Preceding bridge 100 below with reference to Fig. 1-Fig. 7 descriptions according to the utility model embodiment.
It can be included according to the preceding bridge 100 of the utility model embodiment：Front axle 1 and wheel end assembly 2.
As shown in Fig. 2, the left end and right end of front axle 1 have front axle axle sleeve 11.Specifically, before front axle axle sleeve 11 is is arranged on
The fist shape structure of 1 left end of axis and right end, for being attached with knuckle 21, and is rotatably attached with knuckle 21.
The middle part of front axle 1 is bent downwardly concavity, the purpose is to be minimized engine location, so as to reduce automobile matter
The heart, extends driver's seat, reduces the angle between transmission shaft and transmission output shaft.Specifically, the section of front axle 1 is I-shaped
Shape, thus, can enable front axle bear the pressure of bigger.
Preferably, front axle 1 can by using medium carbon steel through die forging and heat treatment and be made, thus, can make front axle 1 have compared with
Strong strength and stiffness.
With reference to Fig. 1 and Fig. 5, wheel end assembly 2 is separately positioned on the left end and right end of front axle 1, and front-wheel end assembly 2 includes：Turn
To section 21 and wheel hub 22.
Further, as shown in Figure 3-Figure 5, knuckle 21 has knuckle axle sleeve 211, knuckle axle sleeve 211 and front shaft
Set 11 wears connection by connecting stub 3, and plane damping bearing 4 is provided between front axle axle sleeve 11 and knuckle axle sleeve 211.This
Utility model embodiment makes damping good by using plane damping bearing 4, and the ability for absorb impact energy, absorbing vibration is strong,
So that vehicle traveling is more steady, and there is self-lubricating effect, avoid occurring to turn to unstable phenomena impair Vehicular turn safety
Property, while preceding bridge 100 can be avoided to resonate, the impact resistance ability enhancing of bridge before can also making.
Specifically, knuckle 21 is the hinge of wheel steering, generally in fork-shaped.Upper and lower two fork is useful for installation connection stub
3 knuckle axle sleeve 211, has front axle axle sleeve 11 on front axle 1, knuckle axle sleeve 211 is with front axle axle sleeve 11 by being connected stub 3
Connection is worn, and then front-wheel is deflected certain angle around connection stub 3 and makes motor turning.
The function of knuckle 21 is to transmit and bear automotive front load, supports and drives front-wheel to be rotated around connection stub 3
And make motor turning.Under vehicle driving state, it subjects changeable shock loading, it is therefore desirable to which knuckle 21 has very
High intensity.
With reference to Fig. 5, wheel hub 22 is set on knuckle 21.Specifically, wheel hub 22 is set on knuckle axle journal 212, wheel
Hub 22 is used for installing tire.
According to the preceding bridge 100 of the utility model embodiment, the preceding bridge 100 can realize before 100 lightweight of bridge and meet rigidity,
Intensity requirement, and the steering behaviour and braking ability of preceding bridge 100 can be improved, improve drive safety.
Specifically, it is two be spaced apart up and down with reference to Fig. 3 and Fig. 5, knuckle axle sleeve 211, front axle axle sleeve 11 is positioned at upper
Between lower two knuckle axle sleeves 211, plane damping bearing 4 be folded in front axle axle sleeve 11 and following knuckle axle sleeve 211 it
Between.Thus, the rotation of knuckle 21 can be made more smooth, and then makes the rotation of wheel more smooth.
Specifically, plane damping bearing 4 is set on connection stub 3.Thus, connection stub 3 is fed through knuckle axle sleeve
211st, front axle axle sleeve 11 and plane damping bearing 4, and by plane damping bearing 4 it is rotatable be folded in front axle axle sleeve 11 with it is following
Knuckle axle sleeve 211 between, effectively reduce the friction between front axle axle sleeve 11 and knuckle axle sleeve 211, make knuckle 21 around
The rotation for connecting stub 3 is more effortless.
Further, as shown in figure 4, plane damping bearing 4 includes：Outer cover 41, rotating ring 42, stationary ring 43 and damping ring 44, are moved
Ring 42, stationary ring 43 and damping ring 44 are arranged in outer cover 41, and damping ring 44 is located between rotating ring 42 and stationary ring 43.
Specifically, the camber angle of knuckle 21 is 0.4 °.When the camber angle of knuckle 21 is arranged to 0.4 °, vehicle can be made
Meet tire and the rational contact surface in ground under unloaded and full load conditions, and the use for combining plane damping bearing 4 can be significantly
Degree improves front tyre and eats tire phenomenon.
Referring to Figures 1 and 2, hollow-out parts 12 are provided with front axle 1, hollow-out parts 12 are between multiple and axial direction along preceding bridge 100
It is arranged apart.By setting hollow-out parts 12 on front axle 1, rigidity, intensity and bearing requirements were not only met, but also realize front axle 100
Lightweight, and then the effect of vehicle energy-saving and emission-reduction.
As shown in Fig. 1, Fig. 5, Fig. 6 and Fig. 7, brake drum 221 is additionally provided with wheel hub 22, is provided with brake drum 221 anti-
Distressed structure 2211, anti-deforming structure 2211 is annular stirrup and cuff is on the outer circumferential surface of brake drum 221.Specifically, this reality
With new embodiment using steel loop brake drum 221,221 friction material of steel loop brake drum is gray iron, to overcome gray iron material
Thermal deformation resistant ability it is weaker the problem of increase stirrup structure, limitation brake drum 221 body ash on the outer circumferential surface of brake drum 221
The deformation of iron material, so as to ensure that vehicle has enough brake force, ensures traffic safety.
Further, as shown in Figure 1, anti-deforming structure 2211 is multiple and along the axially spaced arrangement of preceding bridge 100, wherein
The width of one anti-deforming structure 2211 is more than other anti-deforming structures 2211 and projecting height is less than other anti-deformation knots
Structure 2211.Thus, consolidation effect can be made more preferable, makes the non-deformability of brake drum 221 stronger.
Specifically, the anti-deforming structure 2211 of width maximum is arranged on the opposite exterior lateral sides of the outer circumferential surface of brake drum 221, other
Anti-deforming structure 2211 is arranged on the relative inner of the outer circumferential surface of brake drum 221.Certain the utility model embodiment is not limited only to
This, in another embodiment, as shown in Figure 5 and Figure 6, the anti-deforming structure 2211 of width maximum is arranged on the outer of brake drum 221
The relative inner of side face, other anti-deforming structures 2211 are arranged on the opposite exterior lateral sides of the outer circumferential surface of brake drum 221.
According to the vehicle of the utility model another aspect embodiment, including the preceding bridge 100 described in above-described embodiment.For
Other constructions of vehicle have been the prior art such as speed changer, braking system, steering and have been those skilled in the art
Known to member, therefore do not elaborate for other constructions of vehicle here.
