Embodiments of the present utility model will be described in detail below, by way of example with reference to the accompanying drawings.

A suspension 1 according to an embodiment of the utility model is described below with reference to fig. 1-7. The suspension 1 is typically arranged on a vehicle, mainly for maintaining the vehicle relatively stable, so that the vehicle may operate more smoothly.

The suspension 1 of the vehicle according to the embodiment of the present utility model includes a suspension bracket 10, a bushing assembly 20, an inner core 30, and a shock absorber 40. Wherein, suspension support 10 mainly plays the effect of installation and support, and bushing assembly 20 mainly plays the effect of installation, and inner core 30 mainly plays the effect of installation and support, and shock absorber 40 can play damping or spacing effect according to the actual operating mode.

As shown in fig. 1 and 2, the suspension bracket 10 is provided with a powertrain mounting portion 11 and a mounting bracket 12. Wherein, the power assembly installation part 11 and the installation bracket 12 mainly play a role in installation, and the power assembly installation part 11 can be connected with a power assembly. The power assembly mounting part 11 is arranged on the suspension bracket 10, so that the suspension bracket 10 can be connected with the power assembly through the power assembly mounting part 11, the connection between the suspension bracket 10 and the power assembly can be more stable, and the vehicle can work better.

As shown in fig. 1 and 2, a bushing assembly 20 is provided on the suspension bracket 10. The bushing assembly 20 is arranged on the suspension bracket 10, so that the bushing assembly 20 can be fixed, the arrangement of the bushing assembly 20 is firmer and more stable, and the bushing assembly 20 can be matched with the suspension bracket 10 better.

As shown in fig. 1 and 2, the inner core 30 is connected to the bushing assembly 20, and the inner core 30 is provided with a subframe mounting portion 31. The subframe mounting portion 31 also mainly plays a role of mounting, and the subframe mounting portion 31 can be connected to the subframe. The sub-frame mounting portion 31 is provided on the inner core 30, so that the inner core 30 can be connected with the sub-frame through the sub-frame mounting portion 31, and the connection of the inner core 30 with the sub-frame can be made more stable. The inner core 30 is connected with the bushing assembly 20, so that the inner core 30 can be fixed, the inner core 30 is more firmly and stably arranged, the inner core 30 is more stably connected with the auxiliary frame, and the auxiliary frame can work better.

Specifically, when the powertrain generates torque to be transmitted to the suspension bracket 10, the suspension bracket 10 transmits the torque to the bushing assembly 20, and the bushing assembly 20 has a function of converting the power torque to force, so that the bushing assembly 20 transmits the force to the sub-frame. Since the subframe is connected to the bushing assembly 20 by the inner core 30, the subframe can exert a reverse force on the bushing assembly 20, thereby providing a torsional effect to the suspension bracket 10.

As shown in fig. 1 and 2, the vibration absorber 40 is disposed on the mounting bracket 12, so that the vibration absorber 40 can be fixed, so that the vibration absorber 40 can be better matched with the mounting bracket 12, that is, the vibration on the mounting bracket 12 can be better absorbed, or the mounting bracket 12 can be better limited.

From this, through set up bush subassembly 20 and inner core 30 on suspension support 10, inner core 30 is connected with the sub vehicle frame again, and like this when the power assembly will torsion transmission for suspension support 10, the sub vehicle frame can produce reverse effort to bush subassembly 20 and inner core 30 to can promote suspension support 10's torsional properties, and then can promote suspension support 10's vibration isolation performance, extension suspension support 10's life-span makes the vehicle can more stable work.

Further, as shown in fig. 3, the bushing assembly 20 includes: the first outer tube 21, the first spacing rib 22 and the first stopper 23, the first outer tube 21 sets up on suspension support 10, and first spacing rib 22 and first stopper 23 set up respectively on the inner wall of first outer tube 21, and first spacing rib 22 is connected with inner core 30, and first stopper 23 and inner core 30 interval set up. Wherein, first outer tube 21 mainly plays the effect of connection and support, and first spacing muscle 22 and first stopper 23 all can play the effect of damping buffering. The first outer tube 21 is provided on the suspension bracket 10 so that the first outer tube 21 can be fixed, thereby making the provision of the first outer tube 21 more secure and stable. The first limiting ribs 22 and the first limiting blocks 23 are respectively arranged on the inner wall of the first outer tube 21, so that the arrangement is more reasonable, and the first limiting ribs 22 and the first limiting blocks 23 are matched with the inner core 30 conveniently. And can fix first spacing muscle 22 and first stopper 23, make the setting of first spacing muscle 22 and first stopper 23 more firm and stable.

The first spacing rib 22 is connected with the inner core 30, so that the connection between the first spacing rib 22 and the inner core 30 is more stable. Specifically, when the power assembly transmits torque and vibration to the first outer tube 21 through the suspension bracket 10, the first outer tube 21 has a torsion tendency and an inward movement deformation tendency, and since the first stopper rib 22 is connected between the first outer tube 21 and the inner core 30, the first stopper rib 22 can restrict and absorb the vibration and deformation amount of the first outer tube 21, so that the inner core 30 can be maintained relatively stable, and thus the subframe can be maintained relatively stable, and the vehicle can operate more stably. The first limiting block 23 is spaced from the inner core 30, that is, a gap is formed between the first limiting block 23 and the inner core 30. When the deformation of the first outer tube 21 is too large, the first limiting rib 22 is insufficient to absorb and buffer the deformation of the first outer tube 21, and at this time, the first limiting block 23 contacts the inner core 30 under the deformation pressure of the first outer tube 21, so as to compensate the first limiting rib 22 and limit the deformation of the first outer tube 21.

