Abstract:
A skid steer vehicle, comprising:(A) a chassis having a left side and a right side; (B) an engine fixed to the chassis; (C) a first hydraulic fluid pump driven by the engine to provide hydraulic fluid under pressure; (D) a second hydraulic fluid pump driven by the engine to provide hydraulic fluid under pressure; (E) at least a first hydraulic motor in fluid communication with the first hydraulic fluid pump; (F) at least a second hydraulic motor in fluid communication with the second hydraulic fluid pump; and (G) left front and left rear suspensions mounted in a fore-and-aft arrangement on the left side of the chassis for pivotal movement with respect thereto, each left suspension including: (1) a left ground-engaging wheel extending from the left side of the chassis and rotationally coupled to the at least a first hydraulic motor to be driven in rotation thereby, (2) a left control arm assembly coupled to and between the left wheel and the chassis to pivot with respect to the chassis about a left control arm pivotal axis; and (H) right front and right rear suspensions mounted in a fore-and-aft arrangement on the right side of the chassis for pivotal movement with respect thereto, each right suspension including: (1) a right ground-engaging wheel extending from the right side of the chassis and rotationally coupled to the at least a second hydraulic motor to be driven in rotation thereby; (2) a right control arm coupled to and between the right wheel and the chassis to pivot with respect to the chassis about a right control arm pivotal axis; and wherein said at least a first hydraulic motor is coupled to both of the left side suspension wheels to drive the left side wheels at the same speed, and wherein said at least a second hydraulic motor is coupled to both of the right side suspension wheels to drive the right side wheels at the same speed.
