Abstract

The utility model discloses a semi-floating cab front suspension device. The suspension device comprises an upper supporting bracket, a lower mounting bracket, a front rubber damper, a buffer, a rotation shaft pin, a lifting shaft pin and the like. The suspension device is characterized in that the upper supporting bracket and the upper end of a welding bracket assembly are fixed connected to the cab; after being in interference fit with the upper supporting bracket, the front rubber damper is connected to the lower mounting bracket by virtue of the rotation shaft pin; the buffer is respectively hinged with the upper supporting bracket and the rotation shaft pin by virtue of bolts and nuts; the rotation shaft pin is connected to the lower mounting bracket; and the lower mounting bracket is fixedly connected to a frame by virtue of bolts and nuts. According to the utility model, by virtue of the combined actions of the front rubber damper with a complicated structure and the buffer, vibrations in various directions can be damped. The cab moves strictly along a track during an overturn procedure, so that the stability is good.

Description

A kind of semi-floating operator's compartment front hung holder
Technical field
The utility model relates to a kind of automobile auxiliary device, is specifically related to the front hung holder of truck cab.
Background technology
Along with the development of China Transportation Industry, and along with progress of science and technology.The traveling comfort of people's counterweight card requires also increasingly high.How improving heavily, the riding comfort of card has become the problem that the designer is concerned about very much.The vibration that road roughness causes is passed to operator's compartment through tire, chassis suspension, vehicle frame.The effect of Cab mounting mainly has been to connect vehicle frame and operator's compartment securely, the vibration of decay each side.The semi-floating Cab mounting suspends preceding mostly and adopts the rubber damping device, and its advantage is: (1) is simple in structure, low price; (2) in light weight, volume is little, be connected firmly; (3) elastomeric material has internally-dampedly, itself has the function of damped vibration.The rubber damping device can absorb and transform the vibrational energy that three dimensional space transmits simultaneously, can stand multidirectional disturbance, and adapt to the service condition under the stressed complex conditions; Its dynamic stiffness is greater than quiet rigidity, and shock stiffness even receive sizable impact, also is difficult for impaired and destruction greater than quiet, dynamic stiffness.In some, on the low side car, often adopt the rubber damping device.In heavy card field, to different operating conditions environmental and selling price, the semi-floating Cab mounting has its application places.
Summary of the invention
In order to improve cab comfort, stability, the semi-floating operator's compartment front hung holder that the utility model provides a kind of simple in structure, the tilt-stable and all directions that can absorb simultaneously and decay to vibrate.Concrete scheme is following: a kind of semi-floating operator's compartment front hung holder, form by upper support frame, lifting pivot pin, energy disperser, rotating axle pin, preceding rubber damping, following mounting bracket, welding support assembly etc.It is characterized in that: the upper end and the operator's compartment of upper support frame, welding support assembly are connected; Preceding rubber damping and upper support frame interference assembling back couple together through rotating axle pin and following mounting bracket; Energy disperser is hinged together with upper support frame and rotating axle pin respectively through bolt and nut, and rotating axle pin links to each other with following mounting bracket; Following mounting bracket is connected through bolt and nut and vehicle frame.
Another optimal way of the utility model: have preceding rubber damping simple and reliable for structure, the parts reliable operation, the life-span is long.Preceding rubber damping is pressed into upper support frame, and rotating axle pin passes its center eccentric orfice and is connected with following mounting bracket.
Another optimal way of the utility model: energy disperser is installed, and it realizes hinged with upper support frame and rotating axle pin respectively in two ends up and down.Total can strengthen the ability of the vibration that decay passes over from vehicle frame etc.
Another optimal way of the utility model: the lifting pivot pin is installed on the upper support frame through interference fit, and the lifting pivot pin connects the lifting cylinder of upset operator's compartment, makes suspension system play the function that supports driver's cab turnover simultaneously.
Another optimal way of the utility model:, make operator's compartment steadily reliable in whole switching process because the parts such as the relative coil spring of deflection of preceding rubber damping are less.
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.The upset operator's compartment has so just guaranteed the stability of switching process almost by strict orbiting motion.
