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.

A C-spring contains an inner spring that is spaced apart from the outer primary spring. In one example usage, the upper and lower legs of the C-spring have rear regions respectively configured for being mounted to a tubular frame tool frame member of a ground working implement, such as a disk, and to a bearing housing.

A load sensor disposed between an air suspension assembly of a vehicle and a vehicle suspension, wherein the load sensor generates a load signal which varies based on an amount of force transferred from said vehicle frame to said vehicle suspension, wherein the load signal can be received by a load calculator to allow calculation of the load exerted from said vehicle frame to the vehicle suspension.

A bearing eye for a leaf spring for sprung support of a vehicle component on a vehicle body of a vehicle may include a through opening and a torsion spring therein, and a first catch. The bearing eye may provide pivotable mounting of the leaf spring on the vehicle body. The torsion spring is twistable relative to the bearing eye and connectable non-rotatably to the vehicle body. The first catch may project radially inwardly into the through opening, and the torsion spring has a second catch that projects radially outwardly into the through opening. The first and second catches may form a locking engagement which, depending on a degree of relative twisting between the bearing eye and the torsion spring, stops the relative twisting.

A tandem axle assembly includes a first slipper spring and a second slipper spring. The two slipper springs are configured or oriented in series with the slipper ends of the two slipper springs oriented toward each other. A keeper for a tandem axle suspension assembly is also disclosed.

The invention relates to a first leaf spring bracket having a longitudinal axis and a transverse axis which is configured to be secured to a vehicle frame and which receives a rear end portion of a leaf spring so as to allow the leaf spring rear end portion to slide longitudinally relative to the first leaf spring bracket, characterized in that the first leaf spring bracket comprises an insert comprising an insert pad extending transversally and two perpendicular arms, the insert comprising a bottom surface and a top surface and being made of austempered ductile iron, and a bracket comprising a bracket pad extending transversally and two perpendicular arms, the bracket comprising a bottom surface and a top surface, the bottom surface of the bracket pad being configured to receive the top surface of the insert, the bracket being made of spheroidal graphite cast iron.

A leaf spring may include: an upper plate provided with arc-shaped portions which are integrally formed on both end portions thereof, respectively, for forming spring eyes; a lower plate disposed to overlap a lower side of the upper plate and provided with arc-shaped portions which are integrally formed on both end portions thereof, respectively, and face the arc-shaped portions of the upper plate to form the spring eyes; clamping units installed to restrain the both end portions of the overlapped upper and lower plates from being separated from each other; and a central fastening unit configured to fasten central portions of the overlapped upper and lower plates.

An electrically controlled suspension includes a first spring with a first end and a second end, where the first end of the first spring is connectable to a forward frame bracket of a frame of a vehicle and where the second end of the first spring is connectable to a rear frame bracket of the frame of the vehicle via a rear spring support. The suspension includes a second spring with a first end and a second end, where the second end of the second spring is connected to the second end of the first spring. An electrically operated suspension control actuator is provided where the first end of the second spring is connected to the electrically operated suspension control actuator.

The present invention relates to a control unit for controlling a chassis system between at least a ground contact point and a frame of a vehicle, the chassis system comprising a leaf spring and a chassis arrangement, said chassis arrangement is adapted to receive a chassis condition input signal and to control a chassis condition of said chassis arrangement in response to said chassis condition input signal, said chassis system further comprising a strain gauge adapted to issue a strain gauge output signal indicative of a strain in said leaf spring, wherein said control unit is adapted to receive said strain gauge output signal and to issue said chassis condition input signal to said chassis arrangement on the basis of said strain gauge output signal. The invention also relates to a method, a chassis system, and a vehicle.

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.
