The ad hoc organization which uses to change or recover it to drive a direction on the car is called a car to change direction to fasten.The car changes direction to fasten to include to change direction to manipulate organization and change direction a machine and change direction to spread to move organization.
The car changes direction system and can press the energy dissimilarity for change direction to is divided into a machine to change direction system and motive to change direction system 2 types.Machine's changing direction system is to depend on a pilot to manipulate to change direction change direction of dish dint to carry out car wheel to change direction;The motive changes direction system then under the pilot's control and ask for help from liquid pressure or electric motor driving force that the car launches a machine creation to carry out car wheel to change direction.So the motive changes direction system to also be called to change direction motive to enlarge device.
Along with the quick development of car industry, the structure which changes direction device also has to very greatly change.The car changes direction the structure of machine a lot of, from use currently of widespread degree to see, mainly change direction a machine type to have 4 kinds:There is Gua pole sell type(WP type), Gua pole rolling a type(WR type), circulating ball type(BS type), Chi wheel gear type(RP type).These 4 kinds change direction machine pattern, already drive extensively of the usage is on the overwhelming majority car.
Among them, wheel gear Chi the type change direction a spread of machine to move the pair as the wheel gear and the Chi, its structure is simple and hasn't high request to the craft and the equipments and be easy to with horizontal pull pole consociation to arrange in the car structure but get to develop very quickly.Especially the liquid press type's motive change direction already extensively applied on the car.
The thesis theoretically elaborated the car changes direction the total design for fasten, its main structure analysis and design of zero partses compute etc., and still discussed a car to change direction to fasten of past, present condition and future.Then this text changes direction a publish of machine from the car with to car industry of development and start to talk about to the mankind's social influence, systematically introduced a car to change direction to fasten of design theories and design a technical development, change direction contents, characteristics and its development trend and some last words of machine design, design of objective regulation, beginning start decision and design process, and some developmentses get up in recent years of new technique, for example the four-wheeler of modern car change direction etc..
The thesis elaborated on wheel gear Chi the structure which change direction a machine and wheel gear Chi's parameter design, liquid which change direction a machine press dynamical work principle and liquid to press motive to change direction the machine function calculating research.
After the wheel gear Chi type liquid press detailed design and theories that the motive changes direction a machine to prove, the thesis still introduced relevant change direction to fasten of experiment.In addition to making use of the whole work function, credibility and life span that the driveway road experiments to investigate to change direction to fasten, Be also carry on changing direction the set which experiments to press to change direction to add dint device and motive to change direction a machine to always become with liquid of the set that the machine always becomes to experiment
