Description
Technical field
The present invention relates to semitrailer construction applications.
Background technology
The tail support assembly of semitrailer is generally if State Bureau is in a name of on 2 26th, 2014 bulletins in the prior art
Shown in " three axle semi-mounted vehicle bridge lifting systems ", the Chinese invention patent of Application No. " 201320498519.8 ", the case is disclosed
A kind of typical three axles semi-mounted vehicle bridge.However, people also found in actual use, when vehicle is being turned or only single wheel
Press through when jolting road surface, great lateral shift power will be born on the rear-mounted of semitrailer, once the biasing force exceeds rear-mounted
Attachment force between Rear frame, then the problems such as will appear from back axle skew or even disconnect, riding stability and safety to vehicle
Property brings strong influence.
The content of the invention
The present invention is directed to problem above, it is proposed that a kind of delicate structure, connective stability are good, enabling capabilities are strong and spacing energy

Embodiment
As Figure 1-3, the semitrailer includes rear-mounted 4 and Rear frame 5 to the present invention, and the rear-mounted 4 includes fixing
Framework 41 and at least one axletree 42, the two ends of the axletree are hinged with least one pair of wheel, axletree when vehicle is travelled
Do not rotate, wheel is passively rotated by frictional ground force, the one end of the fixed frame 41 away from semi-trailer tail is consolidated with Rear frame 5
It is fixed to be connected, the Rear frame 5 and the relocatable top for being connected to axletree 42 of fixed frame 41；The tail support assembly 6
Including at least one rear gasbag 61 and at least one rear shock absorber 62, the rear gasbag 61 is connected to wheel by connecting seat 610
Between axle 42 and Rear frame 5, the rear shock absorber 62 is connected between axletree 42 and Rear frame 5 by contiguous block 620 so that
The Rear frame and the relocatable top for being connected to axletree of fixed frame；
The tail support assembly 6 includes cross spacing component 63, and the cross spacing component 63 includes at least one fix bar
631 and at least two fixed blocks 632, fixed block 632 is respectively fixedly connected with fixed frame 41 and axletree described at least two
On 42, the rear limit shaft and the phase of two fixed block 632 of the two ends of the fix bar 631 respectively by being set along semi-mounted vehicle-width direction
It is hinged.Thus it is possible, on the one hand, so that Rear frame and axletree can the relative motion above and below doing down to a certain degree so that the gas with reference to after
Capsule and rear shock absorber filtering road bump, lift the stability of cargo transport；On the other hand, Rear frame and wheel can effectively be prevented
Occurs laterally opposed displacement between axle（I.e. along the axial direction of axletree）, so that the rear-mounted of semitrailer can integrally bear bigger
Lateral shift power, and then the axletree that avoids in rear-mounted of high degree is the problems such as skew occur or even disconnect, to car
Qualitative and security bring great lifting.
Representative discussion is carried out to fix bar and the quantitative relation of fixed block with two kinds of concrete structures below：
Concrete structure one：The cross spacing component 63 includes two fix bars 631 and three fixed blocks 632, the fixed block
632 points are a fixed block 1 and two fixed blocks 2 6322, and the fixed block 1 is fixedly connected on axletree 42
On, the fixed block 2 6322 is fixedly connected on fixed frame 41 and is symmetrical arranged along fixed block 1, fixed described in two
One end of bar 631 be hinged respectively with two fixed blocks 2 6322 and fix bar 631 described in two the other end with fixed block one
6321 are hinged.So as to form a complete isosceles triangle between two fix bars and a part for fixed frame, make
Vehicle is obtained when bearing lateral shift power, is further ensured that by stable triangular structure and lifts rear vehicle shaft and fixed frame
Stability and structural strength between frame.
The end that fix bar described in two is hinged with fixed block one is connected as a single entity.So as to effectively improve the whole of fix bar
Body and steadiness.
Concrete structure two：The cross spacing component includes two fix bars and four fixed blocks, and fixed block described in two is consolidated
Surely it is connected on axletree, fixed block is fixedly connected on fixed frame described in two in addition, the two ends of the fix bar are cut with scissors respectively
It is connected on and is connected to the fixed block of axletree and is connected on the fixed block of fixed frame.So as to may be such that vehicle is being born laterally partially
By two fix bar collective effects during shifting power, the lateral shift power is shared jointly, and then greatly ensure that axletree and fixation
Stability and structural strength between framework.At the same time, it can be divided into according to the difference of two fix bar position relationships following several
Situation：
Situation one：Fix bar be arranged in parallel described in two.So as to form one between two fix bars, axletree and part fixed frame
Stable rectangle.
Situation two：Fix bar is staggered described in two.So as to be formed between two fix bars, axletree and part fixed frame
Two stable triangles.
Situation three：Spacing is left between fix bar described in two and the two is in 1 ~ 179 ° of angle.So as in two fix bars, car
A stable isosceles trapezoid is formed between wheel shaft and part fixed frame.
The tail support assembly 6 also includes longitudinal spacing component 64, and the longitudinal spacing component 64 includes at least one pair of
Spacing connecting rod 640, spacing connecting rod 640 is corresponding with an axletree 42 described in a pair, length of the spacing connecting rod 640 along semitrailer
Spend direction to set, one end of the spacing connecting rod 640 is hinged with fixed frame 41 and the other end is hinged with axletree 42.
So that axletree can do reciprocally swinging by radius of spacing connecting rod, but it can not be done relative to fixed frame along semi-trailer length
Direction relative motion, and then further evaded the problems such as axletree is disengaged or is broken with fixed frame, greatly improve rear overhang
Hang overall stability.
Rear horizontal valve 410 is additionally provided with the top surface of the fixed frame 41.So, by rear gasbag to Rear frame and
When the initial position of fixed frame is adjusted, can by rear horizontal valve convenient, straight tube judge rear car top of support whether water
It is flat.Also the initial position that Rear frame by the cooperation of rear horizontal valve and control system, can be automatically performed when its is actual use is set.
