Embodiment Construction

[0015] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0016] like Figure 1-3 As shown, the present invention mainly includes a motor 1, an upper cross arm 2, a lower cross arm 3, an axle housing 4, a large bevel gear 5, a transmission half shaft 6, a hub support 7, a wheel 8, a lock nut 9, and a hub bearing 10 , brake disc 11, small bevel gear 12, large pulley 13, positioning rod 14, synchronous belt 15, small pulley 16.

[0017] One end of the upper cross arm 2 of the double wishbone suspension is hinged to the frame through the swivel joint, point B is the midpoint of the line connecting the upper cross arm 2 and the frame hinge point, and the other end is hinged to point A with the swivel joint and the axle housing 4 ; One end of the lower cross arm 3 is hinged to the vehicle frame th...

Abstract

The invention relates to a wheel-side deceleration driving device of an equal-length double wishbone suspension, which belongs to the field of electric vehicles and comprises a double wishbone suspension, a motor, a synchronous belt, a small belt pulley, a big belt pulley, a small bevel gear, a big bevel gear, an axle housing, a transmission half shaft, a hub supporting member, wheels and the like, wherein one end of an upper cross arm is hinged with a vehicle frame through a rotating pair, the other end of the upper cross arm is hinged with the upper end of the axle housing on an A point through the rotating pair, one end of a lower cross arm is hinged with the vehicle frame through the rotating pair, and the other end of the lower cross arm is hinged with the lower end of the axle housing on a D point through the rotating pair. The B and the C respectively are middle points of a connecting line between hinged points of the upper cross arm, the lower cross arm and the vehicle frame, and the A, the B, the C and the D form a parallelogram. The motor is arranged on a middle point of the B and the C, the small belt pulley is arranged on an E point, the big belt pulley is arranged on an F point, the length between the E and the F stays the same during jumping process of the wheels, and the distance between the two belt pulleys does not change, thereby guaranteeing power to be steadily transported. The motor is fixed on the vehicle frame, thereby increasing select range of motor power, reducing unsprung mass of electric wheels, and effectively increasing controllability and harshness of a finished vehicle.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to a wheel-side deceleration driving device adopting equal-length double-wishbone suspension. Background technique [0002] With the improvement of people's living standards, cars are more and more widely used. In recent years, with the increasingly serious energy crisis and the continuous enhancement of people's awareness of environmental protection, the requirements for automobiles are getting higher and higher. Electric vehicles have incomparable advantages in energy saving, environmental protection and performance compared to traditional vehicles. They are the product of social and economic interests and energy and environmental protection requirements. They have become the mainstream of new energy vehicle development recognized by the world. [0003] Electric vehicles can be divided into centralized motor drive form and electric wheel drive form according to the different ways...
