SU794538A1 - Device for indicating maximum braking of motor vehicle - Google Patents

Description

one

The invention relates to the field of measuring motion parameters of moving objects, in particular, to vehicle acceleration (deceleration) meters.

Acceleration (retardation) meters are known, which contain a ball inertial mass placed in an inclined tube with electrical contacts. At a certain amount of acceleration (deceleration), the inertial mass closes the electrical contacts and turns on the indicator 1.

A disadvantage of the known device is the short indication time with decreasing acceleration after the response of the meter.

To increase the display time, various devices are usually used, for example, a relay with a delay of 2. The disadvantage of such devices is their complexity.

The purpose of the invention is to simplify the device while increasing the time of visual indication.

For this purpose, the tubular chamber at a distance of at least 1/3 of the length from the upper end is bent downwards.

The drawing shows the structural diagram of the device.

The device contains a tube 1 with lower and upper rubber stoppers 2, 3 and a ball 4. The lower stopper 2 is provided with a tab with a hole through which it is attached to the axis 5 of the bracket 6. The upper stopper 3 is made with two contacts 7

and 8 of the electrical signal circuit 9 and has a tab with an opening for a latch 10 inserted into one of the holes 11 of the bracket 6. The bracket is mounted in the cab of the vehicle in an upright

position, with the tube in the direction of travel. For this purpose, the holes 12 and 13 in the bracket are used. The tube 1 at a distance Va from its upper end is made downward. The holes on the bracket 6 provide with the help of the clamp 10 the possibility of changing the inclination of the tube 1 and changing the fixed value of the maximum deceleration when braking

vehicle such as a car.

Contacts 7 and 8 are connected by means of a switch 14 to the warning light 15 in the driver’s cab and the warning lights of the parking lights 16 located at the front and rear of the vehicle.

The device works as follows. Depending on the type of transport

means such as cars or trucks
