Embodiment Construction

[0021] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0022] The following describes in detail a design method for turning to a trapezoidal platform.

[0023] According to the embodiment of the present invention, the steering trapezoid platform design method may include: designing a first steering trapezoid suitable for a first type of vehicle, the first steering trapezoid makes the maximum inner steering angle of the first type of vehicle be α1, and the maximum outer steering angle is α2.

[0024] Design a second steering trapezoid suitable for a second type of vehicle with a maximum inner steering angle of α1 and a maximum outer steering angle of α2, the first steering trapezoid has a first trapezoid arm, and the second steering trapezoid has a second trapezoid The arm of the second trapezoid is the same as the arm of the first trapezoid. In other words, the...

Abstract

The invention provides a platformization design method of steering trapezoids. A first steering trapezoid suitable for a first vehicle-type vehicle is designed, the first steering trapezoid makes themaximum internal steering angle of the first vehicle-type vehicle be alpha 1 and the maximum external steering angle be alpha 2, and the first steering trapezoid is provided with a first trapezoid arm; and a second steering trapezoid suitable for a second vehicle-type vehicle is designed, the maximum internal steering angle of the second vehicle-type vehicle is alpha 1, the maximum external steering angle is alpha 2, the second steering trapezoid is provided with a second trapezoid arm, and the second trapezoid arm and the first trapezoid arm are the same, wherein the first vehicle-type vehicle and the second vehicle-type vehicle are different, and the first steering trapezoid and the second steering trapezoid share a production platform. In this way, the second steering trapezoid can be designed according to the first steering trapezoid, research and development of the steering trapezoid of the new vehicle model can be reduced, the research and development time and cost can be reduced, design defects can be avoided, and the research and development cycle of the vehicles can be shortened.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a steering trapezoidal platform design method. Background technique [0002] The increasing demand for diversification of automotive products continues to pose challenges to costs and cycles. The steering system is one of the key systems of the chassis, and its steering trapezoidal design is directly related to the vehicle kinematics performance and suspension characteristics. In the past, in the design of automobile products, it was only designed and developed for a certain model, and the steering system of the modified car, including the steering trapezoid, remained basically unchanged. [0003] However, when it comes to different types of new models, the cost and cycle need to be reinvested, and the steering trapezoid needs to be redesigned. For example, if an SUV has been designed and a sedan needs to be launched, the sedan needs to be developed as a new model, and its ste...
