Problems solved by technology
Ordinary suspension system vehicles cannot actively adapt to changes in road conditions, and it is difficult to meet production needs
Due to the limitation of the passing capacity of the vehicle suspension system, many equipment cannot enter the work area and can only be transported by manpower. The production efficiency is extremely low, which greatly restricts the development of economic industries in mountainous and other complex road areas.

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] Such as Figure 1 to Figure 9 As shown, the load-bearing multi-purpose cylinder for the pneumatic suspension of the all-electric transmission vehicle chassis of the present invention includes a cylinder body 1, and the bottom of the cylinder body 1 is provided with radial air holes 8 for communicating with the gas circuit. The cylinder body 1 There is a piston shaft 2 that can be stretched up and down inside, and an O-ring 3 is provided on the outer surface of the lower part of the piston shaft 2. The O-ring 3, the cylinder body 1, and the piston shaft 2 form a closed space that can only be adjusted axially. The axial variable load bearing of the piston shaft is realized through the real-time adjustment of the closed-loop air pressure. The stroke range of the piston shaft 2 is 1 mm to 300 mm. The cylinder body 1 is embedded with a pressure sensor, and the pist...

The invention discloses a bearing type multipurpose cylinder for pneumatic suspension of a chassis of an all-electric transmission vehicle. The bearing type multipurpose cylinder comprises a cylinderbody with an air hole and a telescopic piston shaft which is arranged inside the cylinder body, wherein a step is arranged inside an upper port of the cylinder body; a linear bearing structure is arranged between the upper end of the step surface of the cylinder body and the piston shaft, and comprises a gland, a directional limiting sleeve and a dust cover which are sequentially arranged from bottom to top; axial guide grooves are uniformly formed in the inner surface of the directional limiting sleeve and the outer surface of the piston shaft along the circumference; the guide grooves insidethe directional limiting sleeve and the guide grooves outside the piston shaft are aligned one by one; and steel balls are arranged in each group of guide grooves. According to the bearing type multipurpose cylinder, a suspension system has the capability of actively adapting to road conditions, so that the passing property of special road conditions is enhanced, and the bearing type multipurposecylinder is suitable for special road environments of unevenness, large-angle uphill and downhill, soft soil and the like.
Description
technical field [0001] The invention belongs to the technical field of multifunctional vehicles used in special road environments, and more specifically relates to a load-bearing multipurpose cylinder for pneumatic suspension of an all-electric transmission vehicle chassis. Background technique [0002] The mountain operating vehicles currently in use still mainly use the traditional suspension system. The slope of the mountain is large and the road conditions on the ground are complex. Ordinary suspension system vehicles cannot actively adapt to changes in road conditions, and it is difficult to meet production needs. Due to the limitation of the passing capacity of the vehicle suspension system, many equipment cannot enter the work area and can only be transported by manpower. The production efficiency is extremely low, which greatly restricts the development of economic industries in mountainous and other complex road areas. Contents of the invention [0003] The purp...
