The development of mankind is in an infinite process, and the development of the city is in a limited space. The three-dimensional urban architecture and urban traffic corresponding to the three-dimensional. In order to solve the problem of three-dimensional traffic in the city, the car elevator came from the dream to reality. Car elevator is a special elevator to solve the problem of vertical transportation of cars. Its standard load of 3000KG, 5000KG. Speed of 0.25-0.5m / s.

As an important vertical vehicle for vehicles, car lifts save up to 80% of the floor space and double the car's turnaround efficiency over traditional car ramps. Car lifts are called non-commercial vehicle lifts in the terms of GB7024-2008 "Elevators, escalators, moving walkways" and are defined as "elevators whose cabs are suitable for carrying small passenger cars" Device catalog is a kind of freight elevator. It is in the car 4S shop, repair shop, parking lot at the top of a large shopping mall, the supermarket has been more and more widely used.

Statistics show that by the end of 2010, car ownership in China has reached more than 8,000 vehicles, passenger cars amounted to more than 5000 million, in the foreseeable future, will remain about 20% growth rate. These vehicles, passenger cars are mostly concentrated in the cities, and with the urban expansion and the development of three-dimensional become congested, so the elevator car came into being and has been rapid development.
At present, there are mainly two types of car lifts widely used.
(1) hydraulic car elevator. It is safe and reliable, room settings and other advantages of low-rise buildings occupy a place. Among these, there are many cars designed specifically for the car, and some have the option to open the door photovoltaic system, more suitable for use in the car.
(2) Traction car elevator. In our city, the elevator car ownership is still the most traditional traction elevator car type, this type of freight elevator from Traction evolved, its mature technology and low cost advantages, occupy a certain market share .
In the context of the growing size of the modern city, car service for passenger cars also has a broad development prospects. In comparison, Traction elevator car from traditional freight elevators Traction technology evolved at this stage to meet the basic needs of three-dimensional development of the modern city, but in the long run, easy hydraulic elevator car layout and energy saving , More able to adapt to the future development trend of car lifts.

Adopting energy-saving and environment-friendly, stable operation, low noise, occupying a small area of permanent magnet synchronous traction machine: 1, the structure is simple, does not require gear box, the process is more simple, while reducing the size and weight, improve the effective space utilization . 2, low vibration noise, especially in low-speed operation area, the advantage is more obvious, stable operation, speed and high precision. The noise of the traditional geared elevator comes from the mechanical vibration generated by the gearbox and the vibration and noise of the motor rotating at high speed. Gearless traction machine without gearbox, the motor rated speed is very low, so the motor itself is very small vibration and noise, and thus greatly reduce the noise of the elevator system. 3, due to the realization of gearless speed, there is no second deceleration process, eliminating the gear box loss and improve efficiency. At the same time using permanent magnet excitation, no excitation current, no excitation loss, but also to improve efficiency. 4, high power factor. Power factor can be as high as 0.9 or more. 5, safe, reliable, comfortable and good. The use of permanent magnet synchronous motor drive, can effectively prevent the phenomenon of elevator slipped. At the same time, the motor can also provide enough torque at low frequency, low pressure and low speed to avoid the jitter of the elevator during the slow start-up process and improve the comfort of the elevator during the braking process. 6, can be arranged in a variety of traction machine roomless elevator, even in the organic room and small room layout also showed a higher degree of freedom and flexibility. Characteristics of car lifts
(1) Loaded and unloaded by cargo, the load of elevator plunges sharply, and the load of car is uneven. This is different from ordinary freight elevators loaded gradually load or gradually unloaded way is very different. Automobile elevator structural design should be able to adapt to this feature.
(2) The car has two control buttons box, the driver without leaving the car, you can manipulate the elevator;
(3) Rated load of 3 tons or more, large car area, enough to load a variety of small cars;
(4) Throughout the door set to facilitate the car out of the elevator.
(5) has a car suitable for carrying a car. Car is defined in the definition of car elevator car elevator to distinguish itself from other elevators the only element, which determines the car elevator car interior dimensions should be consistent with the shape of the passenger car. According to the new economic car definition of standards and "garage building design specifications", a variety of passenger car design models outline size and weight is determined (see Table 1). Therefore, car elevator car size should also be determined.
