Передний ведущий мост

Номер: RU0000195438U1

Полезная модель относится к области автомобилестроения, а именно к системе управления трансмиссией автомобиля и способу преобразования крутящего момента.Технический результат, достигаемый заявленным решением, заключается в улучшении надежности и ремонтопригодности конструкции переднего ведущего моста.Указанный результат достигается тем, что в переднем ведущем мосте, содержащем картер, крышку картера и кожух полуоси, крышки-фланцы подшипников полуосей крепятся к картеру и кожуху полуоси болтами, при этом одно из регулировочных колец дифференциала при установке его в картер не имеет упора в корпус, а соприкасается с подшипником, затем с торца поджимается крышкой-фланцем от усилия заворачивания болтов, что обеспечивает регулировку осевого натяга подшипников дифференциала. Кроме того, на крышке-фланце размещается гнездо сайлентблока, что позволяет разгрузить крышку картера от усилий, возникающих в сайлентблоке, надежно обеспечивая герметичность разъема. Размещение гнезд сайлентблоков в крышках-фланцах, отдельно от картера, увеличивает расстояния точек крепления моста к подрамнику, что позволяет получить оптимальную нагрузку на всех опорах моста.

The striper has a solid direct drive axle 12 powered either by chain, belt, gears, hydraulics, etc. 14 . Two wheels 16 are attached to a solid axle 12 by means of adjustable friction devices 18 that transfer torque—stacked hardened thrust washers 20 with spring washers 22 to maintain a constant drive torque with ability to have limited slip at a specific load range. The spring washers 22 allow consistent load over long periods of wear. When each tire 24 is properly loaded “equally” the striper 26 will have natural ability to travel in a straight forward motion over bumpy surfaces specifically grass (turf), not common with standard type differentials that power only the least resistant wheel 16 . When cornering the inside wheel 16 will slip as necessary based on the turning radius. When the wheels 16 are overloaded, wheels will slip, preventing damage to the drive mechanism (transmission) 28.

Further, in the inner rotor type motor, since a first stator is disposed so as to face a radially outer side of a large-diameter rotor, heat generated in the first stator is easily dissipated. On the other hand, in an outer rotor type motor, since a second stator is disposed so as to face a radially inner side of a small-diameter rotor, a torque radius of the small-diameter rotor can be made large, thereby making it possible to ensure a large torque capacity. Because of this, the outer rotor type motor can be made smaller in diameter than the inner rotor type motor, thereby making it possible to ensure a large space within a wheel. 1.

An object of the present invention is to reduce an axial dimension of an in-wheel motor driving device in which a motor section A and a wheel hub bearing section C are connected coaxially in series via a speed reducer section B, thereby providing a large inside space of a vehicle as well as increasing freedom of routing a power supply wires. A terminal box for the power supply wires which supply power to the motor section A is disposed on the outer circumferential side surface of the housing which holds the motor section A. The power supply wires are routed out of the terminal box to an inboard side and are anchored by an power supply wire holder which extends perpendicularly to an axial centerline of the housing. 1. An in-wheel motor driving device comprising: a motor section which rotates a motor-side rotation member; a speed reducer section which reduces and transmits rotation of the motor-side rotation member to a wheel-side rotation member; and a wheel hub connected and fixed to the wheel-side rotation member; the above three elements being disposed in series from an inboard side to an outboard side of a vehicle; wherein a terminal box for a power supply wire which supplies power to the motor section is disposed on an outboard-side end surface of a housing which supports the motor section , with a holder for anchoring the power supply wire routed out of the terminal box to an inboard side being provided on a housing which supports the motor section.2.

The electrical vehicle includes a shift lever and a clutch pedal for pseudo-realizing the manual gear change operation of the MT vehicle, and a controller for controlling the operation of the electric vehicle. The shift lever is operated by the driver to select an arbitrary virtual gear stage mode from among a plurality of virtual gear stage modes in which torque characteristics with respect to the rotational speed of the electric motor are stepwise different. The clutch pedal is operated by the driver when the shift lever is operated. The controller calculates the virtual engine speed of the virtual engine based on the virtual gear stage mode selected by the shift lever and the operation amount of the clutch pedal, and displays the virtual engine speed on the display. 1. An electric vehicle that includes an electric motor for transmitting torque to a wheel , and does not include an actual engine , a transmission connected to the actual engine , and a clutch mechanism connected to the actual engine , the electric vehicle comprising:a pseudo-shifter for selecting an arbitrary virtual gear stage mode among a plurality of virtual gear stage modes in which torque characteristics of the electric motor differ in stages with respect to a rotational speed of the electric motor;a pseudo-clutch operated by the driver when the pseudo-shifter is operated and configured to simulate an operation of the clutch mechanism; anda controller configured to control the electric vehicle,wherein the controller is configured to execute:a calculation process of calculating a virtual engine speed, which is a rotation speed of the virtual engine when a torque transmitted from the electric motor to the wheel is assumed to be the torque transmitted from the virtual engine to the wheel via the virtual clutch mechanism and the virtual transmission, based on the virtual gear stage mode selected by the pseudo-shifter and an operation amount of the pseudo-clutch, anda display process of displaying ...
