The Emergence Of Electric Winch Led Technology
Vehicle electric winch was born during World War I
, as the road conditions were very poor, in addition to other cities, suburbs full of stone and Wong Nai Road, an ordinary car because of poor rains the relationship between speed, it is easy to get stuck. At that time, some people use the electric winch from the ship pier are inspired to change it in the truck and drive it to the chain, this design is very successful, since cars began to be widely used with a electric winch. To increase the capacity of off-road self-help, the U.S. military in the 20th century, developed the first generation of 40 years with the electric winch jeep. It uses direct shaft drive PTO electric winch, due to take power in the engine directly, so super torque, toughness and durability are very good, but the disadvantage is that the car overturned, the engine not running will not be able to use, and its size, weight are very, very limited application of the model, costs are too high, so penetration is very low. 60 years of the 20th century, electric winch started. Its advantage is the light weight, low cost, self-loading Chaigai on a different car, and even if the engine can not operate electric winch can also operate.
Fracture of the electric winch cable and the car will cause harm. Because of space constraints, the design of the cable can not use the same ordinary mechanical overload factor. Safety is the first considered in the design, can do so, electric winch may even reach the nominal loads are; If the focus on working ability, then the safety of the user always have to be worried about, and once safety problems arise, work capacity will also irrelevant. To resolve this contradiction, T-MAX in the motor and the drum between the addition of a torque limiter. The two parts of the device were linked with the motor and drum, using the friction theory to give a certain overload electric winch; break when loads default friction limit, the torque limiter of two parts started sliding, that motor is still rotation, but less than a power transmission cable drum winding wheel, pull no more, no worries of broken cables. But this time should stop for the electric winch power, so as not to overheat damage torque limiter.
Relay
electric winch control the implementation of the one part, it will affect the efficiency of the overall effect of electric winch. Traditional electric winch has two relays were generally positive and negative current control. T-MAX will be integrated into a positive and negative relay to reduce the terminal assembly point, in the traditional silver-plated copper contacts on the films of cadmium, so that contact resistance is greatly reduced. In addition, the optimization of internal structure to make contact off more quickly and thoroughly, less arc on the contact damage, and thus a longer relay life. The relay cost much higher than ordinary products, it mainly assembled in the high-end models.
The optional electric winch
Winch for your vehicle purchase, of course, the power to choose a large, but if based solely on one to select, then winch it will be too heavy, thus affecting the car's driver and stability. To know which car best suits your winch, you must know that their cars in the country, and to understand the characteristics of each winch. Suggest that you may wish to refer to the following formula, choose the more well matched with the car winch: maximum load winch full weight 1.5. If the full weight of 6000 pounds (about 2,700 kg) car to count, it needs at least a 9,000-pound winch.
