Abstract
The utility model relates to a two-direction hung damping chair. As the utility model carries out the mechanical elastic hanging on the vertical direction and the horizontal direction, the utility model simultaneously carries out the damping on the vertical direction and the horizontal direction. The utility model is favorable for the damping on the short shaft distance non-road vehicles of construction vehicles, agricultural tractors, and especially reduces the vibration influence of the vehicle pitch vibrations on the utility model. In addition, the damping effect of the utility model on the vertical direction is better than the existing various vertical mechanical hanging seats.
Description
The utility model belongs to the Vehicle Engineering field, is used for off highway vehicles such as construction vehicle, farm tractor.
At present, various driver's chairs all adopt unidirectional vertical resilient suspension mode.This oscillation damping method can not reduce the vibration of the driver's chair that causes owing to the vehicle pitch vibration.This pitch vibration, for Construction traffic and farm tractor etc., violent especially.The comfortableness of driver's chair is poor, the grievous injury workers'health.
In December, 1977, SAE770705 reported a kind of research situation of two-way suspension seat, but what adopt owing to the vertical hanging of this seat is that the hydraulic servo vibration damping makes the armchair structure complexity, makes difficulty, costs an arm and a leg.In addition, the vertical vibration damping suspension of this seat place horizontally suspend below, connect with vehicle frame, this is with regard to the horizontal rigidity of unnecessary increase vertical hanging mechanism.
The purpose of this utility model is, works out a kind of simple in structure, easy to make, driver's chair that can two-way vibration damping.
Structural shape of the present utility model such as accompanying drawing.
When the driver was in normal operating state, its body wt made seat 7 produce displacement downwards along vertical damping guide rail 1.At this moment, vertical hanging spring 2 will bear the whole weight of driver and seat.The vertical hanging spring is two steel helical springs, and two ends are separately fixed on transition bracket 5 and the seat 7.Spring is all imbedded in the transition bracket.Seat support 6 is made by two fine steel tubes, and two ends are hinged with seat 7 and transition bracket 5 respectively, play stable seat and move both vertically.Transition bracket 5 is by two column type horizontal guide rails 3 and vehicle frame rigid attachment in vertical direction, but can be free to slide on the horizontal direction of front and back.Simultaneously, on the horizontal direction of front and back, cross transition bracket and also horizontally suspend steel helical spring and vehicle frame resilient connection by two.Therefore, transition bracket can only slidably reciprocate within the specific limits along horizontal guide rail.
Horizontally suspend the rigidity of spring, by the loading on the seat (comprising seat-weight) intrinsic frequency of the vibrational system formed of spring and the seat attitude horizontal direction mechanical impedance property and the ISO2631(1978 of human body therewith) decision.The rigidity of vertical hanging spring, the intrinsic frequency and the human body of the vibrational system formed of spring are sat the mechanical impedance property and the ISO2631(1978 of attitude vertical direction therewith by the loading on the seat (comprising seat-weight)) decision.
The utility model has the advantages that because seat can carry out vibration damping to driver's seat on sagittal horizontal direction, this just greatly reduces the front and back pitch vibration of driver's chair.This point for SWB off highway vehicles such as Construction traffic, farm tractor, has then solved anxious for a long time to be solved and insurmountable problem.In addition, this two-way suspension seat effectiveness in vibration suppression in vertical direction also is better than the existing mechanical suspension seat.
