Abstract
The invention discloses a double arm independent suspension without a stabilizer bar, which comprises an upper triangular arm assembly of which one end is hinged with a wheel, and a lower triangular arm assembly of which one end which is hinged with the wheel, wherein the lower triangular arm assembly is connected with a spring shock absorber assembly, the vertex angle of the hinged joint betweenthe upper triangular arm assembly and the wheel is between 35 and 60 degrees, and the vertex angle of the hinged joint between the lower triangular arm assembly and the wheel is also between 35 and 60 degrees. Two connection points of the lower triangular arm assembly hinged with a frame are not in the same level plane, thereby the double arm independent suspension without the stabilizer bar is formed. The double arm independent suspension cancels the stabilizer bar which prevents the suspension spring from being deformed and reduces the transverse inclination and the transverse angular vibration of a vehicle, but does not change the driving performance of the whole vehicle, thereby achieving the aim of reducing component number of the suspension assemblies without changing other performances of the vehicle, simplifying the structure of the double arm independent suspension, and reducing cost.
Description
Technical field
The invention belongs to vehicle part, be specifically related to the independent suspension of a kind of pair of cross arm structure.
Background technology
After cross country car adopted independent suspension, just there was the phenomenon of suspension rate deficiency in double cross arm independent suspension particularly, when making motor turning, produces bigger angle of roll.For avoiding this phenomenon, improve the roll angular rigidity of suspension, add stabilizer antiroll bar (bar) in the suspension of being everlasting, guarantee the good riding stability of automobile.After adopting Panhard rod, when coaxial wheel sense of motion (go up and jump and jump down) was identical, stabilizer antiroll bar was inoperative; When coaxial wheel sense of motion (go up and jump and jump down) is inequality, vehicle body is with respect to the horizontal plane during lateral inclination, jump side direction vehicle body direction motion on the wheel, the homonymy of stabilizer rod is terminal just to move up with wheel, and wheel is jumped side down, and then wheel is to moving away from the vehicle body direction, and the terminal vehicle body relatively of respective transversal stabilizer rod moves down, the longitudinal component that causes the Panhard rod both sides makes that to different directions deflection Panhard rod is reversed.Elastomeric stabilizer rod produces and reverses the distortion that moment of resistance just hinders axle spring, has reduced the lateral inclination and the lateral angle vibration of automobile.Therefore double cross arm independent suspension comprises stabilizer antiroll bar.Now do not see the double cross arm independent suspension of not being with stabilizer antiroll bar as yet.
Summary of the invention
The object of the present invention is to provide a kind of double cross arm independent suspension that does not have Panhard rod, reduced the quantity of parts assemblies, save cost of development.
Technical scheme of the present invention is: the double cross arm independent suspension of no Panhard rod, it comprises the last triangle arm assembly that an end and wheel are articulated and connected, the following triangle arm assembly that one end and wheel are articulated and connected, connect the spring damper assembly on the following triangle arm assembly, the drift angle of last triangle arm assembly and wheel hinge-point is 40 °～50 °, and the drift angle of following triangle arm assembly and wheel hinge-point is 40 °～50 °; Two point of connection that following triangle arm assembly and vehicle frame are articulated and connected constitute the double cross arm independent suspension of no Panhard rod thus not in same horizontal surface.
In the following triangle arm assembly that coaxial both sides wheel is articulated and connected, two pairs of point of connection that the following triangle arm assembly of both sides and vehicle frame are articulated and connected are not in one side.
The present invention is by the drift angle of triangle arm assembly about increasing and wheel hinge-point, and essence is 10 °～20 ° spans that promptly strengthen time triangle arm assembly of drift angle that increase former triangle arm assembly down and wheel hinge-point.Two point of connection that triangle arm assembly and vehicle frame are articulated and connected under adopting are being articulated and connected in same horizontal surface not, the helical spring rigidity in the corresponding increase spring damper and the damping of bumper simultaneously, cancelled the distortion that hinders axle spring, reduce the lateral inclination of automobile and the Panhard rod of lateral angle vibration, but do not changed the rideability of car load; Thereby reach the target that reduces the suspension assembly composing quantity, but do not change other performance of automobile, simplify the structure of double cross arm independent suspension, cost-cutting.
Description of drawings
Fig. 1 does not have the double cross arm independent suspension scheme drawing of Panhard rod.
The specific embodiment
Present embodiment is used for the explanation to this claim; protection scope of the present invention is not limited to down the description of array structure, and those skilled in the art all is protection domains of the present utility model according to the indicative and indicative structure of doing that is different from present embodiment of the technical scheme that this claim proposes.
As shown in Figure 1, be articulated and connected on the wheel 1 and go up triangle arm assembly 2 and following triangle arm assembly 3; It is the A end that wheel 1 is articulated and connected and goes up triangle arm assembly 2, D end with following triangle arm assembly 3, connect spring damper assembly 4 on the following triangle arm assembly 3, at the mid point of following triangle arm assembly, promptly the point of connection of spring damper assembly and following triangle arm assembly is not on the mid point on the following triangle arm assembly length direction for the point of connection of following triangle arm assembly and spring damper assembly.In addition two point of connection F ends of following triangle arm assembly 3 and E hold and are articulated and connected on vehicle frame, and vehicle frame comprises and is linked to be single-piece subframe 5 and main car frame 6 in the present embodiment.Other two point of connection F of following triangle arm assembly 3 hold and the E end is articulated and connected at subframe 5.The B end and the C end of last triangle arm assembly 2 are articulated and connected on main car frame 6.The drift angle of last triangle arm assembly be 35 °～60 ° be angle BAC at 35 °～60 °, be in particular angle BAC at 40 °～50 °; The drift angle BAC that goes up the triangle arm assembly in the present embodiment is 47.42 °.The drift angle of following triangle arm assembly be 35 °～60 ° be angle FDE at 35 °～60 °, be in particular angle FDE at 40 °～50 °; The drift angle FDE that goes up the triangle arm assembly in the present embodiment is 44 °.Above-mentioned is preceding double cross arm independent suspension, and the last triangle arm assembly of middle back double cross arm independent suspension and the drift angle of wheel hinge-point are 45 °; The following triangle arm assembly of middle back double cross arm independent suspension and the drift angle of wheel hinge-point are 43.94 °.
The F end that following triangle arm assembly 4 and subframe 5 are articulated and connected and the point of connection of E end be not in same horizontal surface.The F end is lower than the E end in the present embodiment.In the following triangle arm assembly that coaxial both sides wheel is articulated and connected, two pairs of point of connection that the following triangle arm assembly of both sides and vehicle frame are articulated and connected (each two are articulated and connected a little promptly) are not in one side.Promptly the F of side end is lower than the E end among the figure, and the F ' end of opposite side is higher than E ' end.The following triangle arm assembly of certain both sides and two pairs of point of connection (each two are articulated and connected a little promptly) that vehicle frame is articulated and connected also can be in one sides.
