Description
Technical field
The utility model relates to a kind of steering wheel assembly of vehicle, particularly the steering wheel of the adjustable engineering truck of a kind of work angle.
Background technology
Engineering truck is the requirement of satisfied different bodily form operator traveling comfort, and the work angle of its steering wheel is arranged to multiple selectable angle.The steering wheel of this adjustable angle is comparatively common at auto trade, but the steering wheel length of automobile is shorter, and operating effort is also less relative to engineering truck, therefore complete machine steering wheel small volume, and the adjustment of work angle is easy to realize.The direction ratio of engineering truck is more sturdy, therefore usually adopts as described in the inhibiting device of Chinese patent CN203780594 steering column inclination angle slide bar when angular adjustment, scheme that slide block locks handle, and this scheme regulates difficulty, effort.Be fixed on cab floor by means of only a mounting seat by whole steering wheel when generally installing in addition, therefore the cantilever of steering wheel is longer, easily rocks.
Summary of the invention
Goal of the invention: the utility model object is that the problem of easily rocking for existing engineering truck steering wheel angular adjustment difficulty, arm length provides a kind of easy for installation, the angular adjustment engineering truck steering wheel that work angle is adjustable flexibly.
Technical scheme: the engineering truck steering wheel that a kind of work angle is adjustable, comprises bottom installation assembly, driving-shaft assembly, rotation fixation assembly, Upper shaft sleeve and bearing circle; Described bottom installation assembly comprises mounting base and Lower shaft sleeve, described Lower shaft sleeve tilt to run through mounting base and along Lower shaft sleeve external diameter and mounting base integrally welded; Be connected with deflector through Lower shaft sleeve bottom described driving-shaft assembly, top is connected with bearing circle through Upper shaft sleeve; Described rotation fixation assembly and Upper shaft sleeve hinged after be fixed in complete machine operator's compartment; Described driving-shaft assembly comprises lower semiaxis, tween drive shaft and upper semiaxis, and described tween drive shaft and lower semiaxis and upper semiaxis are respectively by universal joint articulated, and described two hinge-points are between Upper shaft sleeve and Lower shaft sleeve.The problem that driving-shaft assembly is divided into lower semiaxis, tween drive shaft and upper semiaxis three parts to solve arm length easily to rock by the utility model, makes steering wheel move flexibly, strong adaptability.
Conveniently install and ensure universal-joint smooth transfer moment of torsion in driving-shaft assembly rotary course simultaneously, described tween drive shaft comprises tween drive shaft body and universal-joint connecting portion, passes through spline joint between described tween drive shaft body and universal-joint connecting portion.Can by universal-joint connecting portion in the intrinsic flexible reduction installation difficulty of tween drive shaft in installation process.
The conveniently adjustment of steering wheel angle, described rotation fixation assembly comprises support, controllable gas spring and bearing, described Upper shaft sleeve comprises universal node support and otic placode, described otic placode lies along above universal node support along the radial direction of Upper shaft sleeve, described support is hinged by the universal node support of bearing and Upper shaft sleeve, described controllable gas spring respectively with support and otic placode hinged.During steering wheel angular adjustment with the center of bearing for hinge-point, the flexible angle that can regulate between semiaxis and tween drive shaft of controllable gas spring, the application of bearing makes the resistance of angular adjustment less.
Beneficial effect: the problem that driving-shaft assembly is divided into lower semiaxis, tween drive shaft and upper semiaxis three parts to solve arm length easily to rock by the utility model, makes steering wheel move flexibly, strong adaptability; Can by universal-joint connecting portion in the intrinsic flexible reduction installation difficulty of tween drive shaft in installation process; The application of bearing makes the resistance of angular adjustment less.
