Description of reference numerals
The specific embodiment
Incorporated by reference to consulting Fig. 1-2, rear suspension of cross-country vehicle of the present utility model comprises: the shock-absorption device 10 that is located at respectively vehicle bridge 2 two ends; Be arranged on the lateral rod 12 on described cross member of frame 30, for guaranteeing the relative position of vehicle bridge 2 and vehicle frame 3, prevent that both from teeter occurring; The stabilizer rod upper bracket 14 that is connected with described shock-absorption device 10 respectively and arranges perpendicular to vehicle bridge; Be connected to two Panhard rods 16 between described stabilizer rod upper bracket 14, for uneven road surface, for balance left and right wheels, improve driving stability; One end is connected with the end of described vehicle bridge 2, the oblique angle propelling rod 18 that the other end is connected with drive-shaft tunnel 4.
Described shock-absorption device 10 comprises: support 100, and this support 100 comprises upper bracket 1000 and lower bracket 1002; Coil spring 102, the top of this coil spring 102 is fixedly connected with described upper bracket 1000, and bottom is fixedly connected with described lower bracket 1002; And bumper 104, this bumper 104 is fixedly connected with upper bracket 1000, for suppressing coil spring 102 crank motions.
Described coil spring 102 preferably adopts 60Si2CrVa spring steel, through shot-ball peening, improves its intensity, and hardness reaches 45-52HRC; The rotation direction that it will be understood by those skilled in the art that described coil spring 102 is preferably left-handed and dextrorotation and is combined with, and in left wheel one side, left-handed spring is installed, and in right wheel one side, dextrorotation spring is installed.
The upper bracket 1000 of described shock-absorption device 10 is with coil spring 102 for integral type designs, and lower bracket 1002 is fixedly connected with vehicle bridge 2.Resistance to compression pression 2000N ± the 240N of described shock-absorption device 10, recovery resistance is 8000N ± 960N.
Described lateral rod 12, one end is loaded on vehicle bridge 2, and the other end is loaded on the cross member of frame 30 of vehicle frame 3, can guarantee vehicle bridge 2 and vehicle frame 3 relative positions, prevents that both from teeter occurring each other.
Described stabilizer rod upper bracket 14, is connected to vehicle bridge 2 by shock-absorption device 10 and described lateral rod 12, vehicle bridge 2 by described stabilizer rod upper bracket 14 carry-over moments to lateral rod 12.When left and right wheels overbalance, by the twisting of Panhard rod 16 and the rotation of stabilizer rod upper bracket 14 and vehicle frame 3 junctions, realize the lateral stability of balance rear-pendant.
Panhard rod 16, the spring steel that preferred material is 50CrVA, heat treatment hardness is 39-45HRC.Described Panhard rod 16 is mainly used in tackling uneven road surface, for balance left and right wheels, improves driving stability performance; Coordinate coil spring 102 and bumper 104 simultaneously, jointly improve ride comfort.
Incorporated by reference to consulting Fig. 3-4, described oblique angle propelling rod 18, one end is installed on vehicle bridge 2, and the other end is installed on drive-shaft tunnel 4.The mounting means using in prior art is normally installed on vehicle bridge 2 by propelling rod 18 one end, described oblique angle, and the other end is installed on vehicle frame 3.Compare with this mounting means of prior art, the utility model first in the outer setting of propeller-shaft 5 drive-shaft tunnel 4, then a section of being originally arranged on vehicle frame 3 has been transferred on drive-shaft tunnel 4.The connection mode of the oblique angle propelling rod 18 that the utility model adopts is larger than the antitorque amplitude of connection mode being directly installed on vehicle frame 3, has greatly improved the torsional property of vehicle.
Preferably, described oblique angle propelling rod 18 can be two, for example the first oblique angle propelling rod 180, the second oblique angle propelling rod 182, and corresponding, the first oblique angle propelling rod 180 and the second oblique angle propelling rod 182 are connected to each other at same position with drive-shaft tunnel 4.
In current load-carrying cross country car suspension system, the multiplex steel spring of elastic element, vehicle off-road capability is poor.Rear suspension of cross-country vehicle of the present utility model adopts coil spring 102, two groups of propelling rods, and wherein lateral rod 12 one end are loaded on vehicle bridge 2, and the other end is loaded on vehicle frame 3(for vehicle bridge 2 located lateral); Propelling rod 18 one end in oblique angle are loaded on vehicle bridge 2, and the other end is loaded on drive-shaft tunnel 4, and drive-shaft tunnel 4 is fixed to one another with vehicle bridge 2 and is connected (for vehicle bridge 2 location, front and back).On application Portalachse basis, equip this structure, guarantee the cross-country traveling ability of vehicle, high torsional property.
