Problems solved by technology

[0004] Disadvantage of an open differential: If one side gear is stationary relative to the other, all power entering the differential will be distributed to the wheels with less resistance
If it is a four-wheel drive vehicle with open differentials on the front and rear axles, if a single front wheel or rear wheel leaves the ground when off-road, it cannot get out of trouble

Embodiment Construction

[0026] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and which show by way of illustration specific embodiments in which the invention may be practiced. In this regard, directional terms such as "top", "bottom", "left", "right", "upper", "lower", etc. are used with reference to the orientation of the figures being described. Because components of an embodiment may be positioned in several different orientations, directional terminology is used for purposes of illustration and is by no means limiting. It is to be understood that other embodiments may be utilized or logic changes may be made without departing from the scope of the present invention. The following detailed description should therefore not be taken in a limiting sense, and the scope of the invention is defined by the appended claims.

Abstract

The invention discloses a differential system for a vehicle. The differential system comprises a driving device, a two-direction overrunning clutch and a driving wheel, wherein an output shaft of thedriving device is connected with a driving shaft connected to the driving wheel in a matched mode, the two-direction overrunning clutch comprises a driving piece and a driven piece, the driving pieceis connected with the driving shaft, the driven piece is connected with the driving wheel, and the two-direction overrunning clutch is used for transmitting two-direction torque output from the driving device to the driving shaft. The differential function of the differential system is achieved through the two-direction overrunning clutch, and the structure of the vehicle differential system is greatly simplified.

Description

technical field [0001] The invention relates to the technical field of vehicle drive, and in particular to a differential system for a vehicle. Background technique [0002] The automobile transmission system is mainly composed of clutches, transmissions, universal transmissions and drive axle differentials, etc., which can make the left and right (or front and rear) drive wheels rotate at different speeds. The differential is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. rolling motion. The differential is set up to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive four wheels at the same time, all the wheels must be connected. If only the four wheels are mechanically connected together, the car cannot rotate at the same speed when driving in a curve. In order to make the car The rotation speed of the curve driving remains basically the same. At this time, the middle differe...
