摘要:
The present disclosure increases the braking force of a parking spring brake mechanism without enlarging a device and without substantial increase in cost. The subject of the present disclosure is a brake cylinder device 2 provided with a parking spring brake mechanism 40 wherein a first piston 43 moves in a prescribed braking direction C. The brake cylinder device 2 is provided with a brake force transmitting section 37 having an inclined surface 38 that is inclined so as to press a brake output section 7 in an advancement direction A by moving along with the first piston 43 in the braking direction C. The inclined surface 38 includes a first inclined surface 38a provided in a distal end portion, and a second inclined surface 38b provided in a proximal end portion and inclined more than the first inclined surface 38a with respect to the advancement direction A.
摘要:
The purpose of the invention is to ensure proper action of a latch member. A brake cylinder device (2) having a parking spring brake mechanism (25), provided with: a clutch mechanism (27) configured so as to transmit or block urging force of a piston (35) to or from a brake force transmitting unit (14); a latch member (49) for restricting displacement of the brake force transmitting unit (14) relative to the piston (35) by engaging with the clutch mechanism (27), and allowing displacement of the brake force transmitting unit (14) relative to the piston (35) by disengaging from the clutch mechanism (27); a latch lock member (51) for engaging at an inclined part with a protruding part of the latch member (49); and a rotation-preventing part (5) for preventing the latch lock member (51) from rotating.
