II composition, the convex pad of circle are fixed on the auxiliary spring end of the leaf spring by buckle II；If it is provided with the convex pad
Dry circular protrusions.
Further, the mounting bracket includes assistant support, longitudinal support and lateral frame, and longitudinal support is set with lateral frame in 90 degree
Put, be respectively welded on the assistant support, the assistant support is used to connect the secondary buffer stopper.
The beneficial effects of the utility model are first, and three leaf spring variable cross-section progressive rate structures, stress is smaller, light
Its service life is improved while quantization, the suspension progressive rate form is advantageous to the comfortableness of vehicle.Second, in three leaf springs
Between mat and both ends noise abatement pad, add the friction between reed, reduce noise, improve leaf spring service life.3rd,
Using major-minor buffer block structure form, double buffering block structure form effectively increases the impact during Suspension movement, has
Good impact absorbing ability, secondary buffer stopper can more use as secondary spring, be advantageous to the control of rigid axle suspension vehicle attitude.

Embodiment
Specific embodiment of the present utility model is described below in detail, the embodiment described by reference to accompanying drawing is exemplary
, it is only used for explaining the utility model, and can not be construed to limitation of the present utility model.
As Figure 1-3, the back suspension device includes leaf spring 1, drive axle 7, and mounting bracket 4 is consolidated by bolt assembly
It is scheduled on vehicle body 3.Secondary cushion pad 6 is provided with drive axle 7.Secondary one end of buffer stopper 5 is arranged in mounting bracket 4, the other end and institute
Secondary cushion pad 6 is stated to contact.Host buffer assembly 2 is arranged on drive axle 7 by U-bolts 6.The spring of steel plate bullet 1 is fixedly mounted
On the drive axle 7, the leaf spring is arranged for longitudinal, is made up of three leaf springs, wherein preceding two panels is main spring, it is rear a piece of
For auxiliary spring, auxiliary spring uses variable section structure, and thickness successively decreases at center hole to both ends.
Using thick middle both ends, gradually thin shape, three leaf springs belong to progressive rate formula form, can pass through main steel plate
Contact of the spring with overload spring obtains nonlinear characteristic, can avoid being suspended in motion loading process because of the mutation of rigidity
And causing leaf spring phenomenon of rupture, stress is smaller, and light-weighted while improve its service life, the suspension progressive rate form has
Beneficial to the comfortableness of vehicle.
As shown in figure 4, backing plate 11 is set respectively between the main spring of two panels, between second main spring and auxiliary spring.The backing plate 11
It is made up of nonmetallic materials, the friction between reed is added while gap between ensuring reed, reduces noise.
As shown in figure 5, be respectively arranged with noise abatement pad 9 at described 1 second main spring both ends of leaf spring, the noise abatement pad 9 by
Noise abatement backing plate 12 and buckle I 13 form, and the noise abatement pad 9 is fixed on second main spring of the leaf spring by buckle I 13
End.As shown in fig. 6, being respectively arranged with circular convex pad 10 at the auxiliary spring both ends of leaf spring 1, the noise abatement pad 10 is by convex pad 14
Formed with buckle II 15, the convex pad 10 of circle is fixed on the auxiliary spring end of the leaf spring 1 by buckle II 15；It is described convex
Several circular protrusions 16 are provided with pad 14.These structure types can more reduce noise between plate, improve leaf spring service life.
As shown in fig. 7, the mounting bracket 4 includes assistant support 17, longitudinal support 18 and lateral frame 19, longitudinal support 18 and horizontal branch
Frame 19 is respectively welded on the assistant support 17, the assistant support 17 is used to connect the secondary buffer stopper 5 in 90 degree of settings.Suspension
In upper jump process, when above jumping to certain stroke, secondary the buffer stopper pad 6 and secondary buffer stopper 5 that are welded on drive axle 7 contact,
After secondary buffer stopper 5 is compressed to certain stroke, host buffer assembly 2 and lateral frame 19 contact, and at this moment major-minor buffering works together, until
It is compressed to limiting condition.By the distribution of power in major-minor buffer stopper compression process, rear spring can be alleviated and be suspended in certain point power
Mutation, double buffering block structure form effectively increases the impact during Suspension movement, the impact absorbing ability having had,
Secondary buffer stopper can more use as secondary spring, be advantageous to the control of rigid axle suspension vehicle attitude.
Construction, feature and effect effect of the present utility model is described in detail according to embodiment shown in the drawings above
Fruit, preferable embodiment of the present utility model is the foregoing is only, but the utility model is not protected to limit its shown in drawing
