Description
Technical field
The present invention relates to differential art field, particularly a kind of mechanical lock-type differential.
Background technology
In pure mechanical differential gear box, common open type differential cannot continue to move in the situation that single wheel skids or be unsettled at all, must rely on external force to pull just and can get rid of poverty.
Eton differential mechanism adopts mechanical lock, when single wheel skids or is unsettled, when the speed discrepancy of two-wheeled reaches certain numerical value, mechanical lock works two semiaxis is locked together, drive vehicle advance or retreat, power is transported to the wheel of effective adherence ground completely, but the locking of differential mechanism needs certain reaction time.
Torsen differential mechanism (limited-slip differential) is controlled in certain scope the speed discrepancy between two-wheeled by the effect of turbine, worm screw, be unlikely to occur skidding or the unsettled phenomenon that makes vehicle advance or to retreat because of single wheel, but this can not flow to power the effectively wheel of adherence ground completely, and the wheel that part power is skidded has consumed.
Open type differential cannot provide the power that advances or retreat to vehicle in the time that single wheel skids or be unsettled, causes vehicle to move.
Eton mechanical lock-type differential, structure relative complex cost is high, and its latch functions needs certain reaction time.
Torsen differential mechanism cost is high, and power can not be transported to the wheel of effective adherence ground completely.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of pure frame for movement, structure is relatively simple, performance latch functions mechanical lock-type differential rapidly.
The technical solution adopted in the present invention is: a kind of mechanical lock-type differential, comprise housing and a left side, right axle shaft, left, right axle shaft puts in housing, described housing is provided with and a left side, the side cover of right axle shaft socket, in housing, be provided with and a left side, the ratchet assembly that right axle shaft connects, described ratchet assembly comprises outer ratchet group and handle ratchet wheel group, described outer ratchet group is made up of two ratchets that movably teeth are contrary of mutually pegging graft, be divided into left outside ratchet and right outside ratchet, described handle ratchet wheel group is made up of two ratchets that movably teeth are contrary of mutually pegging graft, be divided into left inside ratchet and right inside ratchet, described left outside ratchet is fixedly connected with right inside ratchet, described right outside ratchet is fixedly connected with left inside ratchet, described handle ratchet wheel group entirety is nested in outer ratchet group, the teeth opposite direction of left outside ratchet and left inside ratchet, the teeth opposite direction of right outside ratchet and right inside ratchet.
Further, on described left outside ratchet and right outside ratchet, respectively there are two inclined holes, in inclined hole, are inserted with the bearing pin fixing with differential mechanism shell.
Further, the side cover of described left and right half inner side is fixed with and the ratchet that is connected with dual layer opposite teeth of the inside and outside ratchet phase of ratchet assembly interlock.
Further, described connection ratchet is slidably fixed on a left side by spline, on right axle shaft.
Further, in described left and right half, connect between ratchet and side cover and be provided with spring.
Compared with prior art, the invention has the beneficial effects as follows: the ratchet mechanism that adopts four groups of improveds, in the time advancing, retreat, there are respectively two groups of ratchet mechanisms to work, realize the mutual switching between inside and outside ratchet mechanism by the pressure of the slight rotation of power transmission shaft and spring, and the braking action of engine still exists, pure frame for movement, structure is relatively simple, and performance latch functions is rapid.
