Problems solved by technology
Apparently, when a car turns from facing north to facing south, the solution of self-rotation only needs a space whose diameter is about the length of the car; and the method of revolution will require a large space for turning. For commercially available cars, the turning diameter usually exceeds twice the length of the car. For example, a car with a length of 4.8 meters has a minimum turning diameter of 10 meters, which makes it very inconvenient to turn around.
[0006] Apparently, existing commercially available cars do not have the function of self-rotation

Embodiment 2
[0121] The telescopic wheel assembly and arrangement of the front and rear transverse wheels in the second embodiment are the same as those in the first embodiment, and the description will not be repeated here.
[0122] Picture 20 It is a schematic diagram of the analysis of the movement of each wheel when the car makes a tail-flick movement in the second embodiment of the present invention. The graph is analyzed with the bottom view of the vehicle bottom. In the picture, the front, middle and rear telescopic mechanisms are fully extended downwards, four longitudinal wheels are lifted off the ground, two horizontal wheels and two universal wheels support the whole car, and the center point of the front horizontal wheel 1 wheel is O Point, MN is the common wheel axis of the front and rear transverse wheels. Obviously, point O falls on the straight line MN. The current transverse wheel 1 is in the braking state, and when the rear transverse wheel 1 is driven by its hub motor to ...

Disclosed is an eight-function car. The car is provided with a telescopic-wheel assembly (4). When all telescopic devices fully extend in position, the wheel axes of each transverse wheel (1) lie in a same plane S, and the plane S is parallel to or coincident with the longitudinal symmetry plane of the car. A ground vertical line with the touchdown-point of each universal wheel (2) as a pedal is parallel to the plane S. The longitudinal wheel-train achieves the longitudinal-running function and the turning function according to the prior art; driven by a power system, the transverse wheel-train achieves the established motion under the control of a control system, so as to achieve six functions of swinging-head, oversteering, self-rotation, transverse-moving, self-rescue, and lifting with one end. The telescopic-wheel assembly (4) comprises telescopic devices and wheels provided at the lower end of the telescopic devices. The telescopic device consists of multi-link mechanism formed by connecting multiple connecting rods, a linear motor (405) and a wheel carrier plate (409). The car has the longitudinal-running function and the turning function of the commercially available general car, and has the six functions of swinging-head, oversteering, self-rotation, transverse-moving, self-rescue, and lifting with one end.
Description
Technical field [0001] This patent belongs to the field of land-use trolley vehicles. Background technique [0002] The existing commercially available ordinary cars have only two functions, that is, longitudinal driving and turning. These two functions are the existing technology, this manual will not elaborate, this manual will detail the six new functions added to the car. The wheels of existing commercial cars roll along the longitudinal direction of the car without deflection, so they are called longitudinal wheels. Opposite the longitudinal wheels are the transverse wheels. In this patent, wheels that can only roll in the transverse direction of the car (direction perpendicular to the longitudinal direction of the car) are called transverse wheels. It can be seen that the existing commercial vehicles do not have a lateral driving function. [0003] Longitudinal driving is the most important function of a car. In order to solve this technical problem, technicians in the au...
