Abstract
The utility model relates to vehicle component technical field, specifically relates to a kind of locking bolt support with vibration-damping function.Its lower bracket offers the mounting hole of walking for lock pin, steel bushing is embedded in this mounting hole, the outer ring of rubber bush and steel bushing interference fit, and by lock pin casing limit between two rubber bushs, lock pin is placed in this lock pin sleeve pipe.Be provided with the bump rubber taken the shape of the letter U between two blocks of side plates of upper bracket, two blocks of side plates and bump rubber offer the mounting hole of walking for bolt of rear end plate, bump rubber and upper bracket are installed fixing by bolt of rear end plate through this mounting hole.This locking bolt support is with bump rubber and rubber bush, and ground of can decaying passes to the vibration of operator's compartment, reduces the impulsive force that bears of operator's compartment, improves the travelling comfort of operator's compartment, improves operator's compartment service life.Lock pin sleeve pipe adopts design for disassembly, can prevent lock pin from wearing and tearing.When after lock pin casing wear, without the need to changing locking bolt bracket assembly, only change lock pin sleeve pipe and lock pin.
Description
Technical field
The utility model relates to vehicle component technical field, specifically relates to a kind of locking bolt support with vibration-damping function.
Background technology
Heavily card operator's compartment is with locking bolt bracket assembly at present, and one of effect of operator's compartment locking bolt support is for supporting operator's compartment, carrying operator's compartment weight, and another act as and locks with rear suspension mechanism, prevents driver's cab turnover.At present, generally adopt between locking bolt support and operator's compartment and be rigidly connected, the lock pin of locking bolt support coordinates with also adopting rigidity between hydraulic lock support, when vehicle is in jounce condition for a long time, very easily cause the damage of operator's compartment, locking bolt support and hydraulic lock, this just needs to change whole locking bolt bracket assembly.
Utility model content
For the technical matters existed in prior art, the purpose of this utility model is to provide that a kind of cushioning performance is good, the locking bolt support of repair and replacement easily with vibration-damping function.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of locking bolt support with vibration-damping function, be made up of the upper bracket be welded to one another and lower bracket, two blocks of side plates of described lower bracket offer the mounting hole of walking for lock pin, steel bushing is embedded in this mounting hole, the outer ring of rubber bush and steel bushing interference fit, by lock pin casing limit between two rubber bushs, described lock pin be placed in this lock pin sleeve pipe and its end by lock pin nut locking.
In the locking bolt support of this band vibration-damping function, the bump rubber taken the shape of the letter U is provided with between two blocks of side plates of described upper bracket, two blocks of side plates and bump rubber offer the mounting hole of walking for bolt of rear end plate, bump rubber and upper bracket are installed through this mounting hole and to be fixed and its end is locked by flange surface nut by bolt of rear end plate.
The locking bolt support of band vibration-damping function of the present utility model, its beneficial effect shows:
This locking bolt support is with bump rubber and rubber bush, and ground of can decaying passes to the vibration of operator's compartment, reduces the impulsive force that bears of operator's compartment, improves the travelling comfort of operator's compartment, improves operator's compartment service life.
Lock pin sleeve pipe adopts design for disassembly, can prevent lock pin from wearing and tearing.In addition when after lock pin casing wear, without the need to changing locking bolt bracket assembly, only change lock pin sleeve pipe and lock pin, vehicle maintenance more for convenience.
Accompanying drawing explanation
Fig. 1 is the structural representation of the locking bolt support of band vibration-damping function of the present utility model.
Fig. 2 is the A direction view in Fig. 1.
Fig. 3 is the mounting structure schematic diagram of the locking bolt support of band vibration-damping function of the present utility model.
Detailed description of the invention
For further describing the utility model, below in conjunction with drawings and Examples, the utility model is described in further detail.A kind of locking bolt support 2 with vibration-damping function shown in Fig. 1 and 2, is made up of bump rubber 11, bolt of rear end plate 12, upper bracket 13, flange surface nut, lower bracket 15, steel bushing 16, lock pin sleeve pipe 17, rubber bush 18, lock pin 9 and lock pin nut 10.
Upper bracket 13 and lower bracket 15 welding fabrication, two blocks of side plates of lower bracket 15 offer the mounting hole of walking for lock pin 9, and steel bushing 16 to be embedded in this mounting hole and to weld.
The outer ring of rubber bush 18 and steel bushing 16 interference fit, be pressed in steel bushing 16 by press by rubber bush 18, and rubber bush 18 radial direction can plastic deformation, thus damped vibration, improve and drive travelling comfort.
Spacing by lock pin sleeve pipe 17 between two rubber bushs 18, lock pin 9 is placed in this lock pin sleeve pipe 17 and its end is locked by lock pin nut 10.
The bump rubber 11 taken the shape of the letter U is provided with between two blocks of side plates of upper bracket 13, two blocks of side plates and bump rubber 11 offer the mounting hole of walking for bolt of rear end plate 12, bump rubber 11 and upper bracket 13 to be installed fixing and its end through this mounting hole and are locked by flange surface nut 4 by bolt of rear end plate 12.
Refer to Fig. 3, locking bolt support 2 is connected with operator's compartment 1 by bolt of rear end plate 12, and lock pin sleeve pipe 17 and hydraulic lock 3 free-running fit be fixed in lower support 4, lower support 4 is affixed with frame beam 5, under hydraulic lock 3 acts on, realizes upset and the locking of operator's compartment 1.
When the vehicle is running, when frame beam 5 bears next road bump, frame beam 5 by vibration passing to lower support 4, part vibration is attenuated by lower support 4, the vibration of another passes to the lock pin sleeve pipe 17 on locking bolt support 2 by hydraulic lock 3, lock pin sleeve pipe 17 bears part vibration, weares and teares with hydraulic lock 3.Another part vibration is decayed by the rubber bush 18 on lock pin 19.Because being equipped with bump rubber 11 between operator's compartment 1 and locking bolt support 2, locking bolt support 2 by remaining vibration passing to operator's compartment 1 time, bump rubber 11 by absorb wherein a part vibration.
Above content is only to design example of the present utility model and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
