Referring to fig. 1 and 2, an embodiment of the present invention provides a suspension subframe, which is elastically connected to a main frame and elastically rotates relative to the main frame, compared to a rigid connection between a conventional frame and a chassis, and thus is called a suspension subframe. The subframe includes the following components: a support shaft 10, an elastic means and a support rod 30. Specifically, the support shaft 10 is rotatably connected to a main frame of the vehicle. The elastic device connects the support shaft 10 and the main frame, and elastically supports the support shaft 10 and the main frame. When the main frame of the automobile deforms in the left-right direction, the suspension type auxiliary frame rotates relative to the main frame through the supporting shaft 10, reaction force is transmitted to the elastic device between the suspension type auxiliary frame and the main frame, the elastic device has elastic force during compression and stretching, the suspension type auxiliary frame is guaranteed to be in a state close to the horizontal state, the stability of a load module of the automobile under uneven road conditions is achieved, and therefore the damage of an automobile supporting piece is avoided. Alternatively, in the suspension subframe of the present invention, the cross section of the support shaft 10 is circular, oval, square, diamond or other polygonal shape.
As shown in fig. 1 and 2, the suspension subframe is disposed on the main frame, and the load module of the vehicle is fixed to the suspension subframe. The support rod 30 is fixed on the support shaft 10, and the support rod 30 is matched with the support shaft 10 and used for supporting and fixing the load-carrying module. Alternatively, the number of the support rods 30 may be plural, and the support rods 30 are vertically arranged with respect to the support shaft 10.
In an embodiment of the present invention, as shown in fig. 1 and 2, the suspension subframe further includes: a first support seat 11 and a second support seat 12. Wherein, a first end of the supporting shaft 10 is disposed on the first supporting seat 11, and a second end of the supporting shaft 10 is disposed on the second supporting seat 12.
The main frame comprises a first bearing beam 41 and a second bearing beam 42 which are arranged in parallel, and the first bearing beam 41 and the second bearing beam 42 are used as main bearing parts of the main frame of the chassis.
Two ends of the first supporting seat 11 are respectively fixed on the first bearing beam 41 and the second bearing beam 42, and two ends of the second supporting seat 12 are respectively fixed on the first bearing beam 41 and the second bearing beam 42. Optionally, the first support seat 11 and the second support seat 12 are respectively perpendicular to the first bearing beam 41 and the second bearing beam 42. As shown in fig. 1 and 2, the support shaft 10 is optionally disposed parallel to the first bearing beam 41 and the second bearing beam 42, and is not located at the middle position between the first bearing beam 41 and the second bearing beam 42. Optionally, the first bearing beam 41 and the second bearing beam 42 are left and right longitudinal beams of the main frame, respectively.
Further, as shown in fig. 1, a first end of the supporting shaft 10 is rotatably connected to the first supporting seat 11 through a first pin 111, and a second end of the supporting shaft 10 is rotatably connected to the second supporting seat 12 through a second pin 121. The centers of the first pin shaft 111 and the second pin shaft 121 are on the same straight line, so that the support shaft 10 can rotate around the first pin shaft 111 and the second pin shaft 121, and rotation of the suspension type auxiliary frame relative to the main frame is achieved.
Further, in an embodiment of the present invention, as shown in fig. 1 and 2, the elastic device includes: a first elastic link 21 and a second elastic link 22 in a splayed shape.
