials. Their structures are relatively complex and their sizes are large, which cannot meet the requirements of simplicity and lightness. Moreover, the structural strength of some obstacle removers cannot meet the specific requirements of removing obstacles during driving.
