Description
Technical Field
The invention relates to the technical field of vehicle manufacturing, in particular to an energy-saving vehicle frame with adjustable front wheel parameters.
Background
With the continuous high-speed development of society in recent years, the problems of energy conservation and environmental protection have been increasingly focused by people. The dramatic decrease in world oil reserves and the continual rise in crude oil prices have predicted that energy conservation is a necessary trend in current generation automobile development.
The traditional independent front suspension for the vehicle consists of an upper cantilever, a lower cantilever and a steering knuckle. The upper cantilever and the lower cantilever are connected with the vehicle body through bolts, and the steering knuckle is connected with the upper cantilever and the lower cantilever through a pair of fixed ball heads. The suspension has simple and firm structure, and is suitable for vehicles with fixed shapes and mass production. The disadvantage is that the positioning parameters of the steering wheel, including caster, left and right wheel base, are quite limited because the range of adjustment of the geometry of such suspensions is quite limited or unchangeable. Such suspensions generally cannot be adjusted over a wide range to compensate for errors caused by machining, assembly, etc., and the ability to change the running characteristics of the vehicle by adjusting these positioning parameters is extremely limited depending on the specific running conditions and conditions.
At present, most frames are mostly fixed structures and cannot be adjusted at the same time in order to reduce the mass of the whole vehicle as much as possible. One frame can only be used for one vehicle body. On the automobile frame, the frame can be adjusted only by individual parameters at most, and the multi-parameter adjustment of the front wheels cannot be realized.
