  • Patent number: 11858545
    Abstract: A vehicle having a support structure includes a front structural section for receiving a front axle assembly and a rear structural section opposite the front structural section in the longitudinal direction of the vehicle. A support part is arranged between the front structural section and the rear structural section as part of the support structure. The support part has a support wall which runs in a self-contained manner in the circumferential direction transversely with respect to the longitudinal direction of the vehicle.

  • Patent number: 11617293
    Abstract: A work vehicle includes a first ground-engaging implement and a second ground-engaging implement connected to a chassis. The first ground-engaging implement moves within a first movement envelope with respect to the chassis, and the second ground-engaging implement moves within a second movement envelope with respect to the chassis. A lift arm is connected to the chassis and positioned between the first and second ground-engaging implements. The lift arm moves along a range of movement between a raised position and a lowered position. The lift arm is entirely positioned outside both of the first movement envelope and the second movement envelope within the entire range of movement between the raised position and the lowered position, such that the lift arm is permitted to move along the entire range of movement between the raised position and the lowered position without abutting the first movement envelope or the second movement envelope.

  • Patent number: 11613177
    Abstract: One or more techniques and/or systems are disclosed for a transmission that provide power to a front axle, and fits in taller box to provide more room for the transmission. The transmission can comprise a front input shaft that receives rotational power from an engine. A front output shaft is coupled with a front axle to provide the rotational power, conditioned by the transmission, to the front axle. A rear riser gear set can be couple to the rear of the transmission to provide power from the bottom portion of the transmission to a bevel gear set that couples with, and provide rotational power to, a rear axle. In this way, the space between a rear axle centerline and front axle center line can be used by the transmission, allowing for a taller transmission to fit in the chassis.

  • Patent number: 11589492
    Abstract: A hitch that connects to a chassis of the work vehicle and rotates with respect to the chassis includes a first bracket connected to a first portion of the chassis, a first stabilizer bar connected to the first bracket, and a first hitch arm connected to the first stabilizer bar. The first hitch arm has a free end that engages a work implement. A second bracket is connected to a second portion of the chassis. The second portion of the chassis is spaced from the first portion of the chassis, so that the second bracket is spaced apart from and independent of the first bracket. A second stabilizer bar is connected to the second bracket. A second hitch arm is connected to the first stabilizer bar. The second hitch has a free end configured to selectively engage the work implement.

  • Patent number: 11292515
    Abstract: A work vehicle includes a chassis defining a longitudinal axis, a prime mover configured to move the chassis in the direction of the longitudinal axis, and a steering assembly configured to pivot a wheel relative to the chassis. The steering assembly includes a knuckle coupled to the wheel, a tie rod coupled to the knuckle and having a ball portion, a steering cylinder, and a joint assembly. The steering cylinder is slidably coupled to the chassis and configured to translate relative to the chassis along a cylinder axis perpendicular to the longitudinal axis. The steering cylinder includes a connection portion having an inner circumferential surface that partially defines a bearing pocket. The joint assembly couples the ball portion to the connection portion and includes a bearing race that is received into the bearing pocket in direct contact with the inner circumferential surface. The bearing race receives the ball portion.

  • Patent number: 11260714
    Abstract: A work vehicle includes a chassis, a prime mover configured to move the chassis along a ground surface, and a suspension assembly that couples a wheel to the chassis. The suspension assembly includes a knuckle coupled to the wheel, a first suspension arm, and a suspension cylinder. The first suspension arm includes a first portion rotatably coupled to the chassis and a second portion extending away from the first portion and coupled to the knuckle. The suspension cylinder is rotatably coupled to the chassis and to a second suspension arm. The first suspension arm and the suspension cylinder are each configured to pivot relative to the chassis about a common pivot axis.
