Description
Technical Field
The utility model relates to a suspension damping device for a tracked vehicle, and belongs to the technical field of tracked vehicles.
Background
When the tracked vehicle runs on a road and in an area with uneven road pits, the thrust wheels and the vehicle body of the vehicle suspension device can generate vibration, and the vibration can affect the service performance of the vehicle, namely the running stability, traction characteristic, stability and operability, and the strength and service life of each part.
For example, in chinese patent publication No. CN213974219U, a multi-swing-arm multi-suspension type crawler traveling mechanism is disclosed in the following technology: the middle parts of the two swing arms are rotatably arranged on the intermediate shaft, and the inner ends of the intermediate shaft extending out of the swing arms are fixed on the frame; the lower ends of the two swing arms are fixedly connected through a lower end shaft, and the lower end shaft is non-rotatable on the swing arms; the support frame is in between two swing arms and the support frame is close to the swing arm setting, and the top of each support frame rotationally installs at the lower extreme epaxially, and fixed mounting has a heavy burden shaft between the lower extreme of two support frames, and a plurality of bogie wheels are rotationally installed to the heavy burden shaft, and the bogie wheel is used for exerting pressure to the track. When the track produces vibrations and transmits to the bogie wheel on, the vibration of bogie wheel can transmit the automobile body again on the jackshaft through the support frame, because only the inner of jackshaft is fixed in on the frame, has the jackshaft to bear the relatively weak problem of impact capacity that vibrations produced, can't satisfy heavy-duty tracked vehicle's cross-country shock attenuation demand.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a suspension damping device for a tracked vehicle.
The utility model is realized by the following technical scheme.
The utility model provides a suspension damping device for a tracked vehicle, comprising:
a fixed support;
the supporting seat and the fixed support are spaced;
the elastic metal rod is arranged, one end of the metal rod is in non-rotatable fit connection with the fixed support, and the other end of the metal rod can rotate on the supporting seat and extend out, so that the metal rod can obtain a supporting point on the supporting seat and can rotate;
the end part of the metal rod extending out of the supporting seat is in non-rotatable fit connection with one end of the swing arm, and the swing arm can drive the metal rod to elastically rotate and twist around the axis of the metal rod;
the other end of the swing arm is in non-rotatable fit connection with the thrust wheel, and the weight load of the thrust wheel drives the swing arm to rotate so that the metal rod generates torque to obtain elastic force to support the vehicle body.
The metal rod is connected with a spline groove arranged on the fixed support in a matching way through a spline.
The metal rod can rotatably penetrate through the through hole formed in the supporting seat and extend out of the through hole.
The end part of the metal rod extending out of the supporting seat is connected with a spline arranged at one end of the swing arm in a matching way through the spline.
