WG2229020003 Внутренняя пружина толкающего блока

This inner spring for push block is a core component of the synchronizer shifting mechanism in Sinotruk gearboxes. It is precisely wound from high-purity alloy spring steel wire and professionally heat-treated by quenching and tempering, delivering balanced elasticity and rapid reset performance.
With uniform coil pitch and precise concentricity, it is manufactured strictly in accordance with original factory dimensions and craftsmanship, perfectly matching the push block and outer spring.
It mainly undertakes gear positioning buffering and reset functions, cushions shifting impact force and prevents gear looseness and jumping.
It can withstand long-term exposure to high temperature, oil contamination inside the gearbox and vehicle bumping vibration, and is not prone to relaxation, deformation or fracture failure. Adopting original universal specifications, it supports direct replacement and installation, suitable for all types of heavy-duty truck gearbox working conditions.
Selected high-elasticity and wear-resistant spring steel material, it features strong toughness and outstanding fatigue resistance, with elastic force free from attenuation under long-term high-frequency stretching and contraction.
Adopting precision winding technology, it has a regular structure with uniform stress and accurate positioning without deviation, effectively ensuring reliable gear clamping and clear gear engagement.
It resists high and low temperatures as well as gearbox oil corrosion, and is not prone to aging and failure under harsh working conditions.
Strictly complying with original factory dimensional standards, it enjoys excellent interchangeability and can be directly installed for replacement without grinding or modification.
It steadily optimizes shifting feel, prevents gear slipping and gear jumping faults, extends the service life of synchronizers, and reduces vehicle maintenance frequency and operational maintenance costs.
