A three wheeled vehicle is provided that can include a frame, a steerable front wheel secured to a front end of the frame, a first trailing wheel arm having a first rear wheel secured thereto and a second trailing wheel arm having a second rear wheel secured thereto, and a central suspension joint secured to the frame on which the first and second trailing wheel arm is rotatably secured on either side of the frame. Further, the vehicle can include a horizontal linkage pivotably connected on the frame at the midsection beneath the first and second trailing wheel arms and linked to an underside of the first and second trailing wheel arm between the first wheel and the central suspension joint proximal to a first end of the horizontal linkage and between the second wheel and the central suspension joint proximal to a second end of the horizontal linkage, respectively.

The invention relates to an industrial truck comprising a chassis (6), which is supported by at least two front wheels (2) and by at least one rear wheel (3) on the ground (4), a mast (8) for a load-carrying apparatus (36), which is arranged in an upright position thereon in a mast support region (54) of the chassis (6), wherein the front wheels (2) are rotatably arranged on wheel arms (50, 50) that protrude forwards from the mast support region (54) of the chassis (6), and means (62, 64; 162, 164; 262, 264) for suppressing and reducing vibrations, wherein at least one of the wheel arms (50, 50), preferably both wheel arms (50, 50), is/are split into at least two wheel arm portions (50a, 50b), which are mounted by means of a bearing arrangement (56; 156) so as to be able to perform movements relative to one another, wherein the means for suppressing or reducing vibrations are designed or operable to influence relative movements of the wheel arm portions (50a, 50b), in order to ensure that any impacts owing to unevenness of the ground during travel can only be passed on to the chassis (6) and the mast (8) by means of the wheel arms (50, 50) in a reduced, and absorbed and damped manner, and that any mast vibrations are damped.

A rocking arm structure includes an arm body, a first wheel assembly connected to the arm body, a second wheel assembly connected to the arm body, and a shaft assembly disposed between the first wheel assembly and the second wheel assembly. The arm body can rotate relative to the main body around the shaft assembly, and drive the first wheel assembly and the second wheel assembly to revolve in a same direction around the shaft assembly. The first wheel assembly and the second wheel assembly are both steering wheel assemblies or both directional wheel assemblies.

A resisting force change mechanism includes a first portion and a second portion configured to change a resisting force against relative displacement. The first portion is supported on any one of a first side member, a second side member, a first cross member, and a second cross member of a link mechanism where at least a portion thereof is superposed on one member at all times. The first portion is aligned with the one member and a steering shaft at the front. The second portion is supported on any other one of the body frame, the first side member, the second side member, the first cross member, and the second cross member that is displaced relative to the one member on which the first portion is supported. The second portion is located at a position where at least a portion thereof is superposed on the other member at all times.

The twist axle assembly includes a twist beam which is made of a single integral piece, extends along a length between opposite ends and the twist beam has an open cross-sectional shape between the ends. The twist beam is stamped into a U-shape with a middle section that extends in a first direction between a pair of trailing arm sections. The trailing arm sections extend at least partially in a second direction that is generally transverse to the first direction to reduce twisting stresses within the trailing arm portions during operation of the twist axle assembly.

The present invention relates to an electronic control system for a motor vehicle, including a control device, an actuator, and at least one sensor. The control system according to the invention is characterized in that it has a sensor board for reading the data detected by the sensor, wherein the sensor board has a memory for storing actuator-specific data and an interface between the sensor board and the control device for transferring the data stored in the sensor board to the control device. The present invention also relates to a method for operating this type of control system.

A brake controlling operation transmission member includes a leaning-associated deforming portion that deforms in response to turning of a body frame. A vehicle includes at least a portion of the leaning-associated deforming portion located between a first restrictor located below a lower cross portion in relation to an up-and-down direction of the body frame and a central portion in a left-and-right direction of the body frame so as to prevent movement of the brake controlling operation transmission member and a brake device.
