Rear Axle And Body Patents (Class 180/56)
  • Patent number: 11441476
    Abstract: A vehicle includes an air-path portion, an engine, and a rotating fan located more rearward than first and second seats. A wind pressure near the air-path portion located on a side surface of the vehicle is detected by a pressure sensor, and based on a detection result, an ECU controls a direction of rotation of the rotating fan. The rotating fan introduces/discharges air to/from an engine room via the air-path portion. If the pressure sensor detects a negative pressure, the rotating fan is controlled so as to discharge air from the engine room via the air-path portion. On the other hand, if the pressure sensor detects zero or a positive pressure, the rotating fan is controlled so as to introduce air to the engine room from the air-path portion.

  • Patent number: 11040617
    Abstract: A vehicle transaxle comprising a plurality of mounting flanges fixedly mountable to an axle tube of the vehicle absent any additional structure for mounting the transaxle to the vehicle. The axle tube houses a wheel axle to which the transaxle is operably couplable. The transaxle additionally comprises a transaxle mounting collar that is fixedly mounted to or integrally formed with a housing of the transaxle. The mounting collar is structured and operable to have a prime mover of the vehicle mounted thereto and to support the weight/mass of the prime mover such that the prime mover is mountable to the vehicle via only the mounting collar absent any additional structure for mounting the prime mover to the vehicle such that the prime mover can be cantilevered from (e.g., suspended from) the transaxle, e.g., the prime mover is ‘free floating’.

  • Publication number: 20150096823
    Abstract: The invention relates to a system for driving the drive wheels (1) of a vehicle, comprising two sets of electric motors (2) and casings (3) (left and right). Each of the casings (3) comprises an input pinion (8) which rotates interdependently with the rotor of one of the electric motors (2) as well as with a set of gears (12) driving the ring gear (7) of a planetary gear set (4). The two planetary gear sets (4) are connected to one another by a connecting means (9) that rotates interdependently with each of the two sun gears (5) (inner planetaries). The planet carrier (6) of each of the planetary gear sets (4) rotates interdependently with a connecting means (11) of one of the drive wheels (1). The two planetary gear sets (4) perform a double differential function. The invention also relates to a method for controlling the electric motors (2) that allows the drive system to be used as a torque converter. The drive system can be fixed to the chassis frame of the vehicle.

  • Patent number: 7228924
    Abstract: An apparatus and assembly method including a sprocket hub and a locking collar for go kart vehicles and other land vehicles with drive axles is provided. The present invention eliminates the need for two locking collars on either side of the sprocket hub. The invention further provides a lightweight sprocket hub with a hub neck portion adapted to receive a single locking collar. The sprocket hub fits loosely on the drive axle. The fin-like sprocket hub arms and sprocket hub extensions each have sprocket connection holes used to connect the sprocket hub to a drive sprocket. The locking collar engages the sprocket hub neck portion by means of two flanges located on the sprocket hub.

  • Patent number: 6722455
    Abstract: A utility vehicle is provided with a middle axle that is mounted at the end of a bogey beam for both flotational and oscillatory movement relative to the frame of the vehicle. The middle axle is restrained longitudinally by support links that are pivotally connected to the frame at a location that is forward of the rear drive axle. The middle axle is formed by a pair of stub axles interconnected by a support beam that is pivotally connected to the rearward end of the bogey beam. Vertical movement of the middle axle support wheels results in a corresponding vertical movement of the rearward end of the bogey beam and a rotation of the support beam about its pivotal connection on the bogey beam. The oscillatory movement is accomplished by a pivotal connection via a ball joint between a central support bracket mounting the transverse support beam to the longitudinally extending bogey beam.

  • Patent number: 6105707
    Abstract: A tired roller is provided with a prime mover and a speed change unit of the HST type. The speed change unit includes an HST hydraulic pump of the variable displacement type driven by the prime mover and an HST hydraulic motor driven by pressure oil from the hydraulic pump, and can change a rotational speed of the hydraulic motor by varying a delivery rate of pressure oil from the hydraulic pump. Rotation of the hydraulic motor is therefore transmitted at a lower speed to a drive-axle tire train. A propeller shaft is connected to the hydraulic motor without interposition of any speed reduction mechanism, so that the propeller shaft is rotated at a high speed with a low torque. This has made it possible to form the propeller shaft smaller in diameter and hence to arrange it in a narrow space between tires in the drive-axle tire train.

  • Patent number: 5338247
    Abstract: A rear suspension for battery powered on-road scale model car of the type having a straight rear axle and a nonindependent rear suspension is disclosed. The model car includes a chassis having a central longitudinal axis with a centrally located battery pack. A pair of remotely steerable wheels are pivotably affixed to the chassis front end. A motor pod pivotably supports a pair of rear wheels interconnected by a straight rear axle and includes a mechanism for attaching an electric drive motor. The rear suspension elastically attaches the motor pod to the chassis for limited vertical bounce movement and limited torsional roll movement of the motor pod relative to the chassis. The rear suspension components are spaced sufficiently from the battery pack to provide clearance for a row of batteries oriented centrally along the chassis. The central battery design minimizes mass moment of inertia of the model car measured about the longitudinal axis resulting in improved maneuverability.
