The present invention relates to wheelchair improvements and, in particular, to a wheelchair including a monocoque structural skin according to one aspect, and a suspension assembly according to another aspect.

A computer-implemented method for designing a pin joint having a bearing member and a pin member received within the bearing member is provided. The method includes receiving, via a Graphical User Interface (GUI), at least one input related to one or more pin joint configuration parameters. The method includes receiving, via the GUI, at least one input related to one or more pin member design parameters. The method includes receiving, via the GUI, at least one input related to one or more bearing member design parameters. The method includes calculating a set of design parameters of the pin joint based on the inputs related to the pin joint configuration parameters, the pin member design parameters, and the bearing member design parameters. The method includes generating an output design of the pin joint based on the comparison between the calculated set of design parameters with a set of predefined design parameters.

An embodiment component integration type rear lower includes a body frame having an end portion of a first side and an end portion of a second side and having a predetermined length, a front-rear connection member connecting a side sill at the end portion of the first side and connecting a rear side member at the end portion of the second side, a bush mounting member coupling a bush to the end portion of the first side, and a coupled torsion beam axle (CTBA) mounting member coupled to at least one of a CTBA, a chassis spring, or a shock absorber, the at least one of the CTBA, the chassis spring, or the shock absorber being engaged with the end portion of the second side.

A suspension structure includes a pair of trailing arms (12), a beam member (13) connecting the pair of trailing arms, a bracket (21) connected to a rear end region of the trailing arm, and an in-wheel motor drive device (31) coupled and fixed to the bracket. The in-wheel motor drive device (31) is located above the rear end region of the trailing arm (12), and a lower side of the in-wheel motor drive device (12) is covered by the rear end region of the trailing arm (12) and the bracket (21).

The present invention concerns a wheel suspension 5 for a torsion beam axle 1, whereby a wheel mount 8 rotates about a virtual steering axle 18 as a result of a cornering force. According to the invention, it is further provided that a wheel mount bracket 6 with a yielding element 11 is coupled to the end 4 of a longitudinally extending swing arm 3 of the torsion beam axle 1, so that an additional steering in positive toe occurs as a result of a lateral force effect.

A trailing arm mounting bracket for connecting a trailing arm to a vehicle body includes: a fixing portion fixed to the vehicle body, a first connection plate and a second connection plate each extending from opposite ends of the fixing portion to support opposite ends of a mounting bush of the trailing arm and to which a fastening bolt fastened to the mounting bush is coupled, a first reinforcement portion to connect and reinforce the portions where the first and second connection plates and the fixing portion are connected with a truss structure, and a second reinforcement portion to connect and reinforce the first connection plate and the second connection plate at a position in the front of the mounting bush.

A suspension actuation assembly can include first and second support assemblies that are displaceable relative to one another in a first direction of travel. A connector assembly can extend between and operatively connect the first and second support assemblies. An actuator assembly can be displaceable between collapsed and extended conditions. The actuator assembly can be oriented transverse to the first direction of travel and can be operatively associated with the connector element such that displacement of the actuator assembly generates displacement of the first and second support assemblies relative to one another along the first direction of travel. A suspension system including such a suspension actuation assembly is also included.

The present invention relates to all terrain vehicles having at least a pair of laterally spaced apart seating surfaces.
