Description
Technical Field
The utility model relates to the technical field of automobile accessories, in particular to a novel rear multi-connecting-rod support splash-proof structure.
Background
Since the days when automobiles are put into practical use, people have never stopped their pursuits for control and comfort, and the design of suspension, steering and other systems almost determines the level of vehicle operation. The more complex the suspension form of passenger cars, from simple macpherson/torsion beams to three-link, four-link, five-link suspensions, etc. Conventionally, suspensions of four or more link configurations are commonly referred to as multi-link suspensions. The multi-link suspension has more links than a common suspension, can provide control force in multiple directions, enables wheels and the ground to be kept vertical as much as possible, reduces the inclination of a vehicle body as much as possible, maintains the ground-contact performance of the tire as much as possible, enables the tire to have a more reliable running track, and can ensure that the vehicle has good comfort.
The multi-link suspension can be divided into a multi-link front suspension and a multi-link rear suspension, and is applied to a front wheel and a rear wheel of an automobile respectively. The rear multi-link bracket (also called rear steering knuckle) is a component of a multi-link rear suspension and is mainly used for connecting each control arm, a hub bearing and a control caliper of the multi-link rear suspension and bearing the load transmitted by a wheel. The splash-proof structure of the conventional rear multi-link support 2 is as shown in fig. 1 and fig. 2, and a buckle 4 is pressed on the back side plane of the rear multi-link support 2, so that when a driving shaft 3 drives a wheel to rotate, muddy water is prevented from splashing to an induction surface of a hub unit 1, ABS reading instability is prevented, or muddy water is immersed in the hub unit 1 to influence a transmission function, and even abnormal sound is generated. The conventional technical scheme has the following defects: (1) the buckle needs to be pressed on the rear multi-connecting-rod support 2, the falling risk exists, and the abnormal sound generated after falling is more serious; (2) the buckle is the injection molding, has worn and torn, has the splash risk after long-term the use.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects in the prior art and provide the improvement of the rear multi-link bracket splash-proof structure, and the improved splash-proof structure can reduce the cost, improve the price advantage of an assembly, reduce the assembly procedures, shorten the assembly time and reduce the neglected assembly risk.
The technical scheme adopted by the utility model is as follows:
the utility model provides a novel back multi-link support splashproof mud structure, sets up between back multi-link support and drive shaft, includes the little step of at least one circled, and this little step extends one section distance from the drive shaft mounting hole inner wall of back multi-link support towards the drive shaft, the outer lane of little step and back multi-link support integrated into one piece, the outer wall clearance fit of inner circle and drive shaft.
In a further scheme, the rear multi-link support is provided with a drainage groove for discharging muddy water, and the drainage groove is located at the lowest position of the driving shaft mounting hole.
In a further aspect, the drain channel gradually decreases in height from one end of the drive shaft mounting hole near the hub unit to the other end, forming a slope that accelerates discharge of muddy water.
In a further scheme, an included angle between the slope and the horizontal plane is 15-60 degrees.
The utility model has the beneficial effects that: (1) the small steps integrally formed with the rear multi-connecting-rod support are adopted to block muddy water, so that the falling risk is avoided, and abnormal sound caused by falling of the buckles is avoided; (2) the buckle is eliminated, the production cost is reduced, and the price advantage of the assembly can be improved; (3) an assembly procedure is reduced, the assembly time of the assembly is shortened, and the risk of neglected mounting of the buckle is reduced; (4) the drainage channel structure is added, so that the abrasion and the corrosion caused by long-time accumulation of muddy water among the rear multi-link support, the hub and the driving shaft are prevented.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples, but the present invention is not limited to the following examples, so that the objects, solutions and advantages of the present invention can be more clearly understood by those skilled in the art.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified and limited, specific meanings of the general terms in the present invention may be specifically understood by those skilled in the art.
As shown in fig. 3 and 4, the novel rear multi-link bracket 2 splash-proof structure provided by the utility model is arranged between the rear multi-link bracket 2 and the driving shaft 3, and replaces the position of the buckle 4 of the existing splash-proof structure, and comprises at least one small step 21 extending into a ring shape along the inner wall of the driving shaft mounting hole 5, when one small step 21 is arranged, the small step 21 is positioned at the back plane of the rear multi-link bracket 2, and when two or more small steps 21 are arranged, the small steps 21 are arranged at a certain distance along the axial direction of the driving shaft mounting hole 5. Each small step extends for a distance from the inner wall of a driving shaft mounting hole 5 of the rear multi-link support 2 to the driving shaft 3, the outer ring of the small step is integrally formed with the rear multi-link support 2, and the inner ring of the small step is in clearance fit with the outer wall of the driving shaft 3.
In order to discharge the muddy water quickly and avoid the wear and the corrosion caused by the muddy water being accumulated among the rear multi-link bracket, the hub and the driving shaft for a long time, the rear multi-link bracket 2 is provided with a drainage groove 22 for discharging the muddy water, and the drainage groove 22 is positioned at the lowest part of the driving shaft mounting hole 5 to assist the discharge of the muddy water. As shown in fig. 3 and 4, the drain groove 22 gradually decreases in height from one end (end a in fig. 3) of the drive shaft mounting hole 5 near the hub unit 1 to the other end (end B in fig. 3), forming a slope 23 that accelerates discharge of muddy water. The included angle between the slope 23 and the horizontal plane can be determined according to requirements, and is preferably 15-60 degrees, and is preferably 25 degrees.
When the whole vehicle is running, most of muddy water cannot enter the inner space through the narrow gap between the small step 21 and the drive shaft 3. Considering the weight factor, the muddy water flows downstream from the drainage groove 22 to the lowest point of the finished vehicle and flows out of the inner space through the slope 23, so that the problem of the damaged performance of the finished vehicle caused by the muddy water existing in the inner space and further invading the hub unit is greatly reduced.
The above description is only a preferred embodiment of the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
