Abstract

The utility model provides a secondary brake for vehicles, relating to the brake technique. The utility model comprises a double-hole seat, a connector installed on the double-hole seat, a cylinder head connected with the connector into a whole, a cylinder body screwed on the cylinder head, a vertical axis in the cylinder body, a piston fixed to the vertical axis, a spring sheathed on the vertical axis, a tube communicated with the cylinder body, a connection seat is screwed at lower end of the vertical axis, a simple-hole seat installed on the connection seat through an axis, a suction bowl and a one-way valve installed on the simple hole seat, an exhaust tube which is installed on the simple hole seat and is communicated with the suction bowl, and sliding valves installed on the tube and the exhaust tube. The utility model has the advantages that the sliding distance of the vehicles can be reduces, accidents are reduced and the abrasion of vehicle tyre is reduced.

Description

Secondary brake for vehicles

The utility model belongs to the technical field of drg.

At present braking automobile all is with wheel braking, utilizes wheel tyre and ground-surface friction drag that car is stopped, but such tire and road surface acutely rub, and tire is fragile, and the car coasting distance is long.

The purpose of this utility model provides a kind of additional brake, makes it when brake, and the resistance between car and ground is increased, and reduces coasting distance, reduces the abrasion of tire.

This automobile-used additional brake, comprise the diplopore seat, be contained in the axle on the diplopore seat, be contained in the joint which is provided with the hole on the axle, also comprise the cylinder cap that is connected as a single entity with joint, be screwed in the cylinder body on the cylinder cap, the vertical pivot which is provided with bulge loop of cylinder body bottom surface and cylinder cap is stretched out at two ends respectively in cylinder body, at the piston of cylinder body internal fixation on vertical pivot, be enclosed within the spring on the vertical pivot between cylinder body bottom surface and piston, the pipe that is communicated with cylinder body is screwed in the seated of vertical pivot lower end, be contained in the adapter shaft on the seated, be contained in the single hole seat on the adapter shaft, be contained in the suction bowl on the single hole seat, be screwed in a check valve that is communicated with the suction bowl on the single hole seat, be contained in a freeing pipe that is communicated with the suction bowl on the single hole seat, be contained in the guiding valve on pipe and the freeing pipe.

When brake, gas enters cylinder body by guiding valve and pipe, promotes piston and moves downward, and makes and inhales firm being adsorbed on the road surface of bowl, thereby strengthen braking force, and the distance that car is slided shortens, and reduces the abrasion of tire, the generation of minimizing accident.

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure 1 shows that the front elevation of automobile-used additional brake;

Figure 2 shows that the left view of automobile-used additional brake;

Automobile-used additional brake as shown in the figure, comprise two diplopore seats (1), be contained in two axles (2) in diplopore seat (1) hole respectively, what which is provided with the hole is contained in two joints (3) of axle on (2) respectively, the round cylinder cap (4) that is connected as a single entity with joint (3), be screwed in the tubbiness cylinder body (5) on the cylinder cap (4), two ends are stretched out cylinder cap (4) respectively and are put in the hole of joint (3) and two vertical pivots (6) that cylinder body (5) bottom surface which is provided with bulge loop in cylinder body (5) respectively, in cylinder body (5), be separately fixed at vertical pivot (6) and go up the two-piston (7) on bulge loop top, in cylinder body (5), be enclosed within two springs (8) on two vertical pivots (6) respectively, two pipes (9) that are communicated with cylinder body (5) on piston (7) top, be screwed in two seateds (10) of vertical pivot (6) lower end respectively, be contained in the adapter shaft (11) on two seateds (10), be contained in the inverted T-shaped single hole seat (12) on the adapter shaft (11), the rubber truncated cone-shaped that pressure is bonded on the single hole seat (12) is inhaled bowl (13), be screwed in the non return valve for outflow (14) that single hole seat (12) is gone up and suction bowl (13) is communicated with, be contained in the freeing pipe (15) that single hole seat (12) is gone up and suction bowl (13) is communicated with, be contained in the two-position four-way guiding valve (16) on pipe (9) and the freeing pipe (15).

During brake, guiding valve is opened, and gas enters cylinder body by pipe, the promotion piston moves downward, to inhale bowl and press to the road surface, the gas of inhaling in the bowl is discharged by check valve, inhales firm being adsorbed on the road surface of bowl, during startup, close guiding valve, the gas in the nullisomic enters the suction bowl by pipe through guiding valve and freeing pipe, makes the suction bowl break away from the road surface, under the effect of spring, make and inhale the bowl rise simultaneously.This automobile-used additional brake also can be used as jack and uses.

Claims

1, a kind of automobile-used additional brake, comprise diplopore seat (1), be contained in the axle (2) on the diplopore seat (1), be contained in the joint (3) which is provided with the hole on the axle (2), it is characterized in that also comprising the cylinder cap (4) that is connected as a single entity with joint (3), be screwed in the cylinder body (5) on the cylinder cap (4), the vertical pivot which is provided with bulge loop (6) of cylinder body (5) bottom surface and cylinder cap (4) is stretched out at two ends respectively in cylinder body (5), at the piston (7) of cylinder body (5) internal fixation on vertical pivot (6), between cylinder body (5) bottom surface and piston (7), be enclosed within the spring (8) on the vertical pivot (6), the pipe (9) that is communicated with cylinder body (5), be screwed in the seated (10) of vertical pivot (6) lower end, be contained in the adapter shaft (11) on the seated (10), be contained in the single hole seat (12) on the adapter shaft (11), be contained in the suction bowl (13) on the single hole seat (12), be screwed in the check valve (14) that single hole seat (12) is gone up and the suction bowl is communicated with, be contained in the freeing pipe (15) that single hole seat (12) is gone up and suction bowl (13) is communicated with, be contained in the guiding valve (16) on pipe (9) and the freeing pipe (15).

2, automobile-used additional brake according to claim 1 is characterized in that guiding valve (16) is the two-position four-way guiding valve.
