Provided is a trailing arm riding mower suspension system that includes trailing arms adapted to support hydraulic motor units and having leading ends pivotally coupled to a mower frame by way of leading end spherical joints and trailing ends having hydraulic drive unit mounts, where the trailing arms are adapted to pivot about leading end pivot locations defined by the leading end spherical joints.

This disclosure details electrified vehicle drive systems equipped with electric machine integrated axle assemblies. An exemplary electrified vehicle drive system includes a leaf spring assembly and an axle assembly mounted to the leaf spring assembly. The axle assembly may include a cradle and an electric machine mounted within the cradle. Shocks and stabilizer bar assemblies may extend between the cradle and a vehicle frame of the electrified vehicle.

In a riding mower having a frame, a mower deck supported beneath the frame, a chair on said frame and a source of motive power also supported on said frame and including two hydraulic transaxles depending beneath the frame to each selectively rotate a drive wheel. The frame is supported on forward and rear wheel assemblies with a supporting wheel. The transaxles are supported beneath the frame and pivotally secured thereto by a flange captivating vibration pillows and proximate the driven wheel and an inner pivot rod secured to the frame by apertures in downwardly depending tabs.

A truck or trailer includes a wheel, a stub axle spindle extending through the wheel and having a through bore, a step-up drive ratio unit inboard of said stub-axle spindle, an axle shaft extending through the through bore of the stub-axle spindle, and a power conversion unit operatively connected to the step-up drive ratio unit. The axle shaft is operatively connected to the step-up drive ratio unit, such that, as the axle shaft rotates with the wheel, mechanical energy from rotation of the axle shaft is converted into electrical energy. A special suspension system allows for installation of the stub axle spindle, and such suspension systems are a separate focus herein as well as being usable in combination with the power conversion elements.

A suspension system in a vehicle is provided. The suspension system includes, in one example, a hub carrier mounting structure and a hub carrier designed to couple to a wheel hub. The hub carrier mounting structure includes a mounting flange removably attached to the hub carrier and an upper case and a lower case coupled to a support beam, the upper and lower cases are coupled via a first set of attachment devices and a second set of attachment devices that are positioned on opposing sides of the upper and lower cases, where the first and second sets of attachment devices have varying vertical heights.

An assembly for a hydraulically suspended vehicle axle may have a central housing, and at least two hydraulic suspension components supported on the central housing and fluidly connected to one another by a fluid line extending at least partially through the central housing.

A fluid-sealed engine mount includes a variable orifice whose cross-section is changed according to a magnitude of engine vibration, thereby keeping a damping performance substantially unchanged at a time of large displacement vibration of an engine as compared to a time of small displacement vibration of the engine.

An electric axle drivetrain assembly for use in a vehicle. The electric axle drivetrain assembly includes a motor that is drivingly connected to at least a portion of a differential assembly. Drivingly connected to ends of the differential assembly is a first axle half shaft and a second axle half shaft. At least a portion of a first and second wheel end assembly is connected to at least a portion of an end of the first and second axle half shafts opposite the differential assembly. A vehicle suspension system having a support member has a first hub carrier portion connected to a first end portion thereof and a second hub carrier portion connected to a second end portion thereof. Connected to at least a portion of a chassis is the motor and/or the differential assembly.

A cradle assembly for housing and supporting a motor and a gearbox of an electric axle assembly. The cradle assembly has generally an “open air” design which provides a space for a motor and/or gearbox to be positioned within a pre-assembled cradle assembly and allows for easy access to the motor and gearbox for maintenance. The cradle assembly includes two end caps, a plurality of tube portions connecting the end caps and a plurality of motor mounts for supporting the motor and gearbox.

A wheel suspension (1) for a wheel (23) of a vehicle, in particular the rear wheel of a utility vehicle, driven by an electric or pneumatic motor (2), having a swing arm (3) which is mounted pivotably around a pivot axis (7) on the vehicle in a first region (4) and is supported on the vehicle in a second region (8), wherein a third region (10) of the swing arm (3) carries a part of the motor (2) which is rotationally fixed in relation to the swing arm (3) in order to transmit a torque to the wheel using a rotating part of the motor (2).
