Problems solved by technology

Compared with two-wheel drive (2WD), four-wheel drive has only doubled the number of driving wheels, but the technical difficulties have increased many times.
Therefore, the requirements for the precise controllability of the vehicle's moving position are getting higher and higher. The traditional vehicle's active steering of the front wheels and passive steering of the rear wheels can no longer meet the requirements of precise controllability in crowded conditions.

Embodiment approach 1

[0036] The present embodiment is a four-wheel drive mode in which the engine and the motor module are combined. The engine drives the left and right wheels 1, 1', and the motor drives the upper and lower wheels 7, 7'. figure 1 , 2 , 3, 4, 5 further explain the specific content and implementation process.

[0037] The four wheels 1, 1', 7, 7' are arranged on the 4 corners of the "◇" shape, wherein, the left wheel 1, the left steering kingpin assembly 2, the left " "Type Cantilever 3, Driver 6, Right" "Type cantilever 3', right steering kingpin assembly 2', right wheel 1' constitute the left and right direction steering drive axle, and the upper wheel 7, the upper electric clutch 22, the upper motor 23, the middle cantilever 8, the lower motor 23', the lower Electric clutch 22 ', lower wheel 7 ' constitute up and down direction driving axle, left and right direction steering driving axle and up and down direction driving axle form a cross type " ten " font structure driving ...

Embodiment approach 2

[0053] The present embodiment is the anti-skid driving mode of the left and right wheels 1, 1', which is a simplified form of Embodiment 1, or the anti-skid driving mode of the middle row of wheels. combined with figure 1 , 2 , 3, 4, and 6 illustrate the specific content and implementation process of this embodiment.

[0054] In the four-drive mode of the left, right, up, and down wheels 1, 1', 7, 7' in Embodiment 1, only two driving speeds N1, N2 are reserved, and two driving speeds N3, N4 are cancelled. Promptly remove the power and transmission parts of the upper and lower two wheels 7, 7 ', change the two wheels 7, 7 ' into passive wheels, and only utilize the rotating speed N1, N2 to drive the left and right two wheels 1, 1 '.

[0055] First remove the upper and lower motors 23, 23' from the driver 6 via screws I34 and I34', then remove the upper and lower spline half shafts 43, 43', universal joint V21 and universal joint V21', and upper and lower electric clutches 22 ...

Embodiment approach 3

[0058] This embodiment is the electric drive mode of the upper and lower wheels 7, 7', which is another simplified form of Embodiment 1, or the electric drive mode of the middle train wheel. combined with figure 1 , 2 , 3, 4, and 7 illustrate the specific content and implementation process of this embodiment.

[0059] In the four-drive mode of the left, right, up, and down wheels 1, 1', 7, 7' of Embodiment 1, only two driving speeds N3, N4 are reserved, and two driving speeds N1, N2 are canceled. Promptly remove the power and transmission parts of the left and right two wheels 1, 1 ', change the two wheels 1, 1 ' into passive wheels, and only utilize the rotating speed N3, N4 to drive the upper and lower two wheels 7, 7 '.

[0060] First remove the driver 6 via the screw I34 and the screw I34' respectively, then use the screw I34 to directly connect the upper and lower motors 23, 23' together and install them on the vehicle body or vehicle frame through the corresponding rub...

Abstract

The invention relates to a rhomboid wheel-arranged cross-shaped axle 4WD (4 wheel drive) mechanism which comprises four wheels, a driver, suspensions, steering king-pin assemblies and a fore-and-aft steering driving mechanism; and the 4WD mechanism is characterized in that the four wheels (left, right, upper and lower wheels) are rhomboidally arranged at four corners; the left wheel, a left steering king-pin assembly, a left suspension, the driver, a right suspension, a right steering king-pin assembly and the right wheels form a left-and-right steering drive axle; the upper wheel, an upper electric clutch, an upper electromotor, a middle suspension, a lower electromotor, a lower electric clutch and the lower wheel form an up-and-down drive axle; and the left-and-right steering drive axleand the up-and-down drive axle form an intersecting cross-shaped drive axle. By using the 4WD mechanism provided by the invention, the rolling uniformity of the wheels on the road surface is improved; a modularly combined drive mode of an engine and an electromotor is realized; the 4WD mechanism has an antiskid 4WD function; and the initiative steering of the front and rear wheels is realized, thereby improving the accuracy of car motion position control.

Description

technical field [0001] The invention relates to a diamond-shaped wheel arrangement cross bridge structure of a walking machine, which is especially suitable for a four-wheel drive mechanism for turning front and rear wheels of an automobile. Background technique [0002] In order to improve the off-road capability of the car, the car adopts a four-wheel drive (4WD). Compared with two-wheel drive (2WD), four-wheel drive has only doubled the number of driving wheels, but the technical difficulties will be increased many times. For 4-wheel drive, it is necessary to eliminate the mutual interference between the four wheels caused by the different speeds of the four wheels when driving on a curved road. Therefore, a differential should be installed between the two driving wheels of the front axle, a differential should also be installed between the two driving wheels of the rear axle, and a differential should be installed between the front axle and the rear axle, so 4 The whee...
