Abstract

The invention relates to an electrical bridge driving system and a vehicle and discloses the electrical bridge driving system for the vehicle. The electrical bridge driving system for the vehicle comprises an electric motor (20), a first transmission shaft (31), a speed changing device (40), a first gear (61), a second gear (62), a differential mechanism (70) and a gear shifting device (50), wherein the the first transmission shaft (31) is connected to the electric motor (20) in an anti-torsion manner; the speed changing device (40) is arranged on the first transmission shaft (31) in a rotatable manner; the first gear (61) is arranged on the first transmission shaft (31) in a rotatable manner and connected to an output end of the speed changing device (40) in an anti-torsion manner; the second gear (62) is arranged on the first transmission shaft (31) in a rotatable manner; the differential mechanism (70) comprises an input gear (71); the gear shifting device (50) is arranged on the first transmission shaft (31), is positioned between the first gear (61) and the second gear (62) and is used for selectively transmitting the power of the electric motor (20) to the input gear (71) ofthe differential mechanism (70) through the first gear (61) or the second gear (62).

Description

technical field [0001] The present invention relates to bridge drive systems. More specifically, the present invention relates to bridge drive systems with variable speed functionality. Background technique [0002] Axle drive systems are used in hybrid or pure electric vehicles. For an axle-driven system that implements a variable speed function, it is difficult to find a compromise between axle torque and maximum vehicle speed. Therefore, in the prior art, this problem is solved by the bridge drive system with different layout schemes, including parallel structure or coaxial structure, and involves the use of cylindrical gear sets or planetary gear sets and the like. [0003] It is difficult to obtain large transmission ratios in compact layout schemes with parallel structures and spur gear sets. Patent US2017175863 discloses a parallel layout scheme of an electric bridge drive system, in which a two-speed transmission ratio is achieved through an intermediate shaft and...
