Description
Technical field
The utility model belongs to commercial car technical field, is related to a kind of truck cap rear-suspending of new construction.
Background technology
Distance rod has the tendency that the shortcomings that aggravation rolls in the structure used at present, and distance rod is shorter, and arrangement is more inclined
Tiltedly, this trend is more violent；It is fixed since it relies only on a point, when driver's cabin moves forward and backward, it is possible to lateral deviation occur
The problem of.And single transverse arm is when driver's cabin moves up and down, the distance in two motor points is not same, and the bushing of swing rod junction is firm
Degree must sufficiently low distance change that could be between compensation campaign point, can just have preferable comfort, but when rigidity is relatively low without
The transverse direction of method limitation driver's cabin moves on to, and occupied space is big.
Utility model content
The technical issues of solution of the utility model, is to provide a kind of watts link truck structure driving cab rear suspension, is
One kind can avoid the shortcomings that common guide frame, and not lose the guide frame of its comfort requirement, with reference to passenger car chassis
Watts link structural shape in suspension system meets comfort and reliability requirement, and to seek survival by Transform Type design to reach
Production and the good manufacturability of assembling.
The technical solution of the utility model is:A kind of watts link truck structure driving cab rear suspension, which is characterized in that
It is made up of part：Lockable mechanism, upper bracket, vibration absorption unit, left lower bracket, right lower bracket, watts link；Watts link packet
Containing single watts link A, single watts link B, hinge C；Rear-suspending and driver's cabin are carried out locking by lockable mechanism；Vibration absorption unit is spiral shell
Revolve spring damper；Watts link is that single watts link A, list watts link B are attached to hinge C both ends composition；Outside wherein hinge C
Hold two Kong Yudan watts links A, single watts link B upper end hole connection, hinge C interstitial holes and connection among upper bracket；
Lockable mechanism is fixed on upper bracket, on the upper end both ends fixed to upper bracket of two vibration absorption units, two vibration absorption units
Lower end be connected respectively on left lower bracket and right lower bracket, the lower end of single watts link A of watts link and single watts link B
It is connected respectively on left lower bracket and right lower bracket.
Preferably, three holes of hinge are each equipped with rubber bushing.
Preferably, lockable mechanism is bolted on upper bracket.
Preferably, single watts link A, single watts link B lower ends are equipped with rubber bushing in hole.
Preferably, the upper end of two vibration absorption units is bolted on upper bracket.
Preferably, the lower end of two vibration absorption units is bolted to respectively on left lower bracket and right lower bracket.
Preferably, single watts link A of watts link and list watts link B obtains lower end and is bolted to lower-left branch respectively
On frame and right lower bracket.
The utility model has the technical effect that：
The structure is with existing structure main difference is that the movement guide mechanism of this rear-suspending is using watts link rather than common
Distance rod or single transverse arm.Driving cab rear suspension is using watts link structure as guiding mechanism, you can to ensure that driver's cabin is transported
Dynamic stability and controllability can also optimize the rigidity of cab mounting to promote comfort；Simultaneously because the simplification of structure,
Weight and cost can be reduced.
Description of the drawings
Fig. 1：Watts link rear suspension structure schematic diagram；
Fig. 2：Watts link assembly structure schematic diagram.
Wherein, lockable mechanism 1, upper bracket 2, vibration absorption unit 3, left lower bracket 4, right lower bracket 5, watts link assembly 6；It is single
Watts link A, single watts link B, hinge C.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The structure of the utility model is as shown in Figure 1.
A kind of watts link truck structure driving cab rear suspension of the utility model, is made up of part：Lockable mechanism
1st, upper bracket 2, vibration absorption unit 3, left lower bracket 4, right lower bracket 5, watts link assembly 6；Watts link assembly 6 includes single watt
Connecting rod A, single watts link B, hinge C.
Lockable mechanism 1 is using the common hydraulic locking device of current rear-suspending or mechanical locking device, for by rear overhang
It puts and carries out locking with driver's cabin.Upper bracket 2, left lower bracket 4, right lower bracket 5 are hardware.Vibration absorption unit 3 uses mesh
It can also be air spring damper that front and rear suspension common structure, which can be helical spring shock absorber,.
Watts link assembly 6 include watts link,
Watts link assembly 6 is that single watts link A, list watts link B are attached on the hole at hinge C both ends and are formed；Dan Wa
Special connecting rod A, single watts link B are metal rod, and lower end is equipped with rubber bushing；Hinge C be hardware, above there are three
Hole is each equipped with rubber bushing, and the wherein Kong Yudan watts links A of outer end two, list watts link B do not fill the Kong Lian of rubber bushing
It connects, interstitial hole is connect with upper bracket 2.
Lockable mechanism 1 is bolted on upper bracket 2, and the upper end of two vibration absorption units 3 is bolted to branch
On frame 2, the interstitial hole of the hinge C of watts link assembly 6 is connected on upper bracket 2, and spiral shell is used in the lower end of two vibration absorption units 3 respectively
It tethers and is connected on left lower bracket 4 and right lower bracket 5, single watts link A of watts link assembly 6 is equipped with rubber with single watts link B
One end of glue bushing is bolted to respectively on left lower bracket 4 and right lower bracket 5.
In cab motions, since the characteristic of watts link structure in itself can ensure what hinge C was connect with upper bracket 2
Can only be in vertical motion between central point and vehicle frame, the relative motion between such driver's cabin and vehicle frame only move vertically or
Person rotates around hinge C interstitial holes, it is impossible to transverse shifting occur；In Ackermann steer angle, hinge rotates about the axis thereof, and roll force is by subtracting
Shake unit undertakes, and such vibration absorption unit rigidity in design can accomplish lower to promote comfort, not need to through big rigidity
Damper prevent excessive inclination.
The utility model is using guiding mechanism of the watts link structure as driving cab rear suspension.
