Abstract
A tag axle system for a concrete mixing vehicle including an axle including a right wheel assembly and a left wheel assembly, an actuator coupled to the axle to move the axle between a raised position and a lowered position relative to a vehicle chassis, a stabilizer mount plate structured to be coupled to the vehicle chassis, a stabilizer bar rotationally coupled to the stabilizer mount plate, a right stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the right wheel assembly, and a left stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the left wheel assembly.
Claims15
A tag axle system, comprising:
- an axle including a right wheel assembly and a left wheel assembly;
- an actuator coupled to the axle to move the axle between a raised position and a lowered position relative to a vehicle chassis;
- a stabilizer mount plate structured to be coupled to the vehicle chassis;
- a stabilizer bar rotationally coupled to the stabilizer mount plate;
- a right stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the right wheel assembly;
- a left stabilizer bar arm rigidly coupled to the stabilizer bar and coupled to the left wheel assembly;
- and
- a spacer block coupled between the stabilizer mount plate and the stabilizer bar to increase a distance between the stabilizer bar and the vehicle chassis.
An auxiliary suspension for a heavy vehicle comprising:
- an axle including a right axle stabilizer mount and a left axle stabilizer mount;
- an actuator coupled to the axle to move the axle between a raised position and a lowered position relative to a vehicle chassis, the actuator structured to act as a suspension;
- a stabilizer bar rotationally coupled to the vehicle chassis;
- a right stabilizer bar arm rigidly coupled between the stabilizer bar and the right axle stabilizer mount;
- a left stabilizer bar arm rigidly coupled between the stabilizer bar and the left axle stabilizer mount;
- a stabilizer mount plate structured to be coupled to the vehicle chassis and to support the stabilizer bar;
- and
- a spacer block coupled between the stabilizer mount plate and the stabilizer bar to increase a distance between the stabilizer bar and the vehicle chassis.
A stabilizer bar system for a load span tag axle, the stabilizer bar system comprising:
- an axle beam;
- a four-bar linkage coupling the axle beam to a vehicle chassis;
- an actuator coupled between the axle beam and the vehicle chassis and structured to actuate the axle beam between a raised position and a lowered position, and to act as a suspension;
- a stabilizer bar coupled between the vehicle chassis and the axle beam and structured to increase roll stiffness of the four-bar linkage and actuator when used as a suspension;
- a stabilizer mount plate structured to be coupled to the vehicle chassis and to support the stabilizer bar;
- and
- a spacer block coupled between the stabilizer mount plate and the stabilizer bar to increase a distance between the stabilizer bar and the vehicle chassis.
