The utility model adopts the above structure can swing trailer that the gasbag hung, the gasbag hangs and connects the wheel assembly through horizontal swing mechanism and vertical swing mechanism respectively, can hang the basis of original performance on keeping the gasbag, has realized the horizontal swing and the vertical hunting of axletree.
Description
Technical Field
The utility model relates to a special type transportation equipment technique especially relates to a trailer that can swing gasbag and hang.
Background
A semi-trailer refers to a trailer that is towed by a semi-tractor and that has a substantial portion of the maximum total mass of the trailer borne by the tractor. Therefore, suspension systems are often used to reduce tire wear;
the suspension system is a general term for all force-transmitting connecting devices between the frame and the wheels of the automobile, and has the functions of transmitting force and torsion acting between the wheels and the frame, buffering impact force transmitted to the frame or the automobile body from an uneven road surface, and attenuating vibration caused by the impact force so as to ensure that the automobile can run smoothly.
The air bag has good suspension comfort, and a lifting device is easy to add, so that an axle can be lifted when the vehicle is in no load, the landing area of the tire is reduced, and the abrasion (especially the abrasion during steering and braking) and the oil consumption of the tire are reduced. However, most of the existing airbag suspension structures are through-shaft structures, and airbags are arranged on opposite sides of each shaft, so that the airbag suspension structure can not realize transverse swinging and longitudinal swinging functions.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a but trailer that swing gasbag hung, the gasbag hangs and connects the wheel assembly through horizontal swing mechanism and vertical swing mechanism respectively, can keep the gasbag to hang on the basis of original performance, has realized the horizontal swing and the vertical hunting of axletree.
In order to achieve the purpose, the utility model provides a but trailer that swing gasbag hung, including trailer, wheel assembly with install in the gasbag of the longeron bottom of trailer hangs, the gasbag hang still respectively through horizontal swing mechanism and vertical swing mechanism with the wheel assembly is connected.
Preferably, the airbag suspension comprises a height valve and a bearing airbag communicated with the height valve, the bearing airbag comprises a transverse driving airbag and a longitudinal driving airbag, and the transverse driving airbag and the longitudinal driving airbag are arranged on the longitudinal beam perpendicularly.
Preferably, the wheel assembly comprises an axle arranged below the trailer and wheels rotatably arranged on the axle, the transverse swinging mechanism comprises a swinging sliding block with one end connected with the output end of the transverse driving air bag, and the other end of the swinging sliding block is connected with the side part of the axle.
Preferably, the longitudinal swing mechanism comprises a swing arm with one end rotatably connected with the bottom end of the longitudinal beam through a fixed support, the other end of the swing arm is connected with one end of a bearing bracket, and the other end of the bearing bracket penetrates through the bottom end of the axle and then is connected with the output end of the longitudinal driving air bag.
Preferably, a shock absorber is further connected between the swing arm and the longitudinal beam.
Preferably, the air bag suspensions are arranged on longitudinal beams on two sides symmetrical to the central line of the trailer.
Preferably, the trailer type is one-line two-shaft, two-line four-shaft, three-line six-shaft or four-line eight-shaft.
Therefore, the utility model adopts the above structure can swing the trailer that the gasbag hung, the gasbag hangs and connects the wheel assembly through horizontal swing mechanism and vertical swing mechanism respectively, can keep the gasbag to hang on the basis of original performance, has realized the horizontal swing and the vertical hunting of axletree.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
