Spring support device and vehicle having the same
11884103 · 2024-01-30 · ·

The present document provides a spring support device and a vehicle having the same. The spring support device includes a first support unit for supporting a damper spring. The first support unit includes a first support body configured for being connected to a vehicle body, and a spring support which is detachably fixed to the first support body. Due to the separation arrangement between the spring support and the first support body, suitable first support body and spring support can be selected as required, which can satisfy requirements of different vehicles in the vehicle modification process. Since the spring support is separated from the first support body, an area between the spring support and the first support body can be sprayed before assembly when spraying protective paint. Therefore, it is convenient to spray protective paint efficiently.

Spring Seat Body for a Rigid Axle of a Motor Vehicle and Rigid Axle for a Motor Vehicle With a Spring Seat Body
20240116312 · 2024-04-11 ·

A spring seat body for connection to a rigid axle of a motor vehicle, including an upper spring seat surface, a lower seat surface, lateral edge surfaces which lie between the spring seat surface and the lower seat surface, and holding means for holding tensioning means for fastening at least one spring to the spring seat body. The lateral edge surfaces include a first edge surface and a second edge surface which face away from one another and, in the mounted state of the spring seat body on the rigid axle, run transversely with respect to the rigid axle, the first edge surface, in the mounted state of the spring seat body on the rigid axle, lying closer to an end of the rigid axle which bears a vehicle wheel than the second edge surface, and the first edge surface having an edge course which, in the mounted state of the spring seat body on the rigid axle, lies in overlap with the rigid axle. In order for the spring seat body to offer improved robustness, in particular increased fatigue strength in its connection to a generic rigid axle and thereby enable a reduction in the overall weight of the rigid axle, the invention provides that said edge course, viewed from above, is at least partially formed as an outwardly projecting, preferably convex edge course, the apex or vertex lies in a region of the first edge surface which runs along a central length range of the upper spring seat surface running transversely to the rigid axle, said central length range being less than one third, preferably less than one quarter, particularly preferably less than one fifth of the length of the upper spring seat surface. In particular, the invention relates to a rigid axle for a motor vehicle, in particular a utility vehicle, with such a spring seat body.

Bushing for use in a vehicle suspension
11953070 · 2024-04-09 · ·

A bushing includes a body that is cylindrical; a bore through the body; a channel extending along an inner face of the bore; and a groove on a substantially planar surface of the bushing and including a first end intersecting with an end of the channel and a second end extending radially from the bore.

"AFW-4" VEHICLE SUSPENSION

The invention relates to suspension design. The present vehicle suspension comprises a quadrangular frame. Each corner portion of the frame has a wheel block kinematically attached thereto so as to form two pairs of wheelsa front pair and a rear pair. On each side of the frame, longitudinal and transverse coupling cables are fastened for movement therealong inside housings. Each wheel block consists of a body that is simultaneously connected to two coupling cables. Movably mounted on the body are parallel horizontal arms, the first of which is fastened to the body by its middle portion. A knuckle with the hub of a wheel is attached to an end of the first arm and to another end of the second arm, and two coupling cable dampers are attached to the other end of the first arm. The housings of the cables are attached to the body of the corresponding wheel block. The free end of each cable is enclosed in a damper. Mounted on the cable end portions that freely project from the housings in front of a damper are spring stabilizers of the position of the wheel of the wheel block. Each coupling cable is provided with a linear actuator. The result is an increase in the stability and smoothness of movement of a vehicle.

TRAVELING CAR

A traveling car includes a car body and a driver. The driver has a motor that is attached to the car body, a drive wheel, a support that supports the drive wheel, and a transmission that transmits rotary drive force to the drive wheel. The support has a holder that rotatably supports the drive wheel and is attached to the car body so as to rotate about a rotation axis M extending in the horizontal direction. The transmission has an output pulley that is coupled to the motor and is located on the car body, an input pulley that is coupled to the drive wheel and is located on the holder, and a belt wound around the output pulley and the input pulley. The rotation axis M is located coaxial with the output pulley.
