Structural I-beam is heavy in the prior art, is unfavorable for the light-weighted realization of vehicle；I-beam drop is big, and (two level falls
Difference), and spring carrying block section and middle H-section are highly big, cause the vehicle road clearance small, it is poor by property；I-beam both ends
Fist portion machined lockpin hole, for the locking of I-beam fist portion and stub, cause fist portion intensity decreases；I-beam integrated stress point
Cloth is uneven, and local stiffness is larger, causes vehicle ride comfort and comfortableness poor；I-beam uses symmetric design, causes steering ladder
Shape spindle arm space is restricted, and propons corner is limited.
Utility model content
The purpose of this utility model is：Reduce the weight and cost of I-beam；The drop of I-beam is reduced, improves vehicle and leads to
The property crossed；Cancel fist portion kingpin bore, the intensity in increase fist portion；Solves I-beam integrated stress skewness, local stiffness is larger
Problem, improve vehicle ride comfort and comfortableness；For the reserved bigger space of steering trapezium spindle arm, increase propons turns
Angle.
To realize above-mentioned technical purpose, the utility model provides a kind of propons I-beam, and it includes：I-beam body, plate
Spring bonding pad, fist portion region and axle journal bonding pad, wherein：The middle part of the I-beam body has the hollow out knot of vertical direction
Structure；The upper end width of the leaf spring bonding pad is more than the width of lower end, and has step knot between the upper end and middle part
Structure；And the fist portion kingpin bore in fist portion region connects with stub for interference fit.
As a further improvement, the top and bottom of the I-beam body misplace arrangement in the horizontal.
As a further improvement, it is less than lower end length in steering trapezium side, the upper end length of the I-beam body.
As a further improvement, the beam bottom of the I-beam body is parallel with respect to ground.
As a further improvement, width of the axle journal bonding pad in steering trapezium side is more than the width of opposite side.
As a further improvement, fist portion region only has positive stop lug boss in the opposite side of steering trapezium.
As a further improvement, the positive stop lug boss is in arrive triangle.
As a further improvement, there is transition chamfering between fist portion region and the axle journal bonding pad.
The utility model reduces the weight and cost of I-beam by the adjustment of shape of cross section；Reduce I-beam
Drop, vehicle is improved by property, automobile is tackled more complicated driving cycle.

Embodiment
As shown in Fig. 1 to 7, the utility model provides a kind of propons I-beam 100, and it includes：I-beam body 1, leaf spring
Bonding pad 2, fist portion region 3 and axle journal bonding pad 4, wherein：The middle part of the I-beam body 1 has the hollow out knot of vertical direction
Structure 5；The upper end width of the leaf spring bonding pad 2 is more than the width of lower end, and has step between the upper end and middle part
Structure 6；And the fist portion kingpin bore in fist portion region 3 connects with stub for interference fit.
As a further improvement, the top and bottom of the I-beam body 1 misplace arrangement in the horizontal.
As a further improvement, at steering trapezium side (rear of vehicle traveling direction), the I-beam body 1
Upper end length is less than lower end length.
As a further improvement, the beam bottom of the I-beam body 1 is parallel with respect to ground.
As a further improvement, the axle journal bonding pad 4 is at steering trapezium side (rear of vehicle traveling direction)
Width is more than the width of opposite side.
As a further improvement, fist portion region 3 only has positive stop lug boss 7 in the opposite side of steering trapezium.
As a further improvement, the positive stop lug boss 7 is in arrive triangle.
As a further improvement, there is transition chamfering 8 between fist portion region 3 and the axle journal bonding pad 4.
The utility model reduces the weight and cost of I-beam by the adjustment of shape of cross section；Reduce I-beam
Drop, vehicle is improved by property, automobile is tackled more complicated driving cycle.
As illustrated, the utility model is designed using one-level drop, I-beam drop is reduced, centre uses hollow type knot
Structure, cancel two unnecessary positive stop lug boss, reduce the weight of I-beam；Cancel two level drop, I-beam bottom is into parallel appearance
State, the road clearance of propons is increased, improve passing through property.
Fist portion kingpin bore is with stub using the lock pin locking mechanism in over-surplus fit structure substitution original structure, such I-shaped
Lockpin hole is no longer arranged on beam.
The utility model is carried out using asymmetric design all around, iso-stress design to I-beam major section parameter
Optimization, as shown in each sectional view, can solve the problems, such as that I-beam local stiffness is larger, improve vehicle ride comfort and comfortableness.
Unsymmetric structure before and after the utility model uses, it is reserved more at steering trapezium side (rear of vehicle traveling direction)
Big space, while be so spindle arm and horizontal drawing in the use chamfered mode of fist portion and axle journal junction
Bar provides bigger space, it is possible to achieve the big corner of propons turns to, and reduces the radius of turn of vehicle.
The utility model reduces the weight and cost of I-beam；The drop of I-beam is reduced, vehicle is improved and passes through
Property, automobile is tackled more complicated driving cycle；Cancel fist portion kingpin bore, the intensity in increase fist portion, I-shaped can be extended
The service life of beam；Designed by iso-stress, solve I-beam integrated stress skewness, the problem of local stiffness is larger, change
Kind vehicle ride comfort and comfortableness；For the reserved bigger space of steering trapezium spindle arm, increase propons corner, make vehicle
With smaller radius of turn.
It should be appreciated that the utility model scope of the claimed is not limited to non-limiting embodiments, it should be understood that non-limiting reality
Scheme is applied to illustrate as just example.The desired substantive protection domain of the application is more embodied in independent claims
The scope of offer, and its dependent claims.
