During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the application.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the application.
As shown in figure 1, the dependent rear suspension of the application is arranged between axle assembly 1 and vehicle frame (not shown),
The dependent rear suspension includes main assemblage of spring 2, thrust device assembly 3 and vibration damper assembly 4, one end of the main assemblage of spring 2
The vehicle frame is connected to, the other end is connected to the axle assembly 1.Not level road is buffered by main assemblage of spring 2 in vehicle travel process
Vibration and impact that face is brought, to improve riding comfort and automobile ride.Described one end of thrust device assembly 3 is connected to
The other end of axle assembly 1 is connected to the vehicle frame, and the thrust device assembly 3 is engaged with the main assemblage of spring 2, improves
The control stability of vehicle.Described one end of vibration damper assembly 4 is connected to the other end of axle assembly 1 and is connected to the vehicle frame,
Spring in main assemblage of spring 2 is that the flexible member of main assemblage of spring 2 in helical spring 21, the dependent rear suspension uses spiral bullet
Spring 21, compared with using the air rear suspension structure of air spring, eliminates control system assembly, improves workshop efficiency of assembling,
Reduce the production cost of vehicle.After the impact from uneven road surface make it that helical spring 21 compresses, vibration damper assembly 4 can press down
Concussion when being rebounded after the shock-absorbing of helical spring 21 processed, improves the ride performance of vehicle.
As shown in Figure 2 and Figure 3, the main assemblage of spring 2 also includes being connected to the first mounting bracket 22 of the vehicle frame and is connected to
First pallet 23 of the axle assembly 1, the other end of first mounting bracket 22 is connected with the second pallet 24, the spiral bullet
Spring 21 is arranged in the space of the pallet 24 of the first pallet 23 and second formation.Because helical spring 21 is hollow structure, need
To be supported and be positioned by the first pallet 23 and the second pallet 24, specifically：
The positioning of helical spring 21：
Second pallet 24 is provided with buffer stopper 241, and the buffer stopper 241 is centrally located at the axle of the helical spring 21
On line, so that the equably impact on the axis direction of damping coil spring 21, second pallet 24 and first mounting bracket
22 are fixedly connected by locking member 242.The locking member 242 can for bolt or other can be fixedly connected with the first mounting bracket
22 and second pallet 24 structure, such as welding, the application is not limited this, between the first mounting bracket 22 and vehicle frame
To be fixedly connected, it is fixedly connected between the second pallet 24 and the first mounting bracket 22, so as to enter to the axial float of helical spring 21
Upper limit is gone.
Further, the first stopper 243 and the second stopper 244, described first are additionally provided with second pallet 24
Stopper 243 constitutes the host cavity 245 for housing the body of helical spring 21 with second stopper 244.That is, described first
Outside and inner side of the stopper 243 with second stopper 244 respectively with the helical spring 21 are abutted against, so as to spiral
The radial-play progress of spring 21 is spacing, prevents that helical spring 21 is tilted in compression process, influences vehicle security energy.
It is fixedly connected between first pallet 23 and axle assembly 1, so as to be carried out to the axial float of helical spring 21
Lower limit, by the collective effect of the first pallet 23 and the second pallet 24, axle assembly 1 and first is limited in by helical spring 21
Between mounting bracket 22.
The end face of first pallet 23 upwardly extends to form the 3rd stopper 231, the 3rd stopper 231 with it is described
Helical spring 21 is abutted against.That is, the described 3rd stops that fast 231 internal diameter adapts to the external diameter of the helical spring 21.The application
In the first stopper 243, the second stopper 244 and the 3rd stopper 231 collective effect come spacing helical spring 21 footpath
To play, the collective effect of the first pallet 23 and the second pallet 24 carrys out the axial float of spacing helical spring 21, so that, in the external world
The compression and tension of helical spring 21 is carried out along the direction that it is pre-seted under percussion.
The buffering of helical spring 21 with it is spacing：
The limited block 232 corresponding with the buffer stopper 241, the axle assembly 1 are additionally provided with first pallet 23
It is connected with first pallet 23 by the mounting hole 234 being arranged on the limited block 233.It is provided with the mounting hole 234
Screw thread, is bolted to connection between the first pallet 23 and axle assembly 1, due to the first pallet being connected with axle assembly 1
23 and the limited block 232 that is arranged on first pallet 23 be main load part, so, prolong on first pallet 23
Stretching has the reinforcement 233 for being connected to the limited block 232, improves intensity.
After pavement roughness is impacted to axle assembly 1, the impact can be transferred to the first pallet 23 via vehicle bridge to be made
Obtain helical spring 21 to compress, the motion upwards therewith of limited block 232, lasting impact causes limited block 232 to move upwards and with delaying
Rush block 241 to hit, it is rubber that buffer stopper 241, which has the part contacted with the limited block 232, in the application, so that knockout process
In buffer stopper 241 can produce certain elastic compression, to be rigidly connected between the second pallet 24 and vehicle frame, when buffer stopper 241
When being compressed to the limit, helical spring 21 is not recompressed, and the height that reaches capacity is altered on axle assembly 1, and in helical spring 21
Poor in order to avoid compressing the too fast comfortableness for causing vehicle in compression process, the vibration damper assembly 4 in the application provides damping,
Helical spring 21 is slowly compressed at the appropriate speed, and after impact disappears, when helical spring 21 needs stretching, damper
Assembly 4 still provides damping, it is to avoid altered under axle assembly 1 too fast.It should be noted that first, buffer stopper 241 and limited block
Whether 232 can occur to hit in the impact size and duration depending on the external world, this specification with its generation shock and buffer stopper
241 are compressed to exemplified by the limit and illustrate, secondly, the distance between the bottom of buffer stopper 241 and top of limited block 232, need
Reasonable computation is carried out according to the different of the rigidity of helical spring 21 of use.
In order to preferably realize the buffering effect and compression performance of buffer stopper 241, set in the circumference of the buffer stopper 241
There is groove 246 at least one, the bottom up of the buffer stopper 241 is provided with depressed part 247, and the interior of depressed part 247 is provided with
Annular groove 248.
The overall structure of the application rigid axle suspension：
The axle assembly 1 includes the assembly fixture 12 of two C-arms 11 and connection two C-arms 11, described
The end of a piece C-arm 11 is provided with locking hole (not shown), and the main assemblage of spring 2 and vibration damper assembly 4 are by being arranged on
Fastener in the locking hole is fixedly connected with axle assembly 1.In order to which firmly multiple, the application can be set by connecting locking hole
In the quantity and arrangement mode of locking hole are not limited, also, be provided with screw thread in the locking hole, thus main assemblage of spring 2 with
Vibration damper assembly 4 is bolted to connection in C-arm 11, and it is total to be equipped with spring at the two ends of any C-arm 11
Into 2 and the vibration damper assembly 4.
The thrust device assembly 3 includes the first distance rod 31, the second distance rod 32 and is fixedly connected with the vehicle frame
The second mounting bracket 33, the two ends of first distance rod 31 are connected to second mounting bracket 33 and C-arm 11, described
