Abstract

The utility model relates to a safety anti-collision braking device for vehicles, which comprises a telescopic bumper, a braking system and an anti-collision mechanism, which comprises a telescopic bumper, a braking system and an anti-collision mechanism, wherein, the anti-collision mechanism is connected to the front of the bumper, and is composed of a guide sleeve, a spring and an anti-collision frame; a spring is arranged between the anti-collision frame and the bumper; a guide sleeve is arranged in the spring. When motor vehicles generate collision under normal condition, the safety anti-collision braking device can automatically insure brake with favorable anti-collision and braking effect.

Description

The crashproof brake gear of automobile-used insurance

The utility model relates to the crashproof brake gear of a kind of automobile-used insurance, mainly insures the usefulness of brake for anticollision of motor vehicles.

Existing brake gear is that brake system 16 is seen Fig. 5.Brake wheel 8 is fixed on the wheel hub, together rotates with vehicle wheels.On fixing non-rotary back-plate 11, two rest pins 12 are arranged, the lower end of supporting and articulated brake shoe brake cheek 10.Friction lining 9 for brake usefulness is housed on the brake shoe brake cheek.Hydraulic braking wheel cylinder 6 also is housed on the back-plate 11, is connected with hydraulic brake master 4 on being contained in vehicle frame with oil pipe 5.Piston 3 in the master cylinder can be stepped on brake pedal 1 by the chaufeur pin and handle by push rod 2.Piece number 7 is a wheelcylinder piston.During brake, foot pedal drives master cylinder piston 3 by push rod 2, makes the master cylinder inner fluid flow into brake wheel cylinder 6 under certain pressure.And promote two brake shoe brake cheek 10 by two wheelcylinder pistons 7 and rotate around rest pin 12, the upper end separately and together with friction lining 9 is pressed on the brake wheel 8 to realize brake to both sides.When decontroling brake pedal, pull back spring 13 retracts original position with brake shoe brake cheek, to remove brake.Its weak point is: can only brake by chaufeur, realize self-actuating brake in the time of can not finishing self-propelled vehicle and hit to obstacle.

A kind of crashproof brake gear of automobile-used insurance of automatic collision and brake when bump occurring in self-propelled vehicle the place ahead but being to overcome above-mentioned weak point of the prior art, the purpose of this utility model is provided.

The purpose of this utility model can reach by following measure: the utility model is made up of expansion bumper, brake system and anticollision mechanism, be connected with anticollision mechanism before the expansion bumper, form by orienting sleeve, spring and bumper frame, between bumper frame and the expansion bumper spring is housed, orienting sleeve is arranged in the spring.

On the brake wheel of brake system tooth is arranged.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the planar view of the utility model on self-propelled vehicle;

Fig. 2 is the enlarged view of the B of Fig. 1 to half-twist;

Fig. 3 for the C of Fig. 1 to A portion overlook enlarged drawing, mainly represent the structure of brake system;

Fig. 4 for Fig. 3 A portion overlook enlarged drawing;

Fig. 5 is the figure of existing brake gear.

The accompanying drawing piece number of prior art is represented:

1, brake pedal 2, push rod 3, master cylinder piston 4, master brake cylinder

5, oil pipe 6, brake wheel cylinder 7, wheelcylinder piston 8, brake wheel

9, friction lining 10, brake shoe brake cheek 11, back-plate 12, rest pin

13, pull back spring 14, expansion bumper 15, self-propelled vehicle 16, brake system

17, bearing pin 18, expansion link 19, fork arm 20, bearing pin

Accompanying drawing piece number of the present utility model is represented:

21, orienting sleeve 22, spring 23, bumper frame

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing:

Fig. 1-Fig. 3 mainly represents structure of the present utility model, form by expansion bumper, brake system and anticollision mechanism, anticollision mechanism comprises orienting sleeve 21, spring 22 and bumper frame 23, and solid welding has the orienting sleeve 21 in spring and the spring on the expansion bumper, spring front end and bumper frame welding.In order to strengthen the brake reliability, in brake wheel, have additional tooth.

Be connected with expansion link 18 behind the expansion bumper of Fig. 3 and Fig. 4 prior art, there is fork arm 19 the expansion link rear end, and is porose on the fork arm, and bearing pin 20 penetrates fork arm hole and brake pedal 1 and push rod 2 is hinged with the fork arm 19 of expansion link.

During use,, step on brake pedal by the chaufeur pin and realize in the brake of self-propelled vehicle cruising.When accident to occur be obstacle before bumper frame strikes self-propelled vehicle, play earlier buffering, insurance and crashproof effect, simultaneously, expansion bumper slides backward, drive push rod to finish brake, owing to have additional tooth in the brake wheel, braking distance can shorten greatly, braking effect is good, has played the automatically reliable braking action that occurs under the accident conditions.

The utility model contrast prior art has following advantage:

When occurring the bump obstacle under the motor vehicle normal condition, but voluntary insurance is crashproof and the good brake of braking effect.

Claims

1, the crashproof brake gear of a kind of automobile-used insurance comprises expansion bumper and brake system, it is characterized in that, also comprise anticollision mechanism, be connected with anticollision mechanism before the expansion bumper, form by orienting sleeve, spring and bumper frame, between bumper frame and the expansion bumper spring is housed, orienting sleeve is arranged in the spring.

2, the crashproof brake gear of automobile-used insurance according to claim 1 is characterized in that on the brake wheel of brake system tooth being arranged.
