Loading machine anti-bumping and vibrating shock mitigation system

Abstract

The invention discloses a loading machine anti-bumping and vibrating shock mitigation system. An air pump outlet is connected with combination valves inlets, an combination valves outlet E is connected with an A mouth of a cylinder body in the shock mitigation system via a first one-way valve, a B mouth of the cylinder body of the shock mitigation system is connected with an inlet of a first overflow valve, an outlet of the first overflow valve is connected with an inlet of an air cylinder via a third one-way valve, the other path of the combination valves outlet E is connected with a C mouth of the cylinder body in the shock mitigation system via a forth one-way valve, a D mouth of the cylinder body in the shock mitigation system is connected with an air inlet of the second overflow valve, the outlet of the second overflow valve is connected with the air inlet of the air cylinder via the second one-way valve, the outlet of the air cylinder is connected with an air inlet of a safety valve, a rear frame of the shock mitigation system is connected with the air cylinder, the air cylinder is connected with a balance weight via an air cylinder piston rod, and a spring and a guiding rod are arranged between the rear frame and the balance weight. The loading machine anti-bumping and vibrating shock mitigation system is simple in structure, high in reliability, few in failure and easy to eliminate failure, so that affordable cost is low.

Description

technical field [0001] The invention relates to a vibration damping system for a loader, in particular to a vibration damping system for preventing the periodic vibration of the loader from pitching forward and backward. Background technique [0002] When the loader is driving, due to the different weights carried by the front and rear drive axles, the tires will deform differently, resulting in different distances from the center axis of the front and rear tires to the ground. In order to increase traction, the loader adopts four-wheel drive. , The speed transmitted by the engine to the front and rear axles is the same, which causes the speed of the front and rear wheels to be different when the whole machine is running. Assuming that the whole machine is empty, the speed of the front wheels will be greater than that of the rear wheels. As a result, when the front axle tires are rolling, the rear axle tires will slide forward due to the traction of the front wheels at the s...

Problems solved by technology

However, the selection of materials for hydraulic accumulators and related hydraulic valve components is relatively strict, the requirements for processing accuracy are very high, and the requirements for manufacturing technology are relatively advanced. A slight processing error may lead to the failure of the whole machine, so foreign products are generally used. brand; the hydraulic damping system consists of many valve body components, and all of them are under high pressure, which has poor reliability and is also dangerous; when the hydraulic damping system fails, it is often difficult to judge the fault, and in During maintenance, it is often necessary to drain the hydraulic oil to release the high pressure of the hydraulic system in order to maintain

In the process of releasing, it will inevitably lead to the leakage of hydraulic oil, so it will cause pollution to the environment, the maintenance is difficult, and the service cycle is long. Therefore, the comprehensive use cost of the entire hydraulic vibration damping system is expensive
