Abstract
The invention discloses a scattered gear differential mechanism, which comprises the main components of a differential mechanism shell, a planetary scattered gear, a gap spring, a central shaft, an inner shaft sleeve, a half-shaft gear, an inertia brake wheel and the like. For an automobile adopting the scattered gear differential mechanism, when a single driving wheel generates a track-slip, because of the increase of instantaneous acceleration, the brake shoe friction on the outer shaft surface of the planetary scattered gear and the inertia brake wheel is increased to ensure that an idling sector bevel gear floated by the gap spring is deviated, and two gaps with close angles are put together to form a self-locking gap which is close to one-half of a fixed tooth space; when a tooth top convex cambered surface between the gaps is connected with a tooth top concave cambered surface of the half-shaft gear, the half-shaft gear connected with the tooth top concave cambered surface is locked in one direction to ensure that driven wheels on two sides of the differential mechanism are driven at the same time; and when the track-slip is relieved, under the action of a driving wheel differential torsional force, the connected arc-shaped tooth tops are slipped or separated to realize automatic unlocking of the differential mechanism. The invention aims to provide a scattered gear differential mechanism with small running resistance and large self-locking locking coefficients.
Description
Technical field
The present invention relates to a kind of diffusing tooth differential mechanism.
Background technique
Automobile differential is a differential gear, is used for guaranteeing the transmission of power of each driving wheel under various moving conditions, avoids skidding between tire and ground.But after the adhesion of differential mechanism one side drive wheel was less than the vehicle operating resistance, wheel will trackslip, and influences automobile and normally moves.
Summary of the invention
The object of the present invention is to provide a kind of running resistance little, the diffusing tooth differential mechanism that the self-locking locking coefficient is big.
Diffusing tooth differential mechanism of the present invention comprises differential carrier, and differential casing is provided with planet diffusing gear outer shaft hole, internal axle sleeve footstalk hole and breach; The diffusing gear of planet is equipped with in the inside of differential carrier, the diffusing gear of each planet is made up of near the fan-shaped bevel gear amalgamation gap of 1/2nd fixing tooth distances three fan-shaped bevel gears, three interradicular space springs and three addition summations at least, the clearance plane of fan-shaped bevel gear is provided with spring hole, gap, and two ends and inside and outside fan-shaped axle are connected as a single entity; The tooth top convex globoidal radius of the diffusing gear of planet equals the diffusing tooth radius of planet, the outer shaft of the diffusing gear of planet places in the diffusing gear outer shaft hole of the planet on the differential casing, and stretch out outside the differential carrier, planet looses, and axle places in the internal axle sleeve in the gear, and internal axle sleeve and footstalk are connected as a single entity, the pommel of footstalk places in the internal axle sleeve footstalk hole on the differential casing; In the amalgamation center hole of the diffusing gear of planet central shaft is housed, differential gear is equipped with in the both sides of the diffusing gear of planet, and the Topland of differential gear is made up of the spill cambered surface that two radiuses equal the diffusing tooth radius of planet; Be expert at be scattered about like the stars the convex globoidal of gear teeth tips with can combine by concentric after the spill cambered surface of differential gear tooth top is joined; The inertia braking wheel concentric with differential gear is equipped with in the outside of differential carrier, the inner headed face of inertia braking wheel is provided with brake shoe hole and breach, breach in the inertia braking wheel on the circle is corresponding with the breach on the differential casing, in the retardation pressure spring of external diameter greater than notch depth is housed, brake shoe and buffering assembly are equipped with in the both sides in brake shoe hole, and brake shoe acts on the diffusing gear outer shaft of planet of elongation.
The outer shaft of the diffusing gear elongation of the wherein said planet of diffusing tooth differential mechanism of the present invention is the electronic control braking;
Diffusing tooth differential mechanism of the present invention does not have inertia braking wheel, brake assemblies and gap spring wherein.
Compare with existing differential mechanism, adopt the automobile of diffusing tooth differential mechanism of the present invention, it is when normal operation, the thrust of the outer shaft effect of gear elongation and inertia braking wheel is not enough so that the fan-shaped bevel gear skew of floating unloaded because planet looses, make two the tooth top convex globoidal between the gap and the spill cambered surface of differential gear tooth top are joined, thereby can't realize self-locking near the planets of the five equilibrium gear clearances of loosing.When skidding appears in single driven wheel, because the increase of instantaneous acceleration, the friction that the brake shoe that makes inertia braking take turns acts on the diffusing gear outer shaft of planet increases, make unloaded fan-shaped bevel gear skew that the gap spring floats and join with the fan-shaped bevel gear of load, make two angles approaching, the addition summation is extruded into a self-locking gap near 1/2nd fixing tooth distances near the gap assembly of 1/2nd fixing tooth distances; After the tooth top spill cambered surface of tooth top convex globoidal between the gap and differential gear was joined, the differential gear that the tooth top cambered surface is joined drove the driving wheel of differential mechanism both sides just by unidirectional locking simultaneously; After the releasing of skidding, under the effect of driving wheel differential torsion, slippage or the separation on the spill cambered surface of differential gear tooth top of the tooth top convex globoidal of the fan-shaped bevel gear that joins floated unloaded fan-shaped bevel gear, realizes the automatic unlocking of differential mechanism.So it is little that diffusing tooth differential mechanism of the present invention has running resistance, the characteristics that the self-locking locking coefficient is big.
Other details of diffusing tooth differential mechanism of the present invention and characteristics can just can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings.
