Problems solved by technology
[0003] The existing electric vehicle motor rear suspension usually includes an elastic body connected to the sub-frame and a suspension bracket fixed on the elastic body for connection with the motor. The suspension bracket is usually an integral plate, which The suspension bracket of this structural form has effective strength and is prone to breakage during work, resulting in reduced reliability of the motor. At the same time, the rigidity of this plate is low, and resonance is prone to occur when the motor is running, resulting in greater noise when the motor is running. Reduced driving comfort

The invention discloses a rear suspension assembly for an electric vehicle power system. The assembly comprises an inner sleeve connected with a rack, an outer sleeve sleeving the inner sleeve, elastic filler filling the gap between the inner sleeve and the outer sleeve and a suspension support which is fixed on the outer sleeve and is used for connecting a motor, wherein the suspension rack comprises a plurality supporting plates which are fixed one another, and are provided with arc supporting openings which are matched with outer circle of the outer sleeve for supporting the outer sleeve. The suspension assembly has high integrity and high rigidity, can be used for effectively avoiding breakage of the suspension rack, and is beneficial to reducing the integral noise of a motor, so that the comfortable feeling and reliability of the whole vehicle can be improved.
Description
technical field [0001] The invention belongs to the field of electric vehicle components, and in particular relates to a rear suspension assembly of an electric vehicle power system. Background technique [0002] With the rapid development of automobile products, automobile manufacturers are accelerating the development of complete vehicle products in the constant competition. The matching of the motor of electric vehicles and the layout of the subframe of the complete vehicle is particularly critical. The motor itself is an internal vibration source, and it is also disturbed by various vibrations from the outside. Cause damage to parts and uncomfortable riding. Therefore, design the suspension system to minimize the vibration transmitted from the motor to the support system. Successful vibration control depends on the structural form, geometric position of the suspension system, and the structure, stiffness and damping characteristics of the suspension cushion. . It has ...
