Problems solved by technology

[0005] However, the existing double-wishbone suspension usually performs a single adjustment to the geometric position of the A-shaped wishbone according to the needs of the vehicle, which can meet the comfort requirements of passengers and drivers in most road conditions, but when the car is During emergency braking, the internal load of the vehicle is transferred back and forth, which will cause the front of the car to nod and the rear to tilt up, or the front to tilt up and the rear to squat down when the vehicle accelerates in an emergency, which will cause the car to The driver and passengers feel uncomfortable, which affects the user experience. Therefore, the single geometric adjustment of the double-wishbone suspension is difficult to meet the comfort of the passengers in the car.

Embodiment 1

[0044] Such as figure 2 As shown, a double wishbone suspension is characterized in that it includes a first wishbone 1, a second wishbone 2 and an adjustment assembly 3, and the adjustment assembly 3 is arranged on the first wishbone 1 and the said first wishbone between the second fork arms 2;

[0045] The adjustment assembly 3 includes a drive part 31, a first push rod 32 and a second push rod 33, one end of the drive part 31 is connected to one end of the first push rod 32, and the other end of the drive part 31 Linked to one end of the second push rod 33;

[0046] The other end of the first push rod 32 is connected with the first fork arm 1, and the other end of the second push rod 33 is connected with the two fork arm 2;

[0047] The driving part 31 is used to push the first push rod 32 to move toward or away from the first fork arm 2, and / or, the drive part 31 is used to push the second push rod 33 to move toward Move towards or away from the second wishbone 2 to adj...

Embodiment 2

[0056] Such as Figure 4 As shown, a double-wishbone suspension automatic adjustment system includes: an acceleration sensor, a control unit and the double-wishbone suspension as described in Embodiment 1;

[0057] The acceleration sensor is used to measure the acceleration of the vehicle;

[0058] The control unit is configured to issue an instruction to adjust the position or height of the double-wishbone suspension according to the acceleration of the vehicle;

[0059] The adjustment assembly 3 is used to adjust the position or height of the double wishbone suspension according to the adjustment instruction issued by the control unit.

[0060] The existing double-wishbone suspension usually performs a single adjustment to the geometric position of the A-shaped wishbone according to the needs of the vehicle, which can meet the comfort requirements of passengers and drivers in most road conditions, but when the car is in an emergency When braking, the front of the car is no...

Embodiment 3

[0070] Such as Figure 6 As shown, a double-wishbone suspension automatic adjustment method is used in the system described in Embodiment 2, and the method includes:

[0071] S01, measuring the acceleration of the vehicle;

[0072] S02, making an instruction to adjust the position or height of the double wishbone suspension according to the acceleration of the vehicle;

[0073] S03. Adjust the position or height of the double wishbone suspension according to the adjustment instruction.

[0074] Through the implementation of the above technical solution, the method of the present invention can automatically adjust the position or height of the double-wishbone suspension under the state of emergency braking or acceleration of the vehicle. The load absorbed by the elastic elements of the frame is partly absorbed by the mechanical structure of the double wishbone suspension, so that the body is more stable, which solves the situation of nodding at the front and raising the rear ...

Abstract

The invention relates to a double-wishbone suspension, an automatic adjustment system and method for a double-wishbone suspension, and the system can, through the adjustment component of the double-wishbone suspension, be able to Automatically adjust the position or height of the double-wishbone suspension, and by changing the geometric characteristics of the suspension, the load originally absorbed by the elastic elements of the suspension is partially absorbed by the mechanical structure of the double-wishbone suspension, thereby making the vehicle body more Stable, which solves the situation that the front of the vehicle nods and the rear tilts up when the vehicle brakes in an emergency, or the front tilts up and the rear squats when the vehicle accelerates in an emergency, which improves the driving experience.

Description

technical field [0001] The invention relates to the technical field of automobile suspension, in particular to a double-wishbone suspension, an automatic adjustment system and method for the double-wishbone suspension. Background technique [0002] Double wishbone suspension is a common active suspension in automobile suspension. It is mostly used in the front suspension of cars that pursue handling. Double wishbone suspension is also called double A wishbone. Its upper and lower A-shaped The wishbone can precisely position various parameters of the front wheel, so that the wheel can be close to the ground, and the strong lateral rigidity also provides good side support. [0003] Such as figure 1 As shown, the instantaneous center point is the virtual intersection of the side extension lines of the A-shaped wishbone of the double-wishbone suspension. The position and height of the glyph wishbone can change the height of the instantaneous center point of the double wishbone...
