Problems solved by technology

Although air suspension and oil-pneumatic suspension have superior performance and can conveniently realize different body height control, they need external energy supply, and their system structure is complex, costly and not widely applicable.
Although the self-supply pump system can automatically adjust the suspension stroke that changes with the load after several bumps of the vehicle through the hydraulic system, so that the suspension stroke is always kept in the middle position, and does not require external energy supply, it is easy to modify the car, but it is not applicable For heavy-duty or low-rigidity suspension occasions, its hydraulic structure is complicated, the cost is high, and maintenance is inconvenient

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] 1. in figure 1 In the shown embodiment, the suspension stroke of the present invention automatically adjusts the formula 1 / 4 vehicle model mainly by: vehicle body (1), wheel (2), compression spring (3), automatic centering device (4), damper ( 5) and other parts, wherein: the compression spring and the automatic centering device are connected in parallel with the damper and installed between the vehicle body and the wheel. Its working principle is: using the up and down motion of the vehicle suspension, through the reciprocating motion mechanism, intermittent motion mechanism, anti-reversal mechanism and rolling screw transmission mechanism of the automatic centering device, the upper connection end of the compression spring is driven relative to the stroke according to the static load. Points do reciprocating intermittent motions up and down with unequal ampli...

Abstract

The present invention relates to a mechanical vebration-absorbing suspension strock automatic midpoint regulator. Said midpoint regulator includes reciprocating motion mechanism, intermittent motion mechanism, anti-reversion mechanism and rolling spiral driving mechanism. Said invention also provides its working principle, and can utilize full-mechanical mode to automatically retain the suspension strock be in midpoint position.

Description

Technical field [0001] The invention relates to a seat (or vehicle) suspension stroke (or height) automatic adjustment device, in particular to a suspension stroke mid-point retainer which is automatically realized by a full-mechanical method and has a vibration-absorbing function. Background technique [0002] The traditional seat suspension stroke centering device adopts a manual sliding screw transmission mechanism. Due to the large friction resistance of the nut and screw pair and low transmission efficiency (generally 30-40%), in order to cooperate with the handwheel drive, it must be installed to save labor. Mechanisms (such as levers or gear sets, etc.). Although its structure is simple, its performance is reliable, and its cost is low, it is not suitable for occasions where passengers are frequently replaced due to manual adjustment, and its durability is limited by the life of the hydraulic shock absorber. [0003] The traditional vehicle height automatic adjustmen...
