Abstract
The invention provides a two-hinge guide automobile suspension mechanism capable of turning in a crab walk manner. The two-hinge guide automobile suspension mechanism aims to design an automobile suspension which can achieve four-wheel independent drive and independent turning of an automobile for the automobile. More importantly, by means of the suspension mechanism, the automobile can turn by 90 degrees. In addition, the automobile can directly turn in situ. The automobile suspension mechanism mainly comprises suspension supporting arms and suspension guide mechanisms. The upper ends of the supporting arms are connected with hub motor shafts through side flanges respectively. The lower ends of the supporting arms are connected with the two ends of the suspension through suspension lower flanges respectively. Each suspension guide mechanism comprises two hinge mechanisms. If the two-hinge guide automobile suspension mechanism is arranged on the whole automobile, the two-hinge guide automobile suspension mechanism can be arranged on the whole automobile by only connecting suspension upper flanges with extending couplers of a steering motor. By means of the two-hinge guide automobile suspension mechanism, 90-degree turning can be achieved, and the automobile can directly turn in situ. The suspension mechanism has the beneficial effects that the independent turning angle range of wheels is wide, assembly is convenient, and the cost is low.
Description
Technical field
The invention belongs to field of automobile suspension, especially with realizing 90 ° of automotive suspensions freely turned to.
Background technology
Along with the development of China's economic, automobile more and more becomes the indispensable part in compatriots' life.Meanwhile, along with day by day increasing of city vehicle, the traffic in city is also faced with immense pressure.In the city of an inch of land is an inch of gold, the space of parking of stopping is subject to great restriction, and the phenomenon that parking stall is more expensive than car even appears in some city.If automobile can berth and can drive into and roll away from less parking stall, a part of space can be saved like this.So the alerting ability of automobile also becomes more and more important, and 90 ° of automobiles turned to just and can allow during car a lot of convenience is provided at automobile warehouse-in.And automobile can be turn-taked in original place, reduce motor turning radius, and this automobile can directly in original place 180 ° turn around to turn to.Design so a kind of automotive suspension mechanism, to meet the demand of modern society people to automobile function.
Summary of the invention
The invention provides a kind of automotive suspension mechanism that can realize the two hinge guiding that crab row turns to.This suspension fork mechanism can realize 90 °, automobile and directly turn to, and original place such as directly to turn at the advantage.
Technical scheme of the present invention is: a kind of suspension fork mechanism that can realize the two hinge guiding that crab row turns to.This mechanism mainly comprises suspension support arms and suspension guide mechanism.The two ends of hold-down arm are connected with suspension two ends with wheel hub motor axle with suspension lower flange respectively by side flange, and have two sleeves between the upper lower flange of suspension, springs sit is inside sleeve, and shock absorber is enclosed within spring inner.This guiding mechanism includes two groups of linkages, often organizes linkage and all comprises epipleurite, hypopleurite, hinged-support, rotational pin and copper sheathing five part.By two groups of linkages by together with the upper and lower Flange joint of bolt and suspension.During to be installed to car load, only the coupler that suspension upper flange and steer motor are stretched out need be connected.The present invention can realize 90 °, automobile and turn to.
Described suspension support arms, the transverse arm weld together of its suspension lower flange and hold-down arm, ensures its intensity by two main ribs.Weld the strengthening rib of in the angle of two hold-down arms, improve its integral rigidity.Equally, for connect wheel hub motor shaft side flange be also be connected with vertical arm by welding manner, its dorsal part then ensures its strength and stiffness by four main ribs and two auxiliary ribs.
Described suspension guide mechanism, this guiding mechanism includes two groups of linkages, often organizes linkage and all comprises epipleurite, hypopleurite, hinged-support, rotational pin and copper sheathing five part, its principle of work is epipleurite, hypopleurite, two hinged-supports are connected with six copper sheathings by three rotational pins.Wherein, the upper end of rotational pin and hinged-support and hypopleurite is interference fit, all copper sheathing is installed in epipleurite two stomidium and in the hole of hypopleurite lower end, it is also interference fit between them, copper sheathing and and rotational pin between be then the very little free-running fit in gap, therefore can rotate between copper sheathing and rotational pin.When three groups of such linkages to be distributed on suspension between lower flange as indicated in the figure, relative motion relation between two flanges will be limited, namely between two flanges only with catenary motion, like this when they are as guiding mechanism, the various force and moments except vertical power will be transmitted.
The present invention has following effect: turning to automobile, can realize 90 °, automobile and turn to.And automobile in-place can be realized turn-take, reduce automobile turning radius, automobile can directly in original place 180 ° turn around to turn to.

Detailed description of the invention
In order to understand technical characterstic of the present invention better, below in conjunction with accompanying drawing, the present invention is further described.
The invention provides and a kind ofly can realize 90 ° of automotive suspension mechanisms turned to.As in Fig. 1: in the suspension support arms of this automotive suspension mechanism, transverse arm 4 weld together of suspension lower flange 8 and hold-down arm, ensure its intensity by two main ribs 6, the interface of transverse arm and vertical arm respectively cuts otch at 45 °.In addition, welded the strengthening rib 5 of in two-arm angle, improved its integral rigidity.Equally, be also be connected with vertical arm 2 by welding manner for connecting the side flange 1 of wheel hub motor shaft, its dorsal part ensures its strength and stiffness by four main ribs 6 and two auxiliary ribs 7.Finally, the two ends of hold-down arm are connected with suspension two ends with wheel hub motor axle with suspension lower flange 8 respectively by side flange 1.
As in Fig. 2, in this guiding mechanism, include two groups of linkages, often organize linkage and all comprise epipleurite 13, hypopleurite 10, hinged-support 9, rotational pin 12 and copper sheathing 11 5 part.Two groups of linkages are linked together by bolt 18 and lower flange 14 and 8 on suspension.The upper flange 14 of hold-down arm has a sleeve 15, and spring 16 is placed in the inner side of sleeve 15, and shock absorber 17 is enclosed within the inside of spring 16.During to be installed to car load, only the coupler that suspension upper flange 14 and steer motor are stretched out need be connected.Its principle of work is epipleurite 13, hypopleurite 10, two hinged-supports 9 are connected with six copper sheathings 11 by three rotational pins 12, wherein, the upper end interference fit of rotational pin 12 and hinged-support 9 and hypopleurite 10, in epipleurite 13 liang of stomidiums and in the hole of hypopleurite 10 lower end, copper sheathing 11 is all installed, it is also interference fit between them, copper sheathing 11 and and rotational pin 12 between be then the very little free-running fit in gap, therefore can rotate between copper sheathing and rotational pin.When two groups of such linkages are distributed between upper and lower two flanges of suspension as indicated in the figure, relative motion relation between two flanges will be limited, namely between two flanges only with catenary motion, like this when they are as guiding mechanism, the various force and moments except vertical power will be transmitted.
The present invention is applied to the automobile of four-wheel steering.This automotive suspension mechanism module that four identical can be adopted.
