Abstract
The utility model relates to a transmission shaft assembly which comprises a first half shaft, a second half shaft and a universal joint. The first half shaft and the second half shaft are connected through the universal joint, the universal joint comprises a first cross shaft and a second cross shaft, the first cross shaft and the second cross shaft are connected through a connection fork, the diameter of the first half shaft is 32-42mm, the length of the first half shaft is 192-202mm, the diameter of the second half shaft is 34-45mm, and the length of the second half shaft is 1400-1407mm. The transmission shaft assembly is simple in structure, enables transmission shafts to be large in power, has the advantages that the half shafts are long in length, thin in diameter and the like, further effectively solves form and location tolerance and guarantees coaxiality.
Description
Technical field
The utility model belongs to the automotive industry technical field, specifically relates to a kind of driving-shaft assembly.
Background technique
Transmission shaft is made up of central siphon, telescopic cover and universal joint.Transmission shaft (Drive Shaft) connects or assembles every accessory, and circular object accessory removable or that rotate, generally all uses light and the good alloy steel pipe of resistance to torsion is made.Car to preposition engine rear wheel drive is the axle that the rotation of speed changer is passed to main reducing gear, and it can be that several joints are connected by universal joint.It is the solid of rotation of a high rotating speed, few supporting, so its dynamic balancing is vital.Truck drive shaft mainly is used in fuel tank, refuelling truck, and the sprinkling truck, suction-type sewer scavenger, fecal suction truck, fire-fighting truck, high-pressure sewer flushing vehicle, road obstacle clearing vehicle, high-altitude operation vehicle is on the vehicles such as refuse collection vehicle.
Big-powered tractor is the agricultural equipment technology-intensive product, is the important symbol of estimating a national agricultural equipment technical merit.Big-powered tractor is mainly for the protection of deep ploughing and the multiple operation of property farming and multiple operation; improve soil structure, large-scale agriculture improves operating efficiency; improve peasant income, develop novel big-powered tractor to improving level of agricultural production, promoting that new countryside construction has important function.
Present domestic tractor market is mainly based on fraction horsepower, and big-powered tractor is mainly external several big giant's monopolization, has promoted cost greatly; In addition, characteristics such as it is long that general big-powered tractor transmission shaft has semiaxis length, and diameter is thin are limited by traditional equipment condition, can't make obtaining 4 wheel driven high-power transmission shaft.
The model utility content
In order to solve problems of the prior art, the utility model provides a kind of 4 wheel driven high-power driving-shaft assembly.
A kind of driving-shaft assembly, comprise first semiaxis, second semiaxis and universal joint, connect by universal joint between described first semiaxis and second semiaxis, described universal joint comprises first cross axle and second cross axle, connect by clevis between described first cross axle and second cross axle, the diameter of described first semiaxis is 32～42mm, and length is 192～202mm; The diameter of described second semiaxis is 34～45mm, and length is 1400～1407mm.
Preferably, the centre distance between described first cross axle and second cross axle is 60～70mm.
Preferably, the cross direction of described first cross axle is provided with first spindle nose, and described first spindle nose is arranged with first axle sleeve outward; The cross direction of described second cross axle is provided with second spindle nose, and described second spindle nose is arranged with second axle sleeve outward.
Preferably, be connected by first needle roller between described first axle sleeve and first spindle nose, be connected by second needle roller between described second axle sleeve and second spindle nose.
This difficulty of processing of the utility model mainly is clevis and semiaxis.Clevis adopts disposable boring, bore hole, cuts the jump ring groove, efficiently solves form and position tolerance; The Vehicle Processing of semiaxis divides rough turn twice, straightening, twice of half finish turning, straightening, and twice of finish turning, straightening have effectively guaranteed coaxality.
The utility model is simple in structure, has given the characteristic of transmission shaft high-power; Characteristics such as it is long not only to have semiaxis length, and diameter is thin, and efficiently solve form and position tolerance and guaranteed coaxality.
