Abstract
The utility model discloses a front suspension device with a damper of an engineering vehicle cab, and the suspension device comprises an upper mounting bracket, a front rubber damper, a lower mounting bracket, a shaft pin, a buffer and the like. The combined effect of the front rubber damper and the buffer is employed to attenuate vibrations from various directions. The front rubber damper is connected with the lower mounting bracket via an interference fit, an upper end and a lower end of the buffer are respectively hinged to the upper mounting bracket and a chassis, and the upper mounting bracket is fixedly connected with the cab.
Description
Technical field
The utility model relates to a kind of engineering truck auxiliary device, is specifically related to the front hung holder of construction-vehicle cab.
Background technology
Along with the fast development of medium and heavy truck cap suspension system technology in recent years, the car load traveling comfort is greatly improved.People are also more and more higher to the traveling comfort requirement of engineering truck, and the traveling comfort that how to improve engineering truck has become the problem that the designer is concerned about day by day.The importance that improves the car load traveling comfort is the Cab mounting system of design good damping result.In the suspension system, adopt the rubber damping device that rigidity is big, stroke is little mostly before construction-vehicle cab in the past, buffering and effectiveness in vibration suppression are relatively poor, and it is tired that chaufeur will be felt in the short time.In addition, because engineering truck often travels on abominable road surface, suspension system needs high reliability before the operator's compartment, so engineering truck should adopt semi-floating Cab mounting system.
Summary of the invention
In order to improve the car load traveling comfort of engineering truck, it is a kind of simple in structure, reliable and can absorb significantly simultaneously and semi-floating operator's compartment front hung holder that all directions that decays are vibrated that the utility model provides.Concrete scheme is as follows: a kind of semi-floating operator's compartment front hung holder, formed by last mounting bracket, preceding rubber damping, following mounting bracket, energy disperser, pivot pin etc.It is characterized in that: go up the mounting bracket upper end and be connected by 5 bolts and operator's compartment; Preceding rubber damping and last mounting bracket interference assembling back couple together by pivot pin and following mounting bracket; Following mounting bracket is connected by bolt and nut and chassis; The energy disperser upper end is hinged together by bolt and nut and last mounting bracket, and lower end and chassis are hinged by bolt and nut; Rubber damping linked to each other by nut with following mounting bracket before pivot pin passed.
Another optimal way of the present utility model: have preceding rubber damping simple and reliable for structure, the center is eccentric orfice, the vibration that rigidity is suitable and all directions that can decay pass over, and the big and parts reliable operation of stroke, the life-span is long.And be interference fit between the last mounting bracket, use special tooling to be pressed into by compression machine.Pivot pin passes its center eccentric orfice and is connected with following mounting bracket.
Another optimal way of the present utility model: energy disperser is installed, and it realizes hinged with last mounting bracket and chassis respectively in two ends up and down.Total can strengthen the ability of the vertical vibration that decay passes over from the chassis etc.
Another optimal way of the present utility model: go up mounting bracket and be connected in the front portion of preceding rubber bush and bolt and the operator's compartment at rear portion by set in place, be connected firmly.Last mounting bracket Mechanical Builds is reasonable, in light weight, and load-carrying capacity is strong.
The utility model is simple in structure, and the parts reliable operation is saved the space, and the life-span is long, and is in light weight, good stability, the vibrational energy that all directions that can decay transmit.
