Abstract
The invention discloses a mechanical lock type differential mechanism. A shifting fork (3) moves on a sliding rod (7) along a tension direction by pulling an operating rope (15), and presses a spring (8) during moving so as to drive a crankset (2) to be meshed with another crankset (1); and therefore, a differential mechanism gear half shaft (17) is rigidly connected with the differential mechanism, so that the differential mechanism is locked.
Description
Technical field:
The present invention relates to a kind of mechanical locking differential of manually operated pure machinery.
Background technique:
Differential mechanism divides three types at present: open differential, limited-slip differential, locking differential.The present invention is a locking differential.Locking differential branch: automatically controlled locking differential, pneumatic locking differential, mechanical locking differential three major types.Automatically controlled locking differential is connected electromagnetic coil through switch activated circuit; Use electromagnetic force to drive diff lock and unblank and locking, pneumatic locking differential is connected the release of gas storage filling switch gear through switch activated circuit and is unblanked and locking through the gas-powered diff lock of air compressor compression.More than two kinds of locking differentials need to consume electricity, pressurized air as the energy that drives Locking Device reaching to open and close in the lock purpose process.
Summary of the invention:
Need the problem of additional energy source for solving existing locking differential as the driving force that drives Locking Device.The present invention provides a kind of mechanical locking differential, need not to use the energy as driving force, only needs manually-operable just can reach the purpose that complete locking is opened differential mechanism.
The technical solution adopted for the present invention to solve the technical problems is:
This mechanical locking differential is to make differential mechanism be connected the purpose that reaches locking differential with differential gear semiaxis rigidity.It is to accomplish through jaw clutch that differential carrier is connected with the rigidity of differential gear semiaxis.Jaw clutch is made up of chain wheel (1) and chain wheel (2), and chain wheel (1) is an one with differential carrier, and chain wheel (2) is formed the free-sliding spline pair with a side differential gear semiaxis.Slide bar (7) is parallel to differential gear semiaxis (17) and forms mobile linear guide pairs with fork (3) and spring (8), and the two ends of slide bar are separately fixed in the hole (10) of hole of axle housing (9) and differential case bearing bracket.Sheave block is installed on the axle housing, and manipulating pulling cable (15) one ends are connected with fork (3) through pulley (12) guiding.Pulling manipulating pulling cable (15) makes fork (3) on slide bar (7), prolong direction of pull and moves, and extrusion spring in the moving process (8) drives chain wheel (2) and chain wheel (1) interlock, makes differential gear semiaxis (17) be connected the differential mechanism locking with the differential mechanism rigidity; Unclamp manipulating pulling cable (15), fork (3) is resetted, drive chain wheel (2) and separate the differential mechanism release with chain wheel (1).
The invention has the beneficial effects as follows: manual locking release differential mechanism, drive the lockable mechanism action without any need for the extra energy as driving force, simple in structure, compact.
