Abstract
The utility model discloses a height bears weight of suspension device behind formula driver's cabin comprises left and right suspension, the complete symmetry of structure of left and right suspension. Mainly form by lock chamber support assembly, undersetting, rubber damping support, hydraulic pressure lock, rubber damping, buffer, rotatory pivot etc. The lock chamber support assembly links firmly with the driver's cabin, and the undersetting links firmly with the frame. The rubber damping passes through interference fit and links to each other with rubber damping support, and both ends are articulated mutually with rubber damping support and undersetting respectively about the buffer. The utility model discloses can the decay vibration of all directions of the combined action that relies on two rubber dampings and buffer. It is good that this structure has a damping property, and the holding capacity is reasonable, and advantages such as compact structure can effectively improve the bearing capacity of driver's cabin and the travelling comfort among the driving motor vehicles.
Description
Technical field
The utility model relates to a kind of automotive accessory, is specifically related to the rear suspension device of truck cab.
Background technology
Along with the development of China Transportation Industry and the progress of science and technology, people require also more and more higher to the traveling comfort of autotruck.Current domestic main autotruck all adopts the rear suspension device with coil spring or air bellow, effectively can improve the traveling comfort of operator's compartment.But due to coil spring and the feature of air bellow self and the restriction of steering room back suspension arrangement space, existing driving cab rear suspension load-carrying capacity is limited, the vibration damping needs of the larger special purpose autotruck of some operator's compartment weight for operator's compartment can not be met, particularly when larger change occurs operator's compartment weight, its effectiveness in vibration suppression will significantly reduce.
Summary of the invention
In order to solve the less problem of existing driving cab rear suspension load-carrying capacity, the utility model provides a kind of can meet the cab rear suspender of special purpose autotruck for heavy Vibration damping of the driver's cab demand.
Specific embodiments is as follows: a kind of cab rear suspender, is made up of left and right suspension, the structure full symmetric of left and right suspension.Each suspension comprises lock bracket assembly, undersetting, rubber damping support, hydraulic lock, rubber damping, energy disperser, rotating axle pin etc.It is characterized in that: lock bracket assembly connects operator's compartment and coordinates with hydraulic lock, rubber damping support bolt and nut fixed hydraulic lock and energy disperser upper end, the energy disperser other end is connected with rotating axle pin.Two rubber dampings are connected by interference fit with rubber damping support, are connected after connection respectively by rotating axle pin with undersetting.Undersetting bolt and nut is connected on vehicle frame.
Another optimal way of the present utility model: rear overhang lock bracket assembly coordinates with hydraulic lock after operator's compartment falls back, coordinates form rear-suspending assembly with remaining part.Adopt heavier-duty hydraulic lock, ensure that its operator's compartment is combined with suspension system when autotruck travels.
Another optimal way of the present utility model: there is rubber damping simple and reliable for structure, center is eccentric orfice, and rubber damping is made up of three parts, there is metallic framework centre, total has different-stiffness in a plurality of directions and moderate finite deformation can occur, and parts reliable operation, the life-span is long.And be interference fit between rubber damping support, use special tooling to be pressed into by compression machine.Rotating axle pin is connected with undersetting through eccentric orfice.
Another optimal way of the present utility model: each suspension utilizes two rubber dampings as elastic element, can bear larger load, meets the vibration damping demand of heavy operator's compartment.Because rubber damping rigidity has nonlinear characteristic, good effectiveness in vibration suppression can be ensured when larger change occurs operator's compartment weight.
Another optimal way of the present utility model: each mounting structure is all equipped with energy disperser, the upper and lower two ends of energy disperser realize hinged with rubber damping support and rotating axle pin respectively.This version can decay the vibration passed over from vehicle frame etc.
The utility model structure is simple, parts reliable operation, and save space, the life-span is long, good stability, and load-carrying capacity is strong, the vibration of all directions that can decay, and can ensure good effectiveness in vibration suppression when larger change occurs operator's compartment weight.
Detailed description of the invention
As shown in Figure of description, described cab rear suspender, is made up of the left and right suspension of full symmetric.Concrete structure of the present utility model and function is described in detail according to Figure of description.Because this structure is symmetrical, therefore only do decomposition description with left side suspension.
Rear overhang lock bracket assembly 6 and operator's compartment are connected, and coordinate after operator's compartment falls back with hydraulic lock 5.Hydraulic lock 5 is connected with rubber damping support 2 by bolt and nut.Energy disperser 9 upper end is hinged with rubber damping support 2 by bolt 7, nut 8, and lower end is hinged by bolt 10 and 11 rotating axle pin.Rubber damping 3 is by compression machine press-in rubber damping support 2 flush fit, and rubber damping 3 center is eccentric orfice, and center, hole is through rotating axle pin 11.Rotating axle pin 11 left end nut 4 is tightened, and right-hand member and bolt 10 pass through screw thread fit.
