The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified.
Like Fig. 1, shown in 2, said steering shaft section is made up of steering shaft 1, joint fork, center cross 53, breeches pipe assembly 36, castellated shaft 7, spring 8, axle bumper 2, antifriction-bearing box 3, spring leaf 4, rubber ring 5.The steering torque of the main special delivery bearing circle of these parts alleviates the chaufeur injury.And realize angle and axial adjustment respectively through gimbal structure and spline structure.Steering shaft 1 adopts the mode that presses to connect into parts with the joint fork, forms universal-joint parts through center cross and breeches pipe assembly 36 again, and can realize angular adjustment around the axis rotation of center cross.Castellated shaft 7 is that the female splines through its male splines and breeches pipe spare 36 links together and can endwisely slip to realize the axial adjustment function, realizes self-return through spring 8.
Said tube column parts (seeing Fig. 1,2,3,4,7,8) are made up of aluminum component 31, aluminum component 32 and attaching screw 33 thereof, last tubing string soldering member 26, lower tubular column soldering member 27, last tubing string tooth bar locking bar 52, surface bearing 34, rivet 35, spring 8; Radical function is the support steering shaft section and installs and fixes; And steering shaft section can freely be rotated, thereby transmit steering torque.Last tubing string soldering member 26 is to be fitted in through surfaces externally and internally with lower tubular column soldering member 27, and can endwisely slip, and sliding force is controlled by spring 8; Lower tubular column soldering member 27 is fixed on automobile cab, and the tooth of last tubing string tooth bar locking bar 52 and the external tooth of last tubing string soldering member 26 endwisely slip through meshing to control.When regulating, lower tubular column soldering member 27 is fixed, has only last tubing string soldering member 26 to drive steering shaft section and slides together.
Said regulating mechanism (seeing Fig. 1,2,5,6,8,9) is made up of bearing pin 6, assembly 38, regulating spring switch 46, bolt 11, pad 12, handle assembly 13, back-up ring 14, regulating block 15, handle spring 16, handle pivot pin 17, pivot pin 18, pin sleeve 19, plastics cushion collar 20, packing ring 21, bolt 22, and radical function is to regulate vehicle steering angle and axial height to adapt to the chaufeur of different heights.Regulating mechanism mainly is mounted in above the assembly 38; It mainly is rotation drive regulating block 15 through handle assembly 13; Regulating block 15 is pushed tubing string tooth bar locking bar 52 aside, and the tubing string tooth bar locking bar 52 and the tooth of last tubing string soldering member 26 are thrown off, and this moment, chaufeur just can carry out axial adjustment.After handle assembly 13 was decontroled, adjustment piece 15 returns to be gone up the external tooth of tubing string tooth bar locking bar 52 through tooth and last tubing string soldering member 26 this moment and meshes and control axial adjustment.
As shown in Figure 9, said assembly 38 by adjusting shaft 39, spring stop 40, regulating spring 41, plastic sleeve 42, connecting element 43, regulate that outer skeleton 44, a centering spring left side 45, centering spring are right 47, torsion spring 48, yielding rubber 49, cushion plastics 50 and form.Said assembly 38 is through bearing pin 6 and aluminum component 31 bonded assemblys; And can rotate around bearing pin 6; Aluminum component 31 passes through surface bearing 34 and rivet 35 and last tubing string soldering member 26 bonded assemblys, and can rotate, and the center of surface bearing 34 is concentric with the centre of gration of the universal-joint of steering shaft section.Regulatory function is locked and opened to assembly 38 through regulating spring switch 46, rotates when 13 rotations of regulating handle assembly drive regulating block 15, opens thereby drive regulating spring switch 46; Assembly 38 is axial free adjustment just; Moving axially of assembly 38 drives aluminum component 31 through surface bearing 34 rotations, drives the universal-joint rotation of steering shaft, thereby realizes the angular adjustment of bearing circle; After handle assembly 13 unclamped, regulating spring switch 46 self-returns pinned endwisely slipping of assembly 38.So just fixed steering swivel system.
The utility model is a steering angle and axial bilaterally adjustable column assy in sum, but after release handle the position self-return of steering handwheel, to adapt to the operating habit of chaufeur; Improved driver comfort; Again can be when automobile generation head-on crash, the absorption portion Impact energy has reduced the degree that driver and crew are hurt; Improve vehicle drive traveling comfort and passive satety, be mainly used in commercial vehicle/comm..vehicle.
