Eight-function vehicle, method for realizing each function, and telescopic wheel assembly used for the vehicle

Abstract

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 trackless vehicles for land use. Background technique [0002] The function of existing commercially available common car has only two aspects, is exactly longitudinal running and turning. These two functions are existing technologies, and this manual will not describe them in detail. This manual will describe in detail the six functions newly added to the car. The wheels of existing commercially available automobiles all roll longitudinally along the automobile without deflection, so they are called longitudinal wheels. Opposite the longitudinal wheels are the transverse wheels. In this patent, the wheels that can only be rolled along the lateral direction of the vehicle (direction perpendicular to the longitudinal direction of the vehicle) are called lateral wheels. It can be seen that the existing commercially available automobiles do not have the lateral running function. [0003] Longitudinal driving is the ...

AI Technical Summary

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
