Problems solved by technology
[0002] When the test bench of the engine powertrain is doing the bench test, the axle needs to be replaced by an adapter and connected to the dynamometer, and the hub is subjected to multi-dimensional forces. The existing technical solutions do not consider or do not fully consider this, and the adapter will appear. Damage due to friction and vibration shock, loss of torque transmission due to adapter frictional resistance, etc.

The invention relates to the technical field of vehicles, and discloses a vehicle axle hub adapter and an experimental bench of a power assembly. The vehicle axle hub adapter comprises a lifting bracket configured to be able to adjust height in a vertical direction; an adapter body positioned above the lifting bracket, wherein the adapter body comprises a fixed bracket and a connecting component,the connecting component is fixed on the fixed bracket in a hanging mode, universal ball components are arranged at the lower end of the bracket and configured to be able to roll in any direction; anda shock-absorbing seat fixedly connected to a top end of the lifting bracket. The lifting bracket of the vehicle axle hub adapter disclosed by the invention can adjust the height of the adapter body,the shock-absorbing seat can reduce the probability that the adapter body is damaged due to vibration shock, the torque can be output efficiently through the universal ball components and the shock-absorbing seat, and the connecting component can enable the adapter body to have a certain angular displacement when bearing acting force, thereby preventing the adapter body from being damaged.
Description
technical field [0001] The invention relates to the technical field of a test bench for a power assembly, in particular to an axle hub adapter and a test bench for a power assembly. Background technique [0002] When the test bench of the engine powertrain is doing the bench test, the axle needs to be replaced by an adapter and connected to the dynamometer, and the hub is subjected to multi-dimensional forces. The existing technical solutions do not consider or do not fully consider this, and the adapter will appear. Damage due to friction and vibration shock, loss of torque transmission due to adapter frictional resistance, etc. Contents of the invention [0003] Based on the above, the object of the present invention is to provide a test bench for an axle hub adapter and a powertrain, wherein the axle hub adapter disclosed in the present invention can reduce the risk of damage to the adapter body due to friction and vibration shocks. probability, and can also reduce the...
