Abstract
The utility model provides an axle lifting device and an automobile. The axle lifting device is used for lifting axles and comprises a fixing device, a lifting device and at least two suspending parts. The fixing device is fixedly connected with a chassis, and the lower ends of the suspending parts are used for suspending the axles and driving the axles to be vertically lifted along with lifting of the lifting device. The automobile provided with the axle lifting device can enable a tire on the lifting shaft to not contact with the ground or transfer load to other shafts through air sac expansion during driving. The axle lifting device can save fuels during no-load running of automobiles, reduces loss of tires and other elements and allows the load to be redistributed on fewer tires under the condition.
Description
Technical field
The utility model relates to jacking system, particularly, relates to and a kind ofly for elevator belt, the truck of mechanical type suspension and the bont of trailer asessory shaft is arranged.
Background technology
For the vehicle of goods transport be by a plurality of axles and tire by load distribution in ground.For heavy duty, it is necessary sharing load with more axle and tire, also meets rules.In general, under condition of loading vehicle must turn to, driving and asessory shaft.Yet, when unloaded, vehicle only needs a small amount of axle and tire, promotes as much as possible asessory shaft, is convenient to like this capable of saving fuel oil, reduce the loss of tire and miscellaneous part.
When the tire kiss the earth, rolling resistance can produce two kinds of impacts to vehicle.Major effect is to carry out towing vehicle by energy consumption, can directly be interpreted as fuel oil consumption.Another kind of impact is tire wear, when continuous rolling ground friction and mainly produce in the turning process, because tire can not ideally be consistent with the curve that travel.If promoted tire, these two kinds of impacts can be avoided, and vehicle mobility can improve, and reduces tire and fuel oil loss simultaneously.
