25 t forklift steering cylinder improvement

2020-25 t forklift steering cylinder improvement 05 - 12 Xu Lisha ( Tianjin port a company) Total TCM25T forklift, 6 sets of 6 car use fixed number of year is longer, the steering cylinder are severe oil automatically forward phenomenon, repeatedly repair still can't completely solve, not only wastes the hydraulic oil, maintenance downtime caused by the oil leakage fault, also affect the working efficiency. According to TCM25T forklift steering cylinder structure and working principle of the following defects have been found: oil cylinder cylinder head and connecting parts are welded structure, easy cracking oil; Oil cylinder nail design is shorter, and bridge shell fit clearance is bigger, the turn not fixed. So the decision from the three aspects to solve the problem: 1, on both sides of the oil cylinder cylinder head and fixed bracket for the welding process, welding seam is more, and high positioning accuracy, prone to fracture at the spill. Change to the overall structure on the cylinder head, cylinder, to eliminate the weld leakage hidden trouble. 2, stable oil cylinder screw design is shorter, and a little thin, and the rear axle between positioning hole stabilization kuang quantity obviously, easy to make when using shifting cylinder force, cause the damage of oil cylinder. 3, the original piston seal design of coil type sealing ring, low service life, easy to leak, it changed to two polyurethane hole sealing ring seal, simple structure, good sealing effect. After modification can decrease The Times of equipment failure and improve the vehicle performance, save the maintenance cost and maintenance work intensity, ensure production use.
