A drop axle lift kit for a golf cart includes a base plate. Each support arm of a pair of support arms is positioned proximate a respective lateral side of the base plate. Each support plate of a pair of support plates is mounted to a respective support arm of the pair of support arms at a distal end of the respective support arm. A pair of rod end bearings is configured to rotatably support a front steering spindle of the golf cart such that the front steering spindle of the golf cart is rotatable about an axis. The pair of rod end bearings is mounted to one of the pair of support plates such that an angle defined between the axis and vertical is adjustable in order to change a canter of a wheel on the front steering spindle of the golf cart.

A spring suspension includes a support assembly, two shock absorbing columns, two shock absorbing springs, two suspension rocker arms, two connectors and two connecting rods. The two shock absorbing columns are arranged on the support assembly symmetrically. The two suspension rocker arms are arranged on two ends of the support assembly in an opposing manner. Each shock absorbing spring sleeves the corresponding shock absorbing column which is also movably connected to the corresponding connector. Each of the connectors and the corresponding connecting rod are coaxially arranged on a cart body, and an articulation point between the connector and the connecting rod is located between the two shock absorbing columns. Each of the connecting rods is movably connected to the corresponding suspension rocker arm. The spring suspension of the utility model has a simple structure and is capable of improving the off-road performance of a golf cart.

A golf car includes a floor panel between front wheels and rear wheels. The floor panel includes first and second panels. An opening is provided in the second panel. A groove communicates with the opening, and is continuous from the second panel to the first panel. The groove is covered by a lid. External air from the groove is supplied by a fan into a shroud which covers a cylinder body and also into a muffler cover which covers a muffler. External air from an air intake duct, which faces the groove, is cleaned by an air cleaner and then supplied into the engine.

A robot includes a body having an internal opening. The robot further includes a first wheel configured to deploy out of the internal opening and to retract into the internal opening. The robot further includes a second wheel configured to deploy out of the internal opening and to retract into the internal opening. The robot further includes a sensor configured to determine a location of the robot. The robot further includes a controller configured to control each of the first wheel and the second wheel, wherein in response to the location of the robot being at a predetermined location, the controller is configured to cause the second wheel to deploy out of the internal opening and to cause the first wheel to retract into the internal opening.

A mobile robot driving wheel deforming device is capable of changing a wheel base and a mobile robot comprising same. To this end, provided is a mobile robot (100) driving wheel deforming device comprising: a first driving wheel (200) for driving the mobile robot (100); a third arm (152) connected to the first driving wheel (200); a second driving wheel (210) for driving the mobile robot (100); a fourth arm (154), one end of which is connected to the second driving wheel (210), and the other end of which is connected to the third arm (152) such that same rotates integrally; a third driving wheel (220) for driving the mobile robot (100); a second arm (114), one end of which is connected to the third driving wheel (220); a second shaft (150) installed in an area in which the third arm (152) and the fourth arm (154) are connected, thereby rotating the third arm (152) and the fourth arm (154); and a second-shaft servomotor (330) for rotating the second shaft (150).

A front suspension lift kit for a golf cart includes a kingpin sleeve and a kingpin. The kingpin is configured to extend through both the kingpin sleeve and a steering knuckle of the golf cart. A frame spacer is mountable to a frame of the golf cart, and a leaf spring is mountable to the frame spacer. The frame spacer is configured for positioning the leaf spring such that the leaf spring is spaced from the frame of the golf cart when the frame spacer is mounted to the frame of the golf cart and when the leaf spring is mounted to the frame spacer.

A golf car includes a floor panel between front wheels and rear wheels. The floor panel includes first and second panels. An opening is provided in the second panel. A groove communicates with the opening, and is continuous from the second 104 to the first panel. The groove is covered by a lid. External air from the groove is supplied by a fan into a shroud which covers a cylinder body and also into a muffler cover which covers a muffler. External air from an air intake duct, which faces the groove, is cleaned by an air cleaner and then supplied into the engine.

An electric kart has a frame, a seat, four wheels, an electric motor operatively connected to two of the wheels, and at least one battery operatively connected to the electric motor. The at least one battery has a support structure mounted to the frame of the electric kart, and battery cells positioned on the support structure such that there is at least one air passage defined between the battery cells. Air passes through the at least one air passage when the electric kart is in motion to cool at least some of the battery cells. A battery for an electric kart is also disclosed.

A robot according to an embodiment of the present disclosure may comprise: a base; a driving wheel protruding downward from the base; a plate spaced upward from the base; a through hole formed at the plate; a suspension bar including a shaft part rotatably connected to the base and vertically extending upward, and a screw part vertically extending from an upper end of the shaft part toward the through hole; a slider sliding along the shaft part and connected to the driving wheel; a bushing top configured to move up and down along the screw part when the suspension bar rotates; a spring located on an outer circumference of the suspension bar and located between the bushing top and the slider; and a motor disposed above the plate and connected to the screw part through the through hole to rotate the suspension bar.
