Abstract
A control unit having a circuit substrate mounted within a housing that is adapted to be mounted upon a hydraulic valve body with a coil spacer mounted upon said substrate. The coil spacer including at least one coil support ring having resilient member extending in a radial direction from the edge of the ring into the center of the ring. The control unit also including a solenoid coil and flux casing assembly mounted upon the coil spacer ring with the solenoid coil and flux casing assembly flexing the resilient member such that the resilient member urges flux casing away from the coil spacer.
Claims17
A control unit for a vehicle brake system, the control unit comprising:
- a housing adapted to be mounted upon a hydraulic valve body;
- a circuit substrate mounted within said housing;
- a coil spacer mounted upon said substrate;
- said coil spacer including at least one coil support ring having a resilient member extending in a radial direction from the edge of said ring into the center of said ring;
- and
- a solenoid coil and flux casing assembly mounted upon said coil spacer ring;
- said solenoid coil and flux casing assembly flexing said resilient member such that said resilient member urges said flux casing away from said coil spacer.
A method for assembling a control unit for a vehicle brake system, the method comprising the steps of:
- (a) providing a coil spacer that includes a base having at least one coil support ring, the coil support ring including resilient member extending in a radial direction from the edge thereof and into the center of the support ring;
- (b) mounting at least one solenoid coil and flux casing assembly upon the coil spacer ring with the coil and flux casing assembly flexing the resilient member such that the resilient member urges the flux casing away from the coil spacer base;
- (c) mounting the coil spacer upon a circuit substrate to form an assembly;
- (d) inserting the circuit substrate and coil spacer assembly into a housing.
