Abstract

A parking brake and anti-theft apparatus as described herein may include a brake assembly, a linear actuator and a plurality of locking pins. The brake assembly may include a rotor plate. The rotor plate may include a plurality of openings in and/or through the rotor plate. The plurality of locking pins may be extendable by the linear actuator. The pins may be aligned perpendicular to a face of the rotor plate such that, as at least one of the pins is disposed over one of the plurality of openings and the actuator extends the plurality of locking pins, the pin disposed over the one of the plurality of openings passes into the one of the plurality of openings. In various embodiments, the plurality of pins may comprise a length equal to or greater than a length between two adjacent openings of the plurality of openings.

Claims

1. A vehicle parking brake and anti-theft apparatus, comprising:

a brake assembly comprising a rotor plate, the rotor plate comprising a plurality of openings through the rotor plate; and

a plurality of locking pins, each locking pin having a corresponding linear actuator, wherein each locking pin is extendable from the corresponding linear actuator, the pins aligned perpendicular to a circular face of the rotor plate such that, as at least one of the pins is disposed over one of the plurality of openings and the linear actuator extends locking pin disposed over the one of the plurality of openings, the pin disposed over the one of the plurality of openings extends from the linear actuator and passes into the one of the plurality of openings,

wherein the plurality of pins comprise a length extending from a first of the pins to a last of the pins, the length equal to or greater than a length between two adjacent openings.

2. The vehicle parking brake and anti-theft apparatus of claim 1, wherein the openings are disposed in a circular pattern concentric with the rotor plate circumference.

3. The vehicle parking brake and anti-theft apparatus of claim 2, wherein the plurality of pins are aligned along the circular pattern.

4. The vehicle parking brake and anti-theft apparatus of claim 1, wherein the openings are aligned along a radius of the rotor plate.

5. The vehicle parking brake and anti-theft apparatus of claim 4, wherein the plurality of pins are aligned along the radius.

6. The vehicle parking brake and anti-theft apparatus of claim 1, wherein the openings are aligned along a chord of the rotor plate.

7. The vehicle parking brake and anti-theft apparatus of claim 6, wherein the chord is curved.

8. The vehicle parking brake and anti-theft apparatus of claim 6, wherein the plurality of pins are aligned along the chord.

9. The vehicle parking brake and anti-theft apparatus of claim 1, wherein one or more of the plurality of pins comprises a core and a lining, the lining having a hardness greater than a hardness of a material of the rotor plate.

10. The vehicle parking brake and anti-theft apparatus of claim 9, wherein the lining comprises one or more of tungsten carbide, titanium dioxide, diamond and silicon dioxide.

11. The vehicle parking brake and anti-theft apparatus of claim 1, wherein one or more of the pins comprises one or more of tungsten carbide, titanium dioxide, diamond and silicon dioxide.

12. A vehicle parking brake and anti-theft apparatus, comprising:

a brake assembly comprising a rotor plate, the rotor plate comprising a plurality of openings through the rotor plate; and

a plurality of locking pins, each locking pin having a corresponding linear actuator, wherein each locking pin is extendable from the corresponding linear actuator, the pins aligned perpendicular to a face of the rotor plate such that, as at least one of the pins is disposed over one of the plurality of openings and the actuator extends the plurality of locking pins, the pin disposed over the one of the plurality of openings passes into the one of the plurality of openings, wherein one or more of the plurality of pins comprises a freely-rolling ball tip.

13. The vehicle parking brake and anti-theft apparatus of claim 12, wherein the ball tip comprises a spherical removable insert.

14. The vehicle parking brake and anti-theft apparatus of claim 12, wherein the ball tip comprises a material having a hardness exceeding a hardness of the rotor plate.

15. The vehicle parking brake and anti-theft apparatus of claim 12, wherein the ball tip comprises one or more of tungsten carbide, titanium dioxide, diamond, and silicon dioxide.

16. A vehicle parking brake and anti-theft apparatus, comprising:

a brake assembly comprising a rotor plate, the rotor plate comprising a plurality of openings through the rotor plate; and

a plurality of locking pins, each locking pin having a corresponding linear actuator, wherein each locking pin is extendable from the corresponding linear actuator, the pins aligned perpendicular to a face of the rotor plate such that, as at least one of the pins is disposed over one of the plurality of openings and the actuator extends the plurality of locking pins, the pin disposed over the one of the plurality of openings passes into the one of the plurality of openings, wherein one or more of the openings comprises a hollow insert, the insert comprising a material different than a material of the rotor plate.

17. The vehicle parking brake and anti-theft apparatus of claim 16, wherein the insert is removable.

18. The vehicle parking brake and anti-theft apparatus of claim 16, wherein the insert material has a hardness greater than the rotor plate material.

19. The vehicle parking brake and anti-theft apparatus of claim 16, wherein the insert material comprises one or more of tungsten carbide, titanium dioxide, diamond, and silicon dioxide.
