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.

A connecting arrangement for connecting a shaft to a component is provided. The connecting arrangement includes at least one adapter device with is connectable to the shaft at least in a force-fitting and/or form-fitting manner, and contact surfaces of the component and of the adapter device are configured in a manner matching each other to inhibit rotation relative to one another about a longitudinal axis of the adapter.

A leaf spring apparatus for a vehicle suspension includes a leaf spring, a carrier disposed on an end portion of the leaf spring and mounted on a wheel of a vehicle, a first connection unit connecting the end portion of the leaf spring and the carrier to each other, a cross member disposed on top of the leaf spring and supporting a body of the vehicle, and a second connection unit connecting the leaf spring and the cross member to each other.

Provided herein is a driving apparatus for transporting a loaded object, which allows a drive-wheel to always be in contact with the ground even when the ground is uneven. The driving apparatus includes a loading plate (140, 240) on which a loaded object is loaded, a first support (110, 210) connected to a lower portion of one side of the loading plate (140, 240), a second support (120, 220) connected to a lower portion of the other side of the loading plate (140, 240), a hinge (130, 230) configured to connect the first support (110, 210) to the second support (120, 220) in a hinge structure, at least a pair of drive-wheels (160, 260) coupled to both sides of a lower portion of the second support (120, 220), and a driver configured to rotate and drive the drive-wheels (160, 260).

Trailers or other towed apparatuses are used to transport agricultural equipment. This can include combine heads, such as the heads for corn or soybean. The combine heads are extended on the trailer in an elongated manner that is in the longitudinal length or direction of the travel of the trailer. Due to the length of the trailer, it is advantageous to construct the trailer out of multiple segments that are bolted together to for an elongated unit. The trailer includes one or more rear axles that can be position-adjustable to adjust the wheelbase for the trailer and to account for equipment of various sizes. A rear hitch at the distal end of the trailer allows for the trailer to connect to and/or haul additional equipment.

One variation of a system includes a bogie including: a chassis; a first set of latches configured to transiently engage a first subset of engagement features, in a first array of engagement features on a left rail and in a second array of engagement features on a right rail of the trailer, to retain the bogie below a floor of the trailer; a driven axle suspended from the chassis; and a motor coupled to the driven axle and configured to output torque to the driven axle and regeneratively brake the driven axle. The system further includes a battery assembly: including a second set of latches configured to transiently engage a second subset of engagement features, in the first array of engagement features and in the second array of engagement features, to retain the battery assembly adjacent the bogie; and configured to receive electrical energy from the motor.

An emergency trailer wheel assembly for temporarily replacing a trailer wheel includes a frame member with a mounting bracket attached on a first end of the frame member and configured for attaching to a leaf spring of a trailer and a wheel rotatably attached to a second end of the frame member.

An adjustable front axle includes an axle housing; an axle tube connected to an end of the axle housing; an inner-C-forging disposed on the axle tube at an end away from the axle housing; and a mounting apparatus configured for detachably fixing the inner-C-forging to the axle tube. The inner-C-forging is provided with a first angle adjustment structure, the axle tube is provided with a second angle adjustment structure. The mounting apparatus is disposed on the axle tube, and capable of cooperating with the inner-C-forging to fix the inner-C-forging to the axle tube. The first angle adjustment structure and the second angle adjustment structure have different cooperation positions such that the inner-C-forging has different installation angles relative to the axle tube. A vehicle is also provided.

A low-floor electric axle assembly including: an axle housing, two hub motors, two planetary gear reducers, two hubs, a brake system, two C-shaped beams, and a suspension system. Mechanical mounting of the suspension system is compatible with a conventional axle. The axle housing has a left and right symmetrical dumbbell-shaped structure configured to bear a weight of a vehicle. The hub motors are inner rotor type motors and are separately arranged at two ends of the axle housing left and right symmetrically. The hub motors are arranged coaxially with two wheels respectively. Two hub motor rotors are connected to the planetary gear reducers respectively. Each of the planetary gear reducers is a single-stage planetary gear reducer. A sun gear of each of the planetary gear reducers receives power outputted by each of the hub motor. Two planetary gear reducer housings are power output ends connected to two rims respectively.
