Problems solved by technology

Its disadvantages are: the solution is to change the wheelbase by changing the length of the car frame and the carriage, so the amount of change is large, and the pressure transmission cylinder type force transmission device is used, so the response speed is slow and cannot meet the requirements of instant change of the wheelbase; in addition , the program involves a truck with a narrow scope of application

Abstract

The axle-base adjustable automobile is specially applicable to lorries, vans, buses, car, cross-country vehicle and racing car, etc. It includes automobile body, power system, running system and operation system, in which the described running system has a wheel-base regulating device for regulating distance between front wheel axle and rear wheel axle, and said regulating device includes the components of groove frame, supporting wheel, supporting column, nut seat, screw rod and others. The invention can raise the automobile performances of starting, accelerating, climbing, balancing and braking.

Description

technical field [0001] The invention relates to an automobile with an adjustable wheelbase, which is an automobile whose wheelbase can be actively adjusted by a driver, belongs to the technical field of automobiles, and is especially suitable for large and medium passenger cars, trucks, large cars, off-road vehicles and racing cars. Background technique [0002] The current automobile research is devoted to the improvement of the performance of automobile acceleration, stability and off-road. However, the current fixed-wheelbase vehicles (except four-wheel drive) are restricted by the ground adhesion coefficient when starting to accelerate, so that the power of the engine cannot be fully utilized, thereby affecting the acceleration performance in the low-speed stage of starting. In addition, there is room for further improvement in the off-road performance, climbing performance (except for four-wheel drive models) and stability performance of vehicles...
