An electric work vehicle of the present invention includes a left drive wheel and a right drive wheel that are supported to a vehicle body, a left motor that drives the left drive wheel and a right motor that drives the right drive wheel, a traveling motor control unit that controls the left motor and the right motor independently based on steering signals from a steering unit, and a turn response enhancement unit. The turn response enhancement unit gives, to the traveling motor control unit, additional control amounts for the left motor and the right motor so as to improve turning response during turning of the vehicle body.

A steering knuckle (18) is provided for use in association with a vehicle steering assembly (10). The steering knuckle (10) includes a knuckle body (20) having a generally vertical face (26) and an upper yolk arm (22) having a generally vertical face (54). The generally vertical faces (26, 54) of the steering knuckle body (20) and the upper yolk arm (22) are connected to each other. The generally vertical face (54) of the upper yolk arm (22) includes a camshaft bore (62) extending therethrough and configured to receive a camshaft (64). The generally vertical face of the knuckle body may be welded to a spindle (24), with a portion of the spindle being cut away to allow for a complete circular weld between the knuckle body and the spindle.

A ruler having an arch member on an upper surface of a ruler body for allowing the ruler body to closely contact a target object by being pressed from above. The ruler has a pair of parallel standing walls facing each other on the upper surface of the ruler body in a longitudinal direction, and the arch member is fitted along the longitudinal direction of the standing walls. In addition, bending pieces which bend inward towards each other are formed on upper end edges of the standing walls, projections which are positioned below the bending pieces project on both of outer side surfaces of the arch member, and the projections are guided by the bending pieces and are inserted between the standing walls.

Disclosed herein is a system of steering and suspension linkages for a beam-type solid axle arrangement, the steering system designed to operate in conjunction with the suspension system without bumpsteer throughout suspension travel. Accurate steering throughout suspension travel is satisfied with mechanical linkages that include a unique flexible joint-mounted bellcrank. The suspension system comprises two pairs of links, each pair occupying opposite sides of a solid axle, this opposed configuration offering the axle centering capability of without the packaging constraints of a triangulated 4-link suspension system, thereby facilitating its installation on production-based front solid axle vehicles.

When a collision load is transmitted to a gusset, the load is transmitted to an inner side in a vehicle width direction via an inclined wall. Accordingly, moment that causes a front side member to be projected and bent inward to the inner side in the vehicle width direction with an intersection being a starting point acts on the front side member. Then, the front side member, which has been projected and bent inward, collides with a power unit that is disposed in an engine compartment from an outer side in the vehicle width direction. Accordingly, a lateral force to the inner side in the vehicle width direction can be obtained for a vehicle.

A tractor mower with an enhanced turning radius comprising steerable left and right front wheels; left and right rear wheels; an engine for providing power to drive said rear wheels; an independent rear braking system capable of applying a braking force to said left and right rear wheels independently of one another; and a steering system coupled to said front steerable wheels and said independent rear braking system. The steering and braking systems may be configured such that when the tractor mower is steered in a first direction the front wheels are turned to the right and a braking force is applied on the right rear wheel. Alternatively, when the tractor mower is steered in a second direction the front wheels are turned to the left and a braking force is applied on the left rear wheel.

A riding yard maintenance vehicle may include a frame, a steering assembly, a cable and at least one set of guide pulleys. Wheels of the riding yard maintenance vehicle may be attachable to the frame. The steering assembly may include a steering apparatus operably coupled to front wheels of the riding yard maintenance vehicle via a cable system. The cable system may include the cable, which may be wrapped around at least a portion of the steering shaft. The cable may terminate at respective ends thereof at corresponding ones of a first shaped cam and a second shaped cam each of which is operably coupled to respective ones of a first axle rod and a second axle rod. The first and second axle rods may be rotatably connected to respective ones of the front wheels. The first and second shaped cams may cause movement of the front wheels based on movement of the cable responsive to rotation of the steering shaft. The at least one set of guide pulleys may receive respective different portions of the cable to guide the cable to respective ones of the first and second shaped cams.
