Abstract
The invention discloses an improved aluminum alloy wheel, which comprises a weight reducing nest on a wheel mounting surface, a casting groove at the side of a central hole, and two casting grooves at the outer side of a mounting surface. The casting weight reducing nest is arranged on the aluminum alloy wheel mounting surface, two casting grooves or a large through groove communicated with the weight reducing nest are/is formed at the outer side of the mounting surface, namely the two casting grooves at the outer side of the mounting surface are combined into a communicated large casting groove; and the position of the weight reducing nest close to the central hole is provided with the casting groove which is chamfered through the central hole and reaches a tool withdrawal groove of the central hole. The improved aluminum alloy wheel has the advantages of reducing the risk that a running system is eroded by accumulated water for a long term and improving the running reliability and safety.
Description
Technical field
The present invention relates to a kind of auto parts and components, relate in particular to a kind of rotatable parts of car chassis driving system.
Background technology
Aluminum-alloy wheel attachment face loss of weight nest is called drainage channel with the cast recess that the attachment face outside and centre hole side communicate.Its function is that the ponding of being invaded by Spindle nose cover place, wheel front in the vehicle traveling process is in time discharged, and prevents the parts corrosion, strengthens the safety of driving system.At present, general-duty aluminum-alloy wheel drainage channel is divided into following several form: one, wheel mounting surface loss of weight nest and the attachment face outside and centre hole side have no and communicate; Two, wheel mounting surface loss of weight nest has a cast recess to communicate with the attachment face outside, communicates with the centre hole chamfering, does not communicate with the centre hole relief groove; Three, wheel mounting surface loss of weight nest respectively has a cast recess to communicate with the attachment face outside and centre hole relief groove; Four, wheel mounting surface loss of weight nest has two cast recess to communicate with the attachment face outside, does not communicate with centre hole side; Five, wheel mounting surface loss of weight nest has two cast recess to communicate with the attachment face outside, communicates with the centre hole chamfering, does not communicate with the centre hole relief groove.
More than several general-duty structures have following problem: first kind, do not have drain function fully; Second kind, the centre hole side groove does not communicate with the centre hole relief groove, and ponding can't pass through centre hole Zhi Tai position; The third, ponding can be discharged through drainage channel, but the cast recess in this kind structure attachment face outside is arranged on the middle part of attachment face loss of weight nest outer side edges usually, and some remains in ponding in the attachment face loss of weight nest; The 4th kind, there is not drain function; The 5th kind, the centre hole side groove does not communicate with the centre hole relief groove, and ponding can't pass through centre hole straight section position.
Along with the raising of people to the vehicle product quality requirement; And country and enterprise are to the attention of traffic safety; Specific to aluminum-alloy wheel design and manufacturing; In order to prevent that ponding is penetrated between wheel hub and the axletree attachment face; Prevent its corrosion to the position parts that travel; Strengthen the reliability of running car system, be necessary the problems referred to above are solved.
Summary of the invention
In order to solve can't draining the water away of existing drainage channel structure existence; Perhaps ponding is got rid of not thorough; Cause ponding to be penetrated between wheel hub and the axletree attachment face; The position parts that travel are caused corrosion and then influence a series of problems such as reliability of running car system, and the present invention provides a kind of novel aluminum alloy wheel.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of aluminum-alloy wheel comprises wheel mounting surface loss of weight nest, centre hole side cast recess, two cast recess in the attachment face outside.Aluminum-alloy wheel attachment face position is provided with casting loss of weight nest; Two cast recess that communicate with the loss of weight nest of attachment face arranged outside or a big groove; Be about to two cast recess in the attachment face outside and merge into the big cast recess of a perforation, the loss of weight nest near the centre hole side setting through the centre hole chamfering and arrive the cast recess at centre hole relief groove position.
Said centre hole side cast recess is connected with attachment face loss of weight nest with the centre hole relief groove respectively, and two cast recess in the said attachment face outside are connected with attachment face loss of weight nest with the attachment face outside respectively.
The centre hole side cast recess is arranged on the midway location of attachment face loss of weight nest near the centre hole side, and the centre hole side cast recess connects centre hole chamfering, the straight platform of centre hole and centre hole relief groove.
Two cast recess in the wheel mounting surface outside are symmetricly set on the close outside two endpoint locations on one side of attachment face loss of weight nest.
In the vehicle traveling process; When the Spindle nose cover place intakes; Ponding gets into attachment face loss of weight nest through centre hole relief groove, centre hole straight section and centre hole chamfering place groove, and along with the rotation of wheel, ponding throws away through the cast recess in the attachment face outside under centrifugal action.Install because wheel is a symmetry, the setting of two cast recess in the attachment face outside can both be discharged the ponding that is assemblied in any single wheel on the automobile, does not exist ponding can't get rid of or get rid of halfway situation.
The invention has the beneficial effects as follows: adopt the centre hole side single casting to make groove, interior logical centre hole relief groove, the 1+2 structure of the double tank in the wheel mounting surface outside makes in the vehicle traveling process ponding thoroughly discharge the wheel set position.Reduce driving system and be subjected to the long-term risk that corrodes of ponding, improved travel reliability and safety.
Description of drawings
Fig. 1 is the improved aluminum-alloy wheel of a present invention back side schematic top plan view.
Fig. 2 is the improved aluminum-alloy wheel A-A of a present invention generalized section.
Among the figure: the 1-wheel mounting surface; 2-wheel mounting surface outside cast recess a; 3-wheel mounting surface outside cast recess b; 4-centre hole side cast recess; 5-wheel mounting surface loss of weight nest; 6-centre hole chamfering; The straight platform of 7-centre hole; 8-centre hole relief groove; 9-Spindle nose cover place.
The specific embodiment
In conjunction with the accompanying drawing and the specific embodiment the present invention is further specified.
Like Fig. 1, shown in 2; In the vehicle traveling process; Rainwater and surface gathered water can enter into aluminum-alloy wheel inside from Spindle nose cover 9, and through UNICOM's effect of centre hole side cast recess 4, ponding can enter into wheel mounting surface loss of weight nest 5 through centre hole relief groove 8 and the straight platform 7 of centre hole.In the process of wheel, for the wheel in automobile left side, ponding is discharged through attachment face outside cast recess 3 under action of centrifugal force; For the wheel on automobile right side, ponding is discharged through attachment face outboard row tank 2 under centrifugal action.
Effect through this kind 1+2 structure drainage channel; The assurance automobile can in time be discharged aluminum-alloy wheel in-to-in ponding in the process of moving; Just guaranteed that also aluminum-alloy wheel and automobile spindle nose position can not be in the environment of ponding corrosion for a long time, have strengthened the connection reliability and the safety at wheel set position.
