[0028] exist figure 1 A hydraulic control module 100 for an automatic shifting device 5 is shown in , in which the bias force adjusting device according to the first embodiment is used. The biasing force adjusting means is provided in, for example, the control valve 1, which is an electromagnetic hydraulic type control valve as a hydraulic control valve adapted to a hydraulic control module 100 that controls the supply to an automatic switch for a vehicle. The oil pressure of the blocking device 5. The hydraulic control module 100 controls the pressure of working oil and supplies the working oil to the automatic shifter 5 that gradually changes a gear ratio using a plurality of gears in power transmission. The automatic shift device 5 includes a plurality of clutches 6 each corresponding to a friction element operated according to the pressure of working oil supplied from the hydraulic control module 100 . For convenience, figure 1 Only one of the clutches is shown.

[0095] based on Image 6 A bias force adjusting device according to a second embodiment will be described. The second embodiment differs from the first embodiment in the shape of the adjuster screw.

[0096] like Image 6As shown, the biasing force adjusting portion 50 of the second embodiment includes a housing 31, a pressure receiving portion 32, a spring 33, and an adjuster screw 54 as a biasing force adjusting member. The adjuster screw 54 integrally includes a stopper portion 541 , an external thread portion 542 as a second thread portion, and a restricting portion 543 . The second end 332 of the spring 33 contacts the end surface 344 of the externally threaded portion 542 adjacent to the pressure receiving portion 32 . The stopper part 541 restricts the second end part 332 of the spring 33 from moving in the radial direction. The externally threaded portion 542 has a substantially columnar shape and has external threads on the radially outer side. The external threa...

Abstract

A biasing force adjustment device includes: a cylindrical component having a first thread part; a reciprocate component accommodated in the cylindrical component; a biasing portion that biases the reciprocate component in a first direction; and a biasing force adjustment component that adjusts a biasing force of the biasing portion. The biasing force adjustment component has a second thread part engaged with the first thread part so as to control the position of the biasing force adjustment component relative to the cylindrical component, and a regulation part that regulates movement of the biasing force adjustment component relative to the cylindrical component by being deformed in a radial direction by external force applied in the first direction.

Description

technical field [0001] The present invention relates to a bias force adjusting device, a hydraulic control valve having said bias force adjusting device and a method of manufacturing the bias force adjusting device. Background technique [0002] The hydraulic control module for the automatic shift device switches the shift range of the automatic shift device by controlling the pressure of working oil supplied to the clutch of the automatic shift device. The hydraulic control module is equipped with a pump for supplying hydraulic oil, a hydraulic control valve for controlling the pressure of the hydraulic oil, and a control unit for controlling the hydraulic control valve. A hydraulic control valve includes a valve sleeve having passages communicated to a pump and a clutch, a spool accommodated in the valve sleeve, and an actuator that actuates the spool to reciprocate in the valve sleeve. When the spool reciprocates in the valve sleeve, the pressure of working oil supplied ...
