Abstract
The invention discloses a torque guide differential. The power output of half shafts on the two sides of the same axle is regulated, so that a vehicle can turn more easily and safely. The torque guide differential consists of two planetary gear sets sharing a planetary carrier, wherein the planetary carrier is connected with a differential case; a shaft and gears in key connection with the two ends of the shaft form a group, and are arranged on the differential case through bearings and holes matched with the bearings in the differential casing, the gear at one end is meshed with a gear in key connection with a sun gear in the planetary gear set on the same side, and the gear at the other end is meshed with a gear ring in the planetary gear set on the other side; for the other group of shaft and gears, the gear in key connection with the sun gear in the planetary gear set on one side and the gear ring in the planetary gear set on the other side are connected in the opposite direction in the same way.
Description
Technical field:
The present invention relates to a kind of differential mechanism that can regulate same bridge both sides semiaxis Power output size respectively.
Background technique:
When precursor vehicle is turned, due to the effect of car load center of gravity and centrifugal force, vehicle driving trace is made often to be greater than actual steering angle, namely understeering; Then drive rear driving force direction and a front-wheel steer direction in bend forms a thrust angle, easily makes Vehicular turn excessive, even causes unconscious whipping, make vehicle be in the driving condition of relative risk, easily meet accident.And the vehicle having installed this kind of differential mechanism additional is applied to more multi-driving force in same bridge bend outboard wheels by differential mechanism in negotiation of bends, thus produce one to curved interior thrust, offset the load of a part of centrifugal action on front-wheel, make the tracking of vehicle in bend better, cross curved lighter, safer.At present, the moment of torsion that this kind of moment of torsion guiding differential mechanism controls same bridge both sides semiaxis respectively mainly with the situation of the automatically controlled slice clutch that rubs exports; Because having various sensing, control, actuator, making this kind of differential design complexity, volume is large, cost is high, is applied in large-scale high-end SUV, in minority's vehicles such as high-end sporty motor vehicles more.
Summary of the invention:
The invention provides a kind of moment of torsion guiding differential mechanism, while can regulating same bridge both sides semiaxis Power output size respectively, without extra power unit, electronic device, electrical control actuator, power adjustment is all completed by gear, pure mechanical structure.
The technical solution adopted for the present invention to solve the technical problems is: the planetary gear set of two groups of common planet carrier, and planet carrier is connected with differential carrier; The gear that axle is connected with axle two ends key forms one group, by bearing and differential carrier are arranged on differential mechanism shell with the hole of bearing fit, wherein one end gear and the gears meshing be connected with sun gear key in homonymy planetary gear set, the other end gear engages with the gear ring in opposite side planetary gear set; Combination, the gear be connected with sun gear key from contrary connection side, direction planetary gear set in a like fashion and the gear ring of opposite side of another group axle and gear.When differential mechanism carries out differential action, side semiaxis produces speed discrepancy relative to differential carrier, semiaxis drives homonymy sun gear to drive the gear synchronous be connected with sun gear key to rotate, and by the transmission of power of axle on differential carrier and Gear combination, makes the ring gear against rotation in opposite side planetary gear set; Changed the size of sun gear ouput force by the relative rotation speed changing gear ring and planet carrier in planetary gear set, reach the object regulating both sides semiaxis power respectively.
The invention has the beneficial effects as follows: guiding power is gear transmission, and power loss is little; Guiding power step-less adjustment, the theoretical reaction time is zero; Structure is simple, compact.
