Background technology
Rear suspension is mainly based on the semi-independent suspension of torsion beam, and its main advantage is with low cost, but because its suspension performance has determined its car load not have high-caliber handling and traveling comfort.Therefore, some domestic independent brand begins to be equipped with four connecting-rod separated suspensions at present, obtaining handling preferably and traveling comfort, and the design of part complexity such as bigger, carriage, trailing arm but it takes up room, and cost is higher, has limited the widespread use of this kind suspension.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, compact Independent Suspension device, to address the above problem.
The technical solution of the utility model is: the Independent Suspension device, and it comprises longeron, and longeron is that tubing bends and forms, and an end of longeron is welded to connect sleeve pipe, connects lining on the sleeve pipe; The back segment of longeron is welded to connect: first support that is used for the connection hub-bearing unit; Second support that is used for the connection Top Crossbeam, the side plate of second support and first support constitutes " U " shape; The 3rd support that is used for the connection lower cross arm; Also be provided with first bearing pin that is used for the connection shock absorber on the longeron, be used for second bearing pin of connection stabilizer rod hanger; The Top Crossbeam and second support are articulated and connected, and lower cross arm and the 3rd support are articulated and connected, and spring is located on the lower cross arm; Shock absorber is connected with first bearing pin, and stabilizer rod is connected with second bearing pin.
Described Top Crossbeam, shock absorber, lower cross arm front and back are successively arranged; Lower cross arm is longer than Top Crossbeam.
Transverse arm is a forging, and lower cross arm is towards weldment;
The utility model is a kind of simple in structure, compact, with low cost, and can have independent suspension frame unit good handling and traveling comfort.

The prenex scheme drawing that forms when Fig. 4 is subjected to side force;
The specific embodiment
This independent suspension frame unit is the left-right symmetric structure, for the purpose of illustrative simplicity, has only shown the scheme drawing of its left side structure.
As shown in Figure 1, this independent longeron 1, lower cross arm 2, Top Crossbeam 3, shock absorber 4, spring 5, stabilizer rod 6, stabilizer rod hanger 7.
Trailing arm 1 is formed by the tubing 1a bending of circular section.Shown in Fig. 2,3, its front end is welded with a sleeve pipe 1b, press-fits lining 1h therebetween, is connected on the vehicle body by lining 1h is elastomeric.Back segment at trailing arm 1 is welded with three supports, is respectively:
Support 1e is a U template, is welded in the back segment of trailing arm pipe 1a, and design is used to install lower cross arm 2 to clearance hole.
Similarly, pivot pin 1g is used to install the lining of stabilizer rod hanger upper end.
Return Fig. 1.Lower cross arm 2 is the punching press weldment, and the outer end is by on lining connection and the trailing arm support 1e, and the inner is connected with carriage by lining equally.
Similarly, Top Crossbeam 3 is a forging, and two ends press-fit lining; One end is connected with carriage, in the U type space that the support 1c of other end insertion trailing arm 1 and 1d form, installs by overbolt.
Shock absorber 4 separates parallel the layout with spring 5.Spring 5 is installed between the spring tray and carriage spring tray of lower cross arm 2, and each design of two ends has the shock pad (not shown) up and down, to reduce noise transfer.And this mounting means makes the structure of suspension more compact, the rear suspension modularization packing when helping entrucking.
Shock absorber 7 is arranged between Top Crossbeam 3 and the lower cross arm 2, and the upper end is connected in vehicle body by elastic support; The lower end is a tube-in-tube structure, press-fits lining, is inserted on the pivot pin 1f of trailing arm 1, fixes with nut.
Stabilizer rod 6 is fixed on the tail-bracket bottom by the fixed bearing (not shown) of elastomeric material, hangs on trailing arm by stabilizer rod hanger 7; Stabilizer rod hanger 7 lower ends connect stabilizer rod, are the ball latch structure; The upper end connects trailing arm, is bush structure, is inserted on the pivot pin 1g of trailing arm 1, fixes with nut.
Numerous parts have from the above mentioned constituted the independent suspension frame unit of this example.
In this example, preferably:
From the car load vertical direction, trailing arm lining 1h's is axial roughly towards the point of connection direction of lower cross arm 2 with tail-bracket, and in the motion process, suspension swings up and down around this axis; The swing of Top Crossbeam simultaneously guarantees that then the camber angle of suspension on the go satisfies Changing Pattern preferably.
See at the car load vertical direction, lower cross arm 2 and trailing arm 1 point of connection, more forward than itself and carriage point of connection.With regard to car load laterally, Top Crossbeam 3 lining rigidity are less than lower cross arm 2 linings.The hinged rigidity of trailing arm is less relatively, thereby makes the vibration that is delivered to vehicle body as much as possible little; And its radial rigidity is greater than axial stiffness.
This design-calculated advantage is:
As shown in Figure 4, see at the car load vertical direction; When the car load turning was subjected to side force, side force was delivered on transverse arm and the trailing arm by trailing arm support 1c.As mentioned above, trailing arm lining 1h rigidity minimum, thereby deflection maximum, and inwardly, backward the distortion; And lower cross arm 2 lining rigidity maximums, thereby deflection minimum to the inside, and produce backward small sway; Thereby make wheel produce a positive toe-in, cause the understeer of vehicle, improved steering stability.
Similarly, in car load braking, wheel be subjected to that ground provides along car load braking force backward, 1c is delivered on trailing arm and the transverse arm by the trailing arm support.Similarly, the hinged 1h of trailing arm produce less inwardly, bigger deformation moving distance.At this moment, two transverse arms are then around correspondingly swinging backward with the point of connection of carriage separately.Above-mentioned lower cross arm 2 is the longest, and itself and trailing arm 1 point of connection are forward with the carriage point of connection, so the bigger outside deflection of this some generation; Make wheel produce a positive toe-in, improved the stability of glancing impact.
And in this example, prenex control apparatus is: the aperture that the front end lining 1h of trailing arm 1 and vehicle body are installed is greater than the external diameter of hold-down bolt; This design can be easily laterally, the position of hinge-point before the fore-and-aft adjustment trailing arm, fine setting is prenex, the purpose of wheelbase thereby reach.
By above-mentioned introduction as can be seen, this draft hitch is simple in structure, compact, be easy to arrange, has increased free space, especially trailing arm simple in structure, with low cost of baggage container, fuel tank, has better economic; This suspension has handling preferably and traveling comfort simultaneously, has improved the NVH performance of vehicle simultaneously.
