Device and design method for realizing rapid connection of frame body with different suspensions

Abstract

The invention belongs to the automobile field and particularly relates to a device and design method for realizing rapid connection of a frame body with different suspensions. The method includes the following steps of 1. defining suspension design space, 2. setting uniform installing points; 3. performing virtual assembling and analysis; 4. designing an installing plate; 5. designing the connecting rack of a base; and 6. designing the support of the base. The connection device can guarantee the connection of suspensions in different types with the frame body, namely a test simplified vehicle body structure having adjustable parameters of wheelbase, wheelspan, axle load distribution, body rigidity and can be matched with different power devices, steering systems, and brake systems, the hard spot installation precision is guaranteed, and the difficulties of the suspensions in different types in the test can be solved.

Description

technical field [0001] The invention belongs to the field of automobiles, and specifically relates to a device and a design method for realizing quick connection between a vehicle body and a suspension. Background technique [0002] The performance test of the current suspension requires a special test vehicle for a specific suspension. When the design of the suspension changes, especially when the hard point position changes, the test vehicle needs to be adjusted accordingly. In the actual process , It is quite cumbersome to adjust the vehicle, and the workload is relatively large, which makes the suspension test cycle relatively long, which is not conducive to the suspension design work. In addition, for suspensions of different configurations, their installation positions are not fixed. Car companies need to set up special test vehicles for specific suspension types to complete the performance test of the suspension, which makes the development cost of the suspension hig...

[0002] The performance test of the current suspension requires a special test vehicle for a specific suspension. When the design of the suspension is changed, especially the position of the hard point changes In the actual process, it is quite cumbersome to adjust the vehicle, and the workload is relatively large, which makes the suspension test cycle relatively long, which is not conducive to the suspension design work.

In addition, for suspensions of different configurations, their installation positions are not fixed

Car companies need to set up special test vehicles for specific suspension types to complete the performance test of the suspension, which makes the development cost of the suspension higher and the development cycle longer, which is not conducive to product research and development.
