Abstract
The utility model relates to a hanger frame type double-universal joint transmission shaft for an automobile, comprising a transmission shaft, a main transmission shaft, and a hanger frame type middle support assembled on the driving movable shaft, wherein, a cross shaft type universal joint formed from that the front end of a middle transmission shaft and a hollow shaft pipe are welded together is hinged with a spline slide fork which can directly form a slide pair with the output shaft of a speed changer. A torsional vibration damper is assembled on the spline slide fork, the rear end of the middle transmission shaft is connected with the main transmission shaft with double universal joints by a flange. The hanger frame type double-universal joint transmission shaft for an automobile has compact structure, easy processing, and low manufacturing cost. The hanger frame type double-universal joint transmission shaft for an automobile is reasonably matched with an integral vehicle, and the performance requirement of the integral vehicle is easy to achieve.
Description
The utility model relates to a kind of propeller-shaft that is used for, and is specially adapted to the nose suspension type double jaw joint propeller-shaft on SG1020 minitruck and remoulded car chassis thereof.
Propeller-shaft is the vitals in the automotive transmission, and it connects between change-speed box and the drive axle.Determining of transmission shaft basic specification by the automobile composition design decision, it must with the car load rational Match, could satisfy the vehicle performance requirement.The transmission shaft basic specification of different automobile types is different, and its basic structure is close.Existing transmission shaft often adopts the universal joint center cross to form enclosed or open type universal-shaft drive.Transmission shaft generally adopts hollow central siphon for improving its critical speed, but the locating surface at existing central siphon and weld yoke pressing position is shorter, influences its service life.Weld yoke adopts the forging structure, though material is good but manufacturing cost is higher, higher to the small batch production cost, when transmission output shaft is longer to the distance between the drive axle imput shaft, adopt tween drive spindle and two sections assemblies of main driving axle, for guaranteeing propeller shaft length variable quantity, the sliding type type of belt drive that the main driving axle assembly often adopts the spline cliding yoke to match with castellated shaft.This ground configuration formula is complicated, safeguards inconvenient.Can occur torsion oscillations in some transmission system and under some operating mode, resonance effect occur, influence the transmission shaft normal operation.
The purpose of this utility model provides a kind of nose suspension type double jaw joint propeller-shaft, and its compact conformation is easy to processing, and it is low to make cost, and is reasonable with the car load coupling, is easy to reach the vehicle performance requirement.
The purpose of this utility model is achieved in that this device comprises transmission shaft and main driving axle and assembling nose suspension type center support thereon, the cardan universal joint of tween drive spindle front end and hollow central siphon weld together wherein, be hinged with can be directly and transmission output shaft form the spline cliding yoke of sliding pair, be assembled with torsional balancer on the cliding yoke, the intermediate drive shaft rear end utilizes flange and the main driving axle that has double jaw joint to join.
Because the utility model adopts and cardan universal joint pivotally attached spline sliding pair is direct and transmission output shaft joins, so can be when guaranteeing that transmission shaft has the sufficient length variable quantity, also to the functional reliability that improves transmission shaft critical speed and parts and good result is all arranged service life.This axle and car load coupling rationally satisfy the vehicle performance requirement fully.Because of its designs simplification, adopt the main driving axle of non-sliding type band double jaw joint, so handling ease, installation, maintenance is all very convenient, obviously cuts down finished cost.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure scheme drawing of the present utility model.
Describe concrete structure of the present utility model in detail according to Fig. 1.This device is that for satisfying the vehicle performance requirement, it adopts two transmission shafts to constitute according to the decision of the calculation for layout on minitruck and remoulded car chassis thereof.Tween drive spindle comprises parts such as spline cliding yoke 1, cardan universal joint 4, weld yoke 6, coupling spindle 8, central siphon 7, nose suspension type center support 10, flange 11.Main driving axle comprises central siphon 7 and welds the cardan universal joint 5 at its two ends.Wherein tween drive spindle be welded on be hinged with on the universal-joint 5 of hollow central siphon 7 one ends can be directly and transmission output shaft form the spline cliding yoke 1 of sliding pair.Secondary little modulus, normal shift, the involute teeth of adopting of free-sliding spline is meshed.It has auto-centering, the flank of tooth and advantage such as contacts.The tween drive spindle other end is assembled with flange 11, is assembled with rubber bush in the nose suspension type center support on the tween drive spindle, also is assembled with torsional balancer 2 and blanking cover on the spline cliding yoke 1.Universal-joint 4 adopts snap ring 5 to carry out the location, inboard.Center support is equipped with cover of dust 9 outward.Main driving axle does not adopt traditional sliding type transmission, and adopts the drive mechanism of non-sliding type band double jaw joint, promptly directly uses central siphon 7 and two cardan universal joint 4 weld togethers.Flange yoke 12 1 ends at its two ends are connected with the flange 11 of intermediate drive axle head, and the other end is connected with the drive axle imput shaft.During installation, two center crosss must be in same plane, and should rotate flexibly.Above-mentioned spline cliding yoke 1, flange yoke 12, weld yoke 6 each part all adopt the precision casting manufacturing, and without forging, both can guarantee the parts quality, again cost-cutting greatly.The length of each part pressing spots localization face is obviously greater than the length of respectively pitching the part locating surface in the prior art.
The utility model adopts above-mentioned brand new structure design, and it satisfies the vehicle performance requirement except that guaranteeing, has improved the functional reliability and the service life of parts preferably.Realized simultaneously cushioning the peak impact load in the transmission system effectively, reduced the torsion oscillations in the transmission system and eliminate the possibility that resonance effect takes place in some operating mode underdrive system.
