The present application belongs to the technical field of automobile suspension, and relates to a regulating device, a multi-link suspension, a vehicle and a multi-link suspension design method. The regulating device is connected between a subframe and a longitudinal swing arm of the multi-link suspension, and comprises a regulating bolt, a regulating nut, a regulating washer and a first regulating support. The first regulating support is provided with a first arc-shaped rack and a first arc-shaped hole. The shank of the regulating bolt passes through the longitudinal swing arm, the first arc-shaped hole and the regulating washer. The regulating washer is fixed on the regulating bolt, and the outer ring of the regulating washer is provided with a gear ring engaged with the first arc-shaped rack. When the regulating nut is loosened, the regulating washer is driven to move along the first arc-shaped rack by rotating the regulating bolt, so that the shank of the regulating bolt slides along the first arc-shaped hole, and the relative position of the subframe and the longitudinal swing arm is adjusted, so as to realize the adjustment of the pitch center of the multi-link suspension. The regulating device can reduce the development time and cost of repeated production of sample parts and chassis adjustment.

By means of the treatment scheme, the assembling efficiency and precision of the engine support of the multi-connecting-rod suspension structure are improved.

Various suspension systems for vehicles are described that preferably comprise a multi-link suspension where one or more of the links can move independently of the other links. The multiple independent links are connected to an upright, vertical load reaction that is decoupled from horizontal load reaction, thus delivering a more comfortable ride and reduced feedback to the driver or operator of the vehicle. By eliminating that external feedback using the inventive subject matter discussed herein, vehicles can be safer and easier to control in all circumstances.

This invention relates to the field of intelligent machine technology, specifically to a suspension-adaptive magnetic adsorption pipe-climbing robot, comprising a vehicle body, front and rear drive mechanisms, a control module, sensing devices, and permanent magnet adsorption wheels. The front vehicle body is connected to the upper vehicle body via a yaw-rotation joint and is equipped with a multi-link suspension adaptive mechanism, which can passively adapt to changes in pipe curvature to ensure full contact adsorption of the magnetic wheels. The drive mechanism uses a gear transmission set to drive four permanent magnet adsorption wheels respectively. The control module detects the attitude of the front vehicle body in real time and adjusts the speed of each wheel in a closed loop to achieve motion synchronization and path tracking. This invention effectively solves the problems of adsorption instability, motion stagnation, and trajectory deviation caused by "single wheel suspension" in traditional robots in variable curvature pipes by combining mechanical adaptation and active control. It significantly improves the robot's passability, motion stability, and reliability of inspection operations in complex pipe environments such as bends and sharp corners.

The utility model relates to the technical field of vehicle chassis, in particular to a space-enlarged shock absorber sinking type rear suspension structure for a new energy vehicle. The multi-connecting-rod suspension structure comprises a frame and multi-connecting-rod suspension structures arranged on the two sides of the frame correspondingly. The multi-connecting-rod suspension structure comprises a steering knuckle, a lower control arm, a steering gear and an upper control arm, wherein one end of the steering gear is connected to the middle of the frame, and the other end of the steering gear is connected to the upper portion of one end of the steering knuckle; one end of the upper control arm is connected to the top of the front side of the frame, and the other end of the upper control arm is connected to the middle of the steering knuckle; one end of the lower pull arm is connected to the bottom of the rear side of the frame, the other end of the lower pull arm is connected to the bottom of the other side of the steering knuckle, one end of the upper pull arm is connected to the top of the rear side of the frame, and the other end of the upper pull arm is connected to the top of the other side of the steering knuckle. The shock absorber has the advantages that the height of the upper point of the shock absorber is effectively reduced, and the comfort of the whole vehicle is not affected. A large space is released for arrangement in the lift car, and the bearing pressure of the lower control arm is effectively reduced due to the fact that the lower point is installed on the steering knuckle.
