An improved differential unit (101) for an integrated hydrostatic transmission (IHT) is provided. The differential unit comprises an input gear (200), a cross-shaft (202) disposed within a central opening of the input gear, and a pair of clutch members (204L,204R) disposed coaxial with the input gear. One of each clutch member is disposed on opposite sides of the cross-shaft. A first plurality of friction members (208) extend from each clutch member. The differential unit also comprises a pair of side couplings (210L,210R), each coaxially disposed within one of the clutch members, and a second plurality of friction members (212) extending from each side coupling. Each clutch member includes a cam surface (206) that comes in contact with the cross-shaft when the differential unit is under normal operating conditions. Alternative embodiments are also described herein.

A steerable hydraulic transaxle (15) comprises: a kingpin (26) relatively rotatably supported by a vehicle chassis (14); a housing (28) fixed to the kingpin (26); a single axle (35) disposed in the housing (28); a single wheel (36) fixed onto the single axle (15) out of the housing (28); and a hydraulic motor (10) disposed in the housing (28) so as to drive the single axle (15). A hydraulic transaxle comprises a transaxle casing for supporting left and right axles, a pair of hydraulic motors (10) disposed in the transaxle casing so as to drive the respective left and right axles (15), hydraulic ports provided in the transaxle casing so as to fluidly connect the pair of hydraulic motors (10) in parallel to a common hydraulic pump (5), and a system for restricting or canceling differential rotation of the pair of hydraulic motors.

The present invention relates to a four-wheel drive vehicle which on account of its constructive composition has very good off-road characteristics, in addition to which the vehicle can be adapted to a number of transport requirements and can act as a tool carrier. The vehicle is substantially frameless in the traditional sense with a front and a rear rigid differential axle mounted on a beam or frame extending centrally in the vehicle's longitudinal direction, where at least one of the axles can rotate about the vehicle's longitudinal axis, while at the same time both of the vehicle's axles are each steered in the opposite direction to each other about their axes perpendicularly to the vehicle's longitudinal axis.

Having three or more vehicle wheels (1, 29 and also having a diverting mechanism (4) that can independently divert each of the vehicle wheels (1, 2), a driving wheel of the vehicle wheels (1, 2) is run driven by a run drive mechanism (5) having an independent prime mover (6). Accordingly, an unusual traveling operation, which results in a in-situ swing or a sidewise movement is enabled. In an automobile of the above given construction, a travel mode switching unit (41) is provided to perform switching between a usual travel mode and an unusual travel mode. By so constructing, the switching of a travel mode between an unusual travel mode and a usual travel mode can be implemented as intended by a driver and there is no possibility that the switching may occur accidentally.

Die Erfindung betrifft eine fahrerlose Transporteinrichtung (1) zum automatischen Befördern, Aufnehmen und Abgeben von Paletten (2), mit einem im Grundriss im wesentlichen U-förmigen Fahrgestell (17) mit zwei Schenkeln, wobei auf jedem Schenkel des Fahrgestells zumindest eine lenkbare Radeinheit (11) angeordnet ist. Um ein schonendes Aufnehmen, Abgeben und Transportieren von Paletten zu ermöglichen, ist vorgesehen, dass zumindest eine lenkbare Radeinheit (11, 11') einzeln über jeweils zumindest eine Antriebseinheit (7) antreibbar ist, wobei die lenkbare Radeinheit (11, 11'), vorzugsweise jede lenkbare Radeinheit (11, 11'), zwei Laufräder (7', 7") aufweist.
摘要:
A transaxle apparatus (10;20) comprising an axle (12L,12R;22L,22R) having an axis and a housing (46,47) supporting the axle (12L,12R;22L,22R), wherein the housing (46,47) includes a first housing member (46) and a second housing member (47) which are joined to each other through a joint surface along the axis of the axle (12L,12R;22L,22R). A hydraulic motor (40) is disposed in the housing (46,47), wherein the hydraulic motor (40) includes a cylinder block (43) and a motor shaft (41) engaged to the cylinder block (43) and extended parallel to the axis of the axle (12L,12R;22L,22R). A member (62) is disposed in the housing (46,47) and incorporates a pair of kidney ports (62a,62b) fluidly connected to the cylinder block (43). A pair of caps (54a,54b) are fluidly connected to the cylinder block (43), and a gear train (135) is disposed in the housing (46,47) so as to drivingly connect the motor shaft (41) to the axle (12L,12R;22L,22R). The pair of caps (54a,54b) are disposed in the housing (46,47) so as to be fluidly connected to the respective kidney ports (62a,62b) and are extended and opened outward from the housing (46,47) so as to receive and deliver fluid from and to a hydraulic pump (30) disposed separate from the housing (46,47).
