The specific embodiment
With reference to the accompanying drawings 1, shown in accompanying drawing 2, accompanying drawing 3 and the accompanying drawing 4, the present invention is carried out detailed explanation.
The utility model propons weld assembly 7 left and right sides are connected with steering swivel 14 through stub 9; Steering swivel 14 is connected with wheel hub 13; Wheel hub 13 is connected with wheel 4, and vehicle is suffered to be delivered on the propons weld assembly 7 through wheel 4, wheel hub 13, steering swivel 14 from the various load of ground-surface successively.Propons weld assembly 7 front sides are connected with four longitudinal ties 8 through oscillating bearing, and four longitudinal ties 8 connect to ground through oscillating bearing, and four longitudinal ties 8 are installed vehicle frame front end both sides respectively, and every side is provided with two and parallel.Propons weld assembly 7 rear sides are through oscillating bearing lateral connecting rod 2, and lateral connecting rod 2 connects to ground through oscillating bearing, and propons weld assembly 7 both sides are respectively through the outstanding cylinder 3 of oscillating bearing, and outstanding cylinder 3 connects to ground through oscillating bearing.Propons weld assembly 7 is that perk middle part, both sides is recessed, adopts steel plate to be welded into rectangle box cross section structure.Like this; Between propons and the vehicle frame; Formed many groups connecting rod mechanism through longitudinal tie 8, lateral connecting rod 2 and outstanding cylinder 3, organize the connecting rod mechanism function is separate mutual restriction again more, makes front axle assy can realize all around, up and down and compound motion with respect to vehicle frame; And what outstanding cylinder adopted is the outstanding cylinder of oil gas, and actv. absorbs from the various impacts of ground-surface so more.
Said stub 9 is fixing through plug screw 20 with propons weld assembly 7, in order to prevent stub and propons weld assembly generation relative rotary motion.
Said stub 9 is provided with Upper shaft sleeve 19 and Lower shaft sleeve 15 with steering swivel 14 junctions, is used to bear between stub 9 and the steering swivel 14 because the mechanical wear that rotatablely moves and produce is avoided the steering swivel wearing and tearing.
Thrust bearing 17 and following thrust bearing 16 are set between said propons weld assembly 7 and the steering swivel 14 are used to bear the axial force between propons weld assembly 7 and the steering swivel 14; Last thrust bearing 17 usefulness expansion pin 18 are connected fixing with propons weld assembly 7, following thrust bearing 16 usefulness expansion pin 18 are connected fixing with steering swivel 14.Because the setting of upper and lower thrust bearing has avoided the direct contact of propons weld assembly and steering swivel to produce wearing and tearing.
Said steering cylinder 6 is installed on spindle arm 5 and the propons weld assembly 7 through oscillating bearing and bearing pin, and tierod 1 is installed to through oscillating bearing and bearing pin on the spindle arm 5 of the left and right sides, and spindle arm 5 is connected with steering swivel 14 through bolt.The flexible drive spindle arm of left and right sides steering cylinder 6 rotates around stub, realizes turning to function, and simultaneously, tierod 1 connection both sides spindle arm 5 guarantees that two-wheeled rotates synchronously.
Said brake disc 11 is installed on the wheel hub 13 through bolt, and drg 12 is installed on the brake support frame 10 through bolt, and brake support frame 10 is installed on the steering swivel 14 through bolt.Between brake support frame 10 and drg 12, be provided with the accent feeler, in order to the centering of regulating brake and brake disc 11.
Working process is described: the outstanding cylinder 3 on the propons, lateral connecting rod 2, longitudinal tie 8 connect to ground, and wheel 4 contacts with ground.Be delivered on the propons weld assembly 7 through wheel 4, wheel hub 13, steering swivel 14, stub 9 successively from the ground-surface impact load.Propons weld assembly 7 passes to vehicle frame through outstanding cylinder 3, lateral connecting rod 2, longitudinal tie 8 with the ground-surface impact load.In the impact load transmittance process, propons weld assembly 7 through four longitudinal ties 8 can realize about vehicle frame, left rotation and right rotation absorbs impact load; Propons weld assembly 7 is through the flexible absorption impact load of outstanding cylinder 3; Propons weld assembly 7 limits the amplitude that swings through the lateral connecting rod 2 that connects to ground.Like this, propons can fully absorb impact load, and actv. is realized shock-absorbing function more.Turn to function to pass through the flexible drive spindle arm 5 of steering cylinder 6, spindle arm 5 drives wheel hub 13, and wheel hub 13 drives wheel 4 and turns to, and tierod 1 connection both sides spindle arm 5 guarantees that two-wheeled rotates synchronously.
