Hydraulic power transmission system for load of emergency rescue vehicle

Abstract

The invention discloses a hydraulic power transmission system for a load of an emergency rescue vehicle, which comprises an engine of a rescue vehicle body, a power takeoff, a hydraulic motor, a gear shifting valve block, a hydraulic oil tank, a pressure regulating valve and a plurality of hydraulic loads, an output main shaft of the engine is in transmission connection with the power takeoff, and the power takeoff is in transmission connection with the hydraulic motor. The hydraulic motor is communicated with the gear shifting valve block through an oil way, the hydraulic oil tank is communicated with the hydraulic motor and the gear shifting valve block through oil ways, the gear shifting valve block is provided with an upper hydraulic loop port and a lower hydraulic loop port, the pressure regulating valve is arranged on one side of the gear shifting valve block, and the hydraulic loads are each provided with a set of load hydraulic loop ports. The gear shifting valve block is communicated with a hydraulic load oil way through an oil conveying pipe; power of a vehicle body engine is directly taken, hydraulic oil is driven by a motor to form a loop to drive a load to work, the transmission efficiency is high, the load is light and convenient to carry, operation and use are more convenient, endurance time is long, long-time emergency rescue use can be achieved, power is large, and various emergency rescue requirements can be effectively met.

Description

technical field [0001] The invention belongs to the field of emergency rescue, and in particular relates to a load hydraulic power transmission system of an emergency rescue vehicle using hydraulic power. Background technique [0002] When encountering some dangerous situations, emergency rescue vehicles are required to arrive at the scene. The rescue vehicles will be equipped with a lot of emergency equipment. At present, most of these equipment loads are diesel-powered, and some are equipped with electric power supplies, which are directly input from the mains. However, it is not very convenient to use. Whether it is a diesel type or an electric type with its own power supply, there are major defects. It is very heavy and inconvenient to carry, and the operation is not convenient. Meet emergency needs. [0003] The technical problem to be solved by the present invention is to provide a load hydraulic power transmission system for emergency rescue vehicles that is light in...
