The internationally accepted illumination aging test method is the xenon lamp aging test. The xenon lamp aging test chamber can simulate the full sunlight spectrum of sunlight, the Xenon lamp weathering test chamber simulation and the enhanced weathering accelerated aging test, especially suitable for various kinds of tests. Simulated daylight illumination artificial aging test for plastics, paints, coatings, automotive interior parts, geotextiles, textiles, dyes, leather, electrical and electronic products, color building materials, wire and cable, etc. The xenon lamp spectral wavelength of the xenon lamp aging test chamber is substantially consistent with the spectrum of sunlight in the range of 295 nm to 800 nm. Through the filtering of glass filters, it can effectively simulate ultraviolet, visible and infrared. The xenon lamp aging test chamber is used to test many products. These products are sensitive to long-wavelength, visible light and infrared rays of ultraviolet light, thus achieving the goal of detecting products.
Tractor, Head Tow Truck, Front drive capability called the front tractor, rear no traction drive capability of the car called the trailer, tractor trailer is pulled along. Tractor and trailer is connected in two ways: The first is the front half of the trailer after the tractor ride in the section above the saddle traction, tractor trailer behind the bridge to withstand the weight of the part, which is the tractor; second species is the front end of the trailer attached to the rear end of the tractor, the tractor only pull forward, dragging the trailer to go, but do not bear the weight of the trailer down, which is all linked.
Tractor, Head Tow Truck principle
Tractor, Head Tow Truck Traction Control System Traction Control System, referred to as TCS, also known as ASR or TRC. Its role is to make the car under various traveling conditions can get the best traction. Traction control system control device is a computer, the computer detects the use of four wheel speed and steering angle of the steering wheel when the car is accelerating, if it detects that the drive wheel and non-driving wheel speed difference is too large, the computer immediately determine the driving force is too large issuing a command signal to reduce the amount of oil the engine, reducing the driving force, thereby reducing the driving wheel slip rate. Computer control through the steering wheel steering angle sensor driver intent, then use the left and right wheel speed sensor detects the left and right wheel speed difference; in order to determine whether the degree of steering the car and the driver's steering intention of the same. If the car detects understeer (or oversteer), the computer immediately determine the driving force of the drive wheel is too large, it issued a directive to reduce the driving force, in order to achieve the driver's steering intention.
Tractor, Head Tow Truck Traction control system to prevent the vehicle driving on snow and other slippery surfaces the driving wheel idling, the vehicle can smoothly start and accelerate. Especially in snow or muddy road, traction control system can ensure the smooth acceleration, to prevent the vehicle wheel slip occurs due to sliding or drift.
