Rescue method for heavy-duty traction vehicle when heavy load breaks down

Abstract

The invention relates to a rescuing method for a heavy type towing vehicle overloading failure. The end, connected with the rear axle control air pressure output end of the main brake valve, of a first air pipe between a failure vehicle towing vehicle head main brake valve and a trailer brake control valve is dismantled and connected to a trailer brake connector behind the trailer brake control valve on a rescuing towing vehicle head through a connection air pipe; the end, connected with the compressed air output end of a dryer, of a second air pipe between a failure vehicle towing vehicle head four-loop protective valve and the dryer is dismantled and connected to trailer inflation connector of the rescuing towing vehicle head through a connection air pipe; if an engine of a failure vehicle towing vehicle head cannot run normally, a steering wheel high-pressure oil pipe connector and a steering wheel oil return pipe connector of the failure vehicle towing vehicle head are connected with a rescuing towing vehicle head steering wheel through a high-pressure oil pipe and a tee pipe coupling respectively. By the adoption of the rescuing method, a failure vehicle can achieve synchronous brake with the rescuing towing vehicle head in the towing process, and the failure vehicle towing vehicle head can achieve the steering function on the condition that the engine breaks down.

Description

technical field [0001] The invention relates to the technical field of vehicle rescue, in particular to a rescue method for a heavy-duty tractor vehicle when its load fails. Background technique [0002] With the rapid development of my country's automobile industry, heavy-duty traction vehicles have played an irreplaceable role in my country's economic construction. However, during the use of heavy-duty tractor vehicles, the situation that the vehicle cannot operate normally due to vehicle failure or other objective reasons occurs from time to time. Although the heavy-duty tractor can replace the tractor head, it is necessary to send out the rescue tractor head of the tow trailer and the tractor tow the faulty tractor head respectively during rescue, and the rescue cost is too high. Therefore, the rescue of the heavy-duty tractor that breaks down mainly adopts the method of integral traction at present. [0003] When towing as a whole, the rescue vehicle pulls the rescued...

Problems solved by technology

This inertial forward force will not only have a destructive effect on the hard traction device, but in severe cases, the rescue vehicle will also produce inertial forward force and cause sideslip, which has caused great hidden dangers to driving safety.
