Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
The two transverse arm torsion bar spring independent suspension front axle assembly of integrated form see Fig. 1, Fig. 2, Fig. 3, comprises integrated form subframe 1, bumper 2, torsion bar spring 3, adjusts and turn round support 4, wheel hub 5, brake disc 6, steering swivel 7, Top Crossbeam 8, swivel pin angle and outward camber tunable arrangement 9, lower supporting rod 10, lower cross arm 11, brake clamp 12, hyphen pull bar 13, right steering rocking arm 14, upper strut 15, middle intermediate rod 16, left steering rocking arm 17.
Wherein, Top Crossbeam 8 is inner adopts splined to be integral structure with torsion bar spring 3 front end, and is connected with integrated form subframe by bolt by the integral structure that Top Crossbeam 8 connects with torsion bar spring 3, and torsion bar spring 3 rear end and tune are turned round support 4 and passed through splined; Bumper 2 upper end is arranged on integrated form subframe 1, and lower end is arranged on lower supporting rod 10; Lower cross arm 11 is inner passes through Bolt Connection with integrated form subframe 1, and upper strut 15 and lower supporting rod 10 front end are connected with integrated form subframe 1 by rubber bush, and rear end is bolted to connection with Top Crossbeam 8 and lower cross arm 11 outer end respectively.Swivel pin angle and outward camber tunable arrangement 9 are arranged on integrated form subframe 1; Steering swivel 7 is connected by ball pivot with Top Crossbeam 8 and lower cross arm 11 outer end, forms main pin axis; Brake disc 6 and brake clamp 12 are assembled into hydraulic disk brake assembly, and brake assembly is assembled into one by Bolt Connection and wheel hub 5, and be enclosed within tapered roller bearing, tapered roller bearing is enclosed within steering swivel 7 axle head, clamps with shaft shoulder dowel bolt; Left steering rocking arm 17, its upper and lower end face, one end is connected with hyphen pull bar 13 and middle intermediate rod 16 respectively, and the other end connects with drag link.Right steering rocking arm 14, its upper and lower end face, one end is connected with hyphen pull bar 13 and middle intermediate rod 16 respectively.Left steering rocking arm 17 and right steering rocking arm 14 are enclosed within rotating shaft, and rotating shaft is installed on integrated form subframe 1 by rocker arm support.
In this example, this assembly is the front axle assembly integrating two transverse arm torsion bar spring independent suspension system, breakaway-element steering swivel system, hydraulic disk brake system, integrated form subframe, and this assembly axle load Applicable scope is 2 to 3.5 tons.This front axle assembly compensate for domestic commercial vehicle 2 to 3.5 tons of independent suspension blank sequence.
In this example, adopt two transverse arm torsion bar spring independent suspension, reduce the Frame and Body vibration caused by Uneven road, eliminate the phenomenon of the continuous beat of wheel flutter; Decrease nonspring carried mass simultaneously, improve vehicle riding comfort; Swivel pin angle and outward camber tunable arrangement 9 by regulating Kingpin inclination angle and camber angle according to vehicular applications, improve vehicle and travel road-holding property, are applicable to the vehicle of the different purposes in same chassis.
