Problems solved by technology

[0002] The current semi-active suspension of vehicles generally achieves the purpose of reducing vehicle vibration by adjusting the damping coefficient of the shock absorber to change the vibration characteristics of the vehicle suspension device. And the vibration damping effect is limited
Especially for large-tonnage military vehicles, if the damping coefficient is changed, the damping force of the entire vehicle shock absorber may be reduced, so that when the vehicle is driving on a high-frequency gravel road, the temperature of the shock absorber rises rapidly and thus Make the vehicle's vibration damping performance worse, but have a bad effect

Embodiment Construction

[0017] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0018] figure 1 It is a schematic side view of the solution of the present invention, figure 2 It is a schematic half view of the rear view of the solution of the present invention.

[0019] Such as figure 1 , figure 2 As shown, each vehicle suspension assembly of the present invention includes a car body 1, a nut 2, a screw rod 3, a motor 4, a spring 5, a shock absorber 6, a wheel 7, a lower connecting rod 9, an upper cross arm 10, and a lower cross arm 11, wheel 12, support bar 13 forms. Wherein motor 4 two ends are coaxially respectively connected with a screw rod 2, screw rod 2 threads at both ends are reversed and equal pitch, the rotating shaft of motor 4 and screw rod 3 shafts are made coaxial or do not have relative rotation in radial direction, when guaranteeing that motor 4 rotates, The screw rods 2 at both ends rotate at a constant ...

Abstract

The invention discloses a vehicle hanger, comprising an upper cross arm, a lower cross arm, a spring, a shock absorber and the other conventional parts. The vehicle hanger is characterized in that the hanger comprises a motor 4 and a screw stem structure which is arranged systematically, the rotating shaft of the motor 4 is coaxial with a screw stem 3 of the screw stem structure, and the screw stem 3 is driven to rotate by the motor 4. The screw stem 3 is driven to rotate by starting the motor 4, the forward and backward position of a nut 2 is changed, so as to achieve the purposes of adjusting the height of the vehicle to the ground and changing the equivalent stiffness coefficient of the spring 5 in the vertical direction and the equivalent damping coefficient of the shock absorber 6 in the vertical direction, and enable the vehicle to be adaptive to the smoothness of different road surfaces with different driving speeds; and moreover, the static posture of the vehicle can be adjusted by changing the height of the single hanger.

Description

【Technical field】 [0001] The invention relates to a vehicle suspension device, in particular, the invention relates to a semi-active vehicle suspension with the functions of adjusting the height of the vehicle from the ground and damping vibration. 【Background technique】 [0002] The current semi-active suspension of vehicles generally achieves the purpose of reducing vehicle vibration by adjusting the damping coefficient of the shock absorber to change the vibration characteristics of the vehicle suspension device. And the damping effect is limited. Especially for large-tonnage military vehicles, if the damping coefficient is changed, the damping force of the entire vehicle shock absorber may be reduced, so that when the vehicle is driving on a high-frequency gravel road, the temperature of the shock absorber rises rapidly and thus It makes the vehicle's vibration damping performance worse, but it has a bad effect. [0003] The present invention is proposed aiming at the ...
