A kind of remote-controlled toy vehicle
Technical field
The utility model relates to a kind of remote-controlled toy vehicle.
Background technology
Existing true car, especially some racing cars when swerving, in order to pass through bend faster, are usually adopted the drift technology, make car that suitable sideslip be taken place, and promptly pass through bend.The principle of drift is: make the trailing wheel of car lose major part (perhaps whole) earth-grasping force, front vehicle wheel is wanted to keep earth-grasping force (can only lose fraction at most simultaneously, preferably can obtain extra earth-grasping force), at this moment as long as front vehicle wheel has certain cross force, car so just can produce sideslip with regard to whipping, and the circuit that breaks away is controlled accurately by the driver, be used for promptly by bend drift that Here it is.If the sideslip of car is out of control, then can not be called drift.In order to allow the driver can control the sideslip circuit of car accurately, it is curved to drift about accurately, and therefore the structure to car has special requirement, such as: preferably adopt rear wheel drive etc.And some professional driver reaches the curved purpose of drifting about accurately in order accurately to control the sideslip of car, need reequip accordingly car toward contact.
And existing remote-controlled toy vehicle, there are huge difference in its structure and true car, test discovery through the applicant, and existing remote-controlled toy vehicle all can't accurately be controlled the sideslip of car as true car, and it is curved to drift about accurately.Through applicant's discovery that studies for a long period of time, the problem that existing remote-controlled toy vehicle can't drift about goes out on the structural design of remote-controlled toy vehicle itself, and the structural design of existing remote-controlled toy vehicle can't satisfy the needs of drift.
The tire that existing remote-controlled toy vehicle adopted all is soft tire, and is carved with anti-skidding decorative pattern on the tire circumference face, and the tire and the frictional force between the ground of remote-controlled toy vehicle are bigger, and this has just caused remote-controlled toy vehicle to be difficult to the phenomenon that occurs skidding.
