Abstract

The invention relates to car with adjustable wheelbase, of which the distance of fore-and-aft wheel can be adjusted by driver proactively. The invention is especially adept to four-wheel electric automobile. The mobile comprises car body, power system, running system and control system. Said running system, which possesses regulating mechanism of wheel base to adjust distance of fore-and-aft wheels, comprises front dowel steel, rear dowel steel, wheel base of regulating lead screw, sliding nut, motor of wheel base regulating and sliding beam. Motor of wheelbase regulating drives connects with wheelbase of regulating lead screw via gear engagement. The front of sliding beam connects with adjustable shelf, the top connects with car frame via damping spring and the under-part set a supporting beard, in which supporting roll covered in back beam is inbuilt. The invention can enhance initial starting accelerating, climbing, cross-country and balancing performance and has the properties of rationalized carrying and actuating approach, high brake performance and high reliability.

Description

technical field [0001] The invention relates to an automobile with an adjustable wheelbase, which belongs to the technical field of automobiles, and is an automobile whose distance between front and rear wheels can be actively adjusted by a driver, and is especially suitable for various types of four-wheel electric automobiles. Background technique [0002] The current automobile research is devoted to the improvement of the performance of automobile acceleration, stability and off-road. However, the power of the engine cannot be fully exerted due to the restriction of the ground adhesion coefficient when the existing fixed-wheelbase vehicle accelerates from the start, thereby affecting the acceleration performance at the low speed stage of the start. In addition, if a vehicle with a fixed wheelbase is improved into a vehicle with an adjustable wheelbase, its off-road performance, climbing performance and stability performance will also be improved. In the prior art, there ...
