Abstract
The present utility model discloses a suspension guide mechanism applied for passenger car, freight car and various engineering vehicles, including a front vehicle bridge and two frame side rails. The utility model is characterized in that the front ends of the two frame side rails are provided with brackets whose two ends are fixedly connected with the two frame side rails respectively. A-shaped frame is disposed between the two ends of the two frame side rails and the front vehicle bridge. The front end of the A-shaped frame is articulated in the middle of the bracket and the rear ends of two oblique arms thereof are projected at the lateral sides of the two frame side rails with a gentle rotation angle radius and are fixedly connected with the front vehicle bridge. Crossbars are disposed between the A-shaped frame and the frame side rail, one end of the crossbar is articulated near the rear end of one oblique arm of the A-shaped frame and the other end is articulated on the corresponding frame side rail. The suspension guide mechanism can be applied for normal passenger, freight vehicles and also for engineering vehicles, especially for construction machinery with a wide application scope.
Description
(1) technical field
The utility model relates to a kind of guiding mechanism of hydro pneumatic suspension, is applicable on passenger vehicle, lorry and the various engineering truck.
(2) background technology
Guiding mechanism is the chief component of suspension, is important Force transmission parts, is bearing the task that wheel is beated with respect to vehicle frame and vehicle body according to certain track again, can also guarantee the appropriate location of tire.Dissimilar suspensions is furnished with multi-form guiding mechanism.In hydro pneumatic suspension, guiding mechanism commonly used is the four link type guiding mechanism.This guiding mechanism contains two longitudinal rods and two oblique propelling rods, and an end of two longitudinal rods is hinged on two chassis side rail inboards respectively, and their other end and preceding vehicle bridge are hinged, and they are paralleled with two chassis side raiies.One end of two oblique propelling rods also is hinged on two chassis side rail inboards, and their other end and preceding vehicle bridge are hinged, and makes between they and two chassis side raiies and form certain included angle.When the suspension oil cylinder produced elastic displacement under vehicle running state, two longitudinal rods and two oblique propelling rods carried out reciprocally swinging around its hinge-point on chassis side rail respectively.Owing to be subjected to the influence of propelling rod length and spatial destribution, make the trim rigidity and the roll rate of whole suspension be restricted.Therefore, this guiding mechanism is only applicable on the trim of suspension and the less demanding common visitor of roll rate, the goods vehicle.For engineering truck, especially construction machinery and equipment, its weight is big, barycenter is higher, and used chassis side rail and common visitor, goods vehicle are different, and also more complicated of the road conditions that it travelled.For guaranteeing that engineering truck has excellent traveling stability, have bigger trim rigidity and roll rate with regard to requiring used suspension.If suspension trim insufficient rigidity, during car brakeing easy " nodding ", easy during acceleration " squatting in the back ".If the roll rate deficiency of suspension, just greatly, severe turbulence can appear in the lighter in inclination during Vehicular turn, and weight person can cause roll-over accident.Therefore, the four link type guiding mechanism only is applicable on common visitor, the goods vehicle, and is not suitable on the engineering truck, and Applicable scope is wideless.
(3) summary of the invention
The purpose of this utility model is to provide a kind of suspension guide mechanism.This suspension guide mechanism can be used on common visitor, the goods vehicle, can be used on engineering truck, the especially construction machinery and equipment again, and Applicable scope is wider.
Above-mentioned purpose of the present utility model is realized by following technical solution:
Suspension guide mechanism of the present utility model, vehicle bridge and two chassis side raiies before comprising.Its constructional feature is that two chassis side rail front ends have support, and the two ends of this support are connected mutually with two chassis side raiies respectively, between itself and the preceding vehicle bridge A shape frame is arranged.The front end of this A shape frame is hinged on the centre of support, and give prominence in the two chassis side raiies outside with mild knuckle radius its two oblique arms rear end, and is connected mutually with preceding vehicle bridge.Between A shape frame and chassis side rail intermediate rod is arranged, an end of this intermediate rod is hinged on the rear end of leaning on of an oblique arm of A shape frame, and the other end then is hinged on the corresponding chassis side rail.
Take such scheme, have the following advantages:
Because give prominence in the two chassis side raiies outsides with mild knuckle radius at A shape frame rear portion, and be connected mutually with preceding vehicle bridge, make that the distance between the stress point of suspension both sides increases, thereby improved the roll rate of whole suspension.
Because car longeron front end has support, and A shape frame front end is hinged on this support, on the vehicle bridge, make that the length of A shape frame two oblique arms is long, the vertical equity angle is smooth before its rear end is fixed in again, effectively improved the longitudinal rigidity of suspension.
In addition, because two oblique arms of A shape frame are to be welded by steel plate, and their cross-sectional plane becomes big gradually from front end to the rear end.Both can make the suffered distribution of stress of A shape frame even, can reduce its size and weight again, also reduce cost simultaneously.
(4) description of drawings
Fig. 1 is a suspension guide mechanism scheme drawing of the present utility model;
Fig. 2 is the schematic top plan view of Fig. 1 of oil-containing cylinder not.
(5) specific embodiment
As shown in Figure 1 and Figure 2, suspension guide mechanism of the present utility model, vehicle bridge 8 and two chassis side rail 10, two chassis side raiies 10 is provided with support 3 foremost before containing.This support is horizontally set, and its two ends are welded on the front end end of two chassis side raiies 10 respectively.Be provided with A shape frame 9 between said support 3 and the preceding vehicle bridge 8, this A shape frame contains two oblique arms, an end weld together of two oblique arms, thereby the front end of formation A shape frame 9.The front end of A shape frame 9 is processed with axis hole, and the centre of support 3 also is processed with axis hole accordingly.A shape frame 9 front ends are hinged on the centre of support 3 by oscillating bearing 2, axle 1 and these axis holes.Give prominence in two chassis side raiies, 10 outsides with mild knuckle radius two oblique arm rear ends of A shape frame 9.Two oblique arms of A shape frame 9 all are to be welded by four block length strip steel plates, and their cross section becomes big gradually from its front end to the rear end.Wherein, outside upper and lower two block plates of two oblique arms are given prominence in its back-end, so that form horizontal draw-in groove in two oblique arm rear ends.The draw-in groove of said two oblique arm rear ends all is stuck on the preceding vehicle bridge 8, and fixes with bolt 7.Under confined state, two oblique arm rear ends of A shape frame 9 respectively are provided with an oil gas cylinder 5, and the upper end of this two oil gas cylinder is hinged on respectively on two chassis side raiies 10, and the lower end then is connected with the lower ear base 6 of 9 liang of oblique arm rear ends of A shape frame respectively.10 parts of A shape frame 9 and chassis side rail are provided with intermediate rod 4, an end of this intermediate rod be hinged on 9 one oblique arms of A shape frame by rear end, the other end then is hinged on the chassis side rail 10 on another oblique arm.
