Abstract

The invention discloses an integrated sub-frame for a formula racing car. The integrated sub-frame includes a car body main frame, independent suspension assemblies are arranged on the both sides of the rear portion of the car body main frame, each independent suspension assembly includes a rear pillar connected to a rear suspension core through a bearing, a sub-frame body is also arranged on therear position of the car body main frame, the upper portion of each rear pillar is provided with an upper V-shaped fork arm through a first pin joint in a hinged manner, one top end, far away from thecorresponding first pin joint, of each upper V-shaped fork arm is hinged to the sub-frame body, and the other top end, far away from the first pin joint, of each upper V-shaped fork arm is hinged tothe car body main frame; and the lower portion of each rear pillar is provided with a lower V-shaped fork arm through a second pin joint in a hinged manner, one top end, far away from the second pin joint, of each lower V-shaped fork arm is hinged to the sub-frame body. The sub-frame body is arranged, the sub-frame body and the car body main frame are used for sharing action force on the independent suspension assemblies, the strength and the bearing force of the whole car frame are effectively improved, the racing car frame is not prone to deformation, and the good operation stability is achieved.

Description

technical field [0001] The invention relates to the technical field of racing cars, in particular to an integrated sub-frame for formula racing cars. Background technique [0002] The frame is an important base component in a formula car, which supports and connects the various system assemblies of the car to keep it in a relatively correct position. At the same time, the frame also bears the load from the inside of the racing car and the impact from the tires through the suspension, so the frame must have sufficient strength and rigidity. While meeting the use requirements, lightweight is also an important part of the frame design. At present, the frames of formula racing cars are mostly truss structures, which usually cannot meet the requirements of strength and stiffness under the condition of light weight, resulting in easy deformation of the frame. Contents of the invention [0003] The object of the present invention is to provide an integrated sub-frame for formul...