The vibration absorber 40 in this embodiment mainly plays a role of absorbing vibration. The vibration absorber 40 is arranged on the mounting bracket 12, so that the arrangement is more reasonable, and the vibration absorber 40 can absorb vibration energy on the mounting bracket 12 conveniently while the vibration absorber 40 is fixed. Specifically, when the powertrain transmits vibrations to the suspension mount 10, the vibration absorber 40 can absorb vibrations on the suspension mount 10, so that the suspension mount 10 can be kept relatively stable, and thus the subframe can be kept relatively stable. When the excitation frequency of the powertrain is coupled with the modal frequency of the peripheral accessory, resonance is generated, vibration can be transmitted to the subframe through the suspension bracket 10, the bushing assembly 20 and the inner core 30, and then to the vehicle body, and the vibration absorber 40 can balance the excitation force induced by the powertrain, so that the influence caused by resonance can be reduced.

Specifically, as shown in fig. 1 and 3, the cross-sectional shape of the core 30 is configured in a circular ring shape in the up-down direction of the vehicle. That is, in the up-down direction of the vehicle, the inner core 30 is an annular structural member, so that the arrangement is more reasonable, and the inner core 30 and the auxiliary frame are convenient to be mounted and matched. Meanwhile, the circular ring-shaped structure is simple, and the inner core 30 is convenient to process and set.

As an alternative embodiment, as shown in fig. 2 and 4, the bushing assembly 20 includes: the second outer tube 24, the second spacing muscle 25, second stopper 26 and steel bushing 27, second outer tube 24 sets up on suspension support 10, second spacing muscle 25 and second stopper 26 set up respectively on the inner wall of second outer tube 24, steel bushing 27 sets up in the inboard of second outer tube 24, second spacing muscle 25 is connected with steel bushing 27, second stopper 26 and steel bushing 27 interval setting, steel bushing 27 is connected with inner core 30.

Wherein, the second outer tube 24 mainly plays the effect of connection and support, and second spacing muscle 25 and second stopper 26 all can play the effect of damping buffering, and steel bushing 27 mainly plays the effect of installation and support. The second outer tube 24 is disposed on the suspension bracket 10, so that the second outer tube 24 can be fixed, and the second outer tube 24 can be disposed more firmly and stably. The second limiting ribs 25 and the second limiting blocks 26 are respectively arranged on the inner wall of the second outer pipe 24, so that the arrangement is more reasonable, and the second limiting ribs 25 and the second limiting blocks 26 are matched with the steel sleeve 27 conveniently. And can fix second spacing muscle 25 and second stopper 26, make second spacing muscle 25 and second stopper 26 can work better.

The steel sleeve 27 is connected with the inner core 30, so that the connection between the steel sleeve 27 and the inner core 30 is more stable, and the arrangement of the steel sleeve 27 is convenient for the inner core 30 to be matched with the second limiting rib 25. Specifically, when the power assembly transmits torque and vibration to the second outer tube 24 through the suspension bracket 10, the second outer tube 24 has a tendency to twist and deform inwardly, and since the second stopper rib 25 is connected between the second outer tube 24 and the steel bushing 27, the second stopper rib 25 can restrict and absorb the amount of twist and deformation of the second outer tube 24, so that the steel bushing 27 and the inner core 30 can be maintained relatively stable, and thus the suspension bracket 10 can be maintained relatively stable, the torsion resistance of the suspension bracket 10 can be improved, and the vehicle can operate more stably. And the resonance condition of the vehicle caused by high-frequency vibration of the power assembly can be improved to a certain extent.

The second limiting block 26 is arranged at intervals with the steel sleeve 27, that is to say, a gap is reserved between the second limiting block 26 and the steel sleeve 27. When the deformation of the second outer tube 24 is too large, the second limiting rib 25 is insufficient to absorb and buffer the deformation of the second outer tube 24, and the second limiting block 26 contacts the steel sleeve 27 under the deformation pressure of the second outer tube 24, so that the second limiting rib 25 can be compensated, and the deformation of the second outer tube 24 is reduced.

It should be noted that, the vibration absorber 40 in this embodiment mainly plays a role of limiting, and the vibration absorber 40 is disposed on the mounting bracket 12, so that the vibration absorber 40 can limit the mounting bracket 12 while fixing the vibration absorber 40, thereby maintaining the relative stability of the suspension bracket 10 and improving the torsion resistance of the suspension bracket 10. Specifically, when the powertrain transmits torque to the suspension mount 10, the shock absorber 40 can limit the mounting mount 12, and maintain the relative stability of the mounting mount 12, so that the torsional performance of the suspension mount 10 can be further improved, the relative stability of the suspension mount 10 can be maintained, and the subframe can be further maintained relatively stable.
