Problems solved by technology
Once the frame is not rigid enough, the handling will be affected
Just imagine that the front wheel has a time difference when turning due to the deformation of the frame, or the poor ground contact between the tire and the road affects the tracking and grip, etc., which will definitely make the maneuverability unable to perform at the original level.
[0004] However, the existing vehicle frame, especially its longitudinal beam, has low anti-twisting performance for large passenger vehicles, and poor driving comfort and stability.

Embodiment Construction
[0017] Such as figure 1 As shown, an auxiliary spring suspension type passenger car longitudinal beam includes a longitudinal beam frame body 1, and a main fixed beam 2 is arranged in the longitudinal beam frame body 1. Fixed triangular fin 3 is arranged. At the same time, auxiliary spring suspensions 4 are connected between the fixed triangle wings 3 . Moreover, the auxiliary spring suspension 4 adopted in the present invention is provided with a mounting assembly.
[0018] In view of a preferred embodiment of the present invention, installation through holes 5 are distributed on the longitudinal beam frame body 1 , and the fixed delta fins 3 are screwed to the longitudinal beam frame body 1 . In this way, the most appropriate installation position of the fixed delta wing 3 can be selected according to the actual length of the stringer frame body 1 . Thereby, the auxiliary spring suspension 4 can be distributed in a better position, and the rigidity of the whole longitudin...

The invention relates to a longitudinal beam for auxiliary spring suspension type passenger cars, which comprises a longitudinal-beam frame body, and the inside of the longitudinal-beam frame body is provided with a main fixed cross beam; and the longitudinal beam for auxiliary spring suspension type passenger cars is characterized in that fixed delta wing panels are arranged on the longitudinal-beam frame body, auxiliary spring suspensions are connected between the fixed delta wing panels, and each auxiliary spring suspension disclosed by the invention is provided with a mounting assembly. Therefore, in the running process of a passenger car, the occurrence of noises caused by that the longitudinal beam is not stressed uniformly can be effectively avoided; and because the auxiliary spring suspensions can be distributed in the longitudinal-beam frame body in a multi-set mode, and can be fixedly connected by the delta wing panels, the gradual stiffness of the longitudinal-beam frame body can be increased.
Description
technical field [0001] The invention relates to a longitudinal beam, in particular to an auxiliary spring suspension type passenger car longitudinal beam. Background technique [0002] The frame is also called the girder. The base body of the car is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels via the suspension device, the front axle, and the rear axle. It has sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. [0003] The rigidity required by the frame is actually built on the deformation resistance of the frame, that is, the frame's resistance to bending or twisting due to external forces. Once the frame rigidity is insufficient, the handling will be affected. Imagine that there is a time lag when the front wheels turn due to the deformation of the frame, or the poor ground contact between the tires and the road affects the tracking and grip, etc., which will definite...
