Abstract
The utility model discloses a transmission shaft, comprising a front shaft, a middle shaft and a back shaft, the front shaft and the back shaft adopt spline sleeves to be connected with a rotating shaft of a gearbox, the front shaft and the back shaft respectively adopt universal joints to be connected with the middle shaft, the middle shaft adopts the spline sleeve to be matched and movably connected with a spline shaft, and a fastening screw is arranged on the spline sleeve of the back shaft. As the fastening screw is arranged on the back shaft of the transmission shaft, a support bearing device is added on the front shaft and the back shaft can be fixed by the bearing support, the connection structure of a host and the rotating shaft of the gearbox on a trailer is more reasonable and the connection is more reliable, thus being conducive to improving the safety of vehicle driving.
Description
Technical field
The utility model belongs to transmission part, is specifically related to a kind of transmission shaft that is used for tractor dynamic power.
Background technique
Tractor is a kind of main means of transportation in the rural area, generally all is to utilize main frame and trailer to flexibly connect.The power of main frame is delivered to the trailing wheel of trailer by transmission shaft, can realize four-wheel drive.Rotatingshaft on the auxiliary transmission (being generally 130 main-gear boxs) on the gearbox that existing transmission shaft adopts spline housing and main frame and the trailer is connected.The subject matter that this transmission shaft exists is that the position that is connected with gearbox does not have securing means, is easy to come off when turning round or jolt, and causes accident to take place.
The model utility content
The purpose of this utility model is to provide a kind of and is connected reliably the transmission shaft that fault is few with gearbox.
Realize that above-mentioned model utility purpose technological scheme is: transmission shaft comprises front axle, axis and rear axle, front axle all adopts spline housing to be connected with the rotatingshaft of gearbox with rear axle, front axle adopts universal joint to be connected with axis respectively with rear axle, axis adopts spline housing to cooperate flexible connection with splined shaft, is provided with fastening screw trip bolt on the rear axle spline housing.
Further technological scheme is:
Lean on an end of its spline housing to be provided with the bearing spider that can be fixed on the gear box casing at front axle.
On described rear axle, be provided with bearing spider;
Be provided with dust-proof cover at described axis spline housing and splined shaft joint.
The utility model is in when assembling, front axle and rear axle respectively with the gearbox of tractor main frame and trailer on auxiliary transmission on rotatingshaft be connected after, the fastening screw trip bolt on the rear axle is tightened, the bearing spider on the front axle is fixed on the gear box casing.Because the spline housing on the rear axle reliably is connected by auxiliary transmission rotatingshaft on fastening screw trip bolt and the trailer, the front axle bearing spider is fixed on the gearbox casing of main frame, can play the effect of supporting shaft, dual mode can improve the reliability that antero posterior axis is connected with the gearbox rotatingshaft.When rear axle is longer, the bearing spider on the rear axle can be fixed on the trailer, to increase the reliability that rear axle is connected with the auxiliary transmission rotatingshaft.
The utility model is owing to be provided with fastening screw trip bolt on rear axle, increased bearing support assembly on the front axle, also can rear axle have been fixed by bearing spider, make with main frame and trailer on the linkage structure of gearbox rotatingshaft more reasonable, connect more reliably, help improving travel safety.
Further specify the technical solution of the utility model below in conjunction with accompanying drawing.
