The utility model relates to a car suspension, in particular to a MacPherson-type air suspension, comprising a shock absorber, a sliding bearing, a combined air spring, standard thread bolts and nuts,a support plate and an upper point cover plate. The car suspension is characterized in that the combined air spring comprises an air spring retainer, combined thread bolts, a novel air spring, an auxiliary mechanism, a shroud ring and a steel ball, wherein the novel air spring, the air spring retainer and the upper point cover plate are connected by the combined thread bolts, the sliding bearingfits to the shock absorber in an interference way, the air spring retainer is directly contacted with the sliding bearing, the inner side of the novel air spring directly clings to the auxiliary mechanism, the shroud ring and the steel ball are embedded on the inner side of the auxiliary mechanism, and the steel ball is embedded in the shroud ring. The MacPherson-type air suspension combines structural compactness and good operational stability of a MacPherson-type suspension and excellent smoothness and comfort level of an air suspension, thereby exploring the advantages of the two suspensions.
Description
Technical field
The utility model relates to a kind of vehicle suspension, refers in particular to the MacPherson type air suspension.
Background technology
Current McPherson strut is popularized in car very much, is MacPherson strut as the front suspension of cars such as homemade Audi, Santana, Xiali, Citroen zx.The advantage of tradition McPherson strut is: compact conformation, Front wheel Alignment Parameters changes for a short time during wheel bounce, and good road-holding property is arranged, and adds owing to cancelled Top Crossbeam, brings convenience to the layout of driving engine and steering swivel system.Air suspension is used also more universal, and its major advantage is: the ride comfort and the travelling comfort that improve vehicle.Yet traditional air suspension takes up room greatly, is mainly used in luxury car at present.How with the advantage combination of these two kinds of suspensions, both can the implementation structure compactness, good road-holding property is arranged, the vehicle ride comfort that can realize ideal and travelling comfort have just very had realistic meaning again.
Summary of the invention
Technical problem to be solved in the utility model is: with the structural compactness and the outstanding ride comfort combination of air suspension of McPherson strut, save the guiding mechanism of conventional air suspension, the advantage of two kinds of suspensions is all brought into play.
The utility model solve this technical problem adopted technical scheme be: this MacPherson type air suspension, by bumper, plain bearing, the combination air bellow, regular bolt and nut, support plate and last fulcrum cover plate are formed, it is characterized in that making up air bellow and comprise the air bellow retainer, assembling bolt, novel air spring, auxiliary mechanism, garter spring and steel ball, novel air spring, air bellow retainer and last fulcrum cover plate link together by assembling bolt, plain bearing and bumper interference fit, air bellow retainer and plain bearing direct contact, the novel air spring inboard directly is attached in the auxiliary mechanism, the auxiliary mechanism inboard is embedded with garter spring and steel ball, steel ball is embedded in the garter spring, combine, the steel ball direct contact is in the outer wall of air bellow retainer, the novel air spring lower end also is embedded with garter spring and steel ball simultaneously, the steel ball direct contact is in the outer wall of air bellow retainer, and novel air spring base and support plate link together by regular bolt and nut.The combination air bellow has had the picture coil spring and has transmitted the function of longitudinal force and side force aspect, thereby can replace coil spring.Novel air spring is the conventional air spring to be done circularize, and novel air spring comprises novel diaphragm type air spring and novel bellows type air spring simultaneously, and structural representation is the example explanation with novel diaphragm type air spring.Novel air spring is when compression or stretching, the air bag inside and outside wall all will be out of shape, the gasbag ektexine distortion is not restricted, yet the air bag inwall inwardly applies power under very big gaseous tension, and inwall inwardly swells simultaneously, has strengthened the friction between novel air spring and the air bellow retainer, when to lower compression, disadvantageous aspects such as being superimposed also can appear in inwall, when utilizing auxiliary mechanism to move up and down with regard to well having solved air bellow, the problem that friction drag is big and inwall superposes.
The utlity model has following outstanding advantage:
1, the combination air bellow had both had variable rigidity, had the function of transmitting longitudinal force and side force again.
2, combination air bellow and bumper are used, and have saved the guiding mechanism of conventional air suspension, make the structure of suspension compact more.
3, after other parts of the air bellow of the utility model replacement conventional air suspension and guiding mechanism and conventional air suspension system are combined, both had the advantage of McPherson strut, had the advantage of air suspension again.

As shown in the figure, number in the figure is represented respectively: 1, bumper 2, plain bearing 3, air bellow retainer 4, assembling bolt 5, novel air spring 6, novel air spring outer wall 7, novel air spring inwall 8, auxiliary mechanism 9, garter spring and steel ball 10, regular bolt and nut 11, support plate 12, last fulcrum cover plate
The specific embodiment
Describe the utility model embodiment in detail below in conjunction with accompanying drawing
Consult Fig. 1, novel air spring 5, air bellow retainer 3 and last fulcrum cover plate 12 link together by assembling bolt 4, and assembling bolt 4 is connected on the vehicle body.Plain bearing 2 and bumper 1 interference fit, air bellow retainer 3 and plain bearing 2 direct contacts, novel air spring 5 inboards directly are attached in the auxiliary mechanism 8, auxiliary mechanism 8 inboards are embedded with garter spring and steel ball 9, steel ball is embedded in the garter spring, combine, the steel ball direct contact is in the outer wall of air bellow retainer 3, novel air spring 5 lower ends also are embedded with garter spring and steel ball 9 simultaneously, the steel ball direct contact is in the outer wall of air bellow retainer 3, and novel air spring 5 bases and support plate 11 link together by regular bolt and nut 10.
Consult Fig. 2, air bellow retainer 3 is connected by assembling bolt 4 with novel air spring 5, novel air spring 5 inboards directly are attached in the auxiliary mechanism 8, auxiliary mechanism 8 inboards are embedded with garter spring and steel ball 9, steel ball is embedded in the garter spring, combine, the steel ball direct contact is in the outer wall of air bellow retainer 3, novel air spring 5 lower ends also are embedded with garter spring and steel ball 9 simultaneously, the steel ball direct contact is in the outer wall of air bellow retainer 3, combine in this way, become one and independently make up air bellow.
Consult Fig. 3, auxiliary mechanism 8 inboards are embedded with garter spring and steel ball 9, and steel ball is embedded in the garter spring, combines.
Each mechanism's working process specifies as follows: when vehicle body vibrates downwards, last fulcrum cover plate 12 moves downward, bumper 1 top moves downward, vehicle body is subjected to the dumping force of bumper 1, air bellow retainer 3 moves downward along plain bearing 2 simultaneously, novel air spring 5 is pressed, vehicle body is subjected to the elastic force that novel air spring 5 makes progress, the air bag internal gas pressure increases, novel air spring inwall 7 is pressed, inside protuberance, auxiliary mechanism 8 relies on garter spring that inner ring surface is embedded with and steel ball 9 along with novel air spring inwall 7 moves downward on the one hand, can eliminate novel air spring inwall 7 inwardly protuberance and stack on the other hand.Bumper 1 and novel air spring 5 move downward air bellow retainer 3 relatively simultaneously.Each motion of mechanism process as mentioned above.When the vehicle body upward movement, each mechanism kinematic and above-mentioned similar, just sense of motion is opposite.So just the motion feature of traditional McPherson strut motion feature and conventional air suspension has all been realized, thus the conventional air suspension of having brought into play and the advantage of traditional McPherson strut, the effect of realizing ideal.
