DEFINITION

Classification: 280/124.166

Torsion spring:

(under subclass 124.164) Subject matter wherein the mechanical spring element has a lengthwise axis and undergoes a twisting deformation (torque deformation) about its lengthwise axis in response to an applied force.

SEE OR SEARCH THIS CLASS, SUBCLASS:

5.511, for an active suspension responsive while the vehicle is in surface traversing motion wherein a sway or torsion bar is regulated.

86.5, for an auxiliary axle assembly which may or may not include a torsion spring.

104+, for vehicle running gear including an equalized frame, especially subclasses 679 or 684 for tandem axles including torsion spring means.

124.103, for a suspension arrangement causing body banking on turning which may or may not include a torsion spring.

124.107, for a suspension arrangement preventing body roll which may or may not include a torsion spring.

124.116, for a suspension arrangement wherein an axle or axle assembly is mounted upon a horizontal and transverse pivot axis which may or may not include a torsion spring. 124.125+, for a suspension arrangement for separately supporting a wheel upon an individual skein or spindle axle, especially subclasses 124.13, 124.137, 124.149, or 124.152 which include a torsion spring device.
