Trailer with coasting protection

Abstract

The invention discloses a semi-trailer truck with an inertia forward impact protection function. The semi-trailer truck comprises a tractor unit and a semi-trailer, wherein a braking sensing device isarranged in a cab of the tractor unit; the braking sensing device comprises a pedal and a sensor arranged on one side of the pedal; the semi-trailer is provided with an isolation and blocking device,an automatic locking device and a braking assisting device; the isolation and blocking device comprises an isolation and blocking net, fixing frames, a drum and drum driving motors; the fixing framesare arranged side by side on the left and right sides of the semi-trailer; the fixing frames comprise horizontal rods and a plurality of vertical rods; the front end of the isolation and blocking netis locked at the upper ends of the rear sides of intersections of the corresponding horizontal rods and the corresponding vertical rods through a telescopic rod; the lower end of the isolation and blocking net runs through the semi-trailer to be connected to the drum; output shafts of the driving motors are connected to a drum shaft through belts and belt pulleys; and the positions of two ends ofthe drum shaft are limited by position-limiting mechanisms. The semi-trailer truck with the inertia forward impact protection function has the characteristics of freight isolation and blocking, automatic locking, and braking assisting of the semi-trailer truck.

Description

technical field [0001] The invention relates to a trailer with an inertial forward rush protection function. Background technique [0002] When a heavy-loaded trailer brakes in an emergency, the cargo on the trailer slides forward under the action of inertia, which is prone to hitting the cab and seriously endangering the personal safety of the driver. When the goods are bumped during transportation, there will be a corresponding misalignment between the goods, resulting in loosening of the binding, and increasing the sliding distance when subjected to inertia. In addition, when the trailer is braking, it will continue to slide for a certain distance due to inertia, which can easily lead to traffic accidents. Therefore, designing a trailer with an inertial forward impact protection function that can be used to block goods, automatically lock and trailer brakes has a broad market prospect. Contents of the invention [0003] Aiming at the deficiencies of the above-mentione...
