Description

Field of technology

The invention relates to the field of motor vehicle engineering, in particular to additional braking devices designed to reduce the braking distance, especially when braking on a slippery road surface, and can be used in the event of failure of the main braking system of the vehicle, during a forced stop on an ascent or descent, on ice or other road situations, instead of wheel chocks.

State of the art

The prior art discloses an additional brake for a vehicle comprising a brake shoe located behind the rear axle, secured to a lever pivotally mounted by means of clamps on the rear axle, wherein the lever is kinematically connected to the rod of a working cylinder with a piston spring-loaded from below, characterized in that the brake shoe is made in the form of a wheel with a replaceable rim and is provided with brake discs with annular cylinders with heads in which annular pistons are located, wherein the wheel rim is provided with spherical protrusions made with the possibility of contacting the road surface, and the wheel axle is kinematically connected to the levers by means of the tails of the heads (see RU 2013247, 03/28/1991).

The disadvantages of this patent are the complexity and low reliability of the device, which will lead to a sharp turn of the car and an accident when braking.

Disclosure of invention

The technical result of the claimed invention is the creation of a simple and reliable additional braking device for emergency stopping of a vehicle.

The above technical result is achieved by an additional braking device for a car, which includes a control cable or a control electric element, located in the driver's cabin, a braking element and a latch-lock, by means of which the braking element is connected to the frame of the vehicle, wherein the braking element is at least one tread of a car tire, which is a cut strip from a car tire, equipped with spikes and connected through an iron fastening to a nylon tape cable, and the latch-lock is a housing with a rod with a spring placed in it, which are set in motion to the "on" position by the control cable or the control electric element for lowering the braking element under the wheel of the car for its emergency stop.

Fig. 4 shows a general schematic view of the installation and operation of the additional brake option according to option 1.

Fig. 5 shows a general schematic view of the installation and operation of the additional brake option according to option 2.

Fig. 6-8 shows the actual operating principle of the additional braking device.

Implementation of the invention

The declared additional braking device includes a control cable or a control electric element located in the driver's cabin, a braking element and a latch-lock.

The braking element is at least one tread of a car tire 1, which is a strip cut from a car tire, equipped with spikes, a hook 2 and connected via an iron fastening 3 to a nylon tape cable 4, and the latch-lock is a housing 5 with a rod 6 with a spring 7 placed in it.

The declared additional braking device works as follows.

The latch-lock is fixed on the frame 8 of the car and is in the "off" position. The brake element with the tread of the car tire is located on the fender 9 of the car, and with a nylon tape cable with the help of a hook 2 is hooked to the latch-lock rod.

When the latch-lock is “turned on” from the driver’s cabin, the rod with the spring moves in the latch-lock housing and the tire tread is lowered by its own weight and falls under the car wheel and is held between the wheel and the road surface by a nylon tape cable, the wheel is blocked until the car comes to a complete stop.

Moreover, the declared device can perform both a braking function and an anti-rollback function.

The number of cables depends on the vehicle's load capacity.

The applicant created a prototype of the claimed device, which showed good results in practice.

Claims (1)
