(57) Abstract:Usage: on vehicles to improve the adhesion of the wheels during braking. The inventive device has an axle 1, is connected to the hub 2 of the wheel, the wheel disc and the face-plate 5 mounted on the axis 1 with the possibility of angular displacement relative to the wheel, spring-loaded pins 13 mounted in the guide rails 14 and extension mechanism pins, made in the form of Cams 9 kinematically connected to the faceplate by means of the fingers 3, located in the annular grooves 4 of the disk. When braking overcome the holding force of the spring, whereupon the radial tear, the fist pushes the pins out of the guides and they come into contact with the surface of the highway. 3 Il. The invention relates to devices improve the adhesion of the wheels during braking and can be used in the event of an emergency or bad state highways, for example, when icy or wet highways.Technical solution can be used for any type of object that uses wheels (vehicles, aircraft, and so on).Known devices that powysian ledges, attached to the drive wheel (see ed. mon. N 66596, class B 60 C 27/20, 1946).The main disadvantage to be considered in increased wear of the protrusions with the loss of braking effectiveness on an emergency site thoroughfares.Known brake device of the vehicle, including the axis, connected with the wheel hub, the wheel disc and the faceplate installed with the possibility of relative angular displacement relative to the hub, the pins are made with the possibility of extension in the radial direction through the mechanism of the extension (see U.S. patent N 2174944, CL 301-47, 1939)
Extension mechanism pins made in the form of rotatable relative to the hub with the axis of the faceplate, which results in the movement of the kinematic pair: chain-star-worm pair-screw pair with a sliding pin on the key.The disadvantages of the known technical solutions should be considered as a complex kinematic relationship for the nomination of pins, that all the elements of the kinematic chain are in the hardest working conditions both in the atmosphere and pollution that dirt road immediately will destroy all the braking unit.Worm pair made somatostatine conclusion: the well-known technological solution undependable, it is difficult and inefficient for polluted thoroughfares.The proposal is aimed at solving such technical problems such as increase reliability, simplify design, increase efficiency in any state highways.This technical result is achieved by the fact that the mechanism of extension pins made in the form of Cams, kinematically connected to the faceplate by means of fingers located in the grooves of the drive wheel and is provided to hold the end position at the end of the groove by a spring, one end of the fixed finger and the other on the wheel.In Fig. 1 shows a section through the axis of the wheel; Fig. 2 section A-A in Fig. 1; Fig. 3 cross-section B-B of Fig. 1.The brake device of the vehicle includes an axle 1, which is connected to the drive and brake the vehicle. Axis 1 is fixed to the hub 2 of the wheel with the fingers 3, which pass through the slots 4, made in the faceplate 5 wheels. Drive with faceplate 5 is installed on axis 1 wheels with the possibility of angular displacement by means of the sleeve 6. On the drive with faceplate 5 is fixed rim 7 camera 8 on it. The grooves 4 are made of curly and allow the fingers 3 to move in napaimiut pins 12 with the tabs 13. Themselves pins 12 are placed in the guide rails 14 mounted on the cylindrical part of the drive with faceplate 5 and the fingers 3 are connected with a spring 15 with the face-plate 5 through the adjusting device 16 screw type.Extension mechanism pins 12 includes fingers 3, the Cam 9 and the faceplate 5. Faceplate 5 disc cover all the mechanical part of the braking device, and the grooves 4 and the guides 14 must have a seal.Operates the brake device of the vehicle as follows.During normal operation of the vehicle when the vehicle line has good adhesion, transport stop is the brake of the vehicle and the spring 15 does not allow relative angular displacement of the gear disc 5 relative to the axis 1. When braking, the force of the spring 15 is overcome, is the relative angular displacement of the disk and table 5, the pins 12 slide on the profile 10 of the Cam 9 and moved their projections 13 to contact with the highway, cutting into its surface to stop the vehicle, then due to the spring 15 will occur a reverse rotation to the stop finger 3 in the end surface of the grooves 4 with minor tgpy 13 can be made of various types, depending on the type of vehicle (pointed, in the form of shovels and so on).Adjustment of the springs 15 is produced as wear of the projections in the form of highways. For driving on icy surface of the spring 15 must be loosened to output pins 12 at the slightest braking force. A braking device must be installed on the rear wheels to the center of gravity was at the front of the brake devices and their effort did not lead to loss of control. Installation on the front wheels is solved for the particular case, for example, at different force on the springs 15 on the front (reinforced) and rear wheels (weakened).When installing brakes on the front and rear wheels and symmetrical execution of the projections 13, the deceleration will be performed and when the slide back.Equivalent technical solution can be fixed in the angular direction of the faceplate with the disc 5 with axis 1, and movable in an angular direction to the installation of the hub 2. The brake device of the vehicle, including the axis, connected with the wheel hub, the wheel disc and the faceplate installed on axis with the possibility of relative angular displacement otonositelno angular movement of the wheel and the gear mechanism, extension wherein the extension mechanism is made in the form of Cams, kinematically connected to the faceplate by means of fingers located in the annular grooves of the drive wheel and is provided to hold the end position at the end of the groove by a spring, one end of the fixed finger and the other on the wheel.
