Tension System

A special tension system is established to allow the timing belt or the timing chain to remain a suitable tension degree. That is to say, the device will not be not too loose to skip teeth or too tight to be damaged. It consists of a tensioner wheel or tensioner and a chain tensioner guide plate (chain guide). In the valve mechanism driven with synchronous belt, the tensioner wheel is in direct contact with the timing belt; the tension degree of timing belt can be changed by the adjustment of tensioner wheel position. In the valve mechanism driven with chain, the tensioner supplies pressure to the chain by the change of chain tensioner guide plate position so that the chain keeps an appropriate tension degree. The chain tensioner guide plate is in direct contact with the timing chain and plays a guiding role.

Tensioner

Tensioner and tensioner wheel serve as tension devices for the transmission system of valve mechanism in an engine. They act upon the timing chain or the timing belt of engine for guidance and tension so that both pats are always in optimum tension state during operation. The tensioner is a vulnerable part in automobiles. The timing belt in engines is easy to be elongated after long service time. The tensioner can automatically adjust the tension degree of timing belt so as to keep the belt from slipping and resulting in engine failure. Additionally, the tensioner allows the timing belt to run more smoothly and reduce the engine noise. If the tensioner fails, the engine will generate abnormal sound. This fault will even cause vehicle jitter and flameout, thus compromising the normal operation of automobiles. For replacement, it is best to replace both the timing belt and the timing chain so as not to avoid any hidden hazards. The tensioner wheel is generally divided into hydraulic and mechanical ways, and mainly composed of fixed enclosure, tension arm, wheel body, torsional spring, rolling bearing, spring sleeve, etc. It can adjust the tension automatically according to the tightness of the timing belt or the timing chain so that the transmission system operates in a stable, safe and reliable manner.

Product Strengths

1. Strong research and development team; the product is researched and developed reversely according to the specifications of original equipment so as to ensure the original torque and mounting size. The independently researched and developed testing equipment can simulate the real road conditions for engines in various harsh environments, such as high temperature, strong dust and quick speed; in this way, the product quality can be ensured through various tests.

2. Advanced production and manufacturing equipment; key parts undergo all performance tests; the material and the heat treatment process for tappet are strictly controlled to ensure its hardness and high wear resistance.

3. The aluminum ingot made of new material ADC12 according to national standards is adopted for aluminum enclosure; the large-scale die-casting equipment is adopted for its die-casting process, the same process as the parts in original equipment; those efforts ensure the batch quality and cleanliness of work-blank and avoid both uneven density and porosity in products.

4. A new wear-resistant material synthesized by PA66+GF is adopted for guide rail; formulas are customized according to different products to ensure the stable molecular structure in the product. Precise injection molds ensure the profile and size of product completely conform to the design requirements.
