TH44012A - Steering mechanism of a three-wheeled truck. - Google Patents

Abstract

DC60 (22/10/42) The steering mechanism using a rocking action on the cargo bed, as described in this invention, is used in three-wheeled vehicles for general cargo transport. It is engine-driven, with the rear wheels receiving power from the engine or powered by human pedaling. There are two front wheels for turning, and one or two rear wheels positioned closely together. Steering control is achieved by a vertical axle that rotates with the rotation of the cargo bed. A control arm acts as the torque regulator for the vertical axle and controls the steering direction through variable rotation of the steering lever. It is used as a mechanism to control the direction and turning of the vehicle, based on the varying range of rotation of the steering wheel.

Claims (1)

1. The steering mechanism of a typical 3-wheel truck consists of two front wheels spaced apart and one rear wheel, or two rear wheels spaced apart and one rear wheel, or two rear wheels that are close together or spaced apart, with the cargo bed at the front of the vehicle. Steering is controlled by rocking the cargo bed (2) to the left or right, with the vertical shaft (3) as the pivot point. The top of the shaft has a flange (1) bolted to the flange 1A of the cargo bed (2), and the bottom of the shaft (3) is attached to the control arm (5). The pulling force of the control arm is transmitted through the tie rod (6) to control the wheel axle assembly (7), which has the front wheel pin (9) as the pivot point, allowing the wheels to turn back and forth according to the varying range of the rocking of the control lever (8) on the cargo bed to control the turning direction.
