185 results about "Portal axle" patented technology

A drive apparatus (1) for a motor vehicle has a hollow portal axle (2) that accommodates two electrical machines (4). Wheels (12) are mounted rotatably at opposite ends of the portal axle (2) and can be driven by the electrical machine (4) associated with the respective wheel. A step-down gear mechanism (8, 9) is arranged between each electrical machine (4) and the respective wheel (12) and a separate connection from the respective wheel to the step-down gear mechanism, permits the wheel to be mounted in a non-rigid manner. The respective step-down gear mechanism (8, 9) is connected to the respective wheel (12) by a cardan shaft (10).

A gear box assembly as used in an inverted portal axle or transfer case includes a drive gear and at least one driven gear in meshing engagement with the drive gear at a contact point. A gear housing closely surrounds portions of an outer circumference of the drive and driven gears to form a baffle area. The gear housing includes an discharge orifice that is located near the contact point and a fluid gallery that extends from the discharge orifice to other locations within the gear housing. As the drive gear drives the driven gear, fluid is pumped into the discharge orifice and through the fluid gallery to fluid outlets positioned at desired locations to lubricate other gear box components. Radial inlets with elongated chamfers and stator vanes can be formed within the gear housing to draw air ingested during pumping away from the discharge orifice. Additionally, a bypass loop can be used to scavenge unwanted air ingested into meshing gear teeth.

An actuating device for a gear shifting transmission. The actuating device includes a selector lever which has stable selector lever positions, and a detent mechanism with a detent element and notched gate, the detent element is connected to the selector lever. The notched gate is disposed on a gate shaft that rotates when actuated. The gate shaft includes at least one helical return groove for the detent element. Due to rotation of the gate shaft, the detent element can be transferred from a start position, along the return groove, into a target position. The selector lever position always reflects the actual gear stage of the transmission, even with shift-by-wire-controlled gear shifting transmissions. The driver is provided with reliable visual and tactile feedback about the gear state of the transmission. The actuating device is structurally reliable, has low energy consumption, produces minimal noise, and requires minimal construction space.

An independently-targeted hole-free socket comprises a protection door rotary device and a rotary conducting strip installing device, and is characterized in that a cam is installed below a protection door, a rotary frame is installed on a socket base and is used for carrying out open-closed rotation of the protection door through a rotary frame shaft, the rotary frame shaft is connected with the socket base, a spring is installed on the rotary frame shaft, and the protection door is installed on a protection door shaft which is installed on a protection door shaft frame. When a plug is pressed on the protection door, the protection door rotates downwards, so that plug holes are exposed out, after the plug is plugged into the plug holes, the cam behind the protection door pushes the tail of the rotary frame and enables the tail of the rotary frame to rotate outwards, a rotary frame head with a conducting strip rotates inwards through a lever principle and is tightly clamped on a plug pin of the plug, and phenomena of virtual connection and suspension connection are avoided, the appearance of the socket is like a sealed cube, no plug holes can be seen, security coefficients are greatly improved, phenomena of the virtual connection, the suspension connection, ceaseless spark and enlarged resistance do not occur, and the service life is greatly prolonged.

A carburetor having a throttle valve co-rotatable with a small diameter throttle shaft having a free end protruding from an exterior side surface of the associated carburetor body. A throttle lever detent arm is co-rotatable on and with the throttle shaft free end adjacent each body surface. Interengageable detents on the detent arm and body surface are spaced radially away from the throttle shaft rotational axis by a distance, for example, of about three times the shaft diameter. The arm and body detents are releasably engageable with one another for thereby yieldably holding the detent arm and hence the throttle shaft and associated throttle valve in any one of a plurality of selected angular settings. Hence, the angular tolerance variation on the set positions of the throttle valve blade as controlled by the detents is now, for example, approximately three times more precise so that the tolerance limits for such positions are now rendered three times tighter than otherwise would be possible when utilizing the prior art. Hence manufacturing tolerances do not need to be tightened up in order to achieve the exemplary three-fold improvement in operational tolerances of the carburetor throttle control detent mechanism. The invention thus provides a low cost throttle control detent mechanism that enables fine increment, positive stops at predetermined valve blade settings, such as the W.O.T. (wide-open throttle), idle and closed valve positions.

An axle system includes an axle shaft offset located within an axle center beam housing. The axle shaft is located in a recess in a top wall of the axle center beam shaped with slopes to maximize clearance to the bottom of the vehicle floor panels. The pneumatic brake cylinders define a cylinder axis angled within an angular range from a generally vertical orientation for enhanced packaging.

The invention discloses a multi-purpose self-return positioning door shaft which comprises a shell. The shell is internally provided with a permanent base and a moveable plate. A spring is installed between the permanent base and the moveable plate. The moveable plate is connected with a guide device. The moveable plate is provided with a positioning slot and a side plate which is provided with a through slot. A rotary shaft is connected with the shell through a first bearing and a second bearing. The first bearing is located at one end of the rotary shaft and the second bearing is located in the middle of the rotary shaft. The other end of the rotary shaft is threaded out of the shell, a rotary bracket is installed on the rotary shaft, and a first roller, a second roller and a convex pillar are installed on the rotary bracket. The multi-purpose self-return positioning door shaft provided by the invention has the advantages that a bidirectional free door has the functions of starting positioning, self-returning and limiting, and is simple in structure, agile to open and close, accurate to position, convenient to process, low in production cost, long in service life and the like.
