摘要

In certain embodiments of the invention, devices for locking a spring assembly on a tandem-axle vehicle are provided. Some embodiments relate to methods of locking a spring assembly on a tandem-axle vehicle. In some embodiments, devices for locking a spring assembly on a tandem-axle vehicle, such devices comprising: a block having a top surface, a bottom surface, and a plurality of side surfaces between the top surface and the bottom surface, wherein the top surface may or may not be parallel to the bottom surface, wherein the distance between the top surface and the bottom surface is between about 2 and about 25 cm, and wherein the top surface is angled between 5 and 45 degrees with respect to the bottom surface; wherein the block is adapted to be inserted between a first leaf spring and a frame of a vehicle to lock the vehicle's spring assembly.

主权项

1. A method of locking a spring assembly on a tandem-axle vehicle having a first spring hanger disposed on a vehicle frame; a first leaf spring operably connected to a first axle, wherein one end of the first leaf spring is operably connected to the first spring hanger via a first equalizer; and a second leaf spring operably connected to a second axle, wherein one end of the second leaf spring is operably connected to the first spring hanger via a second equalizer, the method comprising:
inserting a device between the first leaf spring and the frame, wherein the device comprises a block having a top surface, a bottom surface, and a plurality of side surfaces between the top surface and the bottom surface, wherein the top surface is substantially parallel to the bottom surface, and wherein the distance between the top surface and the bottom surface is between about 2 and about 25 centimeters, and the device is inserted such that the top surface of the block contacts the frame and the bottom surface of the block contacts the first leaf spring.
