Description

Spiketooth type self-propelled vehicle emergency brake

The utility model belongs to a kind of vehicle brake device, specifically a kind of a kind of brake shovel with spike-tooth is inserted brake gear between the ground that wheel is in contact with it.

The brake of motor-driven vehicle device generally adopts brake disc mechanism to make the wheel of rotation be subjected to an opposing torque that stops its rotation, because the effect of car body powerful inertia, after the emergency brake, braking mark is still very long, particularly for ice and snow, rainwater road surface, braking distance also can be longer.

The purpose of this utility model is to disclose a kind of brake principle brand new spiketooth type self-propelled vehicle emergency brake, has brake principle novelty, braking effect is fabulous, and is special in the better advantage of smooth ice and snow road effect, can be used for all self-propelled vehiclees.

The principle of the utility model brake is the brake shovel that one of design has the rigidity finger under the car body chassis, drives the brake shovel by alighting gear and extend between wheel and the ground, and finger thrusts the road surface, plays the friction force effect that strengthens.

Its composition of the utility model comprises:

1, at least one spiketooth type brake shovel, respectively there is an anti-sideskid both sides of shovel.Side sheet room is apart from wide greater than tire, and the horizontal of shovel taken advantage of down a plurality of and rigidity pyramid type finger or four stupefied pointed spike-tooths its one.

2, each spiketooth type brake shovel correspondence is equipped with at least one sleeve-type alighting gear, and its operating bar is connected with the shovel front end, can do to extend and pack up action, makes between brake shovel insertion or separating wheel and the ground, and its urceolus connects with car body.

3, also has one group of actuating device that makes the action of sleeve-type alighting gear.

Enforcement of the present utility model can also be the additional scheme that following feature is arranged.

The utility model is applied to full size vehicle, spike-tooth brake shovel and sleeve-type alighting gear can be for being the bowline on a bight structure, be respectively applied for the brake of two trailing wheels, gear up and to put down be that combination by a motor-driven long lead screw and screw realizes, motor is fixed under the car body long lead screw and drives screw and seesaw, one is connected with the brake shovel respectively with the transverse axis two ends of screw one, and screw is mobile before and after on leading screw, drives two alighting gear operating bars and packs up synchronously or put down.It is at every group of spiketooth type brake shovel balancing device to be housed that this programme further improves, and moving bar that can only longitudinal extension in tube joins with the brake shovel, and outer cylinder body is connected with car body.For stable brake shovel, guarantee that its folding and unfolding is reliable, the sleeve-type alighting gear can be designed as two one group, arranges in the shovel both sides of braking respectively, respectively adorns a stabilizer bracket of placing the brake shovel under the car body that is stopped after the brake shovel is packed up.

The utility model is used for single-wheel when brake, as is used for motor bike, and sleeve-type alighting gear urceolus wherein vertically cracks in the tube, and extension spring is equipped with at the throw rod top, and the driving of its throw rod connects alighting gear throw rod and pedal realization by lacing wire.

The simpler embodiment of the utility model is: the described sleeve-type frame that falls can adopt pneumatic or hydraulic actuation is simple, realizes that by cylinder or hydraulic ram gear up puts down.

During the utility model brake, will be gear down, the shovel that will brake is pushed into and is pressed in the middle of rear tyre and the ground, rigidity wedge angle pinning is gone into ground, and car body is produced very big friction drag, especially for ice and snow road, braking effect is better, on average can shorten braking distance 50-70%, and be difficult for produce owing to the emergency brake car causes car body and fall consequence, can effectively avoid traffic accident.

The plane of the embodiment step was put figure when accompanying drawing 1 was used for automobile for the utility model:

Accompanying drawing 2 is Fig. 1 braking state figure:

Accompanying drawing 3 is Fig. 1 collapsed state figure:

Embodiment schematic diagram of movements when accompanying drawing 4 is used for motor bike for the utility model.

Fig. 1-Fig. 3 is the brake that is used for automobile, the outer cylinder body of motor 1, left and right sides balancing device 2 (3) and alighting gear 4 all is contained under the car body chassis among the figure, and their throw rod all is connected with cooresponding brake shovel 7, long lead screw 5 is driven with screw 6 by motor shaft with screw 6 and moves forward and backward for the transverse axis 8 of one, the transverse axis two ends are connected with the brake shovel respectively, thereby brake shovel and alighting gear move forward and backward and make the brake shovel to lift or put down with screw synchronously, is in braking state and disengaging braking state respectively.Just in time be placed on the stabilizer bracket 9 after the brake shovel is packed up as can be seen from Figure 3.Sleeve-type alighting gear among Fig. 1 can be designed to two one group arranged side by side, thereby improves the stable property examined of brake process.Be the embodiment that is applied to motor bike single-wheel brake among Fig. 4, sleeve-type alighting gear urceolus has one vertically to crack 10, adorns an extension spring 11 in the sleeve and makes the throw rod return that stretches out, stretcher 12 is through lacing wire 13, throw rod is stretched out, put down the brake shovel, thereby make the car body stop motion.

If adopt the pneumatic or hydraulic actuation that can move voluntarily simple from the sleeve-type alighting gear 4 of Fig. 1-Fig. 4, structure will be more simple.

The utility model adopts the brake principle of novel concept, and its technique effect is very remarkable.
