Problems solved by technology
In order to achieve the purpose of dynamically adjusting the softness and hardness of the suspension according to the real-time driving state or the driver's intention, although the air spring in the prior art can do it, the air spring has a complicated structure and high cost compared with the coil spring
However, once the coil spring is manufactured, its hardness is determined and cannot be changed.

Embodiment Construction
[0014] Referring to the accompanying drawings, the structure and functions of the device will be described in detail below.
[0015] Such as Figure 1-3 As shown, the helical spring assembly 1 includes a helical spring and a helical body 3. The helical body 3 includes an elastic shell 3.1 and pressure oil 3.2 filled in a cavity in the shell. The helical body 3 is wound around two adjacent springs in the middle section of the helical spring. Between the wire 2, the two ends in the width direction are fixedly adhered to the spring wire, the width of the helix is approximately equal to the pitch of the helical spring, and the thickness is approximately equal to the diameter of the reed wire of the helical spring;
[0016] One end of the elastic shell 3.1 in the length direction has an oil inlet 4 and the other end has an oil outlet 5. The oil inlet 4 and the oil outlet 5 are connected to the pressure oil container 6 to form a pressure oil circulation circuit. The pressure oil c...

The invention discloses an electric vehicle suspension with hardness being adjustable. The electric vehicle suspension with the hardness being adjustable comprises a damping shock absorber and a spring assembly; the spring assembly comprises a spiral spring and a spirochete, the spirochete comprises an elastic shell and pressure oil, a cavity in the shell is filled with the pressure oil, the hardness of the spring assembly can be dynamically adjusted according to operation information of a driver and driving state information, so that the hardness degree of the electric vehicle suspension can accord with the requirements for driving better, the driving experience is optimized, the electric vehicle suspension with the hardness being adjustable is simple in structure, and can be achieved by directly and additionally being installed on the basis of an conventional damper spring, and the cost is reduced.
Description
technical field [0001] The present application relates to the field of vehicle suspension, in particular to a suspension for an electric vehicle and a coil spring assembly for the suspension. Background technique [0002] The elements that affect the operational stability and comfort of the vehicle suspension include elastic elements and damping elements, and coil springs are commonly used elastic elements. In order to achieve the purpose of dynamically adjusting the softness and hardness of the suspension according to the real-time driving state or the driver's intention, although the air spring in the prior art can do it, the air spring has a complicated structure and high cost compared with the coil spring . However, once the coil spring is manufactured, its hardness is determined to be irreversible. Therefore, the purpose of this solution is to provide a helical spring that can dynamically adjust the degree of softness and hardness. Contents of the invention [0003...
