Abstract
The utility model relates to a cab rear suspension device and belongs to the field of vehicle auxiliary devices. The utility model comprises a chassis and a rear suspension vertical column; one end of the rear suspension vertical column is connected with the chassis; the other end is respectively connected with an upper cross beam, a rear cross beam and a hydraulic lock; one end of the hydraulic lock is sequentially connected with a shock absorber and an elastic device; the other end of the elastic device is linked to the rear suspension vertical column. The spiral spring and the shock absorber in the utility model are arranged in an inclination way; the upper cross beam and the rear cross beam are integrated to support with the rear suspension vertical column; in the structure, the positioning performances are more reliable; the bearing capacity can be improved; the functions can both completely meet the comfort requirements, and lower vertical vibration and reduce transversal brake; meanwhile, the utility has the advantages of saving arrangement space, lowering manufacturing cost, being economic and practical, integrated structure, elegant design, novel structure, etc.
Description
Technical field
The utility model relates to a kind of vehicle auxiliary device, specifically a kind of operator's compartment rear suspension device.
Background technology
We know that the operator's compartment rear suspension device is to be fixed on the vehicle frame, operator's compartment are played the effect of vibration damping in driver's cab turnover and car load driving process.But the design of existing operator's compartment rear suspension device is not quite reasonable, causes that easily operator's compartment is vertical, the increase of cross travel, can not actv. guarantees the stability and the traveling comfort of operator's compartment in normal upset, return and the driving process of operator's compartment.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, easy to operate, can effectively slow down the operator's compartment rear suspension device of the vibration of operator's compartment.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of operator's compartment rear suspension device, comprise vehicle frame and after the column that suspends, after column one end that suspends be connected with vehicle frame, the other end links together with entablatrance, after cross member, hydraulic lock respectively, hydraulic lock one end connects shock absorber and springing successively, on the column that suspends after the springing other end is connected to.
Column one end that suspends after described is connected with vehicle frame by bolt.
Described entablatrance and after cross member are by on the column that suspends after being bolted to.
Described springing is a coil spring.
Suspend after described column, hydraulic lock, coil spring and shock absorber connects to form triangle.
Coil spring of the present utility model and shock absorber are in tilted layout, entablatrance and after cross member and after the suspend general frame of column, structurally fixed performance is more reliable, and load-carrying capacity improves, and can satisfy the traveling comfort requirement fully on function, the vertical shake of can decaying, can decay again and laterally brake, save arrangement space simultaneously, reduce manufacturing cost, economical and practical, have advantages such as unit design is ingenious, novel structure.
Description of drawings
Fig. 1 is the utility model structural representation.
Column, 2. entablatrance, 3. operator's compartment, 4. after cross member, 5. hydraulic lock, 6. shock absorber, 7. coil spring, 8. vehicle frame wherein suspend after 1..
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, after the column 1 that suspends link to each other with vehicle frame 8 by bolt, form a firm supporter; Entablatrance 2 and after cross member 4 form a fixed frame by on the column 1 that suspends after being bolted to; After a suspend end and the hydraulic lock 5 of column 1 be installed together, coil spring 7 with suspend the other end of column 1 and link to each other after shock absorber 6 tilts to be installed on hydraulic lock 5, after suspend column 1, hydraulic lock 5, coil spring 7 and shock absorber 6 be mounted to triangle.Like this, when operator's compartment 3 when trip shaft overturns, rear suspension device automatically replies free state; When operator's compartment 3 fell after rise, operator's compartment and rear suspension device were wanted recombination, had certain vertical, cross travel owing to cooperate with rear suspension device during accumulated error operator's compartment 3 fallings of part, and former structure can not well be docked.And the utility model can solve this problem, and vertical, the cross travel of decay greatly meets the demands.Operator's compartment 3 falls after rise on hydraulic lock 5 simultaneously, the pressure that is produced when being fallen after rise by coil spring 7 and shock absorber 6 decay operator'ies compartment; In the car load driving process, after the triangle that column 1, shock absorber 6, coil spring 7, hydraulic lock 5 form that suspends, the suspension system that decayed to a great extent is delivered to the vibration of operator's compartment 3, more can make operator's compartment 3 reduce the damage that operator's compartment 3 is caused owing to the chassis vibration in the process of moving, traveling comfort is stronger.
Claims (5)
1. operator's compartment rear suspension device, comprise vehicle frame and after the column that suspends, after column one end that suspends be connected with vehicle frame, it is characterized in that: the other end links together with entablatrance, after cross member, hydraulic lock respectively, hydraulic lock one end connects shock absorber and springing successively, on the column that suspends after the springing other end is connected to.
2. operator's compartment rear suspension device according to claim 1 is characterized in that: column one end that suspends after described is connected with vehicle frame by bolt.
3. operator's compartment rear suspension device according to claim 1 is characterized in that: described entablatrance and after cross member are by on the column that suspends after being bolted to.
4. operator's compartment rear suspension device according to claim 1 is characterized in that: described springing is a coil spring.
