Embodiment
The technical solution in the present invention is further illustrated with reference to the accompanying drawings and embodiments.
Embodiment 1：
As shown in Figs. 1-2, the present invention proposes a kind of high-strength vehicle cross axle, including cross shaft body 2, is applied in ten
Input shaft 1 inside word shaft body 2 and the connecting pole 3 being arranged on outside cross shaft body 2, specifically：
In the present embodiment, cross shaft body 2 is circular column, and the inner side of cross shaft body 2 is equipped with some fixing grooves 21, fixing groove
21 depth is less than the half of 2 thickness of cross shaft body, avoids influencing its structural strength, and fixing groove 21 and cross shaft body 2
It is coaxially disposed, in the preferable scheme of this implementation, cross shaft body 2 is internally provided with four fixing grooves 21 in crosswise distribution, together
When input shaft 1 correspond to the position of cross shaft connection main body 2 and be equipped with four and the matched fixed chuck 11 of fixing groove 21；Cross axle
The connector 22 that the outside of main body 2 is equipped with four radially and is set in crosswise, the connector 22 is the circular cone of tip outwardly
Shape, in the preferable scheme of the present embodiment, is along the circumferential direction equally spaced to one another between fixing groove 21 and connector 22 and staggers, avoid
Input shaft 1 and connecting pole 3 excessively concentrate the active force of cross shaft body 2, so as to improve stress resistance.
Connecting pole 3 is internally provided with link slot 31 matched with the shape of connector 22 close to 2 one end of cross shaft body,
The integration of the outside of connecting pole 3 is equipped with two pieces of inclined securing plates 32, and securing plate 32 in connecting pole 3 close to 31 one end of link slot
Bottom symmetrical is set, while the width of securing plate 32 is engaged with the thickness of cross shaft body 2 so that when connecting pole 3 is installed on
Securing plate 32 is respectively coated by the surface of cross shaft body 2 from both sides when on connector 22；32 medial surface of securing plate for arc with
Coordinate the shape on 2 surface of cross shaft body so that stiffening piece and 2 intimate surface contact of cross shaft body, 32 lateral surface of securing plate
Be flat shape so as to lift structure intensity, the ability of increase confrontation circumferentially stress, the adjacent securing plate 32 on adjacent connecting pole 3
Between it is closely coupled so that four connecting poles 3 are connected to an entirety, can by securing plate 32 will wherein one connection
Pressure transmission on column 3 circumferentially is into other connecting poles 3, so as to reduce the pressure that an independent connecting pole 3 is subject to.This
In embodiment, the angle between 32 lateral surface of securing plate and connecting pole 3 is 135 °, i.e., two on same root connecting pole 3 piece reinforce
It is in 90 ° between 32 lateral surface of plate, the square of a closing is surrounded between whole securing plates 32 of four connecting poles 3, ensure that
The wherein uniformity of stress.
In the present embodiment, securing plate 32 is equipped with upper and lower perforative connecting hole, and 2 surface of cross shaft body corresponds to connection hole
Equipped with threaded hole, further include and be fixedly connected with the screw of column 3 with threaded hole also cross connecting hole.When mounted, first will be even
The tapered groove alignment connector 22 for connecing 3 bottom of column is inserted into, and adjusts the position of securing plate 32 so that connecting hole and threaded hole pair
Standard, then be fixed with screw, after repetitive operation installs four connecting poles 3, securing plate 32 is complete by the outside of cross shaft body 2
Full cladding, among the 11 alignment and fixation groove 21 of fixed chuck on input shaft 1 finally is inserted into cross shaft body 2, so that by cross
Shaft body 2 is fixed on input shaft 1, that is, completes the installation of cross shaft member, can carry out other operations.The present invention uses split
The power of input shaft 1, is transmitted by formula structure by the cooperation of cross shaft body 2 and connecting pole 3, so that input shaft 1
The power decentralized of upper input, will not produce local excessive stress point, so as to improve the structural strength of cross axle, reduce axis
Head rupture and so on probability, can be according to different automobile types while because split structure is made of different assembling parts
