Title (EN) STEERING DRIVE AXLE ASSEMBLY AND VEHICLE
(FR) ENSEMBLE ESSIEU D'ENTRAÎNEMENT DE DIRECTION ET VÉHICULE
(ZH) 转向驱动桥总成和车辆
Abstract:
(EN) Provided is a steering drive axle assembly, comprising an axle housing (11), an electrodynamic assembly, a driving shaft (12) and a wheel-side structure, wherein the electrodynamic assembly comprises a motor assembly (21); and the wheel-side structure comprises a steering knuckle (31), a hub unit and an universal transmission device, with the steering knuckle (31) comprising a steering knuckle body (310); the hub unit comprising a hub shaft sleeve (32); the universal transmission device comprising a first universal joint (341), a second universal joint (344), a proximal transmission shaft (342) and a distal transmission shaft (343); and the point of intersection of the kingpin axis (A) defined by the steering knuckle (31) with the central axis (B) of the distal transmission shaft (343) coinciding with the central point of the first universal joint (341). Further provided is a vehicle having the steering drive axle assembly. The steering drive axle can also transmit the steering torque while driving the transmission of torque, i.e. realizing the functions of steering and driving at the same time.
(FR) L'invention concerne un ensemble essieu d'entraînement de direction, comprenant un carter d'essieu (11), un ensemble électrodynamique, un arbre d'entraînement (12) et une structure côté roue, l'ensemble électrodynamique comprenant un ensemble moteur (21) ; et la structure côté roue comprenant un porte-fusée de direction (31), une unité moyeu et un dispositif de transmission universel, le porte-fusée de direction (31) comprenant un corps de porte-fusée de direction (310) ; l'unité moyeu comprenant un manchon d'arbre de moyeu (32) ; le dispositif de transmission universel comprenant un premier joint universel (341), un second joint universel (344), un arbre de transmission proximal (342) et un arbre de transmission distal (343) ; et le point d'intersection de l'axe de pivot d'attelage (A) défini par le porte-fusée de direction (31) avec l'axe central (B) de l'arbre de transmission distal (343) coïncidant avec le point central du premier joint universel (341). L'invention concerne en outre un véhicule comportant un ensemble essieu d'entraînement de direction. L'essieu d'entraînement de direction peut également transmettre le couple de direction tout en entraînant la transmission de couple, c'est-à-dire, réalisant les fonctions de direction et d'entraînement en même temps.
(ZH) 一种转向驱动桥总成,包括桥壳(11)、电动力总成、半轴(12)以及轮边结构,该电动力总成包括电机总成(21);该轮边结构包括转向节(31)、轮毂单元和万向传动装置,转向节(31)包括转向节本体(310);轮毂单元包括轮毂轴套(32);万向传动装置包括第一万向节(341)、第二万向节(344)、近端传动轴(342)和远端传动轴(343);转向节(31)限定的主销轴线(A)和远端传动轴(343)的中心轴线(B)两者的交点与第一万向节(341)的中心点重合。还提供了一种具有该转向驱动桥总成的车辆。该转向驱动桥在驱动扭矩传递的同时,还能够传递转向扭矩,即同时实现转向和驱动功能。
