Problems solved by technology

[0003] That is to say, the above-mentioned suspension lifting adjustment device that realizes the suspension height adjustment through the hydraulic structure, the raising or lowering scheme of the vehicle body has changed the total length of the shock absorber, and an external device is connected to the shock absorber, which will change the shock absorber. The force point of the shock absorber affects the life of the shock absorber, and it has no locking mechanism. In order to keep the height constant, it needs to maintain the pressure continuously. Risk of oil leakage and environmental pollution, there is room for improvement

Embodiment Construction

[0045] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0046] Suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel). Suspensions generally include elastic elements, damping elements, force transmission mechanisms or guiding structures, and lateral stabilizing devices. The elastic element, such as the spring 3000, can play the role of buffering, the damping element, such as the shock absorber, can play the role of damping, the force transmission mechanism can play the role of force transmission and guiding, and the lateral stabilizing device can prevent the vehicle body from excessive roll.

Abstract

The invention discloses a suspension lifting adjusting device. The suspension lifting adjusting device comprises an adjusting component. The adjusting component is connected with a spring base of the suspension so that the spring base is driven to move up and down. Through adjusting the position when the spring base moves and the position of a car body, the suspension lifting adjusting device in the embodiment of the invention does not change a stress point of an absorber. In addition, the suspension lifting adjusting device is simple in structure, low in cost and wide in application.

Description

technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to a suspension lifting adjustment device. Background technique [0002] In related technologies, the suspension lifting adjustment device is realized by hydraulic structure. For example, one of the suspension lifting adjustment devices is to add a hydraulic cavity at the upper or lower end of the shock absorber, and pressurize or release the pressure in the hydraulic cavity. The way to change the length of the shock absorber is to raise or lower the body. Another way is to make the connecting bracket connected with the steering knuckle into a sealed cavity, and fix a piston at the lower end of the outer cylinder of the shock absorber, and connect the connecting bracket The formed cavity is divided into upper and lower cavities, and the length of the shock absorber is changed to raise or lower the vehicle body by pressurizing or depressurizing the upper and lower cavities...
