Embodiment
As shown in Figure 1, 2, resilient supporting unit described in the utility model, including it is arranged on gear box input and steering
Retainer 1 between framework frame, is bolted flexible support member between retainer 1 and gear-box；To mitigate retainer
Deadweight, the curved framed plate structure of retainer 1 of the present utility model set the upper/lower terminal of the inner arc plate of retainer 1 is horizontal-extending
It is equipped with symmetrical upper connecting base 2 and lower connecting base 3, the elasticity of upper connecting base 2 and lower connecting base 3 respectively by being installed on it
Component 4 is connected with gear box input；The reinforcement set in the inner arc back of retainer 1 by diverging（Reinforcement number
Amount is at least three, and diverging direction is dissipated from the groove of inner arc plate to convex side）Epipleural 5, transition are disposed with from top to bottom
Plate 6, lower side panel 7, epipleural 5 are parallel with the outer face of lower side panel 7, and connection corresponding with steering structure rack position is offered thereon
Hole；The upper vertical for connecting up seat 2 from the top of epipleural 5 is extended with upper junction plate 8, is connected downwards from the bottom of lower side panel 7
Seat lower section is extended the lower connecting plate 9 for having arcuate structure.
For ease of the connection of retainer 1 and gear-box, adjustment is provided with the faying face of upper connecting base 2 and elastic parts
Cushion block 10.
As shown in figure 3, elastic parts of the present utility model includes upper rubber base 4.1 and lower rubber base 4.2 and is fixed on
Block rubber 4.3 between upper and lower rubber base, to avoid coming off and overloading for block rubber during work, as shown in figure 5, in upper rubber
