Liftable suspension for special vehicles

Abstract

The invention relates to a liftable suspension applicable to special vehicles. The liftable suspension comprises sliding devices and a lifting driving device which are lifted and dropped synchronously and further comprises at least one connecting piece for connecting the sliding devices and the lifting driving device, sliding pieces on the sliding devices and a lifting pushing piece on the lifting driving device are connected with a wheel mounting device, a top cover is arranged at the top ends of the sliding devices, and the lifting driving device is in perpendicular gliding connection with the top cover. The liftable suspension applicable to the special vehicles has a lifting and dropping damping function and a vibration reducing function.

Description

technical field [0001] The invention relates to a suspension of a special mobile machine, in particular to a liftable suspension suitable for special vehicles such as off-road vehicles and agricultural vehicles. Background technique [0002] Suspension is the general term for all force transmission connection devices between the vehicle frame (or load-bearing body) and the axle (or wheel), its function is to transmit the force and torque acting between the wheel and the frame, and Buffer the impact force transmitted to the frame or body from the outside, and reduce the vibration caused by it, so as to ensure that the vehicle can run smoothly. [0003] A typical suspension structure consists of elastic elements, guides, and shock absorbers, while individual structures also have buffer blocks, stabilizer bars, and the like. Elastic elements are also in the form of steel plate elastic elements, air elastic elements, spiral elastic elements, and torsion bar elastic elements. Mo...

Problems solved by technology

Elastic elements are also in the form of steel plate elastic elements, air elastic elements, spiral elastic elements, and torsion bar elastic elements. Modern car suspensions mostly use spiral elastic elements and torsion bar elastic elements, and individual high-end cars use air elastic elements, but this This kind of suspension has complex structure and heavy weight, so it is not suitable for off-road vehicles or agricultural equipment and other mobile devices that require small weight

[0004] Special vehicles such as off-road vehicles and agricultural vehicles should have multiple functions for non-road driving. There are more than 20 kinds of supporting equipment for agricultural vehicles, which can be used for nearly 40 farmland operations, such as rotary tillage, loose soil, fertilization, and weeding. , ditching, soil cultivation, spraying, harvesting, etc., so the pastoral management machine is required to be light in weight, but the existing pastoral management machine does not have the lifting function and vibration reduction, which is not suitable for inter-cultivation and obstacle crossing.
