Abstract
A novel vehicle hydraulic anti-theft lock comprises a lock casing consisting of a hydraulic valve and a valve cover. A hydraulic chamber, an oil inlet port, an oil outlet port and a guide key are arranged inside the hydraulic valve; a spiral screw mandrel is installed between the hydraulic valve and the valve cover for conducting screw transmission with a screw nut, a guide slot is formed on the screw nut to match with the guide key, and the screw nut conducts translational movement on the guide key when the spiral screw mandrel rotates; a valve spool is arranged inside the hydraulic chamber and is in threaded connection with the screw nut, resulting in translational movement with the screw nut; and a seal ring is arranged on the valve spool and allows a hydraulic oil circuit to generate a pressure force to lock vehicle wheels when the valve spool moves; and a travel switch is installed on the valve cover for limiting the movement position of the valve spool. The vehicle hydraulic anti-theft lock can be installed on any vehicles with hydraulic braking in a hidden way, which is implemented by disconnecting the original hydraulic braking oil pipe of the vehicle, connecting one end of the hydraulic braking oil pipe with the oil inlet port of the hydraulic anti-theft lock, and connecting a disk brake at the other end thereof with the oil pipe and then connecting with the outlet port of the hydraulic anti-theft lock.
Description
Technical field
The utility model relates to a kind of anti-theft column lock, especially is applicable to the vehicle with hydraulic brake system, plays antitheft effect.
Background technology
Before the utility model was made, existing antitheft hydraulic lock was to have utilized the check valve principle, and under anti-theft state, spring promotes spool and closes hydraulic valve, made the hydraulic oil can only nonreturn flow, and behind the apply the brakes device, hydraulic oil can be locked and make wheel braking.But the antitheft hydraulic lock of check valve principle must could play brake action using under the prerequisite of brake gear, is not that easily under the situation that does not have the apply the brakes device, anti-theft column lock can not play brake action in the use, and vehicle still can be pushed away.
Summary of the invention
The utility model proposes a kind of new vehicle antitheft hydraulic lock, can guarantee under anti-theft state that not the apply the brakes device also can permanently effective brake wheel, reach antitheft purpose.This device can be used with the electronic telecontrol Car Burglar Alarm of routine, and is easy and simple to handle, can be applied to such as: automobile, motor bike etc. has the vehicle of hydraulic brake system.
Main solution of the present utility model is: increase a hydraulic valve in the hydraulic braking oil circuit, oil inlet and oil outlet are arranged on the hydraulic valve, when making vehicle be in anti-theft state, electronic telecontrol Car Burglar Alarm control motor just changes, driving gear is arranged on the motor output shaft, driven gear is arranged on the helical screw, the gear meshing transmission is rotated helical screw, the nut moving linearly on the helical screw, and nut and spool link together, promoting the spool straight line moves, seal ring is arranged on the spool, being communicated with between the mobile cut-out oil inlet of spool and the oil outlet, and exert pressure to oil outlet, make the hydraulic brake system brake wheel, realize antitheft effect.When the anti-theft state of wanting freeing vehicle, the counter-rotating of electronic telecontrol Car Burglar Alarm control motor oppositely moves spool through aforesaid transmission device, and oil inlet is communicated with oil outlet, and it is unimpeded that the hydraulic braking oil circuit keeps.The utility model all can make spool realize the actv. self-locking under antitheft and the antitheft two states of releasing, and is safe and reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an A-A cutaway view of the present utility model.
Fig. 2 is the B-B view that removes the body cap part.
Fig. 3 is the nut part front view.
The specific embodiment
The lock body shell of the utility model vehicle hydraulic anti-theft column lock is made up of hydraulic valve (1) and body cap (4), hydraulic cavities (17), oil inlet (15) and oil outlet (16), feather key (18) are arranged in the hydraulic valve (1), the driving gear (13) of packing on DC machine (12), the motor output shaft is installed in the hydraulic valve (1); Helical screw (3) is installed between hydraulic valve (1) and the body cap (4), carry out worm drive with nut (6), be inserted in sliding shaft sleeve (2) and sliding shaft sleeve (8) at helical screw (3) two ends, pack on the helical screw (3) driven gear (14) and driving gear (13) engaged transmission; Have guide groove (19) to match with feather key (18) on the nut (6), when helical screw (3) rotated, nut (6) moved as straight line on feather key (18); The spool (11) of packing in the hydraulic cavities (17), spool (11) and nut (6) can be followed nut (6) and move as straight line by being threaded togather; Go up installation seal ring (9) and seal ring (10) at spool (11), seal ring (9) makes the oil circuit that connects oil outlet (16) produce hydraulic coupling, and seal ring (10) can not leak the hydraulic oil that connects oil inlet (15); Body cap (4) is gone up travel switch (5) and travel switch (7) is installed, and is used to limit the shift position of nut (6), has also promptly limited the shift position of spool (11).
The utility model can hidden installation on vehicle, the vehicle of all genus hydraulic brakings can be equipped this product, and the moving oil pipe of vehicle stoste compacting is disconnected, one termination oil inlet of the present utility model, the disc brake apparatus of the other end are connected with oil outlet of the present utility model behind the adjunction oil pipe.According to the quantity and the version that connect disc brake, hydraulic cavities, oil inlet and the oil outlet of the utility model vehicle hydraulic anti-joyride device can be arranged to one to four.
