Description
Technical field
The utility model is related to automotive field, and more particularly to one kind possesses automobile drive axle differential axle and power transmission shaft dual-use function
Wheel side power transmission shaft.
Background technology
Breakaway-element drives vehicle bridge to be structurally characterized in that vehicle bridge makes disconnection, and the part such as power assembly and differential mechanism is fixed on
On vehicle body or subframe, reduction nonspring carried mass, therefore the ride comfort of the structure with preferable traveling of breakaway-element driving vehicle bridge,
The comfortableness of seating.
When drive axle uses breakaway-element, to ensure the coordination of motion, the power transmission shaft for being transferred to two sidecar wheels must be taken
Universal driving device.Modern Car either all widely used this structure of forerunner or rear-guard.
The transmission system of general car is constant-velocity transmission shaft, and its feature is to accomplish constant speed in the case of angle change
Transmission, by being limited by structure, transmitting torque is limited, and cost is higher.
But used as divided axle it is then few in medium-sized and above vehicle, mainly due to car, truck driving force
Compare larger, operating mode is increasingly complex with respect to car, therefore requirement to power transmission shaft is higher, it is desirable to the transmission of power transmission shaft energy constant speed
Larger moment of torsion, and the selection of existing high pulling torque constant-velocity transmission shaft is little, cost is also very high, and these factors also constrain breakaway-element
Extensive use of the drive axle on large and medium bus.
Utility model content
The purpose of this utility model is the above-mentioned not enough and defect for prior art, there is provided one kind wheel side power transmission shaft,
To solve the above problems.
The technical problem that the utility model is solved can be realized using following technical scheme：
Wheel side power transmission shaft, it is characterised in that including semiaxis, described semiaxis one end and half method of principal axes being connected on drive hub
Orchid connection, the other end of the semiaxis is connected by the first universal joint with one end of a power transmission shaft, the other end of the power transmission shaft
It is provided with the second universal joint to be connected with power assembly.
In a preferred embodiment of the present utility model, the middle part of the semiaxis passes through bearings in axle tube
It is interior.
In a preferred embodiment of the present utility model, the sleeve pipe of the power transmission shaft is stretching structure.
In a preferred embodiment of the present utility model, first universal joint is the fixed cross-axle universal shaft of FE Tiler
Section.
In a preferred embodiment of the present utility model, the other end of the semiaxis is carried to universal with described first
Save half yoke of connection.
As a result of technical scheme as above, power is transferred to take turns side by power transmission shaft, semiaxis and half shaft flange, drives
Vehicle is travelled, and first, second universal joint is adapting to the change of angle.It is disconnected that the utility model efficiently solves medium-sized and above load
The technology barrier of torque effectively transmission, is promoted the use of to vehicle using divided axle in the transmission of open type drive axle power, is dropped
Underneath drive system cost, the arrangement for improving comfortableness or new energy vehicle power all brings technological break-through.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of embodiment of the utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face is expanded on further the utility model.
Wheel side power transmission shaft shown in Figure 1, including semiaxis 100, the first universal joint 200, power transmission shaft 300, second is universal
Section 400, half shaft flange 500.To carry semiaxis fork structure, one end of semiaxis 100 is connected semiaxis 100 with half shaft flange 500,
Half shaft flange 500 is connected with driving wheel hub again, and the other end of semiaxis 100 passes through half yoke of itself and the phase of the first universal joint 200
Even.By bearings in axle tube 101, the first universal joint 200 connects with one end of power transmission shaft 300 at the middle part of semiaxis 100
Connect, power transmission shaft 300 is connected by the second universal joint 400 with power assembly.
The first universal joint 100 in the present embodiment is the fixed Hooke's joint of FE Tiler, the fixed cross axle ten thousand of FE Tiler
Small, convenient disassembly, reliable operation to section radial dimension.Conventional semiaxis is the coupling bolt that semiaxis and wheel hub are backed out from wheel side,
Semiaxis is extracted out from axle tube, and takes turns side semiaxis due to being limited by universal joint, can only dismounted from inner side.And FE Tiler is solid
Fixed pattern Hooke's joint can facilitate universal joint to dismount.Simultaneously because breakaway-element drives, the radial dimension of universal joint will be straight
The length of influence semiaxis is connect, if radial dimension is bigger, semiaxis will be more long, will influence entirely to take turns tearing open for side power transmission shaft
Dress, therefore the fixed Hooke's joint of the small and controllable FE Tiler of radial dimension meets this requirement.
The sleeve pipe of the power transmission shaft 300 in the present embodiment is stretching structure, for compensating the change of length when vehicle is beated.
During utility model works, power assembly is typically connected with vehicle body, and power output is by power transmission shaft 300, semiaxis 100
It is delivered to wheel hub to drive vehicle with half shaft flange 500, because the bounce of vehicle body and the bounce of wheel hub are asynchronous, therefore first,
Second universal joint 200,400 is adapting to the change of angle.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the utility model spirit and scope are not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed the utility model.The utility model
Claimed scope is by appending claims and its equivalent thereof.
