Shock stiffener system
Provided is an automatically controlled shock stiffening system. The automatically controlled shock stiffening system may include an electronic control unit receiving sensor input which automatically stiffens and softens a shock during operation. An override button is provided to immediately stiffen the shock in response to a user activating the override button. The system may include a main body with an oil flow aperture and a flow control system that operates to restrict the flow of oil between the reservoir and the shock. The automatically controlled shock stiffening system may be coupled between the reservoir and the bridge of the shock and operates to restrict flow of the oil in order to stiffen the shock immediately in response to activation of the override button.
1 . An automatically controlled shock stiffening system, comprising:
a main body configured to be coupled between a shock and an oil reservoir of an assembled hydraulic shock system of a vehicle;
a flow control system coupled to or integral to the main body and changeable between an engaged position, in which oil flow between the shock and the oil reservoir is restricted, and a disengaged position, in which oil flow between the shock and the oil reservoir is unrestricted;
an electronic control unit configured to be coupled to the vehicle;
a coupling coupled between the electronic control unit and the flow control system to establish communication between the electronic control unit and the flow control system, wherein the flow control system changes automatically between the engaged position and the disengaged position in response to operation of the electronic control unit;
at least one sensor coupled to the electronic control unit, wherein the at least one sensor provides input relative to operation of the vehicle; and
an override button coupled to the vehicle within a driver compartment of the vehicle, wherein the override button is coupled to a control module positioned between the electronic control unit and the flow control system, and wherein the control module is programmed to interrupt control of the electronic control unit without causing the electronic control unit to register a sensor error or malfunction causing the vehicle to go into limp mode.
2 . The system of claim 1 , wherein the flow control system comprises:
at least one oil flow aperture through the main body, the at least one oil flow aperture being in fluid communication with the shock and the oil reservoir;
a channel through the main body;
a plunger slidingly coupled within the channel, wherein the plunger is changeable from an engaged position, in which the plunger is positioned to block the oil flow aperture so as to restrict oil flow through the oil flow aperture, and a disengaged position, in which the plunger is positioned away from the oil flow aperture so as to allow unrestricted oil flow through the oil flow aperture; and
a solenoid coupled between the plunger and the coupling, wherein the plunger is changed between the engaged position and the disengaged position in response to engagement and disengagement of the solenoid in response to operation of the electronic control unit.
3 . The system of claim 2 , further comprising at least one bypass aperture through the main body, the at least one bypass aperture being in fluid communication with the shock and the oil reservoir, wherein oil flows through the at least one bypass aperture in response to a predetermined minimum oil pressure differential between a bridge and the oil reservoir.
4 . The system of claim 3 , wherein the bridge is coupled between the shock and the main body, the bridge being in fluid communication with the shock and the main body.
5 . The system of claim 1 , wherein the at least one sensor is a throttle sensor.
6 . The system of claim 1 , wherein the at least one sensor is a brake sensor.
7 . The system of claim 1 , wherein the at least one sensor is a steering sensor.
